Predictors of atrial fibrillation recurrence after surgical ablation of long-standing persistent AF with concomitant coronary artery bypass grafting

Background A long-standing persistent form of atrial fibrillation (AF) in anamnesis, requiring surgical ablation together with coronary artery bypass surgery (CABG), significantly increases the risk of reccurence in the postoperative period. Before operation should consider the predictors of AF for long-term preservation of rhythm after surgery. Purpose To evaluate the predictors of AF recurrence on 3rd day and at discharge in patients after CABG with concomitant surgical ablation of long-standing persistent AF. Methods A prospective randomized single-center analysis was performed on patients with long-standing persistent AF, undergoing CABG with concomitant left atrial ablation (LAA) or biatrial ablation (BA) between 2016 and 2019. 116 patients were randomized into two groups: 58 in LAA+CABG, 58 in BA+CABG. The median age of the patients was 65 (IQR, 61 to 67.75) years in gr. BA and 62 (IQR, 58 to 66) in gr. LAA (Mann-Whitney U-test, p=0.050), 83% of men were in gr. BA (Fisher test, p>0.999). Predictors of AF development on day 3 were identified using multivariable logistic regression from the following baseline characteristics: myocardial infarction in anamnesis, time of artificial circulation, time of application of radiofrequency energy, the size of the left and right atrium, funcrional class of cardiac angina and heart failure, gender, age, acute cerebrovascular accident (CVA), additional intervention on the heart (operations for aortic aneurysm, mitral, aortic and tricuspid valves replacement), concomitant cardiovascular, respiratory, digestive and urogenital diseases. Results Using a multivariate model of logistic regression, the following significant predictors of arrhythmias on the 3rd day in gr. BA were included: additional intervention on the heart valves (OR 63.13, p=0.001); an increase in the functional class (FC) of chronic heart failure (CHF) NYHA by 1 (OR 40.06, p=0.018); a history of CVA (OR 9.13, p=0.026). The following significant predictors of AF reccurence on the 3rd day in gr.LAA were identified: an increase in the long axis of the right atrium by 1 cm (OR 3.05, p=0.006); an increase of the FC of cardiac angina by 1 (OR 7.11, p=0.011); in women (OR 7.14, p=0.017). In BA significant predictors of AF reccurence at discharge were: an increase in the long axis of the left atrium by 1 cm (OR4.86, p=0.015); reccurence of AF on the 3rd day (OR 17.45, p=0.005); 1 year increase in age (OR 1.24, p=0.023); the presence of diabetes (OR 47.67, p=0.002). In gr. LAA the predictors at discharge were: reccurence of AF on 3rd day (OR 38.35, p=0.001); a history of CVA increases the chances of arrhythmia (OR 210.83, p=0.032). Conclusion Number of clinical and functional characteristics of a patient may be predictors of AF. We examined the predictors of reccurence of AF after surgical ablation of long-standing persistent AF with concomitant CABG. Taking them into account when choosing the optimal strategy of treatment is important. FUNDunding Acknowledgement Type of funding sources: None.

Outcomes after endovascular embolization for the treatment of nasal and oropharyngeal hemorrhage: safety, efficacy, and rebleeding

Background Intractable nasal and oropharyngeal hemorrhage may be treated with endovascular embolization, but limited data are available. We sought to evaluate the efficacy, safety, and factors associated with rebleeding. Methods A retrospective analysis of consecutive embolizations for nasal and oropharyngeal hemorrhage over a 10-year period at a single institution was performed. Outcomes included procedural success (defined as cessation of hemorrhage in the immediate postoperative period), rebleeding requiring an additional intervention, and procedural complications. Results A total of 47 embolizations on 39 patients were included. The mean age was 60 years (standard deviation 16.1), 23.1% of patients were women, and 21 (53.8%) patients had a previously diagnosed head/neck malignancy. Bleeding sites were the nose in 20 patients and oropharynx in 21 (two patients presented with both nasal and oral bleeding). Immediate procedural success was achieved in 45 (95.7%) embolizations. Rebleeding requiring an additional intervention occurred after 11 (23.4%) embolizations at a median of one day after the procedure. In the multivariate analysis, preoperative hypotension (odds ratio 4.78, 95% confidence interval 1.04–24.61) and the use of coils (odds ratio 6.09, 95% confidence interval 1.24–46.69) were associated with rebleeding requiring repeat intervention. Complications included two watershed strokes that were anticipated due to occlusion of the internal carotid artery. Conclusions In our experience endovascular embolization was a safe and effective treatment option for stopping oral and nasal hemorrhage. However, rebleeding was present after 23.4% of treatments and was associated with preoperative hypotension and the use of coils. Further study in a large multi-institutional cohort is warranted.

High-Resolution Esophageal Manometry in the Inpatient Setting: A Tertiary Referral Center Experience

High-resolution esophageal manometry (HRM) is frequently used in the outpatient setting, but its role in the inpatient setting is unknown. We conducted a retrospective study of patients who underwent inpatient or outpatient HRM. Few differences were noted between groups and 28% of inpatients had an additional intervention. Tolerance of oral diet and diabetes were associated with a lower likelihood of additional intervention. Ultimately, the inpatient HRM group had unique characteristics and few subsequent interventions.

Defining turn taking in intervention for young children with autism: A review of the literature

Turn taking is a form of preverbal, dyadic, reciprocal communication that may support key areas of development, such as language and joint attention, and may serve different functions depending on each communicative partner’s intent. As such, it has been incorporated in interventions targeting various outcomes in young children with autism. However, there is inconsistency in how researchers define turn taking and explorations on how turn taking is defined across these interventions have not yet been reported in the current literature. Therefore, the purpose of this review was to investigate how turn taking is operationally defined based on communicative intent in the current literature on interventions for young children with autism and to explore additional intervention content to provide fuller context to how turn taking has been promoted. A search was conducted across databases to identify intervention studies for young children with autism that incorporated an embedded turn-taking component. Peer-reviewed articles were then coded based on turn-taking communicative intent, and additional intervention content was categorized. Findings across 14 studies indicate variability among turn-taking definitions both in communicative function and form. The results also reveal that turn taking has been promoted through different intervention approaches that incorporate diverse agents, settings, and methodology. Researchers and practitioners should consider specificity and clarity when defining turn taking to most optimally meet the developmental needs of young children with autism in future interventions.

A Laboratory Procedure to Facilitate Color Conscious Racial Socialization Methods Among White Parents in the U.S.

For years, White U.S. parents have strived to raise colorblind children, yet mounting evidence indicates that color conscious racial socialization is needed to cultivate an anti-racist orientation. The current work evaluates a new semi-structured laboratory procedure to facilitate color conscious racial socialization in 87 White parent-child (8-12-year-olds) dyads. Contrasting with prior research, qualitative findings revealed that most parents used racial labels and color conscious racial socialization methods. However, a subset of parents pushed back against the color conscious guidance, encouraging racial ignorance or external attributions for racist behaviors. This work highlights promising evidence of a means for facilitating color conscious socialization in White families, and additional intervention targets for future efforts to foster anti- racism in White families.

Comparison of surgical versus medical termination of pregnancy between 13-20 weeks of gestation in Ethiopia: A quasi-experimental study

Background Dilation and evacuation is a method of second trimester pregnancy termination introduced recently in Ethiopia. However, little is known about the safety and effectiveness of this method in an Ethiopian setting. Therefore, the study is intended to determine the safety and effectiveness of dilation and evacuation for surgical abortion as compared to medical abortion between 13–20 weeks’ gestational age. Methods This is a quasi-experimental study of women receiving second trimester termination of pregnancy between 13–20 weeks. Patients were allocated to either medical or surgical abortion based on their preference. A structured questionnaire was used to collect demographic information and clinical data upon admission. Procedure related information was collected after the procedure was completed and before the patient was discharged. Additionally, women were contacted 2 weeks after the procedure to evaluate for post-procedural complications. The primary outcome of the study was a composite complication rate. Data were collected using Open Data Kit and then analyzed using Stata version 14.2. Univariate analyses were performed using means (standard deviation), or medians (interquartile range) when the distribution was not normal. Multiple logistic regression was also performed to control for confounders. Results Two hundred nineteen women chose medical abortion and 60 chose surgical abortion. The composite complication rate is not significantly different among medical and surgical abortion patients (15% versus 10%; p = 0.52). Nine patients (4.1%) in the medical arm required additional intervention to complete the abortion, while none of the surgical abortion patients required additional intervention. Median (IQR) hospital stay was significantly longer in the medical group at 24 (12–24) hours versus 6(4–6) hours in the surgical group p<0.001. Conclusion From the current study findings, we concluded that there is no difference in safety between surgical and medical methods of abortion. This study demonstrates that surgical abortion can be used as a safe and effective alternative to medical abortion and should be offered equivalently with medical abortion, per the patient’s preference.

Additional intervention evidence on the relationship between public service motivation and ethical behavior

The nascent scholarship on public service motivation (PSM) and ethics exhibits mixed findings. This research article aims to describe and relate the current landscape of findings in this arena and to conduct an experiment that addresses design weaknesses that may explain some past null findings. Using a national sample of college-age respondents, we found that although self-reported PSM was positively correlated with ethical intentions, prosocial priming did not increase ethical intentions or behavior. We contextualize these findings in terms of previous studies, to inform our understanding of the efficacy of prosocial interventions. While our research suggests that self-reported PSM can predict, if not influence, ethical intention, we are unable to make conclusions about PSM’s effects on ethical behavior. Second, similar to past studies, we are not able to confirm specific mechanisms or interventions that might be used to increase ethical behavior or intentions.

Stereotactic radiosurgery as the first-line treatment for intracanalicular vestibular schwannomas

OBJECTIVEThis report evaluates the outcomes of stereotactic radiosurgery (SRS) as the first-line treatment of intracanalicular vestibular schwannomas (VSs).METHODSBetween 1987 and 2017, the authors identified 209 patients who underwent SRS as the primary intervention for a unilateral intracanalicular VS. The median patient age was 54 years (range 22–85 years); 94 patients were male and 115 were female. Three patients had facial neuropathy at the time of SRS. One hundred fifty-five patients (74%) had serviceable hearing (Gardner-Robertson [GR] grades I and II) at the time of SRS. The median tumor volume was 0.17 cm3 (range 0.015–0.63 cm3). The median margin dose was 12.5 Gy (range 11.0–25.0 Gy). The median maximum dose was 24.0 Gy (range 15.7–50.0 Gy).RESULTSThe progression-free survival rates of all patients with intracanalicular VS were 97.5% at 3 years, 95.6% at 5 years, and 92.1% at 10 years. The rates of freedom from the need for any additional intervention were 99.4% at 3 years, 98.3% at 5 years, and 98.3% at 10 years. The serviceable hearing preservation rates in GR grade I and II patients at the time of SRS were 76.6% at 3 years, 63.5% at 5 years, and 27.3% at 10 years. In univariate analysis, younger age (< 55 years, p = 0.011), better initial hearing (GR grade I, p < 0.001), and smaller tumor volumes (< 0.14 cm3, p = 0.016) were significantly associated with improved hearing preservation. In multivariate analysis, better hearing (GR grade I, p = 0.001, HR 2.869, 95% CI 1.569–5.248) and smaller tumor volumes (< 0.14 cm3, p = 0.033, HR 2.071, 95% CI 1.059–4.047) at the time of SRS were significantly associated with improved hearing preservation. The hearing preservation rates of patients with GR grade I VS were 88.1% at 3 years, 77.9% at 5 years, and 38.1% at 10 years. The hearing preservation rates of patients with VSs smaller than 0.14 cm3 were 85.5% at 3 years, 77.7% at 5 years, and 42.6% at 10 years. Facial neuropathy developed in 1.4% from 6 to 156 months after SRS.CONCLUSIONSSRS provided sustained tumor control in more than 90% of patients with intracanalicular VS at 10 years and freedom from the need for additional intervention in more than 98% at 10 years. Patients with initially better hearing and smaller VSs had enhanced serviceable hearing preservation during an observation interval up to 10 years after SRS.
