Near-infrared spectroscopy (NIRS) has been widely used in cardiac surgery to monitor cerebral oxygen supply. Poly-D-lysine The initiation and perioperative management of cardiopulmonary bypass (CPB) constitute critical events in modifying the normal physiology of adequate blood and oxygen supply to the brain. First, little is known about how frequent NIRS is really used. Second, there are varying practices on how to initiate CPB. We therefore conducted a survey in Germany to get an idea of NIRS usage in cardiac surgery for the duration of initiation of CPB protocols. A web-based e-mail survey using commercial SurveyMonkey® (SurveyMonkey, San Mateo, CA) software was conducted in August 2017 including all German cardiac surgery centers. About 75% of the perfusion departments do not use NIRS as a standard monitoring device. It is usually reserved for clinical scenarios where cerebral perfusion might be impaired such as aortic arch surgery or carotid artery stenosis. Only one-third of the departments use a standardized duration of initiation of CPB despite a common belief of potential harm with fast initiation. The usual applied time to initiate CPB ranges from 30 to 120 seconds. Our survey revealed that the NIRS technology is only used in specific types of cardiac surgery to this date. In addition, there is a clear need for scientific studies on how to initiate CPB in the best way for the patient.Systemic anticoagulation with heparin during cardiopulmonary bypass (CPB) should be neutralized by protamine administration to restore normal hemostasis. However, protamine has potentially serious side effects and excessive protamine can cause increased postoperative bleeding. Thus, our goal is to appropriately dose protamine at the completion of CPB to neutralize heparin so that neither residual heparin nor excessive protamine is present. We performed a retrospective study of 216 patients who underwent cardiac surgery to search for a safe minimum protamine dose (PD) when measuring heparin concentration (HC). In addition, we developed a formula to determine PD using total heparin dose (THD) and CPB time without measuring HC. When protamine-to-heparin ratio (P-to-H) is set at 1 mg protamine to 100 international unit (IU) heparin in HMS Plus Hemostasis Management System (HMS), we determined that 75% of the calculated total PD is a safe minimum PD to sufficiently neutralize circulating heparin after CPB. On average, this translates into either .37 mg protamine/100 IU heparin of THD or .54 mg/100 IU of the first heparin bolus. The formula we developed to calculate PD without measuring HC can provide a PD that strongly agrees with the safe minimum PD when measuring HC. The safe minimum PD to neutralize circulating heparin after CPB can be significantly lower than conventional dosing practices. Reduction of PD may decrease the risk of postoperative bleeding and protamine-related adverse events. Based on our data, we decreased P-to-H in HMS to examine whether it is possible to reduce PD further than the safe minimum PD determined in this study.Cell saver blood reinfusion, a blood conservation technique recently available for pediatric use, is typically limited to 6 hours post processing to guard against bacterial contamination. We hypothesize that reinfusion of cell saver blood up to 24 hours post collection in children after cardiac surgery will not increase the incidence of hospital-acquired infections (HAI). The primary aim is to compare incidence of HAI between children receiving cell saver blood ≤6 hours vs. >6 to ≤24 hours from its collection. The secondary aim is to compare mortality and clinical outcomes. Retrospective chart review of children ≤18 years undergoing cardiac surgery with cardiopulmonary bypass (CPB) from 2013 to 2018 when cell saver collection and bedside temperature controlled storage became standard of care. Patients on extracorporeal membrane oxygenation (ECMO) within 48 hours postoperatively and those who did not receive cell saver were excluded. The primary outcome was HAI incidence postoperative days 0-6. Demographic data included diagnosis, surgical severity score, and clinical outcomes. 466 patients, 45% female. No significant between-group differences identified. There was no significant difference in HAI (control 8.5% vs. treatment 8.0%, p = .80) and death (control 7.9% vs. treatment 4.9%, p = .20). Noninferiority testing indicated the treatment group was not statistically inferior to the control group (p = .0028). Kaplan-Meier curve depicted similar status between-group rates of no infection or death; 92% treatment vs. 91% control. Total volume allogeneic red blood cell transfusion (allogeneic blood transfusion [ABT]) up to 24 hours postoperatively was significantly less in the treatment group, p 6 to ≤24 hours post collection. Treatment subjects received significantly less volume of ABT. Considering the risks of ABT, these findings support cell saver blood reinfusion up to 24 hours post collection.A critical factor affecting the accuracy of Computational Fluid Dynamic (CFD) simulations and the time required to conduct them is construction of the computational mesh. This study aimed to evaluate the relatively new polyhedral mesh style for simulating aerosol deposition in the upper conducting airways compared with established meshing techniques and experimental data. Hexahedral and polyhedral mesh solutions were compared in two benchmark geometries 1) a 90°-bend with flow characteristics similar to the extrathoracic airways of an adolescent child, and 2) a double bifurcation representing bifurcations B3-B5 in an adult. Both 4-block and 5-block hexahedral meshes were used in the 90°-bend to capture the potential of fully-structured hexahedral meshes. In the 90°-bend, polyhedral elements matched polydisperse in vitro deposition data with 20% relative error (RE; averaged across the particle sizes considered), which is an improvement on the accuracy of the 4-block hexahedral mesh (35% RE) and is similar to tsol dosimetry.Professor Harald zur Hausen, "father of human papillomavirus (HPV) vaccination" turned 85 years old this year. To mark the occasion, a retrospective look at the introduction of HPV vaccination 14 years ago is presented, highlighting the resistance that accompanied the early years of this beneficial vaccination. Even from an early stage vaccination for girls was included in the standard vaccination program of the Standing Commission on Vaccination (STIKO) in 2007 but it was not until 11 years later that it was recommended for boys as well. At around 50%, vaccination rates in both groups in Germany remain too low compared with other countries with school vaccination programs. Yet there are no longer any scientific doubts about HPV vaccination, which has been shown to be safe and effective in studies worldwide. Not only the reduction of precancerous lesions but also of cervical cancers could be shown in real-life studies in addition to the strong reduction of cases of condylomata acuminata in the vaccinated individuals, which is why the World Health Organization (WHO) has declared the elimination of cervical cancer by building population immunity as a vaccination goal. To this end, further efforts should be made to increase vaccination rates in Germany, which was also included in a corresponding appeal at the Conference of Health Ministers in June 2021.This paper challenges geographers to examine the lucrative, but vastly understudied, global supplementary education sector (e.g. private tuition; learning centres; cram schools). It marks a break from research in Geographies of Education on locational, socio-cultural and political-economy issues, by concentrating directly on the economic geography of this metaphorically monikered 'shadow education' sector. Centred on the first wave of the coronavirus pandemic, the paper's aim is to investigate the impact of COVID-19 on the economic vitality, business spatiality and societal value of private tuition in England. Methodologically, it utilises in-depth interviews with tutors providing one-to-one instruction in English, maths or science in the regionally-differentiated tuition market. The findings demonstrate business vitality was impacted COVID-19 related disruption to schooling produced a profound economic shock for the tuition industry, though new opportunities also emerged from the crisis. Business spatiality was fundamentally rewritten, not only in terms of delivery but also as local markets became national ones. The social value of the industry was drawn into question, as the service was both vital and regressive in its distribution. In conclusion, the paper argues geographers of education must (i) Embrace research on supplementary education in its own right and as it articulates with state education provision; (ii) Pursue economic analyses which consider both how markets work to produce unequal outcomes for potential consumers, and how they emerge as a space of educational entrepreneurship for those seeking to make a living; and (iii) Urgently examine how the coronavirus pandemic is rewriting processes across the education system.The COVID-19 pandemic has highlighted the vulnerability of specific population sections, with regards to economic and work conditions, mental and physical well-being, and context-based factors, emphasizing the need for timely policy measures aimed at counteracting the Italian economic framework's fragility-which poorly adapts to unexpected circumstances. Identifying the most vulnerable groups is, therefore, essential with a view to carrying out targeted measures. Concerning University, the economic downturn caused by COVID-19 could likely result in a decrease in enrollments to both the first and further years of study, with significant consequences on the future of students and the system as a whole. The class of students is of great interest, as it is made up of individuals differing from each other in many ways. Our investigation is aimed at observing anxiety levels filtering the perception of one's anxiety state in a highly stressful time such as the pandemic from the usual anxiety levels. This evaluation allows us to evaluate the similarity of individual behaviors during the lockdown period with those from the previous period.Global responses to COVID-19 will impact on delivery of the 17 Sustainable Development Goals by 2030, creating large uncertainties just at the time efforts need to be accelerated. This paper explores how COVID-19 could impact the success of meeting the targets with priority given to the four 'foundational' goals SDG 1 No Poverty; SDG3 Good Health; SDG 14 Life Below Water and SDG 15 Life on Land as these are critical in maintaining a healthy human and environmental resource base on which progress towards all goals can be built. A scenario analysis examines futures across a spectrum in which i) social and health imperatives (lives) dominate, to ii) where economic imperatives (livelihoods) take precedence. Similarly levels of international co-operation are considered ranging from international recognition of urgent global agendas to fragmentation due to the isolation of individual states around national priorities. These give rise to 4 scenarios a) Global Well-being Prioritized b) World Trade Recovers c) Poverty Gaps Widen c) Earth Systems in Danger and the likelihood of achieving the foundational SDGs in each is discussed.
