RESUMEN

This review describes our institution's standardized technique as well as potential pitfalls for therapeutic steroid injections in children with symptomatic neuromuscular hip dysplasia. Symptomatic, painful neuromuscular hip dysplasia can dramatically affect quality of life. Steroid injections are used to identify the source of perceived pain, temporarily treat pain while awaiting surgical intervention, or for therapeutic management for nonoperative hip joints.

RESUMEN

BACKGROUND: The modified Gartland classification is the most widely accepted grading method of supracondylar humeral fractures among orthopedic surgeons and is relevant to identifying fractures that may require surgery. OBJECTIVE: To assess the interobserver reliability of the modified Gartland classification among pediatric radiologists, pediatric orthopedic surgeons, and pediatric emergency medicine physicians. MATERIALS AND METHODS: Elbow radiographs for 100 children with supracondylar humeral fractures were retrospectively independently graded by two pediatric radiologists, two pediatric orthopedic surgeons, and two pediatric emergency medicine physicians using the modified Gartland classification. A third grader of the same subspecialty served as a tie-breaker as needed to reach consensus. Readers were blinded to one another and to the medical record. The modified Gartland grade documented in the medical record by the treating orthopedic provider was used as the reference standard. Interobserver agreement was assessed using kappa statistics. RESULTS: There was substantial interobserver agreement (kappa = 0.77 [95% CI, 0.69-0.85]) on consensus fracture grade between the three subspecialties. Similarly, when discriminating between Gartland type I and higher fracture grades, there was substantial interobserver agreement between specialties (kappa = 0.77 [95% CI, 0.66-0.89]). The grade assigned by pediatric radiologists differed from the reference standard on 15 occasions, pediatric emergency medicine differed on 19 occasions, and pediatric orthopedics differed on 9 occasions. CONCLUSION: The modified Gartland classification for supracondylar humeral fractures is reproducible among pediatric emergency medicine physicians, radiologists, and orthopedic surgeons.

RESUMEN

BACKGROUND: Pediatric supracondylar humerus (SCH; AO/OTA13-M/3.1) and medial epicondyle fractures (AO/OTA13u-M/7.1) are common. Concomitant SCH with ipsilateral medial epicondyle fractures remain scarcely reported. We investigated the epidemiology, treatment, and outcomes of this rare, combined injury. METHODS: A retrospective review of pediatric patients with concomitant SCH and medial epicondyle fractures at a level 1 hospital from 2010 to 2020 was performed. Patient data, treatments, and outcomes were assessed. Radiographs were reviewed for fracture classification and alignment. Patients aged above 18 years and those with inaccessible imaging were excluded. Descriptive statistics were performed. RESULTS: Of 3344 patients undergoing surgery for SCH fractures, 14 (6 females, mean: 10.59 y) with concomitant SCH and medial epicondyle fractures were included. Overall, 28.6% of patients exhibited preoperative nerve palsies (3 PIN, 1 median nerve). There was 1 flexion type and 13 Gartland type III SCH fractures. Medial epicondyle fracture displacement averaged 4.13 mm (range: 2 to 7 mm). Thirteen medial epicondyle fractures occurred medial to the physis with 1 through the physis. Eight patients (57.1%) had medial fixation-7 medial pins, 1 medial screw-which captured both the medial epicondyle and medial column of the SCH fracture. Six medial epicondyles were treated closed. The average time to pin pull was 33.1 days (range: 27 to 51 d) with average follow-up of 138.6 days (range: 27 to 574 d). Overall, 50% of patients completed physical therapy (PT). Complications occurred in 4 cases: prominence of a medial pin, 1 patient required additional PT and dynamic splinting for loss of functional extension, 1 patient underwent a manipulation under anesthesia 3.5 months postoperatively for flexion contracture, and 1 patient developed medial epicondyle nonunion and SCH malunion that underwent corrective osteotomy 10.5 months postoperatively. CONCLUSIONS: Concurrent SCH and medial epicondyle fractures exhibited a high rate of nerve palsy (28.6%) and complications (28.6%) and were frequently referred to physical therapy. While patients treated without medial fixation went on to union, this combined injury might represent a relative indication for medial pinning of the SCH fracture. Further studies on this rare injury pattern are needed to determine optimal treatment methods. LEVEL OF EVIDENCE: Level IV-therapeutic.

RESUMEN

OBJECTIVE: Chat generative pre-trained transformer (ChatGPT) has garnered attention in health care for its potential to reshape patient interactions. As patients increasingly rely on artificial intelligence platforms, concerns about information accuracy arise. In-toeing, a common lower extremity variation, often leads to pediatric orthopaedic referrals despite observation being the primary treatment. Our study aims to assess ChatGPT's responses to pediatric in-toeing questions, contributing to discussions on health care innovation and technology in patient education. METHODS: We compiled a list of 34 common in-toeing questions from the "Frequently Asked Questions" sections of 9 health care-affiliated websites, identifying 25 as the most encountered. On January 17, 2024, we queried ChatGPT 3.5 in separate sessions and recorded the responses. These 25 questions were posed again on January 21, 2024, to assess its reproducibility. Two pediatric orthopaedic surgeons evaluated responses using a scale of "excellent (no clarification)" to "unsatisfactory (substantial clarification)." Average ratings were used when evaluators' grades were within one level of each other. In discordant cases, the senior author provided a decisive rating. RESULTS: We found 46% of ChatGPT responses were "excellent" and 44% "satisfactory (minimal clarification)." In addition, 8% of cases were "satisfactory (moderate clarification)" and 2% were "unsatisfactory." Questions had appropriate readability, with an average Flesch-Kincaid Grade Level of 4.9 (±2.1). However, ChatGPT's responses were at a collegiate level, averaging 12.7 (±1.4). No significant differences in ratings were observed between question topics. Furthermore, ChatGPT exhibited moderate consistency after repeated queries, evidenced by a Spearman rho coefficient of 0.55 ( P = 0.005). The chatbot appropriately described in-toeing as normal or spontaneously resolving in 62% of responses and consistently recommended evaluation by a health care provider in 100%. CONCLUSION: The chatbot presented a serviceable, though not perfect, representation of the diagnosis and management of pediatric in-toeing while demonstrating a moderate level of reproducibility in its responses. ChatGPT's utility could be enhanced by improving readability and consistency and incorporating evidence-based guidelines. LEVEL OF EVIDENCE: Level IV-diagnostic.

RESUMEN

PURPOSE: This qualitative descriptive study aimed to explore the daily experiences of caregivers of children with medical complexity with a tracheostomy at home. METHODS: This study used photovoice, a participatory action research methodology. Adult English-speaking caregivers of children with a tracheostomy, living in Texas, with access to a smartphone were recruited. Photographs taken by participants and an interview guide were used to guide semi-structured interviews with caregivers. RESULTS: Eight participants were recruited. After analyzing photographs and caregiver interviews, four main themes were identified: role transition, daily challenges, finding support, and thriving in the new normal. CONCLUSIONS: Caregivers take on multiple roles, including providing medical care, advocating for their children, and educating others. While facing emotional challenges such as guilt, fear, and exhaustion, caregivers rely on external support systems, emphasizing the need for nurses and healthcare providers to provide comprehensive support and improve the accessibility of home nursing services. PRACTICE IMPLICATIONS: The findings of this study can inform nurse-led interventions and advocacy efforts aimed at supporting marginalized children with medical complexity with a tracheostomy and their families. These efforts may include enhancing communication and collaboration between families, healthcare workers, and the public, providing comprehensive, proactive support for caregivers, and improving access to home nursing services.

RESUMEN

PURPOSE: Necrotizing fasciitis (NF) is a rare, but rapidly progressing bacterial infection of the subcutaneous tissues and muscular fascia with high rates of morbidity and mortality. Our study aims to determine if socioeconomic status (SES) is a predictor of outcomes in NF. METHODS: A retrospective review was conducted of patients diagnosed with NF at our institution. Demographic information, insurance status, medical and surgical history, vitals, ASA score, blood laboratory values, surgical procedure information, and outcomes prior to patient discharge were collected. Patient zip codes were utilized to obtain median household incomes at the time of the patient's surgical procedure to determine SES. Patients without complete data in their medical record were excluded. Initial descriptive statistics and logistic regression models were performed. RESULTS: We identified 196 patients (mean age 50.13 ± 13.03 years, 31.6% female) for inclusion. Mortality rate was 15.3% (n = 30) and 33.7% (n = 66) underwent amputation. Mortality rate was not significantly different across income brackets. Lower income brackets had higher rates of amputation than higher income brackets (p < 0.05). A logistic regression models showed the rate of amputation decreases by 29% for every $10,000 increment in median household income and ASA score decreased by 0.15 units for every $10,000 increase in median household income. CONCLUSIONS: Amputation rates in cases of NF are significantly higher in lower SES groups than higher SES groups. Patients with perivascular disease in lower SES groups were more likely to experience serious complications of NF than their counterparts in higher SES groups.

RESUMEN

OBJECTIVE: The aim of this study was to describe the characteristics and outcomes of remote-dwelling pregnant women with threatened labor referred for air medical retrieval to a regional birthing center as well as factors associated with birth within 48 hours. METHODS: This was a retrospective observational study of all pregnant women in the remote Central Australian region referred to the Medical Retrieval Consultation and Coordination Centre for labor > 23 weeks' gestation between February 12, 2018, and February 12, 2020. Univariate and multivariate statistical analyses were performed. RESULTS: There were 116 women referred for retrieval for labor. There were no births during transport, and less than half of the cases resulted in birth within 48 hours of retrieval. Tocolysis was frequently used. Predictors of birth within 48 hours were cervical dilatation ≥ 5 cm, preterm gestational age, and ruptured membranes in the univariate analysis. Nearly one third of this cohort required intervention or had complications during birth. CONCLUSION: Birth during transport for threatened labor did not occur in this cohort, and more than half of the retrievals did not result in birth within 48 hours; however, the high risk of birth complications may offset any benefit of avoiding air medical transport from remote regions. Retrieval clinicians should consider urgent transfer in cases of ruptured membranes, cervical dilatation of 5 cm or more, or gestational age less than 37 weeks.

RESUMEN

Cysteine dioxygenase (CDO) is a non-heme iron-containing enzyme that catalyzes the oxidation of cysteine (Cys) to cysteine sulfinic acid (CSA). Crystal structures of eukaryotic CDOs revealed the presence of an unusual crosslink between the sulfur of a cysteine residue (C93 in Mus musculus CDO, MmCDO) and a carbon atom adjacent to the phenyl group of a tyrosine residue (Y157). Formation of this crosslink occurs over time as a byproduct of catalysis and increases the catalytic efficiency of CDO by at least 10-fold. Interestingly, in bacterial CDOs, the residue corresponding to C93 is replaced by a highly conserved glycine (G82 in Bacillus subtilis CDO, BsCDO), which precludes the formation of a C-Y crosslink in these enzymes; yet bacterial CDOs achieve turnover rates paralleling those of fully crosslinked eukaryotic CDOs. In the present study, we prepared the G82C variant of BsCDO to determine if a single DNA point mutation could lead to C-Y crosslink formation in this enzyme. We used gel electrophoresis, peptide mass spectrometry, electron paramagnetic resonance spectroscopy, and kinetic assays to characterize this variant alongside the natively crosslinked wild-type (WT) MmCDO and the natively non-crosslinked WT BsCDO. Collectively, our results provide compelling evidence that the G82C BsCDO variant is indeed capable of C-Y crosslink formation. Our kinetic studies indicate that G82C BsCDO has a reduced catalytic efficiency compared to WT BsCDO and that activity increases as the ratio of crosslinked to non-crosslinked enzyme increases. Finally, by carrying out a bioinformatic analysis of the CDO family, we were able to identify a large number of putatively crosslinked bacterial CDOs, the majority of which are from Gram-negative pathogenic bacteria.

RESUMEN

OBJECTIVES: Impaired nitric oxide (NO) bioavailability may contribute to microvascular dysfunction in sepsis. Excessive plasma NO consumption has been attributed to scavenging by circulating cell-free hemoglobin. This may be a mechanism for NO deficiency in sepsis and critical illness. We hypothesized that plasma NO consumption is high in critically ill patients, particularly those with sepsis, acute respiratory distress syndrome (ARDS), shock, and in hospital nonsurvivors. We further hypothesized that plasma NO consumption is correlated with plasma cell-free hemoglobin concentration. DESIGN: Retrospective cohort study. SETTING: Adult ICUs of an academic medical center. PATIENTS AND SUBJECTS: Three hundred sixty-two critically ill patients and 46 healthy control subjects. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Plasma NO consumption was measured using reductive chemiluminescence and cell-free hemoglobin was measured with a colorimetric assay. Mean (95% CI) plasma NO consumption (µM) was higher in critically ill patients versus healthy control subjects (3.9 [3.7-4.1] vs 2.1 [1.8-2.5]), septic versus nonseptic patients (4.1 [3.8-4.3] vs 3.6 [3.3-3.8]), ARDS versus non-ARDS patients (4.4 [4.0-4.9] vs 3.7 [3.6-3.9]), shock vs nonshock patients (4.4 [4.0-4.8] vs 3.6 [3.4-3.8]), and hospital nonsurvivors versus survivors (5.3 [4.4-6.4] vs 3.7 [3.6-3.9]). These relationships remained significant in multivariable analyses. Plasma cell-free hemoglobin was weakly correlated with plasma NO consumption. CONCLUSIONS: Plasma NO consumption is elevated in critically ill patients and independently associated with sepsis, ARDS, shock, and hospital death. These data suggest that excessive intravascular NO scavenging characterizes sepsis and adverse outcomes of critical illness.

RESUMEN

The p-21-activated kinase 1 (PAK1) protein, encoded by the PAK1 gene, is an evolutionarily conserved serine/threonine-protein kinase that regulates key cellular developmental processes. To date, seven de novo PAK1 variants have been reported to cause the Intellectual Developmental Disorder with Macrocephaly, Seizures, and Speech Delay (IDDMSSD). In addition to the namesake features, other common characteristics include structural brain anomalies, delayed development, hypotonia, and dysmorphic features. Here, we report a de novo PAK1 NM_002576.5: c.1409 T > A variant (p.Leu470Gln) identified by trio genome sequencing (GS) in a 13-year-old boy with postnatal macrocephaly, obstructive hydrocephalus, medically refractory epilepsy, spastic quadriplegia, white matter hyperintensities, profound developmental disabilities, and a horseshoe kidney. This is the first recurrently affected residue identified in the protein kinase domain. Combined assessment of the eight pathogenic PAK1 missense variants reveal that the variants cluster in either the protein kinase or autoregulatory domains. Although interpretation of the phenotypic spectrum is limited by the sample size, neuroanatomical alterations were found more often in individuals with PAK1 variants in the autoregulatory domain. In contrast, non-neurological comorbidities were found more often in individuals with PAK1 variants in the protein kinase domain. Together, these findings expand the clinical spectrum of PAK1-associated IDDMSSD and reveal potential correlations with the affected protein domains.

RESUMEN

OBJECTIVES: Many children with epilepsy experience seizures at school. School nurses must have the clinical expertise to deliver high-quality, safe care for students with epilepsy. However, in some regions of the U.S. access to interactive, epilepsy evidence-based education programs is limited. The objective of this project was to assess the feasibility of adapting the Epilepsy Foundation's (EFs) school nurse education program to the ECHO model and evaluate its impact on school nurse knowledge and self-efficacy in managing epilepsy in students with seizures and program satisfaction. METHODS: The EFs educational program for school nurses was adapted to the ECHO model and delivered by a team of interdisciplinary epilepsy specialists via videoconferencing. Retrospective post-program surveys were administered at program completion. Data from 32 participants with complete post-program surveys were used for the analysis of knowledge and confidence. Descriptive statistics and the sign test were conducted. RESULTS: Participants were 166 school nurses from 13 states. The majority had > 15 years of school nurse experience and served schools in suburban or rural areas. Improvements in knowledge and confidence were reported on most survey items. The highest improvements in self-reported knowledge and confidence were in psychosocial aspects of care, comorbidities, and recognition of nonepileptic events. Program satisfaction was rated as high by over 90% of participants. CONCLUSIONS: Telementoring using the ECHO methodology is a feasible modality to educate and link epilepsy specialists and providers with school nurses nationwide. Findings suggest that attending the MSS ECHO provided an educational and meaningful learning experience. The gains in knowledge and confidence in psychosocial aspects of epilepsy care and comorbidities highlight the importance of the inclusion of this content in educational programs.

RESUMEN

PURPOSE: The purpose of this study was to understand the experiences of parents and caregivers of children with special healthcare needs during the COVID-19 pandemic. DESIGN AND METHODS: In this descriptive phenomenological study, the researchers used purposive and snowball sampling to recruit nineteen participants, ranging in age from 21 to 55 years of age until saturation was established. Colaizzi's method guided data analysis. Iterative examination of the interview transcripts, an audit trail, bracketing, and validation of findings with a subset of participants established trustworthiness. RESULTS: Navigating the COVID-19 Pandemic was the overarching theme. Four major themes emerged under Navigating the COVID-19 Pandemic as follows: Disruptions in Daily Life, Shifts in Daily Life, Innovations in Daily Life, and Surprising Silver Linings. CONCLUSION: This study elucidated an in-depth understanding of the positive and negative impacts of the pandemic on the lives of families living with a child with special needs. The COVID-19 pandemic profoundly affected families and parenting approaches. Parents of children with special healthcare needs in this study found day-to-day living especially difficult in similar and unique ways. For virtually all parents the pandemic added new challenges in meeting their child's physical, mental, social, and educational needs. Parents and caregivers revealed innovative ways of maintaining a sense of normalcy during the height of the pandemic. PRACTICE IMPLICATIONS: These findings demonstrate the importance of developing interventions and creating public health policies as we move beyond the current pandemic and plan for potential outbreaks in the future.

RESUMEN

OBJECTIVES: We report the development and validation of a tool to assess gastrointestinal health in Rett syndrome (RTT). We hypothesized that the Gastrointestinal Health Questionnaire (GHQ) is a valid clinical outcomes measure of gastrointestinal health in RTT. PATIENTS AND METHODS: We used parent interviews, surveys, and literature review to generate a questionnaire related to gastrointestinal health and function, mood and behaviors, and parental concerns for individuals with RTT. Parents of affected and unaffected individuals provided responses to the GHQ, assessed the relevance and importance of statements, and completed 5 surveys related to gastrointestinal health, child-related mood and behaviors, and parent concerns. We used multivariate item analysis, 2-sample t tests, and correlations to assess the validity of the GHQ. RESULTS: We documented acceptable internal consistency of statements related to gastrointestinal health and function (Cronbach-α = 0.91), RTT-related mood and behaviors (Cronbach-α = 0.89), and parent concerns (Cronbach-α = 0.95) in the GHQ. We documented favorable external validity based on differences in response scores between parents of affected and unaffected individuals (P < 0.001) and correlations in parental response scores between the GHQ and 5 validated questionnaires addressing similar issues (P < 0.001). CONCLUSION: The GHQ is a valid tool for the assessment of gastrointestinal health in RTT and offers the opportunity to field test the safety and efficacy of novel drug therapies in clinical trials for individuals affected with this disorder.

RESUMEN

Asthma is a common disease in children, and obtaining basic knowledge and skills to manage asthma symptoms is critically important. This study examined the effectiveness of a theoretically based school nurse-led asthma intervention on asthma symptoms, self-management, peak flow meter usage, daily activities, and school absences in children 7-12 years old. A randomized controlled, two-group, repeated measures design was conducted in eight public schools. Data collection occurred at three time points. The treatment group had statistically significant differences in reported symptoms (p < .001), asthma control with a peak flow meter usage (p < .001), and daily activities (p < .001) at 6 weeks and at 12 weeks. Although difference in school absences was not statistically significant, the treatment group missed fewer school days than the control group. Self-management is a complex process, and school nurses can provide essential learning steps and continuity of care for school-age children living with asthma.

RESUMEN

The trimeric nature of the Fenna-Matthews-Olson (FMO) protein antenna complex from green sulfur phototrophic bacteria was investigated. Mutations were introduced into the protein at positions 142 and 198, which were chosen to destabilize the intra-trimer salt bridges between adjacent monomers. Strains bearing the mutations R142L, R198L, or their combination, exhibited altered optical absorption spectra of purified membranes and fluoresced more intensely than the wild type. In particular, the introduction of the R142L mutation resulted in slower culture growth rates, as well as an FMO complex that was not able to be isolated in appreciable quantities, while the R198L mutation yielded an FMO complex with increased sensitivity to sodium thiocyanate and Triton X-100 treatments. Native and denaturing PAGE experiments suggest that much of the FMO complexes in the mutant strains pool with the insoluble material upon membrane solubilization with n-dodecyl ß-D-maltoside, a mild nonionic detergent. Taken together, our results suggest that the quaternary structure of the FMO complex, the homotrimer, is an important factor in the maintenance of the complex's tertiary structure.

RESUMEN

OBJECTIVE: To respond to recommendations put forth by the Institute of Medicine to improve self-management resources for youth with epilepsy by conducting a systematic review of the self-management literature in pediatric epilepsy. METHODS: Inclusion criteria: youth birth to 18 years with a seizure disorder or an epilepsy diagnosis and/or their caregivers, published 1985-2014 in English, and conducted in countries with a very high human development index. Abstract and keywords had to explicitly refer to "self-care" (pre-1996) and/or self-management (post-1996). The review was conducted in seven phases: (1) identification of bibliographical search criteria and databases; (2) abstract assessment; (3) full article review; (4) organization of final citations into instrument development, intervention, factors associated with self-management categories; (5) American Academy of Neurology level of evidence (LOE) assessment for intervention studies; (6) CONsolidated Standards of Reporting Trials (CONSORT) evaluation of LOE level III articles utilizing a control group; and (7) categorization of intervention outcomes across four self-management domains. RESULTS: Of the 87 articles that met eligibility criteria, 24 were interventions and received LOE scores of level III or IV. Most studies (n = 20, 80%) were scored at level III; however, only eight had a control group and adhered to CONSORT guidelines. They largely neglected information on intervention components (e.g., implementation, treatment fidelity), randomization, participant flow, missing data, and effect size or confidence intervals. The 24 intervention studies reported significant impact in four domains: individual (n = 13), family (n = 6), health care system (n = 3), and community (n = 2). SIGNIFICANCE: There are no level I or II studies. No study met full CONSORT guidelines. Outcomes were well described; however, the nature of self-management interventions (e.g., multiple foci, skills targeted) and the observed heterogeneity in outcomes complicates comparisons across studies. Randomized controlled trials (RCTs) that include large sample sizes, impact of the intervention, treatment fidelity, and power analyses are necessary to further this evidence base.

RESUMEN

We examined benefits and risks for memory and academic functioning associated with epilepsy surgery in a pediatric population. A total of 46 patients with intractable seizures and a single seizure focus were divided into four groups according to focus localization: right temporal, left temporal, frontal, and parietal/occipital region. Pre- and postsurgery performance measures were compared across groups and with a fifth group of patients that had intractable seizures but did not undergo surgery. Both groups with temporal lobe epilepsy showed significant declines in memory test scores, while performance of the group with frontal lobe epilepsy improved. These changes were mirrored in parental reports of everyday memory. Consistent with other pediatric studies, no lateralized material-specific declines in the groups with temporal lobe epilepsy were found. When memory improved, the improvement was associated with decreases in seizure frequency and the number of anticonvulsant medications. Presurgical performance was the best predictor of declines in memory test performance.

RESUMEN

BACKGROUND: Intracarotid amobarbital procedure (IAP) is acknowledged as the gold standard test for language lateralization. EEG is performed routinely during IAP to monitor the anesthetization of a brain hemisphere. Here, we studied the correlation between the early EEG changes using envelope trend and the clinical outcome of IAP. METHOD: Fifty consecutive patients underwent IAP at Texas Children's Hospital (2004-2009). Intracarotid amobarbital procedure was considered "complete" or "incomplete" based on the outcome if the procedure was completed or aborted due to behavior changes. Envelope trend was used to calculate the median EEG amplitude changes within the first 60s of IAP. Statistical analysis was performed to determine the role of EEG changes and clinical features on the procedure outcome. RESULTS: Only 30 IAP-EEG files were available for review. Amobarbital was administered at the dose of 60-150mg (mean: 110±20). The intracarotid amobarbital procedure was recorded as complete in 23 patients and incomplete in 7 patients. EEG changes occurred within the first few seconds following amobarbital injection. Following amobarbital injection, focal slowing was present in the ipsilateral frontal region or both ipsilateral and contralateral frontal regions. Elapsed time to the first EEG change or duration and change in median EEG amplitude in the ipsilateral frontal regions were indifferent between the complete and incomplete groups (p>0.05). However, the median amplitude changes between the ipsilateral and contralateral frontal regions within each group were found significant only in the complete group (p<0.05), suggesting ipsilateral without contralateral frontal slowing. Other than age at the time of IAP (p=0.03), none of the other clinical features correlated with the clinical outcome of IAP (p>0.05). CONCLUSION: Early EEG changes during IAP using envelope trend may predict successful completion of the IAP test. Younger children are at risk of behavioral changes during IAP.

RESUMEN

Background: Organ transplantation is a well-established intervention but is reliant on the donation of organs and tissues, mostly from deceased donors. The proportion of Australians proceeding to organ donation (OD) has increased, but the proportion of Indigenous Australians proceeding remains two-thirds that of non-Indigenous Australians. We sought to explore perceived barriers and enablers for the involvement of Indigenous peoples in the OD process. Methods: Qualitative methodology centered around focus groups was used to capture the experiences and perspectives of Indigenous people regarding OD. A purposively sampled group of Aboriginal Liaison Officers working within the Alice Springs Hospital Intensive Care Unit (ASH ICU) participated in up to 6 focus groups during 2021 with subsequent thematic analysis of the enablers and barriers to Indigenous participation in the OD process. The ASH ICU is the only ICU servicing Central Australia, and 70% of admissions are Indigenous patients. Results: Four primary themes emerged: OD is a new and culturally taboo topic; conversations related to OD are confronting; education is needed (both about OD and cultural education for clinicians); and lack of trust in the healthcare system. Conclusions: There are cultural barriers to engaging in the OD process and clinicians need more training on the delivery of culturally safe communication is needed. Despite this, there was a recognition that OD is important. Education about OD needs to be place based, culturally and linguistically appropriate, informed by local knowledge, delivered in community, and occur before a family member is admitted to ICU.

RESUMEN

Introduction: Workplace violence is endemic, destructive, and escalating in frequency and severity in healthcare. There is a paucity of research on workplace violence in regional and remote hospital emergency departments (EDs). Objective: The aim of this study was to identify the perpetrator and situational characteristics associated with violent incidents in the ED across five regional and remote Australian sites. Method: This study audited hospital summary data, incident reports, and medical records for a 12-month period in 2018 to examine the perpetrator and situational characteristics of workplace violence incidents in five regional and remote Australian EDs. Results: Violent incidents were evenly spread throughout the week and across shifts. Most incidents were triaged as urgent, occurred within the first 4 hr, and had multidisciplinary involvement. Almost one in every six incidents resulted in an injury. Perpetrators of violence were predominantly young and middle-aged males and almost always patients, with most presenting with mental and behavioral disorders, or psychoactive substance use. Conclusions: Understanding the characteristics of perpetrators of violence can help in seeking to tailor interventions to reduce further violent behaviors. These findings carry implications for optimizing patient care, staff safety and resource management.
