Gartland classification concordance of supracondylar fractures among pediatric emergency medicine physicians, radiologists, and orthopedic surgeons.

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.

Evaluating Chat Generative Pre-trained Transformer Responses to Common Pediatric In-toeing Questions.

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.

Musculoskeletal injections for palliative treatment of neuromuscular hip dysplasia patients: how I do it.

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.

Air Medical Retrieval of Central Australian Women in Labor: A Retrospective Observational Study.

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.

Plasma Nitric Oxide Consumption Is Elevated and Associated With Adverse Outcomes in Critically Ill Patients.

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.

A Single DNA Point Mutation Leads to the Formation of a Cysteine-Tyrosine Crosslink in the Cysteine Dioxygenase from Bacillus subtilis.

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.

Refractory compartment syndrome after antivenom administration for an Eastern Diamondback Rattlesnake bite requiring fasciotomy for limb salvage: A case report.

Case: 56-year-old male who developed post-snakebite compartment syndrome (PSCS) of the upper extremity which was refractory to antivenom administration. He had elevated compartment pressure measurements in his upper extremity. He underwent open fasciotomy for the compartment syndrome, followed by delayed primary closure and skin grafting. He now has two years of follow-up with a functional upper extremity. Conclusion: This is a case of a patient who suffered post-snakebite compartment syndrome from his pet Eastern Diamondback Rattlesnake. This case highlights the importance of correctly diagnosing compartment syndrome and validates fasciotomy as a treatment measure for confirmed post-snakebite compartment syndrome (PSCS).

Thoracic Spinal Stenosis From Calcified Ligamentum Flavum.

Background: Calcification of the ligamentum flavum is a rare cause of spinal stenosis. The process can occur at any level in the spine, often presents with local pain or radicular symptoms, and is a distinct process from ossification of the spinal ligaments in pathogenesis and treatment approach. Few case reports have described multiple level involvement in the thoracic spine that results in sensorimotor deficits and myelopathy. Case Report: A 37-year-old female presented with progressive sensorimotor deficits from T3 distally that resulted in complete sensory deficits and diminished lower extremity strength. Computed tomography and magnetic resonance imaging demonstrated calcification of the ligamentum flavum from T2-T12 with severe spinal stenosis at T3-T4. She underwent T2-T12 posterior laminectomy with ligamentum flavum resection. Postoperatively, she had complete motor strength return and was discharged home for outpatient therapy. Her residual sensory deficits continued to improve with time after decompression and excision of the calcified ligamentum flavum. Conclusion: This case is unique in that the calcific process involved nearly the entire thoracic spine. The patient had dramatic improvement in her symptoms following resection of the involved levels. The case adds a severe manifestation of calcification of the ligamentum flavum with a surgical outcome to the literature.

Parents voice their experiences of caring for children with special healthcare needs amid the COVID-19 pandemic.

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.

Integrating Tobacco Dependence Treatment into Hospital Practice Using the Rochester Model.

Purpose: Delivering evidence-based tobacco dependence treatments to hospital patients in real-world settings continues to be a challenge. To achieve long-term abstinence, a program should provide both bedside counseling and post-discharge contacts. These program features are necessary but difficult to implement due to lack of training, time and low administrative support. The Rochester Model is a tobacco treatment program using existing staff and medical students to reduce the barriers for treating hospitalized smokers. Patients and Methods: Any smoking patient admitted to a participating hospital unit can participate. Staff nurses, mid-level providers and physicians deliver the counseling steps during the admission. Nurses hold two bedside counseling sessions, while providers give quitting advice and encourage pharmacotherapy. Nurses also contribute as unit champions and post-discharge call counselors. New York State quit line counselors combined with a University of Rochester call team fulfill the post-discharge calls. The latter call team is composed of staff nurses, respiratory therapists and medical students. Results: The number of smoking patients screened was 2610 while 385 enrolled after a proof-of-concept period. The 7-day point prevalence quit rates using the as treated (patients contacted) analysis is 50% at 4 weeks, 42% at 3 months and 38% at 6 months. The 7-day point prevalence quit rates using the intent-to-treat (all patients) analysis is 23% at 4 weeks, 16% at 3 months and 14% at 6 months. Conclusion: Preliminary data on the Rochester Model is showing an effective yet affordable tobacco treatment program using hospital staff and medical students. Nurses serve as bedside counselors, unit champions and post-discharge call counselors. Hospitals, even with limited resources, can implement tobacco treatment programs using existing staff.

Hypokalemia-Induced Life-Threatening Arrhythmia in a Patient With Congestive Heart Failure.

Ventricular tachyarrhythmias are common in patients with heart failure. It is one of the important preventable causes of death in these patient populations. Hypokalemia is prevalent in patients with heart failure due to various reasons. Hypokalemia can trigger ventricular arrhythmias through different mechanisms. In this case report, we present a middle-aged man with congestive heart failure (CHF) and an automated intracardiac defibrillator (AICD) on multiple diuretic medications (unintended) who presented with acute chest pain. He was found to have severe hypokalemia, hyponatremia, and an acute kidney injury. Interrogation of the AICD revealed multiple episodes of ventricular fibrillation. The patient was managed by holding his diuretic medications, cautious volume repletion, and potassium replacement. Fortunately, the patient showed rapid clinical improvement and his plasma potassium level improved. On discharge, we reconciled the patient's medications to avoid the recurrence of hypokalemia from over-diuresis and arranged a close follow-up outpatient visit with his cardiologist.

PAK1 c.1409 T > a (p. Leu470Gln) de novo variant affects the protein kinase domain, leading to epilepsy, macrocephaly, spastic quadriplegia, and hydrocephalus: Case report and review of the literature.

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.

Project ECHO telementoring program in epilepsy for school nurses.

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.

Medical retrieval of pregnant women in labour: A scoping review.

BACKGROUND: Remote Australian women in labour often rely on retrieval services to allow birthing in specialist obstetric centres. However, there is currently debate over when not to transfer a woman in labour, for risk of an in-transit birth, associated with worse neonatal outcomes. METHODS: A scoping review methodology was undertaken, to define the scope of published literature on the topic and identify gaps in the current knowledge. RESULTS: A total of seven full texts were deemed suitable for synthesis, which were all retrospective observational studies. Four themes from the studies' findings were identified: population features, predicting time-to-birth, use of tocolysis and birth during medical evacuation. CONCLUSION: The evidence identified in this review was of low methodological quality and heterogenous. The key findings were that births in-flight are rare, despite geographical distances and long transport times, with a knowledge gap on predictors of time-to-birth.

The Effect of Heat Events on Prehospital and Retrieval Service Utilization in Rural and Remote Areas: A Scoping Review.

INTRODUCTION: It is well-established that heatwaves increase demand for emergency transport in metropolitan areas; however, little is known about the impact of heat events on demand for prehospital retrieval services in rural and remote areas, or how heatwaves are defined in this context. INCLUSION CRITERIA: Papers were eligible for inclusion if they reported on the impact of a heat event on the activity of a prehospital and retrieval service in a rural or remote area. METHODS: A search of PubMed, Cochrane, Science Direct, CINAHL, and Google Scholar databases was undertaken on August 18, 2020 using search terms related to emergency medical transport, extreme heat, and rural or remote. Data relevant to the impact of heat on retrieval service activity were extracted, as well as definitions of extreme heat. RESULTS: Two papers were identified, both from Australia. Both found that heat events increased the number of road ambulance call-outs. Both studies used the Excess Heat Factor (EHF) to define heatwave periods of interest. CONCLUSIONS: This review found almost no primary literature on demand for prehospital retrieval services in rural and remote areas, and no data specifically related to aeromedical transport. The research did recognize the disproportionate impact of heat-related increase in service demand on Australian rural and regional health services. With the effects of climate change already being felt, there is an urgent need for more research and action in this area.

ECHO Telementoring Applied to Managing Students With Seizures: The Benefits for School Nurses.

Project ECHO (Extension for Community Healthcare Outcomes) is an evidence-based telementoring approach to connect often siloed school nurses with a network of expert clinical and academic faculty, as well as school nurse colleagues throughout the country by engaging in case-based learning. Managing Students with Seizures ECHO: The Importance of School Nurses (MSwS ECHO) provided two cohorts of school nurses with an interactive, bidirectional educational program focused on various aspects of seizures and epilepsy relevant to school nurse practice. MSwS ECHO enhanced school nurses' confidence in caring and advocating for students with seizures and epilepsy, expanded school nurses' access to resources and professional networks, and provided the opportunity to collaborate with experts and colleagues to problem solve challenging real-life cases. The ECHO Model is a unique and effective teaching modality that can be applied to a variety of school health topics and chronic conditions. School nurses are encouraged to participate in forthcoming ECHO-based learning opportunities.

Remote area nursing: best practice or paternalism in action? The importance of consumer perspectives on primary health care nursing practice in remote communities.

This paper reports on a study that aimed to understand how remote area nurses implemented primary health care principles in the Australian remote health care setting. Twenty-four Registered Nurses and Nurse Practitioners who worked in remote health services without inpatient facilities were interviewed using constructivist grounded theory methods. Findings revealed that nurses in this study aimed to practice in a way that was guided by Indigenous empowerment and social justice. However, some nurses questioned elements of their practice such as 'chasing' people for appointments or routine screening required by clinical guidelines that may not reflect the values of Indigenous peoples. Nurses expressed concern that they may be reinforcing past colonising practices and their actions may be considered paternalistic rather than empowering. Nurses in this study wanted to develop partnerships and provide nursing care that aligned with the health and wellbeing expectations of communities. However, ways of communicating the needs of communities and the development of partnerships between health providers and communities need to be developed. The present study calls for further research from the perspective of remote community members in order to develop ways of sharing knowledge about health and wellbeing between remote area nurses and communities.

Gastrointestinal Health Questionnaire for Rett Syndrome: Tool Development.

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.

A School Nurse-Led Asthma Intervention for School-Age Children: A Randomized Control Trial to Improve Self-Management.

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.
