SARS-CoV-2 Variants May Affect Saliva RT-PCR Assay Sensitivity.

Background: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants demonstrate predilection for different regions of the respiratory tract. While saliva-based reverse transcription-polymerase chain reaction (RT-PCR) testing is a convenient, cost-effective alternative to nasopharyngeal swabs (NPS), few studies to date have investigated whether saliva sensitivity differs across variants of concern.

Methods: SARS-CoV-2 RT-PCR was performed on paired NPS and saliva specimens collected from individuals with acute coronavirus disease 2019 (COVID-19) symptoms or exposure to a COVID-19 household contact.

Challenges in Assessment and Management of Postoperative Agitation and Delirium in a Stroke Patient with Limited English Proficiency: Case Report.

While Title VI of the Civil Rights Act of 1964 mandates use of interpreters for patients with limited English proficiency, significant disparities persist in intensive postsurgical care. We present the case of a 60-year-old Vietnamese-speaking man with a Type A aortic dissection requiring postoperative mechanical ventilation and stroke care. Despite use of a remote video interpreter, our language-discordant nursing and physician providers faced challenges in managing agitation and delirium and assessing neurological function.

Detection of SARS-CoV-2-Specific Secretory IgA and Neutralizing Antibodies in the Nasal Secretions of Exposed Seronegative Individuals.

Mucosal immunity may contribute to clearing SARS-CoV-2 infection prior to systemic infection, thereby allowing hosts to remain seronegative. We describe the meaningful detection of SARS-CoV-2-specific nasal mucosal antibodies in a group of exposed-household individuals that evaded systemic infection. Between June 2020 and February 2023, nasopharyngeal swab (NPS) and acute and convalescent blood were collected from individuals exposed to a SARS-CoV-2-confirmed household member.

Safety of Nebulized Ciprodex for Postoperative Management of Tracheal Resection.

Objective: Anastomotic complications after tracheal resection/cricotracheal resection (TR/CTR), such as granulation tissue formation, can lead to severe morbidity. The off-label use of nebulized ciprofloxacin-dexamethasone (Ciprodex) for granulation tissue prophylaxis has anecdotally been used after TR/CTR, especially in pediatric patients. However, its use in the adult population, and its safety and side effect profile post-TR/CTR has not been reported.

Cerebrovascular responses to a 90° tilt in healthy neonates.

Background: Tilts can induce alterations in cerebral hemodynamics in healthy neonates, but prior studies have only examined systemic parameters or used small tilt angles (<90°). The healthy neonatal population, however, are commonly subjected to large tilt angles (≥90°). We sought to characterize the cerebrovascular response to a 90° tilt in healthy term neonates.

Risk factors for unanticipated hospitalizations in children and youth with spina bifida at an urban children's hospital: A cross-sectional study.

Background: Spina bifida (SB) is a condition resulting from the improper closure of the neural tube and vertebral column during fetal development. While patients' life expectancy and quality of life have improved dramatically due to medical advances, children continue to experience health-related issues that often require hospitalizations.

Objective: The association among sociodemographic and clinical characteristics with potentially preventable hospitalizations (PPH) in children and youth with myelomeningocele type SB was investigated in this cross-sectional study.
