Review Meta Analysis
The Impact of Visceral Pleural Invasion In Node-negative Non-small-cell Lung cancer: A Systematic Review and Meta-analysis.
Visceral pleural invasion (VPI) is considered an aggressive and invasive factor in non-small cell lung cancer (NSCLC). Recent studies found that depending on tumor size, VPI influences T stage, but there is no consensus on whether VPI is important in node-negative NSCLC. In addition, its role in stage IB NSCLC is still uncertain. In this meta-analysis, we assessed the role of VPI in node-negative NSCLC according to various tumor sizes and especially in stage IB disease. ⋯ VPI together with tumor size has a synergistic effect on survival in node-negative NSCLC. Patients with stage IB NSCLC and larger tumor size with VPI might be considered for adjuvant chemotherapy after surgical resection and need careful preoperative evaluation and postoperative follow-up. Further randomized clinical trials to determine the impact of adjuvant chemotherapy in patients with stage IB NSCLC with VPI are warranted.

Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal disease. Until recently, the standard therapy for this disease has been essentially supportive, with the exception of a minority of patients who were eligible for lung transplantation. The development pathway for novel medications for IPF has been complicated. ⋯ In October 2014, these two drugs became the first agents to be approved by the US Food and Drug Administration for the treatment of IPF. (Pirfenidone had already been approved in several countries outside the United States.) In November 2014, the European Medicines Agency approved the use of nintedanib for IPF. The landscape for management of IPF has markedly changed with the advent of approved therapeutic options for IPF. In this article, we review the strategies that are being used to increase the likelihood of success in clinical development programs of novel disease-modifying agents in IPF.

Randomized Controlled Trial
Response to Fluid Boluses in the Fluid and Catheter Treatment Trial.
Recent emphasis has been placed on methods to predict fluid responsiveness, but the usefulness of using fluid boluses to increase cardiac index in critically ill patients with ineffective circulation or oliguria remains unclear. ⋯ In this cohort of critically ill patients with ARDS who were previously resuscitated, the rate of fluid responsiveness was low, and fluid boluses only led to small hemodynamic changes.

Atrial fibrillation (AF) that newly occurs during critical illness presents challenges for both short- and long-term management. During critical illness, patients with new-onset AF are clinically evaluated for hemodynamic instability owing to the arrhythmia as well as for potentially reversible arrhythmia triggers. ⋯ Therefore, we suggest increased efforts to improve communication of AF events between inpatient and outpatient providers and to reassess patients who had experienced new-onset AF during critical illness after they transition to the post-ICU setting. We describe various strategies for the assessment and long-term management of patients with new-onset AF during critical illness.

Managing critically ill obstetric patients in the ICU is a challenge because of their altered physiology, different normal ranges for laboratory and clinical parameters in pregnancy, and potentially harmful effects of drugs and interventions on the fetus. About 200 to 700 women per 100,000 deliveries require ICU admission. A systematic five-step approach is recommended to enhance maternal and fetal outcomes: (1) differentiate between medical and obstetric disorders with similar manifestations, (2) identify and treat organ dysfunction, (3) assess maternal and fetal risk from continuing pregnancy and decide if delivery/termination of pregnancy will improve outcome, (4) choose an appropriate mode of delivery if necessary, and (5) optimize organ functions for safe delivery. ⋯ With more complex fetal surgical interventions being performed for congenital disorders, maternal complications are increasing. Ovarian hyperstimulation syndrome is also becoming common because of treatment of infertility with assisted reproduction techniques. Part II will deal with common medical disorders and their management in critically ill pregnant women.
