Peripheral Use of Vasopressors in Shock: Clinical Considerations and Recommendations for Use in Obstetrics.

Objective:  This study aimed to evaluate the safety of peripheral administration of vasopressor agents among patients with circulatory shock.

Study Design:  We reviewed the published literature evaluating the use of peripheral norepinephrine in patients with shock and proposed a protocol for use in labor and delivery units.

Results:  Peripheral administration of norepinephrine is a safe and potentially lifesaving intervention for patients in labor and delivery with extremely low complication rates.

Obstetric sepsis: Clinical pearls for diagnosis and management.

Sepsis is a leading cause of maternal morbidity and mortality worldwide. Early recognition and treatment improve outcomes. Multiple sepsis diagnostic screening tools are available and may be used in clinical practice; however, early thorough bedside evaluation of the patient is fundamental.

A deep learning anthropomorphic model observer for a detection task in PET.

Background: Lesion detection is one of the most important clinical tasks in positron emission tomography (PET) for oncology. An anthropomorphic model observer (MO) designed to replicate human observers (HOs) in a detection task is an important tool for assessing task-based image quality. The channelized Hotelling observer (CHO) has been the most popular anthropomorphic MO.

Maternal and Neonatal Outcomes of Gunshot Wounds in Pregnancy: A Systematic Review of Case Reports.

A systematic review was performed to compare adverse maternal and neonatal outcomes among pregnant patients with gunshot wounds (GSW) to the abdominopelvic vs other region(s) at 20 weeks gestation. A search of Medline Ovid, Elsevier Embase, EBSCO CINAHL, and Cochrane Library in July 2022 and reference searches resulted in 1742 studies, which were screened. The 41 included studies reported outcomes for 59 pregnant patients with GSW, of which 31 (52.
