Patients' and Caregivers' Perceptions of Intensive Care Unit Hospitalization and Recovery

BACKGROUND

Telehealth-based intensive care unit recovery clinics (ICU-RCs) can increase access to post-ICU recovery care for patients and their families. It is crucial to understand patients' and caregivers' experience of illness and recovery to build patient- and family-centered ICU-RCs.

OBJECTIVE

To explore patients' and caregivers' perceptions of ICU hospitalization and recovery.

METHODS

Individual semistructured telephone interviews were conducted with 14 patients and 12 caregivers who participated in a telehealth ICU-RC. This study was guided by qualitative description methodology. Conventional content analysis was used to analyze the data.

RESULTS

Patients described their ICU hospitalization as scary, traumatic, and lonely. Participants' feedback on hospitalization ranged from praise to criticism. Patients wanted more realistic and detailed prognostication about post-ICU recovery and more physical therapy after discharge. Patients strongly valued the mental health component of ICU-RC visits, which contrasted with the scant attention paid to mental health in other postdischarge health care settings. Their knowledge about post-ICU recovery and connectedness to a primary care provider varied.

CONCLUSIONS

Examining patients' and caregivers' perceptions of ICU hospitalization and recovery highlights ICU-RC components that can be strengthened to support patient- and family-centered recovery. The ICU-RC staff should invite patients to share feedback about their ICU stay; give a timely, realistic prognosis for recovery; offer mental health consultations; provide physical therapy; and partner with patients and their caregivers to develop and deliver post-ICU care.

Ascorbic acid supports ex vivo generation of plasmacytoid dendritic cells from circulating hematopoietic stem cells

Plasmacytoid dendritic cells (pDCs) constitute a rare type of immune cell with multifaceted functions, but their potential use as a cell-based immunotherapy is challenged by the scarce cell numbers that can be extracted from blood. Here, we systematically investigate culture parameters for generating pDCs from hematopoietic stem and progenitor cells (HSPCs). Using optimized conditions combined with implementation of HSPC pre-expansion, we generate an average of 465 million HSPC-derived pDCs (HSPC-pDCs) starting from 100,000 cord blood-derived HSPCs. Furthermore, we demonstrate that such protocol allows HSPC-pDC generation from whole-blood HSPCs, and these cells display a pDC phenotype and function. Using GMP-compliant medium, we observe a remarkable loss of TLR7/9 responses, which is rescued by ascorbic acid supplementation. Ascorbic acid induces transcriptional signatures associated with pDC-specific innate immune pathways, suggesting an undescribed role of ascorbic acid for pDC functionality. This constitutes the first protocol for generating pDCs from whole blood and lays the foundation for investigating HSPC-pDCs for cell-based immunotherapy.

Sex-based differences in chronic total occlusion management and long-term clinical outcomes

BACKGROUND

Sex differences in coronary artery disease presentation and outcomes have been described. The aim of this study was to compare sex disparities in chronic total occlusion (CTO) management and long-term outcomes.

METHODS

All consecutive patients with at least one CTO diagnosed in our center between 2010 and 2014 were included. Demographic and clinical data were registered. All-cause and cardiac mortality were assessed during a median follow-up of 4.03 years (IQR 2.6-4.8).

RESULTS

A total of 1248 patients (67.3 ± 10.9 years; 16% female) were identified. Women were older, had a higher prevalence of type 2 DM and a lower ventricle ejection fraction compared to men (p < .05). Although women had major proportion of positive result for severe ischemia-viability test (86% vs. 74%; p = .01), they were more often treated with MT alone compared to male (57% vs 51%; p = .02). During follow-up, 386 patients (31%) died. Women presented a higher rate of all-cause and cardiac mortality, and hospitalizations for heart failure independently of treatment strategy, compared to men (p < .001). In multivariable analysis female sex was associated with higher cardiac mortality [HR 1.67, 95% CI 1.10-2.57; p < .001]. Among women, the independent predictors for all-cause and cardiac mortalities were age, MT of the CTO and ACEF (age, creatinin and ejection fraction) score.

CONCLUSIONS

A significant sex gap regarding CTO treatment was observed. Female sex was an independent predictor for cardiac mortality at long-term follow-up. More data are needed to support these findings.
