Study Protocol. ECSSIT – Elective Caesarean Section Syntocinon® Infusion Trial. A multi-centre randomised controlled trial of oxytocin (Syntocinon®) 5 IU bolus and placebo infusion versus oxytocin 5 IU bolus and 40 IU infusion for the control of blood loss at elective caesarean section

<p>Abstract</p> <p>Background</p> <p>Caesarean section is one of the most commonly performed major operations in women throughout the world. Rates are escalating, with studies from the United States of America, the United Kingdom, China and the Republic of Ireland reporting rates between 20% and 25%. Operative morbidity includes haemorrhage, anaemia, blood transfusion and in severe cases, maternal death.</p> <p>The value of routine oxytocics in the third stage of vaginal birth has been well established and it has been assumed that these benefits apply to caesarean delivery as well. A slow bolus dose of oxytocin is recommended following delivery of the baby at caesarean section. Some clinicians use an additional infusion of oxytocin for a further period following the procedure. Intravenous oxytocin has a very short half-life (4–10 minutes) therefore the potential advantage of an oxytocin infusion is that it maintains uterine contractility throughout the surgical procedure and immediate postpartum period, when most primary haemorrhages occur. The few trials to date addressing the optimal approach to preventing haemorrhage at caesarean section have been under-powered to evaluate clinically important outcomes. There has been no trial to date comparing the use of an intravenous slow bolus of oxytocin versus an oxytocin bolus and infusion.</p> <p>Methods and design</p> <p>A multi-centre randomised controlled trial is proposed. The study will take place in five large maternity units in Ireland with collaboration between academics and clinicians in the disciplines of obstetrics and anaesthetics. It will involve 2000 women undergoing elective caesarean section after 36 weeks gestation. The main outcome measure will be major haemorrhage (blood loss >1000 ml). A study involving 2000 women will have 80% power to detect a 36% relative change in the risk of major haemorrhage with two-sided 5% alpha.</p> <p>Discussion</p> <p>It is both important and timely that we evaluate the optimal approach to the management of the third stage at elective caesarean section. Safe operative delivery is now a priority and a reality for many pregnant women. Obstetricians, obstetric anaesthetists, midwives and pregnant women need high quality evidence on which to base management approaches. The overall aim is to reduce maternal haemorrhagic morbidity and its attendant risks at elective caesarean section.</p> <p>Trial registration</p> <p>number: ISRCTN17813715</p

Lead exposure in adult males in urban Transvaal Province, South Africa during the apartheid era

Human exposure to lead is a substantial public health hazard worldwide and is particularly problematic in the Republic of South Africa given the country’s late cessation of leaded petrol. Lead exposure is associated with a number of serious health issues and diseases including developmental and cognitive deficiency, hypertension and heart disease. Understanding the distribution of lifetime lead burden within a given population is critical for reducing exposure rates. Femoral bone from 101 deceased adult males living in urban Transvaal Province (now Gauteng Province), South Africa between 1960 and 1998 were analyzed for lead concentration by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Of the 72 black and 29 white individuals sampled, chronic lead exposure was apparent in nearly all individuals. White males showed significantly higher median bone lead concentration (ME = 10.04 µg·g−1), than black males (ME = 3.80 µg·g−1) despite higher socioeconomic status. Bone lead concentration covaries significantly, though weakly, with individual age. There was no significant temporal trend in bone lead concentration. These results indicate that long-term low to moderate lead exposure is the historical norm among South African males. Unexpectedly, this research indicates that white males in the sample population were more highly exposed to lead

The Effect of Performance-Based Financial Incentives on Improving Patient Care Experiences: A Statewide Evaluation

Patient experience measures are central to many pay-for-performance (P4P) programs nationally, but the effect of performance-based financial incentives on improving patient care experiences has not been assessed. The study uses Clinician &amp; Group CAHPS data from commercially insured adult patients (n = 124,021) who had visits with 1,444 primary care physicians from 25 California medical groups between 2003 and 2006. Medical directors were interviewed to assess the magnitude and nature of financial incentives directed at individual physicians and the patient experience improvement activities adopted by groups. Multilevel regression models were used to assess the relationship between performance change on patient care experience measures and medical group characteristics, financial incentives, and performance improvement activities. Over the course of the study period, physicians improved performance on the physician-patient communication (0.62 point annual increase, p &lt; 0.001), care coordination (0.48 point annual increase, p &lt; 0.001), and office staff interaction (0.22 point annual increase, p = 0.02) measures. Physicians with lower baseline performance on patient experience measures experienced larger improvements (p &lt; 0.001). Greater emphasis on clinical quality and patient experience criteria in individual physician incentive formulas was associated with larger improvements on the care coordination (p &lt; 0.01) and office staff interaction (p &lt; 0.01) measures. By contrast, greater emphasis on productivity and efficiency criteria was associated with declines in performance on the physician communication (p &lt; 0.01) and office staff interaction (p &lt; 0.001) composites. In the context of statewide measurement, reporting, and performance-based financial incentives, patient care experiences significantly improved. In order to promote patient-centered care in pay for performance and public reporting programs, the mechanisms by which program features influence performance improvement should be clarified

Use, acceptability and impact of booklets designed to support mental health self-management and help seeking in schools:Results of a large randomised controlled trial in England

Mental health booklets may provide a low-cost means of promoting mental health self-management and help seeking in schools. The aim of the study was to assess the (a) use, (b) acceptability and (c) impact of booklets for students in primary (10-11 years) and secondary school (12-13 years) alone and in conjunction with funding for targeted mental health support. This was a 2 × 2 factorial cluster randomized controlled trial, in which 846 schools in England were randomly allocated to receive/not receive: (1) booklets for students containing information on mental health self-management and help seeking, and (2) funding for mental health support as part of a national mental health initiative. 14,690 students (8139 primary, 6551 secondary) provided self-report on mental health, quality of life (baseline and 1 year follow-up) and help seeking (follow-up). (a) Approximately, 40 % primary school students and 20 % secondary school students reported seeing the booklets. (b) Of these, 87 % of primary school students reported that the booklet was 'very helpful' or 'quite helpful', compared with 73 % in secondary school. (c) There was no detectable impact of booklets on mental health, quality of life or help seeking, either alone or in conjunction with additional funding through the national mental health initiative. Lack of discernable impact of booklets underscores the need for caution in adopting such an approach. However, it is feasible that the impact was obscured by low uptake or that booklets may be more effective when used in a targeted way

2019 international consensus on cardiopulmonary resuscitation and emergency cardiovascular care science with treatment recommendations : summary from the basic life support; advanced life support; pediatric life support; neonatal life support; education, implementation, and teams; and first aid task forces

The International Liaison Committee on Resuscitation has initiated a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation science. This is the third annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. It addresses the most recent published resuscitation evidence reviewed by International Liaison Committee on Resuscitation Task Force science experts. This summary addresses the role of cardiac arrest centers and dispatcher-assisted cardiopulmonary resuscitation, the role of extracorporeal cardiopulmonary resuscitation in adults and children, vasopressors in adults, advanced airway interventions in adults and children, targeted temperature management in children after cardiac arrest, initial oxygen concentration during resuscitation of newborns, and interventions for presyncope by first aid providers. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the certainty of the evidence on the basis of the Grading of Recommendations, Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence to Decision Framework Highlights sections. The task forces also listed priority knowledge gaps for further research

Exploring medical student learning in the large group teaching environment: examining current practice to inform curricular development

Background Lectures continue to be an efficient and standardised way to deliver information to large groups of students. It has been well documented that students prefer interactive lectures, based on active learning principles, to didactic teaching in the large group setting. Despite this, it is often the case than many students do not engage with active learning tasks and attempts at interaction. By exploring student experiences, expectations and how they use lectures in their learning we will provide recommendations for faculty to support student learning both in the lecture theatre and during personal study time. Methods This research employed a hermeneutic phenomenological approach. Three focus groups, consisting of 19 students in total, were used to explore the experiences of second year medical students in large group teaching sessions. Using generic thematic data analysis, these accounts have been developed into a meaningful account of experience. Results This study found there to be a well-established learning culture amongst students and with it, expectations as to the format of teaching sessions. Furthermore, there were set perceptions about the student role within the learning environment which had many implications, including the way that innovative teaching methods were received. Student learning was perceived to take place outside the lecture theatre, with a large emphasis placed on creating resources that can be taken away to use in personal study time. Conclusions Presented here is a constructive review of reasons for student participation, interaction and engagement in large group teaching sessions. Based on this are recommendations constructed with the view to aid educators in engaging students within this setting. Short term, educators can implement strategies that monopolise on the established learning culture of students to encourage engagement with active learning strategies. Long term, it would be beneficial for educators to consider ways to shift the current student learning culture to one that embraces an active learning curriculum

Effectiveness of psychotherapeutic, pharmacological, and combined treatments for chronic depression: a systematic review (METACHRON)

<p>Abstract</p> <p>Background</p> <p>Chronic depressions represent a substantial part of depressive disorders and are associated with severe consequences. Several studies were performed addressing the effectiveness of psychotherapeutic, pharmacological, and combined treatments for chronic depressions. Yet, a systematic review comparing the effectiveness of multiple treatment options and considering all subtypes of chronic depressions is still missing.</p> <p>Methods/Design</p> <p>Aim of this project is to summarize empirical evidence on efficacy and effectiveness of treatments for chronic depression by means of a systematic review. The primary objectives of the study are to examine, which interventions are effective; to examine, if any differences in effectiveness between active treatment options exist; and to find possible treatment effect modifiers. Psychotherapeutic, pharmacological, and combined treatments will be considered as experimental interventions and no treatment, wait-list, psychological/pharmacological placebo, treatment as usual, and other active treatments will be seen as comparators. The population of patients will include adults with chronic major depression, dysthymia, double depression, or recurrent depression without complete remission between episodes. Outcomes of the analyses are depressive symptoms, associated consequences, adverse events, and study discontinuation. Only randomized controlled trials will be considered.</p> <p>Discussion</p> <p>Given the high prevalence and serious consequences of chronic depression and a considerable amount of existing primary studies addressing the effectiveness of different treatments the present systematic review may be of high relevance. Special attention will be given to the use of current methodological standards. Findings are likely to provide crucial information that may help clinicians to choose the appropriate treatment for chronically depressed patients.</p
