High success perfect transmission of 1-qubit information using purposefully delayed sharing of non-maximally entangled 2-qubit resource and repeated generalized Bell-state measurements

We propose a new scheme in which perfect transmission of 1-qubit information is achieved with high success using purposefully delayed sharing of non-maximally entangled 2-qubit resource and repeated generalized Bell-state measurements (GBSM). Alice possesses initially all qubits and she makes repeated GBSM on the pair of qubits, consisting of (1) the qubit of information state and (2) one of the two entangled resource qubits (taken alternately) until transmission with perfect fidelity is indicated. Alice then sends to Bob, the qubit not used in the last GBSM and also the result of this GBSM and Bob applies a suitable unitary transformation to replicate exactly the information state. Continued probabilistic transmission with unit fidelity is achieved by changing continuously the generalized Bell basis and also the pair of measured qubits of the collapsed states. We calculate the success probability up to the third repeated attempt of GBSM and plot it with concurrence of the entangled resource state. We also discuss the maximal average fidelity.

Incidence and associated factors of postdural puncture headache for parturients who underwent cesarean section with spinal anesthesia at Debre Tabor General Hospital, Ethiopia; 2019

Introduction and Objective: Postdural puncture headache is one of the most frequent late complications of spinal anesthesia. There are different factors that might predispose for postdural puncture headache. Therefore, the main aim of this study was to assess the incidence of postdural puncture headache and its associated factors for parturients who gave birth by cesarean section under spinal anesthesia. Methods: Hospital-based longitudinal study was conducted on mothers who underwent cesarean section with spinal anesthesia. Descriptive analysis and chi-square test were employed. Bivariable and multivariable logistic regression were used to measure the association of factors with the presence of postdural puncture headache. A p-value of ⩽0.05 was used to decide statistical significance for multivariable logistic regression. Result: A total of 119 parturients were participated in this study. The incidence of postdural puncture headache was 20.2%. According to multivariable logistic regression, having previous spinal anesthesia (adjusted odds ratio = 7.028; 95% confidence interval = 2.377–20.781; p = 0.0001), using 20- and 22-gauge needle (adjusted odds ratio = 4.206; 95% confidence interval = 1.247–14.187; p = 0.021), and repeated attempt (adjusted odds ratio = 4.699; 95% confidence interval = 1.594–13.872; p = 0.05) had statistically significant association with postdural puncture headache. Conclusion: Larger gauge needle size, repeated attempt, and previous spinal anesthesia might increase the incidence of postdural puncture headache.

Reaccessing an occluded radial artery for neuroendovascular procedures: techniques and complication avoidance

BackgroundRadial artery occlusion (RAO) occurs in 1% to 10% of cases following transradial arterial access (TRA) for neuroendovascular procedures. When repeat access is required in patients discovered to have RAO, a transfemoral approach is often used. This study reports experience with repeat TRA procedures at a single center and techniques for reaccessing an occluded radial artery in select patients.MethodsThe electronic records of all patients who underwent multiple neuroendovascular procedures with an attempted TRA as the index procedure at a single center from July 2019 through February 2020 were reviewed.ResultsThere were 656 TRA attempts for diagnostic angiography or intervention from July 2019 through February 2020. A total of 106 patients underwent a repeated attempt at TRA. Techniques for reaccessing an occluded radial artery were implemented halfway through the study period. One hundred patients (94.3%) had a successful second radial catheterization. Six patients required conversion to a transfemoral approach: five for RAO and one for radial branch perforation during the index procedure. After we implemented our techniques for reaccess, four additional patients with RAO successfully underwent TRA. There were no short-term complications, including pain, vessel perforation, forearm hematoma, or hand ischemia, following successful repeat catheterization of a previously occluded radial artery.ConclusionRAO is not an absolute limitation for attempting TRA in patients undergoing repeat catheterization. Reaccessing the radial artery after occlusion is feasible for repeat neuroendovascular procedures.

Maladaptive Personality Traits and Psychopathological Symptoms in Individuals with the First Suicidal Attempt and with Chronic Suicidal Behavior

The paper compares the severity of maladaptive personality traits and psychopathological symptoms in patients with primary and repeated suicide attempts. The study involved patients of the somatopsychiatric department of the Sklifosovsky Research Institute of Emergency Care (N=61), who committed the first suicide attempt (n=31) or a repeated attempt (n=30). The results of the study did not reveal differences between the two groups in the severity of symptoms of social anxiety, depression and trait anxiety. However, indicators of such maladaptive personality traits as perfectionism and hypersensitive narcissism were significantly higher in the group of patients with a repeated suicide attempt. This group also manifested higher rates of the severity of borderline personality disorder traits and significant correlations between measures of psychopathology and maladaptive personality traits listed above. Conclusion: timely diagnostics of maladaptive traits and psychotherapy targeting socially prescribed perfectionism, hypersensitive narcissism, and borderline personality features after the first suicide attempt is necessary to prevent repeated ones.

Abstract 447: Longitudinal Improvement in CPR Quality Following RQI Implementation in a Pediatric Emergency Department

Introduction and Objective: The optimal retraining interval in CPR for healthcare providers is unknown. The Resuscitation Quality Improvement Program (RQI ® ) is a competency based, low-dose high-frequency quality improvement solution CPR psychomotor skills. We sought to describe the longitudinal change in skill performance during simulated CPR over a one year period following the implementation of RQI in a tertiary pediatric ED. Methods: Observational study in a single pediatric ED. All healthcare providers involved in resuscitative care in the ED were enrolled in RQI in October 2017. Once per 3-month period, each provider completed a feedback-guided skills session for 4 basic BLS skills (Infant compressions, infant ventilation, adult compressions, adult ventilation). A weighted scoring algorithm (range 0-100%) was used to score each subject’s performance. In the event of a score of less than 75%, repeated attempt(s) were required until a passing score was achieved. Q4 2017 median overall scores and first daily scores were compared to Q3 2018 median overall scores and first daily scores using a Wilcoxon Signed-Rank Test. Results: 159 providers completed all four quarterly training sessions in the 12-month study period. Median scores stratified by quarter and difference scores between the first and last quarter for each task are shown in Table 1. Overall scores and first daily scores for all four psychomotor CPR skills improved significantly for all tasks between Q4 2017 and Q3 2018. Conclusions: Pediatric ED providers enrolled in RQI showed improved CPR skill performance over a one year period. Future research should link RQI training and skill performance with CPR performance during actual patient care.

Maternal characteristics in childhood and smoking at age of 15: Findings from the Czech Republic

Objective Maternal employment has been shown to influence child’s health, cognitive and behavioural outcomes. There is only a limited number of studies in Central Europe investigating the impact of parental employment on the uptake of smoking in children. The aim of this work is to look at the influence of maternal employment over the whole period of childhood of their children, and other maternal social and behavioural characteristics on the uptake of smoking among children aged 15 in the Czech part of European Longitudinal Study of Pregnancy and Childhood (ELSPAC). Methods There were 971 individuals with complete data on smoking behaviour at age of 15, pattern of maternal employment between child ages 3 and 15, and other covariates including gender, maternal age, maternal education and marital status, household income, and maternal smoking. Logistic regression was used to analyse the association between maternal employment and smoking in their children. Results 37% of adolescents aged 15 years reported trying cigarette more than once. Preliminary results suggest that those whose mothers were in paid work were more likely to be smoking at age 15. When stratified by maternal education, the association between maternal employment and smoking was particularly strong among university educated mothers. Those whose mothers were never employed were 4-times more likely to smoke than those whose mothers were continuously employed between ages 3 and 15. The association between maternal employment and smoking was weaker in other strata of maternal education. Conclusions Although maternal employment might have only a limited role in development of smoking behaviour of young adolescents, the association between maternal employment during childhood and young adolescents’ smoking does exist and is particularly strong among those with university educated mothers. Key messages More than one third of Czech adolescents self-reported repeated attempt to smoke cigarettes or cigars or pipe at the beginning of new Millennium. Data suggest that adolescents whose mothers had not been employed were more likely to smoke than those of employed mothers.

Evaluation of the influence of clinical risk factors on the performance of extracorporal fertilization programs

Purpose of the study. To assess the influence of main clinical risk factors on the effectiveness of the in vitro fertilization (IVF) program.Materials and methods. The study included 3,969 IVF programs conducted in the “Medica” clinic of the “Mother and Child” group of companies in Novokuznetsk for 2010–2015. The inclusion criterion was the availability of information on the results of the procedure conducted.Results.The structure of the considered risk factors was identified, their key features were identified: the majority of women who underwent IVF procedure were under the age of 34, inclusive, more than half of all procedures were performed at the first attempt. The main causes of female infertility were: tubal factor, including those associated with chronic endometritis, polycystic ovary syndrome, external genital endometriosis and adenomyosis. In a number of cases, as a concomitant gynecological disease, uterine fibroids have been extirpated, which is not the main cause of infertility, but the presence of which can influence the effectiveness of IVF programs. Statistically significantly more often, fibroids were found in adenomyosis and tubal factors associated with chronic endometritis. A quantitative assessment of the degree of influence of the considered risk factors on the effectiveness of IVF programs was considered, and the influence of both individual factors and their combination was considered.Conclusion.The main factors statistically significantly increasing the risk of a negative outcome of the program are: the age of a woman over 30; repeated attempt at the age of up to 30 years inclusive (in comparison with the first attempt); tubular factor associated with chronic endometritis; presence of uterine fibroids in the tubular factor associated with chronic endometritis; The presence of fibroids in the tubular factor, complicated by adenomyosis.

Stealing the Scene: Crime as Confession in Robert Bresson’s Pickpocket

Noting the difficulty of interpreting Bresson’s use of Dostoevskii’s Crime and Punishment in The Pickpocket as an adaptation per se, this chapter argues that the director takes part in the generic tradition of confession. Pickpocketing becomes not just a crime but also, through Bresson’s disruption of the psychological cause and effect that the viewer expects, a repeated attempt at confession. Because of Bresson’s hero’s inability to explain the motivation for his crime, he resembles not only Dostoevskii’s hero Raskolnikov, but also Meursault of Camus’s The Stranger. By creating these gaps, Bresson forces viewers to negotiate the borders not only between genres but between disconnected acts.
