Role of cholinesterase inhibitors in Parkinson's disease and dementia with Lewy bodies

This article reviews the cholinergic changes in Parkinson's disease and dementia (PDD) and dementia with Lewy bodies (DLB), their potential clinical implications, and the available evidence for cholinesterase inhibitors in the treatment of PDD and DLB. Marked neuronal loss of cholinergic nuclei, reduced cholinergic markers in the neocortex, hippocampus, and selected thalamic nuclei, and receptor changes have been reported. One large and 2 small placebo-controlled trials and nearly 20 open-label studies suggest that cholinesterase inhibitors have a positive effect on cognition, psychiatric symptoms, and global function in patients with DLB and PDD. The treatment is well tolerated in most patients without any apparent worsening of extrapyramidal motor features. Given the high risk of severe sensitivity reactions and increased risk of cerebrovascular incidents during treatment with neuroleptics, more clinical trials of cholinesterase inhibitors are encouraged to establish their precise role in DLB and PDD.

Critical incidence reporting systems - an option in equine anaesthesia? Results from a panel meeting.

OBJECTIVE To provide a brief introduction into Critical Incident Reporting Systems (CIRS) as used in human medicine, and to report the discussion from a recent panel meeting discussion with 23 equine anaesthetists in preparation for a new CEPEF-4 (Confidential Enquiry into Perioperative Equine Fatalities) study. STUDY DESIGN Moderated group discussions, and review of literature. METHODS The first group discussion focused on the definition of 'preventable critical incidents' and/or 'near misses' in the context of equine anaesthesia. The second group discussion focused on categorizing critical incidents according to an established framework for analysing risk and safety in clinical medicine. RESULTS While critical incidents do occur in equine anaesthesia, no critical incident reporting system including systematic collection and analysis of critical incidents is in place. CONCLUSIONS AND CLINICAL RELEVANCE Critical incident reporting systems could be used to improve safety in equine anaesthesia - in addition to other study types such as mortality studies.

Envy on Facebook: a hidden threat to users’ life satisfaction?

The wealth of social information presented on Facebook is astound-ing. While these affordances allow users to keep up-to-date, they also produce a basis for social comparison and envy on an unprecedented scale. Even though envy may endanger users’ life satisfaction and lead to platform avoidance, no study exists uncovering this dynamics. To close this gap, we build on responses of 584 Facebook users collected as part of two independent studies. In study 1, we explore the scale, scope, and nature of envy incidents triggered by Face-book. In study 2, the role of envy feelings is examined as a mediator between intensity of passive following on Facebook and users’ life satisfaction. Con-firming full mediation, we demonstrate that passive following exacerbates envy feelings, which decrease life satisfaction. From a provider’s perspective, our findings signal that users frequently perceive Facebook as a stressful environ-ment, which may, in the long-run, endanger platform sustainability.

Sex Trafficking of Minors in the U.S.: Implications for Policy, Prevention and Research

Context: Information currently available on the trafficking of minors in the U.S. for commercial sexual exploitation includes approximations of the numbers involved, risk factors that increase the likelihood of victimization and methods of recruitment and control. However, specific characteristics about this vulnerable population remain largely unknown. Objective: This article has two distinct purposes. The first is to provide the reader with an overview of available information on minor sex trafficking in the U.S. The second is to present findings and discuss policy, research, and educational implications from secondary data analysis of 115 cases of minor sex trafficking in the U.S. Design: Minor sex trafficking cases were identified through two main venues - a review of U.S. Department of Justice press releases of human trafficking cases and an online search of media reports. Searches covered the time period from October 28, 2000, which coincided with the passage of the VTVPA through October 31, 2009. Cases were included in analysis if the incident involved at least one victim under the age of 18, occurred in the U.S., and at least one perpetrator had been arrested, indicted, or convicted. Results: A total of 115 separate incidents involving at least 153 victims were located. These occurrences involved 215 perpetrators, with the majority of them having been convicted (n = 117, 53.4%), The number of victims involved in a single incident ranged from 1 to 9. Over 90% of victims were female who ranged in age from 5 to 17 years. There were more U.S. minor victims than those from other countries. Victims had been in captivity from less than 6 months to 5 years. Minors most commonly fell into exploitation through some type of false promise indicated (16.3%, n = 25), followed by kidnapping (9.8%, n = 15). Over a fifth of the sample (22.2%, n = 34) were abused through two commercial sex practices, with almost all (94.1%, n = 144) used in prostitution. One of every five victims (24.8%, n = 38) had been advertised on an Internet website. Conclusions: Results of a review of known information about minor sex trafficking and findings from analysis of 115 incidents of the sex trafficking of youth in the U.S. indicate a need for stronger legislation to educate various professional groups, more comprehensive services for victims, stricter laws for pimps and traffickers, and preventive educational interventions beginning at a young age.

Analysis of sport psychology consultancy at three Olympic Games: Facts and figures

Objectives Despite many reports on best practises regarding onsite psychological services, little research has attempted to systematically explore the frequency, issues, nature and client groups of onsite sport psychology consultancy at the Olympic Games. The present paper will fill this gap through a systematic analysis of the sport psychology consultancy of the Swiss team for the Olympic Games of 2006 in Turin, 2008 in Beijing and 2010 in Vancouver. Design Descriptive research design. Methods The day reports of the official sport psychologist were analysed. Intervention issues were labelled using categories derived from previous research and divided into the following four intervention-issue dimensions: “general performance”, “specific Olympic performance”, “organisational” and “personal” issues. Data were analysed using descriptive statistics, chi square statistics and odds ratios. Results Across the Olympic Games, between 11% and 25% of the Swiss delegation used the sport psychology services. On average, the sport psychologist provided between 2.1 and 4.6 interventions per day. Around 50% of the interventions were informal interventions. Around 30% of the clients were coaches. The most commonly addressed issues were performance related. An association was observed between previous collaboration, intervention likelihood and intervention theme. Conclusions Sport psychologists working at the Olympic Games are fully engaged with daily interventions and should have developed ideally long-term relationships with clients to truly help athletes with general performance issues. Critical incidents, working with coaches, brief contact interventions and team conflicts are specific features of the onsite consultancy. Practitioners should be trained to deal with these sorts of challenges.

In the aftermath of medical error : Caring for patients, family, and the healthcare workers involved

Medical errors, in particular those resulting in harm, pose a serious situation for patients ("first victims") and the healthcare workers involved ("second victims") and can have long-lasting and distressing consequences. To prevent a second traumatization, appropriate and empathic interaction with all persons involved is essential besides error analysis. Patients share a nearly universal, broad preference for a complete disclosure of incidents, regardless of age, gender, or education. This includes the personal, timely and unambiguous disclosure of the adverse event, information relating to the event, its causes and consequences, and an apology and sincere expression of regret. While the majority of healthcare professionals generally support and honest and open disclosure of adverse events, they also face various barriers which impede the disclosure (e.g., fear of legal consequences). Despite its essential importance, disclosure of adverse events in practice occurs in ways that are rarely acceptable to patients and their families. The staff involved often experiences acute distress and an intense emotional response to the event, which may become chronic and increase the risk of depression, burnout and post-traumatic stress disorders. Communication with peers is vital for people to be able to cope constructively and protectively with harmful errors. Survey studies among healthcare workers show, however, that they often do not receive sufficient individual and institutional support. Healthcare organizations should prepare for medical errors and harmful events and implement a communication plan and a support system that covers the requirements and different needs of patients and the staff involved.

Minority Rights and Humanitarianism: The international campaign for the Ukrainians in Poland, 1930-31

In October 1930, violent action of the Polish security forces against the Ukrainian population in Eastern Galicia resulted in an international campaign for the Ukrainians in Poland. Its central claim was the condemnation of these incidents as a violation of the Minorities Treaty of the League of Nations. The article focuses on the involved British extra-parliamentary groups and their international federations as well as leftist intellectuals, socialist parties and the Labour and Socialist International. In most cases, the commitment of the activists was motivated by the desire to expose a humanitarian scandal while the implementation of minority rights played a minor role. When it turned out that the first reports had presented an exaggerated version of the events, they shifted their focus to the Polish opposition whose persecution started in November 1930.

Assessing distractors and teamwork during surgery: developing an event-based method for direct observation

OBJECTIVE: To develop a behavioural observation method to simultaneously assess distractors and communication/teamwork during surgical procedures through direct, on-site observations; to establish the reliability of the method for long (>3 h) procedures. METHODS: Observational categories for an event-based coding system were developed based on expert interviews, observations and a literature review. Using Cohen's κ and the intraclass correlation coefficient, interobserver agreement was assessed for 29 procedures. Agreement was calculated for the entire surgery, and for the 1st hour. In addition, interobserver agreement was assessed between two tired observers and between a tired and a non-tired observer after 3 h of surgery. RESULTS: The observational system has five codes for distractors (door openings, noise distractors, technical distractors, side conversations and interruptions), eight codes for communication/teamwork (case-relevant communication, teaching, leadership, problem solving, case-irrelevant communication, laughter, tension and communication with external visitors) and five contextual codes (incision, last stitch, personnel changes in the sterile team, location changes around the table and incidents). Based on 5-min intervals, Cohen's κ was good to excellent for distractors (0.74-0.98) and for communication/teamwork (0.70-1). Based on frequency counts, intraclass correlation coefficient was excellent for distractors (0.86-0.99) and good to excellent for communication/teamwork (0.45-0.99). After 3 h of surgery, Cohen's κ was 0.78-0.93 for distractors, and 0.79-1 for communication/teamwork. DISCUSSION: The observational method developed allows a single observer to simultaneously assess distractors and communication/teamwork. Even for long procedures, high interobserver agreement can be achieved. Data collected with this method allow for investigating separate or combined effects of distractions and communication/teamwork on surgical performance and patient outcomes.

Time for a break: admissions to an urban emergency department after working out-a retrospective study from Switzerland.

Background. The present retrospective study was intended to investigate whether working out and other low-speed sports can provoke cardiovascular, neurological, or traumatic damage. Material and Methods. Patient data from 2007 to 2013 was collected and saved at the university department of emergency medicine in an electronic patient record database. Results. Of the 138 patients included in this study, 83.3% (n = 115) were male and 16.7% female (n = 23). Most admissions were due to musculoskeletal accidents (n = 77; 55.8%), followed by neurological incidents (n = 23; 16.7%), cardiovascular incidents (n = 19; 13.8%), soft tissue injuries (n = 3; 2.2%), and others (n = 16; 11.6%). The mean age of the allover injured people was 36.7 years. The majority of the patients (n = 113; 81.9%) were treated as outpatients; 24 (17.4%) were inpatients. Discussion. In Switzerland, this is the first study that describes emergency department admissions after workout and examines trauma and neurological and cardiovascular incidents. As specific injuries, such as brain haemorrhages, STEMIs, and epileptic seizures, were relatively frequent, it was hypothesised that workout with its physiological changes may be an actual trigger for these injuries, at least for a specific population. Conclusion. Strenuous physical activity may trigger the risk of cardiovascular, neurological, or trauma events.

Long-term follow-up of maxillary fixed retention: survival rate and periodontal health.

AIM To assess the long-term success of maxillary fixed retainers, investigate their effect on gingival health, and analyse the survival rate after a mean period of 7 years (minimum 5 years) in retention. SUBJECTS AND METHODS Forty one subjects were included in the study A clinical examination of the upper canine to canine region including gingival index (GI), plaque index, probing depth, and bleeding on probing (BOP) was performed. Intraoral photographs and dental impressions were taken and irregularity index was determined and compared to the values of the immediate post-therapeutic values; failures of retainers were also recorded and analysed. RESULTS The mean observed retention time was 7 years and 5 months. Irregularity index: Changes occurring during retention were statistically different between the lateral incisors bonded to retainers and the canines not bonded to retainers. Only six patients showed changes in irregularity index of the lateral incisors in spite of a retainer in place. Periodontal health: The median value of the GI for all teeth bonded to upper retainers was 1.10 and the median value of the plaque index (PI) was 1.14. PI was not a significant predictor of GI. The overall BOP of the bonded teeth to the retainer for each participant was 22.3 per cent. Failure rate: Twenty-eight out of 41 patients experienced no failure of the upper bonded retainer (68.3 per cent). Detachments were the most frequent incidents. CONCLUSION Although plaque accumulation might be increased in patients with already poor oral hygiene, maxillary bonded retainers caused no significant negative effects on the periodontal health.

Ethnic disparity in defensive coping endothelial responses: The SABPA study

OBJECTIVES Defensive coping (DefS) in Blacks has been associated with greater cardiovascular risk than in their White counterparts. We examined associations between endothelial function mental stress responses and markers of vascular structure in a bi-ethnic cohort. METHODS We examined vascular function and structure in 368 Black (43.84±8.31years) and White Africans (44.78±10.90years). Fasting blood samples, 24h blood pressure, left carotid intima-media thickness of the far wall (L-CIMTf), and left carotid cross-sectional wall area (L-CSWA) values were obtained. von Willebrand factor (VWF), endothelin-1 (ET-1) and nitric oxide metabolite (NOx) responses to the Stroop mental stress test were calculated to assess endothelial function. DefS was assessed using the Coping Strategy Indicator questionnaire. Interaction between main effects was demonstrated for 283 participants with DefS scores above the mean of 26 for L-CIMTf. RESULTS Blunted stress responses for VWF (men 16.71% vs. 51.10%; women 0.85% vs. 42.09%, respectively) and NOx (men -64.52% vs. 74.89%; women -76.16% vs. 113.29%, respectively) were evident in the DefS Blacks compared to the DefS Whites (p<0.001). ET-1 increased more in Blacks (men 150% and women 227%, p<0.001) compared to the Whites (men 61.25% and women 35.49%, p<0.001). Ambulatory pulse pressure, but not endothelial function markers, contributed to L-CIMTf (ΔR(2)=0.11 p<0.001), and L-CSWA (ΔR(2)=0.08, p<0.001) in DefS African men but not in any other group. CONCLUSIONS Blunted stress-induced NOx and VWF responses and augmented ET-1 responses in DefS Blacks indicate endothelial dysfunction. DefS may facilitate disturbed endothelial responses and enforce vascular remodelling via compensatory increases in pulse pressure in Black men. These observations may indicate an increased risk of cardiovascular incidents via functional and structural changes of the vasculature in DefS Blacks.

Acute mental stress and hemostasis: When physiology becomes vascular harm

Stress-induced activation of the sympathoadrenal medullary system activates both the coagulation and fibrinolysis system resulting in net hypercoagulability. The evolutionary interpretation of this physiology is that stress-hypercoagulability protects a healthy organism from excess bleeding should injury occur in fight-or-flight situations. In turn, acute mental stress, negative emotions and psychological trauma also are triggering factors of atherothrombotic events and possibly of venous thromboembolism. Individuals with pre-existent atherosclerosis and impaired endothelial anticoagulant function are the most vulnerable to experience onset of acute coronary events within two hours of intense emotions. A range of sociodemographic and psychosocial factors (e.g., chronic stress and negative affect) might critically intensify and prolong stress-induced hypercoagulability. In contrast, several pharmacological compounds, dietary flavanoids, and positive affect mitigate the acute prothrombotic stress response. Studies are needed to investigate whether attenuation of stress-hypercoagulability through medications and biobehavioral interventions reduce the risk of thrombotic incidents in at-risk populations.

Power Games in Strategy Formation Processes – A Performative Interpretation

The article approaches an understanding of power within strategy formation processes established by verbal and bodily communication. On this note, we examined concepts of power constituted by hierarchy and developed a conceptual framework for a performative interpretation of power. In line with Austin’s (1962) and Butler’s (1990, 1993, 1997) concept of performativity as well as strategy-as-practice research (Balogun et al., 2007; Jarzabkowski & Spee, 2009) we ask: How is persuasion achieved by strategic actors during strategy formation processes? To explore verbal and bodily communication empirically we developed an experimental setting in a small high-tech company located in Germany in December, 2012. The Results indicate that (1) during critical incidents – when perspectives clash – actors use arguments to gain persuasion. (2) The data illustrates that independently of their hierarchical position within the company, strategic actors show an equal distribution of argumentative techniques.

Gender Difference in Emotional and Behavioral Responses of Being Rendered Invisible

This study examined gender differences in emotional and behavioral responses to an experience of being invisible to others. Invisibility was defined as being ignored, slighted and overlooked by others. Participants recalled their own experience and answered questions about it and their responses on an anonymous web-based survey. Although such experiences could be very unpleasant, people may respond to such negative experiences very differently. It was hypothesized that in a patriarchal society like the United States in which men hold more power than women, that men would show emotion that was more aggressive such as anger, and respond more violently to incidents they were not respected. Women, on the other hand, were expected to be more subservient in their behavior and responses, show submissive emotions such as sadness, and respond less violently when they were not respected.
