Pre-attentive and Attentive Auditory Event-related Potentials in Children With Attention-Deficit Hyperactivity Disorder and Autism.

Abnormalities in auditory processing are believed to play a major role in autism and attention-deficit hyperactivity disorder (ADHD). Both conditions often co-occur in children, causing difficulties in deciding the most promising intervention. Event-related potentials (ERPs) have been investigated and are showing promise to act as potential biomarkers for both conditions. This study investigated mismatch negativity (MMN) using a passive listening task and P3b in an active auditory go/no-go discrimination task. Recordings were available from 103 children (24 females): 35 with ADHD, 27 autistic, 15 autistic children with co-occurring ADHD, and 26 neurotypical (NT) children. The age range considered was between 4 and 17 years, but varied between groups. The results revealed increases in the MMN and P3b amplitudes with age. Older children with ADHD exhibited smaller P3b amplitudes, while younger autistic children showed reduced MMN amplitudes in response to phoneme changes compared to their NT counterparts. Notably, children diagnosed with autism and ADHD did not follow this pattern; instead, they exhibited more similarities to NT children. The reduced amplitudes of phonetically elicited MMN in children with autism and reduced P3b in children with ADHD suggest that the two respective ERPs can act as potential biomarkers for each condition. However, optimisation and standardisation of the testing protocol, as well as longitudinal studies are required in order to translate these findings into clinical practice.

Impact of superior semicircular canal dehiscence on cochlear implant audiologic outcomes.

PURPOSE: Determine whether adult cochlear implant users with radiographic superior semicircular canal dehiscence experience clinically significant differences in audiological outcomes when compared to cochlear implant users with normal temporal bone anatomy. MATERIALS AND METHODS: Retrospective, single institution review. Adult, post-lingual deaf patients implanted between 2010 and 2020. Inclusion criteria included age 18 years or older, available preoperative computed tomography imaging, and preoperative and postoperative AzBio audiological data for at least 6 months of cochlear implant use. Preoperative and postoperative AzBio Sentence Test scores were compared between patients with normal temporal bone anatomy and those with radiographic superior semicircular canal dehiscence or near dehiscence. RESULTS: 110 patients met inclusion criteria. Mean AzBio score for normal temporal bone anatomy group improved from 35.2 % (SD 28.2) preoperatively to 70.3 % (SD 25.7) postoperatively, an improvement of 35.1 % (SD 28.6). Mean AzBio score for near dehiscent temporal bone anatomy group improved from 26.6 % (SD 28.9) preoperatively to 64.5 % (SD 30.6) postoperatively, an improvement of 37.9 % (SD 27.9). Mean AzBio score for dehiscent temporal bone anatomy group improved from 26.3 % (SD 20.4) preoperatively to 65.1 % (SD 27.6) postoperatively, an improvement of 38.7 % (SD 26.9). Utilizing the one-way analysis of variance test, there was no significant difference in audiologic outcomes between the three groups. CONCLUSIONS: Patients with complete or near complete radiographic superior canal dehiscence at the time of cochlear implantation achieve similar improvements in speech perception scores compared to normal anatomy adult cochlear implant users.

The impact of race/ethnicity on pancreaticoduodenectomy outcomes for pancreatic cancer.

PURPOSE: To investigate the impact of race/ethnicity on surgical outcomes following pancreaticoduodenectomy for pancreatic cancer. METHODS: A retrospective review of patients undergoing pancreaticoduodenectomy for adenocarcinoma in the National Surgical Quality Improvement Program (NSQIP) database from 2014 to 2019. Patient and tumor characteristics and 30-day postoperative outcomes were compared. Multivariable logistic and linear regression models were conducted to investigate the relationship between race/ethnicity and surgical outcomes. RESULTS: Six thousand five hundred and sixty-two patients were included (84.5% White, 7.9% Black, 3% Hispanic, 4.6% Asian). Larger proportions of Blacks had preoperative American Society of Anesthesiologists class 3 or 4. There were no significant differences in tumor characteristics or operative techniques. A smaller proportion of Asians and Hispanics received neoadjuvant chemotherapy and/or radiation than Blacks and Whites. Relative to White, the Black race was independently associated with postoperative sepsis and reoperation. Both Black and Hispanic race/ethnicity were associated with prolonged intubation and delayed gastric emptying, and minorities races/ethnicities were associated with longer length of hospital stay. Relative to White, Hispanic, and Asian race/ethnicity were independently associated with a lower likelihood of neoadjuvant therapy (NAT) receipt. CONCLUSION: In ACS-NSQIP participating hospitals, non-White race/ethnicity was independently associated with adverse outcomes after pancreatic cancer resection. A possible disparity in NAT receipt may exist in Asian and Hispanic patients undergoing surgical resection.

Effect of Portable, In-Hospital Extracorporeal Membrane Oxygenation on Clinical Outcomes.

The time between onset of cardiogenic shock and initiation of mechanical circulatory support is inversely related to patient survival as delays in transporting patients to the operating room (OR) for venoarterial extracorporeal membrane oxygenation (VA ECMO) could prove fatal. A primed and portable VA ECMO system may allow faster initiation of ECMO in various hospital locations and subsequently improve outcomes for patients in cardiogenic shock. We reviewed our institutional experience with VA ECMO based on two time periods: beginning of our VA ECMO program and from initiation of our primed and portable in-hospital ECMO system. The primary endpoint was patient survival to discharge. A total of 137 patients were placed on VA ECMO during the study period; n = 66 (48%) before and n = 71 (52%) after program initiation. In the second era, the proportion of OR ECMO initiation decreased significantly (from 92% to 49%, p < 0.01) as more patients received ECMO in other hospital units, including the emergency department (p < 0.01) and during cardiac arrest (12% vs. 38%, p < 0.01). Survival to hospital discharge was equivalent between the two groups (30% vs. 42%, p = 0.1) despite more patients being placed on ECMO during ongoing cardiac arrest. Finally, we observed increased clinical volume since initiation of the in-hospital, portable ECMO system. Developing an in-hospital, primed and portable VA ECMO program resulted in increased clinical volume with equivalent patient survival despite a sicker cohort of patients. We conclude that more rapid deployment of VA ECMO may extend the treatment eligibility to more patients and improve patient outcomes.

Trends of utilization and perioperative outcomes of robotic and video-assisted thoracoscopic surgery in patients with lung cancer undergoing minimally invasive resection in the United States.

Objective: The objective of this study was to evaluate utilization and perioperative outcomes of video-assisted thoracoscopic surgery (VATS) or robotic-assisted thoracoscopic surgery (RATS) for lung cancer in the United States using a nationally representative database. Methods: Hospital admissions for lobectomy or sublobar resection (segmentectomy or wedge resection) using VATS or RATS in patients with nonmetastatic lung cancer from October 2015 through December 2018 in the National Inpatient Sample were studied. Patient and hospital characteristics, perioperative complications and mortality, length of stay (LOS), and total hospital cost were compared. Logistic regression was used to assess whether the surgical approach was independently associated with adverse outcomes. Results: There were 83,105 patients who had VATS (n = 65,375) or RATS (n = 17,710) for lobectomy (72.7% VATS) or sublobar resection (84.2% VATS). Utilization of RATS for lobectomy and sublobar resection increased from 19.2% to 34% and 7.3% to 22%, respectively. Mortality, LOS, and conversion rates were comparable. The cost was higher for RATS (P <.01). Multivariate analyses showed comparable RATS and VATS complications with no independent association between the minimally invasive surgery approach used and adverse surgical outcomes, except for a decreased risk of pneumonia with RATS, relative to VATS sublobar resection (P <.01). Thoracic complication rates and LOS decreased after RATS lobectomy in 2018, compared with previous years (P <.005). Conclusions: The utilization of robotic-assisted lung resection for cancer has increased in the United States between 2015 and 2018 for sublobar resection and lobectomy. In adjusted regression analysis, compared with VATS, patients who underwent RATS had similar complication rates and LOS. The robotic approach was associated with increased total hospital cost. LOS and thoracic complication rates trended down after RATS lobectomy.

The Emergency Surgery Score accurately predicts the need for postdischarge respiratory and renal support after emergent laparotomies: A prospective EAST multicenter study.

BACKGROUND: The Emergency Surgery Score (ESS) was recently validated as an accurate mortality risk calculator for emergency general surgery. We sought to prospectively evaluate whether ESS can predict the need for respiratory and/or renal support (RRS) at discharge after emergent laparotomies (EL). METHODS: This is a post hoc analysis of a 19-center prospective observational study. Between April 2018 and June 2019, all adult patients undergoing EL were enrolled. Preoperative, intraoperative, and postoperative variables were systematically collected. In this analysis, patients were excluded if they died during the index hospitalization, were discharged to hospice, or transferred to other hospitals. A composite variable, the need for RRS, was defined as the need for one or more of the following at hospital discharge: tracheostomy, ventilator dependence, or dialysis. Emergency Surgery Score was calculated for all patients, and the correlation between ESS and RRS was examined using the c-statistics method. RESULTS: From a total of 1,649 patients, 1,347 were included. Median age was 60 years, 49.4% were men, and 70.9% were White. The most common diagnoses were hollow viscus organ perforation (28.1%) and small bowel obstruction (24.5%); 87 patients (6.5%) had a need for RRS (4.7% tracheostomy, 2.7% dialysis, and 1.3% ventilator dependence). Emergency Surgery Score predicted the need for RRS in a stepwise fashion; for example, 0.7%, 26.2%, and 85.7% of patients required RRS at an ESS of 2, 12, and 16, respectively. The c-statistics for the need for RRS, the need for tracheostomy, ventilator dependence, or dialysis at discharge were 0.84, 0.82, 0.79, and 0.88, respectively. CONCLUSION: Emergency Surgery Score accurately predicts the need for RRS at discharge in EL patients and could be used for preoperative patient counseling and for quality of care benchmarking. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.

The emergency surgery score (ESS) and outcomes in elderly patients undergoing emergency laparotomy: A post-hoc analysis of an EAST multicenter study.

INTRODUCTION: We sought to evaluate whether the Emergency Surgery Score (ESS) can accurately predict outcomes in elderly patients undergoing emergent laparotomy (EL). METHODS: This is a post-hoc analysis of an EAST multicenter study. Between April 2018 and June 2019, all adult patients undergoing EL in 19 participating hospitals were prospectively enrolled, and ESS was calculated for each patient. Using the c-statistic, the correlation between ESS and mortality, morbidity, and need for ICU admission was assessed in three patient age cohorts (65-74, 75-84, ≥85 years old). RESULTS: 715 patients were included, of which 52% were 65-74, 34% were 75-84, and 14% were ≥85 years old; 51% were female, and 77% were white. ESS strongly correlated with postoperative mortality (c-statistic:0.81). Mortality gradually increased from 0% to 20%-60% at ESS of 2, 10 and 16 points, respectively. ESS predicted mortality, morbidity, and need for ICU best in patients 65-74 years old (c-statistic:0.81, 0.75, 0.83 respectively), but its performance significantly decreased in patients ≥85 years (c-statistic:0.72, 0.64, 0.67 respectively). CONCLUSION: ESS is an accurate predictor of outcome in the elderly EL patient 65-85 years old, but its performance decreases for patients ≥85. Consideration should be given to modify ESS to better predict outcomes in the very elderly patient population.

E-technology social support programs for autistic children: Can they work?

Autism is a neurodevelopmental condition with associated difficulties that present differently across individuals. One such difficulty is recognizing basic and complex facial expressions. Research has previously found that there are many evidence-based support programs available for building non-verbal communication skills. These programs are frequently administered with a therapist or in a group setting, making them inflexible in nature. Programs hosted on e-technology are becoming increasingly popular, with many parents supportive of them. Applications (apps) that are hosted on technology such as iPads or mobile phones allow users to engage in building skills in real-time social settings and own what they are learning. These technologies are frequently used by autistic children, with apps typically focusing on identifying facial features. Yet at this current time, there are mixed reviews of how to design such programs and what their theoretical backing is, with many studies using a mix of observation and psychological assessments as outcome measures. Eye-tracking and electroencephalography are established methodologies that measure neural processing and gaze behaviors while viewing faces. To better support the field moving forward, objective measures such as these are a way to measure outcomes of apps that are designed for helping children on the spectrum build skills in understanding facial expressions.

Use of an enterocolitis triage and treatment protocol in children with Hirschsprung disease reduces hospital admissions.

BACKGROUND: While a consensus for the definition of Hirschsprung associated enterocolitis (HAEC) is lacking, the mainstay of treatment includes rectal irrigations with or without antibiotics. This treatment is often effective when initiated as an outpatient. Our institution implemented a triage algorithm in an effort to standardize care thus providing more timely treatment and preventing unnecessary hospital admissions. We sought to review our short-term experience. METHODS: A retrospective review was performed of all Hirschsprung (HD) patients <6 years old over two distinct time periods from May 2016-2017 (pre-protocol, group A) and June 2017-2018 (post-protocol, group B). Patients with a colostomy were excluded. Primary end point was hospital admission. Presenting symptoms were categorized as moderate or severe, with patient triage based on number and quality of symptoms. RESULTS: Eighty-seven total patients were included. Rectosigmoid transition zone was most common (75%) and 20% of patients had trisomy 21. HAEC occurred in 22% of patients in the preprotocol group (group A, n = 78, 27 episodes) and 20% of patients in the post-protocol group (group B, n = 87, 32 episodes). In group A, 78% of episodes required an unplanned visit and 74% resulted in admission. In group B, 81% of episodes required an unplanned visit and 50% resulted in admission (33% reduction in hospital admission, p = 0.06). Irrigations only, without antibiotics, were used in 30% of episodes in group A versus 41% in group B. Of patients who initially contacted the office by phone (group A = 7 episodes, group B = 6 episodes), outpatient management was successful in 43% versus 100% respectively (p = 0.07). No patient experienced increased morbidity in group B. DISCUSSION: Implementation of a HAEC treatment algorithm shows promise in improving the management and resource utilization of this complex patient population. It is anticipated that continued education of caregivers and the treatment team will result in a greater effect. A multi-institutional implementation of this algorithm is needed to characterize risk factors associated with failure of outpatient management. LEVEL OF EVIDENCE: III, Treatment Study.

Prospective validation of the Emergency Surgery Score in emergency general surgery: An Eastern Association for the Surgery of Trauma multicenter study.

BACKGROUND: The Emergency Surgery Score (ESS) was recently developed and retrospectively validated as an accurate mortality risk calculator for emergency general surgery. We sought to prospectively validate ESS, specifically in the high-risk nontrauma emergency laparotomy (EL) patient. METHODS: This is an Eastern Association for the Surgery of Trauma multicenter prospective observational study. Between April 2018 and June 2019, 19 centers enrolled all adults (aged >18 years) undergoing EL. Preoperative, intraoperative, and postoperative variables were prospectively and systematically collected. Emergency Surgery Score was calculated for each patient and validated using c-statistic methodology by correlating it with three postoperative outcomes: (1) 30-day mortality, (2) 30-day complications (e.g., respiratory/renal failure, infection), and (3) postoperative intensive care unit (ICU) admission. RESULTS: A total of 1,649 patients were included. The mean age was 60.5 years, 50.3% were female, and 71.4% were white. The mean ESS was 6, and the most common indication for EL was hollow viscus perforation. The 30-day mortality and complication rates were 14.8% and 53.3%; 57.0% of patients required ICU admission. Emergency Surgery Score gradually and accurately predicted 30-day mortality; 3.5%, 50.0%, and 85.7% of patients with ESS of 3, 12, and 17 died after surgery, respectively, with a c-statistic of 0.84. Similarly, ESS gradually and accurately predicted complications; 21.0%, 57.1%, and 88.9% of patients with ESS of 1, 6, and 13 developed postoperative complications, with a c-statistic of 0.74. Emergency Surgery Score also accurately predicted which patients required intensive care unit admission (c-statistic, 0.80). CONCLUSION: This is the first prospective multicenter study to validate ESS as an accurate predictor of outcome in the EL patient. Emergency Surgery Score can prove useful for (1) perioperative patient and family counseling, (2) triaging patients to the intensive care unit, and (3) benchmarking the quality of emergency general surgery care.

The effect of multidisciplinary colorectal center development on short-term hospital readmissions for patients with anorectal malformations or Hirschsprung disease.

INTRODUCTION: Hospital readmissions have become a quality metric for both hospital systems and individual surgeons. The medical literature is replete with studies describing readmission rates and factors contributing to readmissions following surgical procedures. Relatively little, however, has been done to define potential solutions to these problems. Over the past decade there has been a movement toward the development of multidisciplinary colorectal centers at high volume children's hospitals. We hypothesized that the development of a colorectal center at our children's hospital decreased readmissions in our colorectal surgery population. MATERIALS AND METHODS: A retrospective review was performed including all patients with the diagnosis of anorectal malformation (ARM) or Hirschsprung disease (HD) at our institution between the years of 2005-2017. Patient level outcomes were compared between the cohort treated prior to (2005-2010) and the cohort treated after the development of the colorectal center (2012-2017). RESULTS: A total of 354 patients were identified. One hundred seventy-eight patients (113 ARM, 65 HD) were treated prior to and 176 patients (110 ARM, 66 HD) were treated after the development of the colorectal center. Forty-five (25.3%) patients underwent neonatal repair prior to development of the center compared to 15 (8.5%) after. 111 (62.4%) patients underwent colostomy prior to the colorectal center comparted to 95 (54%) after. The rate of readmission within 120 days of discharge in the early group was 63% compared to 52% in those managed in the multidisciplinary colorectal center (p = 0.04). Conversely, the rate of emergency room visits increased from 8.4% to 27.3% (p = 0.01). The decrease in readmission rates was more pronounced in the ARM group, while the HD cohort had similar readmission rates before and after the establishment of the center. Multivariate logistic regression revealed an odds ratio of 0.59 (95% CI 0.37-0.92) for readmission following the development of the multidisciplinary colorectal center. DISCUSSION: The development of a multidisciplinary colorectal center at our institution was associated with decreased hospital readmissions, but an increase in emergency department resource utilization. These findings suggest improved efficiency in patient care with the implementation of a multispecialty, patient centered approach while also identifying areas of focus for future quality improvement initiatives. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Rapid face orienting in infants and school-age children with and without autism: Exploring measurement invariance in eye-tracking.

Questions concerning the ontogenetic stability of autism have recently received increased attention as long-term longitudinal studies have appeared in the literature. Most experimental measures are designed for specific ages and functioning levels, yet developing experimental tasks appropriate for a wide range of ages and functioning levels is critical for future long-term longitudinal studies, and treatment studies implemented at different ages. Accordingly, we designed an eye-tracking task to measure preferential orienting to facial features and implemented it with groups of participants with varying levels of functioning: infants, and school-age children with and without autism. All groups fixated eyes first, revealing an early and stable orienting bias. This indicates common bias towards the eyes across participants regardless of age or diagnosis. We also demonstrate that this eye-tracking task can be used with diverse populations who range in age and cognitive functioning. Our developmental approach has conceptual implications for future work focused on task development and particularly new experimental measures that offer measurement equivalence across broad age ranges, intellectual functioning and verbal abilities.

Early Successes in an Open Access, Provincially Funded Hepatitis C Treatment Program in Prince Edward Island.

INTRODUCTION: The availability of curative hepatitis C therapies has created an opportunity to improve treatment delivery and access. Local providers, government, industry, and community groups in Prince Edward Island developed an innovative province-wide care model. Our goal was to describe the first year of program implementation. MATERIAL AND METHODS: Using a communitybased prospective observational study design, all chronic hepatitis C referrals received from April 2015 to April 2016 were recorded in a database. Primary analysis assessed the time from referral to assessment/treatment, as well as the number of referrals, assessments, and treatment initiations. Secondary objectives included: (1) treatment effectiveness using intention-to-treat analysis; and (2) patient treatment experience assessed using demographics, adverse events, and medication adherence. RESULTS: During the study period 242 referrals were received, 123 patients were seen for intake assessments, and 93 initiated direct-acting antiviral therapy based on medical need. This is compared to 4 treatment initiations in the previous 2 years. The median time from assessment to treatment initiation was 3 weeks. Eighty-two of 84 (97.6%, 95% CI 91.7 - 99.7%) patients for whom outcome data were available achieved sustained virologic response at 12 weeks post-treatment; 1 was lost to follow-up and 1 died from an unrelated event. In the voluntary registry, 39.7% of patients reported missed treatment doses. CONCLUSION: In conclusion, results from the first 12 months of this multi-phase hepatitis C elimination strategy demonstrate improved access to treatment, and high rates of safe engagement and cure for patients living with chronic hepatitis C genotype 1 infections.

Alexithymia and posttraumatic stress disorder following asthma attack.

This study examined the levels of posttraumatic stress disorder (PTSD) following asthma attack (post-asthma attack PTSD) and psychiatric co-morbidity among college students. It also investigated the association between these variables and alexithymia. One hundred and six college students participated in the study and completed an on-line survey comprising the Asthma Symptom Checklist, PTSD Checklist, General Health Questionnaire-28 and Toronto Alexithymia Scale. Ninety-one students without asthma and major illness formed the control group. 2 % met the diagnostic criteria for full-PTSD, while 42 and 56 % met the partial and no-PTSD criteria respectively. Compared with the control, the asthma group reported significantly more somatic problems, social dysfunction and depression and was five times more likely to have an elevated risk of developing a general psychiatric disorder. After adjusting age, marital status, asthma experience and symptoms, alexithymia did not predict PTSD, while difficulty identifying feelings predicted psychiatric co-morbidity. Mediational analyses showed that asthma symptoms partially mediated the link between difficulty identifying feelings and psychiatric co-morbidity. People can develop PTSD symptoms and other psychological difficulties following asthma attack. Alexithymia influenced general psychological difficulties independently of PTSD symptoms.

Unlocking reflective practice for nurses: innovations in working with master of nursing students in Hong Kong.

Being reflective is well established as an important conduit of practice development, a desirable tertiary graduate quality and a core competency of health professional membership. By assisting students to be more effective in their ability to reflect, they are better able to formulate strategies to manage issues experienced within a professional context, which ultimately assists them to be better service providers. However, some students are challenged by the practice of reflection and these challenges are even more notable for international students. This paper presents a teaching initiative that focused specifically on enhancing the capacity of an international cohort of nursing students, to engage in reflective practice. The initiative centered on an evaluation of a reflective practice core subject, which was taught in a Master of Nursing programme delivered in Hong Kong. A learning-centered framework was used to evaluate the subject and identify innovative strategies that would better assist international students to develop reflective practices. The outcomes of curriculum and teaching analysis and proposed changes and innovations in teaching practice to support international students are presented and discussed.

Posttraumatic stress disorder following asthma attack (post-asthma attack PTSD) and psychiatric co-morbidity: the impact of alexithymia and coping.

This study investigated the prevalence of post-asthma attack posttraumatic stress disorder (PTSD) and the severity of psychiatric co-morbidity among a group of college students and whether alexithymia and coping strategies would relate to health outcomes. This is a cross-sectional study in which 156 college students who had previously experienced asthma attack were recruited. They completed a demographic page, Asthma Symptom Checklist, PTSD Checklist, General Health Questionnaire-28, Toronto Alexithymia Scale and the COPE. They were also matched with 141 students without asthma. The results showed that 3% met the criteria for full-PTSD, 44% for partial and 53% for no-PTSD. There were no significant differences between the asthma and control groups in severity of psychiatric co-morbid symptoms. Path analyses showed that asthma severity was significantly correlated with PTSD and psychiatric co-morbidity. It was also correlated with alexithymia which was in turn associated with psychiatric co-morbidity but not PTSD. Coping strategies were not correlated with health outcomes. To conclude, people can develop PTSD symptoms and degrees of psychiatric co-morbid symptoms after suffering asthma attack. The severity of these symptoms relates to people's perceptions of asthma severity and alexithymia.

Should nurse academics engage in clinical practice?

The education of nurses has traditionally been conducted in the hospital based setting. This changed over the last few decades, with nursing education now being a tertiary based course in many countries. There were numerous reasons for this move, the main goal being to improve the educational experience of students and thus the competence of graduates. Nurse academics whose role is to educate students are faced with the challenge of ensuring their teaching reflects the contemporary nursing environment. One way of doing this is by actively engaging in clinical practice. However there are arguments for and against (as well as barriers to) them doing so and little empirical evidence to support either argument. Individually, nurse academics must make a decision about whether engaging in clinical practice is beneficial to their career and the students they teach.
