Forest carbon sequestration on the west coast, USA: Role of species, productivity, and stockability.

Forest ecosystems store large amounts of carbon and can be important sources, or sinks, of the atmospheric carbon dioxide that is contributing to global warming. Understanding the carbon storage potential of different forests and their response to management and disturbance events are fundamental to developing policies and scenarios to partially offset greenhouse gas emissions. Projections of live tree carbon accumulation are handled differently in different models, with inconsistent results.

Comparison of clinical outcomes between active and permissive blood pressure management in extremely preterm infants.

Background: There remains uncertainty about the definition of normal blood pressure (BP), and when to initiate treatment for hypotension for extremely preterm infants. To determine the short-term outcomes of extremely preterm infants managed by active compared with permissive BP support regimens during the first 72 hours of life.

Method: This is a retrospective medical records review of 23 -28 weeks' gestational age (GA) infants admitted to neonatal units (NNU) with active BP support (aimed to maintain mean arterial BP (MABP) >30 mmHg irrespective of the GA) and permissive BP support (used medication only when babies developed signs of hypotension) regimens.

Biliary Adverse Events During Neoadjuvant Therapy for Pancreatic Cancer.

Objective: To describe a high-volume experience with biliary drainage before neoadjuvant therapy (NAT) for patients with operable pancreatic cancer (PC) and characterize the association between biliary adverse events (BAEs) and patient outcome.

Background: Patients with PC presenting with biliary obstruction require durable decompression before NAT.

Methods: Patients with operable PC and tumor-associated biliary obstruction were examined and grouped by the presence or absence of a BAE during NAT.

Neoadjuvant chemotherapy for pancreatic cancer: Quality over quantity.

Background And Objectives: The ideal duration of neoadjuvant chemotherapy (NACT) in patients with localized pancreatic adenocarcinoma (PDAC) treated with curative intent is unclear. We sought to determine the prognostic significance of both duration of NACT and Carbohydrate Antigen 19-9 (CA19-9) normalization to NACT.

Methods: We examined patients with resectable and borderline resectable PDAC treated with NACT and chemoradiation.

The incidence of new mental health disorders after acute pancreatitis: A large, propensity-matched, observational study.

Introduction: The prevalence of acute pancreatitis (AP) and mental health disorders (MHDs) are rising. While the association between chronic pancreatitis (CP) and MHDs is established, it is unknown whether there is a risk of MHDs after an index episode of AP. The aim of this study was to evaluate the incidence of MHDs and pharmacotherapy use after an episode of AP.
