A comprehensive analysis of serotype-specific invasive capacity, clinical presentations, and mortality trends of invasive pneumococcal disease.

Background: Pneumococcal conjugate vaccines (PCV) reduced invasive disease, but the overall prevalence of pneumococcal nasopharyngeal colonization among children has not changed significantly. Our knowledge of which serotypes, once colonized, hold a higher likelihood to cause invasive disease is limited.

Methods: Serotype-specific invasive capacity (IC) of Streptococcus pneumoniae was estimated using an enhanced population-based invasive pneumococcal disease (IPD) surveillance in children <7 years of age in Massachusetts and surveillance of nasopharyngeal (NP) colonization in selected Massachusetts communities in corresponding respiratory seasons.

Prevention of Infections Among Pediatric Solid Organ Transplant Recipients With Asplenia or Hyposplenism.

Pediatric solid organ transplant (SOT) recipients with splenic dysfunction are at increased risk for infections, and tailored guidance on the management of asplenia/hyposplenism among SOT recipients is often lacking. The purpose of this article is to provide practice recommendations via a frequently asked questions (FAQs) format that focuses on three main domains: the identification of asplenia/hyposplenism among SOT recipients/candidates, prophylactic strategies for mitigating the risk of invasive disease associated with splenic dysfunction in the context of transplantation, and the provision of appropriate patient counseling on the risks associated with asplenia/hyposplenism. Answers to the FAQs are based on international expert opinion informed by practices for managing splenic dysfunction and associated data in other populations with asplenia.

Distribution of race and training-related musculoskeletal injuries by track and location in Thoroughbred and Arabian racehorses.

Background: Musculoskeletal injuries (MSI) are a major concern in the horse racing industry, often leading to career-ending outcomes. Contributing factors include conformation, limb and joint defects, hoof structure, age, and hard track surfaces.

Objectives: This study aimed to evaluate the distribution of MSI in Thoroughbred and Arabian racehorses during racing and training, categorised by breed and track surface.

A Phase 1 randomized trial of homologous and heterologous filovirus vaccines with a late booster dose.

Filoviruses, including Ebola, Marburg, Sudan, and Taï Forest viruses, are zoonotic pathogens that can cause severe viral hemorrhagic fever and death. Developing vaccines that provide durable, broad immunity against multiple filoviruses is a high global health priority. In this Phase 1 trial, we enrolled 60 healthy U.

Social Contact Patterns in Rural and Urban Settings, Mozambique, 2021-2022.

Few sources have reported empirical social contact data from resource-poor settings. To address this shortfall, we recruited 1,363 participants from rural and urban areas of Mozambique during the COVID-19 pandemic, determining age, sex, and relation to the contact for each person. Participants reported a mean of 8.

Experimental and computational investigations of RNA duplexes containing N7-regioisomers of adenosine and LNA-adenosine.

Although glycosidic bonds in purines typically involve the N9 position, the chemical synthesis of adenosine produces N7-ribofuranosyladenine (7A) as a kinetically favorable ribosylation product. Similarly, in the synthesis of LNA-adenosine (AL), a minor product, N7-LNA-adenosine (7AL), is observed. While extensive research has focused on investigating the properties of N9-regioisomers of adenosine, 7A has been largely overlooked and considered as a side-product.

Surgical outcome of meningomyelocele and short-term prognostic factors: A retrospective cohort study.

Introduction: Meningomyelocele is the most common congenital anomaly. It is associated with significant complications and can result in morbidity and mortality. The present study aims to identify short-term prognostic markers by investigating the characteristics of patients with meningomyelocele during hospitalization.

Global impact of ten-valent and 13-valent pneumococcal conjugate vaccines on invasive pneumococcal disease in all ages (the PSERENADE project): a global surveillance analysis.

Background: Pneumococcal conjugate vaccines (PCVs) that are ten-valent (PCV10) and 13-valent (PCV13) became available in 2010. We evaluated their global impact on invasive pneumococcal disease (IPD) incidence in all ages.

Methods: Serotype-specific IPD cases and population denominators were obtained directly from surveillance sites using PCV10 or PCV13 in their national immunisation programmes and with a primary series uptake of at least 50%.

Telomerase inhibition in breast cancer and breast cancer stem cells: a brief review.

Breast cancer is a major health problem, accounting for one third of all cancers in women. There is no definitive treatment for breast cancer and its incidence is increasing worldwide every year. Furthermore, breast cancer stem cells cause resistance to radiation and chemotherapy.

Evaluation of Immunoglobulin A Enzyme Immunoassays to Detect Primary Respiratory Syncytial Virus Infection in Infants and Young Children.

Background: Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory infections in children <2 years of age. Prior infection in a child is usually determined by RSV antibodies; however, in young children, persisting maternal immunoglobulin G antibodies can incorrectly indicate past RSV infection. We developed and evaluated 4 immunoglobulin A (IgA) antibody enzyme immunoassays (EIAs) with the RSV F, subgroup G (Ga or Gb proteins) or RSV lysate antigens to distinguish infection induced from persisting maternal RSV antibodies.

C19orf12 gene mutation with neuropsychiatric symptoms: a case report.

Neurodegeneration with brain iron accumulation (NBIA) is a genetic disorder characterized by iron accumulation in the basal ganglia. Patients may develop behavioral abnormalities, dementia, movement disorders, and neuropsychiatric symptoms such as emotional lability, depression, anxiety, hallucinations, impulsivity, obsessions, and hyperactivity. In this case, a 46-year-old male patient with a C19orf12 mutation experienced depressive complaints before movement disorders, followed by cognitive deficits and psychotic symptoms as the disease progressed.

Transition to Enteral Triazole Antifungal Therapy for Pediatric Invasive Candidiasis: Secondary Analysis of a Multicenter Cohort Study Conducted by the Pediatric Fungal Network.

Of 319 children with invasive candidiasis, 67 (21%) transitioned from intravenous to enteral antifungal therapy. Eight (12%) transitioned back to intravenous antifungal therapy, one due to perceived treatment failure defined by clinical progression or worsening. Global treatment response at study completion was successful in 66 participants who transitioned to enteral therapy.

C-reactive protein/albumin ratio as a novel predictor for nutritional status of geriatric patients.

Background And Aims: The C-reactive protein to albumin ratio (CAR) is a novel parameter that has been reported as a significant prognostic marker in some diseases. The purpose of the present research was to investigate the predictive value of this ratio with regard to nutritional status in geriatric patients.

Methods And Results: A total of 154 geriatric patients (age ≥65 years) who consecutively presented to the internal medicine outpatient clinic were included in this cross-sectional study.

Effects of toll like receptor 4 (TLR4) and toll like receptor 2 (TLR 2) gene polymorphisms on clinical outcomes in acute non-biliary pancreatitis patients.

Introduction: In this retrospective study, it was aimed to evaluate effects of Toll Like Receptor 4 (TLR4) and Toll Like Receptor 2 (TLR 2) gene polymorphisms on clinical outcomes in acute non-biliary pancreatitis patients.

Methods: A total of 108 acute non-biliary pancreatitis patients (ANBP) were retrospectively subjected to the study. Gender, age, number of attacks, hospitalization duration, amylase, lipase, aspartate aminotransferase (AST), alanine aminotransferase (ALT), leukocyte, C-reactive protein (CRP), total bilirubin, direct bilirubin, Atlanta score, ultrasonography (USG), Computer Tomography (CT) and patient outcome differences between TLR 4 Rs4986790, TLR 4 Rs4986791 and TLR 2 groups were evaluated.

Leveraging real-world Data from administrative claims and medical records to inform safety and effectiveness of piperacillin-tazobactam in the Management of Pediatric Hospital Acquired Pneumonia.

Pediatric-specific safety data are required during development of pharmaceutical agents. Retrospective studies can leverage real-world data to assess safety and effectiveness in children where prospective, controlled studies are not feasible. A retrospective cohort study combined data from Pediatric Health Information Systems (PHIS) and medical records to evaluate the safety and effectiveness of piperacillin/tazobactam (P/T) in pediatric patients with hospital-acquired pneumonia (HAP).

Enhancing Within-Person Estimation of Neurocognition and the Prediction of Externalizing Behaviors in Adolescents.

Decades of research document an association between neurocognitive dysfunction and externalizing behaviors, including rule-breaking, aggression, and impulsivity. However, there has been very little work that examines how multiple neurocognitive functions co-occur within individuals and which combinations of neurocognitive functions are most relevant for externalizing behaviors. Moreover, Latent Profile Analysis (LPA), a widely used method for grouping individuals in person-centered analysis, often struggles to balance the tradeoff between good model fit (splitting participants into many latent profiles) and model interpretability (using only a few, highly distinct latent profiles).

Comprehensive profiling of social mixing patterns in resource poor countries: A mixed methods research protocol.

Background: Low-and-middle-income countries (LMICs) bear a disproportionate burden of communicable diseases. Social interaction data inform infectious disease models and disease prevention strategies. The variations in demographics and contact patterns across ages, cultures, and locations significantly impact infectious disease dynamics and pathogen transmission.

Temporal segmentation and "look ahead" simulation: Physical events structure visual perception of intuitive physics.

How we perceive the physical world is not only organized in terms of objects, but also structured in time as sequences of events. This is especially evident in intuitive physics, with temporally bounded dynamics such as falling, occlusion, and bouncing demarcating the continuous flow of sensory inputs. While the spatial structure and attentional consequences of physical objects have been well-studied, much less is known about the temporal structure and attentional consequences of physical events in visual perception.
