Article Synopsis
  • The COVID-19 pandemic underscored the significance of social determinants of health, particularly highlighting the impact of social networks on health outcomes during periods of social isolation due to distancing measures.
  • A retrospective study analyzed data from 208 COVID-19 pneumonia survivors in New York City, focusing on the relationship between social networks and both self-rated health changes and physical function.
  • The findings revealed that improved social networks positively influenced health outcomes, with a higher Social Network Score linked to better self-rated health and physical function, suggesting that strengthening social connections could aid recovery from COVID-19 and other acute illnesses.

Context: Efforts to reduce the psychological distress of surrogate decision-makers of critically ill patients have had limited success, and some have even exacerbated distress.

Objectives: The aim of this study was to determine the feasibility, acceptability, and preliminary efficacy of EMPOWER (Enhancing and Mobilizing the POtential for Wellness and Resilience), an ultra-brief (∼2-hour), 6-module manualized psychological intervention for surrogates.

Methods: Surrogates who reported significant anxiety and/or an emotionally close relationship with the patient (n=60) were randomized to receive EMPOWER or enhanced usual care (EUC) at one of three metropolitan hospitals.

Inflammation can trigger lasting phenotypes in immune and non-immune cells. Whether and how human infections and associated inflammation can form innate immune memory in hematopoietic stem and progenitor cells (HSPC) has remained unclear. We found that circulating HSPC, enriched from peripheral blood, captured the diversity of bone marrow HSPC, enabling investigation of their epigenomic reprogramming following coronavirus disease 2019 (COVID-19).

Background: Critical care trainees were integral in the coronavirus disease (COVID-19) pandemic response. Several perspective pieces have provided insight into the pandemic's impact on critical care training. Surveys of program directors and critical care trainees have focused on curricular impact.

Vascular injury is a well-established, disease-modifying factor in acute respiratory distress syndrome (ARDS) pathogenesis. Recently, coronavirus disease 2019 (COVID-19)-induced injury to the vascular compartment has been linked to complement activation, microvascular thrombosis, and dysregulated immune responses. This study sought to assess whether aberrant vascular activation in this prothrombotic context was associated with the induction of necroptotic vascular cell death.

Little is known about end-of-life intensive care provided to patients with intellectual disabilities (ID). To identify differences in receipt of end-of-life cardiopulmonary resuscitation (CPR) and endotracheal intubation among adult patients with and without ID and examine whether do-not-resuscitate orders (DNRs) mediate associations between ID and CPR. Exploratory matched cohort study using medical records of inpatient decedents treated between 2012 and 2018.

The coronavirus disease (COVID-19) pandemic has led to a dramatic increase in the number of survivors of critical illness. These survivors are at increased risk for physical, psychological, and cognitive impairments known collectively as post-intensive care syndrome (PICS). Little is known about the prevalence of PICS in COVID-19 survivors.

Objective: The objectives of this study were to develop and refine EMPOWER (Enhancing and Mobilizing the POtential for Wellness and Resilience), a brief manualized cognitive-behavioral, acceptance-based intervention for surrogate decision-makers of critically ill patients and to evaluate its preliminary feasibility, acceptability, and promise in improving surrogates' mental health and patient outcomes.

Method: Part 1 involved obtaining qualitative stakeholder feedback from 5 bereaved surrogates and 10 critical care and mental health clinicians. Stakeholders were provided with the manual and prompted for feedback on its content, format, and language.

Purpose Of Review: In under a year, coronavirus disease 2019 (COVID-19) has taken the lives of hundreds of thousands of Americans, leaving millions of survivors in its wake. The enormous number of people who survived acute illness but continue to have symptoms has highlighted the need for standardized evaluation of the post-COVID-19 patient. This review, based on the current literature and our experience, aims to guide the care of patients who have survived COVID-19.

Article Synopsis
  • New York City hospitals prepared for a surge of critically ill COVID-19 patients by developing comprehensive protocols across multiple areas, including infection control, staffing, and ICU capacity.
  • Strategies included enhancing bed capacity, using technology to reduce staff exposure, and ensuring effective communication and education to standardize care.
  • The collaborative efforts and detailed processes outlined during this urgent planning period could serve as a model for other healthcare facilities facing similar pandemic challenges in the future.

Background: The use of Do-Not-Resuscitate (DNR) orders has increased but many are placed late in the dying process. This study is to determine the association between the timing of DNR order placement in the intensive care unit (ICU) and nurses' perceptions of patients' distress and quality of death.

Methods: 200 ICU patients and the nurses (n = 83) who took care of them during their last week of life were enrolled from the medical ICU and cardiac care unit of New York Presbyterian Hospital/Weill Cornell Medicine in Manhattan and the surgical ICU at the Brigham and Women's Hospital in Boston.

Purpose Of Review: Diffuse alveolar hemorrhage (DAH) is a rare but devastating manifestation of antiphospholipid syndrome (APS) patients with or without other systemic autoimmune diseases. Data regarding diagnosis and treatment are limited to case series. We review diagnostic and therapeutic strategies employed in APS patients with DAH and discuss our experience in managing these complex patients.

Article Synopsis
  • Critical illness affects not only patients but also their informal caregivers, particularly those making critical decisions, leading to increased mental health risks.
  • The EMPOWER intervention is a new cognitive-behavioral approach aimed at supporting surrogate decision-makers in ICUs to enhance the quality of life for both patients and their caregivers.
  • The effectiveness of EMPOWER will be evaluated through a controlled trial, assessing its impact on mental health outcomes like stress and grief, as well as its acceptability and feasibility among participants.

Futile or potentially inappropriate care (futile/PIC) for dying inpatients leads to negative outcomes for patients and clinicians. In the setting of rising end-of-life health care costs and increasing physician burnout, it is important to understand the causes of futile/PIC, how it impacts on care and relates to burnout. Examine causes of futile/PIC, determine whether clinicians report compensatory or avoidant behaviors as a result of such care and assess whether these behaviors are associated with burnout.

Dyspnea is a common and distressing physical symptom among patients in the ICU and may be underdetected and undertreated. To determine the frequency of dyspnea relative to pain, the accuracy of nurses and personal caregiver dyspnea ratings relative to patient-reported dyspnea, and the relationship between nurse-detected dyspnea and treatment. This was an observational study of patients ( = 138) hospitalized in a medical ICU (MICU).

A 46-year-old previously healthy man presented with 1 week of headache, nausea, vomiting and dizziness. He was found to have cranial nerve deficits, his cerebrospinal fluid (CSF) demonstrated a lymphocytic pleocytosis and brain MRI suggested rhombencephalitis. Although Gram stains and cultures of his CSF did not identify a pathogen, DNA was detected by the FilmArray Meningitis/Encephalitis panel within 2 hours of performing a lumbar puncture.

Article Synopsis
  • Caring for patients at the end of life in the ICU can lead to emotional distress and burnout among nurses, but the specific factors contributing to this distress are not well understood.
  • A study involving 100 nurses revealed that factors such as patients' suffering, loss of dignity, and overall quality of death significantly influenced nurses' emotional distress.
  • Additionally, family dynamics, including fears about death and unrealistic expectations, were also identified as contributors to nurses' emotional challenges, suggesting that improving patient care and family support may benefit nurses' well-being.
