[Interpretation of the clinical guideline for point-of-care ultrasonography in the neonatal intensive care unit in the United States].

In December 2022, the American Academy of Pediatrics released a clinical guideline for point-of-care ultrasonography (POCUS) in the neonatal intensive care unit (NICU). The guideline outlined the development and current status of POCUS in the NICU, and summarized the key elements and implementation guidelines for successful implementation of POCUS in the NICU. This article provides an overview of the key points of the clinical guideline and analyzes the current status of POCUS in China, providing a reference for the implementation of POCUS in neonatal care in China.

Use of Point-of-Care Ultrasonography in the NICU for Diagnostic and Procedural Purposes.

Point-of-care ultrasonography (POCUS) refers to the use of portable imaging performed by the provider clinician at the bedside for diagnostic, therapeutic, and procedural purposes. POCUS could be considered an extension of the physical examination but not a substitute for diagnostic imaging. Use of POCUS in emergency situations can be lifesaving in the NICU if performed in a timely fashion for cardiac tamponade, pleural effusions, pneumothorax, etc, with potential for enhancing quality of care and improving outcomes.

Impact of remote prenatal education on program participation and breastfeeding of women in rural and remote Indigenous communities.

Background: First Nations (FN) women have a higher risk of diabetes than non-FN women in Canada. Prenatal education and breastfeeding may reduce the risk of diabetes in mothers and offspring. The rates of breastfeeding initiation and participation in the prenatal program are low in FN communities.

Do soft anions promote protein denaturation through binding interactions? A case study using ribonuclease A.

It has long been known that large soft anions like bromide, iodide and thiocyanate are protein denaturing agents, but their mechanism of action is still unclear. In this work we have investigated the protein denaturing properties of these anions using Ribonuclease A (RNase A) as a model protein system. Salt-induced perturbations to the protein folding free energy were determined using differential scanning calorimetry and the results demonstrate that the addition of sodium iodide and sodium thiocyanate significantly decreases the melting temperature of the protein.

Antibacterial Potential of 2.5% Sodium Hypochlorite in Distinct Irrigation Protocols on Enterococcus faecalis Biofilm.

Objective: The aim of this study was to evaluate the effect of irrigation methods on antibacterial potential of 2.5% NaOCl on Enterococcus faecalis biofilm.

Materials And Methods: Enterococcus faecalis biofilms were prepared during 60 days on 48 human root canals and randomized into control and experimental groups using positive and negative pressure irrigation.

Identification of three novel FGF16 mutations in X-linked recessive fusion of the fourth and fifth metacarpals and possible correlation with heart disease.

Nonsense mutations in FGF16 have recently been linked to X-linked recessive hand malformations with fusion between the fourth and the fifth metacarpals and hypoplasia of the fifth digit (MF4; MIM#309630). The purpose of this study was to perform careful clinical phenotyping and to define molecular mechanisms behind X-linked recessive MF4 in three unrelated families. We performed whole-exome sequencing, and identified three novel mutations in FGF16.

Telithromycin in the treatment of acute bacterial sinusitis, acute exacerbations of chronic bronchitis, and community-acquired pneumonia.

Acute bacterial sinusitis (ABS), acute exacerbations of chronic bronchitis (AECB), and community-acquired pneumonia (CAP) are common conditions and constitute a substantial socioeconomic burden. The ketolides are a new class of antibacterials with a targeted spectrum of antibacterial activity. In vitro, telithromycin is active against common bacterial pathogens that cause upper and lower respiratory tract infections, including some isolates that are resistant to other antibiotic classes.
