Human babesiosis is a potentially fatal tick-borne disease caused by intraerythrocytic Babesia parasites. The emergence of resistance to recommended therapies highlights the need for new and more effective treatments. Here we demonstrate that the 8-aminoquinoline antimalarial drug tafenoquine inhibits the growth of different Babesia species in vitro, is highly effective against Babesia microti and Babesia duncani in mice and protects animals from lethal infection caused by atovaquone-sensitive and -resistant B.

Effective and safe therapies for the treatment of diseases caused by intraerythrocytic parasites are impeded by the rapid emergence of drug resistance and the lack of novel drug targets. One such disease is human babesiosis, which is a rapidly emerging tick-borne illness caused by Babesia parasites. In this study, we identified fosinopril, a phosphonate-containing, FDA-approved angiotensin converting enzyme (ACE) inhibitor commonly used as a prodrug for hypertension and heart failure, as a potent inhibitor of Babesia duncani parasite development within human erythrocytes.

Technological advancements and rapid expansion in the clinical use of extracorporeal life support (ECLS) across all age ranges in the last decade, including during the COVID-19 pandemic, has led to important ethical considerations. As a costly and resource intensive therapy, ECLS is used emergently under high stakes circumstances where there is often prognostic uncertainty and risk for serious complications. To develop a research agenda to further characterize and address these ethical dilemmas, a working group of specialists in ECLS, critical care, cardiothoracic surgery, palliative care, and bioethics convened at a single pediatric academic institution over the course of 18 months.

Cerebral arterial gas embolism (CAGE) is a rare but serious cause for acute neurologic deficit that occurs most often in divers who breathe compressed gas at depth or iatrogenically from a variety of invasive medical procedures. We present a rare case of CAGE caused by inhaling helium from an unregulated, high-pressure gas cylinder. Following inhalation, the patient experienced loss of consciousness, neurologic deficits, pneumomediastinum, and pneumothorax requiring transfer and treatment at a hyperbaric facility with resulting resolution of neurologic symptoms.

The objective of this article was to identify demographic and clinical factors associated with early recurrent arrest (RA; <48 hours) and late RA (≥48 hours) among pediatric inpatients following an initial in-hospital cardiac arrest. A retrospective cohort study of inpatients was performed in a free-standing academic quaternary care children's hospital. All inpatients were <18 years old with a cardiac arrest event requiring ≥1 minute of cardiopulmonary resuscitation with the return of spontaneous circulation sustained for ≥20 minutes at Seattle Children's Hospital from February 1, 2012, to September 18, 2019.

Recovery following pediatric critical illness is multifaceted and complex. While most critically ill children survive, many experience morbidities in physical, emotional, cognitive, and social function. We aimed to deeply explore and describe the multidimensional impact of pediatric septic shock for affected children and their families at the granular level using exploratory qualitative methodology.

Background: Exercise increases intra-abdominal pressure (IAP) acutely, which may impact the pelvic floor of women. IAP during exercise demonstrates high variability among women but is not routinely assessed. Assessing less invasive measures related to IAP during exercise may facilitate study of how IAP impacts the pelvic floor.

Purpose: The aim of this study was to evaluate outcomes of pediatric intensive care unit (PICU) patients with delirium treated with haloperidol or quetiapine compared with propensity-matched, untreated patients.

Materials And Methods: A single-center retrospective cohort study was conducted including PICU admissions of ≥ 48 h for children ≥ 2 months old with a positive delirium screening score (Cornell Assessment of Pediatric Delirium ≥ 9). We generated propensity scores for the likelihood of receiving treatment with haloperidol or quetiapine using logistic regression, and matched untreated to treated patients 2:1 to compare outcomes between groups.

Patients on extracorporeal life support (ECLS) are at risk for central nervous system (CNS) injury. One potentially modifiable risk factor is site of arterial cannulation in venoarterial (VA) ECLS, as in most cases one can choose the femoral or carotid artery. There is acute alteration in cerebral blood flow with carotid cannulation, potentially increasing the risk of stroke.

Objectives: High intra-abdominal pressure (IAP) may influence the development of pelvic floor disorders. We and others have used intravaginal pressure transducers to measure IAP in women during exercise and daily activities, but utilizing the transducer for long-term measurements creates compliance issues. Waist-worn accelerometers are prominent in research and may be a reliable alternative for approximating IAP.

Intra-abdominal pressure may be one of the few modifiable risk factors associated with developing a pelvic floor disorder. With one in eight women having surgery to correct a pelvic floor disorder in their lifetimes, intra-abdominal pressure may be a key to understanding the disease etiology and how to mitigate its occurrence and progression. Many traditional methods of intra-abdominal pressure measurement have limitations in data quality, environment of use, and patient comfort.

Objective: End-tidal carbon dioxide (ETCO(2)) measurements during cardiopulmonary resuscitation (CPR) reflect variable cardiac output over time, and low values have been associated with decreased survival. The goals of this review are to confirm and quantify this relationship and to determine the mean ETCO(2) value among patients with return of spontaneous circulation (ROSC) as an initial step toward determining an appropriate target for intervention during resuscitation in the absence of prospective data.

Data Sources And Study Selection: The PubMed database was searched for the key words "end-tidal carbon dioxide" or "capnometry" or "capnography" and "resuscitation" or "return of spontaneous circulation.
