Objective: Patients with major depressive disorder (MDD) often face poor health outcomes. Additionally, patients with multiple hospitalizations tend to have worse predicted disease prognosis. Antidepressant medications remain a first-line treatment option for MDD, but data evaluating the effects of different antidepressants on psychiatric readmission rates is lacking.

Objective: This study assesses whether longitudinal quantitative pupillometry predicts neurological deterioration after large middle cerebral artery (MCA) stroke and determines how early changes are detectable.

Methods: This prospective, single-center observational cohort study included patients with large MCA stroke admitted to Boston Medical Center's intensive care unit (2019-2024). Associations between time-to-neurologic deterioration and quantitative pupillometry, including Neurological Pupil Index (NPi), were assessed using Cox proportional hazards models with time-dependent covariates adjusted for age, sex, and Alberta Stroke Program Early CT Score.

Article Synopsis
  • The management of blunt splenic trauma differs between children and adults, influenced by guidelines from organizations like the APSA and WTA, particularly regarding treatment methods like splenectomy and angioembolization.* -
  • A comparison of the 2023 guidelines revealed that while initial resuscitation is standard, the management strategies diverge: adults' care is guided by both CT findings and hemodynamic status, while children's care relies solely on hemodynamics.* -
  • Differences in ICU admission, follow-up protocols, and thromoprophylaxis use highlight the distinct approaches for each age group, suggesting a need for unified guidelines that cater to the specific needs of both children and adults.*

Background: Minimally invasive surgical necrosectomy plays an important role in the management of infected pancreatic necrosis, with a goal of removing debris and debriding necrotic tissue. Pulse lavage is designed to simultaneously hydrostatically debride and remove the infected necrotic tissue with suction. It is also able to remove significant amounts of debris without traumatic manipulation of the necrotic tissue which may be adherent to surrounding tissue and can result in injury.

Importance: Fever is associated with worse outcomes in patients with stroke, but whether preventing fever improves outcomes is unclear.

Objective: To determine whether fever prevention after acute vascular brain injury is achievable and impacts functional outcome.

Design, Setting, And Participants: Open-label randomized clinical trial with blinded outcome assessment that enrolled 686 of 1176 planned critically ill patients with stroke at 43 intensive care units in 7 countries from March 2017 to April 2021 (last date of follow-up was May 12, 2022).

Background And Purpose: Animal studies have suggested that valproic acid (VPA) is neuroprotective in aneurysmal subarachnoid hemorrhage (SAH). Potential mechanisms include an effect on cortical spreading depolarizations (CSD), apoptosis, blood-brain barrier integrity, and inflammatory pathways. However, the effect of VPA on SAH outcomes in humans has not been investigated.

Aim: Magnetic Resonance Imaging (MRI) is an important prognostic tool in cardiac arrest (CA) survivors given its sensitivity for detecting hypoxic-ischemic brain injury (HIBI), however, it is limited by poorly defined objective thresholds. To address this limitation, we evaluated a qualitative MRI score for predicting neurological outcome in CA survivors.

Methods: Adult comatose CA survivors who underwent MRI were retrospectively identified at a single academic medical center.

Study Objective: Temperature control trials in cardiac arrest patients have not reliably conferred neuroprotective benefit but have been limited by inconsistent treatment parameters. To evaluate the presence of a time dependent treatment effect, we assessed the association between preinduction time and clinical outcomes.

Methods: In this retrospective, single academic center study between 2014 and 2022, consecutive out-of-hospital cardiac arrest (OHCA) patients treated with temperature control were identified.

Background: Life-threatening, space-occupying mass effect due to cerebral edema and/or hemorrhagic transformation is an early complication of patients with middle cerebral artery stroke. Little is known about longitudinal trajectories of laboratory and vital signs leading up to radiographic and clinical deterioration related to this mass effect.

Methods: We curated a retrospective data set of 635 patients with large middle cerebral artery stroke totaling 95,463 data points for 10 longitudinal covariates and 40 time-independent covariates.

Comparative measurements of four cultivars were undertaken to assess assimilation tolerance to the high growth temperatures currently pervading Australian and other wine growing regions. The cultivars, cvs. Chardonnay, Merlot, Semillon, and Shiraz, were all grown in common growth conditions, and an hypothesis promulgated genotypic variation in assimilation and in the leaf temperature dependency.

Background: The Center for Medicare and Medicaid Services requires Organ Procurement Organizations (OPOs) to verify and document that any potential organ donor has been pronounced dead per applicable legal requirements of local, state, and federal laws. However, OPO practices regarding death by neurologic criteria (DNC) verification are not standardized, and little is known about their DNC verification processes. This study aimed to explore OPO practices regarding DNC verification in the United States.

Decommissioning consequences of offshore oil and gas infrastructure removal on marine population dynamics, including connectivity, are not well understood. We modelled the connectivity and metapopulation dynamics of three fish and two benthic invertebrate species inhabiting the natural rocky reefs and offshore oil and gas infrastructure located in the Bass Strait, south-east Australia. Using a network approach, we found that platforms are not major sources, destinations, or stepping-stones for most species, yet act as modest sources for connectivity of Corynactis australis (jewel anemone).

Article Synopsis
  • Space occupying cerebral edema is a serious complication after large ischemic strokes, particularly with middle cerebral artery (MCA) occlusion, affecting about 30% of patients and peaking 2-4 days post-injury.
  • This study analyzed data from patients with midline shift (MLS) to determine the impact of when edema peaks—acute (<48 hours), average (48-96 hours), and subacute (>96 hours)—on patient discharge outcomes.
  • Results showed that patients with subacute peak edema had better odds of favorable discharge compared to those with earlier edema peaks, indicating that timing of edema may influence treatment strategies and recovery expectations.

Introduction: Studies indicate that long-acting injectable antipsychotics (LAIAs) reduce the risk of relapse and hospitalization compared with oral antipsychotics (APs) in adults. Oral formulations of APs are well-studied in the pediatric population, but little is known regarding the off-label use of LAIAs in this population.

Methods: This retrospective chart review evaluated readmission rates for pediatric patients admitted to a psychiatric ward in a large academic hospital between January 1, 2015, and December 1, 2022, requiring AP therapy.
