Controversy exists as to whether sinus thrombosis is the cause or the result of dural arteriovenous fistula (DAVF) and to whether DAVF are congenital or acquired lesions, especially in children. An infant presented with rupture of an anterior communicating artery aneurysm diagnosed with computed tomography angiography and catheter angiography. Pretreatment hospital course was complicated by extensive dural sinus thrombosis. Subsequent arteriography showed a new adult-type dural arteriovenous fistula to the previously thrombosed right sigmoid sinus. This is the first report of definitive angiographic documentation of the development of an adult-type DAVF after recanalization of a thrombosed dural sinus in a child. This case confirms the acquired etiology of at least one type of DAVF in children, even at this young age. We review the previously documented cases of formation of DAVF subsequent to sinus thrombosis with serial angiography in adults. (orig.)

Breast cancer remains one of the leading causes of morbidity and mortality for all women in the US. Current research has focused on the psychological relationship and not the sociological relationship between emotions and the experience of breast cancer survivors. This paper focuses on the emotion work involved in self-disclosing a breast cancer diagnosis in a racially or ethnically diverse population. The participants (n = 176) selected for this study were African American, Asian American, Latina, and Caucasian women who had been diagnosed with stages 0, I, or II breast cancer within the past 4 years. They completed an in-depth qualitative interview on self-disclosure and social support. The results indicate self-disclosing was done at a time when important decisions about treatment needed to be made. Different strategies for disclosure were used, all of which entailed emotion work. Respondents talked about the various elements of emotion work in the disclosure process including: managing others' worry, protecting and soothing others, and educating and instructing others. For many respondents, disclosure without calculating emotional management meant opening up to others which meant support and an increase in emotional resources. The findings in this paper have implications for women with breast cancer and demonstrate the need for women to be involved in honest disclosure and less emotional management of others' feelings. There is also a need for education about the nature of the cancer experience among people who are not well educated about the treatment and consequences of cancer. This need may be even stronger among racial and ethnic minorities.

Dural arteriovenous fistula as a treatable dementia.

Dementia is a chronic loss of neurocognitive function that is progressive and irreversible. Although rare, dural arteriovenous fistulas (DAVFs) could present with a rapid decline in neurocognitive function with or without Parkinson-like symptoms. DAVFs represent a potentially treatable and reversible cause of dementia. Here, we report the case of an elderly woman diagnosed with a DAVF after presenting with new-onset seizures, deteriorating neurocognitive function, and Parkinson-like symptoms.

Full Text Available Objectives: The purpose of this study was to establish the role of the liquid embolic agent, ONYX, in the treatment of cranial dural arteriovenous fistulae (DAVFs and to redefine the indications, techniques and outcomes of treatment with ONYX. Materials and Methods: This is a retrospective study of 25 DAVF patients who underwent endovascular treatment with ONYX between February 2006 and July 2008. All patients of DAVF presenting in this period were treated with ONYX. Results: Anatomic cure (i.e., complete angiographic closure of the fistula was achieved in a single session and through a single arterial pedicle injection in 21 out of 25 patients (cure rate of 84%. Out of four patients with residual fistulae, one achieved cure that was evident on a control angiogram obtained at 3 months while three had no vascular access for further embolization and so were referred for radiosurgery. There was only one recurrence seen in angiograms obtained at the end of one year and this patient was re-embolized successfully with ONYX. Complications were seen in two patients. Conclusion: ONYX embolization of DAVFs has revolutionized the endovascular treatment of DAVFs, achieving high cure rates in a single session with minimal complications. Transarterial ONYX embolization should be the first option for all locations, except cavernous DAVFs.

2017-09-01

Disclosing amyloid status to cognitively normal individuals remains controversial given our lack of understanding the test's clinical significance and unknown psychological risk. We assessed the effect of amyloid status disclosure on anxiety and depression before disclosure, at disclosure, and 6 weeks and 6 months postdisclosure and test-related distress after disclosure. Clinicians disclosed amyloid status to 97 cognitively normal older adults (27 had elevated cerebral amyloid). There was no difference in depressive symptoms across groups over time. There was a significant group by time interaction in anxiety, although post hoc analyses revealed no group differences at any time point, suggesting a minimal nonsustained increase in anxiety symptoms immediately postdisclosure in the elevated group. Slight but measureable increases in test-related distress were present after disclosure and were related to greater baseline levels of anxiety and depression. Disclosing amyloid imaging results to cognitively normal adults in the clinical research setting with pre- and postdisclosure counseling has a low risk of psychological harm.

Disclosing harmful medical errors to patients: tackling three tough cases.

Science.gov (United States)

Gallagher, Thomas H; Bell, Sigall K; Smith, Kelly M; Mello, Michelle M; McDonald, Timothy B

2009-09-01

A gap exists between recommendations to disclose errors to patients and current practice. This gap may reflect important, yet unanswered questions about implementing disclosure principles. We explore some of these unanswered questions by presenting three real cases that pose challenging disclosure dilemmas. The first case involves a pancreas transplant that failed due to the pancreas graft being discarded, an error that was not disclosed partly because the family did not ask clarifying questions. Relying on patient or family questions to determine the content of disclosure is problematic. We propose a standard of materiality that can help clinicians to decide what information to disclose. The second case involves a fatal diagnostic error that the patient's widower was unaware had happened. The error was not disclosed out of concern that disclosure would cause the widower more harm than good. This case highlights how institutions can overlook patients' and families' needs following errors and emphasizes that benevolent deception has little role in disclosure. Institutions should consider whether involving neutral third parties could make disclosures more patient centered. The third case presents an intraoperative cardiac arrest due to a large air embolism where uncertainty around the clinical event was high and complicated the disclosure. Uncertainty is common to many medical errors but should not deter open conversations with patients and families about what is and is not known about the event. Continued discussion within the medical profession about applying disclosure principles to real-world cases can help to better meet patients' and families' needs following medical errors.

Patients on hemodialysis are better served by a proximal arteriovenous fistula for long-term venous access.

LENUS (Irish Health Repository)

Sultan, Sherif

2012-11-01

Patients with end-stage renal disease should have arteriovenous fistula (AVF) formation 3 to 6 months prior to commencing hemodialysis (HD). However, this is not always possible with strained health care resources. We aim to compare autologous proximal AVF (PAVF) with distal AVF (DAVF) in patients already on HD. Primary end point is 4-year functional primary. Secondary end point is freedom from major adverse clinical events (MACEs). From January 2003 to June 2009, out of 495 AVF formations, 179 (36%) patients were already on HD. These patients had 200 AVF formations (49 DAVF vs 151 PAVF) in arms in which no previous fistula had been formed. No synthetic graft was used. Four-year primary functional patency significantly improved with PAVF (68.9% ± SD 8.8%) compared to DAVF (7.3% ± SD 4.9%; P < .0001). Five-year freedom from MACE was 85% with PAVF compared to 40% with DAVF (P < .005). Proximal AVF bestows long-term functional access with fewer complications compared to DAVF for patients already on HD.

Dural arteriovenous fistulae (DAVF) occasionally lead to cognitive disorders whose reversibility after DAVF treatment remains unclear. We studied changes on pre- and post-treatment magnetic resonance imaging (MRI) and single photon emission computed tomography (SPECT) scans in ten patients with cognitive disorder due to DAVF. We studied the symptoms, pre- and post-treatment MRI scans, SPECT findings, and mini-mental state examination (MMSE) and treatment results in ten patients with cognitive disorder due to DAVF. They were divided into two groups; the post-treatment MMSE score exceeded 25 points in group 1 (n = 6) and was lower than 24 points in group 2 (n = 4). In the six group 1 patients, pretreatment diffusion-weighted images (DWI) showed hyperintense areas, and SPECT scans demonstrated the preservation of vasoreactivity after acetazolamide challenge. In the four group 2 patients, pretreatment SPECT demonstrated hypoperfusion areas that coincided with the hyperintense areas seen on DWI; there were areas with marked disturbance in vasoreactivity. The post-treatment MMSE score in groups 1 and 2 improved by 13.7 ± 2.4 and 3.8 ± 1.0 points, respectively; the difference was significant at p < 0.01. In patients with cognitive disorder due to DAVF, the preservation of vasoreactivity on SPECT after acetazolamide challenge indicates that their cognitive disorder may be reversible by DAVF treatment.

To review the findings of interdisciplinary team evaluations of children who disclosed sexual abuse via facilitated communication. Case series. Tertiary care hospital outpatient child sexual abuse program in central New York. Between January 1990 and March 1993, 13 children who disclosed sexual abuse via facilitated communication and were referred to a university hospital child abuse referral and evaluation center. The range of previously determined developmental diagnosis included mental retardation, speech delay, and autism. None. Medical records were reviewed for (1) disclosure, (2) physical evidence, (3) child's behavioral and medical history, (4) disclosures by siblings, (5) perpetrator's confession, (6) child protective services determinations, and (7) court findings. Four children had evidence of sexual abuse: two had physical findings consistent with sexual abuse, one also disclosed the allegation verbally, and one perpetrator confessed. These results neither support nor refute validation of facilitated communication. However, many children had other evidence of sexual abuse, suggesting that each child's case should be evaluated without bias.

The prevalence and quality of silent, socially silent, and disclosed autobiographical memories across adulthood.

Alea, Nicole

2010-02-01

Two separate studies examined the prevalence and quality of silent (infrequently recalled), socially silent (i.e., recalled but not shared), and disclosed autobiographical memories. In Study 1 young and older men and women remembered positive events. Positive memories were more likely to be disclosed than to be kept socially silent or completely silent. However, socially silent and disclosed memories did not differ in memory quality: the memories were equally vivid, significant, and emotional. Silent memories were less qualitatively rich. This pattern of results was generally replicated in Study 2 with a lifespan sample for both positive and negative memories, and with additional qualitative variables. The exception was that negative memories were kept silent more often. Age differences were minimal. Women disclosed their autobiographical memories more, but men told a greater variety of people. Results are discussed in terms of the functions that memory telling and silences might serve for individuals.

Background Intracranial dural arteriovenous fistulae (DAVF) may present a treatment challenge. Endovascular embolization is in most cases the first line of treatment but does not always achieve cure. Gamma Knife (GK) radiosurgery represents an alternative treatment option, and the purpose of this study was to further evaluate its utility. Methods We reviewed all cases of DAVF treated between 2009 and 2016 at our institution with GK radiosurgery independently, or following failed/refused endovascular or surgical management. Patients’ clinical files, radiological images, catheter angiograms, and surgical DAVF disconnection reports were retrospectively reviewed. Results Sixteen DAVF (14 patients) treated by GK radiosurgery were identified. Eleven fistulae were aggressive and five were benign. Marginal doses ranged from 15 to 25 Gy. Target volumes ranged from 0.04 to 4.47 cm3. In all symptomatic patients, GK treatment resulted in symptom palliation. In 13/15 lesions, cure of symptoms (86.0%) was reported. One lesion was asymptomatic. Angiographic cure was achieved in eight cases (50%), small residual DAVF occurred in four, and four were unchanged. One patient developed headache that resolved at one year. No hemorrhage occurred during the follow-up period. There was no significant association between Borden type and cure rate. Prior failed endovascular treatment and small target volume were associated with lower rates of cure. Conclusions Stereotactic radiosurgery is viable treatment for DAVF. It is very effective in palliating symptoms as a de novo approach or adjunctive to endovascular therapy. In our experience it is only somewhat effective in achieving complete angiographic cure.

Keeping the door open: Exploring experiences of, and responses to, university students who disclose mental illness

Directory of Open Access Journals (Sweden)

2012-06-01

Full Text Available University educators increasingly manage situations where students disclose serious mental health issues. This is a significant issue, particularly for health and human service professions, as the importance of valuing the lived experience of mental illness lies alongside concerns for professional practice standards. Thus the responsibilities of students to disclose their mental health status and the responsibilities of Universities to provide appropriate support within established disability frameworks must be clear. However, students often do not know who they should disclose to, what will happen to disclosed information, and who has access to this information. Student's often fear embarrassment, stigma, and shame about disclosing mental illness, which is compounded by the diverse attitudes, experiences, and beliefs of educators. Consequently, this paper will review existing literature on university responses to, and students’ experiences of, mental illness in order to set a research agenda for this topic. The authors argue that such research must be undertaken urgently, in a context of inclusivity in higher education that gives voice to the experiences of students, their families and carers, university staff, and practitioners in the field.

Willingness to disclose child maltreatment: CSA vs other forms of child abuse in relation to gender.

Science.gov (United States)

Lev-Wiesel, Rachel; First, Maya

2018-05-01

The aim of the study was to examine the role of gender in willingness to disclose childhood sexual abuse (CSA) compared to other forms of abuse (physical, emotional and neglect) in young adolescents. Willingness was examined through two terms: reluctance- the level of unwillingness or disinclination to disclose, and urge-the need to share in order to get rid of unbearable feelings. The sample consisted of 3,156 boys (n = 1,544) and girls (n = 1,612) between the ages of 11-16 who reported having been abused at least once during their life. Participants were divided into three groups: experiencing other than CSA, sexual abuse with no physical contact, and sexual abuse with physical contact. Regarding measures, a self-report questionnaire incorporating the following instruments was administered: Demographics, the Juvenile Victimization Questionnaire (JVQ), and the Disclosure of Trauma Questionnaire (DTQ). Study results indicated that CSA victims were more reluctant to disclose than victims of other than CSA forms of abuse. The more severe the CSA (physical contact) the lower was the willingness to disclose. Boys were more reluctant than girls to disclose sexual abuse whether or not it involved physical contact. Reluctance to disclose was positively associated with emotional reactions to disclosure while urge to talk was negatively correlated with emotional reactions to disclosure. Copyright © 2018.

Objective: To evaluate the assistant techniques in performing transarterial embolization of intracranial dural arteriovenous fistulas (DAVF) when routine super-selective catheterization with microcatheter fails. Methods: Temporary balloon occlusion of the parent artery was adopted in 4 cases of anterior fossa DAVF and in one case of tentorial DAVF, and permanent occlusion of the distal main trunk with coils was carried out in one tentorial DAVF in order to help the super-selective catheterization. Results: The microcatheter was successfully advanced to, or near, the nidus with the help of these assistant techniques and all 6 cases were cured with single session. After the surgery no operation-related complications occurred. Conclusion: Our preliminary results indicate that the assistant techniques, including temporary balloon occlusion of the parent artery and permanent occlusion of the distal main trunk with coils, are a safe and effective method which can reliably help the successful performance of microcatheter catheterization, it can be safely used in complex cases when routine super-selective catheterization fails.

2017-08-01

Patients with cavernous sinus dural arteriovenous fistulas (CS dAVFs) with cortical venous varix are indicated for aggressive treatment because of the associated risk for intracranial hemorrhage. We present a case of surgical transvenous embolization in an 84-year-old woman with CS dAVF who presented with massive intracerebral hematoma. Cerebral angiograms revealed the dural AVF drained only into the superficial middle cerebral vein. Because an emergent mass reduction and prevention of rebleeding were necessary, single-session hematoma removal and transcranial embolization of a CS dAVF were performed in the neurosurgical operating room, using a mobile C-arm fluoroscopy. After the right frontotemporal craniotomy, intracerebral hematoma was removed and coil packing of the affected cavernous sinus was successfully performed via the dilated superficial middle cerebral vein. The transcortical vein approach enables occlusion of CS dAVF with isolated cortical venous drainage and may be a valuable alternative approach for some cases needed emergency craniotomy.

Medullary Venous Hypertension Secondary to a Petrous Apex Dural Arteriovenous Fistula: A Case Report

Directory of Open Access Journals (Sweden)

Meghan Murphy

2012-11-01

Full Text Available Background: Dural arteriovenous fistulae (dAVF are common intracranial vascular lesions typically becoming symptomatic with cortical venous hypertension and possible hemorrhage. Here, we present a case illustration of a petrous apex dAVF with marked medullary venous hypertension and a unique clinical presentation. Methods: Case report. Results: A 72-year-old female, whose clinical progression was significant for altered mental status and progressive weakness, presented with diplopia, right leg paresis, and ataxia. Magnetic resonance imaging revealed edema involving the medulla. On digital subtraction cerebral angiogram, the patient was found to have a petrous apex dAVF, Cognard type IV. Following treatment with Onyx embolization, her symptoms rapidly improved, with complete resolution of diplopia and drastic improvement of her ataxia. Conclusion: The importance of this case is in the presentation and deterioration of the clinical exam, resembling an acute ischemic event. Further, this case illustrates that dAVF may cause venous hypertension with rapid onset of focal neurologic symptoms not exclusive to cortical locations.

Physician privacy concerns when disclosing patient data for public health purposes during a pandemic influenza outbreak.

Privacy concerns by providers have been a barrier to disclosing patient information for public health purposes. This is the case even for mandated notifiable disease reporting. In the context of a pandemic it has been argued that the public good should supersede an individual's right to privacy. The precise nature of these provider privacy concerns, and whether they are diluted in the context of a pandemic are not known. Our objective was to understand the privacy barriers which could potentially influence family physicians' reporting of patient-level surveillance data to public health agencies during the Fall 2009 pandemic H1N1 influenza outbreak. Thirty seven family doctors participated in a series of five focus groups between October 29-31 2009. They also completed a survey about the data they were willing to disclose to public health units. Descriptive statistics were used to summarize the amount of patient detail the participants were willing to disclose, factors that would facilitate data disclosure, and the consensus on those factors. The analysis of the qualitative data was based on grounded theory. The family doctors were reluctant to disclose patient data to public health units. This was due to concerns about the extent to which public health agencies are dependable to protect health information (trusting beliefs), and the possibility of loss due to disclosing health information (risk beliefs). We identified six specific actions that public health units can take which would affect these beliefs, and potentially increase the willingness to disclose patient information for public health purposes. The uncertainty surrounding a pandemic of a new strain of influenza has not changed the privacy concerns of physicians about disclosing patient data. It is important to address these concerns to ensure reliable reporting during future outbreaks.

2014-04-15

This study aimed to evaluate the feasibility of non-contrast-enhanced 4D magnetic resonance angiography (NCE 4D MRA) with signal targeting with alternative radiofrequency (STAR) spin labeling and variable flip angle (VFA) sampling in the assessment of dural arteriovenous fistula (DAVF) in the transverse sinus. Nine patients underwent NCE 4D MRA for the evaluation of DAVF in the transverse sinus at 3 T. One patient was examined twice, once before and once after the interventional treatment. All patients also underwent digital subtraction angiography (DSA) and/or contrast-enhanced magnetic resonance angiography (CEMRA). For the acquisition of NCE 4D MRA, a STAR spin tagging method was used, and a VFA sampling was applied in the data readout module instead of a constant flip angle. Two readers evaluated the NCE 4D MRA data for the diagnosis of DAVF and its type with consensus. The results were compared with those from DSA and/or CEMRA. All patients underwent NCE 4D MRA without any difficulty. Among seven patients with patent DAVFs, all cases showed an early visualization of the transverse sinus on NCE 4D MRA. Except for one case, the type of DAVF of NCE 4D MRA was agreed with that of reference standard study. Cortical venous reflux (CVR) was demonstrated in two cases out of three patients with CVR. NCE 4D MRA with STAR tagging and VFA sampling is technically and clinically feasible and represents a promising technique for assessment of DAVF in the transverse sinus. Further technical developments should aim at improvements of spatial and temporal coverage. (orig.)

How Radiation Oncologists Would Disclose Errors: Results of a Survey of Radiation Oncologists and Trainees

International Nuclear Information System (INIS)

Evans, Suzanne B.; Yu, James B.; Chagpar, Anees

2012-01-01

Purpose: To analyze error disclosure attitudes of radiation oncologists and to correlate error disclosure beliefs with survey-assessed disclosure behavior. Methods and Materials: With institutional review board exemption, an anonymous online survey was devised. An email invitation was sent to radiation oncologists (American Society for Radiation Oncology [ASTRO] gold medal winners, program directors and chair persons of academic institutions, and former ASTRO lecturers) and residents. A disclosure score was calculated based on the number or full, partial, or no disclosure responses chosen to the vignette-based questions, and correlation was attempted with attitudes toward error disclosure. Results: The survey received 176 responses: 94.8% of respondents considered themselves more likely to disclose in the setting of a serious medical error; 72.7% of respondents did not feel it mattered who was responsible for the error in deciding to disclose, and 3.9% felt more likely to disclose if someone else was responsible; 38.0% of respondents felt that disclosure increased the likelihood of a lawsuit, and 32.4% felt disclosure decreased the likelihood of lawsuit; 71.6% of respondents felt near misses should not be disclosed; 51.7% thought that minor errors should not be disclosed; 64.7% viewed disclosure as an opportunity for forgiveness from the patient; and 44.6% considered the patient's level of confidence in them to be a factor in disclosure. For a scenario that could be considerable, a non-harmful error, 78.9% of respondents would not contact the family. Respondents with high disclosure scores were more likely to feel that disclosure was an opportunity for forgiveness (P=.003) and to have never seen major medical errors (P=.004). Conclusions: The surveyed radiation oncologists chose to respond with full disclosure at a high rate, although ideal disclosure practices were not uniformly adhered to beyond the initial decision to disclose the occurrence of the error.

Duty to disclose in medical genetics: a legal perspective.

Science.gov (United States)

Pelias, M Z

1991-06-01

As technical knowledge and public information in medical genetics continue to expand, the geneticist may expect to be held responsible for informing patients and clients about new developments in research and diagnosis. The long legal evolution of the physician's duty to disclose, and more recent findings of a physician's duty to recall former patients to inform them about newly discovered risks of treatment, indicate that medical geneticists may have a duty to disclose both current and future information about conditions that are or could be inherited. Recent case law supports findings of professional liability for both present and future disclosure, even in the absence of an active physician-patient relationship. The requirement of candid and complete disclosure will affect the counseling approach in testing for deleterious genes and in providing medical treatment for minors with hereditary diseases. Finding a duty to recall may impose further professional burdens on the geneticist to reach beyond the immediate counseling arena and to recontact patients, perhaps years after their initial visit to genetics clinic.

[Dural arteriovenous fistula involving the superior sagittal and transverse-sigmoid sinuses, treated by thrombolysis: case report].

1997-07-01

A rare case of dural arteriovenous fistula (DAVF) in the superior sagittal sinus (SSS), the transverse sinus and the sigmoid sinus is reported. A 64-year-old man, who had had an episode of temporary visual disturbance after moderate fever for a week about 20 years before, was aware of loss of visual acuity and reduced field of view in the right eye. When he was introduced to our outpatient service, increased intracranial pressure (ICP) was detected by lumbar puncture. Cerebral angiograms showed bilateral DAVFs both in the posterior fossa and the SSS concomitant with thrombosis in the transverse sinus, sigmoid sinus and SSS. Afterwards, endovascular transarterial embolization through bilateral occipital, posterior auricular and left middle meningeal, superior temporal arteries was carried out. In addition, transvenous thrombolytic therapy using a catheter inserted into SSS resulted in the improvement of his visual problems. Although he was discharged at once, he was readmitted to our department with Foster Kennedy syndrome and increased ICP. Cerebral angiograms showed recurrence of both DAVF and sinus thrombosis. Transarterial embolization was performed again resulting in a significant reduction of DAVF, and his visual acuity was recovered to a moderate degree. The origin of DAVF is still controversial. Although two theories, "congenital" and "acquired", are put forward, it has been thought that both factors play important roles. In our case, the patient had stenosis in the jugular canal portions of the sigmoid sinus. In addition, sinus thrombosis seemed to have occurred. It is thought that increased intrasinus pressure may have lead to communication with surrounding arteries through existing dural vessels. We applied transvenous thrombolytic therapy in this case. Our result suggests that we should consider this therapy for some cases of DAVF.

MRI and phase-contrast MR angiography (PC MRA) were obtained in 13 patients with angiographically confirmed intracranial dural arteriovenous fistulae (DAVF). Three- and two-dimensional PC MRA was obtained with low (6-20 cm/s) and high (>40 cm/s) velocity encoding along the three main body axes. MRI showed focal or diffuse signal abnormalities in the brain parenchyma in six patients, dilated cortical veins in seven, venous pouches in four with type IV DAVF and enlargement of the superior ophthalmic vein in three patients with DAVF of the cavernous sinus. However, it showed none of the fistula sites and did not allow reliable identification of feeding arteries. 3D PC MRA enabled identification of the fistula and enlarged feeding arteries in six cases each. Stenosis or occlusion of the dural sinuses was detected in six of eight cases on 3D PC MRA with low velocity encoding. In six patients with type II DAVF phase reconstruction of 2D PC MRA demonstrated flow reversal in the dural sinuses or superior ophthalmic vein. (orig.)

Concomitant seizures and exophthalmos in the context of a temporal dural arteriovenous fistula (dAVF) has not been described before. Here, we report a 55-year-old-male who presented with an 8-month history of progressive painless exophthalmos of his left eye, conjunctival chemosis, reduced vision and new onset complex partial seizures. Cerebral angiography demonstrated Cognard Type IIa left cerebral dAVF fed by branches from the left occipital artery and an accessory meningeal artery, with drainage to the superior ophthalmic vein. Following surgical obliteration of dAVF feeding vessels, our patient had dramatic improvement in visual acuity, proptosis and chemosis along with cessation of clinical seizures.

Many soldiers with mental illness (SWMIs) struggle with the decision whether to disclose their condition in or outside the military. This study therefore explored views on (self-)labeling as 'mentally ill', experiences of discrimination and coping, risks and benefits of (non-)disclosure, service use, disclosure decisions and consequences of disclosing. Active-duty SWMIs as well as soldiers without mental illness (commanding officers; enlisted ranks) and military social workers participated in focus groups. Transcripts were analyzed using qualitative content analysis. SWMIs perceived negative stereotypes about their group (weakness, incompetence, blame, malingering) and saw stigma as a barrier to help-seeking. Being labeled 'mentally ill' was seen as harmful for one's career. Self-labeling led to poor self-esteem, greater need for help and feelings of weakness. Many SWMIs had experienced discrimination, such as gossip or inappropriate comments. Social isolation was a disadvantage of secrecy. Most SWMIs preferred selective disclosure and many did not disclose to their family. Military staff without mental illness expressed partly different views and described organizational challenges posed by SWMIs. Our findings suggest that disclosure decisions are personal and difficult and that stigma remains a barrier to re-integration and recovery of SWMIs in the military. Implications for interventions to support SWMIs are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

PurposeCranial nerve dysfunction (CND) is not uncommon in patients with cavernous dural arteriovenous fistulas (cDAVFs), and may represent an initial manifestation or a complication after endovascular treatment. This study evaluated the outcome of CND associated with cDAVFs after transvenous embolization (TVE) using Onyx.Materials and MethodsForty-one patients with cDAVFs were treated with TVE in our department between April 2009 and October 2013. For each patient, clinical and radiologic records were retrospectively reviewed and evaluated, with an emphasis placed on evaluating the outcomes of the pre-existing cDAVF-induced CND and the TVE-induced CND.ResultsOf the 41 cases, 25 had a history of preoperative CND. Postoperatively, gradual remission to complete recovery (CR) within 8 months was observed in 17 of these cases, transient aggravation in 7, and significant improvement to be better than preoperative function but no CR in 1. All aggravation of CND occurred immediately or within 1 day after TVE and resolved completely within 5 months. Nine patients developed new CND after TVE. New CND occurred during the perioperative period in 8 cases, but all cases resolved completely within 15 days–6 months. Delayed CND was observed in 3 cases with a time lag of 3–25 months after TVE. Two of these completely resolved within 20 days–1 month and the remaining case significantly improved.ConclusionBoth the pre-existing cDAVF-induced CND and the TVE-induced new or aggravated CND completely resolved in almost all cases after embolization with Onyx.

2016-10-01

Full disclosure of harmful errors to patients, including a statement of regret, an explanation, acceptance of responsibility and commitment to prevent recurrences is the current standard for physicians in the USA. To examine the extent to which primary care physicians' perceptions of event-level, physician-level and organisation-level factors influence intent to disclose a medical error in challenging situations. Cross-sectional survey containing two hypothetical vignettes: (1) delayed diagnosis of breast cancer, and (2) care coordination breakdown causing a delayed response to patient symptoms. In both cases, multiple physicians shared responsibility for the error, and both involved oncology diagnoses. The study was conducted in the context of the HMO Cancer Research Network Cancer Communication Research Center. Primary care physicians from three integrated healthcare delivery systems located in Washington, Massachusetts and Georgia; responses from 297 participants were included in these analyses. The dependent variable intent to disclose included intent to provide an apology, an explanation, information about the cause and plans for preventing recurrences. Independent variables included event-level factors (responsibility for the event, perceived seriousness of the event, predictions about a lawsuit); physician-level factors (value of patient-centred communication, communication self-efficacy and feelings about practice); organisation-level factors included perceived support for communication and time constraints. A majority of respondents would not fully disclose in either situation. The strongest predictors of disclosure were perceived personal responsibility, perceived seriousness of the event and perceived value of patient-centred communication. These variables were consistently associated with intent to disclose. To make meaningful progress towards improving disclosure; physicians, risk managers, organisational leaders, professional organisations and

OBJECTIVE Clival epidural-osseous dural arteriovenous fistula (DAVF) is often associated with a large nidus, multiple arterial feeders, and complex venous drainage. In this study the authors report the outcomes of clival epidural-osseous DAVFs treated using Gamma Knife surgery (GKS). METHODS Thirteen patients with 13 clival epidural-osseous DAVFs were treated with GKS at the authors' institution between 1993 and 2015. Patient age at the time of GKS ranged from 38 to 76 years (median 55 years). Eight DAVFs were classified as Cognard Type I, 4 as Type IIa, and 1 as Type IIa+b. The median treatment volume was 17.6 cm 3 (range 6.2-40.3 cm 3 ). The median prescribed margin dose was 16.5 Gy (range 15-18 Gy). Clinical and radiological follow-ups were performed at 6-month intervals. Patient outcomes after GKS were categorized as 1) complete improvement, 2) partial improvement, 3) stationary, and 4) progression. RESULTS All 13 patients demonstrated symptomatic improvement, and on catheter angiography 12 of the 13 patients had complete obliteration and 1 patient had partial obliteration. The median follow-up period was 26 months (range 14-186 months). The median latency period from GKS to obliteration was 21 months (range 8-186 months). There was no intracranial hemorrhage during the follow-up period, and no deaths occurred. Two adverse events were observed following treatment, and 2 patients required repeat GKS treatment with eventual complete obliteration. CONCLUSIONS Gamma Knife surgery offers a safe and effective primary or adjuvant treatment modality for complex clival epidural-osseous DAVFs. All patients in this case series demonstrated symptomatic improvement, and almost all patients attained complete obliteration.

Angio-Architectural Features of High-Grade Intracranial Dural Arteriovenous Fistulas: Correlation With Aggressive Clinical Presentation and Hemorrhagic Risk.

High-grade dural arteriovenous fistulas (dAVFs) can present shunts with very different angio-architectural characteristics. Specific hemodynamic factors may affect clinical history and determine very different clinical courses. To evaluate the relationship between some venous angio-architectural features in high-grade dAVFs and clinical presentation. Specific indicators of moderate or severe venous hypertension were analyzed, such as altered configurations of the dural sinuses (by a single or a dual thrombosis), or overload of cortical vessels (restrictions of outflow, pseudophlebitic cortical vessels, and venous aneurysms). The institutional series was retrospectively reviewed (49 cases), and the pattern of venous drainage was analyzed in relationship with clinical presentation (benign/aggressive/hemorrhage). Thirty-five of 49 cases displayed cortical reflux (high-grade dAVFs). This subgroup displayed a benign presentation in 31.42% of cases, an aggressive in 31.42%, and hemorrhage in 37.14%. Our data confirm that within high-grade dAVFs, 2 distinct subpopulations exist according to severity of clinical presentation. Some indicators we examined showed correlation with aggressive nonhemorrhagic manifestations (outflow restriction and pseudophlebitic cortical vessels), while other showed a correlation with hemorrhage (dual thrombosis and venous aneurysms). Current classifications appear insufficient to identify a wide range of conditions that ultimately determine the organization of the cortical venous drainage. Intermediate degrees of venous congestion correlate better with the clinical risk than the simple definition of cortical reflux. The angiographic aspects of venous drainage presented in this study may prove useful to assess dAVF hemodynamic characteristics and identify conditions at higher clinical risk.

1999-01-01

This study approaches the social and cultural profile concerning risk for HIV infection in women, describing some epidemiological variables and disclosing reports of risk situations, the meaning of living with AIDS, and support received. A semi-structured questionnaire was used to interview 25 women from the University Hospital of the Federal University of Rio de Janeiro, prior to the availability of multi-drug treatment. The majority reported limited schooling, were housewives or engaged in under-skilled occupations, and had family incomes lower than average for users of this public teaching hospital. The view of AIDS as "someone else's disease" was prevalent, and STDs were perceived as male infections, although several women reported episodes of STDs prior to HIV. They had received their diagnosis and initial medical care only after their partners' and/or children's illness or death. The study points to preventive strategies reinforcing these silent women's bargaining power, acting on men as potential active participants in reproductive health programs that incorporate STD/AIDS issues.

Disclosing medical mistakes: a communication management plan for physicians.

Science.gov (United States)

Petronio, Sandra; Torke, Alexia; Bosslet, Gabriel; Isenberg, Steven; Wocial, Lucia; Helft, Paul R

2013-01-01

There is a growing consensus that disclosure of medical mistakes is ethically and legally appropriate, but such disclosures are made difficult by medical traditions of concern about medical malpractice suits and by physicians' own emotional reactions. Because the physician may have compelling reasons both to keep the information private and to disclose it to the patient or family, these situations can be conceptualized as privacy dilemmas. These dilemmas may create barriers to effectively addressing the mistake and its consequences. Although a number of interventions exist to address privacy dilemmas that physicians face, current evidence suggests that physicians tend to be slow to adopt the practice of disclosing medical mistakes. This discussion proposes a theoretically based, streamlined, two-step plan that physicians can use as an initial guide for conversations with patients about medical mistakes. The mistake disclosure management plan uses the communication privacy management theory. The steps are 1) physician preparation, such as talking about the physician's emotions and seeking information about the mistake, and 2) use of mistake disclosure strategies that protect the physician-patient relationship. These include the optimal timing, context of disclosure delivery, content of mistake messages, sequencing, and apology. A case study highlighted the disclosure process. This Mistake Disclosure Management Plan may help physicians in the early stages after mistake discovery to prepare for the initial disclosure of a medical mistakes. The next step is testing implementation of the procedures suggested.

Onyx embolization as a first line treatment for intracranial dural arteriovenous fistulas with cortical venous reflux

International Nuclear Information System (INIS)

Panagiotopoulos, V.; Forsting, M.; Wanke, I.; Moeller-Hartmann, W.; Asgari, S.; Sandalcioglu, I.E.

2009-01-01

Our purpose was to present our experience regarding embolization of intracranial dural arteriovenous fistulas (DAVFs) with cortical venous reflux using Onyx, a non-adhesive liquid embolic agent. From January 2006 to December 2007, 16 patients (12 men and 4 women) with a mean age of 61 years (range 42 - 78) with an intracranial DAVF with cortical venous reflux underwent at least one transarterial embolization using Onyx. According to the Cognard classification, 2 lesions were grade V, 5 were grade IV, 6 were grade III, 2 were grade IIa+b, and 1 was grade IIb. The clinical presentation included 5 hemorrhagic deficits, 10 non-hemorrhagic manifestations, and 1 patient was asymptomatic. Twenty-four embolization sessions were performed in 16 patients with an average of 3 arterial feeders (range 1 - 9) embolized per DAVF. Immediately after embolization, complete occlusion was achieved in 9 / 16 (56 %) patients after the first session. Further postembolization surgical treatment was performed in 3 patients. Partial reperfusion occurred in 1 patient at the time of mean follow-up of 3.7 months (range 0 - 12). Treatment has been completed for 11 / 16 patients with angiographic cure in 10 / 11 (91 %). An infratentorial bleeding complication related to embolization occurred in one patient with temporary worsening of the patient's gait disturbance. At the time of mean clinical follow-up of 4.5 months (range 0 - 12), no procedure-related permanent morbidity was added to our cohort. According to our experience, embolization of intracranial DAVFs with cortical venous drainage using Onyx is feasible with promising results, indicating stability at the time of mid-term follow-up. In very complex DAVFs additional embolization material might be necessary, and in some cases surgery is warranted. (orig.)

Towards Identifying and Disclosing Intellectual Capital

Directory of Open Access Journals (Sweden)

Gholamreza Karami

2014-03-01

Full Text Available Intellectual capital (IC is one of the most valuable assets of firms, which has a significant role in success and wealth creation of the entities. Although these assets do not meet recognition criteria of accounting standards and are not reflected in financial statements, but they exist and the evidence indicates that they can affect managers, investors and other stakeholders’ decisions. It is expected that companies have incentives voluntarily report information about IC, due to the benefits thereof. Moreover because of the latest changes in the conceptual framework, we can expect acceleration in the movement towards recognition, measurement and disclosure of IC. In this article first we present the definition and the most important elements of IC, and then different ways of measuring this asset in accounting will be discussed. In rest of the paper incentives for disclosing IC will be presented, in order that the attention of the standard setters is attracted to the latest developments in this field and also the attention of investors becomes focused on this important asset of companies.

Disclosing a disability: Do strategy type and onset controllability make a difference?

Science.gov (United States)

Lyons, Brent J; Volpone, Sabrina D; Wessel, Jennifer L; Alonso, Natalya M

2017-09-01

In hiring contexts, individuals with concealable disabilities make decisions about how they should disclose their disability to overcome observers' biases. Previous research has investigated the effectiveness of binary disclosure decisions-that is, to disclose or conceal a disability-but we know little about how, why, or under what conditions different types of disclosure strategies impact observers' hiring intentions. In this article, we examine disability onset controllability (i.e., whether the applicant is seen as responsible for their disability onset) as a boundary condition for how disclosure strategy type influences the affective reactions (i.e., pity, admiration) that underlie observers' hiring intentions. Across 2 experiments, we found that when applicants are seen as responsible for their disability, strategies that de-emphasize the disability (rather than embrace it) lower observers' hiring intentions by elevating their pity reactions. Thus, the effectiveness of different types of disability disclosure strategies differs as a function of onset controllability. We discuss implications for theory and practice for individuals with disabilities and organizations. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Full Text Available The aim of this study was to evaluate the effectiveness of cleaning procedures for air-abraded zirconia after contamination with two silicone disclosing agents. Air-abraded zirconia ceramic specimens (IPS e.max ZirCAD were contaminated with either GC Fit Checker white or GC Fit Checker II. Untreated zirconia specimens were used as control. Afterwards the surfaces were cleaned either with waterspray or ultrasonically in 99% isopropanol or using a newly developed cleaning paste (Ivoclean. After cleaning X-ray photoelectron spectroscopy (XPS was performed and the relative peak intensities of Zr, C and Si were used for a qualitative comparison of the residuals. There was no significant difference between the two different silicone disclosing agents. An additional cleaning step with isopropanol led to a significantly lower amount of residuals on the surface, but an additional cleaning process with Ivoclean did not reduce the amount of carbon residuals in comparison to the isopropanol cleaning. Just the silicone amount on the surface was reduced. None of the investigated cleaning processes removed all residuals from the contaminated surface. Standard cleaning processes do not remove all residuals of the silicone disclosing agent from the surface. This may lead to a failure of the resin-ceramic bonding.

Quantitative research investigating the effects of general practitioner communication on a patient's comfort to disclose intimate partner violence is lacking. We explored the association between GPs' communication and patients' comfort to discuss fear of an intimate partner. A health/lifestyle survey mailed to 14 031 women (aged 16-50 years) who attended the participating GPs of 40 Victorian general practices during the previous year. There was a 32% response rate (n=4467). The results showed that female GPs were perceived as having better communication; an association between female GPs and comfort to disclose was not apparent in multivariate analyses. Time, caring, involving the patient in decisions and putting the patient at ease maintained associations with comfort to discuss, as did language, lower education, age >25 years and current fear. This study advocates increasing communication competence to allow for greater disclosure of sensitive issues such as intimate partner violence in the primary care context. However, it also signals a need in research and practice to focus on marginalised groups and intimate partner violence.

Support Seeking or Familial Obligation: An Investigation of Motives for Disclosing Genetic Test Results.

Greenberg, Marisa; Smith, Rachel A

Genetic test results reveal not only personal information about a person's likelihood of certain medical conditions but also information about the person's genetic relatives. Given the familial nature of genetic information, one's obligation to protect family members may be a motive for disclosing genetic test results, but this claim has not been methodically tested. Existing models of disclosure decision making presume self-interested motives, such as seeking social support, instead of other-interested motives, like familial obligation. This study investigated young adults' (N = 173) motives to share a genetic-based health condition, alpha-1 antitrypsin deficiency, after reading a hypothetical vignette. Results show that social support and familial obligation were both reported as motives for disclosure. In fact, some participants reported familial obligation as their primary motivator for disclosure. Finally, stronger familial obligation predicted increased likelihood of disclosing hypothetical genetic test results. Implications of these results were discussed in reference to theories of disclosure decision-making models and the practice of genetic disclosures.

Background The effects of disclosing financial interests to potential research participants are not well understood. Objective To examine the effects of financial interest disclosures on potential research participants’ attitudes toward clinical research. Design and Participants Computerized experiment conducted with 3,623 adults in the United States with either diabetes mellitus or asthma, grouped by lesser and greater severity. Respondents read a description of a hypothetical clinical trial relevant to their diagnosis that included a financial disclosure statement. Respondents received 1 of 5 disclosure statements. Measurements Willingness to participate in the hypothetical clinical trial, relative importance of information about the financial interest, change in trust after reading the disclosure statement, surprise regarding the financial interest, and perceived effect of the financial interest on the quality of the clinical trial. Results Willingness to participate in the hypothetical clinical trial did not differ substantially among the types of financial disclosures. Respondents viewed the disclosed information as less important than other factors in deciding to participate. Disclosures were associated with some respondents trusting the researchers less, although trust among some respondents increased. Most respondents were not surprised to learn of financial interests. Researchers owning equity were viewed as more troubling than researchers who were compensated for the costs of research through per capita payments. Conclusions Aside from a researcher holding an equity interest, the disclosure to potential research participants of financial interests in research, as recommended in recent policies, is unlikely to affect willingness to participate in research.

Current Alzheimer's disease (AD) research initiatives focus on cognitively healthy individuals with biomarkers that are associated with the development of AD. It is unclear whether biomarker results should be returned to research participants and what the psychological, behavioral and social effects of disclosure are. This systematic review therefore examines the psychological, behavioral and social effects of disclosing genetic and nongenetic AD-related biomarkers to cognitively healthy research participants. We performed a systematic literature search in eight scientific databases. Three independent reviewers screened the identified records and selected relevant articles. Results extracted from the included articles were aggregated and presented per effect group. Fourteen studies met the inclusion criteria and were included in the data synthesis. None of the identified studies examined the effects of disclosing nongenetic biomarkers. All studies but one concerned the disclosure of APOE genotype and were conducted in the USA. Study populations consisted largely of cognitively healthy first-degree relatives of AD patients. In this group, disclosure of an increased risk was not associated with anxiety, depression or changes in perceived risk in relation to family history. Disclosure of an increased risk did lead to an increase in specific test-related distress levels, health-related behavior changes and long-term care insurance uptake and possibly diminished memory functioning. In cognitively healthy research participants with a first-degree relative with AD, disclosure of APOE ε4-positivity does not lead to elevated anxiety and depression levels, but does increase test-related distress and results in behavior changes concerning insurance and health. We did not find studies reporting the effects of disclosing nongenetic biomarkers and only one study included people without a family history of AD.

Indocyanine green videoangiography (IGV) has proven its effectiveness in the field of exovascular neurosurgery, both in the intracranial and spinal compartment, but is necessary to define a systematic process for the performance of the IGV to facilitate its interpretation during the procedure. We have defined and applied the concept of videoangiography "in negative" (INIGV) to spinal dural arteriovenous fistulae (dAVF) for the detection and treatment of arteriovenous shunts, so called because the first phase is performed with the vessel suggestive of being pathological occluded. A Pentero-operating microscope with near-infrared IGV-integrated system (Carl Zeiss Co., Germany) was used. At our institution, 24 patients were treated for a spinal dAVF between 1995 and 2011, only in the last 4 cases, INIGV was performed. We describe the IGV in negative procedure and show the most illustrative cases. In all cases, the fistula occlusion was confirmed by postoperative selective digital subtraction angiography (DSA). INIGV demonstrate its capacity in detecting vessels not actually arterialized that should be respected and avoid some of the main limitations of the conventional IGV. This is a technical description about an Indocyanine green (ICG) videoangiographic procedure modification that is superior to merely performing ICG before and after clipping of a dAVF. The INIGV results are rapid and easy to interpret procedure and provide great advantages to the dAVF treatment. Nevertheless, further studies are needed with a larger sample size to determine if INIGV may reduce the need to perform immediate postoperative DSA.

We report the characteristics, diagnosis and treatment of dural arteriovenous fistula (DAVF) of the hypoglossal canal in nine patients with this relatively rare vascular disorder. Of 248 patients with intracranial DAVFs managed at our institution, nine patients (3.6%; four men, five women; mean age 62 years) were diagnosed with hypoglossal canal DAVF. We investigated patient characteristics with respect to clinical symptoms, neuroradiological findings, efficacy and complications related to endovascular treatment. Seven patients had experienced head injury. All patients presented with pulsatile tinnitus. One patient displayed ipsilateral hypoglossal nerve palsy before treatment. MR angiography showed a 'magic wand' appearance between the affected hypoglossal canal and the internal jugular vein in four patients. Angiography demonstrated an AV fistula on the medial aspect of the superior jugular bulb, mostly arising from the bilateral occipital, ascending pharyngeal and vertebral arteries with drainage to the internal jugular vein via the anterior condylar vein. Contralateral carotid injection accurately clarified the shunting point. Five patients underwent endovascular treatment: transarterial embolization (TAE; n=2), transvenous embolization (TVE; n=2), and TAE/TVE (n=1). Complete shunt obliteration was achieved in four patients and shunt reduction in one. The remaining four patients were treated conservatively and the shunt had disappeared at follow-up. Postoperative hypoglossal nerve palsy occurred in one patient after TVE, possibly due to coil overpacking. The incidence of hypoglossal canal DAVF was not very low in our series. Contralateral carotid injection is an essential examination to provide an accurate diagnosis. TVE should be considered when access is available, although TAE is also appropriate for shunt reduction.

Columnar joints form by cracking during cooling-induced contraction of lava, allowing hydrothermal fluid circulation. A lack of direct observations of their formation has led to ambiguity about the temperature window of jointing and its impact on fluid flow. Here we develop a novel thermo-mechanical experiment to disclose the temperature of columnar jointing in lavas. Using basalts from Eyjafjallajökull volcano (Iceland) we show that contraction during cooling induces stress build-up below the solidus temperature (980 °C), resulting in localised macroscopic failure between 890 and 840 °C. This temperature window for incipient columnar jointing is supported by modelling informed by mechanical testing and thermal expansivity measurements. We demonstrate that columnar jointing takes place well within the solid state of volcanic rocks, and is followed by a nonlinear increase in system permeability of <9 orders of magnitude during cooling. Columnar jointing may promote advective cooling in magmatic-hydrothermal environments and fluid loss during geothermal drilling and thermal stimulation.

The right to know and the duty to disclose hazard information.

Baram, M S

1984-04-01

In late 1983, the Occupational Safety and Health Administration (OSHA) promulgated its final rule on "hazard communication," establishing the right of workers in manufacturing industries to information about chemical hazards, and the duty of importers and manufacturers to disclose such information. Baram reviews areas where the new, limited OSHA regulation conflicts with existing local, state, and federal laws, many of which are more stringent and more protective of worker and community health. He suggests steps that could be taken to avoid the extensive litigation that might result from the potential preemptive effect of the new OSHA rule.

Timing, severity of deficits, and clinical improvement after surgery for spinal dural arteriovenous fistulas.

Science.gov (United States)

Safaee, Michael M; Clark, Aaron J; Burkhardt, Jan-Karl; Winkler, Ethan A; Lawton, Michael T

2018-04-20

OBJECTIVE Spinal dural arteriovenous fistulas (dAVFs) are rare vascular abnormalities caused by arteriovenous shunting. They often form at the dural root sleeve between a radicular feeding artery and draining medullary vein causing venous congestion and edema, decreased perfusion, and ischemia of the spinal cord. Treatment consists of either surgical ligation of the draining vein or selective embolization via an endovascular approach. There is a paucity of data on which modality provides more durable and effective outcomes. METHODS The authors performed a retrospective review of a prospectively maintained database by the senior author to assess clinical outcomes in patients undergoing surgical treatment of spinal dAVFs. Preoperative and postoperative motor and Aminoff-Logue Scale (ALS) scores were collected. RESULTS A total of 41 patients with 44 spinal dAVFs were identified, with a mean patient age of 64 years. The mean symptom duration was 14 months, with weakness (82%), urinary symptoms (47%), and sensory symptoms (29%) at presentation. The fistula locations were as follows: 30 thoracic, 9 lumbar, 3 sacral, and 2 cervical. Five patients had normal motor and ALS scores at presentation. Among the remaining 36 patients with motor deficits or abnormal gait and micturition at presentation, 78% experienced an improvement while the remaining 22% continued to be stable. There was a trend toward improved outcomes in patients with shorter symptom duration; mean symptom duration among patients with clinical improvement was 13 months compared with 22 months among those without improvement. Additionally, rates of improvement were higher for lower thoracic and lumbosacral dAVFs (85% and 83%) compared with those in the upper thoracic spine (57%). No patient developed recurrent fistulas or worsening neurological deficits. CONCLUSIONS Surgery is associated with excellent outcomes in the treatment of spinal dAVFs. Early diagnosis and treatment are critical, with a trend toward

The requirements of the health policy and services journals for authors to report their financial and non-financial conflicts of interest (COI) are unclear. The present article aims to assess the requirements of health policy and services journals for authors to disclose their financial and non-financial COIs. This is a cross-sectional study of journals listed by the Web of Science under the category of 'Health Policy and Services'. We reviewed the 'Instructions for Authors' on the journals' websites and then simulated the submission of a manuscript to obtain any additional relevant information made available during that step. We abstracted data in duplicate and independently using a standardised form. Out of 72 eligible journals, 67 (93%) had a COI policy. A minority of policies described how the disclosed COIs of authors would impact the editorial process (34%). None of the policies had clear-cut criteria for rejection based on the content of the disclosure. Approximately a fifth of policies (21%) explicitly stated that inaccurate or incomplete disclosures might lead to manuscript rejection or retraction. No policy described whether the journal would verify the accuracy or completeness of authors' disclosed COIs. Most journals' policies (93%) required the disclosure of at least one form of financial COI. While the majority asked for specification of source of payment (71%), a minority asked for the amount (18%). Overall, 81% of policies explicitly required disclosure of non-financial COIs. A majority of health policy and services journal policies required the disclosure of authors' financial and non-financial COIs, but few required details on disclosed COIs. Health policy journals should provide specific definitions and instructions for disclosing non-financial COIs. A framework providing clear typology and operational definitions of the different types of COIs will facilitate both their disclosure by authors and reviewers and their assessment and management by

2016-07-01

Researchers' obligations to disclose genetic incidental findings (GIFs) have been widely debated, but there has been little empirical study of the engagement of institutional review boards (IRBs) with this issue. This article presents data from the first extensive (n = 796) national survey of IRB professionals' understanding of, experience with, and beliefs surrounding GIFs. Most respondents had dealt with questions about GIFs (74%), but only a minority (47%) felt prepared to address them. Although a majority believed that there is an obligation to disclose GIFs (78%), there is still not consensus about the supporting ethical principles. Respondents generally did not endorse the idea that researchers' additional time and effort (7%), and lack of resources (29%), were valid reasons for diminishing a putative obligation. Most (96%) supported a right not to know, but this view became less pronounced (63%) when framed in terms of specific case studies. IRBs are actively engaged with GIFs but have not yet reached consensus. Respondents were uncomfortable with arguments that could be used to limit an obligation to return GIFs. This could indicate that IRBs are providing some of the impetus for the trend toward returning GIFs, although questions remain about the relative contribution of other stakeholders.Genet Med 18 7, 705-711.

A 63-year-old man developed vomiting, paraparesis, dysuria, bulbar palsy, and orthostatic hypotension over a period of 5 months. Neuroradiological examinations showed a swollen lower brainstem with a dural arteriovenous fistula at the craniocervical junction (DAVF-CCJ). A steroid was administered intravenously in the hospital to relieve brainstem edema. A few hours later, however, the patient developed acute tetraparesis with respiratory failure. Recently, there have been several reports describing the acute worsening of paraparesis in patients with a spinal dural arteriovenous fistula after steroid treatment. In addition to these reports, the present case suggests the risk of administering steroids to patients with DAVF-CCJ, especially those with brainstem dysfunction. PMID:29225249

Cash flows are incrementally useful to earnings in security valuation mainly when earnings quality is low. This suggests that when earnings quality decreases, analysts will be more likely to supplement their earnings forecasts with cash flow estimates. Contrary to this prediction, we find that analysts do not disclose cash flow forecasts when the quality of earnings is low. This is because cash flow forecast accuracy depends on the accuracy of the accrual estimates and the precision of accrua...

Doctors' duty to disclose error: a deontological or Kantian ethical analysis.

Science.gov (United States)

Bernstein, Mark; Brown, Barry

2004-05-01

Medical (surgical) error is being talked about more openly and besides being the subject of retrospective reviews, is now the subject of prospective research. Disclosure of error has been a difficult issue because of fear of embarrassment for doctors in the eyes of their peers, and fear of punitive action by patients, consisting of medicolegal action and/or complaints to doctors' governing bodies. This paper examines physicians' and surgeons' duty to disclose error, from an ethical standpoint; specifically by applying the moral philosophical theory espoused by Immanuel Kant (ie. deontology). The purpose of this discourse is to apply moral philosophical analysis to a delicate but important issue which will be a matter all physicians and surgeons will have to confront, probably numerous times, in their professional careers.

Reconstructive treatment of dural arteriovenous fistulas of the transverse and sigmoid sinus: transvenous angioplasty and stent deployment

International Nuclear Information System (INIS)

Liebig, T.; Henkes, H.; Brew, S.; Miloslavski, E.; Kuehne, D.; Kirsch, M.

2005-01-01

Various techniques for the endovascular treatment of dural arteriovenous fistulas (dAVFs) of the transverse and sigmoid sinus have recently evolved. Transvenous coil occlusion of the involved segment and transarterial embolization of the feeding arteries with liquid agents are the commonest treatments utilized. However, with respect to venous hypertension as the probable pathogenic cause of this disorder, a nonocclusive or remodeling technique might be preferable. We will present a series involving four patients, treated with transvenous angioplasty and stent deployment as a definitive treatment of dAVFs of the transverse and sigmoid sinus. This method was used as a primary treatment or as an adjunct to previous noncurative transarterial n-butyl cyanoacrylate and particle embolization. In three of the four cases, complete occlusion of the fistula was achieved with confirmation of occlusion seen on follow-up angiographical studies. In one case a negligible and nonsymptomatic remnant of the fistula fed by the tentorial artery was left untreated. From our experience, we conclude that transvenous stent deployment is an alternative to traditional concepts. Additionally, the pathological theory of dAVFs in this region located in venous pouches of the sinus wall is supported by the fact that they can be occluded by mechanical compression during angioplasty and subsequently maintained by a stent.

How could disclosing incidental information from whole-genome sequencing affect patient behavior?

Science.gov (United States)

Christensen, Kurt D; Green, Robert C

2013-06-01

In this article, we argue that disclosure of incidental findings from whole-genome sequencing has the potential to motivate individuals to change health behaviors through psychological mechanisms that differ from typical risk assessment interventions. Their ability to do so, however, is likely to be highly contingent upon the nature of the incidental findings and how they are disclosed, the context of the disclosure and the characteristics of the patient. Moreover, clinicians need to be aware that behavioral responses may occur in unanticipated ways. This article argues for commentators and policy makers to take a cautious but optimistic perspective while empirical evidence is collected through ongoing research involving whole-genome sequencing and the disclosure of incidental information.

"How Do We Start? And How Will They React?" Disclosing to Young People with Perinatally Acquired HIV in Uganda.

Science.gov (United States)

Namukwaya, Stella; Paparini, Sara; Seeley, Janet; Bernays, Sarah

2017-01-01

Despite great advances in pediatric HIV care, rates and the extent of full disclosure of HIV status to infected children remain low especially in resource-constrained setting. The World Health Organisation recommends that, by the age of 10-12 years old, children should be made fully aware of their HIV-positive status. However, this awareness is often delayed until much later in their adolescence. Few studies have been conducted to investigate what influences caregivers' decision-making process in this regard in low-income settings. In this article, we present an analysis of care dyads of caregivers and HIV-positive young people in Kampala, Uganda, as part of the findings of a longitudinal qualitative study about young people's adherence to antiretroviral therapy embedded in an international clinical trial (BREATHER). Repeat in-depth interviews were conducted with 26 young people living with HIV throughout the course of the trial, and once-off interviews with 16 of their caregivers were also carried out toward the end of the trial. In this article, we examine why and how caregivers decide to disclose a young person's HIV status to them and explore their feelings and dilemmas toward disclosure, as well as how young people reacted and the influence it had on their relationships with and attitudes toward their caregivers. Caregivers feared the consequences of disclosing the young person's positive status to them and disclosure commonly occurred hurriedly in response to a crisis, rather than as part of an anticipated and planned process. A key impediment to disclosure was that caregivers feared that disclosing would damage their relationships with the young people and commonly used this as a reason to continue to postpone disclosure. However, young people did not report prolonged feelings of blame or anger toward their caregivers about their own infection, but they did express frustration at the delay and obfuscation surrounding the disclosure process.

In PDT, once the photosensitizer is irradiated with light of a specific wavelength, it transfers the excitation energy to molecular oxygen, which gives rise to singlet oxygen. METHODOLOGY/PRINCIPAL FINDINGS: Since plaque disclosing agents usually contain photosensitizers such as rose bengal, erythrosine, and phloxine, they could be used for PTD upon photoactivation. The aim of the present study is to compare the ability of these three photosensitizers to produce singlet oxygen in relation to their bactericidal activity. The generation rates of singlet oxygen determined by applying an electron spin resonance technique were in the order phloxine > erythrosine ≒ rose bengal. On the other hand, rose bengal showed the highest bactericidal activity against Streptococcus mutans, a major causative pathogen of caries, followed by erythrosine and phloxine, both of which showed activity similar to each other. One of the reasons for the discrepancy between the singlet oxygen generating ability and bactericidal activity was the incorporation efficiency of the photosensitizers into the bacterial cells. The incorporation rate of rose bengal was the highest among the three photosensitizers examined in the present study, likely leading to the highest bactericidal activity. Meanwhile, the addition of L-histidine, a singlet oxygen quencher, cancelled the bactericidal activity of any of the three photoactivated photosensitizers, proving that singlet oxygen was responsible for the bactericidal action. CONCLUSIONS: It is strongly suggested that rose bengal is a suitable photosensitizer for the plaque disclosing agents as compared to the other two photosensitizers, phloxine and erythrosine, when used for PDT.

For survivors of childhood sexual abuse (CSA), verbal disclosure is often complex and painful. The authors examined the voluntary disclosure-nondisclosure of CSA in relation to nonverbal expressions of emotion in the face. Consistent with hypotheses derived from recent theorizing about the moral nature of emotion, CSA survivors who did not voluntarily disclose CSA showed greater facial expressions of shame, whereas CSA survivors who voluntarily disclosed CSA expressed greater disgust. Expressions of disgust also signaled sexual abuse accompanied by violence. Consistent with recent theorizing about smiling behavior, CSA nondisclosers made more polite smiles, whereas nonabused participants expressed greater genuine positive emotion. Discussion addressed the implications of these findings for the study of disclosure of traumatic events, facial expression, and the links between morality and emotion.

This study aimed to evaluate the safety and efficiency of the endovascular treatment of transverse-sigmoid sinus dural arteriovenous fistulas (TS{sub d}AVF). A total of 150 consecutive patients and 348 procedures were evaluated. Pulsatile tinnitus (81%), headache (15%), and intracranial hemorrhage (10%) were the most frequent manifestations of the TS{sub d}AVFs. More than half of the affected sinuses were partially or completely thrombosed. Access-wise treatment was performed transarterial (n = 33), transvenous (n = 21), or a combination thereof (n = 96). A mean of 2.4 procedures per patient was required. Immediate postprocedural occlusion rate after transarterial embolization was 30% only. Transvenous treatment alone resulted in an early occlusion rate of 81%, with delayed complete obliteration of half of the remaining fistulas. After combined transarterial/transvenous treatment, the angiographic cure rate was 54%. At follow-up, 88% of patients with residual shunt after the treatment showed complete occlusion. The cumulative complication rate was 9% (n = 13), with minor adverse events in ten patients (7%) and major complications in three patients (2%). Transvenous coil occlusion of the sinus segment with the adjacent dAVF site, eventually combined with transarterial occlusion of supplying arteries, is a very effective and well-tolerated treatment method. In selected patients, variations of these methods (e.g., sinus stenting, compartmental sinus occlusion) can be useful. (orig.)

Many approaches to the anterior skull base have been reported. Frequently used are the pterional, the unilateral or bilateral frontobasal, the supraorbital and the frontolateral approach. Recently, endoscopic transnasal approaches have become more popular. The benefits of each approach has to be weighted against its complications and limitations. The aim of this study was to investigate if the anterior interhemispheric approach (AIA) could be a safe and effective alternative approach to tumorous and non-tumorous lesions of the anterior skull base. We screened the operative records of all patients with an anterior skull base lesion undergoing transcranial surgery. We have used the AIA in 61 patients. These were exclusively patients with either olfactory groove meningioma (OGM) (n = 43), ethmoidal dural arteriovenous fistula (dAVF) ( n = 6) or frontobasal fractures of the anterior midline with cerebrospinal fluid (CSF) leakage ( n = 12). Patient records were evaluated concerning accessibility of the lesion, realization of surgical aims (complete tumor removal, dAVF obliteration, closure of the dural tear), and approach related complications. The use of the AIA exclusively in OGMs, ethmoidal dAVFs and midline frontobasal fractures indicated that we considered lateralized frontobasal lesions not suitable to be treated successfully. If restricted to these three pathologies, the AIA is highly effective and safe. The surgical aim (complete tumor removal, complete dAVF occlusion, no rhinorrhea) was achieved in all patients. The complication rate was 11.5 % (wound infection (n = 2; 3.2 %), contusion of the genu of the corpus callosum, subdural hygroma, epileptic seizure, anosmia and asymptomatic bleed into the tumor cavity (n = 1 each). Only the contusion of the corpus callosum was directly related to the approach (1.6 %). Olfaction, if present before surgery, was preserved in all patients, except one (1.6 %). The AIA is an effective and a safe approach

Background Although general recommendations for diagnostic disclosure of dementia are available, little is known about how these recommendations are implemented. The aim of the current study was to investigate the process and content of dementia diagnostic disclosure meetings, and to compare key aspects of disclosing a diagnosis of dementia and mild cognitive impairment. Method A total of 54 specialist physicians in Danish dementia diagnostic departments completed an online survey on their practices regarding diagnostic disclosure of dementia and mild cognitive impairment. The influence of respondent characteristics was assessed, and differences on key aspects of disclosing a diagnosis of dementia and mild cognitive impairment were analyzed. Results The results suggest that among Danish specialist physicians, there is a general consensus regarding the organization of diagnostic disclosure meetings. However, differences in employed terminology and information provided when disclosing a dementia diagnosis were evident. Significant differences were present on key aspects of the diagnostic disclosure of dementia and mild cognitive impairment. For instance, 91% would use the term dementia during diagnostic disclosures compared to just 72% for mild cognitive impairment. Conclusion The range of practices reflected in the present study confirms the complexity of diagnostic disclosure and highlights the importance of preparation and follow-up strategies to tailor the disclosure process to the needs of individual patients with dementia and their caregivers. Due to earlier diagnosis of neurodegenerative disorders, more research is urgently needed on this aspect of the diagnostic process, especially to develop evidence-based models for the disclosure of mild cognitive impairment.

To explore in detail how women perceived their experience of domestic violence and leaving or ending the abuse. This research also examined how service providers identified their professional role in assisting women to end such relationships. Domestic violence against women continues to occur internationally. Reliable statistics are difficult to capture because of inconsistent definitions, contradictory methods of acquiring data and unreported incidents. A qualitative study, undertaken in two phases, was conducted in Australia. Twelve women who had experienced domestic violence and ended those relationships participated in one semistructured interview (Phase 1). Twenty-five professionals from health, social sciences and law, whose work included assisting women experiencing domestic violence, participated in three focus groups (Phase 2). Thematic analysis guided by a narrative inquiry approach forms the framework for information collection and interpretation of data in this project. The barriers that impede women from disclosing abuse and taking action to end domestic violence are complex and varied between participants. Women did not always acknowledge or realise their relationship was precarious and often denied or minimised the abuse to cope with the domestic violence. Professionals identified that women did not always identify or acknowledge abuse inherent in their relationship although this delayed the provision of appropriate services. Whether women disclose abuse or deny violence in their relationship, acceptance by service providers and the offer of support is crucial to assisting women in violent relationships. It is hoped that the findings may assist health practitioners, including nurses, to provide nonjudgemental support to women experiencing domestic violence whether women acknowledge the abusive relationship or not. © 2016 John Wiley & Sons Ltd.

Highlights: • The conventional neuroimaging manifestations of dural arteriovenous fistulas are highly variable. • Identification of cortical venous reflux is important to prevent complications. • Tortuous and dilated vessels without a nidus are associated with cortical venous reflux. • Digital subtraction angiography remains the gold standard for DAVF diagnosis. - Abstract: Purpose: To compare the conventional CT and MR findings of DAVFs in relation to the venous drainage pattern on digital subtraction angiography (DSA). Materials and Methods: Cross-sectional imaging findings (CT and/or MR) in 92 patients were compared to the presence of cortical venous reflux (CVR) on DSA. Results: Imaging features significantly more prevalent in patients with CVR included: abnormally dilated and tortuous leptomeningeal vessels (92% vs. 4%, p < 0.001) or medullary vessels (69% vs. 0%, p < 0.001), venous ectasias (45% vs. 0%, p < 0.001) and focal vasogenic edema (38% vs. 0%, p < 0.001). The following findings trended towards association but did not reach the p value established following Bonferroni correction: dilated external carotid artery branches (71% vs. 38%, p = 0.005), cluster of vessels surrounding dural venous sinus (50% vs. 19%, p = 0.009), presence of hemorrhage (33 vs. 12%, p = 0.040), and parenchymal enhancement (21% vs. 0%, p = 0.030). Conclusion: In the appropriate clinical setting, recognition of ancillary signs presumably related to venous arterialization and congestion as well as arterial feeder hypertrophy should prompt DSA confirmation to identify DAVFs associated with CVR.

Resolution of clinical symptoms after reopening of an occluded inferior petrosal sinus in a patient with a cavernous sinus dural arteriovenous fistula. A case report.

We describe a rare case with a cavernous sinus (CS) dural arteriovenous fistula (DAVF) in which the clinical symptoms disappeared after the patient underwent reopening of an occluded inferior petrosal sinus (IPS). A 66-year-old woman presented with increased intraocular pressure, chemosis, and proptosis on the left side. Angiography demonstrated a left CS DAVF supplied by the dural branches of bilateral internal carotid arteries. The shunt flow was directed to the superior and inferior ophthalmic veins, while the bilateral IPSs were not opacified. Accordingly, a transvenous embolization of the fistula was attempted. Although the microcatheter was navigated to the cavernous sinus through the occluded left IPS, obliteration of the fistula was unsuccessful because of the failure of superselective catheterization at the fistulous point. However, the final image demonstrated the development of an antegrade shunt flow through the left IPS to the internal jugular vein and disappearance of the retrograde reflux to the superior and inferior ophthalmic veins. The patient's clinical symptoms immediately resolved after the operation, and the symptoms have not recurred during a one-year follow-up period. Inappropriate transvenous embolization of CS DAVFs can result in vascular complications arising from the unintentional redistribution of shunt flow. The present case illustrates that the disappearance of retrograde shunt flow to the ophthalmic veins after reopening of the occluded IPS may be sufficient if a superselective approach fails or is anticipated to result only in an incomplete embolization of the fistulous point.

“How Do We Start? And How Will They React?” Disclosing to Young People with Perinatally Acquired HIV in Uganda

Full Text Available Despite great advances in pediatric HIV care, rates and the extent of full disclosure of HIV status to infected children remain low especially in resource-constrained setting. The World Health Organisation recommends that, by the age of 10–12 years old, children should be made fully aware of their HIV-positive status. However, this awareness is often delayed until much later in their adolescence. Few studies have been conducted to investigate what influences caregivers’ decision-making process in this regard in low-income settings. In this article, we present an analysis of care dyads of caregivers and HIV-positive young people in Kampala, Uganda, as part of the findings of a longitudinal qualitative study about young people’s adherence to antiretroviral therapy embedded in an international clinical trial (BREATHER. Repeat in-depth interviews were conducted with 26 young people living with HIV throughout the course of the trial, and once-off interviews with 16 of their caregivers were also carried out toward the end of the trial. In this article, we examine why and how caregivers decide to disclose a young person’s HIV status to them and explore their feelings and dilemmas toward disclosure, as well as how young people reacted and the influence it had on their relationships with and attitudes toward their caregivers. Caregivers feared the consequences of disclosing the young person’s positive status to them and disclosure commonly occurred hurriedly in response to a crisis, rather than as part of an anticipated and planned process. A key impediment to disclosure was that caregivers feared that disclosing would damage their relationships with the young people and commonly used this as a reason to continue to postpone disclosure. However, young people did not report prolonged feelings of blame or anger toward their caregivers about their own infection, but they did express frustration at the delay and obfuscation surrounding the

Background and Objectives: One of the most important and complicated problems in medical ethics is to disclose the full truth about diagnosis of incurable diseases which leads to death, and each therapist may be encountered with it during the years of medical profession.

The aim of this study was to survey on attitude of professors and residents of clinical wards to disclose the diagnosis for incurable patients leading to death.

Methods: In this descriptive study, sampling was carried out by a survey. All faculty members and their residents of teaching hospitals of Urmia University of Medical Sciences, Urmia, Iran, were surveyed as sample in 2007. Of 145 subjects, 138 responded to the questionnaire. The collected data were analyzed using Pearson and Spearman correlation tests with a p≤0.05 being considered as significant.

Results: In this study, the tendency to disclose the diagnosis among faculty members and residents was 64.63%. Also, there was no significant relation between age, sex, university degree, educational field, years of service of the faculty members and residents of clinical wards with the tendency for telling the truth to incurable patients.

Conclusion: Final analyses revealed that the faculty members and clinical residents of different fields in terms of diagnosis disclosure do not have a definite idea. However, the majority of them agree to disclose the full truth about diagnoses.

How does disclosing countertransference affect perceptions of the therapist and the session?

Science.gov (United States)

Yeh, Yun-Jy; Hayes, Jeffrey A

2011-12-01

Therapist self-disclosure has been theorized and found to have both positive and negative effects. These effects depend, in part, on the nature of the disclosure. This study sought to examine the differential effects of therapist disclosures of more and less resolved countertransference issues on perceptions of therapists and therapy sessions. Using an analogue method, undergraduate participants (N = 116) were randomly assigned to watch one of two videos in which a therapist disclosed personal issues that were relatively resolved or relatively unresolved. As hypothesized, therapist disclosure of issues that were more resolved caused the therapist to be rated as more attractive and trustworthy and instilled greater hope than therapist disclosure of less resolved issues. The type of therapist disclosure, however, did not affect ratings of the expertness of the therapist, the depth or smoothness of the session, or the perceived universality between client and therapist. Implications of the results for the judicious use of self-disclosure are discussed.

Introduction This work reports the first indocyanine green videoangiography (IGV) in negative published with video format support. This technique, so called because its first phase is performed with occlusion of the vessel suspected of being pathologic, is used for the diagnosis of spinal arteriovenous fistula (sDAVF). Case Report The authors present the case of a 68-year-old man with an sDAVF fed by the right T7 segmentary artery. IGV was initially performed with the presumptive fistula feeder occluded for less than 1 minute, which provided both diagnostic and postexclusion control in one procedure. This technique therefore is reversible by not prolonging vascular exclusion times. Discussion IGV in negative is an extremely visual and intuitive procedure that represents an improvement over conventional IGV. Conclusion Studies with larger sample sizes are necessary to determine whether IGV in negative can further reduce the need for postoperative digital subtraction angiography.

Full Text Available The notons and motvatons of inter-organisatonal rivalries among employees have to some extent been highlighted by classical theories of management such as tournament theory. However, employees’ and entrepreneurs’ compettons are fundamentally different in patern. Based on the doctrine of entrepreneurship, entrepreneurial compettons are essental for a productve economy. Even so, there have been few in-depth holistc atempts to understand the rivalry process among corporate entrepreneurs. During the last three decades, various fragmented studies have been conducted from different standpoints to clarify the process of corporate entrepreneurship (CE. Nevertheless, considerable room remains for developing a model of the rivalry process with respect to entrepreneurial actvites within large and complex organisatons. Hence, the main contributon of the research can be claimed as investgatng and formulatng the rivalry process. For this purpose, a systematc qualitatve grounded theory methodology (GTM was used. During a fve-month period, corporate entrepreneurs from one of the chief Iranian research insttutes were systematcally interviewed. Based on the research results, in additon to endorsing the existence of such a rivalry process among corporate entrepreneurs, the GTM model extends the literature of CE by examining the previously unaddressed part of the process, i.e., disclosing the corporate entrepreneurs’ implemented strategies, among other blocks of the theory.

Nuclear science: Information on DOE accelerators should be better disclosed in the budget

Energy Technology Data Exchange (ETDEWEB)

1986-01-01

GAO estimated the total cost of six of the Department of Energy's largest accelerator projects to be about $6.9 billion. DOE has identified only about $0.6 billion of these project-specific costs in the budget. This is because DOE's definition of a project relates only to construction, which excludes certain project-specific components and preconstruction research and development. In addition, DOE funds a project in stages over a number of years and does not, when the first stage is authorized, identify for the Congress the total cost of completing the project. DOE also does not fully disclose in its budget technical uncertainties associated with the performance of certain accelerator components because its internal operating procedures do not require such disclosure. This could result in cost overruns or increased operating costs.

2017-02-01

As heavy media users, adolescents are frequently exposed to embedded advertising formats such as brand placements. Because this may lead to unwitting persuasion, regulations prescribe disclosure of brand placements. This study aimed to increase our understanding of the effects of disclosing television brand placements and disclosure duration on adolescents' persuasion knowledge (i.e., recognition of brand placement as being advertising, understanding that brand placement has a persuasive intent and critical attitude toward brand placement) and brand responses (i.e., brand memory and brand attitude). To do so, an earlier study that was conducted among adults was replicated among adolescents aged 13-17 years (N = 221, 44 % female). The present study shows that brand placement disclosure had limited effects on adolescents' persuasion knowledge as it only affected adolescents' understanding of persuasive intent, did not mitigate persuasion, but did increase brand memory. These findings suggest that brand placement disclosure has fundamentally different effects on adolescents than on adults: the disclosures had less effects on activating persuasion knowledge and mitigating persuasion among adolescents than among adults. Implications for advertising disclosure regulation and consequences for advertisers are discussed.

This study presents the case of a 4-year-old healthy child admitted to the paediatric ward for suspected accidental intoxication due to ingestion of narcoleptic drugs (methylphenidate, sertraline and quetiapine), taken on a regular basis by his 8-year-old brother affected by Asperger syndrome.Intoxication can be objectively assessed by measurements of drugs and metabolites in biological matrices with short-term (blood and urine) or long-term (hair) detection windows. At the hospital, the child's blood and urine were analysed by immunoassay (confirmed by liquid chromatography-mass spectrometry), and sertraline and quetiapine and their metabolites were identified. The suspicion that the mother administered drugs chronically prompted the analysis of six, consecutive 2-cm segments of the child's hair, using ultra-high performance liquid chromatography-tandem mass spectrometry, thereby accounting for ingestion over the previous 12 months. Quetiapine was found in the first four segments with a mean concentration of 1.00 ng/mg ± 0.94 ng/mg hair while sertraline and its metabolite, desmethyl-sertraline, were found in all segments with a mean concentration of 2.65 ± 0.94 ng/mg and 1.50 ± 0.94 ng/mg hair, respectively. Hair analyses were negative for methylphenidate and its metabolite (ritalinic acid). Biological matrices testing for psychoactive drugs disclosed both acute and chronic intoxication with quetiapine and sertraline administered by the mother.

Full Text Available Dental plaque removal is an important issue in health promotion. Toothbrushing is one of the main methods employed for such purpose, since it can prevent dental caries by means of the fluoride present in the dentifrice. Dentifrices might contain plaque disclosing agents and thus allow dental plaque observation. The aim of this study was to assess whether utilization of a plaque disclosing agent interfered with plaque removal among adolescents, as well as the difference between utilization of erythrosine tablets and dentifrices containing plaque disclosing agent. The sample was composed of 62 students from Piracicaba, SP, Brazil, aged 12 to 14 years old, divided into 3 groups: G1 or control group (toothbrushing without plaque disclosure; G2 (plaque disclosing with an erythrosine tablet and toothbrushing and G3 (toothbrushing with dentifrice containing plaque disclosing agent. After toothbrushing, disclosure of the remaining dental plaque was performed in all groups with a fuchsin tablet and measured through the Simplified Oral Health Assessment Index (OHI-S, in two stages with a 2-month interval between them. The analysis of variance (ANOVA showed that there was no difference in the OHI-S index between the groups (p>0.05, however the G3 displayed a higher proportion of students with plaque reduction (23% than G2 (21%, besides the smallest difference in the mean remaining dental plaque. There was no difference between groups; however, it was suggested that the dentifrice with plaque disclosing agent had positive results in relation to the erythrosine tablet, even though the small sample size may have interfered with the results, indicating the need of complementary studies.Na promoção de saúde, a remoção da placa bacteriana é um fator importante e um dos métodos que incentivam sua remoção, é a escovação dentária, podendo-se prevenir a cárie dental através do íon flúor dos dentifrícios.

Johnstone, Megan-Jane; Kanitsaki, Olga

2006-03-01

Nurses globally are required and expected to report nursing errors. As is clearly demonstrated in the international literature, fulfilling this requirement is not, however, without risks. In this discussion paper, the notion of 'nursing error', the practical and moral importance of defining, distinguishing and disclosing nursing errors and how a distinct definition of 'nursing error' fits with the new 'system approach' to human-error management in health care are critiqued. Drawing on international literature and two key case exemplars from the USA and Australia, arguments are advanced to support the view that although it is 'right' for nurses to report nursing errors, it will be very difficult for them to do so unless a non-punitive approach to nursing-error management is adopted.

Many adult survivors of childhood abuse hide their victimization, avoiding disclosure that could identify perpetrators, end the abuse, and bring help to the victim. We surveyed 1,679 women undergraduates to understand disclosure of childhood sexual, physical, and emotional abuse, and, for the first time, witnessed domestic violence, which many consider to be emotionally abusive. A substantial minority of victims failed to ever disclose their sexual abuse (23%), physical abuse (34%), emotional abuse (20%), and witnessed domestic violence (29%). Overall, abuse-specific factors were better predictors of disclosure than individual-level characteristics. Disclosure of sexual abuse was related to experiencing more frequent abuse (by the same and by multiple perpetrators), being more worried about injury and more upset at the time of the abuse, and self-labeling as a victim of abuse. Disclosure of physical abuse was related to experiencing more frequent abuse (by the same and multiple perpetrators), being less emotionally close to the perpetrator, being older when the abuse ended, being more worried and upset, and self-labeling as a victim. Disclosure of emotional abuse was associated with being older when the abuse ended, and being more worried and upset. Disclosure was unrelated to victim demographic characteristics or defensive reactions (dissociative proneness, fantasy proneness, repressive coping style, and temporary forgetting), except that among physical and emotional abuse victims, repressors were less likely to disclose than non-repressors.

This study aims to determine the likelihood that rural nurses perceive a hypothetical medication error would be reported in their workplace. This employs cross-sectional survey using hypothetical error scenario with varying levels of harm. Clinical settings in rural Tasmania. Participants were 116 eligible surveys received from registered and enrolled nurses. Frequency of responses indicating the likelihood that severe, moderate and near miss (no harm) scenario would 'always' be reported or disclosed. Eighty per cent of nurses viewed a severe error would 'always' be reported, 64.8% a moderate error and 45.7% a near-miss error. In regards to disclosure, 54.7% felt this was 'always' likely to occur for a severe error, 44.8% for a moderate error and 26.4% for a near miss. Across all levels of severity, aged-care nurses were more likely than nurses in other settings to view error to 'always' be reported (ranging from 72-96%, P = 0.010 to 0.042,) and disclosed (68-88%, P = 0.000). Those in a management role were more likely to view error to 'always' be disclosed compared to those in a clinical role (50-77.3%, P = 0.008-0.024). Further research in rural clinical settings is needed to improve the understanding of error management and disclosure. © 2015 The Authors.

Bevan, Jennifer L; Cummings, Megan B; Kubiniec, Ashley; Mogannam, Megan; Price, Madison; Todd, Rachel

2015-01-01

This study examined an aspect of Facebook disclosure that has as yet gone unexplored: whether a user prefers to share information directly, for example, through status updates, or indirectly, via photos with no caption or relationship status changes without context or explanation. The focus was on the sharing of important positive and negative life events related to romantic relationships, health, and work/school in relation to likelihood of sharing this type of information on Facebook and general attitudes toward privacy. An online survey of 599 adult Facebook users found that when positive life events were shared, users preferred to do so indirectly, whereas negative life events were more likely to be disclosed directly. Privacy shared little association with how information was shared. Implications for understanding the finer nuances of how news is shared on Facebook are discussed.

This study aims to review the diagnostic performance of computed tomography (CT) and magnetic resonance imaging (MRI) in symptomatic dural arteriovenous fistula (DAVF). EMBASE, PubMed, and Cochrane Library were searched until April 2015 for studies which compared CT, MRI, or both with angiography for the detection of DAVF. The diagnostic performances of MRI and CT were indirectly compared using modality as a covariate in the analysis. Thirteen studies met our inclusion criteria. MRI had a sensitivity of 0.90 (95 % confidence interval (CI) = 0.83-0.94) and specificity of 0.94 (95 % CI = 0.90-0.96). CT had a sensitivity of 0.80 (95 % CI = 0.62-0.90) and specificity of 0.87 (95 % CI = 0.74-0.94). MRI showed better diagnostic performance than CT (p = 0.02). Contrast medium use and time-resolved MR angiography did not improve MRI diagnostic performance (p = 0.31 and 0.44, respectively). Both CT and MRI had good diagnostic performance. MRI was better than CT on the detection of symptomatic intracranial dural arteriovenous fistula in the indirect comparison. (orig.)

Evolution of the Theoretical Approaches to Disclosing the Economic Substance of Accumulation of Capital

Yemets Vadym V.

2016-05-01

Full Text Available The article proposes a classification for periods of evolution of theoretical approaches to disclosing the economic substance of accumulation of capital, taking into account the civilizational approach to the development of society. The author has proposed five stages in the evolution of theoretical approaches, which are closely related to the development of economy and stipulate dominance of a certain form of accumulation of capital. So, the first stage (time period B.C. – the 5th Century is referred to as Individual-social significance of accumulation of capital; the second stage (from the 6th century to the 16th century – Accumulation of monetary capitals; the third stage (from the mid-17th century until the end of the 18th century – Industrialproduction accumulation of capital; the fourth stage (from the mid-19th century until the 70s of the 20th century – Investment-oriented accumulation of capital; the fifth stage (from the 70s of the 20th century up to the current period – Globally-intensive accumulation of capital.

A Right to Disclose: LGBTQ Youth Representation in Data, Science, and Policy.

Science.gov (United States)

Snapp, Shannon D; Russell, Stephen T; Arredondo, Mariella; Skiba, Russell

2016-01-01

There has been growing attention to sexual orientation and gender identity (SOGI) in child and adolescent development, public discourse, and research. A strong tension is clear: The right for participation, and thus representation in data, science, and policy, is often understood as conflicting with the right for protection, that is, safety from disclosure of a marginalized orientation or identity. Both participation and protection rights are also closely tied to young people's rights to privacy (or lack thereof). We review recent scholarship on SOGI in developmental sciences in light of this tension. We focus on schooling as a salient developmental context for all youth, a place that is historically unsafe for lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) youth, and a context where researchers have identified gaps of knowledge as well as strategies for improvement. Our review focuses on the politics and processes of SOGI inclusion in education data collection efforts in the United States, an area where SOGI data collection is scarce in comparison to other systems of care, such as health. We suggest that one solution to the dilemma would be that youth have the right to disclose their SOGI information to whom and when they choose. We offer strategies on how to hold these tensions in balance and move toward SOGI-inclusive research and data collection so that LGBTQ youth can be represented in data, science, and policy. © 2016 Elsevier Inc.

Catona, Danielle; Greene, Kathryn; Magsamen-Conrad, Kate

2015-01-01

People living with HIV/AIDS must make decisions about how, where, when, what, and to whom to disclose their HIV status. This study explores their perceptions of benefits and drawbacks of various HIV disclosure strategies. The authors interviewed 53 people living with HIV/AIDS from a large AIDS service organization in a northeastern U.S. state and used a combination of deductive and inductive coding to analyze disclosure strategies and advantages and disadvantages of disclosure strategies. Deductive codes consisted of eight strategies subsumed under three broad categories: mode (face-to-face, non-face-to-face, and third-party disclosure), context (setting, bringing a companion, and planning a time), and content (practicing and incremental disclosure). Inductive coding identified benefits and drawbacks for enacting each specific disclosure strategy. The discussion focuses on theoretical explanations for the reasons for and against disclosure strategy enactment and the utility of these findings for practical interventions concerning HIV disclosure practices and decision making.

Improved distal distribution of n-butyl cyanoacrylate glue by simultaneous injection of dextrose 5% through the guiding catheter: technical note

International Nuclear Information System (INIS)

Moore, Carolyn; Murphy, Kieran; Gailloud, Philippe

2006-01-01

The use of n-butyl cyanoacrylate (NBCA) as an adhesive agent for embolization of high-flow intracranial and extracranial vascular lesions is well established. To be successful, the embolization of arteriovenous malformations and fistulas must achieve obliteration of the arteriovenous shunts themselves rather than simply occlude the feeders proximal to the lesion. However, the feeders cannot always be negotiated over their entire length. This is often the case with dural arteriovenous fistulas (DAVF), which are usually vascularized by long and intricate meningeal networks. In such situations, NBCA may not be able to reach the lesion itself, rendering the embolization ineffective. We present a new technique that improves distal distribution of NBCA glue. The technique described in this report consists of injecting dextrose 5% through the guiding catheter simultaneously with the superselective injection of NBCA glue into the targeted feeding branch. The technique is illustrated with three cases of posterior fossa DAVF. In the reported cases, flooding the territory of the targeted vessel with non-ionic dextrose 5% allowed deep progression of the glue by delaying contact with ionic substances. Excellent distribution of the NBCA glue reaching the site of the arteriovenous shunts was thus obtained despite suboptimal proximal microcatheter tip positions. (orig.)

Disclosing Sex Trading Histories to Providers: Barriers and Facilitators to Navigation of Social Services Among Women Impacted by Commercial Sexual Exploitation.

Science.gov (United States)

Gerassi, Lara; Edmond, Tonya E; Fabbre, Vanessa; Howard, Abby; Nichols, Andrea J

2017-12-01

Sex trafficking and commercial sexual exploitation (CSE) can lead to devastating health and mental health consequences for women, such as elevated rates of substance use, trauma, posttraumatic stress disorder, depression, sexually transmitted infections (STIs), and HIV. Consequently, engagement with services that address addiction, mental health, and housing, and provide general advocacy is critically important to women's increased safety, stabilization, and quality of life. The purpose of this study is to identify perceived barriers and facilitators to service access and engagement with social services among women involved in CSE. Drawing from a larger grounded theory study that partnered with an anti-trafficking coalition and a substance use treatment center for women, in-depth, semistructured interviews were conducted with 30 adult women who traded sex as adults and 20 service providers who come into contact with this population. Women engaging in services were sampled through maximum variation sampling ( n = 24) and women not engaged with services ( n = 6) were recruited through snowball sampling. Providers were recruited through purposive sampling through the coalition ( n = 10) and nominations sampling ( n = 10). Open and focused coding were conducted. Multiple enhancements to methodological and analytic rigor were taken, including collaboration with multiple key stakeholders, use of nonstigmatizing language, self-reflexivity processes, analytic memo-writing, and member checking. Findings suggest that women experienced judgment when disclosing sex trading in social service intakes, and individual and group sessions from providers and other women in the groups. Although some women saw disclosure as helpful in addressing the complex feelings stemming from sex trading, as well as the desire to help or relate to other women in similar situations, they also identified risk of harm and multiple barriers to disclosing during intake meetings and individual sessions

Two-Dimensional Cysteine and Cystine Cluster Networks on Au(111) Disclosed by Voltammetry and in Situ Scanning Tunneling Microscopy

Zhang, Jingdong; Chi, Qijin; Nielsen, Jens Ulrik

2000-01-01

Microscopic structures for molecular monolayers of L-cysteine and L-cystine assembled on Au(111) have been disclosed by employing electrochemistry and in situ scanning tunneling microscopy (STM). HighresolutionSTMimages show that the adlayers of both cyteine and cystine exhibit highly......-ordered networklike clusters with (3x3 6)R30° structure. By combining the surface coverage estimated from voltammetric data, each cluster is demonstrated to include six individual cysteine molecules or three cystine molecules. As a comparison, no cluster structure is observed for the 1-butanethiol adlayer prepared...... and examined under the same conditions as those for cysteine and cystine. This suggests that intermolecular and intramolecular hydrogen bonds among adsorbed cysteine or cystine molecules could be responsible for the origin of the cluster-network structures for the adlayers. Several models are proposed and used...

Ethical, Legal, and Clinical Considerations when Disclosing a High-Risk Syndrome for Psychosis.

Science.gov (United States)

Mittal, Vijay A; Dean, Derek J; Mittal, Jyoti; Saks, Elyn R

2015-10-01

There are complex considerations when planning to disclose an attenuated psychosis syndrome (APS) diagnosis. In this review, we evaluate ethical, legal, and clinical perspectives as well as caveats related to full, non- and partial disclosure strategies, discuss societal implications, and provide clinical suggestions. Each of the disclosure strategies is associated with benefits as well as costs/considerations. Full disclosure promotes autonomy, allows for the clearest psychoeducation about additional risk factors, helps to clarify and/or correct previous diagnoses/treatments, facilitates early intervention and bolsters communication between providers but there are important considerations involving heritability, comorbidity, culture, and stigma. Non-disclosure advances nonmaleficence by limiting stigma and stress (which may inadvertently exacerbate the condition), and confusion (related to the rapidly evolving diagnosis) in a sensitive developmental period but is complicated by varying patient preferences and the possibility that, as new treatments without adverse effects become available, the risk with false positives no longer justifies the accompanying loss of autonomy. Partial disclosure balances ethical considerations by focusing on symptoms instead of labels, but evidence that laypersons may interpret this information as a pseudo-diagnosis and that symptoms alone also contribute to stigma limits the efficacy of this approach. In addition, there are notable societal considerations relating to disclosure involving conservatorship, the reach of insurance companies, and discrimination. We advocate a hybrid approach to disclosure and recommend future research aimed at understanding the effects of stigma on clinical course and a renewed focus on those help-seeking cases that do not transition but remain clinically relevant. © 2015 John Wiley & Sons Ltd.

Spherical oligo-silicic acid SOSA disclosed as possible endogenous digitalis-like factor

Directory of Open Access Journals (Sweden)

Franz eKerek

2015-01-01

Full Text Available Na+/K+-ATPase is a membrane ion-transporter protein, specifically inhibited by digitalis glycosides used in cardiac-therapy. The existence in mammals of some endogenous digitalis-like factors (EDLF as presumed ATPase ligands is generally accepted. But the chemical structure of these factors remained elusive because no weighable amounts of pure EDLF have been isolated. Recent high resolution crystal structure data of Na+/K+-ATPase have located the hydrophobic binding pocket of the steroid glycoside ouabain. Our recently disclosed spherical oligo-silicic acids (SOSA fulfill the main criteria to be identified with the presumed EDL factor. SOSA was found as a very potent inhibitor of the Na+/K+-ATPase, Ca2+-ATPase, H+/K+-ATPase and of K-dp-ATPase, with IC50 values between 0.2-0.5µg/ml. These findings are even more astonishing while so far, neither mono silicic acid nor its poly-condensed derivatives have been remarked biologically active. With the diameter ϕ between 1 - 3nm, SOSA still belong to molecular species definitely smaller than silica nano-particles with ϕ >5nm. In SOSA molecules almost all Si-OH bonds are displayed on the external shell which facilitates the binding to hydrophilic ATPase domains. SOSA is stable for long-term in solution but is sensitive to freeze-drying which could explain the failure of countless attempts to isolate pure EDLF. There is a strong resemblance between SOSA and vanadates, the previously known general inhibitors of P-type ATPases. SOSA may be generated endogenously by spherical oligomerization of the mono-silicic acid ubiquitously present in animal cells and fluids. Based on the finding that the SOSA structure is sensitive to the concentration and nature of the cationic species a presumably archaic mechanism to regulate the activity of the ATPase pumps is proposed.

Understanding the hesitancy to disclose teen dating violence: Correlates of self-efficacy to deal with teen dating violence

Directory of Open Access Journals (Sweden)

2014-01-01

Full Text Available Dating violence (DV is now recognized as an important public health issue. Prevention and intervention programs are being implemented in school contexts. Such initiatives aim to raise awareness among potential victims and offenders as well as among peer bystanders and offer adequate interventions following disclosure. Yet, a major challenge remains as teenagers may not disclose their victimization or may not feel self-efficient to deal with DV if they witness such violence. As such, teen DV remains largely hidden. A representative sample of 8194 students (age 14-18 in the province of Quebec, Canada was used to explore teenagers’ self-efficacy to reach out for help or to help others in a situation of DV victimization and perpetration. Analyses are conducted to identify possible correlates of self-efficacy in terms of socio-demographic variable (sex, age and a history of child sexual abuse and dating victimization. Implications for preven­tion and support strategies are discussed.

Traditional Sex and Gender Stereotypes in the Relationships of Non-Disclosing Behaviorally Bisexual Men.

Science.gov (United States)

Siegel, Karolynn; Meunier, Étienne

2018-06-04

Traditional stereotypes about sex and gender present men as assertive, aggressive, sexually adventurous, and emotionally restrained, and women as docile, passive, sexually modest, and emotionally sensitive. Past research has shown that such stereotypes impose constraints on heterosexual relationships that decrease sexual satisfaction for men and women. This study examined the impact of traditional sex and gender stereotypes on a sample of 203 behaviorally bisexual men who were in a heterosexual relationship with a woman to whom they did not disclose their same-sex behaviors. Participants' descriptions of their partners reified several traditional stereotypes regarding men's and women's sexual dispositions (e.g., men are more sexually adventurous than women), role during sex (e.g., men should be dominant and women submissive), relationship desires (i.e., women prefer long-term intimate relationships and men prefer unattached sexual gratification), and emotional involvement (e.g., women are emotionally sensitive and men emotionally detached). These stereotypes shaped participants' sexual relations with women and men, which were widely conceived as acts of domination-submission. Perceiving women as more skilled for emotional intimacy and affection, most participants would only develop intimate relationships with them; however, some participants also perceived women as too emotionally sensitive and described men as better companions. Many participants were dissatisfied with these gender norms although they conformed to them, further supporting that traditional sex and gender stereotypes impose constraints on relationships that can limit authentic sexual expression and intimate satisfaction.

Male-Partnered Bisexual Women's Perceptions of Disclosing Sexual Orientation to Family Across the Transition to Parenthood: Intensifying Heteronormativity or Queering Family?

Science.gov (United States)

Goldberg, Abbie E; Allen, Katherine R; Ellawala, Themal; Ross, Lori E

2018-01-01

Drawing from queer and communication privacy management frameworks, this study examines the narratives of 22 bisexual, male-partnered women who were interviewed during the perinatal period and one year postnatally about their disclosures of sexual identity to family of origin. Most women rarely discussed their sexual identity with family; participants who had disclosed described such disclosures as provoking discomfort. Some women stated that their parental status seemed to invalidate the need to talk about their sexual history or identity with family, due its declining salience and increased concerns about judgment. This study reveals how partnership and parenthood statuses contribute to the intensification of heteronormative pressures in relation to family. Therapists should attend to the role of heteronormative values regarding partnering, family-building, and parenting. © 2017 American Association for Marriage and Family Therapy.

Clinical importance of the middle meningeal artery: A review of the literature.

Science.gov (United States)

Yu, Jinlu; Guo, Yunbao; Xu, Baofeng; Xu, Kan

2016-01-01

The middle meningeal artery (MMA) is a very important artery in neurosurgery. Many diseases, including dural arteriovenous fistula (DAVF), pseudoaneurysm, true aneurysm, traumatic arteriovenous fistula (AVF), moyamoya disease (MMD), recurrent chronic subdural hematoma (CSDH), migraine and meningioma, can involve the MMA. In these diseases, the lesions occur in either the MMA itself and treatment is necessary, or the MMA is used as the pathway to treat the lesions; therefore, the MMA is very important to the development and treatment of a variety of neurosurgical diseases. However, no systematic review describing the importance of MMA has been published. In this study, we used the PUBMED database to perform a review of the literature on the MMA to increase our understanding of its role in neurosurgery. After performing this review, we found that the MMA was commonly used to access DAVFs and meningiomas. Pseudoaneurysms and true aneurysms in the MMA can be effectively treated via endovascular or surgical removal. In MMD, the MMA plays a very important role in the development of collateral circulation and indirect revascularization. For recurrent CDSHs, after burr hole irrigation and drainage have failed, MMA embolization may be attempted. The MMA can also contribute to the occurrence and treatment of migraines. Because the ophthalmic artery can ectopically originate from the MMA, caution must be taken to avoid causing damage to the MMA during operations.

Assessment factors (AFs) are commonly used for deriving reference concentrations for chemicals. These factors take into account variabilities as well as uncertainties in the dataset, such as inter-species and intra-species variabilities or exposure duration extrapolation or extrapolation from the lowest-observed-adverse-effect level (LOAEL) to the noobserved- adverse-effect level (NOAEL). In a deterministic approach, the value of an AF is the result of a debate among experts and, often a conservative value is used as a default choice. A probabilistic framework to better take into account uncertainties and/or variability when setting occupational exposure limits (OELs) is presented and discussed in this paper. Each AF is considered as a random variable with a probabilistic distribution. A short literature was conducted before setting default distributions ranges and shapes for each AF commonly used. A random sampling, using Monte Carlo techniques, is then used for propagating the identified uncertainties and computing the final OEL distribution. Starting from the broad default distributions obtained, experts narrow it to its most likely range, according to the scientific knowledge available for a specific chemical. Introducing distribution rather than single deterministic values allows disclosing and clarifying variability and/or uncertainties inherent to the OEL construction process. This probabilistic approach yields quantitative insight into both the possible range and the relative likelihood of values for model outputs. It thereby provides a better support in decision-making and improves transparency. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

The increased use of PET amyloid imaging in clinical research has sparked numerous concerns about whether and how to return such research test results to study participants. Chief among these is the question of how best to disclose amyloid imaging research results to individuals who have cognitive symptoms that could impede comprehension of the information conveyed. We systematically developed and evaluated informational materials for use in pre-test counseling and post-test disclosures of amyloid imaging research results in mild cognitive impairment (MCI). Using simulated sessions, persons with MCI and their family care partners (N = 10 dyads) received fictitious but realistic information regarding brain amyloid status, followed by an explanation of how results impact Alzheimer's disease risk. Satisfaction surveys, comprehension assessments, and focus group data were analyzed to evaluate the materials developed. The majority of persons with MCI and their care partners comprehended and were highly satisfied with the information presented. Focus group data reinforced findings of high satisfaction and included 6 recommendations for practice: 1) offer pre-test counseling, 2) use clear graphics, 3) review participants' own brain images during disclosures, 4) offer take-home materials, 5) call participants post-disclosure to address emerging questions, and 6) communicate seamlessly with primary care providers. Further analysis of focus group data revealed that participants understood the limitations of amyloid imaging, but nevertheless viewed the prospect of learning one's amyloid status as valuable and empowering.

[Effects of the recipient's response on the emotions and cognitions of female undergraduates disclosing negative emotional experiences in interpersonal relationships].

Endo, Hiroko; Yukawa, Shintaro

2013-04-01

The relationship between a recipient's response to a disclosure of negative emotional experiences, and the resulting negative emotions, hesitation in self-disclosure (interpersonal and intra-personal hesitation), and negatively-confused thoughts of the person making the disclosure were investigated. Female undergraduates (N=271) were asked to write about angry or sad events in their interpersonal relationships that they had disclosed to someone. Then they completed a questionnaire assessing the recipient's responses, negative emotions such as anger and depression caused by the recipient's responses, hesitation in self-disclosure about the events, and negatively-confused thoughts about the events. The results of covariance structure analysis indicated that a recipient's rejection in response to the disclosure of negative emotional experiences resulted in negative thoughts caused by an increase of negative emotions and hesitation in self-disclosure. The results also showed that a recipient's acceptance also increased depression in the person making the self-disclosure, which intensified the intra-personal hesitation, and increased negatively-confused thoughts.

The purpose of this study is to determine the effect of assertive impression management (IM) tactics, such as personal storytelling and self-promotion, on job interview outcomes of people with epilepsy. Specifically, the effect of IM on interviewers' subjective impressions and evaluation of hireability of job candidates with epilepsy were examined. Ninety-nine master's level graduate students majoring in business or human resources were randomly assigned to three experimental conditions to view one of three 15-min video clips of a job applicant interviewing for a technical computer sales position. The three experimental conditions were (1) job applicant who did not disclose any disability, (2) job applicant with epilepsy who did not use IM tactics, and (3) job applicant with epilepsy who used IM tactics. After watching the job interview video portraying the experimental conditions, participants were asked to rate the job applicant in terms of general impression and hireability for the described position. The use of IM was found to have a significant effect on job interview outcomes (p business/human resources students on both general impression and hireability for the job applicant with epilepsy and IM condition were significantly higher than for the job applicant with epilepsy who did not use IM condition. Furthermore, mediation analysis revealed that general impression is a mediator for the relationship between IM and interview outcomes. This study demonstrates that IM has a significant and positive effect on job interview outcomes for persons with epilepsy. IM can be used as a powerful strategy for empowering people with epilepsy to combat disability stigma, and offset negative perceptions of employers about the potential of this population to be productive workers.

How I do it: surgical ligation of craniocervical junction dural AV fistulas.

Science.gov (United States)

Sorenson, Thomas J; La Pira, Biagia; Hughes, Joshua; Lanzino, Giuseppe

2017-08-01

Dural arteriovenous fistulas (DAVFs) of the craniocervical junction are uncommon vascular lesions, which often require surgical treatment even in the endovascular era. Most commonly, the fistula is placed laterally, and surgical ligation is performed through a lateral suboccipital craniotomy. After dural opening, the area is inspected, and the arterialized vein is identified emerging from the dura, often adjacent to the entry point of the vertebral artery, and ligated. A far lateral craniotomy is the authors' preferred surgical approach for accessing and treating dural arteriovenous fistulas of the craniocervical junction that cannot be reached endovascularly.

“How should I tell my child?” Disclosing the Diagnosis of Sex Chromosome Aneuploidies

Dennis, Anna; Howell, Susan; Cordeiro, Lisa; Tartaglia, Nicole

2017-01-01

To date, the disclosure of a sex chromosome aneuploidy (SCA) diagnosis to an affected individual has not been explored. This study aimed to assess the timing and content revealed to an affected child by his or her parent(s), resources accessed in preparation, parental feelings of preparedness, common parental concerns, and recommendations for disclosure approaches. Two online surveys were created: 1) for parents of a child with a diagnosis and 2) for individuals with a diagnosis. One-hundred thirty-nine parent surveys (XXY n=68, XXX n=21, XYY n=9, other SCAs n=41) and 67 individual surveys (XXY n=58, XXX n=9) were analyzed. Parents most frequently discussed the topics of learning disabilities (47%) and genetics (45%) with their child during the initial disclosure. A significantly greater proportion of parent respondents reported feeling prepared vs. unprepared for disclosure, regardless of their child’s diagnosis (z-test of proportions, all p’sparents most frequently accessed resources such as websites, support groups, and discussion with the child’s physician prior to disclosure, with unprepared parents accessing fewer resources (M = 2.0 ± 1.41) than prepared parents [M= 2. ± 1.56; t(101) = −2.02, pparental concerns included making the conversation age-appropriate, discussing infertility, and possible impact on the child’s self-esteem. Both parent and individual respondents endorsed being honest with the child, disclosing the diagnosis early and before puberty, and discussing the diagnosis gradually over time. These results provide recommendations for parents, and suggest benefits from additional resources and supports to alleviate concerns when approaching diagnosis disclosure. PMID:25179748

Nondisclosure of traditional and complementary medicine (T&CM) use may cause individual to be at risk of undue harm. This study aimed to explore patient's experience and views on their decision to disclose the use of T&CM to the doctor. An exploratory qualitative study using in-depth interview involving 10 primary care clinics attendees in Kuching was conducted. The results indicated that disclosure of T&CM use will motivate them to get information, increase doctor's awareness, and get support from family and friends for disclosure. Fear of negative relationship and negative response from doctors was a barrier for disclosure. Doctor's interpersonal and communication skills of being involved, treating patients respectfully, listening attentively, respecting privacy, and taking time for the patient were a critical component for disclosure. Intrapersonal trust regarding doctor influences their satisfaction on healthcare. Women are more open and receptive to a health concern and expressing negative emotions and tend to share problems, whereas men always described themselves as healthy, tended to keep their own personal feeling to themselves, and tended to not share. The doctor should consider gender differences in disclosure, their attitude towards T&CM use, and gained patient's trust in the delivery of healthcare services. Good interpersonal and communication skills must be maintained between doctor and patients. PMID:29636778

Full Text Available Objective: To assess the nutritional value of weight-loss diets disclosed in non-scientific magazines. Methods: A quantitative cross-sectional study carried out in two phases (first investigation in 2007; second investigation in 2009, in which 120 weight-loss diets were randomly selected from 24 magazines divided into three groups based on cost. The menus were evaluated with regard to calories, macronutrients and fiber, using the Diet Pro 2 program. The SPSS program (version 15.0 was used for statistical analysis, with the results expressed as mean, standard deviation and confidence intervals. Two-way analysis of variance (ANOVA with Tukey’s paired post hoc comparison was used for the quantitative study of the nutrients in each group of magazines and each phase of the study. The Student’s t-test was used for the comparisons of mean values obtained with the diets and established recommendations. The level of significance was set at 5.0%. Results: The energy supply was higher in 2007. Over time, mean protein content in the diets diminished, lipid content remained similar and glucose content increased. Based on the recommended values, the diets were characterized as hypoglycemic, high-protein and normolipidemic. The content of micronutrients was lower than recommended amounts in both years assessed. The fiber content increased in the second year in relation to the first, but did not reach the recommended level. Conclusion: Diets showed inadequacies of macro and micronutrients in the two studied years, with an imbalance between their components.

Tinnitus, occurring at least once in a lifetime in about 10–20% of the population, is an important clinical problem with complex etiology. Rare causes of tinnitus include cranial dural arteriovenous fistulas (DAVFs), which are usually small lesions consisting of abnormal connections between branches of dural arteries and venous sinuses or veins. Authors present a case of a 44-year-old woman with persistent, unilateral, treatment-resistant pulsatile tinnitus caused by a small dural arteriovenous fistula revealed in computed tomography angiography. Computed tomography angiography is a useful diagnostic method that in some cases allows for establishing the cause of unilateral, pulsatile tinnitus

Full Text Available Abstract Background Despite endorsement by national organizations, the impact of screening for intimate partner violence (IPV is understudied, particularly as it occurs in different clinical settings. We analyzed interviews of IPV survivors to understand the risks and benefits of disclosing IPV to clinicians across specialties. Methods Participants were English-speaking female IPV survivors recruited through IPV programs in Massachusetts. In-depth interviews describing medical encounters related to abuse were analyzed for common themes using Grounded Theory qualitative research methods. Encounters with health care clinicians were categorized by outcome (IPV disclosure by patient, discovery evidenced by discussion of IPV by clinician without patient disclosure, or non-disclosure, attribute (beneficial, unhelpful, harmful, and specialty (emergency department (ED, primary care (PC, obstetrics/gynecology (OB/GYN. Results Of 27 participants aged 18–56, 5 were white, 10 Latina, and 12 black. Of 59 relevant health care encounters, 23 were in ED, 17 in OB/GYN, and 19 in PC. Seven of 9 ED disclosures were characterized as unhelpful; the majority of disclosures in PC and OB/GYN were characterized as beneficial. There were no harmful disclosures in any setting. Unhelpful disclosures resulted in emotional distress and alienation from health care. Regardless of whether disclosure occurred, beneficial encounters were characterized by familiarity with the clinician, acknowledgement of the abuse, respect and relevant referrals. Conclusion While no harms resulted from IPV disclosure, survivor satisfaction with disclosure is shaped by the setting of the encounter. Clinicians should aim to build a therapeutic relationship with IPV survivors that empowers and educates patients and does not demand disclosure.

Although peer support in response to online disclosures of suicidality may be imperative for suicide prevention efforts, little is known as to how often support is provided or what predicts giving support. This study addresses this issue by investigating the odds of providing peer support in response to simulated online disclosures of suicidality. While interacting with a simulated Facebook newsfeed, participants (N = 690, M age  = 20.24, 527 female) were given the opportunity to leave comments on two posts disclosing low, moderate, or severe risk for suicide. Participants also completed questionnaires on their symptoms of depression and anxiety, experience with a loved one's suicidality, and Facebook use strategies. Only 33.6% of participants left a positive, supportive comment on at least one of the two suicide posts. Content severity, experience with a loved one's suicide attempts, and use of Facebook to meet people were predictive of providing positive comments. These findings suggest that young adults vary in their propensity to provide support after encountering a suicide disclosure online and that giving support is driven by a combination of contextual and intrapersonal factors. © 2018 The American Association of Suicidology.

Performance enhancement in the workplace: why and when healthy individuals should disclose their reliance on pharmaceutical cognitive enhancers.

Science.gov (United States)

Garasic, Mirko D; Lavazza, Andrea

2015-01-01

The use of pharmaceuticals cognitive enhancers (PCE) has been stirring growing interest, not only in the scientific domain but also in the popular media, and has probably had some increase recently in academic, professional and military quarters. So this phenomenon is deemed as a normal procedure aimed at improving the performance of an individual as well as the overall standards of an organization. Although the vast majority of countries have some kind of restrictions to reduce the wide non-medical usage of PCE, these can be overcome quite easily. In arguing for our explicit claim that, in many contexts, the use of cognitive enhancers should be disclosed-as a moral and socially relevant duty-we maintain that PCE present typical, or at least not rare, properties. The features are the following: (a) the enhancer has acute and/or chronic effects. In the first case, shortly after taking the drug the performance is significantly better than average; in the second case, there is a growing or lasting effect, which, however, is poised to diminish when one stops taking the drug; (b) those effects are significant (there is a difference in the outcome considered between taking and not taking the drug) and sometimes dramatic; and (c) a third feature, not directly related to enhancers as such, is their varying safety, availability, and legal permissibility, which might either induce people to take them or refrain them from doing so. We will consider the issue of fairness due to "unenhanced" people as well as the potentially dysfunctional social consequences of an undisclosed PCE use.

Did I Tell You That? Ethical Issues Related to Using Computational Methods to Discover Non-Disclosed Patient Characteristics.

Widespread availability of electronic health records coupled with sophisticated statistical methods offer great potential for a variety of applications for health and disease surveillance, developing predictive models and advancing decision support for clinicians. However, use of "big data" mining and discovery techniques has also raised ethical issues such as how to balance privacy and autonomy with the wider public benefits of data sharing. Furthermore, electronic data are being increasingly used to identify individual characteristics, which can be useful for clinical prediction and management, but were not previously disclosed to a clinician. This process in computer parlance is called electronic phenotyping, and has a number of ethical implications. Using the Belmont Report's principles of respect for persons, beneficence, and justice as a framework, we examined the ethical issues posed by electronic phenotyping. Ethical issues identified include the ability of the patient to consent for the use of their information, the ability to suppress pediatric information, ensuring that the potential benefits justify the risks of harm to patients, and acknowledging that the clinician's biases or stereotypes, conscious or unintended, may become a factor in the therapeutic interaction. We illustrate these issues with two vignettes, using the person characteristic of gender minority status (i.e., transgender identity) and health history characteristic of substance abuse. Data mining has the potential to uncover patient characteristics previously obscured, which can provide clinicians with beneficial clinical information. Hence, ethical guidelines must be updated to ensure that electronic phenotyping supports the principles of respect for persons, beneficence, and justice. © The Author(s) 2016.

communication regarding the treatment options available and prognosis). Review authors independently examined all reports from the searches for any relevant studies. We planned to extract data independently. For binary outcomes, we would have calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we would have estimated the mean difference (MD) between groups and its 95% CI. We would have employed a random-effects model for analyses. We planned to assess risk of bias for included studies. We created a 'Summary of findings' table using GRADE. The searches identified 44 records which appeared to be relevant to the aims of the review. We obtained full reports for seven potential studies; however, after close inspection none of these studies met the inclusion criteria. Good communication of diagnosis can affect treatment planning, compliance and patient outcomes, especially in the case of conditions such as schizophrenia, which has the potential to cause serious life disruption for both people with schizophrenia and their carers. Currently, there is no evidence based on findings from RCTs assessing the effects of communication strategies for disclosing the diagnosis of schizophrenia and related disorders. Research is required.

Children of the closet: a measurement of the anxiety and self-esteem of children raised by a non-disclosed homosexual or bisexual parent.

Murray, Paul D; McClintock, Karen

This research examined whether a parent's non-disclosure of his or her homosexual or bisexual orientation within the family unit negatively affects self-esteem and anxiety in children, as measured in adulthood. Thirty-six subjects indicated that they had not known of their parent's sexual orientation until an average age of sixteen for the children of lesbian or bisexual mothers, and twenty-two for the children of gay or bisexual fathers. This group's scores on the Rosenberg Self-Esteem Scale, the Marlowe Crowne Social Desirabilty Scale and the State-Trait Anxiety Scale were compared to scores obtained by sixty-three participants who did not have a homosexual/bisexual parent. The number of years a secretive environment surrounded the child was measured, as were participants' attitudes about the secret sexual identity. Although the study did not find that adults previously raised with a closeted parent had significantly higher levels of anxiety or lower levels of self-esteem, results indicated that those who had been raised as children with non-disclosed lesbian mothers showed a significantly higher level of self-esteem than participants with heterosexual parents. Implications of the findings for the targeted population are discussed.

Através de um questionário semi-estruturado, entrevistou-se 25 mulheres internadas no Hospital Universitário da UFRJ, no período anterior à disponibilização das drogas combinadas. A maioria referiu baixa escolaridade, ocupações de baixa qualificação ou eram donas de casa, sendo sua renda familiar, em alguns casos, pior que a média dos usuários deste hospital. A representação predominante sobre risco associava a Aids a uma "doença do outro" e DSTs eram percebidas como infecções masculinas, embora várias relatassem episódios destas, anteriormente ao HIV. Elas tiveram seu diagnóstico/tratamento só após o adoecimento ou morte do companheiro e ou filho.

This work aimed to verify if maximal electrically evoked single twitch (STmax) scan discloses the relative functional weight of fast and slow small bundles of fibres (SBF) in determining the contractile features of tibialis anterior (TA) with ageing. SBFs were recruited by TA main motor point stimulation through 60 increasing levels of stimulation (LS): 20 stimuli at 2Hz for each LS. The lowest and highest LS provided the least ST and STmax, respectively. The scanned STmax was decomposed into individual SBF STs. They were identified when twitches from adjacent LS were significantly different and then subtracted from each other. Nine young (Y) and eleven old (O) subjects were investigated. Contraction time (CT) and STarea/STpeak (A/PT) were calculated per each SBF ST. 143 and 155 SBF STs were obtained in Y and O, respectively. Y: CT and A/PT range: 45-105ms and 67-183mNs/mN, respectively. Literature data set TA fast fibres at 34% so, from the arrays of CT and A/PT, 65ms and 100mNs/mN were identified as the upper limit for SBF fast ST classification. O: no SBF ST could be classified as fast. STmax scan reveals age-related changes in the relative contribution of fast and slow SBFs to the overall muscle mechanics.

The majority of HIV-infected children in sub-Saharan Africa have not been informed of their HIV status. Caregivers are reluctant to disclose HIV status to their children because of concern about the child's ability to understand, parental sense of guilt, and fear of social rejection and isolation. We hypothesized that the low prevalence of pediatric HIV disclosure in Ghana is due to lack of accurate HIV information and high HIV stigma among caregivers. This is a preliminary analysis of baseline data of an HIV pediatric disclosure intervention study in Ghana ("Sankofa"). "Sankofa" - is a two-arm randomized controlled clinical trial comparing disclosure intervention plus usual care (intervention arm) vs usual care (control arm) at Korle-Bu Teaching Hospital (KBTH; control arm) and Komfo-Anokye Teaching Hospital (KATH; intervention arm). We enrolled HIV-infected children, ages 7-18 years who do not know their HIV status, and their caregivers. Baseline data of caregivers included demographic characteristics; Brief HIV Knowledge Questionnaire (HIV-KQ-18); Brief Illness Perception Questionnaire; and HIV Stigma Scale. Simple and multivariable linear regression analyses were used to assess the relationship between caregiver characteristics and HIV knowledge, stigma, and illness perception. Two hundred and ninety-eight caregivers were enrolled between January 2013 and July 2014 at the two study sites; KBTH (n = 167) and KATH (n = 131). The median age of caregivers was 41 years; 80.5% of them were female and about 60% of caregivers were HIV-positive. Seventy-eight percent of caregivers were self-employed with low household income. In both unadjusted and adjusted analyses, HIV negative status and lower level of education were associated with poor scores on HIV-KQ. HIV positive status remained significant for higher level of stigma in the adjusted analyses. None of the caregiver's characteristics predicted caregiver's illness perception.

Full Text Available This paper concentrates on information disclosure regarding IAS 23, being included in accounting research field. It comprises an empirical study on the correlation between information published by companies in consolidated financial statements with respect to borrowing cost policies and a series of variables that characterize a firm. The objectives of this paper involve estimating and establishing an econometric model in which is assumed that disclosure index for information required by IAS 23 depends on certain elements in the form of country of origin, sales, total assets, debt ratio, ROA and ROE. International accounting literature presents a series of studies on the subject of compliance with IAS disclosure requirements. Similar with this paper, various authors considered annual reports as starting point for data gathering in their reasearch on disclosure phenomena. The criteria used for data gathering, processing and analysing have been previously used in a successful manner by important scientists who published in accounting field. The methodology used involves Disclosure Index computation, as well as SPSS data processing, analysis and interpretation of results. Results show that the model is valid, meaning that there is correlation between information disclosure with respect to IAS 23 and the analyzed variables. According to our estimated econometric model, most of the variables maintain a certain influence on disclosure as we can observe a significant correlation level between the studied elements. This research contributes to the development of both accounting field and international accounting literature, by studying borrowing costs disclosed information in relation to certain elements that best characterize the activity of a company. Although an empirical paper, it concentrates also on accounting practices, as it uses real data extracted from annual reports and consolidated financial statements.

Full Text Available BACKGROUND: Triatoma dimidiata is among the main vectors of Chagas disease in Latin America. However, and despite important advances, there is no consensus about the taxonomic status of phenotypically divergent T. dimidiata populations, which in most recent papers are regarded as subspecies. METHODOLOGY AND FINDINGS: A total of 126 cyt b sequences (621 bp long were produced for specimens from across the species range. Forty-seven selected specimens representing the main cyt b clades observed (after a preliminary phylogenetic analysis were also sequenced for an ND4 fragment (554 bp long and concatenated with their respective cyt b sequences to produce a combined data set totalling 1175 bp/individual. Bayesian and Maximum-Likelihood phylogenetic analyses of both data sets (cyt b, and cyt b+ND4 disclosed four strongly divergent (all pairwise Kimura 2-parameter distances >0.08, monophyletic groups: Group I occurs from Southern Mexico through Central America into Colombia, with Ecuadorian specimens resembling Nicaraguan material; Group II includes samples from Western-Southwestern Mexico; Group III comprises specimens from the Yucatán peninsula; and Group IV consists of sylvatic samples from Belize. The closely-related, yet formally recognized species T. hegneri from the island of Cozumel falls within the divergence range of the T. dimidiata populations studied. CONCLUSIONS: We propose that Groups I-IV, as well as T. hegneri, should be regarded as separate species. In the Petén of Guatemala, representatives of Groups I, II, and III occur in sympatry; the absence of haplotypes with intermediate genetic distances, as shown by multimodal mismatch distribution plots, clearly indicates that reproductive barriers actively promote within-group cohesion. Some sylvatic specimens from Belize belong to a different species - likely the basal lineage of the T. dimidiata complex, originated ~8.25 Mya. The evidence presented here strongly supports the proposition

The importance of finding and development costs in the petroleum industry and the issue of how they can be either manipulated or misunderstood was discussed. Finding and development costs are usually expressed in terms of $/BOE (barrel of oil equivalents) and reflect the total capital expenditures divided by the total reserves replaced and added. Various examples of the importance of finding and development costs in making investment decisions were used to illustrate the effects of potential bias by the resource company, and the need for care and understanding of what the numbers issued by the company actually mean. In general, low and consistent finding and development costs, combined with good netbacks, are the key to value added for shareholders. tabs

Chemical inhibition of chromatin-mediated signaling involved proteins is an established strategy to drive expression networks and alter disease progression. Protein methyltransferases are among the most studied proteins in epigenetics and, in particular, disruptor of telomeric silencing 1-like (DOT1L) lysine methyltransferase plays a key role in MLL-rearranged acute leukemia Selective inhibition of DOT1L is an established attractive strategy to breakdown aberrant H3K79 methylation and thus overexpression of leukemia genes, and leukemogenesis. Although numerous DOT1L inhibitors have been several structural data published no pronounced computational efforts have been yet reported. In these studies a first tentative of multi-stage and LB/SB combined approach is reported in order to maximize the use of available data. Using co-crystallized ligand/DOT1L complexes, predictive 3-D QSAR and COMBINE models were built through a python implementation of previously reported methodologies. The models, validated by either modeled or experimental external test sets, proved to have good predictive abilities. The application of these models to an internal library led to the selection of two unreported compounds that were found able to inhibit DOT1L at micromolar level. To the best of our knowledge this is the first report of quantitative LB and SB DOT1L inhibitors models and their application to disclose new potential epigenetic modulators.

Disclosed Values of Option-Based Compensation

DEFF Research Database (Denmark)

Bechmann, Ken L.; Hjortshøj, Toke Lilhauge

New accounting standards require firms to expense the costs of option-based compensation (OBC), but the associated valuations offer many challenges for firms. Earlier research has documented that firms in the U.S. generally underreport the values of OBC by manipulating the inputs used for valuation......-Scholes parameters in their valuations. Furthermore, firms determine the expected time to maturity in a way that is generally consistent with the guidelines provided by the new accounting standards. The findings differ from those of the U.S., but is consistent with the more limited use of OBC and the lower level...

Disclosing Risk Information: Assessing the Benefits

International Nuclear Information System (INIS)

Beierle, Thomas C.

2003-01-01

This paper describes a framework for examining the benefits of risk information disclosure and illustrates the framework through brief case studies of three information disclosure programs in the United States. I describe a general framework for analyzing the benefits of information disclosure and illustrate the framework by analyzing three disclosure programs in the United States: risk management planning (RMP), which provides detailed information on chemical accident risks and prevention; materials accounting, which provides information on how chemicals travel through processes at industrial facilities; and the Sector Facility Indexing Project (SFIP), which consolidates enforcement, compliance, and other data into a package of environmental performance indicators. This paper has outlined the types of benefits information disclosure programs ought to seek to achieve. Normative right-to-know benefits have been limited in some program because of intentionally circumscribed information sharing and apparent public disinterest. Substantive benefits have been more apparent, with many firms, agencies, NGOs, and others being able to point to the value of newly revealed information in better understanding environmental problems and the means to correct them. Instrumental benefits have been mixed, and firms appear to be responding to many motivations - not just public pressure - in deciding whether to improve environmental performance

1996-02-01

Cardiac tamponade secondary to systemic lupus erythematosus is rare and has a very serious prognosis. The authors report a case of cardiac tamponade confirmed by echocardiography, which constituted the presenting sign of systemic lupus erythematosus in a 20-year-old patient, who required emergency pericardial aspiration. The diagnosis of systemic lupus erythematosus was established on the basis of the combination of pericardial involvement, non-erosive arthritis, leukopenia with lymphopenia, presence of LE cells and anti-native DNA antibodies and positive antinuclear antibody titre of 1/2560. The clinical course was favourable in response to 3 months of corticosteroid treatment. The possibility of SLE should be considered in any case of cardiac tamponade in a young patient in which the aetiology is not explained.

To self-disclose or not self-disclose? A systematic review of clinical self-disclosure in primary care.

Science.gov (United States)

Arroll, Bruce; Allen, Emily-Charlotte Frances

2015-09-01

There is a debate in medicine about the value of self-disclosure by the physician as a communication tool. To review the empirical literature of self-disclosure in primary care. Systematic review of empirical literature relating to self-disclosure by primary care physicians (including US paediatricians) from seven electronic databases (MEDLINE(®), Scopus, PsycINFO, Embase, Social Sciences Citation Index, EBSCOhost, and Cochrane Central Register of Controlled Trials [CENTRAL]). Databases were searched for empirical studies on self-disclosure and primary care published from 1946 to 28 November 2014, as well as references from primary studies. The search was extended to include working papers, theses, and dissertations. Nine studies were identified, with response rates ranging from 34% to 100%, as well as several not reported. Self-disclosure occurred in 14-75% of consultations, the most from paediatricians. Self-disclosure had intended benefit; however, one standardised patient study found that 85% of self-disclosures were not useful as reported by the transcript coders. Conflicting data emerged on the self-disclosure outcome. This is the first systematic review of self-disclosure in primary care and medicine. Self-disclosure appears to be common and has the potential to be helpful when used judiciously. Few studies examined the impact on patients, and no studies considered the individual patient perspective nor the content which results in benefit or harm. No evidence was found of any training into how to deal with self-disclosure. © British Journal of General Practice 2015.

Caregiver perceptions and motivation for disclosing or concealing the diagnosis of HIV infection to children receiving HIV care in Mbarara, Uganda: a qualitative study.

Directory of Open Access Journals (Sweden)

Julius Kiwanuka

Full Text Available Disclosure of the diagnosis of HIV to HIV-infected children is challenging for caregivers. Despite current recommendations, data suggest that levels of disclosure of HIV status to HIV-infected children receiving care in resource-limited settings are very low. Few studies describe the disclosure process for children in these settings, particularly the motivators, antecedent goals, and immediate outcomes of disclosure to HIV-infected children. This study examined caregivers' perception of the disclosure concept prior to disclosure, their motivation towards or away from disclosure, and their short- and long-term intentions for disclosure to their HIV-infected children.In-depth interviews were conducted with primary caregivers of 40 HIV-infected children (ages 5-15 years who were receiving HIV care but did not know their HIV status.Caregivers of HIV-infected children mainly perceived disclosure as a single event rather than a process of gradual delivery of information about the child's illness. They viewed disclosure as potentially beneficial both to children and themselves, as well as an opportunity to explain the parents' role in the transmission of HIV to the children. Caregivers desired to personally conduct the disclosure; however, most reported being over-whelmed with fear of negative outcomes and revealed a lack of self-efficacy towards managing the disclosure process. Consequently, most cope by deception to avoid or delay disclosure until they perceive their own readiness to disclose.Interventions for HIV disclosure should consider that caregivers may desire to be directly responsible for disclosure to children under their care. They, however, need to be empowered with practical skills to recognize opportunities to initiate the disclosure process early, as well as supported to manage it in a phased, developmentally appropriate manner. The potential role for peer counselors in the disclosure process deserves further study.

To disclose or not to disclose: How global competition for foreign direct investment influences transparency reforms in extractive industries

International Nuclear Information System (INIS)

Öge, Kerem

2016-01-01

In the last decade, the Extractive Industries Transparency Initiative (EITI) has grown in both popularity and influence. The ascendance of EITI is surprising because traditionally, leaders of resource-rich states prefer to tightly control their extractive industries. This paper investigates the underlying causes of EITI membership in order to understand its acceptance, even among some of the most authoritarian regimes. The paper argues that leaders of resource-rich countries use the EITI to consolidate their international prestige as eager reformers, which serves to both maintain and lure foreign investment. The cross-national and interrupted time series analyses reveal that EITI members not only have higher FDI levels compared to non-members, but these investments increase once countries join the initiative. - Highlights: • I investigate the underlying causes of EITI membership. • I argue that leaders use the EITI to both maintain and lure foreign investment. • EITI members have higher FDI levels compared to non-members. • FDI levels increase once countries join the EITI. • The results highlight a utilitarian use of the EITI by corrupt governments.

Psychological and social correlates of HIV status disclosure: the significance of stigma visibility.

Science.gov (United States)

Stutterheim, Sarah E; Bos, Arjan E R; Pryor, John B; Brands, Ronald; Liebregts, Maartje; Schaalma, Herman P

2011-08-01

HIV-related stigma, psychological distress, self-esteem, and social support were investigated in a sample comprising people who have concealed their HIV status to all but a selected few (limited disclosers), people who could conceal but chose to be open (full disclosers), and people who had visible symptoms that made concealing difficult (visibly stigmatized). The visibly stigmatized and full disclosers reported significantly more stigma experiences than limited disclosers, but only the visibly stigmatized reported more psychological distress, lower self-esteem, and less social support than limited disclosers. This suggests that having a visible stigma is more detrimental than having a concealable stigma. Differences in psychological distress and self-esteem between the visibly stigmatized and full disclosers were mediated by social support while differences between the visibly stigmatized and limited disclosers were mediated by both social support and stigma. These findings suggest that social support buffers psychological distress in people with HIV.

HIV serostatus disclosure among gay and bisexual men in four American cities: general patterns and relation to sexual practices.

Science.gov (United States)

Wolitski, R J; Rietmeijer, C A; Goldbaum, G M; Wilson, R M

1998-10-01

The present study examined patterns of serostatus disclosure among previously untested HIV-seropositive and HIV-seronegative gay and bisexual men recruited from four American cities (n = 701). Six months after learning their HIV serostatus, 97% of study participants had disclosed their test results to at least one other individual. Consistent with earlier studies, test results were most frequently shared with friends and the respondent's primary partner. HIV serostatus was disclosed less frequently to family members, co-workers, and non-primary sex partners. Compared with HIV-seronegative men, HIV-seropositive men were more likely to have disclosed their status to a health care provider and less likely to have shared this information with family members. Of seropositive men, 11% did not disclose their serostatus to their primary partner and 66% did not disclose to a non-primary sex partner. Of HIV-seropositive men with one or more non-primary partners, 16% of those who did not disclose their serostatus reported inconsistent condom use during anal intercourse with these partners. No significant differences in self-reported sexual practices were observed for HIV-seropositive disclosers versus non-disclosers. Compared with HIV-seronegative men who did not disclose, seronegative men who shared information about their serostatus were more likely to have had receptive anal intercourse with their primary partner (p masturbation (p < 0.005), receptive oral sex (p < 0.005) and insertive anal intercourse (p < 0.05) with non-primary partners. No significant differences were observed between disclosers and non-disclosers with regard to condom use. Implications of the findings for future research and HIV prevention programmes are discussed.

2007-01-01

Dural arteriovenous fistulas located in the vicinity of the jugular foramen are complex vascular malformations and belong to the most challenging skull base lesions to treat. The authors comprehensively analyze multiple features in a series of dural arteriovenous fistulas with transosseous arterial feeders involving the jugular bulb. Four patients who underwent surgery via the transcondylar approach to treat dural arteriovenous fistulas around the jugular foramen were retrospectively reviewed. Previously, endovascular treatment was attempted in all patients. The success of the surgical treatment was examined with postoperative angiography. Complete obliteration of the dural arteriovenous fistulas (DAVFs) was achieved in three patients, and significant flow reduction in one individual. All patients had a good postoperative outcome, and only one experienced mild hypoglossal nerve palsy. Despite extensive bone drilling, an occipitocervical fusion was necessary in only one patient with bilateral lesions. The use of an individually tailored transcondylar approach to treat dural arteriovenous fistulas at the region of the jugular foramen is most effective. This approach allows for complete obliteration of the connecting arterial feeders, and removal of bony structures containing pathological vessels.

This study addressed the issue of disclosing HIV status and sexual orientation, and explored the consequences of such disclosures among HIV-positive men who have sex with men (MSM) in China. In-depth individual interviews were conducted with 37 HIV-positive MSM. Of these participants, 3 (8.1%) disclosed neither their HIV status nor their sexual orientation to anyone; 24 (64.9%) voluntarily disclosed both their HIV-positive status and their sexual orientation; 7 (18.9%) voluntarily disclosed their HIV status only, and 3 (8.1%) involuntarily disclosed their HIV status and sexual orientation. Parents, partners, siblings and close friends were the most common disclosure targets. HIV-positive MSM were less likely to disclose their sexual orientation than their HIV status. The positive consequences of disclosure included receiving support, acquiring family care, reducing stress, improving mood and developing more positive values and beliefs. The negative consequences included the participants' perception of rejection and stigma toward themselves and their families. However, the stigma mainly comes from "outsiders" rather than family members and close friends. We did not find any differences with respect to consequences between participants who disclosed their HIV status only and those who disclosed both their HIV status and sexual orientation. In conclusion, partners, siblings and friends were main disclosure targets, and HIV positive MSM preferred to disclose their HIV serostatus than their sexual orientation. Voluntarily disclosing one's HIV status to significant others resulted in more positive consequences than negative consequences. Theses results were informative for developing mental health and coping interventions.

Lindsay, Sally; Cagliostro, Elaine; Leck, Joanne; Shen, Winny; Stinson, Jennifer

2018-03-20

Many youths with disabilities find it challenging to disclose their medical condition and request workplace accommodations. Our objective was to explore when and how young people with disabilities disclose their condition and request workplace accommodations. We conducted 17 in-depth interviews (11 females, six males) with youth with disabilities aged 15-34 (mean age 26). We analyzed our data using an interpretive, qualitative, and thematic approach. Our results showed the timing of when youth disclosed their disability to their employer depended on disability type and severity, comfort level, type of job, and industry. Youth's strategies and reasons for disclosure included advocating for their needs, being knowledgeable about workplace rights, and accommodation solutions. Facilitators for disclosure included job preparation, self-confidence, and self-advocacy skills, and having an inclusive work environment. Challenges to disability disclosure included the fear of stigma and discrimination, lack of employer's knowledge about disability and accommodations, negative past experiences of disclosing, and not disclosing on your own terms. Our findings highlight that youth encounter several challenges and barriers to disclosing their condition and requesting workplace accommodations. The timing and process for disclosing is complex and further work is needed to help support youth with disclosing their condition. Implications for rehabilitation Clinicians, educators, and employers should emphasize the importance of mentoring and leadership programs to give youth the confidence and self-advocacy skills needed to disclose and ask for accommodations in the workplace. Clinicians should advocate for the inclusion of youth with disabilities in the workforce and educate employers on the importance of doing so. Youth with disabilities need more opportunities for employment training and particularly how to disclose their disability and request workplace accommodations.

Clinical utility of self-disclosure for adults who stutter: Apologetic versus informative statements.

Science.gov (United States)

Byrd, Courtney T; Croft, Robyn; Gkalitsiou, Zoi; Hampton, Elizabeth

2017-12-01

The purpose of the present study was to explore the clinical utility of self-disclosure, particularly, whether disclosing in an informative manner would result in more positive observer ratings of the speaker who stutters than either disclosing in an apologetic manner or choosing not to self-disclose at all. Observers (N=338) were randomly assigned to view one of six possible videos (i.e., adult male informative self-disclosure, adult male apologetic self-disclosure, adult male no self-disclosure, adult female informative self-disclosure, adult female apologetic self-disclosure, adult female no self-disclosure). Observers completed a survey assessing their perceptions of the speaker they viewed immediately after watching the video. Results suggest that self-disclosing in an informative manner leads to significantly more positive observer ratings than choosing not to self-disclose. In contrast, use of an apologetic statement, for the most part, does not yield significantly more positive ratings than choosing not to self-disclose. Clinicians should recommend their clients self-disclose in an informative manner to facilitate more positive observer perceptions. Copyright © 2017. Published by Elsevier Inc.

Self-disclosure by victims of child sexual abuse (CSA) is critical to initiate legal and therapeutic intervention. Unfortunately, research indicates that lengthy delays in disclosure and even nondisclosure are common. A comprehensive review of the clinical and research literature on CSA and an overview of related bodies of literature was conducted. Areas addressed include the context of sexual abuse as it relates to disclosure, the context and elements of children's disclosures, motivational factors inhibiting disclosure, and models of the disclosure process. Ancillary and analogue research on secrecy and disclosure are also reviewed. Implications for future research and practice are discussed.

Disclosing medical errors: the view from the USA.

Science.gov (United States)

Kachalia, Allen; Bates, David W

2014-04-01

Disclosure is increasingly seen as a key component of efforts to improve safety, but does not yet reliably occur in all organizations in the U.S. We describe the experience to date with disclosure in the U.S. and illustrate the issues with specific clinical examples. Both reputational and legal concerns represent substantial barriers. The evidence to date-mostly from single sites - shows that not only is disclosure the right thing to do, it also appears to decrease malpractice risk. We also discuss the related issue of compensation-practices around this vary greatly. Underlying the push for greater disclosure is also the belief that better disclosure results in an improved culture of safety, which in turn may improve the quality and safety of care. Providers have an ethical imperative to disclosure error to patients, and the limited available evidence shows that doing so actually decreases malpractice risk. While disclosure is not yet routine practice in the U.S., the approach is clearly gaining momentum. Telling patients what happened is not enough. They also deserve an apology, and if harmed, to be made whole emotionally and financially. Greater disclosure may not only help individual patients, but may also help with improving safety overall.

Habla Privada y resolución de problemas en adolescentes de 15 años

Directory of Open Access Journals (Sweden)

Maria Cecilia Hontou

2017-05-01

Full Text Available El fenómeno de hablarse a sí mismo ha sido investigado desde diferentes perspectivas psicológicas. La psicología socio-cultural lo denomina Habla Privada (HP y lo define como una manifestación audible de lenguaje, autodirigida, con funciones de autorregulación. El HP permite orientar, monitorear y evaluar la acción. Aparece frente a una demanda cognitiva y sirve para guiar la resolución de problemas. Aunque la mayoría de las investigaciones sobre HP se han centrado en la infancia, existen estudios en adolescentes y adultos que sugieren que el HP continúa siendo una estrategia cognitiva empleada en todo el ciclo vital. Nuestro objetivo fue estudiar el HP en adolescentes y su relación con la resolución de problemas. Para ello, aplicamos la Tarea de Formación de Conceptos Artificiales Vygotski-Saharov (TFCA a 19 adolescentes de 15 años, de dos contextos socio-económicos diferentes, generando protocolos verbales y realizando un análisis microgenético de los mismos. Se identificó HP en 17 de los 19 adolescentes y se encontró una correlación directa y grande entre HP-desempeño en la tarea. Los adolescentes que tuvieron una puntuación más alta en la tarea emplearon además, más habla privada antecediendo a la acción y más evaluaciones de la acción que sus pares con una puntuación intermedia. Estos resultados aportan evidencia a la hipótesis vigotskiana sobre la relación entre lenguaje y pensamiento.

2016-12-01

Although domestic violence is increasingly identified as a workplace issue, little is known about workplace supports and the role of gender in workplace disclosure experiences. Using a subset of 2,831 people who experienced domestic violence, we examined (a) who discloses at work and to whom, and reasons for not disclosing; (b) helpfulness of disclosure recipients, including types of supports received; and (c) overall outcomes of disclosing, including negative consequences. Data were analyzed using descriptive statistics and content analysis. More than 40% of participants disclosed domestic violence at work, usually to coworkers or supervisors. They received various supports which were generally seen as helpful. Although not common, negative consequences of disclosure were reported. Men were less likely to disclose, but few other gender differences emerged. Implications for improving workplace supports are discussed.

Discreet Openness: Scholars’ Selective and Intentional Self-Disclosures Online

Directory of Open Access Journals (Sweden)

George Veletsianos

2016-08-01

Full Text Available Research into emergent forms of scholarship focuses on academics’ use of technology for learning, teaching, and research. Very little attention has been paid in the literature to scholars’ uses of social media to disclose challenging personal and professional issues. This article addresses the identified gap in the literature and presents a qualitative investigation into the types of disclosures that 16 scholars made online and their reasons for doing so. Results identify wide-ranging personal and professional disclosures. Participants disclosed not only about academia-related issues but also about challenges pertaining to family, mental health, physical health, identity, and relationships. Some scholars disclosed as a way to grapple with challenges they faced; others disclosed tactically, sharing information for political rather than personal reasons. Yet others disclosed as a way to welcome care in their lives. In all instances, though, disclosures were selective, intentional, and approached with foresight.

Martinelli, Vittorio; Ghezzi, A; Montanari, E; Radaelli, M; Comi, G; Bossa, R

2012-12-01

Communicating the diagnosis of multiple sclerosis (MS) is a challenging task, often undertaken with discomfort by most neurologists. Only a few studies have investigated patients' satisfaction with timing and way of receiving the diagnosis, but surveys regarding physicians' attitude towards diagnosis disclosure are even more limited. The goal of this work was to highlight Italian neurologists' behavioral and emotional approach to MS patients, making them sensitive to their difficulties and to the importance of an empathic relationship. The majority of Italian neurologists participating in our study have a good perception of their ability to manage this difficult communicating process and believe in the great effect this moment may have on a life-long disease experience. Improving communication skills may help the therapeutic alliance, enhancing patients' acceptance of the disease, as well as motivation and adherence to treatment.

Exploring the links between interpersonal trust and the reasons underlying gay and bisexual males' disclosure of their sexual orientation to their mothers.

Science.gov (United States)

Boon, S D; Miller, R J

1999-01-01

This paper examines the role that interpersonal trust plays in gay and bisexual males' accounts of the factors that led them to decide to reveal or to withhold their sexual identities from their mothers. Fifty men completed a questionnaire about their coming out experiences in the context of their relationships with their mothers. As part of this questionnaire, they indicated whether or not they had disclosed their sexual orientation to their mothers and explained the basis for their decision in this regard. A content analysis of the explanations offered supports findings from previous research which suggest that a considerable range of motivations underlie the decision to disclose (or not to disclose). More importantly, consistent with expectations that the mother's trustworthiness would emerge as a principle concern in participants' responses, several of the classes of explanation identified in disclosers' and non-disclosers' decision accounts suggest that the move toward disclosure is guided in part by the climate of trust existing in individuals' relationships with their mothers.

The underreporting of rape is well known; however, there is less information on women who fail to disclose to anyone. This online study suggests that 24% of 242 women who were non-disclosing compared with those who had disclosed were significantly less likely to seek treatment for emotional injuries. Also, almost two thirds of non-disclosing women believed the abuse was their fault versus 39.1% of women with prior disclosure. Of clinical interest is that regardless of disclosure pattern, there was no significant difference in reports of depression, anxiety, or posttraumatic stress disorder, and the majority of respondents endorsed support for online counseling over telephone or individual contact. © The Author(s) 2016.

Investigating Initial Disclosures and Reactions to Unexpected, Positive HPV Diagnosis.

Smith, Rachel A; Hernandez, Rachael; Catona, Danielle

2014-07-01

Initial disclosures of health conditions are critical communication moments. Existing research focuses on disclosers; integrating confidants into studies of initial disclosures is needed. Guided by the disclosure decision-making model (DD-MM; Greene, 2009), this study examined what diagnosed persons and confidants may say when faced with unexpected test results and unexpected disclosures, respectively. Participants ( N = 151) recorded an audio-visual message for another person, after imagining that they or the other person had just received unexpected, positive HPV test results. The qualitative analysis revealed four themes: (1) impression management and social distance, (2) invisible symptoms and advice regarding future disclosures, (3) expressing and acknowledging emotional reactions, and (4) misunderstandings and lacking knowledge about HPV. These findings suggested that DD-MM may be a relevant framework for understanding not only when disclosers share, but what disclosers and confidants say in early conversations about new diagnoses. While disclosers' and confidants' messages showed marked similarities, important differences appeared. For example, confidants focused on assuaging disclosers' fear about the consequences, whereas disclosers expressed distress related to their uncertainty about the prognosis of an HPV infection and how to prepare for next steps. The discussion highlighted implications for the DD-MM, HPV disclosures, and future interventions.

Why tell children: A synthesis of the global literature on reasons for disclosing or not disclosing an HIV diagnosis to children 12 and under

Directory of Open Access Journals (Sweden)

Beatrice J. Krauss

2016-09-01

Full Text Available While the psychological and health benefits of knowing one’s HIV diagnosis have been documented for adults and adolescents, practice is still in development for younger children. Moderating conditions for whether or not to tell a child he/she has HIV vary by region and local context. They include accessibility of treatment, consideration of HIV as a stigmatizing condition, prevalence of HIV and an accompanying presumption that any illness is HIV-related, parent or caregiver concerns about child reactions, child’s worsening health, assumptions about childhood and child readiness to know a diagnosis, and lack of policies such as those that would prevent bullying of affected children in schools. In this systematic review of the global literature, we summarize the reasons caregivers give for telling or not telling children 12 and under their HIV diagnosis. We also include articles in which children reflect on their desires for being told. While a broad number of reasons are given for telling a child—e.g., to aid in prevention, adaptation to illness (e.g., primarily to promote treatment adherence, understanding social reactions, and maintaining the child-adult relationship—a narrower range of reasons, often related to immediate child or caregiver well-being or discomfort, are given for not telling. Recommendations are made to improve the context for disclosure by providing supports before, during and after disclosure and to advance the research agenda by broadening samples and refining approaches.

Product Disclosure Sheet of Islamic Bank in Malaysia: Home Financing

Directory of Open Access Journals (Sweden)

Muhammad Fakhirin, C. M.

2016-12-01

Full Text Available The diversity of financial products offered by the financial service providers along with the upwards trend of home financing in Malaysia has significant relationship with information disclosure about the products. Consistency in disclosing essential information is aimed at minimizing the mis-selling of financial products to avoid gharar (ambiguity. Therefore, the purpose of this study is to highlight the practice of disclosing information of the home financing products by five major commercial banks in Malaysia which are Maybank Islamic Berhad, CIMB Islamic Bank Berhad, Bank Islam Malaysia Berhad, Public Islamic Bank Berhad, and AmIslamic Bank Berhad. The study employs qualitative method whereby secondary data were gathered from selected Islamic Financial Institutions (IFIs websites. It reports the evaluation of the types of information which have been disclosed in the Product Disclosure Sheet of each product and the comparison between all five banks. Data gathered were analysed using frequencies via SPSS version 20. The findings show that four out of five banks have published the Product Disclosure Sheets (PDSs in their respective websites. The types of information disclosed by all banks slightly vary from each other. However, AmIslamic Bank Berhad appears to be a highly disclosed institution that relates to home financing facility, while Bank Islam Malaysia Berhad disclosed the least information in the PDSs. Besides, CIMB Islamic Bank Berhad is the only bank which did not make the PDSs available in their website.

Disclosures of funding sources and conflicts of interest in published HIV/AIDS research conducted in developing countries.

2010-08-01

Disclosures of funding sources and conflicts of interests (COI) in published peer-reviewed journal articles have recently begun to receive some attention, but many critical questions remain, for example, how often such reporting occurs concerning research conducted in the developing world and what factors may be involved. Of all articles indexed in Medline reporting on human subject HIV research in 2007 conducted in four countries (India, Thailand, Nigeria and Uganda), this study explored how many disclosed a funding source and COI, and what factors are involved. Of 221 articles that met the criteria, 67.9% (150) disclosed the presence or absence of a funding source, but only 20% (44) disclosed COI. Studies from Uganda were more likely, and those from Nigeria were less likely to mention a funding source (pfunding was more likely when: > or = 50% of the authors and the corresponding author were from the sponsoring country, the sponsor country was the USA, and the articles were published in journals in which more of the editors were from the sponsoring countries. Of the published studies examined, over a third did not disclose funding source (ie, whether or not there was a funding source) and 80% did not disclose whether COI existed. Most articles in ICMJE-affiliated journals did not disclose COI. These data suggest the need to consider alteration of policies to require that published articles include funding and COI information, to allow readers to assess articles as fully as possible.

Self-disclosure among bloggers: re-examination of social penetration theory.

Science.gov (United States)

Tang, Jih-Hsin; Wang, Cheng-Chung

2012-05-01

Based on Social Penetration theory, this study explores the topics that bloggers disclose on their blogs, and in the real world. A total of 1,027 Taiwanese bloggers participated in this online survey, which revealed that bloggers self-disclosed nine topics (attitude, body, money, work, feelings, personal, interests, experiences, and unclassified). Further, we examined the depth and width of what bloggers self-disclosed to three target audiences (online audience, best friend, and parents), confirming that their disclosure is significantly different for each of these target audiences. Bloggers seemingly express themselves to their best friends the most, followed by parents and online audiences, both in depth and in width. The "wedge model," proposed by Altman and Taylor (1973), has been extended to online relationships in this study. In comparison to male bloggers, female bloggers seemed to disclose more to their best friends and parents in their daily lives; however, no significant difference was observed in their disclosure to online audiences. Younger bloggers (<20 years old) seemed to disclose a wider range of topics; however, there was no significant difference in the depth of their disclosure on their blogs. Discussions of these results are also presented.

Disclosing discourses: biomedical and hospitality discourses in patient education materials.

Science.gov (United States)

Öresland, Stina; Friberg, Febe; Määttä, Sylvia; Öhlen, Joakim

2015-09-01

Patient education materials have the potential to strengthen the health literacy of patients. Previous studies indicate that readability and suitability may be improved. The aim of this study was to explore and analyze discourses inherent in patient education materials since analysis of discourses could illuminate values and norms inherent in them. Clinics in Sweden that provided colorectal cancer surgery allowed access to written information and 'welcome letters' sent to patients. The material was analysed by means of discourse analysis, embedded in Derrida's approach of deconstruction. The analysis revealed a biomedical discourse and a hospitality discourse. In the biomedical discourse, the subject position of the personnel was interpreted as the messenger of medical information while that of the patients as the carrier of diagnoses and recipients of biomedical information. In the hospitality discourse, the subject position of the personnel was interpreted as hosts who invite and welcome the patients as guests. The study highlights the need to eliminate paternalism and fosters a critical reflective stance among professionals regarding power and paternalism inherent in health care communication. © 2015 John Wiley & Sons Ltd.

The Impact of Incident Disclosure Behaviors on Medical Malpractice Claims.

Science.gov (United States)

Giraldo, Priscila; Sato, Luke; Castells, Xavier

2017-06-30

To provide preliminary estimates of incident disclosure behaviors on medical malpractice claims. We conducted a descriptive analysis of data on medical malpractice claims obtained from the Controlled Risk Insurance Company and Risk Management Foundation of Harvard Medical Institutions (Cambridge, Massachusetts) between 2012 and 2013 (n = 434). The characteristics of disclosure and apology after medical errors were analyzed. Of 434 medical malpractice claims, 4.6% (n = 20) medical errors had been disclosed to the patient at the time of the error, and 5.9% (n = 26) had been followed by disclosure and apology. The highest number of disclosed injuries occurred in 2011 (23.9%; n = 11) and 2012 (34.8%; n = 16). There was no incremental increase during the financial years studied (2012-2013). The mean age of informed patients was 52.96 years, 58.7 % of the patients were female, and 52.2% were inpatients. Of the disclosed errors, 26.1% led to an adverse reaction, and 17.4% were fatal. The cause of disclosed medical error was improper surgical performance in 17.4% (95% confidence interval, 6.4-28.4). Disclosed medical errors were classified as medium severity in 67.4%. No apology statement was issued in 54.5% of medical errors classified as high severity. At the health-care centers studied, when a claim followed a medical error, providers infrequently disclosed medical errors or apologized to the patient or relatives. Most of the medical errors followed by disclosure and apology were classified as being of high and medium severity. No changes were detected in the volume of lawsuits over time.

A Cycle of Redemption in a Medical Error Disclosure and Apology Program.

Science.gov (United States)

Carmack, Heather J

2014-06-01

Physicians accept that they have an ethical responsibility to disclose and apologize for medical errors; however, when physicians make a medical error, they are often not given the opportunity to disclose and apologize for the mistake. In this article, I explore how one hospital negotiated the aftermath of medical mistakes through a disclosure and apology program. Specifically, I used Burke's cycle of redemption to position the hospital's disclosure and apology program as a redemption process and explore how the hospital physicians and administrators worked through the experiences of disclosing and apologizing for medical errors. © The Author(s) 2014.

Optimism, community attachment and serostatus disclosure among HIV-positive men who have sex with men.

Science.gov (United States)

Murphy, Patrick J; Hevey, David; O'Dea, Siobhán; Ní Rathaille, Neans; Mulcahy, Fiona

2015-01-01

This study investigated the relationship between HIV health optimism (HHO) (the belief that health will remain good after HIV infection due to treatment efficacy), HIV-positive community attachment (HCA), gay community attachment (GCA) and serostatus disclosure to casual sex partners by HIV-positive men who have sex with men (MSM). Cross-sectional questionnaire data were gathered from 97 HIV-positive MSM attending an HIV treatment clinic in Dublin, Ireland. Based on self-reported disclosure to casual partners, participants were classified according to their pattern of disclosure (consistent, inconsistent or non-disclosers). Multinomial logistic regression was used to assess HHO, HCA and GCA as predictors of participants' pattern of disclosure. Classification as a non-discloser (compared to a consistent discloser) was associated with higher HHO, less HCA and greater GCA. Classification as an inconsistent discloser (compared to a consistent discloser) was associated with higher GCA. The study provided novel quantitative evidence for associations between the constructs of interest. The results suggest that (1) HHO is associated with reduced disclosure, suggesting optimism may preclude individuals reaping the benefits of serostatus disclosure and (2) HCA and GCA represent competing attachments with conflicting effects on disclosure behaviour. Limitations and areas for future research are discussed.

Disclosure and Psychological Well-Being of Sexually Abused Adolescents in Hong Kong.

Science.gov (United States)

Lam, Kindy Yuk-Ip

2015-01-01

The role of disclosure on psychological well-being of adolescents with child sexual abuse experience was investigated in a subsample of 74 disclosers among 800 adolescents recruited in the community in Hong Kong. The results supported that CSA experiences have differential impact on adolescents' psychological well-being. Family characteristics of the disclosers accounted for only a small amount of the variance in an array of psychological well-being measures. CSA characteristics were robust predictors of disclosers' sexual eroticism and externalizing behavioral symptoms. Disclosers' cognitive appraisal of CSA experience and quality of parental attachment were strong predictors of their self-esteem and internalizing behavioral problems. After controlling for the aforementioned factors, negative disclosure experience still significantly predicted lower self-esteem, higher sexual anxiety, more internalizing behavior, and more severe post-traumatic stress disorder responses. Research to understand the factors that generate negative disclosure experiences is needed for developing effective intervention strategies to mitigate the negative consequences of disclosure.

Disclosure of newly diagnosed HIV infection and condom use at first sex after diagnosis: a study of young Black men who have sex with men.

Science.gov (United States)

Crosby, Richard A; Mena, Leandro; Arnold, Trisha

2017-08-01

Background The first purpose of the present study was to determine whether young Black men who have sex with men (YBMSM) disclose their newly diagnosed HIV infection to a male or female partner, and to determine whether this disclosure is related to condom use; the second was to identify correlates of disclosing newly diagnosed HIV infection to male sex partners, including a measure of partner-related barriers to condom use. A sample of 125 HIV-infected YBMSM (age 15-29 years) provided cross-sectional data used for both study purposes. Recruitment occurred in a mid-size city in the southern US experiencing inordinately high prevalence and incidence rates of HIV among YBMSM. Significance was defined by an α level of <0.05. Eighty-eight YBMSM (70.4%) indicated disclosing their newly diagnosed HIV status to the first male partner they had sex with after being diagnosed. Of these, nine (9.1%) reported that condoms were not used during ensuing sex with that partner. However, of the men not disclosing, 27.0% reported not using condoms for ensuing sex (P=0.009). Similar findings were observed relative to sex with females (P=0.057). Regarding the second study purpose, in addition to a protective effect of advancing age, men scoring at or above the median on a measure of partner-related barriers to condom use were 2.4-fold more likely to not disclose compared with men scoring below the median (P=0.04). For YBMSM, a beneficial counselling objective relative to disclosing newly diagnosed HIV may be to help men resolve perceptions of partner-related barriers to condom use.

Participants (N = 50) wrote about a traumatic life event or their plans for the next day and completed measures of resilience and distress before disclosing (pretest) and 3 months later (posttest). Results revealed that trauma participants increased in positive self-perceptions (mastery, personal growth, self-acceptance) and decreased in distress (depression, interpersonal sensitivity, anxiety, somatization) from pretest to posttest. Control participants showed no changes except for autonomy, on which they decreased. Results suggest that in addition to reducing psychological distress, disclosing traumas change self-perception, resulting in a more resilient self-concept.

A Scalable Framework to Detect Personal Health Mentions on Twitter.

Science.gov (United States)

Yin, Zhijun; Fabbri, Daniel; Rosenbloom, S Trent; Malin, Bradley

2015-06-05

Biomedical research has traditionally been conducted via surveys and the analysis of medical records. However, these resources are limited in their content, such that non-traditional domains (eg, online forums and social media) have an opportunity to supplement the view of an individual's health. The objective of this study was to develop a scalable framework to detect personal health status mentions on Twitter and assess the extent to which such information is disclosed. We collected more than 250 million tweets via the Twitter streaming API over a 2-month period in 2014. The corpus was filtered down to approximately 250,000 tweets, stratified across 34 high-impact health issues, based on guidance from the Medical Expenditure Panel Survey. We created a labeled corpus of several thousand tweets via a survey, administered over Amazon Mechanical Turk, that documents when terms correspond to mentions of personal health issues or an alternative (eg, a metaphor). We engineered a scalable classifier for personal health mentions via feature selection and assessed its potential over the health issues. We further investigated the utility of the tweets by determining the extent to which Twitter users disclose personal health status. Our investigation yielded several notable findings. First, we find that tweets from a small subset of the health issues can train a scalable classifier to detect health mentions. Specifically, training on 2000 tweets from four health issues (cancer, depression, hypertension, and leukemia) yielded a classifier with precision of 0.77 on all 34 health issues. Second, Twitter users disclosed personal health status for all health issues. Notably, personal health status was disclosed over 50% of the time for 11 out of 34 (33%) investigated health issues. Third, the disclosure rate was dependent on the health issue in a statistically significant manner (P<.001). For instance, more than 80% of the tweets about migraines (83/100) and allergies (85

Endovascular management of dural arteriovenous fistulas of the transverse and sigmoid sinus in 150 patients

International Nuclear Information System (INIS)

Kirsch, M.; Liebig, T.; Kuehne, D.; Henkes, H.

2009-01-01

This study aimed to evaluate the safety and efficiency of the endovascular treatment of transverse-sigmoid sinus dural arteriovenous fistulas (TS d AVF). A total of 150 consecutive patients and 348 procedures were evaluated. Pulsatile tinnitus (81%), headache (15%), and intracranial hemorrhage (10%) were the most frequent manifestations of the TS d AVFs. More than half of the affected sinuses were partially or completely thrombosed. Access-wise treatment was performed transarterial (n = 33), transvenous (n = 21), or a combination thereof (n = 96). A mean of 2.4 procedures per patient was required. Immediate postprocedural occlusion rate after transarterial embolization was 30% only. Transvenous treatment alone resulted in an early occlusion rate of 81%, with delayed complete obliteration of half of the remaining fistulas. After combined transarterial/transvenous treatment, the angiographic cure rate was 54%. At follow-up, 88% of patients with residual shunt after the treatment showed complete occlusion. The cumulative complication rate was 9% (n = 13), with minor adverse events in ten patients (7%) and major complications in three patients (2%). Transvenous coil occlusion of the sinus segment with the adjacent dAVF site, eventually combined with transarterial occlusion of supplying arteries, is a very effective and well-tolerated treatment method. In selected patients, variations of these methods (e.g., sinus stenting, compartmental sinus occlusion) can be useful. (orig.)

Is disclosure of childhood rape associated with mental health outcome? Results from the National Women's Study.

Science.gov (United States)

Ruggiero, Kenneth J; Smith, Daniel W; Hanson, Rochelle F; Resnick, Heidi S; Saunders, Benjamin E; Kilpatrick, Dean G; Best, Connie L

2004-02-01

Clinicians often assert that disclosure of childhood rape is beneficial to victims because it sets the occasion for protective action and can bring them into contact with professionals trained to address rape-related mental health needs. Consistent with this is the hypothesis that victims of childhood rape who disclose their victimization soon after it occurs are at lower risk for later psychosocial difficulties relative to those who delay disclosure or never disclose. We explored this issue with a nationally representative sample of 3,220 adult women; 288 (8.9%) endorsed at least one instance of forcible sexual penetration prior to age 18. Results revealed a significantly higher past-year prevalence of posttraumatic stress disorder (PTSD) and major depressive episodes among women who waited longer than 1 month to disclose their rape relative to nondisclosers and women who disclosed within 1 month of the rape. Delayed disclosure remained associated with PTSD after controlling for demographic and rape characteristics. Patterns of disclosure were not associated with past-year substance-use problems.

Voluntary Disclosure in the Annual Reports of Financially Distressed Companies in Indonesia

Directory of Open Access Journals (Sweden)

Wijantini Wijantini

2006-09-01

Full Text Available This paper examines voluntary disclosure in the annual reports of financially distressed companies in Indonesia. The disclosure score range is between 3 percent and 49 percent with the mean and median score of 25 percent and 26 percent, respectively, at the onset of distress. The score is measured as the ratio of the total items disclosed to the maximum possible items score applicable to the firm. The most disclosed items are in the category of financial highlights and general corporate information whereas the three least disclosed items concern projections, liquidity, and research and development. Moreover, the results of this study reveal that the level of voluntary disclosure in the financially distressed firms is higher than that in non-financially distressed firms. There is no significant difference between the types of information disclosed by the 2  groups. The statistical tests are applied for various years. Consistent with findings in previous studies, the size of the firm appears to be a positive variable significantly affecting the disclosure level.

Oulasvirta, Antti; Suomalainen, Tiia; Hamari, Juho; Lampinen, Airi; Karvonen, Kristiina

2014-10-01

An online experiment (n=1,897) was carried out to understand how data disclosure practices in ubiquitous surveillance affect users' privacy concerns. Information about the identity and intentions of a data collector was manipulated in hypothetical surveillance scenarios. Privacy concerns were found to differ across the scenarios and moderated by knowledge about the collector's identity and intentions. Knowledge about intentions exhibited a stronger effect. When no information about intentions was disclosed, the respondents postulated negative intentions. A positive effect was found for disclosing neutral intentions of an organization or unknown data collector, but not for a private data collector. The findings underline the importance of disclosing intentions of data use to users in an easily understandable manner.

Disclosing bias in bisulfite assay: MethPrimers underestimate high DNA methylation.

Directory of Open Access Journals (Sweden)

Andrea Fuso

Full Text Available Discordant results obtained in bisulfite assays using MethPrimers (PCR primers designed using MethPrimer software or assuming that non-CpGs cytosines are non methylated versus primers insensitive to cytosine methylation lead us to hypothesize a technical bias. We therefore used the two kinds of primers to study different experimental models and methylation statuses. We demonstrated that MethPrimers negatively select hypermethylated DNA sequences in the PCR step of the bisulfite assay, resulting in CpG methylation underestimation and non-CpG methylation masking, failing to evidence differential methylation statuses. We also describe the characteristics of "Methylation-Insensitive Primers" (MIPs, having degenerated bases (G/A to cope with the uncertain C/U conversion. As CpG and non-CpG DNA methylation patterns are largely variable depending on the species, developmental stage, tissue and cell type, a variable extent of the bias is expected. The more the methylome is methylated, the greater is the extent of the bias, with a prevalent effect of non-CpG methylation. These findings suggest a revision of several DNA methylation patterns so far documented and also point out the necessity of applying unbiased analyses to the increasing number of epigenomic studies.

Training and practicing key elements of DME using standardized patients (SP may enhance preparedness among EM residents in performing this crucial skill in a clinical setting. Methods This training was developed to improve resident preparedness in DME in the clinical setting. Objectives included the following: the residents will be able to define a medical error; discuss ethical and professional standards of DME; recognize common barriers to DME; describe key elements in effective DME to patients and families; and apply key elements during a SP encounter. The four-hour course included didactic and experiential learning methods, and was created collaboratively by core EM faculty and subject matter experts in conflict resolution and healthcare simulation. Educational media included lecture, video exemplars of DME communication with discussion, small group case-study discussion, and SP encounters. We administered a survey assessing for preparedness in DME pre-and post-training. A critical action checklist was administered to assess individual performance of key elements of DME during the evaluated SP case. A total of 15 postgraduate-year 1 and 2 EM residents completed the training. Results After the course, residents reported increased comfort with and preparedness in performing several key elements in DME. They were able to demonstrate these elements in a simulated setting using SP. Residents valued the training, rating the didactic, SP sessions, and overall educational experience very high. Conclusion Experiential learning using SP is effective in improving resident knowledge of and preparedness in performing medical error disclosure. This educational module can be adapted to other clinical learning environments through creation of specialty-specific scenarios.

Aquatic Ecotoxicity Testing of Nanoparticles—The Quest To Disclose Nanoparticle Effects

DEFF Research Database (Denmark)

Skjolding, Lars Michael; Sørensen, Sara Nørgaard; Hartmann, Nanna B.

2016-01-01

The number of products on the market containing engineered nanoparticles (ENPs) has increased significantly, and concerns have been raised regarding their ecotoxicological effects. Environmental safety assessments as well as relevant and reliable ecotoxicological data are required for the safe...... to ENPs in aquatic test systems. Filling this gap is not straightforward, because of the broad range of ENPs and the different behavior of ENPs compared to “ordinary” (dissolved) chemicals in the ecotoxicity test systems. The risk of generating false negatives, and false positives, in the currently used...... tests is high, and in most cases difficult to assess. This Review outlines some of the pitfalls in the aquatic toxicity testing of ENPs which may lead to misinterpretation of test results. Response types are also proposed to reveal potential nanoparticle effects in the aquatic test organisms....

Disclosed dielectric and electromechanical properties of hydrogenated nitrile–butadiene dielectric elastomer

International Nuclear Information System (INIS)

Yang, Dan; Tian, Ming; Dong, Yingchao; Liu, Haoliang; Yu, Yingchun; Zhang, Liqun

2012-01-01

This paper presents a comprehensive study of the effects of acrylonitrile content, crosslink density and plasticization on the dielectric and electromechanical performances of hydrogenated nitrile–butadiene dielectric elastomer. It was found that by increasing the acrylonitrile content of hydrogenated nitrile–butadiene dielectric elastomer, the dielectric constant will be improved accompanied with a sharp decrease of electrical breakdown strength leading to a small actuated strain. At a fixed electric field, a high crosslink density increased the elastic modulus of dielectric elastomer, but it also enhanced the electrical breakdown strength leading to a high actuated strain. Adding a plasticizer into the dielectric elastomer decreased the dielectric constant and electrical breakdown strength slightly, but reduced the elastic modulus sharply, which was beneficial for obtaining a large strain at low electric field from the dielectric elastomer. The largest actuated strain of 22% at an electric field of 30 kV mm −1 without any prestrain was obtained. Moreover, the hydrogenated nitrile–butadiene dielectric actuator showed good history dependence. This proposed material has great potential to be an excellent dielectric elastomer. (paper)

2018-01-01

Ultrasonography has been widely employed to estimate the morphological changes of muscle during contraction. To further investigate the motion pattern of quadriceps during isometric knee extensions, we studied the relative motion pattern between femur and quadriceps under ultrasonography. An interesting observation is that although the force of isometric knee extension can be controlled to change almost linearly, femur in the simultaneously captured ultrasound video sequences has several different piecewise moving patterns. This phenomenon is like quadriceps having several forward gear ratios like a car starting from rest towards maximal voluntary contraction (MVC) and then returning to rest. Therefore, to verify this assumption, we captured several ultrasound video sequences of isometric knee extension and collected the torque/force signal simultaneously. Then we extract the shapes of femur from these ultrasound video sequences using video processing techniques and study the motion pattern both qualitatively and quantitatively. The phenomenon can be seen easier via a comparison between the torque signal and relative spatial distance between femur and quadriceps. Furthermore, we use cluster analysis techniques to study the process and the clustering results also provided preliminary support to the conclusion that, during both ramp increasing and decreasing phases, quadriceps contraction may have several forward gear ratios relative to femur.

[Ethical aspects of disclosing information on prenatal screening for Down's syndrome].

Science.gov (United States)

Tóth, Adél; Szabó, János

2005-02-06

Giving detailed information on prenatal screening for Down's syndrome is considered as paramount since this medical procedure intends to enhance the patient's self-governance in reproductive issues. Not only the respect for autonomy, but also the increased maternal anxiety and the reproductive decisions following the positive test result demand from the genetic professional to offer the test through genetic counselling. The counsellor's awareness about the expectations of pregnant women and the clarification of her own attitude concerning the screening can contribute to the effectiveness of counselling. The content of information embraces the technical aspects of screening and its consequences, like the description of Down's syndrome, the method of screening, the way of risk assessment, the detection rate, the false positive and false negative test results, the diagnostic procedures, and the termination of pregnancy. Written information leaflets should be completed by personal communication as the combination of these two forms has proved to be the most useful. The process of consultation is influenced by the communication skill of the genetic professional and the information seeking activity of the patient, so doctors should be trained to communicate better and patients should be encouraged to get more information about the screening.

Background Delayed disclosure of rape has been associated with impaired mental health; it is, therefore, important to understand which factors are associated with disclosure latency. The purpose of this study was to compare various demographics, post-rape characteristics, and psychological functioning of early and delayed disclosers (i.e., more than 1-week post-rape) among rape victims, and to determine predictors for delayed disclosure. Methods Data were collected using a structured interview and validated questionnaires in a sample of 323 help-seeking female adolescents and young adults (12–25 years), who were victimized by rape, but had no reported prior chronic child sexual abuse. Results In 59% of the cases, disclosure occurred within 1 week. Delayed disclosers were less likely to use medical services and to report to the police than early disclosers. No significant differences were found between delayed and early disclosers in psychological functioning and time to seek professional help. The combination of age category 12–17 years [odds ratio (OR) 2.05, confidence intervals (CI) 1.13–3.73], penetration (OR 2.36, CI 1.25–4.46), and closeness to assailant (OR 2.64, CI 1.52–4.60) contributed significantly to the prediction of delayed disclosure. Conclusion The results point to the need of targeted interventions that specifically encourage rape victims to disclose early, thereby increasing options for access to health and police services.

Objectives: The objectives of the study were to determine knowledge, attitudes, and practices of HIV-positive patients regarding the disclosure of HIV status at Betesda Clinic in Namibia, and to determine the reasons for disclosure and non-disclosure. Methods: This was a cross-sectional descriptive study and 263 HIV-positive patients were enrolled in the study. Results: Analyses revealed that knowledge on disclosure was good, with 68% who thought it was important. The majority (73% have disclosed and 60% disclosed within 1 week of receiving their results. The most common reasons for disclosure were that 32% needed help, 25% wanted his or her partner to go for testing, and 20% wanted to let relatives know. Reasons for non-disclosure were mainly the fear of gossip (79%. Seventy-three per cent had disclosed to their partners, and 23% had disclosed to more than one person. People’s reactions were supportive in 43%, whereas 29% understood, 9% accepted and 6% were angry. Upon disclosure 40% received help, 24% of partners were tested, 23% received psychological support and 5% were stigmatised. Disclosure was higher amongst the married and cohabitating. Conclusion: The attitude was positive with regard to knowledge of disclosure, with most participants thinking that disclosure was important and good. The attitudes and actual practices of disclosure were encouraging; however, people are disclosing only to trusted individuals in the society and the fear of stigma is still present although the actual stigma was very low.

Behavior learning in differential games and reorientation maneuvers

Science.gov (United States)

Satak, Neha

method is the Direct Approximation of Value Function (DAVF) method. In this method, unlike the CSR method, the player formulates an objective function for the opponent but does not formulates a strategy directly; rather, indirectly the player assumes that the opponent is playing optimally. Thus, a value function satisfying the HJB equation corresponding to the opponent's cost function exists. The DAVF method finds an approximate solution for the value function based on previous observations of the opponent's control. The approximate solution to the value function is then used to predict the opponent's future behavior. Game examples in which only a single player is learning its opponent's behavior are simulated. Subsequently, examples in which both players in a two-player game are learning each other's behavior are simulated. In the second part of this research, a reorientation control maneuver for a spinning spacecraft will be developed. This will aid the application of behavior learning and differential games concepts to the specific scenario involving multiple spinning spacecraft. An impulsive reorientation maneuver with coasting will be analytically designed to reorient the spin axis of the spacecraft using a single body fixed thruster. Cooperative maneuvers of multiple spacecraft optimizing fuel and relative orientation will be designed. Pareto optimality concepts will be used to arrive at mutually agreeable reorientation maneuvers for the cooperating spinning spacecraft.

Key Performance Indicators Disclosures Through Internet: towards an integrated scoreboard

Ilídio Tomás Lopes

2014-10-01

Full Text Available Purpose – Information disclosure is driven by multiple determinants, most of them supported by traditional theories, such as agency theory, contingency theory, and legitemacy theory. This research aims to identify a set of Key Performance Indicators (KPI, disclosed to stakeholders through Internet. It also aims to apply for an integrated performance scorebord, acting it as a dynamic comparative tool, in particular for listed companies which market value is driven by investors expectations and needs.Design/methodology/approach – Based on 47 listed companies from the Portuguese Stock Index regulated market, and through an interpretive content analysis, research was driven towards the identification of KPI that were explicitly reported to stakeholders through structured or unstructured frameworks. This qualitative approach supports the evidences about performance indicators reported by listed companies to stakeholders, in particular to potential stockholders.Findings – Companies disclose a wide variety of key performance indicators, however in most cases included in their periodical management reports. Only a low number of companies disclose those indicators through a visible form in their web sites. Furthermore, KPI disclosed have a generic nature and are usually complemented by theoretical explanations about their evolution and trends. The diversity of indicators disclosed does not permit a comparision between companies and activity sectors. Key performence indicators are still disclosed on a voluntarily basis, remaining, in this scope, multiple agency conflicts and other issues around agency costs. Altough the intensity and categorization in the information disclosure, a standard framework is required in orther to ensure a dynamic comparision between companies or sectors.   Research limitations – The scope of this research is the Portuguese regulated market. Further research can introduce in the sample companies listed in other

Kooienga, Sarah; Stewart, Valerie T

2011-01-01

Knowledge of the patient's perspective on medical error is limited. Research efforts have centered on how best to disclose error and how patients desire to have medical error disclosed. On the basis of a qualitative descriptive component of a mixed method study, a purposive sample of 30 community members told their stories of medical error. Their experiences focused on lack of communication, missed communication, or provider's poor interpersonal style of communication, greatly contrasting with the formal definition of error as failure to follow a set standard of care. For these participants, being a patient was more important than error or how an error is disclosed. The patient's understanding of error must be a key aspect of any quality improvement strategy. © 2010 National Association for Healthcare Quality.

Discussions regarding disclosure of funding sources and conflicts of interest (COI) in published peer-reviewed journal articles are becoming increasingly more common and intense. The aim of the present study was to examine whether randomized controlled trials (RCTs) published in leading surgery journals report funding sources and COI. All articles reporting randomized controlled phase III trials published January 2005 through December 2010 were chosen for review from ten international journals. We evaluated the number of disclosed funding sources and COI, and the factors associated with such disclosures. From a review of 657 RCT from the ten journals, we discovered that presence or absence of a funding source and COI was disclosed by 47 % (309) and 25.1 % (165), respectively. Most articles in "International Committee of Medical Journal Editors (ICMJE)-affiliated journals" did not disclose COI. Disclosure of funding was associated with a journal impact factor >3 (51.7 vs 41.6 %; p funding sources (i.e., whether or not there was a funding source), and almost three quarters did not disclose whether COI existed. Our findings suggest the need to adopt best current practices regarding disclosure of competing interests to fulfill responsibilities to readers and, ultimately, to patients.

Disclosure of HIV serostatus among pregnant and postpartum women in sub-Saharan Africa: a systematic review.

Tam, Melanie; Amzel, Anouk; Phelps, B Ryan

2015-01-01

Disclosure of one's HIV status can help to improve uptake and retention in prevention of mother-to-child transmission of HIV services; yet, it remains a challenge for many women. This systematic review evaluates disclosure rates among pregnant and postpartum women in sub-Saharan Africa, timing of disclosure, and factors affecting decisions to disclose. PubMed and EMBASE databases were searched to identify relevant studies published between January 2000 and April 2014. Rates of HIV serostatus disclosure to any person ranged from 5.0% to 96.7% (pooled estimate: 67.0%, 95% CI: 55.7%-78.3%). Women who chose to disclose their status did so more often to their partners (pooled estimate: 63.9%; 95% CI: 56.7%-71.1%) than to family members (pooled estimate: 40.1; 95% CI: 26.2%-54.0%), friends (pooled estimate: 6.4%; 95% CI: 3.0%-9.8%), or religious leaders (pooled estimate: 7.1%; 95% CI: 4.3%-9.8%). Most women disclosed prior to delivery. Decisions to disclose were associated with factors related to the woman herself (younger age, first pregnancies, knowing someone with HIV, lower levels of internalized stigma, and lower levels of avoidant coping), the partner (prior history of HIV testing and higher levels of educational attainment), their partnership (no history of domestic violence and financial independence), and the household (higher quality of housing and residing without co-spouses or extended family members). Interventions to encourage and support women in safely disclosing their status are needed.

The aim of this study was to explore the acceptability of antenatal enquiry for domestic abuse from the perspective of women using maternity services. It also sought to understand the experiences of referral and support offered to women who had positively disclosed abuse. A multimethod approach was adopted including quantitative and qualitative elements. The survey assessed women's views of the acceptability and impact of routine enquiry for domestic abuse. Interviews aimed, to understand the views and experiences of women who had positively disclosed abuse during their contact with maternity services. 94.4% of those surveyed felt comfortable with a midwife asking about abuse. 96.6% of the participants also believed it was appropriate for a midwife to ask and that midwives should be able to respond to positive disclosure. Interviewees subject to abuse during pregnancy were happy to be questioned, even though they did not always feel able to disclose immediately. Women had a positive view of antenatal enquiry for domestic abuse in healthcare settings and support its continuation. Women expect to be asked and that midwives can respond appropriately. Raising the issue creates a culture in which women are made aware of the impact of abuse and understand there are avenues of support even if she decides not to leave the relationship. Women may choose not to disclose about the abuse at the initial time of asking, for fear of their own safety but asking signifies that she can disclose about at a later contact. © 2013 Blackwell Publishing Ltd.

Ionising radiation risk disclosure: When should radiographers assume a duty to inform?

Science.gov (United States)

Younger, C W E; Douglas, C; Warren-Forward, H

2018-05-01

Autonomy is a fundamental patient right for ethical practice, and informed consent is the mechanism by which health care professionals ensure this right has been respected. The ethical notion of informed consent has evolved alongside legal developments. Under Australian law, a provider who fails to disclose risk may be found to be in breach of a duty of disclosure, potentially facing legal consequences if the patient experiences harm that is attributable to an undisclosed risk. These consequences may include the common law tort of negligence. Ionising radiation, in the form of a medical imaging examination, has the potential to cause harm. However, stochastic effects cannot be attributable to a specific ionising radiation event. What then is the role of the Australian medical imaging service provider in disclosing ionising radiation risk? The ethical and legal principles of informed consent, and the duty of information provision to the patient are investigated. These general principles are then applied to the specific and unusual case of ionising radiation, and what responsibilities apply to the medical imaging provider. Finally, the legal, professional and ethical duties of the radiographer to disclose information to their patients are investigated. Australian law is unclear as to whether a radiographer has a common law responsibility to disclose radiation risk. There is ambiguity as to whether stochastic ionising radiation risk could be considered a legal disclosure responsibility. While it is unlikely that not disclosing risk will have medicolegal consequences, doing so represents sound ethical practice. Copyright © 2017 The College of Radiographers. Published by Elsevier Ltd.

Disclosure of HIV status supports risk reduction and facilitates access to prevention and care services, but can be inhibited by the fear of negative repercussions. We explored the short and long-term outcomes of disclosure among clients attending an urban HIV clinic in Uganda. Qualitative semi-structured interviews were administered to a purposeful sample of 40 adult HIV clients that was stratified by gender. The information elicited included their lived experiences and outcomes of disclosure in the short and long term. A text data management software (ATLAS.ti) was used for data analysis. Codes were exported to MS Excel and pivot tables, and code counts made to generate statistical data. Of the 134 short-term responses elicited during the interview regarding disclosure events, most responses were supportive including encouragement, advice and support regarding HIV care and treatment. The results show on-disclosing to spouse, there was more trust, and use of condoms for HIV prevention. Only one third were negative responses, like emotional shock and feeling of distress. The negative reactions to the spouses included rejection, shock and distress in the short term. Even then, none of these events led to drastic change such as divorce. Other responses reflected HIV prevention and call for behavioural change and advice to change sexual behaviour, recipient seeking HIV testing or care. Women reported more responses of encouragement compared to men. Men reported more preventive behaviour compared to women. Of the 137 long-term outcomes elicited during disclosure, three quarters were positive followed by behavioral change and prevention, and then negative responses. Men reported increased care and support when they disclosed to fellow men compared to when women disclosed to women. There was better or not change in relationship when women disclosed to women than when women disclosed to men. There is overwhelming support to individuals that disclose their HIV status

HIV status disclosure is a difficult emotional task for HIV-infected persons and may create the opportunity for both social support and rejection. In this study, we evaluated the proportions, patterns, barriers and outcomes of HIV- 1 status disclosure among a group of women in Uganda. An exit interview was conducted one year post-partum for 85 HIV-infected women who participated in a study of HIV-1 transmission rates among NVP-experienced compared with NVP-naïve women in "The Nevirapine Repeat Pregnancy (NVP-RP) Study" at the Makerere University-Johns Hopkins University Research Collaboration, Kampala-Uganda, between June 2004 and June 2006. Of the 85 women interviewed, 99 % had disclosed their HIV status to at least one other person. Disclosure proportions ranged between 1 % to employer(s) and 69 % to a relative other than a parent. Only 38 % of the women had disclosed to their sex partners. Women with an HIV-infected baby were more likely than those with an uninfected baby to disclose to their sex partner, OR 4.9 (95 % CI, 2.0 -11.2), and women were less likely to disclose to a partner if they had previously disclosed to another relative than if they had not, OR 0.19 (95 % CI, 0.14-0.52). The most common reasons for non-disclosure included fear of separation from the partner and subsequent loss of financial support 34 %, and not living with the partner (not having opportunities to disclose) 26 %. While most women (67 %) reported getting social support following disclosure, 22 % reported negative outcomes (neglect, separation from their partners, and loss of financial support). Following disclosure of HIV status, 9 % of women reported that their partner (s) decided to have an HIV test. Results from this study show high overall HIV disclosure proportions and how this disclosure of HIV status can foster social support. However, proportions of disclosure specifically to male sex partners were low, which suggests the need for interventions aimed at increasing male

Octahedral molecular sieve sorbents and catalysts are disclosed, including silver hollandite and cryptomelane. These materials can be used, for example, to catalyze the oxidation of CO.sub.x (e.g., CO), NO.sub.x (e.g., NO), hydrocarbons (e.g., C.sub.3H.sub.6) and/or sulfur-containing compounds. The disclosed materials also may be used to catalyze other reactions, such as the reduction of NO.sub.2. In some cases, the disclosed materials are capable of sorbing certain products from the reactions they catalyze. Silver hollandite, in particular, can be used to remove a substantial portion of certain sulfur-containing compounds from a gas or liquid by catalysis and/or sorption. The gas or liquid can be, for example, natural gas or a liquid hydrocarbon.

To describe what and why nurses self-disclose to patients in mental health care. Self-disclosure is common, but controversial and difficult to delineate. Extant research suggests that self-disclosure might have several potentially beneficial effects on therapeutic alliance and treatment outcome for patients in mental health care, but results are often mixed and limited by definitional inconsistencies. Multi-site study with purposive sampling and source triangulation. Qualitative descriptive study including data from 16 nurses taking part in participant observation, individual interviews and focus group interviews. Separate analyses resulted in four themes addressing the research question of what nurses self-disclose, and one main theme and four subthemes addressing why nurses self-disclose. The content of self-disclosure was captured in the four themes: Immediate family, Interests and activities, Life experiences and Identity. In addition, results showed that disclosures were common among the nurses. Self-disclosure's potential to transform the nurse-patient relationship, making it more open, honest, close, reciprocal and equal, was the overarching reason why nurses shared personal information. The nurses also chose to self-disclose to share existential and everyday sentiments, to give real-life advice, because it felt natural and responsive to patients' question to do so. Nurse self-disclosure is common and cover a variety of personal information. Nurses have several reasons for choosing to self-disclose, most of which are connected to improving the nurse-patient relationship. Self-disclosure controversy can make it difficult for nurses to know whether they should share personal information or not. Insights into the diversity of and reasons for nurse self-disclosure can help with deliberations on self-disclosure. © 2017 John Wiley & Sons Ltd.

To evaluate the effectiveness of mobile phones in enhancing self-care, adjustment and engagement in non-disclosed youth living with HIV. Youth aged 15-24 years represent 42% of new HIV infections globally. Youth who are aware of their HIV status generally do not disclose it or utilize HIV-related facilities because of fear of stigma. They rely on the Internet for health maintenance information and access formal care only when immune-compromised and in crisis. This study shows how non-disclosed youth living with HIV can be reached and engaged for self-management and adjustment through mobile phone. One-group pre-test/post-test experimental design was used. Mobile phones were used to give information, motivation and counselling to 19 purposively recruited non-disclosed youth with HIV in Calabar, South-South Nigeria. Psychological adjustment scale, modified self-care capacity scale and patient activation measure were used to collect data. Data were analysed using PASW 18.0. Scores on self-care capacity, psychological adjustment and engagement increased significantly at post-test. HIV-related visits to health facilities did not improve significantly even at 6 months. Participants still preferred to consult healthcare providers for counselling through mobile phone. Mobile phone-based interventions are low cost, convenient, ensure privacy and are suitable for youth. Such remote health counselling enhances self-management and positive living. Mobile phones enhance self-care, psychological adjustment and engagement in non-disclosed youth living with HIV, and can be used to increase care coverage. Findings underline the importance of policies to increase access by locating, counselling and engaging HIV-infected youth in care. © 2016 International Council of Nurses.

Human Immunodeficiency Virus (HIV) status disclosure has been shown to provide several benefits, both at the individual and societal levels. To determine risk factors associated with disclosing HIV status among antiretroviral therapy (ART) recipients in South Africa. A cross-sectional study on risk factors for viremia and drug resistance took place at two outpatient HIV clinics in 2008, at a large hospital located in Soweto, South Africa. We conducted a secondary data analysis on socio-economic characteristics and HIV status disclosure to anyone, focusing on gender differences. Descriptive and multivariable logistic regression analyses were performed to model the associations between risk factors and HIV status disclosure. Additionally, descriptive analysis was conducted to describe gender differences of HIV status disclosure to partner, parents, parents in law, partner, child, family, employer, and other. A total of 883 patients were interviewed. The majority were women (73%) with median age of 39 years. Employed patients were less likely to disclose than unemployed (odds ratio (OR) 0.36; 95% confidence interval (CI) 0.1-1.0; p = 0.05)). Women with higher income were more likely to disclose (OR 3.25; 95% CI 0.90-11.7; p = 0.07) than women with lower income, while men with higher income were less likely (OR 0.20; 95% CI 0.02-1.99; p = 0.17) than men with lower income. Men were more likely than women to disclose to their partner (pwomen were more likely than men to disclose to child and family (pgender and income on disclosure. Interventions designed to reduce workplace discrimination and gender-sensitive interventions promoting disclosure are strongly recommended.

Discordance exists between author self-disclosure and the Open Payments Database in various surgical fields, but the effects of this discordance on study design and presentation are unknown. We hypothesized that, among ventral hernia publications, discordance exists between industry and physician self-reported conflicts of interest (COIs); authors disclose relevant COIs; and disclosure and relevant COIs affect study favorability. We conducted a double-blinded, prospective, observational study of published articles. PubMed was searched in reverse chronological order for clinical articles pertaining to ventral hernias. Authors' self-disclosed conflicts were compared with those on the Open Payments Database. Two reviewers blinded to article disclosure status determined jointly whether the COIs were relevant to the article. Three blinded referees independently voted whether each article was favorable to discussed subject matter. The primary end point was study favorability. Secondary outcomes included disclosure status and relevance. One hundred articles were included. Compared with authors with no COIs, authors with a COI, self-disclosed or not, were twice as likely to write results favorable to industry. Of those with a COI, most of the articles had a relevant COI (37 of 45 [82.2%]), and 25% of relevant COIs were not disclosed by authors. Among authors with a relevant COI, study favorability remained unchanged at 68.5% (control: no COI 33.3%; p reporting of COI is discordant in 63% of articles. Twenty-five percent of relevant COI are not disclosed. Having a COI increases the chances that an article will cast a favorable impression on the company paying the authors by 200%.

Full Text Available Background: This study examined the practices, knowledge, attitudes, and the reasons for disclosure and non-disclosure of HIV-positive patients with regard to the disclosure of HIV results at Betesda Clinic in Windhoek, Namibia.Objectives: The objectives of the study were to determine knowledge, attitudes, and practices of HIV-positive patients regarding the disclosure of HIV status at Betesda Clinic in Namibia, and to determine the reasons for disclosure and non-disclosure.Methods: This was a cross-sectional descriptive study and 263 HIV-positive patients were enrolled in the study.Results: Analyses revealed that knowledge on disclosure was good, with 68% who thought it was important. The majority (73% have disclosed and 60% disclosed within 1 week of receiving their results. The most common reasons for disclosure were that 32% needed help, 25% wanted his or her partner to go for testing, and 20% wanted to let relatives know. Reasons for non-disclosure were mainly the fear of gossip (79%. Seventy-three per cent had disclosed to their partners, and 23% had disclosed to more than one person. People’s reactions were supportive in 43%, whereas 29% understood, 9% accepted and 6% were angry. Upon disclosure 40% received help, 24% of partners were tested, 23% received psychological support and 5% were stigmatised. Disclosure was higher amongst the married and cohabitating.Conclusion: The attitude was positive with regard to knowledge of disclosure, with most participants thinking that disclosure was important and good. The attitudes and actual practices of disclosure were encouraging; however, people are disclosing only to trustedindividuals in the society and the fear of stigma is still present although the actual stigma was very low.

Global prize-based science contests have great potential for tapping into diverse knowledge on a global scale and overcoming important scientific challenges. A necessary step for knowledge to be utilized in these contests is for that knowledge to be disclosed. Knowledge disclosure, however, is paradoxical in nature: in order for the value of knowledge to be assessed, inventors must disclose their knowledge, but then the person who receives that knowledge does so at no cost and may use it opportunistically. This risk of potential opportunistic behavior in turn makes the inventor fearful of disclosing knowledge, and this is a major psychological barrier to knowledge disclosure. In this project, we investigated this fear of opportunism in global prize-based science contests by surveying 630 contest participants in the InnoCentive online platform for science contests. We found that participants in these science contests experience fear of opportunism to varying degrees, and that women and older participants have significantly less fear of disclosing their scientific knowledge. Our findings highlight the importance of taking differences in such fears into account when designing global prize-based contests so that the potential of the contests for reaching solutions to important and challenging problems can be used more effectively.

Background Anti-stigma programmes should aim to increase disclosure to those who can support someone with a mental health problem and appropriate professional help-seeking. Aims We investigated associations among public awareness of England's Time to Change anti-stigma campaign and: (a) comfort envisaged in disclosing a mental health problem to family and friends; (b) comfort in disclosing to an employer; and (c) intended professional help-seeking from a general practitioner, i.e. a physician working in primary care. Method Using data from a survey of a nationally representative sample of adults, we created separate logistic regression models to test for campaign awareness and other variables as predictors of comfort in disclosure and intended help-seeking. Results We found positive relationships between campaign awareness and comfort in disclosing to family and friends (odds ratio (OR) = 1.27, 95% CI 1.14-1.43) and to a current or prospective employer (OR=1.20, 95% CI 1.06-1.35); and likelihood of help-seeking (OR=1.18 95% CI 1.03-1.36). Conclusions Awareness of an anti-stigma campaign was associated with greater comfort in disclosing a mental health problem and intended help-seeking. © The Royal College of Psychiatrists 2017.

Full Text Available This paper tackles the difficult and often not openly discussed This paper tackles the difficult and often not openly discussed topic of access and equity in higher education for people with mental health difficulties. Recent legislative and policy developments in mental health, disability, anti-discrimination and education mean that all students who disclose a mental health condition can expect fair and equitable treatment. However the findings of an exploratory study at an Australian university reveal that just under two thirds of the 54 students who reported mental health difficulties did not disclose this to staff due to fears of discrimination at university and in future employment. Students who did disclose felt supported when staff displayed a respectful attitude and provided appropriate advice and useful strategies for them to remain engaged in university studies when experiencing mental health difficulties.

Disclosing and concealing: internet governance, information control and the management of visibility

Directory of Open Access Journals (Sweden)

Mikkel Flyverbom

2016-09-01

Full Text Available The ubiquity of digital technologies and the datafication of many domains of social life raise important questions about governance. In the emergent field of internet governance studies, most work has explored novel governance arrangements, institutional developments and the effects of interactions among public and private actors in the emergence of the internet as a matter of concern in global politics. But the digital realm involves more subtle forms of governance and politics that also deserve attention. In this paper, I suggest that the 'ordering' effects of digital infrastructures also revolve around what I term the ‘management of visibilities’. Drawing on insights from science and technology studies and sociologies of visibility, the paper articulates how digital technologies afford and condition ordering through the production of visibilities and the guidance of attention. The basic tenet of the argument is that there is an intimate relationship between seeing, knowing and governing, and that digitalisation and datafication processes fundamentally shape how we make things visible or invisible, knowable or unknowable and governable or ungovernable. Having articulated this conceptual argument, the article offers a number of illustrations of such forms of ordering.

Log Usage Analysis: What it Discloses about Use, Information Seeking and Trustworthiness

Directory of Open Access Journals (Sweden)

David Nicholas

2014-06-01

Full Text Available The Trust and Authority in Scholarly Communications in the Light of the Digital Transition research project1 was a study which investigated the behaviours and attitudes of academic researchers as producers and consumers of scholarly information resources in respect to how they determine authority and trustworthiness. The research questions for the study arose out of CIBER’s studies of the virtual scholar. This paper focuses on elements of this study, mainly an analysis of a scholarly publisher’s usage logs, which was undertaken at the start of the project in order to build an evidence base, which would help calibrate the main methodological tools used by the project: interviews and questionnaire. The specific purpose of the log study was to identify and assess the digital usage behaviours that potentially raise trustworthiness and authority questions. Results from the self-report part of the study were additionally used to explain the logs. The main findings were that: 1 logs provide a good indicator of use and information seeking behaviour, albeit in respect to just a part of the information seeking journey; 2 the ‘lite’ form of information seeking behaviour observed in the logs is a sign of users trying to make their mind up in the face of a tsunami of information as to what is relevant and to be trusted; 3 Google and Google Scholar are the discovery platforms of choice for academic researchers, which partly points to the fact that they are influenced in what they use and read by ease of access; 4 usage is not a suitable proxy for quality. The paper also provides contextual data from CIBER’s previous studies.

The aim of preventive follow-up examinations of former employees of the concern Czechoslovak Uranium Mines is to determine possible health damage of chronically exposed workers in an area that can become manifest even following a long time after leaving the high-risk working environment. In a group of 1,139 persons that had undergone preventive follow-up examinations in the years 1977 to 1980 there were 63 cases of newly detected affections that were reported as occupational diseases, and other serious affections. The system of preventive follow-up examinations represents a significant contribution to the improvement of health care of the workers. (author)

2014-01-01

Few studies have fully explored the problem of communication barriers in pediatric palliative care, particularly the detrimental effects of poor interaction between staff and families on children's health and well-being. A literature review was undertaken to expand the current body of knowledge about staff to patient communications. Articles meeting the inclusion criteria (N = 15) were systematically read and summarized using a data extraction sheet. A narrative synthesis identified 5 overarching themes as barriers to communication. Improvements in staff education and individualized palliative care plans for children and their families may help to overcome communication barriers.

Why You Go Reveals Who You Know: Disclosing Social Relationship by Cooccurrence

Directory of Open Access Journals (Sweden)

Feng Yi

2017-01-01

Full Text Available The popularity of location-based services (LBS and the ubiquity of sensor device have resulted in rich spatiotemporal data. A large number of human behaviors had been recorded including cooccurrence which refers to the phenomenon that two people have been to the same places at the same time. These data enable attackers to infer people’s social relationship based on their cooccurrences and many attack models were proposed. However, current attack models still cannot effectively address the following two challenges: How to distinguish cooccurrences between acquaintances and strangers? What kind of cooccurrence contributes to strong social strength? In this paper, we present a novel social relationship attack model—the Mobility Intention-based Relationship Inference (MIRI model—which can solve the above two issues. Firstly, we extract mobility intentions and adopt them to characterize cooccurrences. A classification model is trained for attacking social relationship. The experimental results on two real-world datasets demonstrate that the proposed MIRI model can properly differentiate cooccurrences by simultaneously considering spatial and temporal features. The comparison results also indicate that MIRI model significantly outperforms state-of-the-art social relationship attack models.

Flying at no mechanical energy cost: disclosing the secret of wandering albatrosses.

Directory of Open Access Journals (Sweden)

Gottfried Sachs

Full Text Available Albatrosses do something that no other birds are able to do: fly thousands of kilometres at no mechanical cost. This is possible because they use dynamic soaring, a flight mode that enables them to gain the energy required for flying from wind. Until now, the physical mechanisms of the energy gain in terms of the energy transfer from the wind to the bird were mostly unknown. Here we show that the energy gain is achieved by a dynamic flight manoeuvre consisting of a continually repeated up-down curve with optimal adjustment to the wind. We determined the energy obtained from the wind by analysing the measured trajectories of free flying birds using a new GPS-signal tracking method yielding a high precision. Our results reveal an evolutionary adaptation to an extreme environment, and may support recent biologically inspired research on robotic aircraft that might utilize albatrosses' flight technique for engineless propulsion.

Mulheres vivendo com aids e os profissionais do Programa Saúde da Família: revelando o diagnóstico Mujeres viviendo con sida y los profesionales del programa salud de la família: revelando el diagnóstico Women living with aids and the family health program professionals: disclosing the diagnosis

Directory of Open Access Journals (Sweden)

Fernanda Cristina Ferreira

2008-09-01

study was carried out with women living with HIV/AIDS cared by a specialized STD/AIDS service and registered in a Family Health Program (FHP unit. The purpose was to identify the motivations of women living with HIV/AIDS to provide private information to the FHP team. The study was performed using semi-structured interviews, analyzed with the bioethics theoretical framework. It was verified that women disclose the diagnosis to the FHP team when: the HIV/AIDS diagnosis was made in the unit; they feel there is better treatment for being HIV positive; they are bond as family members; there is trust; and women feel that they do not feel pity of them. Women so not disclose when: the professional's attitude produces fear and unreliability; they think that the FHP takes care of bedridden patients; they do not trust by fearing secret disclosure; and they already have all the care needed in the SCS.

Herpes simplex virus: 'to disclose or not to disclose.' An exploration of the multi-disciplinary team's role in advising patients about disclosure when diagnosed with genital herpes simplex virus.

Science.gov (United States)

Caulfield, Pauline; Willis, Diane

2017-07-01

The first UK prosecution for genital herpes simplex virus (HSV) transmission in 2011 attracted strong criticism from medical experts. To address the dearth of research on the topic, this study aimed to explore the nature of advice given to patients by the multidisciplinary team (MDT) in the West of Scotland on HSV disclosure to partners. Ten semi-structured interviews with members of the MDT were conducted and the interviews were analysed using Burnard's Thematic Content Analysis. Four themes emerged which explored practitioners' knowledge of HSV and their feelings regarding the emotional aspects of the diagnosis on clients including the challenges of discussing disclosure. Within this framework, participants' attitudes to the legal prosecution were also surveyed. This study revealed that participants had good knowledge about HSV. Furthermore, participants believed disclosure to be the patient's choice and had not altered their practice to advise disclosure to all partners in accordance with local protocol. However, there was a general consensus that disclosure was not required due to the prevalence of HSV and prevalence was used to dissipate emotional reactions to HSV diagnosis.

Blake, L; Casey, P; Readings, J; Jadva, V; Golombok, S

2010-10-01

The present study explored the process of disclosure in gamete donation families in the UK. Interviews were conducted with 23 mothers and 15 fathers who had told their 7-year-old child about the nature of their conception. Twelve children were interviewed about what they understood and how they felt about their donor conception (DC). The majority of families had disclosed by the age of four and mothers were found to be the main disclosers. Although some parents expressed concerns about the disclosure, the majority did not experience difficulties. No child responded to disclosure in a negative way. Seven-year-old children showed little understanding of their DC, despite parents starting the process of disclosure before the age of four. In spite of mothers' concerns about disclosing DC to their children, children responded to disclosure in a neutral way and most parents did not find disclosure to be problematic.

Disclosure indices design: does it make a difference?

Directory of Open Access Journals (Sweden)

Francisco Bravo Urquiza

2009-07-01

Full Text Available Measurement of information disclosed by companies is a complex task. Accounting research usually relies on disclosure indices to obtain a proxy for the information disclosed by companies. However, there is no consensus about the best design for these indices. The purpose of this paper is to investigate if there are significant differences among the indices that are used in disclosure studies. Three indices that measure disclosure of forward-looking information are compared: A “quality index” of a multidimensional nature; a “scope index” designed specifically to measure the scope of information, and a “quantity index” that measures information disclosed exclusively in terms of quantity. Results of the empirical analysis indicate that although the indices are correlated, they have a big impact in the rankings of companies. Evidence against the idea of the irrelevance of the particular index chosen is provided.

Medical confidentiality versus disclosure: Ethical and legal dilemmas.

LENUS (Irish Health Repository)

Agyapong, V I O

2009-02-01

A case is described of a fifty year old single man who made disclosures about criminal sexual practices during a psychiatric assessment. In common practice with other professional men, a doctor is under a duty not to disclose, without the consent of his patient, information which he has gained in his professional capacity other than in exceptional circumstances. We discuss the ethical and legal considerations surrounding issues of medical confidentiality and the dilemma that sometimes face clinicians, when they feel obliged, in the public interest, to disclose information they have gained in confidence. Breach of confidences can have deleterious consequences; particularly for the doctor-patient relationship, but failure to disclose in some situations could have serious implications for the well-being of the wider society. Doctors should be aware of the basic principles of confidentiality and the ethical and legal framework around which they are built.

2016-01-01

To identify opportunities for disclosing information on medical errors in Spain and issuing an apology, as well as legal-ethical barriers. A cross-sectional study was conducted through a questionnaire sent to health law and bioethics experts (n=46). A total of 39 experts (84.7%) responded that health providers should always disclose adverse events and 38 experts (82.6%) were in favour of issuing an apology. Thirty experts (65.2%) reported that disclosure of errors would not lead to professional liability. The main opportunity for increasing disclosure was by enhancing trust in the physician-patient relationship and the main barrier was fear of the outcomes of disclosing medical errors. There is a broad agreement on the lack of liability following disclosure/apology on adverse events and the need to develop a strategy for disclosure among support for physicians.

Baker, Amira Noori; Bayer, Angela Marie; Kolevic, Lenka; Najarro, Lizzete; Viani, Rolando Mario; Deville, Jaime Gerardo

2018-01-01

Despite recommendations for disclosure of HIV status to children living with HIV (CLHIV), fewer than half of CLHIV at the Instituto Nacional de Salud del Niño (INSN) in Lima, Peru, have had disclosure. How and when the disclosure process for CLHIV should take place in Peru has not been studied. We conducted a qualitative study at INSN to explore perceptions and experiences of 6 health care providers (HCPs), 14 disclosed and nondisclosed CLHIV (8-17 years), and their 14 caregivers regarding knowledge of illness, disclosure of HIV status, and appropriate disclosure approaches. Disclosed children wanted to be told their diagnosis earlier. Nondisclosed children expressed frustration taking medications. Caregivers and HCPs discussed motivations to disclose, including educating, honesty, improving medication adherence, and preventing secondary transmission. Culturally appropriate guidelines and training for HCPs and caregivers are needed to support disclosure of children's HIV status and ongoing support for CLHIV.

Adolescents living with HIV (ALHIV) face many psychosocial challenges, including HIV disclosure to others. Given the importance of socialization during the adolescent transition process, this study investigated the psychological and social factors influencing self-disclosure of own HIV status to peers. We examined social HIV self-disclosure to peers, and its relationship to perceived HIV-related stigma, self-efficacy to disclose, self-esteem, and social support among a sample of n = 582 ALHIV aged 13-17 years in Kampala, Uganda, and Western Kenya. Data were collected between February and April 2011. Among them, 39% were double orphans. We conducted a secondary data analysis to assess the degree of social disclosure, reactions received, and influencing factors. Interviewer-administered questionnaires assessed medical, socio-demographic, and psychological variables (Rosenberg self-esteem scale; self-efficacy to disclose to peers), HIV-related stigma (10-item stigma scale), and social support (family-life and friends). Descriptive, bivariate, and logistic regression analyses were performed with social self-disclosure to peers with gender as covariates. Almost half of ALHIV had told nobody (except health-care providers) about their HIV status, and about 18% had disclosed to either one of their friends, schoolmates, or a boy- or girlfriend. Logistic regression models revealed that having disclosed to peers was significantly related to being older, being a paternal orphan, contributing to family income, regular visits to the HIV clinic, and greater social support through peers. Low self-efficacy to disclose was negatively associated to the outcome variable. While social self-disclosure was linked to individual factors such as self-efficacy, factors relating to the social context and adolescents' access to psychosocial resources play an important role. ALHIV need safe environments to practice disclosure skills. Interventions should enable them to make optimal use of

The 2007 United Nations General Assembly Report on HIV/AIDS in Zimbabwe reported nondisclosure of HIV status as a challenge in the PMTCT programme. Preliminary investigations on nondisclosure among 21 women tested for HIV at Chinhoyi Hospital showed that only six had disclosed their HIV status. We investigated the determinants of nondisclosure of HIV status. A cross sectional analytic study was conducted at six health facilities in Makonde district. The Theory of Planned Behaviour was adapted to guide socio-cultural variables assessed. Antenatal and postnatal women tested for HIV in the PMTCT program who consented to participate were interviewed. We enrolled 334 women. Thirty four percent (114) did not disclose their HIV status. Among HIV positive respondents, 43% (25) did not disclose their status. Women who believed disclosure caused physical abuse (OR=1.81, 95% CI: 1.17-2.90), caused divorce (OR=2.01, 95% CI: 1.25-3.22) and was unimportant (OR= 2.26, 95% CI: 1.33-3.87) were two times less likely to disclose their status. Respondents who received group HIV pre-test counselling were 2.4 times more likely not to disclose. Receiving ANC HIV education at least twice and referral for psychosocial support were significantly protective [OR 0.54 (95% CI 0.24-0.63) and 0.16 (95% CI: 0.06-0.41) respectively. Independent determinants of nondisclosure among HIV positive women were perception that disclosure would cause divorce (AOR=7.82, p=0.03), living with an extended family (AOR=10.3, p=0.01) and needing spousal approval of HIV testing (AOR=0.11, pcauses divorce, abuse or is unimportant contributes to nondisclosure. Identifying women with social challenges and strengthening their referral for psychosocial support can improve disclosure of HIV status and reduce mother to child transmission of HIV.

College Women's Responses to a Celebrity Health Disclosure.

Drizin, Julia H; Malcarne, Vanessa L; Schiaffino, Melody K; Wells, Kristen J

2017-08-18

Celebrities can have a powerful influence on people's health-related attitudes and behaviors, often by publicly disclosing their own personal health decisions. In May 2013, Angelina Jolie, an internationally recognized actress, director, and author, wrote an op-ed for the New York Times disclosing her decision to undergo a prophylactic double mastectomy to reduce her risk of breast cancer after learning that she carried the BRCA1 gene mutation. This cross-sectional study examined whether exposure to Angelina Jolie and her mastectomy disclosure and parasocial involvement (PSI) with Angelina Jolie were related to female college students' perceived risk of breast cancer and breast cancer screening intentions. Participants were 198 female undergraduate college students. Data were collected anonymously via an online questionnaire and analyzed using bivariate correlations and hierarchical linear regression analyses. Neither exposure to Angelina and her disclosure nor PSI with Angelina Jolie was related to participants' attitudes or behaviors related to breast cancer. However, having a family history of cancer was associated with more exposure to Angelina Jolie and her disclosure. Findings suggest that exposure to and PSI with a celebrity who has disclosed a health-related message may not be sufficient to motivate young women to change their health-related attitudes and behaviors. Future studies should explore how celebrities disclosing different types of health issues might influence the attitudes and behaviors of young women.

To compare in person versus computerized screening for intimate partner violence (IPV) in a hospital-based prenatal clinic and explore women's assessment of the screening methods. We compared patient IPV disclosures on a computerized questionnaire to audio-taped first obstetric visits with an obstetric care provider and performed semi-structured interviews with patient participants who reported experiencing IPV. Two-hundred and fifty patient participants and 52 provider participants were in the study. Ninety-one (36%) patients disclosed IPV either via computer or in person. Of those who disclosed IPV, 60 (66%) disclosed via both methods, but 31 (34%) disclosed IPV via only one of the two methods. Twenty-three women returned for interviews. They recommended using both types together. While computerized screening was felt to be non-judgmental and more anonymous, in person screening allowed for tailored questioning and more emotional connection with the provider. Computerized screening allowed disclosure without fear of immediate judgment. In person screening allows more flexibility in wording of questions regarding IPV and opportunity for interpersonal rapport. Both computerized or self-completed screening and in person screening is recommended. Providers should address IPV using non-judgmental, descriptive language, include assessments for psychological IPV, and repeat screening in person, even if no patient disclosure occurs via computer.

‘Daddy ran out of tadpoles’: how parents tell their children that they are donor conceived, and what their 7-year-olds understand

Science.gov (United States)

Blake, L.; Casey, P.; Readings, J.; Jadva, V.; Golombok, S.

2010-01-01

BACKGROUND The present study explored the process of disclosure in gamete donation families in the UK. METHODS Interviews were conducted with 23 mothers and 15 fathers who had told their 7-year-old child about the nature of their conception. Twelve children were interviewed about what they understood and how they felt about their donor conception (DC). RESULTS The majority of families had disclosed by the age of four and mothers were found to be the main disclosers. Although some parents expressed concerns about the disclosure, the majority did not experience difficulties. No child responded to disclosure in a negative way. Seven-year-old children showed little understanding of their DC, despite parents starting the process of disclosure before the age of four. CONCLUSIONS In spite of mothers' concerns about disclosing DC to their children, children responded to disclosure in a neutral way and most parents did not find disclosure to be problematic.

Non-Financial Reporting in Croatia: Current Trends Analysis and Future Perspectives

Directory of Open Access Journals (Sweden)

Adriana Galant

2017-03-01

Full Text Available Non-financial reporting forms part of corporate reporting. Among other, it includes disclosure of information regarding corporate social responsibility (CSR/sustainability issues and as such represent the supplement to the information provided by financial statements. Compared to the financial reporting, non-financial reporting is voluntary in majority of countries, including Croatia. Thus, companies decide on their own whether to disclose on this issue or not. Considering its voluntariness, the aim of this paper is to determine the current state of non-financial reporting in Croatia by identifying the financial characteristics of companies disclosing non-financial reports. In data analysis, the logistic regression was used. The research was conducted on a sample of Croatian publicly listed companies. Obtained results indicate that larger, more profitable and efficient companies are more probable to disclose non-financial reports, while indebtedness is not significant for it. In addition, further development of corporate social accounting is required, as well as promotion of non-financial reporting benefits.

"It's my secret": fear of disclosure among sub-Saharan African migrant women living with HIV/AIDS in Belgium.

Directory of Open Access Journals (Sweden)

Agnes Ebotabe Arrey

Full Text Available Patients with HIV not only have to deal with the challenges of living with an incurable disease but also with the dilemma of whether or not to disclose their status to their partners, families and friends. This study explores the extent to which sub-Saharan African (SSA migrant women in Belgium disclose their HIV positive status, reasons for disclosure/non-disclosure and how they deal with HIV disclosure. A qualitative study consisting of interviews with twenty-eight SSA women with HIV/AIDS was conducted. Thematic content analysis was employed to identify themes as they emerged. Our study reveals that these women usually only disclose their status to healthcare professionals because of the treatment and care they need. This selective disclosure is mainly due to the taboo of HIV disease in SSA culture. Stigma, notably self-stigma, greatly impedes HIV disclosure. Techniques to systematically incorporate HIV disclosure into post-test counseling and primary care services are highly recommended.

Armistead, Lisa; Goodrum, Nada; Schulte, Marya; Marelich, William; LeCroix, Rebecca; Murphy, Debra A

2018-02-09

Nondisclosure of maternal HIV status to young children can negatively impact child functioning; however, many mothers do not disclose due to lack of self-efficacy for the disclosure process. This study examines demographic variations in disclosure self-efficacy, regardless of intention to disclose, and assesses the relationship between self-efficacy and child adjustment via the parent-child relationship among a sample of HIV+ mothers and their healthy children (N = 181 pairs). Mothers completed demographic and self-efficacy measures; children completed measures assessing the parent-child relationship and child adjustment (i.e., worry, self-concept, depression). Across demographics, few mothers reported confidence in disclosure. Results from covariance structural modeling showed mothers endorsing higher self-efficacy had children who reported better relationship quality, and, in turn, reported fewer adjustment difficulties; higher levels of disclosure self-efficacy also directly predicted fewer adjustment problems. Findings offer support for interventions aimed at providing mothers with skills to enhance confidence for disclosing their HIV status.

2008-01-01

No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed.

Method for monitoring drilling materials for gamma ray activity

International Nuclear Information System (INIS)

Smith, H.D. Jr.; Arnold, D.M.; Schultz, W.E.

1985-01-01

In the preferred and illustrated embodiment taught herein, method steps for monitoring of raw materials to be used in drilling mud are disclosed. The materials are monitored for radioactivity. Procedures for taking such measurements are disclosed, and the extent of gamma radioactivity in the raw materials used in drilling mud is, determined. This is correlated to the increased radiation attributable to mud made from these materials and the effect the mud would have on gamma ray measuring logs. An alternate procedure for testing drilling mud, typically at the well site, is also disclosed. The method detects mud radioactivity from any additives including barite, potassium chloride, well cuttings or others. Excessive background levels due to mud gamma radioactivity in a well may very well mask the data obtained by various logging procedures dependent on gamma radiation. Procedures are also described for either rejecting mud which is too radioactive or correcting the log measurements for mud effects

Avoiding malpractice suits through the use of informed consent.

Science.gov (United States)

Annas, G J

1976-03-01

The doctrine of informed consent is based on a long tradition of promoting self-autonomy and rational decision-making. The amount of information required to be disclosed by the doctor to the patient is that which permits the patient to decide for himself whether or not to undergo the recommended treatment. It includes information about risks of death or serious bodily harm, probability of success, problems of recuperation, and alternative modes of treatment. Disclosing such information contributes to the doctor-patient relationship and therefore makes recourse to malpractice litigation in the face of an unsatisfactory or untoward result less likely. Attempts to abolish the doctrine are potentially counterproductive and could lead to widespread mistrust of the medical profession on the part of a society that increasingly demands more information in all areas. Physicians will best serve both themselves and their patients by fully disclosing all relevant information before asking patients to consent to specific therapies.

To describe factors related to diagnosis, identity disclosure, and social support among lesbian, gay, bisexual, and transgender (LGBT) patients with cancer, and to explore associations between these factors and self-rated health. Cross-sectional self-report survey design using descriptive and exploratory multivariate statistical approaches. Online, Internet-based. 291 LGBT patients (89% Caucasian; 50% gay, 36% lesbian, 7% bisexual, 3% transgender) with mixed cancers. Participants completed a researcher-designed online survey assessing experiences of cancer diagnosis among LGBT patients at a single time point. Demographics, which provider(s) delivered the patients' cancer diagnoses, to whom patients had disclosed their LGBT identity, how they disclosed, who was on their social support team at the time of diagnosis, and current self-rated health. 79% of participants reported disclosing their identities to more than one cancer care provider. Participants most commonly introduced the topic of LGBT identity themselves, sometimes as a way to correct heterosexual assumptions (34%). Friends were the most common members of LGBT patients' support teams (79%). Four disclosure and support factors were consistently associated with better self-rated health. Disclosure of LGBT identity is a common experience in the context of cancer care, and disclosure and support factors are associated with better self-reported health among LGBT patients. Creating safe environments for LGBT patients to disclose could improve cancer care delivery to this underserved population. Nurses and other providers should acknowledge and include diverse support team members in LGBT patients' care.

Formal plan for self-disclosure enhances supported employment outcomes among young people with severe mental illness.

Science.gov (United States)

McGahey, Ellie; Waghorn, Geoffrey; Lloyd, Chris; Morrissey, Shirley; Williams, Philip Lee

2016-04-01

Young people with mental illness experience high levels of unemployment, which can be related to stigma and discrimination. This may result from poor choices in disclosing personal information, such as their mental illness diagnosis, in the workplace. The aim of this study was to investigate the predictive validity of a formal plan to manage personal information (PMPI) during the early stages of supported employment. The focal question was: does the use of a brief structured PMPI lead to more employment outcomes for young people with a mental illness? A sample of 40 young unemployed mental health service users (mean age 23.9 years), who were also attending employment services on the Gold Coast, was asked about their disclosure preferences. If they preferred not to disclose at all, they did not complete a plan for managing personal information. If they preferred to disclose some personal information, they were provided with assistance to complete a PMPI. Baseline information was gathered from two equal groups of 20 individuals. Employment status was ascertained at a 6-week follow-up interview. Those who completed a plan to manage their personal information had 4.9 times greater odds of employment at 6 weeks than those who preferred not to disclose any personal information. A formal PMPI has promising predictive validity with respect to job seekers not opposed to pragmatic forms of self-disclosure. Further research is needed to examine other properties of this decision-making tool. © 2014 Wiley Publishing Asia Pty Ltd.

Full Text Available The Department of Cultural Heritage of the University of Padova investigated the topic of film-induced tourism in a year-long project, concluded in April 2015, titled Strumenti innovativi per la promozione turistica: film-induced tourism (Novel Tools to Promote Tourism: Film-induced Tourism. The project was financed by the Veneto Region through ESF funds. It brought together the expertise of film scholars, computer scientists and destination management experts, in partnership with public bodies (Provincia di Padova and ICT companies. The goal of the project was to develop an information system that fosters film-induced tourism combining data about a geographical area and the movies produced in it. The system is designed as a platform to store and convey rich contents, able to address the needs of the tourist but also of stakeholders as DMOs and film commissions. The system was planned as a model for the destinations which could take advantage of a significant cinematographic background, yet are unlikely to spontaneously produce considerable film-induced tourism phenomena. The province of Padova has been used as a case study.   Il Dipartimento dei Beni Culturali dell’Università di Padova ha da poco concluso un progetto di ricerca intitolato Strumenti innovativi per la promozione turistica: film-induced tourism, finanziato dalla Regione Veneto con fondi europei FSE, che ha visto coinvolti studiosi di cinema, di informatica ed esperti di destination management, in partenariato con enti pubblici (Provincia di Padova e aziende private del ramo ICT. L’obiettivo del progetto è stato lo sviluppo di un sistema informatico che combini i dati relativi ad un territorio e i film ivi realizzati, con lo scopo di promuovere il film-induced tourism. Il sistema è disegnato come una piattaforma in grado di memorizzare, elaborare e rendere fruibili contenuti multimediali e di ricco carattere informativo, capaci di intercettare sia le necessità del turista che quelle di stakeholders quali DMO e film commission. Il sistema si propone come modello per le realtà che godono di una tradizione cinematografica ricca ma non sufficiente a far nascere fenomeni spontanei di “cineturismo”.

Environmental and social responsibility reporting. Do Macedonian companies disclose those information and how?

Directory of Open Access Journals (Sweden)

Mrsik Jadranka

2015-12-01

Full Text Available Incorporating environmental impact into financial reports is becoming standard practice in the 21st Century. Investors are aware of the need for environmentally correct operations since failures in this domain lower the price of shares. However, in terms of regulation, in most of the countries, environmental reporting remains voluntary. Institutions dealing with development and promotion of the modern accounting and financial reporting standards encourage companies to concurrently report for their environmental activities. The only question is how. Accounting may include information on the environmental impact only if it is quantitative and monetary. Since many nuances of the issues remain difficult to quantify, corporations opt to separately report on their environmental practices. The aim of this paper is to examine the accounting and stock market regulations and the practice of reporting for environmental impact of the operations of the leading Macedonian companies. We selected ten companies that make the Macedonian Stock Exchange Index and additional five companies with significant environmental impact. We reviewed their annual reports and interviewed their financial officers. The results show that the environmental and social responsibility reporting is left to the companies and their management and its perception of the need for keeping posted the major stakeholders and the most appropriate way to do it. As a consequence, many large Macedonian companies do not refer to these issues in their annual addressing to the stakeholders. The findings of this paper can motivate the regulatory body and the government to require more transparency and disclosure of the sustainability information.

(Re)disclosing physician financial interests: rebuilding trust or making unreasonable burdens on physicians?

Science.gov (United States)

Sperling, Daniel

2017-06-01

Recent professional guidelines published by the General Medical Council instruct physicians in the UK to be honest and open in any financial agreements they have with their patients and third parties. These guidelines are in addition to a European policy addressing disclosure of physician financial interests in the industry. Similarly, In the US, a national open payments program as well as Federal regulations under the Affordable Care Act re-address the issue of disclosure of physician financial interests in America. These new professional and legal changes make us rethink the fiduciary duties of providers working under new organizational and financial schemes, specifically their clinical fidelity and their moral and professional obligations to act in the best interests of patients. The article describes the legal changes providing the background for such proposals and offers a prima facie ethical analysis of these evolving issues. It is argued that although disclosure of conflicting interest may increase trust it may not necessarily be beneficial to patients nor accord with their expectations and needs. Due to the extra burden associated with disclosure as well as its implications on the medical profession and the therapeutic relationship, it should be held that transparency of physician financial interest should not result in mandatory disclosure of such interest by physicians. It could lead, as some initiatives in Europe and the US already demonstrate, to voluntary or mandatory disclosure schemes carried out by the industry itself. Such schemes should be in addition to medical education and the address of the more general phenomenon of physician conflict of interest in ethical codes and ethical training of the parties involved.

The clinical spectrum is wide and usually characterized by chronic fatigue, cramps, muscle weakness and paresthesiae. We describe a case of a 43 year-old male patient with early onset of knee arthritis and no other symptoms. Ultrasound revealed diffuse and confluent hyperechoic deposits in cartilage, fibrocartilage of the menisci and synovium and calcium pyrophosphate crystals were observed in the synovial fluid of the knee. The concomitant presence of hypomagnesemia, hypocalciuria and hypokalemia made clear the diagnosis of Gitelman’s syndrome associated with chondrocalcinosis.

Expert readers have been repeatedly reported to misperceive the centre of visual stimuli, shifting systematically to the left the bisection of any lines (pseudoneglect) while showing a cross-over effect while bisecting different types of orthographic strings (Arduino et al., 2010, Neuropsychologia, 48, 2140). This difference has been attributed to asymmetrical allocation of attention that visuo-verbal material receives when lexical access occurs (e.g., Fischer, 2004, Cognitive Brain Research, 4, 163). The aim of this study was to further examine which visual features guide recognition of potentially orthographic materials. To disentangle the role of orthography, heterogeneity, and visuo-perceptual discreteness, we presented Italian unimpaired adults with four experiments exploiting the bisection paradigm. The results showed that a cross-over effect emerges in most discrete strings, especially when their internal structure, that is being composed of heterogeneous elements, is suggestive of orthographically relevant material. Interestingly, the cross-over effect systematically characterized the processing of letter strings (Experiment 2) and words (Experiments 3 and 4), whether visually discrete or not. Overall, this pattern of results suggests that neither discreteness nor heterogeneity per se are responsible for activating visual scanning mechanisms implied in text exploration, although both contribute to increasing the chance of a visual stimulus undergoing a perceptual analysis dedicated to pre-lexical processing. © 2018 The British Psychological Society.

MRI is used routinely in research with children to generate new knowledge about brain development. The detection of unexpected brain abnormalities (incidental findings; IFs) in these studies presents unique challenges. While key issues surrounding incidence and significance, duty of care, and burden of disclosure have been addressed substantially for adults, less empirical data and normative analyses exist for minors who participate in minimal risk research. To identify ethical concerns and fill existing gaps, we conducted a comprehensive review of papers that focused explicitly on the discovery of IFs in minors. The discourse in the 21 papers retrieved for this analysis amply covered practical issues such as informed consent and screening, difficulties in ascertaining clinical significance, the economic costs and burden of responsibility on researchers, and risks (physical or psychological). However, we found little discussion about the involvement of minors in decisions about disclosure of IFs in the brain, especially for IFs of low clinical significance. In response, we propose a framework for managing IFs that integrates practical considerations with explicit appreciation of rights along the continuum of maturity. This capacity-adjusted framework emphasizes the importance of involving competent minors and respecting their right to make decisions about disclosure. Copyright © 2013 Wiley Periodicals, Inc.

Micro-scale novel stable isotope fractionation during weathering disclosed by femtosecond laser ablation

The stable isotope fractionation of metals and metalloids during chemical weathering and alteration of rocks at low temperature is a topic receiving increasing scientific attention. For these systems, weathering of primary minerals leads to selective partitioning of isotopes between the secondary minerals formed from them, and the dissolved phase of soil or river water. While the isotopic signatures of these processes have been mapped-out at the catchment or the soil scale, the actual isotopic fractionation is occurring at the mineral scale. To identify the processes underlying such micro-scale fractionation, the development of micro-analytical tools allows to investigate mechanisms of isotope fractionation in-situ, in combination with textural information of weathering reactions. We have developed a second-generation UV femtosecond (fs) laser system at GFZ Potsdam. The advantage of UV-fs laser ablation is the reduction of laser-induced isotopic and elemental fractionation by avoiding 'thermal effects' during ablation, such that accurate isotope ratios can be measured by standard-sample-standard bracketing using laser ablation multicollector ICP-MS; where the matrix of the bracketing standard does not need to match that of the sample [1]. Our system consists of the latest generation femtosecond solid-state laser (Newport Spectra Physics Solstice), producing an ultra short pulse width of about 100 femtoseconds at a wavelength of 196 nm. The system is combined with a custom-build computer-controlled sample stage and allows fully automated isotope analyses through synchronised operation of the laser with the Neptune MC-ICP-MS. To assess precision and accuracy of our laser ablation method, we analysed various geological reference materials. We obtained δ30Si values of -0.31 ± 0.23 (2SD, n = 13) for basalt glass BHVO-2G, and -1.25 ± 0.21 (2SD, n = 27) for pure Si IRMM17 when bracketed against NBS-28 quartz. δ56Fe and δ26Mg values obtained from non-matrix matched standard-sample-bracketing laser ablation analyses on sulfides, oxides and silicates agree within 0.15 permil to measurements done by solution MC-ICP-MS after chromatographic matrix separation. With our laser ablation method all compartments of the weathering zone can be analysed with minimal sample preparation [2]. In a first application, we investigate Si isotope fractionation during deep (10 m) core stone weathering, where crystalline rock is altered, producing secondary clay minerals along 20 micrometer wide (biogenic?) alteration textures. While unweathered centers of plagioclase grains show a homogenous Si isotope composition of δ30Si = -0.20 ± 0.17 permil (2SD, n=12), the secondary weathering products found in fissures within and between plagioclase grains consistently show negative δ30Si values - as low as -1.13 permil. Comparison with isotope studies at the soil and catchment scale suggests that the isotopic weathering signatures found in dissolved and particulate Si in rivers can be traced to processes operating at the micro scale.
