Objective To compare the clinical efficacy between robot‐assisted minimally invasive transforaminal lumbar interbody fusion (robot‐assisted MIS‐TLIF) and traditional open TLIF surgery in the treatment of lumbar spondylolisthesis. Methods According to the inclusion and exclusion criteria, 48 cases with lumbar spondylolisthesis who received surgical treatment from June 2016 to December 2017 in the spinal surgery department of Beijing Jishuitan Hospital were analyzed in this study, including 23 patients who received robot‐assisted MIS‐TLIF and 25 patients who received traditional open TLIF surgery. The two groups were compared in terms of pedicle screw accuracy evaluated by Gertzbein‐Robbins classification on postoperative computed tomography (CT), operation time, blood loss, postoperative drainage, hospitalization, time to independent ambulation, low back pain evaluated by visual analog scale (VAS), lumbar function evaluated by Oswestry Disability Index (ODI), paraspinal muscles atrophy on magnetic resonance imaging (MRI), and complications. Results Postoperative CT showed that the rate of Grade A screws in the robot‐assisted MIS‐TLIF group was significantly more than that in the open surgery group (χ 2 = 4.698, P = 0.025). Compared with the open surgery group, the robot‐assisted MIS‐TLIF group had significantly less intraoperative blood loss, less postoperative drainage, shorter hospitalization, shorter time to independent ambulation, and lower VAS at 3 days post‐operation (P, Compared to the open surgery group, the robot‐assisted MIS‐TLIF group had achieved a better clinical result of significantly more precise pedicle screw placement, less intraoperative blood loss, less postoperative drainage, shorter hospitalization, shorter time to independent ambulation, lower VAS at 3 days post‐operation, and less paraspinal muscle atrophy.

Hemostasis is a complex physiological process based on the balance between pro-coagulant and anticoagulant systems to avoid pathological bleeding or thrombosis. The changes in standard coagulation tests in liver disease were assumed to reflect an acquired bleeding disorder, and cirrhotic patients were considered naturally anticoagulated. In the light of the new evidence, the theory of rebalanced hemostasis replaced the old concept. According to this model, the hemostatic alteration leads to a unique balance between pro-coagulant, anticoagulant, and fibrinolytic systems. But the balance is fragile and may prone to bleeding or thrombosis depending on various risk factors. The standard coagulation tests [INR (international normalized ratio), platelet count and fibrinogen] only explore parts of the hemostasis, not offering an entire image of the process. Rotational thromboelastometry (ROTEM) and thromboelastography (TEG) are both point of care viscoelastic tests (VET) that provide real-time and dynamic information about the entire hemostasis process, including clot initiation (thrombin generation), clot kinetics, clot strength, and clot stability (lysis). Despite prolonged PT/INR (international normalized ratio of prothrombin time) and low platelet counts, VET is within the normal range in many patients with both acute and chronic liver disease. However, bleeding remains the dominant clinical issue in patients with liver diseases, especially when invasive interventions are required. VET has been shown to asses more appropriately the risk of bleeding than conventional laboratory tests, leading to decrial use of blood products transfusion. Inappropriate clotting is common but often subtle and may be challenging to predict even with the help of VET. Although VET has shown its benefit, more studies are needed to establish cut-off values for TEG and ROTEM in these populations and standardization of transfusion guidelines before invasive interventions in cirrhotic patients/orthotopic liver transplantation.

Background and Aims: Patients with liver disease acquire complex changes in their hemostatic system, resulting in prolongation of the international normalized ratio and thrombocytopenia. Abnormalities in these tests are commonly corrected with fresh frozen plasma (FFP) or platelet transfusions before invasive procedures. Whether these prophylactic transfusions are beneficial and truly indicated is increasingly debated. In this study, we studied ex vivo effects of FFP and platelet transfusions in patients with liver disease-associated hemostatic changes in a real-life clinical setting.Methods: We included 19 patients who were deemed to require prophylactic FFP transfusion by their treating physician and 13 that were prescribed platelet transfusion before a procedure. Hemostatic status was assessed in blood samples taken before and after transfusion and compared with healthy controls (n = 20).Results: Ex vivo thrombin generation was preserved in patients with liver disease before FFP transfusion. Following FFP transfusion, both in and ex vivo thrombin generation significantly increased, as evidenced by a 92% and 38% increase in thrombin-antithrombin and prothrombin fragment 1 + 2 levels, respectively, and a 20% increase in endogenous thrombin potential. Platelet counts increased from 28 [21-41] x 10(9)/L before to 43 [39-64] x 10(9)/L after platelet transfusion (P Conclusions: FFP and platelet transfusion resulted in increased thrombin generation and platelet counts in patients with liver disease, indicating a prothrombotic effect. However, whether all transfusions were truly indicated and had a clinically relevant effect is questionable.

Objectives An epidemiological investigation was conducted into a hepatitis C virus (HCV) outbreak at an outpatients clinic in Seoul (2011-2012). The aim of the study was to analyze the scale of infection, identify the source of infection, and route of transmission to prevent hepatitis C transmission in the future. Methods A retrospective study of the outpatients and health care workers (n = 7,285) in the target outpatient clinic during 2011-2012 was conducted. The history of the study population infection with hepatitis C, electronic medical records, field visits, and health care worker interviews were examined for the period between March 1st, 2006 and March 25th, 2016. The blood samples were collected and tested for anti-HCV antibodies, HCV RNA and HCV gene in 2016. Results The rate of anti-HCV positive results was 4.4% in the study population. The risk factors associated with an anti-HCV positive result were ≥ 10 clinic visits, and receiving an invasive procedure including a nerve block and a block of the peripheral branch of the spinal nerve (p < 0.05). There were 112 HCV RNA positive cases out of 320 anti-HCV positive test result cases, amongst which 100 cases had the dominant HCV genotype 2a which formed either 1 cluster (n = 56) or 2 clusters (n = 25). This result indicated exposure to a high-association infection source. Conclusion Anti-HCV antibodies and genotypic analysis showed an epidemiological association between the outbreak of HCV and invasive procedures performed (2011-2012) at an outpatients clinic in Seoul.

Bleeding and thrombosis are both common complications that patients with advanced liver disease experience. While hemostatic pathways remain largely intact with cirrhosis, this balance can quickly shift in the direction of bleeding or clotting in an unpredictable manner. A growing body of literature is attempting to shed light on difficult scenarios that clinicians often face, ranging from predicting and mitigating bleeding risk in those who need invasive procedures to determining the best strategies to manage both bleeding and thrombotic complications when they occur. Studies examining hemostasis in those with advanced liver disease, however, often include heterogeneous cohorts with varied methodology. While these studies often select a cohort of all types and degrees of cirrhosis, emerging evidence suggests significant differences in underlying systemic inflammation and hemostatic abnormalities among specific phenotypes of liver disease, ranging from compensated cirrhosis to decompensated cirrhosis and acute-on-chronic liver failure. It is paramount that future studies account for these differing disease severities if we hope to address the many critical knowledge gaps in this field.

The performance of surgery and invasive procedures in patients with haemophilia is currently facing new challenges globally. The first is the appropriate application of low-dose protocols of clotting factor concentrates (CFC) achieving adequate perioperative haemostasis in resource constraint environments. The increasing availability of CFC through humanitarian aid programmes allows more invasive surgeries to be performed for which efficacy and safety data should be more widely collected and reported. Second, extended half-life CFC that are increasingly available in many countries represent valuable alternatives to standard half-life products in surgical patients allowing reduced number of infusions and lower consumption, in particular for extended half-life factor IX. Third, in the era of recently introduced non-factor prophylaxis, some minor surgical procedures can now be performed without additional haemostatic treatment, others with few low-dose administrations of CFC or bypassing agents. Additional factor VIII or bypassing treatment has proven to be safe and effective in association with emicizumab for major surgeries, and it was effectively given at low doses in association with fitusiran. No thrombotic complications have been reported in the surgical setting so far. A multidisciplinary team/facility remains crucial to manage major surgery in patients on prophylaxis with these new agents.

Introduction: Breakthrough technologies in the neonatal intensive care unit (NICU) revolutionized neonates’ quality of care. Mother scented simulated hand (MSSH) is an ergonomically designed supportive hand that uses the power of touch to simulate the feeling of being held and cuddled. This study aimed to determine the effect of MSSH on promoting comfort among mechanically ventilated preterm neonates during invasive procedures.Methods: A quasi-experimental, pre-posttest two groups study was carried out in NICU in Smouha, Alexandria. A sample of 62 mechanically ventilated neonates was randomly assigned to two equal groups; the study group wrapped with a warm MSSH during the invasive procedures while the control group received standard care of NICU. Two observers independently rated the neonates’ level of comfort, distress, and pain during endotracheal suctioning (ETS) and heel prick using COMFORTneo scale.Results: It is revealed that the mechanically ventilated neonates had a significantly higher comfort level with MSSH than the standard care during and after both ETS and heal break (p < 0.001 for each). The neonates had significantly lower distress and pain scores when encircled by MSSH during invasive procedures than standard care (p < 0.001 for NRS distress and p < 0.001 for NRS distress).Conclusion: Wrapping the preterm neonates with a warm MSSH promotes comfort and reduces their pain and distress during invasive procedures, especially when their mothers are not physically available.

Objectives The community-based organisation Treatment Action Group has established an online listing of HIV cure-related trials and observational studies derived from trial registries. Our objective was to use the listing as a basis for a landscape analysis of the current status of HIV cure-related clinical research. Methods Trials and observational studies listed as of August 2018 formed the sample set. Survey questions were developed on trial development, trial design, recruitment, enrolment, study completion and dissemination plans. A survey was sent to the contact(s) for each study. Supplemental information was collected from clinicaltrials.gov. The full dataset was then analysed. Results A total of 99 interventional trials and 29 observational studies were included. Diverse interventions are under evaluation, including combinations of experimental candidates. Current studies plan to enrol over 7000 participants. Projected completion dates for ~90% of the sample fell between the fourth quarter of 2018 and the end of 2020. Potential obstacles to enrolment that were reported included concerns over invasive procedures and lack of potential benefit to participants. Data on the sex and ethnicity of enrollees were limited but sufficient to note a significant under-representation of women. Conclusions A considerable amount of HIV cure-related clinical research is under way. The results from these studies, which should help shape the future of the field, will become available over the next 2–4 years. Diversity both geographically and in terms of enrollees remains limited, particularly in terms of the participation of women, a concern that could significantly affect the generalisability of the findings.

International audience; Introduction Emicizumab (Hemlibra (R)) recently became available and requires an adaptation for managing bleeding, suspected bleeding and emergency or scheduled invasive procedures in haemophilia A patients with inhibitor. This implicates a multidisciplinary approach and redaction of recommendations for care that must be regularly adapted to the available data. Aim The following text aims to provide a guide for the management of people with haemophilia A with inhibitor treated with emicizumab in case of bleeding or invasives procedures. Methods The French network on inherited bleeding disorders (MHEMO), the French Reference Centre on Haemophilia (CRH), in collaboration with the French Working Group on Perioperative Haemostasis (GIHP) have been working together to make proposals for the management of these situations. Results Haemostatic treatment and other medications should be given stepwise, according to the severity and location of the bleeding or the risk of bleeding of the procedure as well as the haemostatic response obtained at each step in order to ensure an optimal benefit/risk ratio. Conclusion The lack of data means that it is only possible to issue proposals rather than recommendations.

Introduction: Today, despite of the emphasis on family-based care strategies, there is little understanding of the adult patient's perception of the presence of family members during emergency care and invasive procedures. The aim of this study was to compare the effect of family presence and their training before the presence on the anxiety of patients undergoing invasive nursing procedures in the emergency department. Methods: In this randomized clinical trial, 90 patients undergoing invasive nursing procedures and their family members were selected based on inclusion criteria and allocated randomly in three groups of 30 (with the presence of trained family members, with the presence of untrained family members and without the presence of family members) by minimization method. The data was analyzed by SPSS 16 using Kolmogorov-Smirnov test, Chi-square test, Kruskal Wallis Independent-sample, paired sample t-test, and ANOVA at the significance level of 0.05. Results: The three groups were similar in terms of demographic variables. All three groups had significantly lower anxiety scores in the post-intervention phase than before the intervention (P=0.001). There was no significant difference between the mean and the standard deviation of the patient's anxiety scores before (P=0.131) and after the intervention (P=0.309) in the intergroup comparison. Conclusion: The presence of family members and their training before presence did not reduce the anxiety of patients under nursing invasive procedures. It's necessary that other aspects of family members’ presence during invasive procedures to be considered in future studies.

Background: During the lockdown for COVID-19, a massive decrease in hospital admissions for acute coronary syndrome (ACS) and a drop in air pollution were both detected in Italy. Our aim was to investigate the possible association between these two events at the Province of Terni, one of the most polluted urban and industrial area in Central Italy.Methods: We analyzed data of daily 24-h urban air concentrations of particulate matter (PM)10 and PM2.5 from fixed station monitoring network located in the main city centers of the Terni province, and accesses for ACS at the catheterization laboratory of the Cardiological Hub Center of the Terni University Hospital during lockdown. A comparison was made with data corresponding to the same lockdown time period of years 2019, 2018, and 2017.Results: Invasive procedures for ACS decreased in 2020 (n = 49) as compared with previous years (n = 93 in 2019, n = 109 in 2018, and n = 89 in 2017, p < 0.001). Conversely, reductions in average PM10 (20.7 μg/m3) and PM2.5 (14.7 μg/m3) in 2020 were consistent with a long-term decreasing trend, being comparable to those recorded in 2019 and 2018 (all p > 0.05) and slightly lower than 2017 (p < 0.05). The Granger-causality test demonstrated the lack of association between time-varying changes in air pollution and the number of procedures for ACS.Conclusions: Our results did not support the hypothesis that reduction in invasive procedures for ACS during lockdown was linked to an air cleaning effect. Reasons other than reduced air pollution should be sought to explain the observed decrease in ACS procedures.

Invasive procedures commonly cause recurring pain in preterm infants. Noninvasive pain management is an essential part of nursing intervention in the Neonatal Intensive Care Unit (NICU). The study’s aim is to identify the impact of touch therapy on pain in premature infants undergoing invasive treatments. The method was a quasi- experiment with 63 premature infants. The premature infants were classified into four groups: i) Mother’s touch Therapy (MTT), ii) Mother’s Voice Stimulus (MVS), iii) a combination of MTT and MVS, and iv) routine care. The observed infants’ pain scores were determined through a multiple regression model using the Generalized Estimating Equation (GEE) method. The GEE test showed that the combination of touch and sound therapy significantly reduced pain in premature infants undergoing invasive measures (p

Objective To estimate the risk of fetal loss associated with chorionic villus sampling (CVS) in twin pregnancy, using propensity score analysis. Methods This was a multicenter cohort study of women with twin pregnancy undergoing ultrasound examination at 11–13 weeks' gestation, performed in eight fetal medicine units in which the leadership were trained at the Harris Birthright Research Centre for Fetal Medicine in London, UK, and in which the protocols for screening, invasive testing and pregnancy management are similar. The risk of death of at least one fetus was compared between pregnancies that had and those that did not have CVS, after propensity score matching (1:1 ratio). This procedure created two comparable groups by balancing the maternal and pregnancy characteristics that lead to CVS being performed, similar to how randomization operates in a randomized clinical trial. Results The study population of 8581 twin pregnancies included 445 that had CVS. Death of one or two fetuses at any stage during pregnancy occurred in 11.5% (51/445) of pregnancies in the CVS group and in 6.3% (515/8136) in the non-CVS group (P

Objective To estimate the risk of miscarriage associated with chorionic villus sampling (CVS). Methods This was a retrospective cohort study of women attending for routine ultrasound examination at 11 + 0 to 13 + 6 weeks' gestation at one of eight fetal‐medicine units in Spain, Belgium and Bulgaria, between July 2007 and June 2018. Two populations were included: (1) all singleton pregnancies undergoing first‐trimester assessment at Hospital Clínico Universitario Virgen de la Arrixaca in Murcia, Spain, that did not have CVS (non‐CVS group); and (2) all singleton pregnancies that underwent CVS following first‐trimester assessment at one of the eight participating centers (CVS group). We excluded pregnancies diagnosed with genetic anomalies or major fetal defects before or after birth, those that resulted in termination and those that underwent amniocentesis later in pregnancy. We used propensity score (PS) matching analysis to estimate the association between CVS and miscarriage. We compared the risk of miscarriage of the CVS and non‐CVS groups after PS matching (1:1 ratio). This procedure creates two comparable groups balancing the maternal and pregnancy characteristics that are associated with CVS, in a similar way to that in which randomization operates in a randomized clinical trial. Results The study population consisted of 22 250 pregnancies in the non‐CVS group and 3613 in the CVS group. The incidence of miscarriage in the CVS group (2.1%; 77/3613) was significantly higher than that in the non‐CVS group (0.9% (207/22 250); P, This article's abstract has been translated into Spanish and Chinese.

Although quick diagnosis units (QDU) have become a cost-effective alternative to inpatient admission for diagnosis of potentially serious diseases, the rate of return hospitalizations among evaluated patients is unknown. This study examined the temporal trends in admissions of QDU patients through 15 years. Adult patients referred to QDU from 2004 to 2019 who were hospitalized between the first and last visit in the unit were eligible. Decisions about admissions were mainly based on the Appropriateness Evaluation Protocol and required independent validation by experienced clinicians using a customized tool. The final analysis included 825 patients. Patient characteristics and major reasons for admission were compared each year and linear trends were analyzed. Admission rates decreased from 7.2% in 2004&ndash, 2005 to 4.3% in 2018&ndash, 2019 (p &lt, 0.0001). While a significant increasing trend was observed in the rate of admissions due to cancer-related complications (from 39.5% in 2004&ndash, 2005 to 61.7% in 2018&ndash, 2019, p &lt, 0.0001), those due to anemia-related complications and scheduled invasive procedures experienced a significant downward trend. A likely explanation for these declining trends was the relocation of the unit to a new daycare center in 2013&ndash, 2014 with recovery rooms and armchairs for IV treatments. The facts of this study could help in the provision of anticipatory guidance for the optimal management of patients at risk of clinical complications.

To assess the frequency and safety of procedures performed by advanced practice providers and medical residents in a mixed-bed ICU.Design: A prospective observational study where consecutive invasive procedures were studied over a period of 1 year and 8 months. The interventions were registered anonymously in an online database. Endpoints were success rate at first attempt, number of attempts, complications, level of supervision, and teamwork.Setting: A 33-bedded mixed ICU.Subjects: Advanced practice providers and medical residents.Interventions: Registration of the performance of tracheal intubation, central venous and arterial access, tube thoracostomies, interhospital transportation, and electrical cardioversion.Measurement and main results: A full-time advanced practice provider performed an average of 168 procedures and a medical resident an average of 68. The advanced practice provider inserted significant more radial, brachial, and femoral artery catheters (66% vs 74%, p = 0.17; 15% vs 12%, p = 0.14; 18% vs 14%, p = 0.14, respectively). The median number of attempts needed to successfully insert an arterial catheter was lower, and the success rate at first attempt was higher in the group treated by advanced practice providers (1.30 [interquartile range, 1-1.82] vs 1.53 [interquartile range, 1-2.27], p < 0.0001; and 71% vs 54%, p < 0.0001). The advanced practice providers inserted more central venous catheters (247 vs 177) with a lower median number of attempts (1.20 [interquartile range, 1-1.71] vs 1.33 [interquartile range, 1-1.86]) and a higher success rate at first attempt (81% vs 70%; p < 0.005). The number of intubations by advanced practice providers was 143 and by medical residents was 115 with more supervision by the advanced practice provider (10% vs 0%; p = 0.01). Team performance, as reported by nursing staff, was higher during advanced practice provider procedures compared with medical resident procedures (median, 4.85 [interquartile range, 4.85-5] vs 4.73 [interquartile range, 4.22-5]). Other procedures were also more often performed by advanced practice providers. The complication rate in the advanced practice provider-treated patient group was lower than that in the medical resident group.Conclusions: Advanced practice providers in critical care performed procedures safe and effectively when compared with medical residents. Advanced practice providers appear to be a valuable addition to the professional staff in critical care when it comes to invasive procedures.

Objectives To examine key methodological considerations for using a placebo intervention in randomized controlled trials (RCTs) evaluating invasive procedures, including surgery. Study Design and Setting RCTs comparing an invasive procedure with a placebo were included in this systematic review. Articles published from database inception to December 31, 2017, were retrieved from Ovid MEDLINE, Ovid EMBASE and CENTRAL electronic databases, by handsearching references and expert knowledge. Data on trial characteristics (clinical area, nature of invasive procedure, number of patients and centers) and key methodological (rationale for using placebos, minimization of risk, information provision, offering the treatment intervention to patients randomized to placebo, delivery of cointerventions, and intervention standardization and fidelity) were extracted and summarized descriptively. Results One hundred thirteen articles reporting 96 RCTs were identified. Most were conducted in gastrointestinal surgery (n = 40, 42%) and evaluated minimally invasive procedures (n = 44, 46%). Over two-thirds randomized fewer than 100 patients (n = 65, 68%) and a third were single center (n = 31, 32%). A third (n = 33, 34%) did not report a rationale for using a placebo. Most common strategies to minimize patient risk were operator skill (n = 22, 23%) and independent data monitoring (n = 28, 29%). Provision of patient information regarding placebo use was infrequently reported (n = 11, 11%). Treatment interventions were offered to patients randomized to placebo in 43 trials (45%). Cointerventions were inconsistently reported, but 64 trials (67%) stated that anesthesia was matched between groups. Attempts to standardize interventions and monitor their delivery were reported in n = 7, (7%) and n = 4, (4%) trials, respectively. Conclusion Most placebo-controlled trials in surgery evaluate minor surgical procedures and currently there is inconsistent reporting of key trial methods. There is a need for guidance to optimize the transparency of trial reporting in this area.

Background Placebo‐controlled trials play an important role in the evaluation of healthcare interventions. However, they can be challenging to design and deliver for invasive interventions, including surgery. In‐depth understanding of the component parts of the treatment intervention is needed to ascertain what should, and should not, be delivered as part of the placebo. Assessment of risk to patients and strategies to ensure that the placebo effectively mimics the treatment are also required. To date, no guidance exists for the design of invasive placebo interventions. This study aimed to develop a framework to optimize the design and delivery of invasive placebo interventions in RCTs. Methods A preliminary framework was developed using published literature to: expand the scope of an existing typology, which facilitates the deconstruction of invasive interventions; and identify placebo optimization strategies. The framework was refined after consultation with key stakeholders in surgical trials, consensus methodology and medical ethics. Results The resulting DITTO framework consists of five stages: deconstruct treatment intervention into constituent components and co‐interventions; identify critical surgical element(s); take out the critical element(s); think risk, feasibility and role of placebo in the trial when considering remaining components; and optimize placebo to ensure effective blinding of patients and trial personnel. Conclusion DITTO considers invasive placebo composition systematically, accounting for risk, feasibility and placebo optimization. Use of the framework can support the design of high‐quality RCTs, which are needed to underpin delivery of healthcare interventions., There are challenges in RCTs of invasive interventions with a placebo control. The DITTO framework outlines five stages to optimize invasive placebo design and delivery: deconstruction of the treatment intervention, identification (and removal) of the critical surgical element from the proposed placebo, consideration of risk, feasibility and the role of the placebo in the RCT, and optimization of placebo delivery to ensure effective blinding of patients and trial personnel. DITTO will be useful

Introduction. The aim of this study is to investigate large volume therapeutic paracentesis using either a z-tract or axial (coxial) technique in a randomized controlled trial.Materials and methods. In this randomized, single blind study, patients with cirrhosis undergoing outpatient therapeutic paracentesis were randomized to the z-tract or the modified angular (coaxial) needle insertion technique. Subject and procedure characteristics were compared between the groups with ascites leakage as quantified by need for dressing changes with standardized sized gauze pads as a primary endpoint and subject procedural discomfort, operator preference, and procedure complications as secondary endpoints.Results. 72 paracenteses were performed during the study period: 34 to the z-tract and 38 to the coaxial insertion technique. Following exclusions, a total of 61 paracenteses were analyzed: 30 using the z-tract technique and 31 using the coaxial technique. There were equal rates of post-procedural leakage of ascites between groups (13% in both groups, p = 1.00). Using the visual analog scale (0 - 100), there was a statistically significant increase in the subject reported pain score with the z-tract compared with the coaxial method [26.4 (95% CI 18.7 - 34.1) vs. 17.2 (95% CI 10.6 - 23.8), p = 0.04]. Mean physician rated procedure difficulty (1 - 5) was significantly higher for the z-tract vs. the coaxial technique [2.1 (95% CI 1.6 - 2.6) vs. 1.5 (95% CI 1.2 - 1.8), p = 0.04].Conclusion. When compared to the z-tract technique, the coaxial insertion technique is superior during large volume paracentesis in cirrhosis patients.

Attitudes of physicians toward neonates with poor prognosis greatly influence their decisions regarding the course of treatment and care. The present study aimed to investigate factors contributing to attitudes of medical practitioners toward poor prognosis neonates. This was a cross-sectional, descriptive-analytic study. Questionnaires for assessing subjects’ attitudes toward care of very poor prognosis neonates were administered to all neonatologists, pediatricians, neonatology assistants, and pediatric residents (a total of 88 individuals) working in the NICUs of Imam Khomeini Hospital. Participants’ attitudes were determined through analysis of responses to seven questions on a 5-point Likert scale ranging from “strongly agree” to “strongly disagree”. Presence of anomalies incompatible with an acceptable quality of life, birth weight, gestational age, responses to neonatal diagnostic tests, certain types of diseases, parental marital status and practitioner predictions about patient prognosis were the factors contributing to practitioners’ attitude (P-value < 0.005). However, no significant relationship was found in connection with religious beliefs, socioeconomic status, opinions of consulting physicians, hospital treatment protocols, standards of the Association of Neonatal Physicians, and ethics committee expectations (P-value > 0.005). It can be concluded that the attitudes of practitioners toward intensive care of poor prognosis neonates is determined by the medical condition of the neonate rather than socio-demographic characteristics.

The French Working Group on Perioperative Haemostasis (GIHP)and the French Study Group on Haemostasis and Thrombosis (GFHT)in collaboration with the French Society of Anaesthesia and Intensive Care Medicine (SFAR)drafted up-to-date proposals on the management of antiplatelet therapy for non-elective invasive procedures or bleeding complications. The proposals were discussed and validated by a vote; all proposals could be assigned with a high strength. Emergency management of oral antiplatelet agents (APA)requires knowledge on their pharmacokinetic/pharmacodynamics parameters, evaluation of the degree of the alteration of haemostatic competence and the associated bleeding risk. Platelet function testing may be considered. When APA-induced bleeding risk may worsen the prognosis, measures should be taken to neutralise antiplatelet therapy by considering not only the efficacy of available means (which can be limited for prasugrel and even more for ticagrelor)but also the risks that these means expose the patient to. The measures include platelet transfusion at the appropriate dose and haemostatic agents (tranexamic acid; rFVIIa for ticagrelor). When possible, postponing non-elective invasive procedures at least for a few hours until the elimination of the active compound (which could compromise the effect of transfused platelets)or if possible a few days (reduction of the effect of APA)should be considered., SCOPUS: ar.j, info:eu-repo/semantics/published

Needle-related procedures are often a source of pain, anxiety and fear in young patients. This systematic review aimed to investigate the effectiveness of virtual reality (VR) on reducing pain, fear and anxiety in pediatric patients undergoing needle-related procedures. Pain, anxiety, fear, changes in blood pressure and heart rate as well as satisfaction were evaluated as outcomes during needle-related procedures in VR compared with standard care conditions. A meta-analysis was performed, taking into account online databases. Two authors independently conducted literature searches in December 2020. The last search was conducted in March 2021 from a total of 106 records, 7 met our inclusion criteria. One study was excluded from the meta-analysis due to insufficient data. VR was applied as a distractor during venous access. Statistically significant benefits of using VR were shown in children’s pain scores, where VR significantly decreased symptoms (n = 3204 patients, MD = −2.85; 95% CI −3.57, −2.14, for the Wong–Baker Faces Pain Rating Scale and n = 2240 patients, MD = −0.19; 95% CI −0.58, 0.20, for the Faces Pain Scale—Revised). The analysis of fear, anxiety and satisfaction scores revealed no significant differences between the conditions, as the studies were too heterogeneous to be pooled. Distraction using virtual reality may be an effective intervention for reducing pain in children undergoing needle-related medical procedures. However, further research in the implementation of VR as a distractor for children and adolescents is required, due to the limited research into this field.

Objective: To synthesize the best qualitative evidence regarding the perception of family members, patients and health professionals about family presence during cardiopulmonary resuscitation and invasive procedures. Method: Systematic review with meta-synthesis performed in the databases of Web of Science, Scopus, CINAHL, PsycINFO, LILACS, MEDLINE, Embase and VHL. Articles published between 2010 and 2017 were included and evaluated with use of the Qualitative Data Extraction Instrument. Results: In total, were found 2,391 articles, out of which 26 were selected, and 24 were analyzed. The identified meta-theme was ‘A pendular perspective: different views on family presence during cardiopulmonary resuscitation and invasive procedures’, which is supported by the following themes: Benefits resulting from family presence; Disadvantages and/or limiting factors of family presence; and Context: environmental, sociocultural and care factors influencing the perception of family presence. Conclusion: The perception of family members, patients and professionals about family presence is still controversial. The sensitization of these subjects can potentiate the practice by making it more systematized and qualified. Objetivo: Sintetizar as melhores evidências qualitativas atinentes à percepção de familiares, pacientes e profissionais de saúde sobre a presença da família durante a ressuscitação cardiopulmonar e procedimentos invasivos.

Click to hear Dr Baglin's perspective on the role of the laboratory in treatment with new oral anticoagulants SUMMARY: One of the key benefits of the direct oral anticoagulants (DOACs) is that they do not require routine laboratory monitoring. Nevertheless, assessment of DOAC exposure and anticoagulant effects may become useful in various clinical scenarios. The five approved DOACs (apixaban, betrixaban, dabigatran etexilate, edoxaban and rivaroxaban) have different characteristics impacting assay selection and the interpretation of results. This article provides an updated overview on (i) which test to use (and their advantages and limitations), (ii) when to assay DOAC levels, (iii) how to interpret the results relating to bleeding risk, emergency situations and perioperative management, and (iv) what is the impact of DOACs on routine and specialized coagulation assays. Assays for anti-Xa or anti-IIa activity are the preferred methods when quantitative information is useful, although the situations in which to test for DOAC levels are still debated. Different reagent sensitivities and variabilities in laboratory calibrations impact assay results. International calibration standards for all specific tests for each DOAC are needed to reduce the inter-laboratory variability and allow inter-study comparisons. The impact of the DOACs on hemostasis testing may cause false-positive or false-negative results; however, these can be minimized by using specific assays and collecting blood samples at trough concentrations. Finally, prospective clinical trials are needed to validate the safety and efficacy of proposed laboratory thresholds in relation to clinical decisions. We offer recommendations on the tests to use for measuring DOACs and practical guidance on laboratory testing to help patient management and avoid diagnostic errors. ispartof: Journal of Thrombosis and Haemostasis vol:16 issue:2 pages:209-219 ispartof: location:England status: published

Our objectives were to determine whether procedural pain and glucose exposure are associated with altered structural and functional brain development differently in preterm males and females, and neurodevelopment at 18-month corrected age. Fifty-one very preterm neonates (22 males; median [interquartile range] gestational age 27.6 [2.0] weeks) underwent 3 serial scans including T1-weighted and resting-state functional magnetic resonance imaging (MRI) at median postmenstrual weeks: 29.4, 31.9, and 41.1. Thalamus, basal ganglia, and total brain volumes were segmented. Functional resting-state MRI data were extracted from the independent-components maps. Pain was operationalized as the total number of neonatal intensive care unit administered invasive procedures. Neurodevelopmental outcomes at 18-month corrected age were assessed with the Bayley Scales of Infant Development, second edition. Generalized estimating equations assessed the association of pain and glucose exposure with brain structural and functional development. More invasive procedures were independently associated with slower growth of thalamic (P , 0.001), basal ganglia (P 5 0.028), and total brain volumes (P 5 0.001), particularly in females. Similar relationships were observed between glucose exposure and brain volumes. Functional connectivity between thalamus and sensorimotor cortices was negatively associated with number of invasive procedures. Greater procedural pain and higher glucose exposure were related to poorer neurodevelopmental outcomes. These findings suggest that structural and functional brain development is vulnerable to procedural pain. Glucose used for analgesia does not appear to mitigate the adverse impact of pain on brain development. The vulnerability of brain development in females towards early pain is distinct from other neonatal morbidities. The link between pain and glucose with neurodevelopment suggests that these factors have long-lasting impact.

Mastocytosis is a neoplastic disease originating from tissue infiltration by transformed mast cells. The diagnosis requires a high grade of suspicion due to the large variety of presenting symptoms. The World Health Organization classification recognizes localized (cutaneous) and systemic forms of the disease, with these forms showing different degrees of aggressiveness. Mastocytosis is often a multiorgan disease, and its correct management requires a multidisciplinary team of experienced consultants to provide overall patient care. Bone marrow evaluation by molecular analyses, skeleton X-ray and abdominal scan together with allergologic and dermatologic evaluation constitute the essential diagnostic work-up for adult patients with mastocytosis. As clinical situations vary, treatment options range from the use of drugs to treat the symptoms, such as anti-H1 receptors and steroids, to UV irradiation, which is overwhelmingly used in patients with cutaneous mastocytosis (CM) or indolent systemic mastocytosis, to cytoreductive treatment to control life-threatening symptoms or organ damage in the more aggressive forms of the disease. Prognosis also widely differs among patients diagnosed with mastocytosis, with the spectrum ranging from an almost normal life expectancy for those with CM and to less than 1-year median overall survival for those with mast cell leukemia.

IntroductionPatients with Von Willebrand disease (VWD) are regularly treated with VWF-containing concentrates in case of acute bleeding, trauma and dental or surgical procedures.AimIn this multicentre retrospective study, current perioperative management with a von Willebrand factor (VWF)/Factor VIII (FVIII) concentrate (Haemate((R)) P) in patients with VWD was evaluated.Patients/MethodsPatients with VWD undergoing minor or major surgery between 2000 and 2015, requiring treatment with a VWF/FVIII concentrate (Haemate((R)) P), were included. Achieved VWF activity (VWF:Act) and FVIII during FVIII-based treatment regimens were compared to predefined target levels in national guidelines.ResultsIn total, 103 patients with VWD (148 surgeries) were included: 54 type 1 (73 surgeries), 43 type 2 (67 surgeries) and 6 type 3 (8 surgeries). Overall, treatment resulted in high VWF:Act and FVIII levels, defined as 0.20IU/mL above predefined levels. In patients with type 1 VWD, respectively, 65% and 91% of trough VWF:Act and FVIII levels were higher than target levels. In patients with type 2 and type 3 VWD, respectively, 53% and 57% of trough VWF:Act and 72% and 73% of trough FVIII levels were higher than target level. Furthermore, FVIII accumulation over time was observed, while VWF:Act showed a declining trend, leading to significantly higher levels of FVIII than VWF:Act.ConclusionHigh VWF:Act and accumulation of FVIII were observed after perioperative FVIII-based replacement therapy in patients with VWD, both underlining the necessity of personalization of dosing regimens to optimize perioperative treatment.

Direct oral anticoagulants (DOACs) have been licensed worldwide for several years for various indications. Each year, 10-15% of patients on oral anticoagulants will undergo an invasive procedure and expert groups have issued several guidelines on perioperative management in such situations. The perioperative guidelines have undergone numerous updates as clinical experience of emergency management has increased and perioperative studies including measurement of residual anticoagulant levels have been published. The high inter-patient variability of DOAC plasma levels has challenged the traditional recommendation that perioperative DOAC interruption should be based only on the elimination half-life of DOACs, especially before invasive procedures carrying a high risk of bleeding. Furthermore, recent publications have highlighted the potential danger of heparin bridging use when DOACs are stopped before an invasive procedure. As antidotes are progressively becoming available to manage severe bleeding or urgent procedures in patients on DOACs, accurate laboratory tests have become the standard to guide their administration and their actions need to be well understood by clinicians. This review aims to provide a systematic approach to managing patients on DOACs, based on recent updates of various perioperative guidance, and highlighting the advantages and limits of recommendations based on pharmacokinetic properties and laboratory tests., SCOPUS: re.j, info:eu-repo/semantics/published

Preoperative hemostasis testing may have limited use in patients with liver disease, and an abnormal platelet count, prothrombin time, activated partial thromboplastin time, and fibrinogen level should not trigger prophylactic transfusion of blood product components.

Summary Background Acinetobacter baumannii is considered a leading cause of nosocomial bloodstream infections in intensive care units (ICUs), but there is disagreement as to whether certain invasive ICU procedures increase the risk of this infection. To help address this question, we performed a systematic review of the literature on whether previous catheterization (central venous, arterial, and urinary), mechanical ventilation, nasogastric tube use, and abdominal or thoracic drainage are associated with the development of A. baumannii nosocomial bacteremia in ICUs. Methods Two reviewers searched PubMed, EMBASE, and Medline for the period January 1999 to February 2013. For each of seven invasive procedures, patients in the included studies were classified into two groups: those who had previously undergone that procedure and those who had not. The frequencies of A. baumannii nosocomial bacteremia were determined for each group. Results Five studies were included in the meta-analysis: three provided data for thoracic drainage, four for abdominal drainage, and five for the other invasive procedures. The following prior interventions were associated with an elevated risk of A. baumannii nosocomial bacteremia: mechanical ventilation (odds ratio (OR) 4.79, 95% confidence interval (CI) 3.09–7.43), central venous catheterization (OR 6.25, 95% CI 2.58–15.11), urinary catheterization (OR 2.55, 95% CI 1.49–4.36), and nasogastric tube use (OR 4.70, 95% CI 2.79–7.91). Conclusions Available evidence suggests that prior central venous or urinary catheterization, mechanical ventilation, and nasogastric tube use are associated with a higher risk of A. baumannii nosocomial bacteremia in the ICU.

Background Eltrombopag is an oral thrombopoietin receptor agonist that stimulates thrombopoiesis and shows higher exposure in East Asian patients than in non-Asian patients. We evaluated the pharmacokinetics, efficacy, and safety of eltrombopag in Japanese patients with thrombocytopenia associated with chronic liver disease (CLD). Methods Thirty-eight patients with CLD and thrombocytopenia (platelets

Background Reducing the false-positive risk in breast cancer screening is important. We examined how the screening-protocol and women's characteristics affect the cumulative false-positive risk. Methods This is a retrospective cohort study of 1 565 364 women aged 45–69 years who underwent 4 739 498 screening mammograms from 1990 to 2006. Multilevel discrete hazard models were used to estimate the cumulative false-positive risk over 10 sequential mammograms under different risk scenarios. Results The factors affecting the false-positive risk for any procedure and for invasive procedures were double mammogram reading [odds ratio (OR) = 2.06 and 4.44, respectively], two mammographic views (OR = 0.77 and 1.56, respectively), digital mammography (OR = 0.83 for invasive procedures), premenopausal status (OR = 1.31 and 1.22, respectively), use of hormone replacement therapy (OR = 1.03 and 0.84, respectively), previous invasive procedures (OR = 1.52 and 2.00, respectively), and a familial history of breast cancer (OR = 1.18 and 1.21, respectively). The cumulative false-positive risk for women who started screening at age 50–51 was 20.39% [95% confidence interval (CI) 20.02–20.76], ranging from 51.43% to 7.47% in the highest and lowest risk profiles, respectively. The cumulative risk for invasive procedures was 1.76% (95% CI 1.66–1.87), ranging from 12.02% to 1.58%. Conclusions The cumulative false-positive risk varied widely depending on the factors studied. These findings are relevant to provide women with accurate information and to improve the effectiveness of screening programs.

Resumen: En las últimas décadas, el modelo de medicina paternalista se ha sustituido por un modelo centrado en el sujeto y sus familiares. En el ámbito de las urgencias pediátricas, este hecho ha conllevado un mayor protagonismo de los padres, especialmente durante la realización de procedimientos invasivos. Numerosos autores han estudiado las ventajas y los inconvenientes de esta nueva práctica, tanto para los sujetos y sus familiares como para el personal sanitario. Dada la escasa bibliografía española, se revisó la literatura médica publicada hasta el momento y se analizaron los posibles beneficios y perjuicios para el sujeto y sus familiares, así como la posición de los profesionales sanitarios. Abstract: Over the last decades, health care has been moving away from the paternalistic model, to one of family-centered care. In the pediatric emergency department, this new trend has led to parents playing a larger role in the health care of children, particularly during invasive procedures and/or resuscitation. Despite the increased attention to family presence, it remains a controversial topic, especially among emergency medical staff. Several studies have been performed that look at the advantages and disadvantages of this new way of conceiving child health care. To our knowledge, there is only one Spanish article on this topic, which is the reason why we performed a literature review on family presence in the emergency department.

Objetivo. Valorar la seguridad y efectividad de un protocolo de sedoanalgesia para procedimientos invasivos en pacientes pediátricos. Diseño. Estudio prospectivo observacional. Ámbito. Una unidad de medicina intensiva pediátrica (UMIP) de un hospital de tercer nivel. Pacientes. 110 niños sometidos a procedimientos invasivos bajo sedoanalgesia durante un período de 3 años. Intervenciones. Se aplicó un protocolo de sedoanalgesia para los procedimientos invasivos con: fentanilo (1-2 mcg/kg con dosis máxima de 100 mcg para la primera dosis y 50 mcg para siguientes) y propofol (1-2 mg/kg con dosis máxima de 100 mg para la primera dosis y 50 mg para las siguientes). El objetivo fue alcanzar un grado III-IV en la escala de Ramsay modificada y amnesia del procedimiento. Variables principales. a) Los tiempos hasta: sedoanalgesia, recuperación, duración del procedimiento y estancia en la unidad de Medicina Intensiva Pediátrica; b) dosis medias de los fármacos administrados; c) grado de sedoanalgesia y amnesia y d) efectos adversos. Resultados. Se realizaron 500 sedoanalgesias para 634 procedimientos a 110 niños. La patología más frecuente fue la onco-hematológica (91%), siendo la punción lumbar con tratamiento intratecal el procedimiento más realizado: (48,5%). No recordaron el mismo el 96,8% de los pacientes, consiguiéndose sedoanalgesia óptima en el 93,4%. Estos pacientes, respecto a aquellos con un menor grado de sedoanalgesia, presentaron un descenso de la presión arterial sistólica (88 ± 19 frente a 98 ± 14 mmHg; p < 0,001), de la frecuencia cardíaca (88 ± 17 frente a 91 ± 25 lpm; p < 0,05) y de la frecuencia respiratoria (19 ± 6 frente a 23 ± 11 respiraciones por minuto; p < 0,05). El tiempo medio hasta la sedoanalgesia fue de 4,62 ± 3,69 minutos y el tiempo de estancia en la UMIP fue de 41,8 ± 19 minutos. La incidencia de complicaciones fue del 6,6% (apnea, hipotensión, bradicardia), resolviéndose éstas con ventilación manual y/o expansión de volumen. Conclusiones. El protocolo de sedoanalgesia para procedimientos invasivos consiguió una sedoanalgesia óptima con amnesia del procedimiento en la casi totalidad de los casos. La monitorización y las medidas de estabilización permitieron el control de las complicaciones presentadas. Objective. Apply a sedoanalgesic (SA) protocol for invasive procedures (PI) in pediatric patients and evaluate its effectiveness and safety. Design. Prospective observational study. Scope. Pediatric Intensive Care Unit (PICU) of third level hospital. Patients. A total of 110 children subjected to invasive procedures under sedoanalgesia with propofol and fentanyl. Intervention. Sedoanalgesic protocol for invasive procedure was applied with: fentanyl (1-2 mcg/kg with maximum dose of 100 mcg for first dose and 50 mcg for the next) and propofol (1-2 mg/kg with maximum of 100 mg for first dose and 50 mg for the next). The objective was to reach III-IV sedoanalgesic grade for modified Ramsay scale and amnesia related to invasive procedure. Main endpoints. a) time to sedoanalgesia and recovery, length for invasive procedure and stay in the Pediatric Intensive Care Unit; b) mean dose of drug; c) sedoanalgesic grade and amnesia related to invasive procedure and d) adverse events. Results. Five hundreds SA were made for 634 IP in 110 children. The most common conditions were oncohematologics (91%), the spinal tap for intrathecal treatment was the most frequent IP (48.5%). Most of the patients (96.8%) did not recall the procedure and an optimum SA was obtained in 93.4%. Patients profoundly sedated presented a significant fall of systolic arterial pressure (88 ± 19 vs 98 ± 14 mmHg, p < 0.001) compared to those with minor SA level, as well as heart rate (88 ± 17 vs 91 ± 25 bpm, p < 0.05) and respiratory rate (19 ± 6 vs 23 ± 11 bpm, p < 0.05). Mean time to reach adequate sedation was 4.62 ± 3.69 minutes and stay time in PICU 41.8 ± 19. Complication incidence was 6.6% (apnea, hypotension, bradycardia), these were resolved with manual ventilation and/or volume expansion. Conclusions. SA protocol reached its goal of: a) effectiveness: SA achieved was optimal, with amnesia of the procedure in almost all patients and b) safety: complications were controlled due to monitorization and stabilization measurements.

Simple Summary The Fawn Hooded (FH) rat population is commonly used in biomedical research. It is widely acknowledged that the FH rat has a bleeding disorder, which may lead to abundant bleeding. However, the clinical consequences of this bleeding disorder have not been described in current literature. During our study, surgical procedures on FH rats led to an unanticipated loss of animals due to abundant bleeding. Adjustments made to minimize the impact of this disorder in animals undergoing invasive procedures are described. It is strongly recommended to take the bleeding diathesis into account when performing invasive procedures in FH rats and to apply the described refinements. Abstract The Fawn hooded (FH) rat is commonly used in biomedical research. It is widely acknowledged that the FH rat has a bleeding disorder; leading to abundant bleedings. Although this bleeding disorder is investigated to model the storage pool defect; its impact on commonly performed invasive laboratory procedures has not yet been described. Our research group experienced clinically significant consequences of this bleeding disorder following invasive procedures (including intraperitoneal injections and neurocranial surgery) in the Rjlbm: FH stock. The clinical consequences of the surgical and anesthetic protocols applied; are described including the subsequent procedural refinements applied to minimize the impact of this disorder. It is strongly recommended to take the bleeding diathesis into account when performing invasive procedures in FH rats and to apply the suggested refinement of procedures.

The aim of this study was to evaluate the efficacy of clinical strategies to reduce nosocomial sepsis (NS) in extremely low birth weight infants (ELBWI) less than 1,000 g. Data from the period before (P1, 1995-2000) and after (P2, 2001-2002) implementation of the strategies were collected and analyzed. The intervention strategies included restriction of antibiotic therapy, less use of invasive procedures such as umbilical vessel catheterization and endotracheal intubation, establishment of guidelines for hand-washing, infant handling, and central intravascular line management. NS was defined as positive blood cultures in symptomatic patients after the third day of life with the use of antibiotics for more than 5 days. Although the gestational age (GA) and birth weight (BW) were significantly lower in P2 (GA 26.7 +/-2.1 wk; BW 796 +/-130 g) compared to P1 (GA 27.2 +/-1.6 wk; BW 857 +/-121 g), the incidence of NS decreased significantly from 70% (69/99) in P1 to 17% (24/71) in P2 with the implementation of the intervention strategies. The coagulase negative Staphylococcus infection was also significantly reduced from 34% in P1 to 11% in P2. The implementation of the clinical strategies was quite effective in reducing the incidence of NS in ELBWI.

Objectives Competency in practical skills is an important aspect of training for medical doctors. This questionnaire survey aimed to investigate if the current Foundation Year trainees have performed several practical procedures of importance and their level of confidence in carrying them out unsupervised. Design Questionnaire study. Setting Five National Health Service hospitals in England. Participants A total of 103 Foundation Year trainees responded to the survey (73 FY1s; 30 FY2s). Main outcome measures Percentage of trainees who have performed these skills and their average level of confidence. Results The percentage of trainees who have performed these skills and their average level of confidence (scale of 1 to 5) are as follows: intubation (32%, 1); chest drain (33%, 1); central line (26%, 1); femoral line (23%, 1); peripheral line (28%, 1); lumbar puncture (64%, 3); ascitic tap (57%, 3). Only 25% of the trainees have attended certified training courses on these skills during their Foundation Year training. More than half of these trainees (73%) found the courses very useful. Ninety-two per cent of trainees who did not attend practical skill courses are very interested to attend them. All the trainees agreed that these courses should be available for all the Foundation Year doctors, and 92% believe that these courses are most beneficial during the Foundation Year 1 training. Conclusion Most Foundation Year trainees have low confidence and exposure to these important practical skills. Certified practical skills courses should be made available to the Foundation Year doctors for the benefit of their training. This will also increase the quality of patient care.

Background ICU patients frequently undergo non-life-saving invasive procedures. When patient informed consent cannot be obtained, legal guardianship (LG), often from a close relative, may be required by law. The objective of this cohort study was to investigate the attitudes of LGs of ICU patients regarding the process of decision making for invasive non-life-saving procedures. Methods The study was conducted from May 2009 until June 2010 in general medical/surgical ICUs in two large Israeli medical centers. All 64 LGs who met the study criteria agreed to participate in the study. Three questionnaires were administered: a demographic data questionnaire, the Family Satisfaction with ICU 34 Questionnaire, and the Attitudes towards the LG Decision Making Process questionnaire, developed by the authors. Results The sample consisted of 64 LGs. Most participants were married (n = 56, 87.5%), male (n = 33, 51.6%), who had either a high school (n = 24, 37.5%) or college (n = 19, 29.7%) education, and were at a mean age of 49.2 (±11.22). Almost all of the procedures performed were tracheotomies (n = 63, 98.4%). About two-thirds of the LGs preferred decisions to be made by the medical staff after discussing options with them (n = 42, 65.6%) and about three-fifths stated that decisions could be made without the need for the appointment of an LG (n = 37, 57.8%). Attitudes towards ease of obtaining information and honesty of information were more positive compared to those of consistency and understanding of information. Conclusions The legal guardianship process requires better communication and more understandable information in order to assist LGs in making decisions for others in at times vague and stressful situations.

Introduction: Critically ill patients are common in emergency medicine, and require expert care to maximize patient outcomes. However, little data is available on the provision of critical care in the ED. The goal of this study is to describe the management of critically ill patients in the ED via a survey of Canadian emergency physicians. Materials and Methods: A survey of attending physician members of CAEP was conducted by email. The survey was developed by the authors and internal validity was established prior to survey deployment. Data on physician demographics, hospital resources, use of invasive procedures, vasopressor/inotropic medications, length of stay in the ED and patient responsibility were assessed. Results: The survey response rate was 22.9%, with the majority of respondents possessing speciality training in EM (73.5%). Respondents indicated that critically ill patients were commonly managed in the ED, with 68.5% reporting >6 critically ill patients per month, and 12.4% indicating > 20 patients per month. Respondents indicated that the majority of critically ill patients remained in the ED for 1-4 hours (70%) after resuscitation, yet 18% remained in the ED for >5 hours. Patients with a “respiratory” etiology were the most common critically ill patient population reported, followed by “cardiovascular”, “infectious” and “traumatic illness”. Direct laryngoscopy was frequently performed (66.9%> 11 in the year prior to the survey) in the year prior to the survey, while other invasive procedures and vasopressor/inotropic medications were utilized less often. EM physicians were responsible for the management of critically ill patients in the ED, even after consultation to an inpatient service, and were often required to provided acute care to critically ill patients admitted to an ICU, yet remaining in the ED prior to transfer (20% reported > 50% of the time). Conclusion: Our survey demonstrates that critically ill patients are common in Canadian ED's, and that EMP's are often responsible to provide care for prolonged period of time. In addition, the use of invasive procedures other then direct laryngoscopy was variable. Further research is warranted to determine the impact of delayed transfer and ED physician management of critically ill patients in the ED.

Stereotactic placement of intracerebral multilead electrodes for chronic EEG recording of seizures or stereoelectroencephalography (SEEG) was introduced 50 years ago at Saint Anne Hospital in Paris, France for the presurgical evaluation of patients with drug-resistant focal epilepsy. SEEG explorations are indicated whenever the noninvasive tests fail to adequately localize the epileptogenic zone (EZ).Currently, approximately 35% of our operated-on children require a SEEG evaluation. Arrangement of electrodes is individualized according to the peculiar needs of each child, to verify a predetermined hypothesis of localization of the EZ based on pre-SEEG anatomo-electro-clinical findings. Multilead intracerebral electrodes are designed to sample cortical structures on the lateral, intermediate, and mesial aspect of the hemisphere, as well as deep-seated lesions. Stereotactic stereoscopic teleangiograms and coregistered 3-D MRI are employed to plan avascular trajectories and to accurately target the desired structures. Pre-SEEG stereotactic neuroradiology and electrode implantation are usually performed in separate procedures. Electrodes are removed once video-SEEG monitoring is completed.Intracerebral electrical stimulations are used to better define the EZ and to obtain a detailed functional mapping of critical cortical and subcortical regions.Surgical morbidity of SEEG is definitely low in children. SEEG-GUIDED RESECTIVE SURGERY: In 90% of evaluated children, SEEG provides a guide for extratemporal or multilobar resections. SEEG-guided resective surgery may yield excellent results on seizures with 60% of patients in Engel's Class I.

Background : Sepsis contributes significantly to newborn deaths in Nigeria. A significant proportion of severe infections in the newborn may be health care-related. Objective: To determine the prevalence, types and risk factors for nosocomial infections in the Special Care Baby Unit of a Nigerian Tertiary Hospital. Method: A cross-sectional survey of consecutively admitted infants aged 0 to 28 days with signs of infections or who developed signs of infection following admission. Infants with or without nosocomial infections were compared for the clinical and laboratory details. Results: Out of 356 infants, 32 (8.9%) had between 1 and 3 nosocomial infections while 48 (13.5%) had community-acquired infections. Half of babies with nosocomial infections were preterm and weighed less than 2kg. A significantly higher proportion of babies with nosocomial infections were inborn (p < 0.000) and stayed longer than 7 days on admission (p = 0.034). Bacteraemia was significantly more frequent among babies with nosocomial infections (p = 0.014) while superficial skin and mucosal infections occurred to similar extents in both groups. Klebsiella and Proteus species were the leading isolates among babies with nosocomial infections. Nasogastric intubation was significantly more frequently performed among babies with nosocomial infections (p = 0.045). Conclusion: The present study revealed that hospital acquired infection is an important cause of morbidity in the newborn unit.

ResumenIntroducciónLa bacteriemia nosocomial es una causa frecuente de infección nosocomial en los recién nacidos admitidos en las unidades de cuidados intensivos neonatales y está asociada con factores de riesgo, reconocidos y no reconocidos, de infección nosocomial. Aún existen pocas evidencias sobre los factores de riesgo de bacteriemia nosocomial en recién nacidos de bajo peso al nacimiento.ObjetivosInvestigar factores de riesgo de bacteriemia nosocomial en neonatos con un peso inferior a 1.500 g ingresados en la unidad de cuidados intensivos neonatal.MétodosSe realizó un estudio prospectivo en recién nacidos de bajo peso al nacimiento (≤ 1.500 g) durante 22 meses. Para determinar la asociación estadística entre la bacteriemia nosocomial y los factores de riesgo perinatales y nosocomiales, se llevó a cabo un análisis bivariante de regresión logística (método de regresión por pasos).ResultadosSe estudió a un total de 72 pacientes con bacteriemia nosocomial y 174 sin ella. La permanencia del catéter umbilical un tiempo mayor o igual a 7 días y la permanencia del catéter periférico arterial durante un día o más resultaron ser los factores independientemente asociados con bacteriemia nosocomial.ConclusiónEl mantenimiento del catéter umbilical más de 7 días, la permanencia del catéter periférico arterial más de 1 día y el peso al nacimiento inferior a 1.500 g fueron factores determinantes de bacteriemia nosocomial. Por la importancia de estas técnicas invasivas como fuente de bacteriemia nosocomial, es preciso revisar su tiempo de permanencia con el objetivo de disminuir la incidencia de bacteriemia nosocomial.AbstractBackgroundNosocomial bloodstream infections occur frequently in Neonatal Intensive Care Units and are associated with recognized and unrecognized risk factors. Little has been published regarding risk factors for bloodstream infections in low birth weight neonates.ObjectiveTo investigate risk factors for bloodstream infection in neonates < 1,500 g admitted at a Neonatal Intensive Care Unit.MethodsA prospective study was undertaken in low birth weight neonates (< 1,500g) during a 22 months period. Bivariant, and logistic regresion (stepwise procedure) analysis was used to determine the significance association of bloodstream infection and perinatal and nosocomial risk factors.ResultsA total of 72 patiens with nosocomial bacteriemia and 147 non bacteriemic patients were studied. Independent risk factors associated with bloodstream infection were birth weight, persistence of umbilical catheter > 7 days and persistence of peripheral arterial catheter > 1 day.ConclusionsThe uses of umbilical catheter > 7 days, peripheral arterial catheter > 1 day and birth weight < 1,500 g were significant determinants of nosocomial bloodstream infection risk. Because of the importance of invasive procedures as a source of nosocomial bloodstream infections, the lines duration needs to be reviewed with the aim of reducing the incidence of blood stream infection.

SummaryDirect oral anticoagulants (DOAs) – inhibitors of thrombin or factor-Xa – are expected to replace vitamin K antagonists in most of their indications. Patients receiving long-term treatment with DOAs are likely to be exposed to elective or emergency surgery or invasive procedures. Owing to the present lack of experience in such conditions, we cannot make recommendations, but only propose perioperative management for optimal safety regarding the risk of bleeding and thrombosis. DOAs may increase surgical bleeding, they have no validated antagonists, they cannot be monitored by simple standardized laboratory assays and their pharmacokinetics vary significantly between patients. Although DOAs differ in many respects, the proposals in the perioperative setting need not be specific to each. For procedures with low haemorrhagic risk, a therapeutic window of 48hours (last administration 24hours before surgery, restart 24hours after) is proposed. For procedures with medium or high haemorrhagic risk, we suggest stopping DOAs 5 days before surgery to ensure complete elimination in all patients. Treatment should be resumed only when the risk of bleeding has been controlled. In patients at high thrombotic risk (e.g. those in atrial fibrillation with a history of stroke), bridging with heparin (low molecular-weight heparin, or unfractionated heparin, if the former is contraindicated) is proposed. In an emergency, the procedure should be postponed for as long as possible (minimum 1–2 half-lives) and non-specific antihaemorrhagic agents, such as recombinant human activated factor VIIa or prothrombin complex concentrates should not be given for prophylactic reversal due to their uncertain benefit-risk.

Background Today more than two million people with Turkish migration background live in Germany making them the largest ethnic minority in the country. Data concerning language skills and the perception of medical information in hospitalised patients with Turkish migration background (T) are scarce. Our study is the first to gather quantitative information on this important subject. Methods T and hospitalised German patients without migration background (G) of our university hospital were prospectively included into a cross-sectional study and completed a questionnaire - each group in the appropriate language (T: Turkish, G: German). Results 121 T and 121 G were included. Groups significantly differed in age (T: 44.9 ± 17.8, G: 56.9 ± 16.7y) and proportion of males (T: 37.2, G: 54.5%) but not regarding the proportion of college graduates (T: 19.3, G: 15.7%). The majority of T was born in Turkey (71%) and is of Turkish nationality (66%). 74% of T speak mainly Turkish at home; however, 73% speak German at work. 74.4% of T self-rated their German linguistic proficiency as “average” or better while 25.6% reported it as “very bad” or “bad”. 10.7% of T need translation in order to pursue everyday activities. T were significantly less satisfied with the physician’s information on disease and estimated to understand significantly less of what the physician told them: 46.3% of T estimated their reception of the physician’s information to be “average” or worse. 43.3% of T had the impression that it would have helped them “much” or “very much” to be aided by an interpreter at the hospital. The information transmitted while giving informed consent to invasive medical procedure was judged to be “mostly” or “completely” sufficient by the majority of T (76%) and G (89.8%). In this setting 37 of 96 T (38.5%) reported being helped by an interpreter – in most cases (64.9%) a family member. Conclusion Although the majority of patients with Turkish migration background have spent most of their lives in Germany (28.94 ± 10.41y) a large part of this population has limited German language skills and difficulties obtaining medical information when hospitalised.
