Measuring Pectus Excavatum Severity, External Caliper, or Cross-Sectional Imaging: Family Perceptions.

INTRODUCTION: Patients with pectus excavatum (PE) often undergo cross-sectional imaging (CSI) to quantify severity for insurance authorization before surgical repair. The modified percent depth (MPD), an external caliper-based metric, was previously validated to be similar to the pectus index and correction index. This study explored family perceptions of CSI and MPD with respect to value and costs. METHODS: This is a cross-sectional survey study including families of patients enrolled in an ongoing prospective multicenter study evaluating the use of MPD as an alternative to CSI for quantifying PE severity. Families of PE patients who underwent both MPD and CSI completed a survey to determine their perceptions of MPD and costs of CSI. Responses were described and associations were evaluated using chi squared, Wilcoxon rank-sum test and logistic regression as appropriate. Statistical significance was set to 0.05. RESULTS: There were 136 surveys completed for a response rate of 88%. Respondents were confident in MPD (86%) and confident in its similarity to CSI (76%). Families of females were less confident in the measurements than males (55% versus 80%, P = 0.02; odds ratio 0.30 (0.11, 0.83). Obtaining CSI required time off work/school in 90% and a copay in 60%. Nearly half (49%) of respondents reported CSI was a time/financial hardship. Increasing copay led to decreased reassurance in CSI (55%: copay > $100 versus 77%: lower copay/75%: no copay; P = 0.04). CONCLUSIONS: From the family perspective, MPD is valuable in assessing the severity of PE. Obtaining CSI was financially burdensome, particularly for those with higher copays. MPD measurements provide high value at low cost in assessing the severity of PE.

Disparities in insurance status negatively affect patients with infantile hypertrophic pyloric stenosis.

PURPOSE: Infantile hypertrophic pyloric stenosis (IHPS) is suspected to have worse outcomes when length of illness prior to presentation is prolonged. Our objective was to evaluate how social determinants of health influence medical care and outcomes for babies with IHPS. METHODS: A retrospective review was performed over 10 years. Census data were used as proxy for socioeconomic status via Geo-Identification codes and correlated with food access and social vulnerability variables. The cohort was subdivided to understand the impact of Medicaid Managed Care (MMC). RESULTS: The cohort (279 cases) was divided into two groups; early group from 2011 to 2015 and late from 2016 to 2021. Cases in the late group were older at the time of presentation (41.5 vs. 36.5 days; p = 0.022) and presented later in the disease course (12.8 vs. 8.9 days; p = 0.021). There was no difference in race (p = 0.282), gender (p = 0.874), or length of stay. CONCLUSIONS: Patients who presented with IHPS after implementation of phased MMC were older, had a longer symptomatic course, and shorter pylorus measurements. Patients with public insurance after the implementation of MMC were more likely to follow-up with an outpatient pediatrician within a month of hospitalization. These results suggest that MMC may have improved access to care for infants with IHPS.

Exploring Limited English Proficiency in the Clinical Outcomes of Pediatric Burn Patients.

INTRODUCTION: Limited English proficiency (LEP) is linked to lower health care access and worse clinical outcomes. This study aims to explore the potential role of LEP on clinical outcomes of pediatric burn patients. METHODS: We conducted a single-institution retrospective study of burn patients presenting at a tertiary pediatric burn referral program between January 2016 and December 2020. Patient demographics, burn mechanism, severity, interventions, and primary patient language were abstracted from the electronic health record. Clinical outcomes (length of stay [LOS], clinic follow-up, and 30-day readmission) of patients with LEP were compared to patients with English as primary language (EPL). RESULTS: Thirty-five (4.2%) patients with LEP were identified of 840 total patients. On univariate analysis, there was no difference in mean total body surface area (6.5% versus 6.1%), report of physical abuse (2.9% versus 8.9%), or need for grafting (14.3% versus 15.0%) comparing patients with LEP to those with EPL. Patients with LEP were more likely to have a scald burn (68.6% versus 48.9%, P = 0.025) and less likely to have a flame/fire burn (20.0% versus 37.6%, P = 0.047). On multivariate analysis, there was no difference between patients with LEP compared to patients with EPL for LOS (2.9 versus 3.5 d), 30-day readmissions (5.6% versus 5.7%), or clinic follow-up (80.6% versus 75.0%). In patients with >10% total body surface area, patients with LEP had a longer emergency department LOS (277 min versus 145 min, P = 0.06) but no difference in outcome measures. CONCLUSIONS: Pediatric patients with LEP were not found to have worse burn outcomes compared to EPL patients in our patient sample. However, a true association is difficult to determine given the small sample size of LEP patients and the potential underestimation of language discordancy as recorded in the electronic medical record. Further research is needed to better explore the role of primary language and health communication as a social determinant of health in pediatric burn patients.

Vibration Therapy as an Early Intervention for Children Aged 2-4 Years with Cerebral Palsy: A Feasibility Study.

Aims: To evaluate the feasibility and acceptability of vibration therapy (VT) in preschool children with cerebral palsy (CP) and obtain preliminary data on its potential effectiveness.Methods: Nine children aged 2.5-4.8 years (4 boys) with CP GMFCS levels I-III participated in a single-group feasibility study, undergoing a 12-week control period without intervention, followed by 12 weeks of home-based VT (four times/week, 9 min/day, frequency 20 Hz). We assessed adherence to VT protocol, adverse events, and family acceptability of VT. Clinical assessments included motor function (GMFM-66), body composition (DXA), mobility (10-meter walk/run test), and health-related quality of life (PedsQL).Results: VT was well tolerated and acceptable to families, with high adherence levels reported (mean = 93%). There were no observed between-period differences (ΔControl vs ΔVT) except for an improvement in the PedsQL "Movement & Balance" dimension with VT (p = 0.044). Nonetheless, changes after the VT but not the Control period were suggestive of potential treatment benefits for mobility, gross motor function, and body composition (lean mass and legs bone mineral density).Conclusion: Home-based VT is feasible and acceptable for preschool children with CP. Our preliminary data suggest potential health benefits from VT for these children, supporting larger randomized trials to assess its effectiveness properly.

Medical Student Career Choice: Who Is the Influencer?

BACKGROUND: While many factors influence medical student career choice, interactions with attending and resident physicians during clinical rotations are particularly important. To evaluate the influence of attending and resident physicians on medical students' career choices, particularly for those pursuing surgical careers, we quantified their respective influence in the context of other known influences. METHODS: Rising fourth-year medical students and new graduates were given an IRB-exempt, 14-item online survey. Descriptive statistics were performed on the demographic information. Chi-square analysis was used, as were Kruskal-Wallis and Mann-Whitney analyses on the Likert responses (α = 0.05). RESULTS: Survey response was 24%. Students pursuing general surgery rated residents greater than or equal to attendings on 7 of 8 key mentoring characteristics. Of students choosing a different specialty than the one they intended to pursue upon entering medical school, the influence of residents was cited by 100% of the students pursuing general surgery, compared to 59% of the entire cohort. Identification of a role model and perceived personality fit were significantly more important than other factors (P < 0.0001). Students pursuing general surgery rated the importance of identifying a role model and perceived personality fit greater than their peers. CONCLUSIONS: Residents have greater influences on medical students' career choice compared to attendings. Students pursuing a surgical specialty, particularly general surgery, considered the influence of role models and perceived personality fit to be the most important factors in their specialty decision. These findings provide valuable insights to improve student experiences and career recruitment in surgical specialties, particularly general surgery.

Sex-specific relationships between early nutrition and neurodevelopment in preterm infants.

BACKGROUND: Although early nutrition is associated with neurodevelopmental outcome at 2 years' corrected age in children born very preterm, it is not clear if these associations are different in girls and boys. METHODS: Retrospective cohort study of infants born <30 weeks' gestational age or <1500 g birth weight in Auckland, NZ. Macronutrient, energy and fluid volumes per kg per day were calculated from daily nutritional intakes and averaged over days 1-7 (week 1) and 1-28 (month 1). Primary outcome was survival without neurodevelopmental impairment at 2 years corrected age. RESULTS: More girls (215/478) survived without neurodevelopmental impairment at 2 years (82% vs. 72%, P = 0.02). Overall, survival without neurodevelopmental impairment was positively associated with more energy, fat, and enteral feeds in week 1, and more energy and enteral feeds in month 1 (P = 0.005-0.03), but all with sex interactions (P = 0.008-0.02). In girls but not boys, survival without neurodevelopmental impairment was positively associated with week 1 total intakes of fat (OR(95% CI) for highest vs. lowest intake quartile 62.6(6.6-1618.1), P < 0.001), energy (22.9(2.6-542.0), P = 0.03) and enteral feeds (1.9 × 109(9.5-not estimable), P < 0.001). CONCLUSIONS: Higher early fat and enteral feed intakes are associated with improved outcome in girls, but not boys. Future research should determine sex-specific neonatal nutritional requirements.

Outcomes After Prehospital Endotracheal Intubation in Suburban/Rural Pediatric Trauma.

BACKGROUND: Trauma is the leading cause of death in pediatric patients over 1 y of age. Controversy exists regarding prehospital airway management for these patients, with some studies suggesting that endotracheal intubation in the field or at a referring hospital is associated with increased mortality and complication rate. These studies were largely performed at urban centers, and it is unclear whether the results apply to suburban/rural networks with longer transport times and more stops at referring hospitals. The purpose of this study is to evaluate differential outcomes in pediatric trauma patients who underwent endotracheal intubation at the scene of injury, referring hospital, or pediatric trauma center in a predominantly rural/suburban setting. MATERIALS AND METHODS: A retrospective review was performed evaluating trauma patients age 18 y or younger at a single institution over 10 y (2004-2014). Patients were selected who underwent endotracheal intubation and were classified based on location of intubation (scene, referring hospital, or trauma center). Fischer's exact test and t-tests were performed for comparison. Univariate and multivariate regression analyses were performed. RESULTS: 288 patients were identified. 155 (53.8%) were intubated at the scene of injury, 55 (19.1%) at a referring hospital, and 72 (25%) at the trauma center. Overall mortality was 21.9%, which was highest in the scene intubation group (29.7%) compared with the referring hospital (20%) and trauma center (5.6%) groups (P < 0.01). Patients intubated at the scene had higher Injury Severity Scores and lower Glasgow Coma Scale scores (P < 0.01). Duration of intubation was lowest in the trauma center group (P < 0.01). Complication rate was highest in the referring hospital group (P < 0.05). Multivariate analysis revealed that age, injury severity, and neurologic status were the key drivers of mortality rather than location of intubation. CONCLUSIONS: Mortality and duration of intubation were lowest in trauma patients intubated at a pediatric trauma center. However, location of intubation was not a significant independent predictor of mortality or complications on multivariate analysis, suggesting that age, injury severity, and neurologic status are the main indicators of prognosis in severe pediatric trauma.

Implementing Survey-Based Changes and Analyzing Usage in an Online Curriculum for Surgical Interns.

BACKGROUND: To improve the online curriculum at the authors' program, study habits and learning resources of surgical interns were evaluated. Based on the results, changes were implemented to align with their teaching conferences. We sought to determine utilization and satisfaction with the new materials. METHODS: At the end of the 2017 academic year, surgical interns at a single institution voluntarily responded to an Institutional Review Board-approved survey regarding new and established learning material use and study habits. Responses were deidentified. Descriptive statistics were performed on demographics. Likert responses underwent Mann-Whitney analysis (α = 0.05). RESULTS: The response rate was 52.9% (n = 9). The internet was the most-used resource (P < 0.05). All respondents used the internet to varying degrees. Textbooks and the internet were always used by 22.2%. 33.3% never used textbooks to study. There was a statistically significant increase in internet access but not with other materials (P < 0.05). Regarding new material organized from the pilot, none was consistently accessed. 55.6% sometimes used new weekly reading links associated with a question bank. 66.7% were somewhat satisfied with these links. 44.4% were somewhat satisfied with new video links, organized in parallel with This Week in Surgical Council on Resident Education. Limited sample size did not allow for meaningful statistical analysis of material use with American Board of Surgery In-Training Examination scores. CONCLUSIONS: Overall, materials organized based on pilot study feedback were not widely used, and satisfaction was limited. The statistically significant increase in use of internet resources warrants attention. Focusing changes in future curricular design may help create a more effective learning environment.

Associations Between National Board Exam Performance and Residency Program Emphasis on Patient Safety and Interprofessional Teamwork.

OBJECTIVE: Several aspects of medical training may contribute to the ultimate goal of producing excellent physicians whose patients will have the best possible outcomes. However, the relative importance of education, evaluation and feedback, duty hours, practice structure, and program culture in achieving this goal is unclear. This study assessed associations among in-training exam performance, Accreditation Council for Graduate Medical Education (ACGME) Resident Survey responses, and American Board of Medical Specialties (ABMS) national board exam performance. METHODS: Residency training programs at a university teaching hospital were classified as having 5-year first-time ABMS pass rates above (n=12) or below (n=3) the national average for their specialty. These groups were compared by ACGME Resident Survey data and in-training exam performance. RESULTS: Surveys were collected from 484/543 eligible residents (89%), including 177 surveys from programs with below-average board pass rates and 307 surveys from programs with aboveaverage board pass rates. In-training exam performance was similar between groups. Aboveaverage programs had stronger agreement with statements that their culture reinforced patient safety (4.72 vs. 4.30, p=0.006) and that information was not lost during transitions of care (4.14 vs. 3.63, p=0.001). Although the occurrence of interprofessional teamwork was similar between groups, above-average programs had stronger agreement with the statement that interprofessional teamwork was effective (4.60 vs. 4.17, p=0.003). CONCLUSION: Residency programs emphasizing patient safety and effective interprofessional teamwork had above-average first-time national board pass rates.

Evaluating the Impact of a Clinical Decision Support Tool to Reduce Chronic Opioid Dose and Decrease Risk Classification in a Veteran Population.

BACKGROUND: Chronic opioid therapy-clinical reminder (COT-CR) is a decision support tool to prompt providers to carefully assess patients prescribed chronic opioids. This tool was developed to address inappropriate opioid prescribing. OBJECTIVE: To determine COT-CR's impact on reducing morphine equivalent monthly dose (MEMD) and risk index for overdose or serious prescription opioid-induced respiratory depression (RIOSORD) values in veterans receiving chronic opioids. METHODS: This retrospective cohort review matched patients with a complete COT-CR to patients with an incomplete COT-CR using propensity scores. In the primary aim, an interrupted time series design evaluated for changes in MEMD 12 months before and 6 months after the index date. The index date was the first pain or primary care provider visit post COT-CR installation. In the secondary aims, a retrospective cohort design was used to evaluate the changes in RIOSORD index score and risk class 6 months after the index date. RESULTS: After matching, 3801 patients were included in the complete and incomplete COT-CR groups, respectively. Greater average reduction in MEMD (-11.6 MEMD; 95% CI = -0.97 to -22.25 MEMD; P = 0.032) and RIOSORD index score (-0.53 RIOSORD index score; 95% CI = -1.00, -0.05 RIOSORD index score; P = 0.030) was observed in patients with a complete COT-CR compared to patients with an incomplete COT-CR. Differences in RIOSORD risk class were insignificant. CONCLUSION: Completing the COT-CR was associated with reduced MEMD and RIOSORD values. This suggests that active monitoring can change prescribing patterns, thereby, reducing the overall risk of opioid overdose in at-risk veterans.

Inguinal hernias in premature neonates: exploring optimal timing for repair.

PURPOSE: Inguinal hernias have been reported in as many as 10-30% premature neonates, making inguinal herniorrhaphy (IHR) one of the most commonly performed surgical procedures. The timing of surgery remains controversial. The purpose of this report is to compare outcomes of IHR while in the NICU (inpatient) versus repair following discharge (outpatient) to determine optimal timing. METHODS: Premature neonates having undergone IHR over a 5-year period were identified and a retrospective case cohort analysis was performed. RESULTS: 263 patients underwent IHR during the 5-year study period with 115 (43.7%) having surgical repair inpatient (IP; prior to discharge) and 148 having outpatient herniorrhaphy (OP). Patients with IHR performed IP had significantly lower birth weight (p < 0.001), gestational age (p < 0.001), longer duration of surgery (p = 0.01) and were more likely to have post-operative ventilator dependence following repair; however, there were no differences in the rate of recurrence (p = 0.44) and incarceration (p = 0.45). CONCLUSION: Our study demonstrated no significant differences in the rates of incarceration or recurrence, following in- or out-patient IHR. These findings suggest that IHR can potentially be offered as an outpatient procedure following hospital discharge in appropriate patients. The optimal timing of IHR in premature infants remains elusive and will likely require additional multicenter investigation.

Improving person-centered mobility care in nursing homes: a feasibility study.

Person-centered care is often equated with quality nursing home care. At the same time, quality mobility care contributes to residents' independence and quality of life. Realist evaluation and mixed methods were employed to evaluate the feasibility of a multi-faceted training intervention focused on person-centered mobility care. Staff and ambulatory residents of a ninety bed Australian nursing home with 3 units--one dementia-specific--participated. The intervention consisted of training sessions, weekly mobility care huddles and reflective practice sessions with individual staff. This study demonstrated the feasibility of an intervention aiming to improve person-centered mobility care in nursing homes; it was practical and well accepted. Study methods and outcome measures were suitable. Outcome measures demonstrated capacity to determine the effectiveness of the intervention in a larger randomized controlled trial. Focus groups provided insights regarding the context and mechanisms of change. Future research is recommended to evaluate intervention effectiveness and sustainability.

Targeting mitochondrial 18 kDa translocator protein (TSPO) regulates macrophage cholesterol efflux and lipid phenotype.

The aim of the present study was to establish mitochondrial cholesterol trafficking 18 kDa translocator protein (TSPO) as a potential therapeutic target, capable of increasing macrophage cholesterol efflux to (apo)lipoprotein acceptors. Expression and activity of TSPO in human (THP-1) macrophages were manipulated genetically and by the use of selective TSPO ligands. Cellular responses were analysed by quantitative PCR (Q-PCR), immunoblotting and radiolabelling, including [3H]cholesterol efflux to (apo)lipoprotein A-I (apoA-I), high-density lipoprotein (HDL) and human serum. Induction of macrophage cholesterol deposition by acetylated low-density lipoprotein (AcLDL) increased expression of TSPO mRNA and protein, reflecting findings in human carotid atherosclerosis. Transient overexpression of TSPO enhanced efflux (E%) of [3H]cholesterol to apoA-I, HDL and human serum compared with empty vector (EV) controls, whereas gene knockdown of TSPO achieved the converse. Ligation of TSPO (using PK11195, FGIN-1-27 and flunitrazepam) triggered increases in [3H]cholesterol efflux, an effect that was amplified in TSPO-overexpressing macrophages. Overexpression of TSPO induced the expression of genes [PPARA (peroxisome-proliferator-activated receptor α), NR1H3 (nuclear receptor 1H3/liver X receptor α), ABCA1 (ATP-binding cassette A1), ABCG4 (ATP-binding cassette G4) and APOE (apolipoprotein E)] and proteins (ABCA1 and PPARα) involved in cholesterol efflux, reduced macrophage neutral lipid mass and lipogenesis and limited cholesterol esterification following exposure to AcLDL. Thus, targeting TSPO reduces macrophage lipid content and prevents macrophage foam cell formation, via enhanced cholesterol efflux to (apo)lipoprotein acceptors.

The emergent relevance of care staff decision-making and situation awareness to mobility care in nursing homes: an ethnographic study.

AIM: To explore mobility care as provided by care staff in nursing homes. BACKGROUND: Care staff regularly assist residents with their mobility. Nurses are increasingly reliant on such staff to provide safe and quality mobility care. However, the nature of care staff decision-making when providing assistance has not been fully addressed in the literature. DESIGN: A focused ethnography. METHOD: The study was conducted in four nursing homes in Melbourne, Australia. Non-participant observations of residents and staff in 2011. Focus groups with 18 nurses, care and lifestyle staff were conducted at three facilities in 2012. Thematic analysis was employed for focus groups and content analysis for observation data. Cognitive Continuum Theory and the notion of 'situation awareness' assisted data interpretation. FINDINGS: Decision-making during mobility care emerged as a major theme. Using Cognitive Continuum Theory as a guide, nursing home staff's decision-making was described as ranging from system-aided, through resident- and peer-aided, to reflective and intuitive. Staff seemed aware of the need for resident-aided decision-making consistent with person-centred care. Habitual mobility care based on shared mental models occurred. It was noted that levels of situation awareness may vary among staff. CONCLUSION: Care staff may benefit from support via collaborative and reflective practice to develop decision-making skills, situation awareness and person-centred mobility care. Further research is required to explore the connection between staff's skills in mobility care and their decision-making competence as well as how these factors link to quality mobility care.

Beyond the Neonate: A Delayed Presentation of Congenital Diaphragmatic Hernia in a 17-Year-Old.

Congenital diaphragmatic hernia (CDH) is a rare anomaly resulting from incomplete closure of pleuroperitoneal canals during fetal development, often presenting with acute respiratory distress in neonates. This case report highlights a 17-year-old female with recurrent episodes of acute left upper quadrant (LUQ) pain and no history of trauma or dietary change. A computerized tomography (CT) scan taken during her second presentation to the emergency department led to a diagnosis of left-sided CDH. She later had a successful laparoscopic diaphragmatic repair surgery and has remained symptom-free for over a year. Late-presenting CDH indicates a rare subset of cases diagnosed after one month of age. Late presentations comprise 5-25% of cases and become increasingly rare with age. Unlike neonatal CDH, which is associated with several comorbidities, late presentations often manifest as a standalone anomaly. When the correct diagnosis is made, uncomplicated surgical repair yields excellent long-term outcomes. However, delayed and incorrect diagnoses can result in serious morbidity. Late-presenting CDH has diverse clinical presentations and can elude diagnostic imaging. As a result, there is a need for heightened clinical suspicion. This report aims to enhance awareness of late-presenting CDH and explore challenges to prompt, accurate diagnosis. Ultimately, this study implores clinicians to consider this condition in patients with unexplained respiratory or gastrointestinal symptoms.

Mitochondrial (dys)function and regulation of macrophage cholesterol efflux.

Cholesterol trafficking from the outer to the cholesterol-poor inner mitochondrial membrane requires energized, polarized and actively respiring mitochondria, mediated by a highly regulated multimeric (140-200 kDa) protein complex comprising StAR (steroidogenic acute regulatory protein), mitochondrial TSPO (translocator protein), VDAC (voltage-dependent anion channel), ANT (adenine nucleotide transporter) and associated regulatory proteins. Mitochondrial cholesterol transport is rate-limiting in the CYP27A1 (sterol 27-hydroxylase)-dependent generation of oxysterol ligands for LXR (liver X receptor) transcription factors that regulate the expression of genes encoding proteins in the cholesterol efflux pathway, such as ABC transporters (ATP-binding cassette transporters) ABCA1 and ABCG1. These transporters transfer cholesterol and/or phospholipids across the plasma membrane to (apo)lipoprotein acceptors, generating nascent HDLs (high-density lipoproteins), which can safely transport excess cholesterol through the bloodstream to the liver for excretion in bile. Utilizing information from steroidogenic tissues, we propose that perturbations in mitochondrial function may reduce the efficiency of the cholesterol efflux pathway, favouring accumulation of cholesteryl ester 'foam cells' and allowing the toxic accumulation of free cholesterol at the interface between the endoplasmic reticulum and the mitochondrial membrane. In turn, this will trigger opening of the permeability transition pore, allowing unregulated production of oxysterols via CYP27A1, allowing the accumulation of esterified forms of this oxysterol within human atherosclerotic lesions. Defective cholesterol efflux also induces endoplasmic reticulum stress, proteasomal degradation of ABCA1 and Fas-dependent apoptosis, replicating findings in macrophages in advanced atherosclerotic lesions. Small molecules targeted to mitochondria, capable of sustaining mitochondrial function or improving cholesterol trafficking may aid cholesterol efflux from macrophage 'foam' cells, regressing and stabilizing the atherosclerotic plaque.

A qualitative descriptive study of effective leadership and leadership development strategies used by nurse leaders in European island countries.

AIM: Nurse leaders influence workplace culture; however, little is known about ethnic cultural influences on nurse leader development. This research aims to identify personal strategies promoting effective leadership by nurse leaders from European small island countries. DESIGN: Descriptive qualitative study. METHODS: In 2017, nineteen semi-structured interviews with nurse leaders from England, Greece, Republic of Ireland and Malta explored leadership journeys, strategies employed to support their growth and development, and how cultural identity played a role. Transcripts were analysed using reflexive thematic analysis. RESULTS: Four main themes and 12 subthemes captured the strategies and approaches of the nurse leaders: (1) Influences, (2) Communication, (3) Process and (4) Relationships. These findings reflect and validate the five transformational leadership practices of the Exemplary Leadership Model. While cultural island identity was discussed, there was a shared cultural identity within the role of "nurse leader" that spanned all islands. PATIENT OR PUBLIC CONTRIBUTIONS: Nineteen nurse leaders contributed to this study.

Does Preterm Status Hinder the Timely Diagnosis of Intestinal Atresia?

Intestinal atresia is one of the most common causes of bowel obstruction in newborns. Unfortunately, this diagnosis is often missed or delayed in extremely preterm infants because of complications of prematurity including feeding intolerance and necrotizing enterocolitis. Here we report 2 cases of jejunoileal atresia in extremely preterm infants who were diagnosed beyond 30 days of age. Case 1 had jejunoileal atresia type IIIa, whereas case 2 had type IV jejunoileal atresia complicated by short bowel syndrome. Ideally, intestinal atresia should be diagnosed as early as possible in a patient's hospital course to attain full enteral feedings earlier and avoid prolonged hospitalization. Planned surgical intervention prior to the development of sepsis or bowel perforation is associated with better outcomes. Ultimately, this report serves as a reminder to physicians that intestinal atresia remains an important differential for infants, including preterm infants, with feeding intolerance in the first days to weeks of age.

Structural evaluation of child physical abuse in trauma: Social determinants of health at the population level.

PURPOSE: Child physical abuse (CPA) is closely linked to social factors like insurance status with limited evaluation at a structural population-level. This study evaluates the role of social determinants of health within the built environment on CPA. METHODS: A single-institution retrospective review of pediatric trauma patients was conducted between January 2016 and December 2020. Patient address was geocoded to the census-tract level. Socioeconomic metrics, including poverty rate, supermarket access and Social Vulnerability Index (SVI) were estimated from the Food Access Research Atlas. Univariate and multivariable regression analyses were conducted to compare demographics and outcomes. RESULTS: Of 3,540 patients, 317 (9.0%) had concern for physical abuse reported in the registry. CPA patients were younger (7.5 vs 9.6 years, p<0.0001) and more often Black (37.0%, N = 117 vs 23.5%, N = 753; p<0.0001). CPA had higher injury severity scores (ISS) (7.9 vs 5.8, p<0.0001) and longer length of stay (5.3 vs 2.9 days, p<0.0001). CPA had higher Medicaid (73.0%, N = 232 vs 53.8%, N = 1748, p<0.0001) and SVI (0.65 vs 0.59, p<0.0001) with lower median income ($52,100 vs $56,100, p<0.0001) and more low-food access tracts (59.6% vs 53.6%, p = 0.06). Combined low-income and low-food access populations showed widened disparities (40.0% vs 28.9%, p = 0.0002). On multivariate analysis, CPA was associated with poverty (OR 2.3, 95% CI [0.979, 3.60], p = 0.0006), low-access Black share (OR 3.3, 95% CI [1.18, 5.47], p = 0.002) and urban designation (OR 1.5, 95% CI [1.13, 1.87], p = 0.004). CONCLUSION: The built-environment and population-level social determinants of health are related to child physical abuse and should influence advocacy and prevention. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective.
