Innovative air mattress for the prevention of pressure ulcers in neonates.

OBJECTIVE: Pressure ulcers (PUs) severely impact health outcomes in neonatal intensive care, with up to 28% prevalence and doubled mortality rates. Due to their only partially developed stratum corneum, neonates are highly susceptible to PUs because of a lack of adequate support surfaces. The occipital region of the head and hip are the main risk areas due to immobility and newborn body proportions. The main goal of the study was to investigate the impact of reduction in local pressure in these body areas by two air mattress designs and different filling states. METHOD: Two innovative air-filled mattress prototypes (prototype 1 and prototype 2), consisting of three different segments (head, trunk and feet regions), were developed to reduce local interface pressures by optimising pressure distribution, and were assessed with three air pressure filling states (0.2kPa, 0.4kPa and 0.6kPa). A baby doll was used to investigate pressure distribution and local pressure impact. It measured 51cm and the weight was modified to be 1.3kg, 2.3kg and 3.3kg, representing premature to term newborn weights, respectively. A specialised foam mattress and an unsupported surface were considered as controls. RESULTS: The interface pressures at the hip region for newborn models could be reduced by up to 41% with mattress prototype 1 and 49% with prototype 2 when filled with 0.2kPa air pressure. It was found that the size and the pressure inside air segments was crucial for interface pressure. CONCLUSION: Our results demonstrated that air mattresses achieved lower interface pressures compared to conventional support surfaces, and that the benefit of the air mattresses depended on their filling status. The importance of using innovative, segmented designs that were tailored to meet the specific needs of highly vulnerable paediatric patients was demonstrated.

Role, education, policies and competencies for advanced practice in paediatric haematology-oncology nursing in Europe: A scoping review.

The aim of this scoping review is to describe the role, education, policies/regulation, skills and competencies required for advanced practice in paediatric haematology-oncology nursing in Europe, highlighting the differences in development between the different European countries. A scoping review was conducted following the methodological framework of guidelines by Arksey and O'Malley and the recommendations for advancing the methodology by Levac et al. We searched MEDLINE/PubMed, EMBASE, CINAHL, Cochrane Library, Scopus, grey literature, webpages, reference lists and performed a manual search, without any restrictions on language or time. The intersection between databases, grey literature and evidence documents traced from the sites of the most authoritative European organisations in the field made it possible to identify the regulatory and training differences between the various countries that were examined. This scoping review highlights how advanced knowledge and competences are used in the care of paediatric haematology-oncology patients, which are strictly necessary for implementing quality care. At present these competences are not recognised in policies and regulation in most of the countries that were examined. It is desirable that all EU member states work to implement a radical change and allow these more competent figures to assist patients in the best possible way.

Paediatrics and discomfort with death and dying.

Death and dying, while uncommon in day-to-day paediatrics practice, are becoming increasingly common occurrences as children with life-limiting illnesses are living longer. We reflect on our experiences with death and dying in our residency training and whether paediatrics, as a specialty, is uncomfortable with death. Paediatric trainees should be included in honest discussions about disease trajectories and participate in providing end-of-life care. Anticipatory guidance helps personalize care and can prevent unnecessary procedures or suffering that patients may experience. While trainees may not be present at the end-of-life for many patients, managing death and dying are important competencies for future paediatricians. Current paediatricians should reflect on their comfort with death and how this may impact their patient care.

Antimicrobial susceptibility profiles of invasive bacterial infections among children from low- and middle-income countries in the Western Pacific Region (WPRO) - a systematic review and meta-analysis.

Background: Antimicrobial resistance increasingly impacts paediatric mortality, particularly in resource-constrained settings. We aimed to evaluate the susceptibility profiles of bacteria causing infections in children from the Western Pacific region. Methods: We conducted a systematic review and meta-analysis of bacteria responsible for common infections in children. We included studies published from January 2011 to December 2023 (PROSPERO CRD42021248722). Pooled susceptibilities were evaluated against empiric antibiotics recommended to treat common clinical syndromes. Findings: Fifty-one papers met inclusion criteria, incorporating 18,330 bacterial isolates. Of available published data, only six countries from the region were represented. Escherichia coli revealed a pooled susceptibility to ampicillin of 17% (95% CI 12-23%, n = 3292), gentamicin 63% (95% CI 59-67%, n = 3956), and third-generation cephalosporins 59% (95% CI 49-69%, n = 3585). Susceptibility of Klebsiella spp. to gentamicin was 71% (95% CI 61-80%, n = 2323), third-generation cephalosporins 35% (95% CI 22-49%, n = 2076), and carbapenems 89% (95% CI 78-97%, n = 2080). Pooled susceptibility of Staphylococcus aureus to flucloxacillin was 72% (95% CI 58-83%, n = 1666), and susceptibility of Streptococcus pneumoniae meningitis isolates to ampicillin was 26% (95% CI 11-44%, n = 375), and 63% (95% CI 40-84%, n = 246) to third-generation cephalosporins. Interpretation: The burden of antimicrobial resistance among bacteria responsible for common infections in children across the Western Pacific region is significant, and the currently recommended World Health Organization antibiotics to treat these infections may be inefficacious. Strategies to improve the availability of high-quality data to understand the burden of antimicrobial resistance in the region are necessary. Funding: The study was supported by an Australian GovernmentNational Health and Medical Research Council Investigator Grant. This research was funded in part by the Wellcome Trust [220211/Z/20/Z].

Biomarkers to predict and diagnose pulmonary complications in children post haematopoietic stem cell transplant.

OBJECTIVES: Haematopoietic cell transplant (HCT) is a cellular therapy for a group of high-risk children with cancer, immunodeficiency and metabolic disorders. Whilst curative for a child's underlying condition, HCT has significant risks associated, including lung injury. These complications are associated with increased post HCT mortality and require improved methods of risk stratification, diagnosis and treatment. METHODS: Biomarkers measured in bronchoalveolar fluid and peripheral blood have been identified for both acute and chronic lung injury post HCT.This review evaluates the current research available investigating the use of these biomarkers to improve clinical care, with a focus on the paediatric cohort. RESULTS: Elevated levels of cytokines such as IL-6, IL-8, G-CSF and TNF were identified as potential predictive biomarkers for the development of post HCT lung disease. The pulmonary microbiome was found to have strong potential as a biomarker pre and post HCT for the development of pulmonary complications. General limitations of the studies identified were study design, retrospective or single centre and not exclusively performed in the paediatric population. CONCLUSION: To translate biomarker discovery into clinical implementation further research is required, utilising larger cohorts of children in prospective trials to validate these biomarkers and determine how they can be translated into better outcomes for children post HCT.

Pulmonary complications post allogeneic haematopoietic stem cell transplant in children.

Objectives: Haematopoietic stem cell transplant (HCT) is a cellular therapy that, whilst curative for a child's underlying disease, carries significant risk of mortality, including because of pulmonary complications. The aims of this study were to describe the burden of pulmonary complications post-HCT in a cohort of Australian children and identify risk factors for the development of these complications. Methods: Patients were identified from the HCT databases at two paediatric transplant centres in Australia. Medical records were reviewed, and demographics, HCT characteristics and pulmonary complications documented. Relative risk ratio was used to identify risk factors for developing pulmonary complications prior to first transplant episode, and survival analysis performed to determine hazard ratio. Results: In total, 243 children underwent transplant during the study period, and pulmonary complications occurred in 48% (117/243) of children. Infectious complications were more common (55%) than non-infective complications (18%) and 26% of patients developed both. Risk factors for the development of pulmonary complications included the following: diagnoses of MPAL (RR 2.16, P = 0.02), matched unrelated donor (RR1.34, P = 0.03), peripheral blood (RR 1.36, P = 0.028) or cord blood (RR 1.73, P = 0.012) as the stem cell source and pre-existing lung disease (RR1.72, P < 0.0001). Children with a post-HCT lung complication had a significantly increased risk of mortality compared with those who did not (HR 3.9, P < 0.0001). Conclusion: This study demonstrates pulmonary complications continue to occur frequently in children post-HCT and contribute significantly to mortality. Highlighting the need for improved strategies to identify patients at risk pre-transplant and enhanced treatments for those who develop lung disease.

Clinical and diagnostic features of central nervous system tuberculosis in Indian children - a descriptive study.

Background: Children with tuberculous meningitis (TBM) present with diagnostic challenges as they often have atypical clinical features. Objective: To describe the baseline characteristic features of children diagnosed with central nervous system (CNS) TB (TBM and tuberculoma). Design: Retrospective descriptive study. Methods: Children less than 12 years presenting with neurological signs and symptoms were assessed for a therapeutic TBM trial eligibility. The results of their clinical, laboratory, neuroimaging, cerebrospinal fluid evaluations were analysed for TBM diagnosis. Results: Of 600 children evaluated, 61(10%) had CNS tuberculosis; TBM 47, tuberculoma 14. 20(33%) had definite TBM. Mean age of children with TBM was 5 ± 3.4 years. Of 47, 13(28%), 21(45%) and 13(28%) had grade I, II, and III disease respectively. Abnormalities suggestive of TBM in MRI and computed tomography brain were observed in 76% (26/34) and 77% (24/31) respectively. Abnormal cerebrospinal fluid white blood cell count, protein and glucose were observed in 56% (24/43), 49% (22/45), 47% (21/45) respectively. Among 41 patients with TBM followed up until discharge, five died. Conclusion: Younger children with TBM have severe forms. Confirmatory results may not be available in all. A holistic approach to care including addressing complications of hydrocephalus and strokes is needed.

Clinical features, results of brain imaging and other tests in the cerebrospinal fluid among children diagnosed with tuberculous meningitis ­ descriptive study Why was the study done? What did the researchers do? Records of children aged between 6 months and 12 years who presented to the health care centre with signs and symptoms of central nervous system (CNS) disease and assessed for tuberculous meningitis (TBM) clinical trial eligibility were reviewed. The research team studied the signs and symptoms of the TBM, results of the CT/MRI brain scan and tests which were done in the cerebrospinal fluid (CSF) during hospitalization. What did the researchers find? Total number of children who presented to the health centre during the study period with CNS complaints and underwent lumbar puncture were 600. Among them 61 were diagnosed with CNS TB (47 had TBM and 14 had tuberculoma). Half of them were less than five years of age. Ten had neurological dysfunction. Fever, vomiting were the common complaints. Almost half of the children had vomiting, altered level of consciousness and seizures. Tests done in the CSF detected the bacteria causing TBM in half of the children. Abnormal cell counts or biochemical changes in the CSF specific to TBM were observed in half of the children. Abnormalities in CT/MRI imaging with features specific to the disease were observed in closer to three fourth of the children. What do the findings mean? Children with TBM often present late for care with severe forms and its complications. There would be diagnostic challenges as the symptoms were vague and might not present in a specific manner, specific tests in the CSF could be negative and if undiagnosed could lead to severe morbidity impacting the quality of life or death. Taking the overall picture of presenting complaints, results of CSF test and brain scan and with high degree of suspicion, TBM should be diagnosed early and managed appropriately.

Low-Level BCR::ABL1 Transcript at Diagnosis in Childhood Leukemia: A 10-Year Single Institution Study.

INTRODUCTION: Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) is a high risk form of ALL associated with dismal outcomes in the pre-tyrosine kinase inhibitor (TKI) era. Addition of a TKI to chemotherapy improves outcomes. Therefore, testing for the presence of the Philadelphia chromosome by at least two methods at the time of diagnosis is critical. Diagnostic testing may include karyotype, fluorescent in situ hybridisation (FISH), and RT-PCR for the BCR::ABL1 transcript. The significance of low-level BCR::ABL1 transcript by RT-PCR in the absence of the Philadelphia chromosome on karyotype or by FISH is unknown. METHODS: This is a retrospective review of children diagnosed with acute leukemia at our institution from 2010 to 2020. Those positive for the BCR::ABL1 transcript by qualitative RT-PCR, and negative for t(9;22) by karyotype or FISH were analyzed for demographics, cytogenetic and molecular features at diagnosis and relapse, treatment and outcomes. The Kaplan-Meier method was used to estimate event-free and overall survival. RESULTS: Forty-seven of 306 (15%) patients with Ph- ALL had low-level BCR::ABL1 detected by RT-PCR. Most (77%) had B-cell ALL. The e1a2 transcript was detected most frequently, in 43 (91%) patients. BCR::ABL1 was quantifiable in 12/43 (28%) patients, with a median of 0.0008% (range 0.0003-0.095%). Seven patients (15%) relapsed. No patient with low-level BCR::ABL1 at diagnosis developed Ph + ALL at relapse. There was no difference in 5-year event-free (77% versus 81%, p = 0.407) or overall survival (86% versus 91%, p = 0.3) between children with low-level BCR::ABL1 (n = 47) and those without (n = 259). CONCLUSION: BCR::ABL1 low-level positivity in children with newly diagnosed Ph- ALL is a relatively common finding and did not adversely affect outcome for patients treated using a contemporary risk-adapted approach.

Synchronous intracranial arteriovenous malformation and papillary glioneuronal tumour: hypothesis or reality?

Brain arteriovenous malformations (AVM) rarely occur with spatial and/or temporal co-localisation to intracranial neoplasms. Most prior reports describe this association with high-grade gliomas; however, reports of a co-occurrence with low grade gliomas are very rare. It is unclear whether such cases represent a true co-occurrence of separate pathologies or simply an unusually vascular phenotype of the neoplasm. Most such reports pre-date the era of molecularly defined gliomas. We present the first report of the spatial and temporal co-occurrence of an intracranial arteriovenous malformation traversing and within a papillary glioneuronal tumour, molecularly defined by the presence of SLC44A1::PRKCA fusion. This case was successfully managed by resection of both lesions adhering to the principles of AVM surgery. It is possible these exceptionally rare co-occurrences may have common underlying molecular drivers relating to the mitogen activated protein kinase (MAPK) pathway.

Patient safety incidents in paediatric radiology: how to care for the professional?

Patient safety incidents in paediatric radiology have profound impacts not only on the patient and their family, but also on the well-being and professional practice of healthcare professionals. These incidents, which range from procedural and diagnostic incidents to serious adverse events leading to harm or even death of the patient, may evoke feelings of distress, guilt, and anxiety among paediatric radiologists (in-training), ultimately affecting their confidence and ability to deliver high-quality care. Recognizing the importance of addressing these challenges, healthcare organizations should implement strategies to support professionals in coping with and learning from these incidents. By fostering a culture of open communication, providing access to peer support, and offering structured debriefing and educational opportunities, healthcare institutions can help mitigate the psychological toll of patient safety incidents and promote resilience among their staff. This article examines the multifaceted impacts of patient safety incidents on paediatric radiologists (in-training) and their staff and outlines effective approaches for handling these incidents to support professional well-being and enhance patient safety.

Assessing the Evidence for Nonobstetric Risk Factors for Deformational Plagiocephaly: Systematic Review and Meta-Analysis.

BACKGROUND: Plagiocephaly is defined as an asymmetrical distortion of the skull, resulting in an oblique trapezoid or parallelogram head shape. Deformational plagiocephaly (DP) is caused by forces acting on one side of the back of the head, distorting normal skull symmetry. OBJECTIVE: The aims of this systematic review and meta-analysis were to critically assess the evidence for nonobstetric risk factors for DP and to make evidence-based recommendations for reducing the prevalence of DP. METHODS: The selection criterion was studies reporting risk factors for DP. Case reviews, case series, expert opinions, and systematic reviews were excluded. PubMed and Web of Science were searched from August 21, 2010, to August 21, 2022. Publication bias was assessed using funnel plots. Meta-analyses were presented using forest plots. RESULTS: A total of 19 studies (cohort studies: n=13, 68%; case-control studies: n=5, 26%; and cross-sectional studies: n=1, 5%) with a total of 14,808 participants were included. Of the 43 investigated potential nonobstetric factors, 16 (37%) were associated with DP. Of these 16 factors, 12 (75%) had odds ratios (ORs) with 95% CIs not crossing 1: insufficient vitamin D intake (OR 7.15, 95% CI 3.77-13.54), head position preference (OR 4.75, 95% CI 3.36-6.73), bottle-only feeding (OR 4.65, 95% CI 2.70-8.00), reduced tummy time (OR 3.51, 95% CI 1.71-7.21), sleeping position (OR 3.12, 95% CI 2.21-4.39), fewer motor milestones reached by the age of 6 months (OR 2.56, 95% CI 1.66-3.96), obesity (OR 2.45, 95% CI 1.02-5.90), maternal education level (OR 1.66, 95% CI 1.17-2.37), male sex (OR 1.51, 95% CI 1.07-2.12), formula feeding (OR 1.51, 95% CI 1.00-2.27), head circumference (OR 1.22, 95% CI 1.06-1.40), and mechanical ventilation (OR 1.10, 95% CI 1.00-1.14). No evidence of publication bias was detected. CONCLUSIONS: This study provides a comprehensive assessment of the nonobstetric factors associated with DP and presents 11 evidence-based recommendations for reducing its prevalence. The primary limitation is that only publication bias was assessed. TRIAL REGISTRATION: PROSPERO CRD42020204979; https://www.crd.york.ac.uk/prospero/display_record.php? ID=CRD42020204979.

A Behavior-Based Model to Validate Electronic Systems Designed to Collect Patient-Reported Outcomes: Model Development and Application.

BACKGROUND: The merits of technology have been adopted in capturing patient-reported outcomes (PROs) by incorporating PROs into electronic systems. Following the development of an electronic system, evaluation of system performance is crucial to ensuring the collection of meaningful data. In contemporary PRO literature, electronic system validation is overlooked, and evidence on validation methods is lacking. OBJECTIVE: This study aims to introduce a generalized concept to guide electronic patient-reported outcome (ePRO) providers in planning for system-specific validation methods. METHODS: Since electronic systems are essentially products of software engineering endeavors, electronic systems used to collect PRO should be viewed from a computer science perspective with consideration to the health care environment. On this basis, a testing model was blueprinted and applied to a newly developed ePRO system designed for clinical use in pediatric dentistry (electronic Personal Assessment Questionnaire-Paediatric Dentistry) to investigate its thoroughness. RESULTS: A behavior-based model of ePRO system validation was developed based on the principles of user acceptance testing and patient-centered care. The model allows systematic inspection of system specifications and identification of technical errors through simulated positive and negative usage pathways in open and closed environments. The model was able to detect 15 positive errors with 1 unfavorable response when applied to electronic Personal Assessment Questionnaire-Paediatric Dentistry system testing. CONCLUSIONS: The application of the behavior-based model to a newly developed ePRO system showed a high ability for technical error detection in a systematic fashion. The proposed model will increase confidence in the validity of ePRO systems as data collection tools in future research and clinical practice.

Salbutamol safety in children under 2 years of age with acute wheezing: a meta-analysis of randomised controlled trials.

OBJECTIVE: To evaluate the safety of short-term use of inhaled salbutamol in children under 2 years of age with acute wheezing. DATA SOURCES: Electronic databases (PubMed, Trip, MEDLINE) and the Cochrane Library were searched for studies published up to October 2022. STUDY SELECTION: The search was restricted to randomised controlled trials published in English regarding the safety of inhaled salbutamol in wheezing children under the age of 2. DATA EXTRACTION AND SYNTHESIS: The literature search strategy yielded 3532 references. The meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. MAIN OUTCOMES AND MEASURES: The incidence of adverse reactions associated with inhaled salbutamol administration compared with placebo. RESULTS: A total of 24 records were included. In 7 studies involving 597 patients, inhaled salbutamol was compared with controls and no statistically significant difference in the incidence of adverse drug reactions was found between the two groups (OR 2.12, 95% CI 0.69 to 6.51; p=0.19). Salbutamol administration via nebulisation was associated with an increased incidence of adverse reactions (OR 6.76, 95% CI 2.01 to 22.71; p=0.002). None of the studies reported severe cardiac side effects that necessitated withdrawal from the study following salbutamol administration. Only one study reported a significant non-cardiac side effect (severe tremulousness) that necessitated withdrawal from therapy. CONCLUSIONS: Inhaled salbutamol can be safely used in children under 2 years of age with acute wheeze with the administration via a metered-dose inhaler being potentially safer than a nebulised formulation. Neither of the formulations was associated with severe adverse effects.

Postural Stability in Children with Cerebral Palsy.

Background: A lack of postural control is one of the key problems in children with cerebral palsy (CP). The goals of the present study were to assess static postural stability in children with mild CP using a force platform compared to that of typically developing peers and to identify differences in static stability between children with hemiplegic and diplegic CP. Methods: This study included 45 children with hemiplegic CP and 45 children with well-functioning diplegic CP (Gross Motor Function Classification System; GMFCS scores between I and II) who were patients of local paediatric rehabilitation centres. The testing procedure included two interrelated parts: (1) the analysis of the body weight distribution and (2) the posturometric test (the centre of pressure; CoP measurements) using the force platform. Results: The results of the present study show that children with CP, compared to their TD peers, demonstrated significantly higher values for all of the analysed indexes of postural stability. The obtained results indicate differences in disorders of static postural stability between children with hemiplegic and diplegic CP. Compared to their TD peers, children with hemiplegic CP showed greater body weight asymmetry between the affected and unaffected sides of the body and greater CoP sway in the medial-lateral direction. In contrast, children with diplegic CP exhibited greater CoP displacements in the anterior-posterior direction. Conclusions: The findings of the present study show that (1) children with CP have increased static postural instability compared to their TD peers and (2) children with diplegic CP exhibit weaker mediolateral stability in standing, whereas children with hemiplegic CP show reduced anterior-posterior stability.

Therapeutic Drug Monitoring of antibiotic and antifungical drugs in paediatric and newborn patients. Consensus Guidelines of the Spanish Society of Hospital Pharmacy (SEFH) and the Spanish Society of Paediatric Infectious Diseases (SEIP).

Therapeutic monitoring of antibiotics and antifungals based on pharmacokinetic and pharmacodynamic (PK/PD) parameters is a strategy increasingly used for the optimization of therapy to improve efficacy, reduce the occurrence of toxicities, and prevent the selection of antimicrobial resistance, particularly in vulnerable patients including neonates and the critical or immunocompromised paediatric host. In neonates and children, infections account for a high percentage of hospital admissions, and anti-infectives are the most used drugs. However, paediatric PK/PD studies and the evidence regarding the efficacy and safety of some newly marketed antibiotics and antifungals-usually used off-label in paediatrics-to determine the optimal drug dosage regimens are limited. It is widely known that this population presents important differences in the PK parameters (especially in drug clearance and volume of distribution) in comparison with adults that may alter antimicrobial exposure and, therefore, compromise treatment success. In addition, paediatric patients are more susceptible to potential adverse drug effects and they need closer monitoring. The aim of this document, developed jointly by the Spanish Society of Hospital Pharmacy and the Spanish Society of Paediatric Infectious Diseases, is to describe the available evidence on the indications for therapeutic drug monitoring (TDM) of antibiotics and antifungals in newborn and paediatric patients, and to provide practical recommendations for TDM in routine clinical practice to optimise their dosing, efficacy and safety. Of antibiotics and antifungals in the paediatric population.

Effectiveness of text message reminders on paediatric appointment adherence: a systematic review and meta-analysis.

Attending health appointments is important for the paediatric population, as it allows for earlier detection of health issues and subsequent necessary treatments. It also ensures timely immunisations while also allowing patients or their parents to raise health concerns. Hence, it is crucial to take steps to ensure that such medical appointments are attended. To evaluate the effectiveness of text message reminders (TMRs) in improving paediatric patients' adherence to their appointments. A systematic review and meta-analysis were conducted. The search spanned across eight online databases from their inception dates to January 2024. The random-effects model was utilised to conduct the meta-analysis, where risk ratio was used as the effect measure. Subgroup analyses were conducted for age, number of TMRs sent, and type of appointments attended. In total, 13 studies were included. Compared to standard care (involving non-text message reminders or no reminders), TMRs were significantly more effective in improving appointment attendance among the paediatric population. Significant subgroup differences were found in the type of appointments attended, where TMRs were more effective for medical appointments compared to vaccination appointments. No differences in adherence to appointments were found across age groups or the number of TMRs sent.   Conclusion: Sending TMRs can be a potentially cost-effective way to improve the attendance rate of paediatric medical appointments, given the ease of implementation and the extensive mobile phone usage globally. Future studies should compare TMRs to other modes of automated reminders such as telephone messages or emails, to identify the most optimal method of delivery.   Trial registration: PROSPERO (CRD42023464893).

Associations of serum 25-hydroxyvitamin D with hsCRP and other novel inflammatory biomarkers in children: a cross-sectional study.

OBJECTIVE: Previous studies have shown the anti-inflammatory effect of 25-hydroxyvitamin D (25(OH)D) and the crucial roles of high-sensitive C reactive protein (hsCRP) and novel inflammatory markers (red blood cell distribution width-platelet count ratio (RDWPCR), mean platelet volume-platelet count ratio (MPVPCR), neutrophil-lymphocyte ratio (NLR) and white blood cell-neutrophil ratios (WBCNR)) in several diseases, but scarce data explored the associations of 25(OH)D with hsCRP and novel inflammatory markers. This study aimed to investigate these associations in children. DESIGN: Cross-sectional study. SETTING: Children in China. PARTICIPANTS: 10141 children (mean age 14.6 months) were included. PRIMARY AND SECONDARY OUTCOME MEASURES: HsCRP, red blood cell distribution width, platelet count, mean platelet volume, neutrophil, lymphocyte and white blood cell were measured. RESULTS: Overall, serum 25(OH)D was inversely associated with hsCRP and novel inflammatory biomarkers. In multivariable analysis, serum 25(OH)D was inversely associated with hsCRP and novel inflammatory biomarkers (Q quartile (Q) 4 vs Q1: 1129.75 vs 2090.99 for hsCRP; 4246.94 vs 6829.89 for RDWPCR; 4863.57 vs 5545.66 for MPVPCR; 4345.76 vs 6507.46 for NLR; 2418.84 vs 2868.39 for WBCNR). Similar results also were observed in stratified analyses by sex (boys and girls). Moreover, serum 25(OH)D was inversely associated with elevated inflammation levels. After adjustment for other potential covariates, inverse associations between serum 25(OH)D and elevated inflammation levels were still observed. The corresponding ORs (95% CI) were 0.05 (0.04, 0.06) for hsCRP, 0.13 (0.11, 0.15) for RDWPCR, 0.74 (0.64, 0.85) for MPVPCR, 0.11 (0.09, 0.13) for NLR and 0.57 (0.49, 0.66) for WBCNR in the fourth quartile compared with the first quartile, respectively. CONCLUSIONS: Generally, the graded and inverse associations of serum 25(OH)D with hsCRP and four novel inflammatory markers (RDWPCR, MPVPCR, NLR and WBCNR) were observed. The present study provided further support for the anti-inflammatory effects of 25(OH)D.

Chemo mechanical caries removal CMCR: Efficacy of Carisolv gel in primary molar teeth.

Objectives: To evaluate the efficacy of CariSolv gel with respect to chemo-mechanical caries removal in primary molar teeth. METHODS: The cross-sectional study was conducted at the Department of Paediatric Dentistry, Bakhtawar Amin Dental College and Hospital, Multan, Pakistan, from July to December 2022, and comprised patients of either gender aged 6-12 years having vital, primary molar teeth with clinical and radiographic evidence of carious lesion. Freshly prepared CariSolv gel 0.2 ml to 1.0ml was applied to carious dentine for a minimum of 30 seconds, using chemo-mechanical caries removal hand instruments. The cavity preparation was rinsed and dried. Image caries detector dye was applied by micro brush for 10 seconds. After the cavity preparation was washed and dried, any red-stained dentine indicated residual infected dentine. A maximum of 3 chemo-mechanical caries removal cycles were allowed. Data was analysed using SPSS 26.0. RESULTS: Of the 134 patients, 74(55.2%) were boys and 60(44.8%) were girls. The overall mean age was 8.55±1.58 years. The procedure was successful in 115(85.8%) cases. Age and gender were not significantly associated with the outcome (p>0.05). CONCLUSIONS: Chemo-mechanical caries removal method using CariSolv gel was found to be a viable alternative to traditional drilling techniques for caries removal in primary molar teeth.

Paediatric computed tomography diagnostic reference levels in Africa: A systematic review.

INTRODUCTION: Improvements in computed tomography (CT) technology in terms of image quality and reduction in absorbed dose have increased its applications in medical imaging. Diagnostic reference levels (DRLs) help to identify high radiation doses that are unusually delivered to patients undergoing exposure to ionising radiation. The aim of this review was to provide an overview of published studies by African researchers towards establishing paediatric CT DRLs in Africa. METHODS: The search for articles was conducted using some relevant literature search engines including PubMed, Scopus, Science Direct, Google Scholar and Web of Science. Two reviewers were involved in the article selection process which involved a three-stage screening process of identifying; article titles, abstracts and full-test reading. RESULTS: One hundred and seventy-four articles were identified from the database, PubMed (30), Scopus (21), Google Scholar (53), Web of Science (25) and Science Direct (45). Fifty duplicated articles were excluded before screening. Twelve peer-reviewed articles were included in this study based on the inclusion criteria. DRL values in terms of computed tomography dose index volume of head for the age groupings 0-1, 1-5, 5-10 and 10-15 were 27, 36.6, 39.5 and 47.5 mGy while the dose length product values were 461.6, 664, 872 and 978 mGy.cm respectively. The DRLs were calculated as 75th percentile of the local DRLs reported by the 12 articles included in this review. CONCLUSION: This review has shown that only few of the African countries (19%) have published studies on paediatric CT DRLs. There were variations in the DRLs published by the various authors which indicate that harmonisation and standardisation of paediatric CT protocols is essential for the optimisation of paediatric doses.
