The accumulation of CGRP in the synaptic cleft and its presynaptic activity may induce posttetanic potentiation of MEPP amplitude due to CGRP-stimulated acetylcholine loading into vesicles and subsequent increase of quantal size.Background In 2017, the World Health Organization published "Medication Without Harm, WHO Global Patient Safety Challenge," to reduce patient harm caused by unsafe medication use practices. While the five objectives emphasise the need to create a framework for action, engaging key stakeholders and others, most published research has focused on the perspectives of health professionals. The aim was to explore the views and experiences of decision-makers in Qatar on organisational safety culture, medication errors and error reporting. Method Qualitative, semi-structured interviews were conducted with healthcare decision-makers (policy-makers, professional leaders and managers, lead educators and trainers) in Qatar. Participants were recruited via purposive and snowball sampling, continued to the point of data saturation. The interview schedule focused on error causation and error prevention; engendering a safety culture; and initiatives to encourage error reporting. Interviews were digitally recorded, transcribed and independently analysed by two researchers using the Framework Approach. Results From the 21 interviews conducted, key themes were the need to promote trust within the organisation through articulating a fair blame culture; eliminate management, professional and cultural hierarchies; focus on team building, open communication and feedback; promote professional development; and scale-up successful initiatives. There was recognition that the current medication error reporting processes and systems were suboptimal, with suggested enhancements in themes of promoting a fair blame culture and open communication. Conclusion These positive and negative aspects of organisational culture can inform the development of theory-based interventions to promote patient safety. Central to these will be the further development and sustainment of a "fair" blame culture in Qatar and beyond.Background The COVID-19 pandemic, declared by WHO on March 13, 2020, had a major global impact on the healthcare system and services. In the acute phase, the presence of the SARS-CoV-2 virus in the aerodigestive tract limited activities in the gastroenterology clinic and procedures to emergencies only. Motility and function testing was interrupted and as we enter the recovery phase, restarting these procedures requires a safety-focused approach with adequate infection prevention for patients and healthcare professionals. Methods We summarized knowledge on the presence of the SARS-CoV-2 virus in the aerodigestive tract and the risk of spread with motility and functional testing. We surveyed 39 European centers documenting how the pandemic affected activities and which measures they are considering for restarting these measurements. We propose recommendations based on current knowledge as applied in our center. Results Positioning of catheters for gastrointestinal motility tests carries a concern for aerosol-borne infection of healthcare workers. The risk is low with breath tests. The surveyed centers stopped almost all motility and function tests from the second half of March. The speed of restarting and the safety measures taken varied highly. Conclusions and inferences Based on these findings, we provided recommendations and practical relevant information for motility and function test procedures in the COVID-19 pandemic era, to guarantee a high-quality patient care with adequate infection prevention.This study investigated the influence of the rotation of innominate bone on anterior pelvic plane (APP) tilt, the angle formed by the APP, and coronal plane of the body to determine whether the provision of proper information about the sagittal balance of the body by the value of the APP tilt (APPT). selleck chemical In total, 244 patients (171 females, 73 males) who were candidates for total hip or knee arthroplasty, periacetabular osteotomy, or shelf arthroplasty were included. The rotational angle of the innominate bone was quantified using computed tomography images at the level of the anterior superior, and anterior inferior iliac spine, and ischiopubic portion. Clustering analysis was performed to identify subtypes of innominate bone rotation. High, intermediate, and low internal rotational alignment groups were identified in females, characterized by rotational angles. Males were treated as one group, and no intergroup differences were observed in sacral slope (SS) and pelvic incidence. However, intergroup differences in APPT were found, indicating a variation in APPT irrespective of sagittal body balance. A negligible relationship between SS and APPT was observed in the high-internal-rotation group, intermediate-internal-rotation group, and male group, whereas a moderate correlation found in the low-internal-rotation group (r = .59). The results could suggest surgeons that the value of the APPT provides no information on the sagittal balance; therefore, it may be ignored for acetabular component positioning during preoperative planning for total hip arthroplasty.Previous studies have shown that adult congenital heart disease (ACHD) is associated with high early post-transplant mortality but improved long-term survival in comparison to the overall heart transplant population. We aimed to evaluate survival outcomes of ACHD in adult transplant recipient patients as specifically compared to ischemic (ICM) and dilated cardiomyopathy (DCM) groups. Adult heart transplant recipients between 2004 and 2014 were identified from the ISHLT registry. We used Kaplan-Meier analysis to evaluate overall survival, 1-year survival and 1-year conditional survival among etiology groups and multivariable Cox proportional hazard (PH) models to assess the association between etiology of cardiomyopathy and 1-year and long-term all-cause mortality and cause-specific mortality. We included 30,130 heart transplant recipients. One-year survival was 78.3% in ACHD, 84.3% in ICM and 86.2% in DCM patients (p less then 0.001). By multivariable analysis, during first post transplant year, ACHD and ICM patients were at significantly higher mortality risk than DCM.
