and Its Treatment Impact on Immune-Mediated Ocular Diseases.

Purpose: (HP), which colonizes exclusively in the gastrointestinal tract, has been reported to dysregulate the immune response and gives rise to several extra-gastrointestinal autoimmune disorders. However, the relationship between HP and immune-mediated ocular diseases remains ambiguous. This study aims to clarify the association between immune-mediated ocular diseases and HP infection, as well as the impact of HP treatment on the incidence of immune-mediated ocular diseases.

Lipopolysaccharide-Induced Lysosomal Cell Death Through Reactive Oxygen Species in Rat Liver Cell Clone 9.

In sepsis, bacterial components, particularly lipopolysaccharide (LPS), trigger organ injuries such as liver dysfunction. Although sepsis induces hepatocyte damage, the mechanisms underlying sepsis-related hepatic failure remain unclear. In this study, we demonstrated that the LPS-treated rat hepatocyte cell line Clone 9 not only induced reactive oxygen species (ROS) generation and apoptosis but also increased the expression of the autophagy marker proteins LC3-II and p62, and decreased the expression of intact Lamp2A, a lysosomal membrane protein.

Heat shock protein 70 protects the lungs from hyperoxic injury in a neonatal rat model of bronchopulmonary dysplasia.

Hyperoxia plays a significant role in the pathogenesis of lung injury, such as bronchopulmonary dysplasia (BPD), in premature infants or newborns. BPD management aims to minimize further injury, provide an optimal environment to support growth and recovery. In clinic neonatal care, we need a new therapy for BPD.

Small Airway Dysfunction Measured by Impulse Oscillometry and Fractional Exhaled Nitric Oxide Is Associated With Asthma Control in Children.

Background: Impulse oscillometry (IOS) and fractional exhaled nitric oxide (FeNO) are sensitive and non-invasive methods to measure airway resistance and inflammation, although there are limited population-based studies using IOS and FeNO to predict asthma control.

Objective: This study aimed to investigate the utility of IOS and FeNO for assessing childhood asthma control in terms of small airway dysfunction and airway inflammation.

Methods: This prospective observational cohort study enrolled 5,018 school children (aged 6-12 years), including 560 asthmatic children and 140 normal participants.

Using a neonatal rat model to explore the therapeutic potential of coenzyme Q10 in prematurity under hyperoxia.

Hyperoxia, is often used in preterm supportive care, leading to high oxygen exposure in neonates. Coenzyme Q10 (CoQ10) is a free radical scavenger that has been studied in older children but never be investigated for its role in preterm care. We hypothesize that the administration of exogenous CoQ10 would raise serum concentrations of CoQ10 and mitigate the adverse effects of hyperoxia on the organs by reducing oxygen-free radicals and inflammation.

Altered Pattern of Macrophage Polarization as a Biomarker for Severity of Childhood Asthma.

Purpose: Asthma causes a substantial morbidity and mortality burden in children and the pathogenesis of childhood asthma is not completely understood. Macrophages are heterogeneous with divergent M1/M2 polarization phenotypes in response to various stimulations during the inflammatory process. We aimed to investigate the pattern of macrophage polarization and its association with severity and exacerbation in asthmatic children.

Implementation of nutrition practice improves growth velocity and weight gain in premature infants ≤ 1250 grams.

Background: The concept of parental nutritional care for premature infants has been applied and advanced over the past decade. This study compared the clinical outcomes before and after nutrition practice (NP) implementation and evaluated the effects of implementation on growth velocity and weight gain in premature infants.

Methods: Descriptive data of premature infants (gestational age < 30 weeks; body weight ≤ 1250 g) born 4 years before and after NP implementation were retrospectively reviewed in a neonatal intensive care unit at a hospital in Taiwan.

M2-like polarization of THP-1 monocyte-derived macrophages under chronic iron overload.

Macrophages are characterized by phenotypical and functional heterogeneity. In different microenvironments, macrophages can polarize into two types: classically activated macrophages (M1) or alternatively activated macrophages (M2). M1 macrophages are a well-known bacteriostatic macrophage, and conversely, M2 macrophages may play an important role in tumor growth and tissue remodeling.

Subcutaneous injection of recombinant heat shock protein 70 ameliorates atopic dermatitis skin lesions in a mouse model.

Atopic dermatitis (AD) is a chronic inflammatory skin disease and sometimes is a tough challenge for physicians. We previously reported that in Th2 environment, the production and secretion of thymic stromal lymphopoietin (TSLP) from human keratinocytes was inhibited by recombinant heat shock protein 70 (rHSP70). The present study assessed the therapeutic effectiveness of rHSP70 in a mouse model of AD.

Effects of vitamin B-6 supplementation on oxidative stress and inflammatory response in neonatal rats receiving hyperoxia therapy.

Hyperoxia is often used in the treatment of neonates. However, protracted use of hyperoxia leads to significant morbidity. The purpose of this study was to evaluate the effects of vitamin B-6 supplementation on oxidative stress and inflammatory responses in neonatal rats undergoing hyperoxia therapy.

Personal History and Physical Examination in Judgment of Urinary Tract Infection in Children Aged 3 Months to 2 Years.

Background: Pediatricians ubiquitously rely on urine analysis for diagnosing urinary tract infection (UTI) in young febrile children due to discrepancies in symptom presentation. This study aimed to identify the determinants of physical examination and personal history for diagnosing UTI.

Methods: Four hundred and ten patients aged between 3 months and 2 years presenting with a tympanic temperature of >38°C for >24 hours were requested to undergo urinary tests.

Heat-shock pretreatment reduces expression and release of TSLP from keratinocytes under Th2 environment.

Background: Atopic dermatitis is a chronic, relapsing inflammatory disease of the skin. Current therapy is not curative, and recalcitrant disease is a big stress and challenge for parents and physicians. This study explored the potential role of heat-shock protein 70 (HSP-70) and its anti-inflammatory effects on keratinocyte under TH2 environment.

Wheezing as a sign of cor triatriatum sinister culminating in multiple organ failure.

Cardiac asthma or cardiac wheezing (CW) refers to a syndrome of dyspnea and wheezing that mimicks asthma clinically. Reported herein is the case of a 2-month-old boy who presented with refractory wheezing as a sign of cor triatriatum sinister (CTS) that culminated in overwhelming multiple organ failure in a short time. On the day of admission, oxygen saturation (SpO2 ) was <80%.

Correlations between pulmonary function and childhood asthma control test results in 5-11-year-old children with asthma.

Objectives: We examined correlations between the two asthma assessment tools, pulmonary function tests, and Childhood Asthma Control Test (C-ACT) scores, in 5-11-year-old children with asthma to determine if the C-ACT scores could predict pulmonary function test results.

Materials And Methods: A total of 172 children with asthma aged 5-11 years completed C-ACT questionnaires and underwent pulmonary function testing. Correlations between these test results were examined.

New plasma separation glucose oxidase-based glucometer in monitoring of blood with different PO2 levels.

Background: The PalmLab glucometer is a newly designed plasma separation glucose oxidase (GO)-based glucometer. Past studies have shown that the accuracy of GO-based glucometers is compromised when measurements are taken in patients with high PO(2) levels. We performed a two-arm study comparing the fitness of the PalmLab blood glucometer with that of a standard glucose analyzer in monitoring blood glucose levels in pediatric patients, especially when arterial partial pressure of oxygen (PO(2)) was high.

Quantitative assessment of disease involvement by follicular lymphoma using real-time polymerase chain reaction measurement of t(14;18)-carrying cells.

Chromosomal translocation t(14:18)(q32;q21) is one of the most common karyotypic abnormalities in non-Hodgkin's lymphomas. It occurs in more than 85% of follicular lymphoma (FL) cases. Real-time polymerase chain reaction (Q-Rt-PCR) analysis using double-labeled fluorogenic probes is a new tool in the detection and quantification of t(14;18)-carrying cells.

Molecular response of follicular lymphoma to cyclophosphamide, doxorubicin, vincristine, prednisone C(H)OP or COP-based therapy as measured by polymerase chain reaction evidence of translocation (14;18)(q32;q21).

Purpose: Existing data suggest that conventional C(H)OP (cyclophosphamide, doxorubicin, vincristine, prednisone) regimen may not be intensive enough to achieve molecular response, as measured by polymerase chain reaction (PCR) evidence of translocation (14;18)(q32:q21) for follicular lymphoma. This study was undertaken to study the molecular response rate of follicular lymphoma to C(H)OP-based therapy and to analyze prognostic factors for molecular response.

Patients And Methods: Twenty patients with pretreatment PCR evidence of t(14;18)(q32; q21) and at least one posttreatment PCR analysis after the initiation of the treatment with C(H)OP with or without radiation therapy constituted the basis for this analysis.
