Optimal site of care for administration of extended half-life respiratory syncytial virus (RSV) antibodies to infants in the United States (US).

Introduction: New extended half-life antibodies for the single-dose prevention of medically attended (MA) respiratory syncytial virus (RSV) lower respiratory tract infection (LRTI) have been developed for administration to all infants before or during their first RSV season. For infants born during the season, administration as soon as feasible after birth would provide optimal protection and minimize access disparities. The objective of this study was to assess the time from birth hospitalization discharge to the first outpatient visit (FOV) among US infants in order to determine optimal site of administration for the extended half-life antibody.

Medically Attended Illness due to Respiratory Syncytial Virus Infection Among Infants Born in the United States Between 2016 and 2020.

Background: Respiratory syncytial virus (RSV) is a leading cause of infant hospitalization in the United States. Preterm infants and those with select comorbidities are at highest risk of RSV-related complications. However, morbidity due to RSV infection is not confined to high-risk infants.

Pseudohyperkalaemia in essential thrombocytosis: an important clinical reminder.

Summary: An 82-year-old female was admitted to a general hospital due to progressive bilateral lower limb weakness. A T8-T9 extramedullary meningioma was diagnosed by MRI, and the patient was referred for excision of the tumour. During the patient's admission, she was noted to have persistent hyperkalaemia which was refractory to treatment.

Paradoxical deterioration in seizure control due to anticonvulsant-induced hypocalcaemia.

Hepatic cytochrome P450 enzyme induction is associated with certain antiepileptic drugs (AEDs) and may result in hypocalcaemia secondary to vitamin D deficiency. We report a case of a 44-year-old man with a history of epilepsy, who presented with breakthrough seizures after having previously been seizure-free for 11 years. Investigations revealed severe hypocalcaemia with a corrected calcium of 1.

SENTINEL1: Two-Season Study of Respiratory Syncytial Virus Hospitalizations among U.S. Infants Born at 29 to 35 Weeks' Gestational Age Not Receiving Immunoprophylaxis.

Objective: The SENTINEL1 observational study characterized confirmed respiratory syncytial virus hospitalizations (RSVH) among U.S. preterm infants born at 29 to 35 weeks' gestational age (wGA) not receiving respiratory syncytial virus (RSV) immunoprophylaxis (IP) during the 2014 to 2015 and 2015 to 2016 RSV seasons.

Identification of an p.Gly292fs Frameshift Mutation Presenting as Diabetes During Pregnancy in a Maltese Family.

The diagnosis of maturity onset diabetes of the young (MODY) is a challenging process in view of the extensive clinical and genetic heterogeneity of the disease. Mutations in the gene encoding hepatocyte nuclear factor 1α () are responsible for most forms of monogenic diabetes in Northern European populations. Genetic analysis through a combination of whole exome sequencing and Sanger sequencing in three Maltese siblings and their father identified a rare duplication/frameshift mutation in exon 4 of that lies within a known mutational hotspot in this gene.

Primary Bilateral Non-Hodgkin's Lymphoma of the Adrenal Gland Presenting as Incidental Adrenal Masses.

Although lymphoma may occasionally involve the adrenal glands as part of a generalized disease process, primary adrenal lymphoma (PAL) is a rare disease. We present a case of a 62-year-old woman with a history of mild/moderate hereditary spherocytosis with a well-compensated baseline haemoglobin, who presented with rapidly progressive symptomatic anaemia. During the diagnostic workup, imaging revealed bilateral large adrenal masses and she was later diagnosed with diffuse large B-cell non-Hodgkin's lymphoma (DLBCL), with the adrenal glands being the dominant site of the disease.

Refractory hypocalcaemia complicating metastatic prostatic carcinoma.

A 72-year-old man with a background of ischaemic heart disease was referred to the accident and emergency department with a 1-week history of worsening dyspnoea and lethargy. A chest X-ray revealed a right-sided lobar pneumonia and a prolonged corrected QT interval was noted on his ECG at presentation. Laboratory investigations confirmed severe hypocalcaemia, significant vitamin D deficiency and relative hypoparathyroidism.

Athletic trainers have a place in interprofessional education and practice.

Athletic trainers (ATs) are healthcare providers who work in collaboration with physicians, nurses, physical therapists and others to provide care to physically active individuals. Founded in 1950, the National Athletic Trainers' Association (NATA) represents certified ATs and other individuals who support the athletic training profession. The Board of Certification (BOC) has the only accredited certification program for ATs in USA.

Transcriptome profiling of the rice blast fungus during invasive plant infection and in vitro stresses.

Background: Rice blast is the most threatening disease to cultivated rice. Magnaporthe oryzae, its causal agent, is likely to encounter environmental challenges during invasive growth in its host plants that require shifts in gene expression to establish a compatible interaction. Here, we tested the hypothesis that gene expression patterns during in planta invasive growth are similar to in vitro stress conditions, such as nutrient limitation, temperature up shift and oxidative stress, and determined which condition most closely mimicked that of in planta invasive growth.

Linking practices with community programs to improve immunization rates.

Pediatricians should be knowledgeable about programs available in their community and support efforts to collaborate with other providers, public health departments and immunization coalitions in their community. Through immunization coalitions and widespread use of an immunization registry, together with participating private providers, case management and home visitation programs can improve immunization rates among the highest risk children.

Improving immunization rates in practice settings.

Many pediatricians do not know the immunization rate of patients in their practice. Evidence-based standards of practice have been established, leading to improved rates. Quality improvement efforts aimed at immunization are effective and may lead to improvement in other preventive health services.

Maximizing office-based immunization.

Vaccines are a great public health achievement only if we can deliver those vaccines to individual patients. It is impressive that gradually increasing immunization rates are so consistent in spite of a new birth cohort every year, complexity of the schedule, shortages, changes in reimbursement policies, and vaccine news stories. Pediatricians have always embraced their public health role, especially as immunization providers.

Utility of lab-on-a-chip technology for high-throughput nucleic acid and protein analysis.

On-chip electrophoresis can provide size separations of nucleic acids and proteins similar to more traditional slab gel electrophoresis. Lab-on-a-chip (LoaC) systems utilize on-chip electrophoresis in conjunction with sizing calibration, sensitive detection schemes, and sophisticated data analysis to achieve rapid analysis times (<120 s). This work describes the utility of LoaC systems to enable and augment systems biology investigations.

CYP3A4 induction by drugs: correlation between a pregnane X receptor reporter gene assay and CYP3A4 expression in human hepatocytes.

Induction of cytochrome P450 3A4 (CYP3A4) is determined typically by employing primary culture of human hepatocytes and measuring CYP3A4 mRNA, protein and microsomal activity. Recently a pregnane X receptor (PXR) reporter gene assay was established to screen CYP3A4 inducers. To evaluate results from the PXR reporter gene assay with those from the aforementioned conventional assays, 14 drugs were evaluated for their ability to induce CYP3A4 and activate PXR.

Hepatitis C virus NS3 protease requires its NS4A cofactor peptide for optimal binding of a boronic acid inhibitor as shown by NMR.

NMR spectroscopy was used to characterize the hepatitis C virus (HCV) NS3 protease in a complex with the 24 residue peptide cofactor from NS4A and a boronic acid inhibitor, Ac-Asp-Glu-Val-Val-Pro-boroAlg-OH. Secondary-structure information, NOE constraints between protease and cofactor, and hydrogen-deuterium exchange rates revealed that the cofactor was an integral strand in the N-terminal beta-sheet of the complex as observed in X-ray crystal structures. Based upon chemical-shift perturbations, inhibitor-protein NOEs, and the protonation state of the catalytic histidine, the boronic acid inhibitor was bound in the substrate binding site as a transition state mimic.
