The Jarring Reality: Adolescent and Pediatric Gunshot Trauma on the Rise in a Major Urban Institution.

Firearms are the leading cause of death in the pediatric population, and the incidence of firearm injury is on the rise in the United States. The purpose of this study was to examine the incidence of pediatric gunshot wounds (GSWs) in New Orleans from 2012 to 2023 and evaluate factors that contribute to mortality. A retrospective analysis of pediatric GSWs was conducted using the trauma database at a Level I trauma center in New Orleans, Louisiana. All patients aged 0 to 18 years with a GSW between January 1, 2012, and January 1, 2023, were evaluated. Demographic data, Injury Severity Score (ISS), hospital length of stay (LOS), discharge disposition, intent of injury, mortality, firearm type, orthopaedic injuries, and related surgical procedures were extracted from the database. Linear regression was used to assess the trend of GSWs over time, and logistic regression was used to identify variables that predicted mortality. Statistical significance was defined as α = 0.05. Geographic information system (GIS) mapping was conducted using the ZIP code location of injury to identify geographic areas with the greatest number of GSWs. A significant increasing trend was observed in the number of pediatric GSWs when adjusted for changes in population (P = 0.014), and the number of GSWs increased 43.2% over the duration of the study. Higher ISS, shorter length of stay, and self-inflicted intent of injury were notable predictors of mortality. Three hundred fifty-four patients (31.4%) had at least one orthopaedic injury, and of the survivors, 365 patients (35.6%) required at least one surgical procedure in the operating room during their admission. The number of GSWs in the pediatric population in New Orleans presenting at a large level 1 trauma center demonstrated a statistically significant increasing trend over the past 11 years. ISS and self-inflicted intent were predictive of mortality within this pediatric patient population.

Left atrial strain analysis in the realm of pediatric cardiology: Advantages and implications.

Left atrial (LA) strain analysis has emerged as a noninvasive technique for assessing LA function and early detection of myocardial deformation. Recently, its application has also shown promise in the pediatric population, spanning diverse cardiac conditions that demand accurate and sensitive diagnostic measures. This research article endeavors to explore the role of LA strain parameters and contribute to the growing body of knowledge in pediatric cardiology, paving the way for more effective and tailored approaches to patient care. A comprehensive literature review was conducted to gather evidence from studies using echocardiographic strain imaging techniques across pediatric populations. LA strain parameters exhibited greater sensitivity than conventional atrial function indicators, with early detection of diastolic dysfunction and LA remodeling in pediatric cardiomyopathy, children with multisystem inflammatory syndrome, rheumatic heart disease, as well as childhood renal insufficiency and obesity offering prognostic relevance as potential markers in these pediatric subpopulations. However, there remains a paucity of evidence concerning pediatric mitral valve pathology, justifying further exploration. LA strain analysis carries crucial clinical and prognostic implications in pediatric cardiac conditions, with reliable accuracy and sensitivity to early functional changes.

Diagnosis and treatment of dyslipidemia in children and adolescents

Background: Atherosclerotic cardiovascular disease is a major cause of morbidity and mortality worldwide, including in South Korea. Dyslipidemia is an independent risk factor for the development of atherosclerotic cardiovascular diseases. There is strong evidence that atherosclerosis begins early in life and that elevated lipid levels in childhood predict elevated lipid levels into adulthood.Current Concepts: A universal approach for cholesterol screening in all children is recommended. Lipid profiles should be studied for all children aged 9 to 11 years and then for those aged 17 to 21 years, as cholesterol levels may vary after puberty. The non-fasting lipid profile can be as useful in detecting severe genetic dyslipidemias as the fasting lipid profile and thus can be used as a first-line screening in children. The initial treatment for dyslipidemia in a child always begins with a 6-month trial of lifestyle modifications, such as improvements in dietary and physical activity patterns. Statins are as effective in children as in adults and can lower low-density lipoprotein cholesterol levels by up to 50%. Therefore, they are considered first-line therapy for children who meet the criteria for pharmacological therapy.Discussion and Conclusion: Statins and non-statin lipid-lowering agents can lower cholesterol levels with minimal adverse effects in children and adolescents with hypercholesterolemia. However, limited data is currently available on the long-term safety and efficacy of lipid-lowering agents in the pediatric population. Furthermore, non-statin lipid-lowering agents are used far less frequently in children. Therefore, further long-term safety and efficacy studies on lipid-lowering agents in pediatric populations and clinical trials with non-statin lipid-lowering agents are required.

Exploring gender identity in paediatric dermatology.

This ethical dilemma explores gender identity within the paediatric population. It also considers the fundamental principles of consent for minors, with non-maleficence as an overarching framework to safeguard children.

Safety and effectiveness of evicel®fibrin sealant as an adjunct to sutured dural repair in children undergoing cranial neurosurgery.

Cerebrospinal fluid (CSF) leakage is a challenging complication of intradural cranial surgery, and children are particularly at risk. The use of dural sealants confers protection in adults, but pediatric studies are scarce. We evaluated the safety and efficacy of Evicel® fibrin sealant as an adjunct to primary dural suturing in children undergoing cranial surgery. A multicenter trial prospectively enrolled pediatric subjects (< 18years) undergoing cranial neurosurgery who, upon completion of primary sutured dural repair, experienced CSF leakage. As agreed by the EMA Evicel® Pediatric Investigation Plan, 40 subjects were intra-operatively randomized 2:1 to Evicel® or additional sutures ('Sutures'). Data analysis was descriptive. The efficacy endpoint was treatment success rate, with success defined as intra-operative watertight closure after provocative Valsalva maneuver (primary endpoint). Safety endpoints were postoperative CSF leakage (incisional CSF leakage, pseudomeningocele or both) and surgical site complications (secondary endpoints). Forty subjects (0.6-17years) were randomized to Evicel® (N = 25) or Sutures (N = 15) (intention-to-treat). Intracranial tumor was the most common indication and procedures were mostly supratentorial craniotomies. Success rates were 92.0% for Evicel® and 33.3% for Sutures, with a 2.76 estimated ratio of success rates (Farrington-Manning 95% CI [1.53, 6.16]). Sensitivity analyses in per-protocol and safety sets showed similar results. Despite a higher rescue treatment rate, the frequencies of postoperative CSF leakage and wound complications were higher for Sutures than for Evicel®. This small-scale prospective study shows Evicel® treatment to be safe and effective as an adjunct to primary sutured dura mater closure in a pediatric population. Compared to additional sutures, Evicel® was associated with reduced postoperative CSF leakage and surgical site complications. (Trial registration: The trial was registered as NCT02309645 and EudraCT 2013-003558-26).

What Explains Inequalities in Telehealth Utilization Among North Carolina Medicaid Beneficiaries?

Background: Increased availability of telehealth can improve access to health care. However, there is evidence of persistent disparities in telehealth usage, as well as among people from minoritized racial and ethnic groups and rural residents. The objective of our work was to explore the degree to which disparities in telehealth use for behavioral health (BH) and musculoskeletal (MSK) related services during the COVID-19 pandemic are explained by observed beneficiary- and area-level characteristics. Methods: Using North Carolina Medicaid claims data of Medicaid beneficiaries with BH or MSK conditions, we apply nonlinear regression-based decomposition analysis-based models developed by Kitagawa, Oaxaca, and Blinder to determine which observed variables are associated with racial, ethnic, and rural inequalities in telehealth usage. Results: In the BH cohort, we found statistically significant differences in telehealth usage by race in the adult population, and by race, Hispanic ethnicity, and rurality in the pediatric population. In the MSK cohort, we found significant inequities by Hispanic ethnicity and rurality among adults, and by race and rurality among children. Inequalities in telehealth use between groups were small, ranging from 0.7 percentage points between urban and rural adults with MSK conditions to 3.8 percentage points between white adults and people of color among those with BH conditions. Overall, we found that racial and ethnic inequalities in telehealth use are not well explained by the observed variables in our data. Rural disparities in telehealth use are better explained by observed variables, particularly area-level broadband internet use. Conclusions: For inequalities between rural and urban residents, our analysis provides observational evidence that infrastructure such as broadband internet access is an important driver of differences in telehealth use. For racial and ethnic inequalities, the pathways may be more complex and difficult to measure, particularly when relying on administrative data sources in place of more detailed data on individual-level socioeconomic factors.

Strategic HIV Case Findings among Infants at Different Entry Points of Health Facilities in Cameroon: Optimizing the Elimination of Mother-To-Child Transmission in Low- and- Middle-Income Countries

Background: HIV case finding is an essential component for ending AIDS, but there is limited evidence on the effectiveness of such a strategy in the pediatric population. We sought to determine HIV positivity rates among children according to entry points in Cameroon. Methods: A facility-based survey was conducted from January 2015 to December 2019 among mother–child couples at various entry points of health facilities in six regions of Cameroon. A questionnaire was administered to parents/guardians. Children were tested by polymerase chain reaction (PCR). Positivity rates were compared between entry points. Associations were quantified using the unadjusted positivity ratio (PR) for univariate analyses and the adjusted positivity ratio (aPR) for multiple Poisson regression analyses with 95% confidence intervals (CIs). p-values &lt; 0.05 were considered significant. Results: Overall, 24,097 children were enrolled. Among them, 75.91% were tested through the HIV prevention of mother-to-child transmission (PMTCT) program, followed by outpatient (13.27%) and immunization (6.27%) services. In total, PMTCT, immunization, and outpatient services accounted for 95.39% of children. The overall positivity was 5.71%, with significant differences (p &lt; 0.001) between entry points. Univariate analysis showed that inpatient service (PR = 1.45; 95% CI: [1.08, 1.94]; p = 0.014), infant welfare (PR = 0.43; 95% CI: [0.28, 0.66]; p &lt; 0.001), immunization (PR = 0.56; 95% CI: [0.45, 0.70]; p &lt; 0.001), and PMTCT (PR = 0.41; 95% CI: [0.37, 0.46]; p &lt; 0.001) were associated with HIV transmission. After adjusting for other covariates, only PMTCT was associated with transmission (aPR = 0.66; 95% CI: [0.51, 0.86]; p = 0.002). Conclusions: While PMTCT accounts for most tested children, high HIV positivity rates were found among children presenting at inpatient, nutrition, and outpatient services and HIV care units. Thus, systematic HIV testing should be proposed for all sick children presenting at the hospital who have escaped the PMTCT cascade.

Epidemiological Characteristics of Shiga Toxin-Producing Escherichia coli Responsible for Infections in the Polish Pediatric Population.

Shiga toxin-producing Escherichia coli (STEC) are zoonotic pathogens causing hemorrhagic colitis and hemolytic uremic syndrome (HUS) in children and the elderly. Stool samples were collected from 180 children hospitalized in five pediatric centers in Poland in 2018-2022. Direct stx1/stx2 gene detection by PCR in feces and E. coli isolates was performed. Antibiotic susceptibility was tested according to EUCAST v.12. Randomly selected isolates were serotyped with O157 antiserum and genotyped by pulsed-field gel electrophoresis (PFGE). A total of 44 E. coli isolates were confirmed as STEC by PCR. Among them, 84.4% were positive for stx2, and equally 6,8% for only stx1 and both stx1 and stx2 genes. The stx1 gene was also found in one Citrobacter freundii isolate. E. coli serotype O157 was present in 97.6% of the isolates. STEC infections most often occurred between June-October with a peak in July and August (51%). The highest, 77.8% of STEC isolates were found in the 1-5 years old group. No extended-spectrum β-lactamases (ESBL) were found. Resistance only to amoxicillin/clavulanic acid (24.4%), piperacillin/tazobactam (3%), cefotaxime (6%), gentamicin (6%), ciprofloxacin (3%), azithromycin (3%), trimethoprim/sulfamethoxazole (24,2%) was detected. PFGE analysis showed 18 PFGE types with no clonal distribution. Eight isolates with A, B, and C PFGE types showed genetic relatedness in the type with no detection of transmission way of distribution. STEC strains pose a serious threat to human health, therefore demographic and epidemiological characteristics are crucial for their surveillance.

Pediatric Takotsubo cardiomyopathy: a review and insights from a national multicentric registry

Abstract Funding Acknowledgements None. Background Takotsubo syndrome (TTS) in the pediatric population is an infrequent but relevant cause of morbidity and mortality, with limited studies addressing its clinical course and prognosis. Objectives We aimed to analyze the clinical features and prognosis of pediatric TTS in a nation-wide multicenter registry and considering the published literature. Methods we included a total of 54 patients from 4 different hospitals in Spain, as well as pediatric TTS patients from the published literature. Comparisons between groups were performed in order to assess for statistically and clinically relevant prognostic differences between pediatric and adult population features. Results Comparison between the RETAKO general population is detailed in Table 1. Pediatric patients with TTS had a median age of 11 years (IQR = 4-14). When compared to the RETAKO general population, they were more often male (51.9% vs 23.3%, p&amp;lt;0.001), and displayed a higher prevalence of secondary forms (90.7% vs 35.6% in adults, p&amp;lt;0.001). Regarding race, 11 cases (20.4%) were from Asia and 42 (77.8%) were Caucasian; whereas in RETAKO 1420 (94.9%) were Caucasians, with under 5 cases (&amp;lt;0.1%) being Asian. Pediatric patients presented less commonly with angina (11.1% vs 64.1%, p&amp;lt;0.001) or dyspnea (30% vs 41.7%, p&amp;lt;0.001), compared to the general RETAKO cohort. Nevertheless, pediatric patients with TTS exhibited a higher Killip status on admission (Killip IV 74.1% vs 10.5%, p&amp;lt;0.001), and higher needs of vasoactive and mechanical ventilatory support during hospitalization. Regarding complementary exams, pediatric patients presented with lower LVEF on admission (30.5+10.4 vs 36.9+16.9, p = 0.014) together with greater prevalence of atypical (basal or midventricular) TTS patterns on echocardiography (30.2% vs 15.8%, p = 0.006). Additionally, there were significantly less ST-segment alterations in the pediatric population (either ST-segment elevation or depression), without differences on T wave inversion in the admission ECG. During follow-up, all-cause deaths (11.1% vs 12,5%, p = 0.761) and TTS recurrences (3.8% vs 3,8%, p = 0.863) were similar between groups. Conclusions TTS in the pediatric population presents a distinctive clinical profile, with higher prevalence of atypical symptoms and physical triggers; as well as higher rates of cardiogenic shock on admission and similar mortality and recurrence rates than those of the adult population. This study provides valuable insights into understanding pediatric TTS and underscored the necessity for further research in this age group.Table 1

Nursing-sensitive outcomes for the provision of pain management in pediatric populations with intellectual disabilities: a scoping review protocol.

This aim of this review is to identify and map nursing-sensitive outcomes for the provision of pain management in pediatric populations with intellectual disabilities that are currently reported in the literature. The experience of pain is highly individualized and subjective, with physiological, biochemical, and psychological differences contributing to pain perception. Pediatric populations with intellectual disabilities are at increased risk of ubiquitous pain exposure. Pain management effectiveness can be determined through the measurement of nursing-sensitive outcomes, which have not been mapped in the context of pediatric populations with intellectual disabilities. Quantitative, qualitative, mixed methods, and gray literature discussing nursing pain management in pediatric populations with intellectual disabilities will be included. No date limits will be applied. Only studies published in English will be considered. This review will be guided by the JBI methodology for scoping reviews. The search strategy will aim to locate published and unpublished literature using the databases CINAHL (EBSCOhost), MEDLINE (Ovid), Embase (Ovid), Scopus, PsycINFO (ProQuest), LILACS, SciELO, and ProQuest Dissertations and Theses Global. Titles and abstracts, and then full-text studies, will be selected and reviewed by 2 independent researchers against the inclusion criteria. Content analysis using the NNQR-C, C-HOBIC, NDNQI, and Donabedian model frameworks will be used for data extraction and organization, accompanied by charted results and narrative summaries, as appropriate.

T2-FLAIR Mismatch: An Imaging Biomarker for Children's MYB/MYBL1-Altered Diffuse Astrocytoma or Angiocentric Glioma.

T2-FLAIR mismatch is a highly specific imaging biomarker of IDH-mutant diffuse astrocytoma in adults. It has however also been described in MYB/MYBL1-altered low grade tumors. Our aim was to assess the diagnostic power of the T2-FLAIR mismatch in IDH-mutant astrocytoma and MYB/MYBL1-altered low-grade tumors in children and correlate this mismatch with histology. We evaluated MR imaging examinations of all pediatric patients, performed at the Princess Máxima Center for Pediatric Oncology and the University Medical Center Utrecht between January 2012 and January 2023, with the histomolecular diagnosis of IDH-mutant astrocytoma, diffuse astrocytoma MYB/MYBL1-altered, or angiocentric glioma, and the presence of T2-FLAIR mismatch was assessed. Histologically, the presence of microcysts in the tumor (a phenomenon suggested to be correlated with T2-FLAIR mismatch in IDH-mutant astrocytomas in adults) was evaluated. Nineteen pediatric patients were diagnosed with either IDH-mutant astrocytoma (n = 8) or MYB/MYBL1-altered tumor (n = 11: diffuse astrocytoma, MYB- or MYBL1-altered n = 8; or angiocentric glioma n = 3). T2-FLAIR mismatch was present in 11 patients, 3 (38%) in the IDH-mutant group and 8 (73%) in the MYB/MYBL1 group. No correlation was found between T2-FLAIR mismatch and the presence of microcysts or an enlarged intercellular space in either IDH-mutant astrocytoma (P = .38 and P = .56, respectively) or MYB/MYBL1-altered tumors (P = .36 and P = .90, respectively). In our pediatric population, T2-FLAIR mismatch was more often found in MYB/MYBL1-altered tumors than in IDH-mutant astrocytomas. In contrast to what has been reported for IDH-mutant astrocytomas in adults, no correlation was found with microcystic changes in the tumor tissue. This finding challenges the hypothesis that such microcystic changes and/or enlarged intercellular spaces in the tissue of these tumors are an important part of explaining the occurrence of the T2-FLAIR mismatch.

Pediatric Facial Fractures: Demographics, Injury Patterns, and Associated Injuries in 3334 Patients.

Pediatric craniofacial fractures are fundamentally distinct from their adult counterparts because of unique injury patterns and effects on future growth. Understanding patterns and injury context informs management and risk mitigation. Previous studies include only inpatients, operative patients, or are specialty-specific. In contrast, our study presents a comprehensive assessment of all pediatric facial fracture patients seen at a single institution. Patients under 18 years old who were evaluated for facial fractures at a level I pediatric trauma center between 2006 and 2021 were reviewed. Subanalysis was performed for groups defined by age. Variables studied included demographics, etiology, fracture pattern, associated injuries, management, and outcomes. Three thousand thirty-four patients were included. Mean age at presentation was 11.5 to 4.9 years. The majority were Caucasian (82.6%) and male (68.4%). Sports were the leading cause of injury in older patients (42.2% of patients over 12y), compared with activities of daily living in patients under 6 years (45.5%). Thirty-two percent of patients were hospitalized, 6.0% required ICU care, and 48.4% required surgery. Frequency of ICU admission decreased with age (P<0.001), whereas operative intervention increased with age (P<0.001). Zygomaticomaxillary complex (P=0.002) and nasal fractures (P<0.001) were common in older patients, whereas younger patients experienced more skull (P<0.001) and orbital fractures (P<0.001). The most associated injuries were soft tissue (55.7%) and neurologic (23.6%). This large-scale study provides updated characterization of craniofacial fractures in the pediatric population, providing a necessary framework for future studies on outcomes assessments and preventative care.

BCG activation of trained immunity is associated with induction of cross reactive COVID-19 antibodies in a BCG vaccinated population

Background Pakistan is endemic to a diverse set of parasitic, mycobacterial and viral diseases. The recognition of BCG Trained Immunity (TI) led us to postulate that the continued presence of BCG-TI may play a protective role, previously reported for both infectious and noninfectious conditions. Most of the previous studies have addressed the issue of BCG-TI in the paediatric populations. This study addressed the key issue of maintenance of BCG-TI in a wider age range (adolescent and adults) to identify the strength and quality of the immune responses. Objective To assess the BCG-induced recall responses in healthy individuals by cytokines secreted from the TI network and its potential role in providing cross-protection against COVID-19 and other viral infections. Study design In this cross-sectional study, healthy young adults and adolescents (n = 20) were recruited from 16–40 years of age, with no prior history of TB treatment, autoimmune, or chronic inflammatory condition. Methods BCG-induced cytokine responses were assessed using prototypic markers for cells of the TI network [macrophages [M1 (TNFα, IFNγ), M2 (IL10)], NK (IL2), Gamma delta (γδ) T (IL17, IL4)] and SARS CoV2 IgG antibodies against RBD using short-term (12 hrs.) cultures assay. Results Significant differences were observed in the magnitude of recall responses to BCG with macrophage cytokines showing the highest mean levels of TNFα (9148 pg/ml) followed by IL10 (488 pg/ml) and IFNγ (355 pg/ml). The ratio of unstimulated vs.BCG-stimulated cytokines was 132 fold higher for TNFα, 40 fold fo r IL10, and 27 fold for IFNγ. Furthermore, SARS-CoV-2 antibodies were also detected in unstimulated plasma which showed cross reactivity with BCG. Conclusion The presence of cross reactive antibodies to SARS-CoV-2 and the relative ratio of pro- and anti-inflammatory cytokines secreted by activated TI cellular network may play a pivotal role in protection in the early stages of infection as observed during the COVID-19 pandemic in the younger age groups resulting in lower morbidity and mortality.

Prevalence and mortality of haemophagocytic lymphohistiocytosis in dengue fever: a systematic review and meta-analysis.

Haemophagocytic lymphohistiocytosis (HLH) is a rare complication of dengue fever with potentially life-threatening consequences and high mortality. Therefore, this study aims to investigate the prevalence, management and outcome of HLH in dengue fever. The major electronic databases, including PubMed, ScienceDirect and Ovid SP, were searched from inception until 31 January 2024 to identify relevant studies. Pooled prevalence and mortality were calculated using the random-effects generic inverse variance model with a 95% CI. All the statistical analysis was conducted using R programming. A total of nine studies with 157 patients with HLH, 576 patients with severe dengue and 5081 patients with dengue fever were included in this meta-analysis. The prevalence of HLH in severe dengue (22.1%, 95% CI 8.07 to 48.0%) was significantly higher than the prevalence in dengue fever (3.12%, 95% CI 0.37 to 21.9%). The prevalence of HLH in severe dengue was higher in the paediatric population (22.8%, 95% CI 3.9 to 68.4%) compared with the adult population (19.0%, 95% CI 3.0 to 63.9%). The overall mortality rate was 20.2% (95% CI 9.7 to 37.2%). The prevalence of dengue-associated HLH was low in patients with dengue fever but is significantly higher in patients with severe dengue and a high mortality rate.

Remimazolam for sedation and anesthesia in children: A scoping review.

Remimazolam, a novel intravenous benzodiazepine recently approved by both the European Medicines Agency and the Food and Drug Agency, shows considerable promise in clinical practice. Its pharmacodynamic profile closely resembles that of midazolam, while its pharmacokinetic properties are similar to those of remifentanil. While research in adult populations continues to accumulate, the pace of pediatric studies is not as significant. This scoping review aims to systematically examine published studies, clinical trials, observational research, case reports, and relevant literature to provide a comprehensive understanding of remimazolam in pediatric sedation and anesthesia. By synthesizing the gathered evidence, we aim to identify gaps in the literature, guide future research endeavors, and inform clinical practices. The review follows the guidelines outlined by the Preferred Reporting Items for Systematic Review and Meta-Analysis for Scoping Review. A thorough search strategy was implemented across prominent peer-reviewed databases, with focused efforts to identify relevant grey literature. All primary studies involving the use of remimazolam in pediatric populations were included in this review. Eighteen studies were included in this analysis, comprising 2 randomized controlled trials, 4 prospective cohort trials, 12 case reports, and 692 children in total. This scoping review highlights the increasing interest in using remimazolam as a sedative or anesthetic for children. Although initial evidence indicates its effectiveness and safety, more research is necessary to fill knowledge gaps, establish standard protocols, and optimize its use in pediatric anesthesia and sedation. Addressing these challenges will enable clinicians to improve the quality of care and outcomes for pediatric patients undergoing sedation and anesthesia.

Obesity as a Risk Factor for Adverse Outcomes After Pedestrian Trauma Accidents in the Pediatric Population.

The aim of the study is to determine whether overweight or obese children are at an increased risk for injury and adverse outcomes following pedestrian motor vehicle accidents. We performed a retrospective study of patients between the ages of 2 and 17 who were pedestrians injured in a collision with a motorized vehicle, presenting to a level 1 trauma center, between January 1, 2010, to December 31, 2021. Patients with admission weights falling above the 90th percentile of the Centers for Disease Control and Prevention's sex-specific growth charts were identified as overweight/obese, those below the cutoff were categorized as nonobese. Groups were compared regarding demographics, mechanism of injury, Injury Severity Score, and Abbreviated Injury Scale by body region of injury. Outcome measures included hospital admission, length of hospital stay, intensive care unit (ICU) admission, ICU length of stay, and mortality. Of the 306 patients included, 72 (23.5%) were overweight/obese and 234 (76.5%) were nonobese. The mean Injury Severity Score scores were higher among overweight/obese patients (5.37 vs 8.74, P = 0.008). Overweight/obese children were more likely to sustain severe abdominal injuries (Abbreviated Injury Scale ≥ 3) (12.2% vs 5.1%; odds ratio [OR], 2.64; 95% CI, 1.07-6.56; P = 0.030), be admitted to the hospital (94.5% vs 74.3%; OR, 12.07; 95% CI, 2.87-50.72; P < 0.001), require ICU admission (31.0% vs 20.0%, OR, 1.87; 95% CI, 1.03-3.36; P = 0.036), and require a longer ICU stay (0.9 vs 0.4 days, P = 0.014) compared with nonobese patients. Obese and overweight children are at increased risk for higher injury severity scores, severe abdominal injuries, and ICU admission after pedestrian motor vehicle accidents.

Systematic review protocol of aetiology of mechanical bowel obstruction in low-and-middle income countries: Has anything changed in the last two decades?

The aetiology of mechanical bowel obstruction exhibits significant variability based on geographical location and age. In high-income countries, postoperative adhesions and hernias are frequently cited as the primary causes, whereas in low- and middle-income countries (LMCIs), hernias take precedence. Speculation exists within the surgical community regarding whether this trend has evolved in LMCIs. To address this knowledge gap, our study aims to conduct a systematic review of existing literature, focusing on understanding the most prevalent causes of mechanical bowel obstruction in both pediatric and adult populations within LMCIs, providing valuable insights for surgical practice. This protocol was designed and written according to the guidelines of the Preferred Reporting Items for Systematic Review and Meta-analysis Protocol 2015 (PRISMA-P 2015) statement. However, the results of the systematic review will be reported following the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. We will consider studies published in English and French between 2002 and 2022 that reported on the aetiology of mechanical bowel obstruction in any age group in low- and middle-income countries. We will conduct a literature search using Ovid MEDLINE, Ovid Embase, CINAHL on EBSCO and Web of Science databases employing relevant subject headings, keywords and synonyms, which will be combined using Boolean operators to refine the search results. A hand search of references of retrieved literature will be conducted. The retrieved articles will be imported into Zotero for de-duplication. The resulting set of titles and abstracts will be uploaded to Rayyan (an AI-assisted online systematic review tool), where they will be double-checked to identify articles eligible for inclusion. Two independent reviewers will screen articles to be included and disagreement will be resolved by discussion or by a third reviewer as a tie-breaker. Also, data extraction will be done by one reviewer and confirmed by another. Critical appraisal to assess the quality of the included studies will be carried out by two independent reviewers using the Joanna Briggs Institute (JBI) tools. We anticipate that the eligible studies will be quite heterogeneous in terms of their design, outcomes of interest, populations and comorbidities. Therefore, resmay be synthesised descriptively without meta-analysis using charts, graphs and tables. Where possible, we will conduct a sub-analysis using conceptual frameworks based on age, WHO regions and continents.

Proteomic change in the upper lobe of the left lung of Beagle dogs at the lung migration stage of Toxocara canis infection

BackgroundToxocara canis is considered one of the most neglected parasitic zoonoses and threatens the health of millions of people worldwide with a predilection for pediatric and adolescent populations in impoverished communities. Exploring the invasion and developmental mechanisms associated with T. canis infection in its definitive canine hosts will help to better control zoonotic toxocariasis.MethodsProteomic changes in samples from the upper lobe of the left lung of Beagle puppies were systematically analyzed by quantitative proteomic technology of data-independent acquisition (DIA) at 96 h post-infection (hpi) with T. canis. Proteins with P-values < 0.05 and fold change > 1.5 or < 0.67 were considered proteins with differential abundance (PDAs).ResultsA total of 28 downregulated PDAs and 407 upregulated PDAs were identified at 96 hpi, including RhoC, TM4SFs and LPCAT1, which could be associated with the maintenance and repair of lung homeostasis. GO annotation and KEGG pathway enrichment analyses of all identified proteins and PDAs revealed that many lung proteins have correlation to signal transduction, lipid metabolism and immune system.ConclusionsThe present study revealed lung proteomic alterations in Beagle dogs at the lung migration stage of T. canis infection and identified many PDAs of Beagle dog lung, which may play important roles in the pathogenesis of toxocariasis, warranting further experimental validation.Graphical

Caregivers with limited English proficiency: Satisfaction with primary pediatric healthcare.

With a growing 25.5 million people in the United States experiencing limited-English proficiency (LEP), there is a concern over these individuals' experiences in healthcare. Health outcomes of LEP status are well-documented for adults in hospitals; however, less is known about patient experience, pediatric populations, and primary care settings. This study investigated differences in caregiver satisfaction between families with and without LEP receiving healthcare for their child. A sample of 25,118 caregivers whose children from birth to 17years had met with any healthcare providers in the past year was used. Analyses consisted of unpaired t-tests comparing mean satisfaction of LEP and English-proficient (EP) caregivers in the domains of how often primary healthcare providers spent enough time with the child, listened, provided specific information, demonstrated sensitivity to the family's values, and made the respondent feel like a partner.
