Review Case ReportsLife after acute fibrinous and organizing pneumonia: a case report of a patient 30 months after diagnosis and review of the literature.
Acute fibrinous and organizing pneumonia (AFOP) is a rare histologic interstitial pneumonia pattern recently described in the literature with fewer than 120 cases published. AFOP is often difficult to diagnose and may be mistaken for other pulmonary disorders such as interstitial pneumonias or pneumonitides. Patients often present with vague symptoms of cough, dyspnea, hemoptysis, fatigue, and occasionally respiratory failure. ⋯ We will describe the presentation, diagnosis, and post-discharge course, and review the current literature. There are only 4 cases which have reported the patients' course of disease after 1 year, the longest being 2 years. To our knowledge, this is the only case of AFOP in the literature that describes the course of a patient more than 2 years after the diagnosis of AFOP, and is the most comprehensive review of the current literature.

ReviewDevelopment of a fluid resuscitation protocol using inferior vena cava and lung ultrasound.
Appropriate fluid resuscitation has been a major focus of critical care medicine since its inception. Currently, the most accurate method to guide fluid administration decisions uses "dynamic" measures that estimate the change in cardiac output that would occur in response to a fluid bolus. Unfortunately, their use remains limited due to required technical expertise, costly equipment, or applicability in only a subset of patients. ⋯ Common POCUS applications that serve as guides to fluid administration rely on assessments of the inferior vena cava to estimate preload and lung ultrasound to identify the early presence of extravascular lung water and avoid fluid overresuscitation. Although application of these POCUS measures has multiple limitations that are commonly misunderstood, current evidence suggests that they can be used in combination to sort patients among 3 fluid management categories: (1) fluid resuscitate, (2) fluid test, and (3) fluid restrict. This article reviews the pertinent literature describing the use of inferior vena cava and lung ultrasound for fluid responsiveness and presents an evidence-informed algorithm using these measures to guide fluid resuscitation decisions in the critically ill.

Randomized Controlled TrialEffect of omega-3 on hepatic regeneration in adult living donors undergoing hepatic resections for liver transplantation: A randomized controlled trial.
Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) have been shown to improve liver regeneration in experimental models. Aim was to evaluate the effects of ω-3 PUFAs on hepatic regeneration in adult living donors undergoing partial hepatectomy for liver transplantation (LDLT). ⋯ Omega-3 polyunsaturated fatty acids effectively promoted liver regeneration and functional recovery following portal hypertension in the setting of LDLT.

ReviewRecent knowledge on the pathophysiology of septic acute kidney injury: A narrative review.
Sepsis is the commonest cause of acute kidney injury in critically ill patients. Its pathophysiology is complex and not well understood. ⋯ We now know that its mechanisms included the following: (1) renal macrocirculatory and microcirculatory disturbance, (2) surge of inflammatory markers and oxidative stress, (3) coagulation cascade activation, and (4) bioenergetics adaptive response with controlled cell-cycle arrest aiming to prevent cell death. Uncovering these complicated mechanisms may facilitate the development of more appropriate therapeutic measures in the future.

Observational StudyEarly alterations in platelet mitochondrial function are associated with survival and organ failure in patients with septic shock.
The objective of the study is to determine if changes in platelet mitochondrial function in patients with sepsis are present early after presentation and the association of these changes with clinical outcomes and systemic metabolic function. ⋯ Differences in platelet mitochondrial function between survivors and nonsurvivors are present very early in the hospital course and are associated with organ failure and lactate.
