Στην βιολογία, το περιβάλλον μπορεί να καθοριστεί σαν ενα σύνολο κλιματικών, βιοτικών, κοινωνικών και εδαφικών παραγόντων που δρουν σε έναν οργανισμό και καθορίζουν την ανάπτυξη και την επιβίωση του. Έτσι, περιλαμβάνει οτιδήποτε μπορεί να επηρεάσει άμεσα τον μεταβολισμό ή τη συμπεριφορά των ζωντανών οργανισμών ή ειδών, όπως το φως, ο αέρας, το νερό, το έδαφος και άλλοι παράγοντες.

Στην αρχιτεκτονική, την εργονομία και την ασφάλεια στην εργασία, περιβάλλον είναι το σύνολο των χαρακτηριστικών ενός δωματίου ή κτιρίου που επηρεάζουν την ποιότητα ζωής και την αποδοτικότητα, περιλαμβανομένων των διαστάσεων και της διαρρύθμισης των χώρων διαβίωσης και της επίπλωσης, του φωτισμού, του αερισμού, της θερμοκρασίας, του θορύβου κλπ. Επίσης μπορεί να αναφέρεται στο σύνολο των δομικών κατασκευών. Δείτε επίσης το άρθρο για το δομημένο περιβάλλον.
Στην ψυχολογία, περιβαλλοντισμός είναι η θεωρία ότι το περιβάλλον (με τη γενική και κοινωνική έννοια) παίζει μεγαλύτερο ρόλο από την κληρονομικότητα καθορίζοντας την ανάπτυξη ενός ατόμου. Συγκεκριμένα, το περιβάλλον είναι ένας σημαντικός παράγοντας πολλών ψυχολογικών θεωριών.
Στην τέχνη, το περιβάλλον αποτελεί κινητήριο μοχλό και μούσα εμπνέοντας τους ζωγράφους ή τους ποιητές. Σε όλες τις μορφές της Τέχνης αποτελεί έμπνευση και οι Καλές Τέχνες φανερώνουν την επιρροή οπού άσκησε σε όλους τους καλλιτέχνες με όποιο είδος Τέχνης κι αν ασχολούνται. Ο άνθρωπος μέσα στο περιβάλλον δημιουργεί Μουσική, Ζωγραφική, Ποίηση, Γλυπτική, χορό, τραγούδι, θέατρο, αλλά και όλες οι μορφές τέχνης έχουν άμεση έμπνευση από το περιβάλλον.

Outcomes of Cancer Patients Discharged From ICU After a Decision to Forgo Life-Sustaining Therapies
Objectives: Many cancer patients are admitted to an ICU and decisions to forgo life-sustaining therapies are frequent during ICU stay. A significant proportion of these patients are subsequently discharged from ICU, but their outcomes are unknown. Design: Retrospective. Setting: ICU of oncological hospital. Patients: Adult cancer patients admitted to ICU, then with a decision to forgo life-sustaining therapies and that were discharged from ICU. Interventions: None. Measurements...

Prognostic Value of Glial Fibrillary Acidic Protein in Patients With Moderate and Severe Traumatic Brain Injury: A Systematic Review and Meta-Analysis
Objectives: Biomarkers have been suggested as potential prognostic predictors following a moderate or severe traumatic brain injury but their prognostic accuracy is still uncertain. The objective of this systematic review is to assess the ability of the glial fibrillary acidic protein to predict prognosis in patients with moderate or severe traumatic brain injury. Data Sources: MEDLINE, Embase, CENTRAL, and BIOSIS electronic databases and conference abstracts, bibliographies of selected studies,...

Effect of Documenting Prognosis on the Information Provided to ICU Proxies: A Randomized Trial
Objectives: The Critical Care Choosing Wisely Task Force recommends that intensivists offer patients at high risk for death or severe functional impairment the option of pursuing care focused on comfort. We tested the a priori hypothesis that intensivists who are prompted to document patient prognosis are more likely to disclose prognosis and offer comfort-focused care. Design: Randomized controlled trial (clinicaltrials.gov: NCT02721810). Setting: High-fidelity Simulation Center in...

Transfusion-Associated Circulatory Overload in ICUs: A Scoping Review of Incidence, Risk Factors, and Outcomes
Transfusion-associated circulatory overload is the most frequent serious adverse transfusion reaction, with an incidence close to 1% of transfused patients in the general adult population. Patients in ICUs are probably more at risk of transfusion-associated circulatory overload as they are more frequently transfused and associated with more comorbidities. However, the epidemiology of transfusion-associated circulatory overload in ICU is not well characterized, leading to a risk of underdiagnosis. ...

Effect of Neurally Adjusted Ventilatory Assist on Patient-Ventilator Interaction in Mechanically Ventilated Adults: A Systematic Review and Meta-Analysis
Objectives: Patient-ventilator asynchrony is common among critically ill patients undergoing mechanical ventilation and has been associated with adverse outcomes. Neurally adjusted ventilatory assist is a ventilatory mode that may lead to improved patient-ventilator synchrony. We conducted a systematic review to determine the impact of neurally adjusted ventilatory assist on patient-ventilator asynchrony, other physiologic variables, and clinical outcomes in adult patients undergoing invasive...

Comparison of Two Techniques to Measure Optic Nerve Sheath Diameter in Patients at Risk for Increased Intracranial Pressure
Objectives: Intracranial pressure over 20 mm Hg is associated with poor neurologic prognosis, but measuring intracranial pressure directly requires an invasive procedure. Dilation of the optic nerve sheath on axial ultrasound of the eye has been correlated with elevated intracranial pressure, but optimal cutoffs have been inconsistent possibly related to the measurement technique. A coronal technique has been studied on healthy volunteers but not on patients with high intracranial pressure. We...

Acute Kidney Stress and Prevention of Acute Kidney Injury
Critical care physicians continue to be challenged to recognize an environment that has the potential to result in acute kidney injury, with its associated short- and long-term consequences. The recent development of cell cycle arrest biomarkers that signal the potential development of acute kidney injury is part of an evolution in the molecular diagnosis and understanding of acute kidney injury. A preinjury phase that may lead to acute kidney injury has been described as "acute kidney stress." This...

Moderate-Intensity Insulin Therapy Is Associated With Reduced Length of Stay in Critically Ill Patients With Diabetic Ketoacidosis and Hyperosmolar Hyperglycemic State
Objectives: Insulin infusion therapy is commonly used in the hospital setting to manage diabetic ketoacidosis and hyperosmolar hyperglycemic state. Clinical evidence suggests both hypoglycemia and glycemic variability negatively impact patient outcomes. The hypothesis of this study was that moderate-intensity insulin therapy decreases hospital length of stay and prevalence of hypoglycemia in patients with diabetic ketoacidosis and hyperosmolar hyperglycemic state. Design: Pre-post study. ...
