Antibody responses against influenza A decline with successive years of annual influenza vaccination.

Influenza vaccine effectiveness and immunogenicity can be compromised with repeated vaccination. We assessed immunological markers in a cohort of healthcare workers (HCW) from six public hospitals around Australia during 2020-2021. Sera were collected pre-vaccination and ~14 and ~180 days post-vaccination and assessed in haemagglutination inhibition assay against egg-grown vaccine and equivalent cell-grown viruses.

Nutrition literacy in Vietnamese pregnant women: a cross-sectional study.

Inadequate nutrition intake during pregnancy elevates the risk of adverse health outcomes during pregnancy, with potential long-term repercussions for both mother and child, extending to subsequent generations. Current initiatives to improve individual dietary habits emphasize promoting nutrition literacy (NL), which encompasses the ability to access, comprehend, and use basic nutrition information and services necessary for making appropriate nutrition decisions. However, there were limited data on the NL of pregnant women in Vietnam.

Updates on neonatal cell and novel therapeutics: Proceedings of the Second Neonatal Cell Therapies Symposium (2024).

Mesenchymal stromal cells, umbilical cord blood cells and neural stem cells translate from lab, to preclinical and into clinical trials, with contributions being made from all over the world. Effective and timely translation involves frequent reflection and consultation from research-adjacent fields (i.

Comparison of Random Forest and Stepwise Regression for Variable Selection Using Low Prevalence Predictors: A case Study in Paediatric Sepsis.

Introduction: Variable selection is a common technique to identify the most predictive variables from a pool of candidate predictors. Low prevalence predictors (LPPs) are frequently found in clinical data, yet few studies have explored their impact on model performance during variable selection. This study compared the Random Forest (RF) algorithm and stepwise regression (SWR) for variable selection using data from a paediatric sepsis screening tool, where 18 out of 32 predictors had a prevalence < 10%.

Biomarkers in Ataxia-Telangiectasia: a Systematic Review.

Ataxia-Telangiectasia (A-T) is a very rare multisystem disease of DNA repair, associated with progressive disabling neurological symptoms, respiratory failure, immunodeficiency and cancer predisposition, leading to premature death. There are no curative treatments available for A-T but clinical trials have begun. A major limiting factor in effectively evaluating therapies for A-T is the lack of suitable outcome measures and biomarkers.

Baseline Characteristics of Frailty and Disease Stage in Older People Living With CKD.

Introduction: The GOAL trial, a cluster randomized controlled trial, investigated the effect of comprehensive geriatric assessment (CGA) on frail older people with chronic kidney disease (CKD). This paper describes the following: (i) participant baseline characteristics, and (ii) their relationship with CKD stage and frailty severity.

Methods: Sixteen kidney outpatient clinics (clusters) were randomly allocated 1:1 to CGA or usual care.

Effect of Postoperative Neck-Shaft and Anteversion Angles on Biomechanical Outcomes in Proximal Femoral Osteotomy: An In Silico Study.

Effective surgical planning is crucial for maximizing patient outcomes following complex orthopedic procedures such as proximal femoral osteotomy. In silico simulations can be used to assess how surgical variations in proximal femur geometry, such as femur neck-shaft and anteversion angles, affect postoperative system mechanics. This study investigated the sensitivity of femur mechanics to postoperative neck-shaft angles, anteversion angles, and osteotomy contact areas using patient-specific finite element analysis informed by neuromusculoskeletal models.

Predictive equation derived from 6,497 doubly labelled water measurements enables the detection of erroneous self-reported energy intake.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

"That's not fair on my kid": Carers' perspectives on sport participation and experiences for children in out-of-home care.

Children in out-of-home care participate in less organised sport than children from other household structures, potentially reducing opportunities for improvements in social, developmental, and health outcomes. Despite this, little is known about barriers and facilitators of sport participation for children in care. We aimed to explore carers' perspectives on the influences on children in care's participation and experiences in organised sport.

Comparison of carbon dioxide control during pressure controlled versus pressure-regulated volume controlled ventilation in children (CoCO2): protocol for a pilot digital randomised controlled trial in a quaternary paediatric intensive care unit.

Introduction: Digital trials are a promising strategy to increase the evidence base for common interventions and may convey considerable efficiency benefits in trial conduct. Although paediatric intensive care units (PICUs) are rich in routine electronic data, highly pragmatic digital trials in this field remain scarce. There are unmet evidence needs for optimal mechanical ventilation modes in paediatric intensive care.

Young Adults with Type 1 Diabetes' Clinical Outcomes and Satisfaction Related to the Use of Videoconferencing for Type 1 Diabetes Healthcare: A Narrative Review.

Introduction: Young adulthood is well documented as being a particularly challenging area of type 1 diabetes (T1D) healthcare. Many young adults with T1D (YAT1D) are distracted from effective disease self-management; T1D healthcare service engagement can be problematic and inconsistent, and high rates of unplanned healthcare contacts prevail. Video conferencing use can facilitate services to be flexible and responsive.

Cemiplimab in recurrent cervical cancer: Final analysis of overall survival in the phase III EMPOWER-Cervical 1/GOG-3016/ENGOT-cx9 trial.

Aim: Cemiplimab has demonstrated significantly longer survival than physician's choice of chemotherapy in patients with recurrent cervical cancer after first-line platinum-containing chemotherapy. We report the final survival analysis from the phase III randomized study (EMPOWER-Cervical 1/GOG-3016/ENGOT-cx9).

Methods: Cemiplimab (n = 304) or chemotherapy (n = 304) were administered every 3 weeks.

Six months of hybrid closed-loop therapy improves diabetes-specific positive well-being, and reduces diabetes distress and fear of hypoglycemia: secondary analysis of a randomized controlled trial.

Introduction: This analysis aimed to investigate diabetes-specific psychological outcomes among adults with type 1 diabetes (T1D) using hybrid closed-loop (HCL) versus standard therapy.

Research Design And Methods: In this multicenter, open-label, randomized, controlled, parallel-group clinical trial, adults with T1D were allocated to 26 weeks of HCL (MiniMed™ 670G) or standard therapy (insulin pump or multiple daily injections without real-time continuous glucose monitoring). Psychological outcomes (awareness and fear of hypoglycemia; and diabetes-specific positive well-being, diabetes distress, diabetes treatment satisfaction, and diabetes-specific quality of life (QoL)) were measured at enrollment, mid-trial and end-trial.

Optimal timing for epinephrine administration in adult patients with out-of-hospital cardiac arrest: A retrospective observational study.

Background: This study aimed to clarify the appropriate timing for epinephrine administration in adults with out-of-hospital cardiac arrest (OHCA), particularly those cases with nonshockable rhythms, by addressing resuscitation time bias.

Methods: We performed a retrospective observational study utilizing a multicenter OHCA registry involving 95 hospitals in Japan between June 2014 and December 2020. We included patients with OHCA and nonshockable rhythms who received epinephrine during resuscitation.

Impulsivity behaviors and white matter mediate the relationship between genetic risk for cannabis use disorder and early cannabis use in adolescents.

Background And Aim: Cannabis use disorder (CUD) is strongly influenced by genetic factors; however the mechanisms underpinning this association are not well understood. This study investigated whether a polygenic risk score (PRS) based on a genome-wide association study for CUD in adults predicts cannabis use in adolescents and whether the association can be explained by inter-individual variation in structural properties of brain white matter or risk-taking behaviors.

Design And Setting: Longitudinal and cross-sectional analyses using data from the IMAGEN cohort, a European longitudinal study integrating genetic, neuroimaging and behavioral measures.

Genotyping as Part of Routine Clinical Care-The Outcomes for a Large Paediatric Vascular Anomaly Cohort.

We describe the phenotypic and genotypic spectrum of patients with vascular anomaly (VA) in a paediatric multi-disciplinary VA clinic. We measured the clinical utility of genotyping by comparing pre and posttest diagnosis and management. A 46-month retrospective analysis occurred for 250 patients offered genetic testing in the VA clinic.

Structural basis for TIR domain-mediated innate immune signaling by Toll-like receptor adaptors TRIF and TRAM.

Innate immunity relies on Toll-like receptors (TLRs) to detect pathogen-associated molecular patterns. The TIR (Toll/interleukin-1 receptor) domain-containing TLR adaptors TRIF (TIR domain-containing adaptor-inducing interferon-β) and TRAM (TRIF-related adaptor molecule) are essential for MyD88-independent TLR signaling. However, the structural basis of TRIF and TRAM TIR domain-based signaling remains unclear.
