Background Intensive care units are high-acuity environments characterized by time pressure, medical complexity, and organizational demands. These conditions may influence clinicians’ ability to provide patient-centered care and contribute to forms of care perceived as fragmented or dehumanizing. Objective To examine how ICU clinicians describe and make sense of the pressures shaping everyday critical care practice, and how these pressures give rise to interacting patterns of care, including those described as hurry, blur, burden, and cruelty. Methods We conducted a qualitative study using focus groups with ICU clinicians from a large academic health system. Discussions were informed by the concept of the pathologies of care as sensitizing concepts. Four focus groups were held with physicians, nurses, advanced practice nurses, and a social worker ( N = 14). Transcripts were analyzed using directed content analysis with both deductive and inductive coding. Results Clinicians described these patterns not as discrete phenomena but as interrelated, context-dependent processes shaped by shared operational pressures such as time constraints, workload, and information demands. These dynamics were often viewed as inherent to the structure and culture of ICU care and were described as co-occurring and compounding. Communication emerged as both a contributor to and a potential mechanism for mitigation, alongside system-level strategies such as reducing documentation burden and leveraging artificial intelligence to support care delivery. Conclusions Patterns reflected in hurry, blur, burden, and cruelty are best understood as emergent properties of complex care systems. Addressing these dynamics may require system-level approaches to improve communication, reduce workload pressures, and support more patient-centered, humanizing care.

Variability in novel inflammatory markers (HBP and SAA) post-surgery could indicate ongoing perioperative inflammation. This pilot cohort study collected blood from 99 patients undergoing elective cardiac surgery at baseline, 24 hours, 7 days, and 3 months post-surgery. Inflammatory markers (HBP, SAA, PCT, CRP, IL-6) were measured with a point-of-care device. Demographic and clinical data were extracted from health records. Serum SAA increased significantly in the acute postoperative phase (M e [IQR];SAA baseline =81.1[87] vs SAA 24hr= 232.65[88.02];U[72]=2343,p<0.0001), remained elevated at 7 days (Me 7d =252.6[88.56];U[57]=1484,p<0.0001) and were still more pronounced than baseline at t 3m (Me 3m =118.44[101.52];U[38]=448,p=0.0008). HBP showed a significant rise at seven days (HBP baseline =45[26;89] vs HBP 7d =121[69.75;224.5]; U[56]=805,p<0.0001) then returned to near baseline by t 3m (Me 3m =32.5[15.75;98.5]). Traditional inflammatory markers PCT, CRP, and IL-6 demonstrated a rapid increase at t 24h and plateaued at t 7d . None of the biomarkers showed variability at baseline or postoperatively with preoperative status or postoperative complications. Cluster analysis of the inflammatory markers at 24 hours (t 24h ) identified distinct subgroups. Cluster #1-patients with a modest increase in all markers; Cluster#2 characterized with a robust increase in IL-6; Cluster #3 showed increase in CRP and decline in HBP; Cluster #4 showed a modest increase in IL-6 and decline in HBP; Cluster #5 represented a decline in both CRP and SAA. Patients in these clusters differ with respect to age, pre-existing peripheral artery disease, and borderline differences in perioperative acetaminophen use. SAA and HBP remain elevated longer than IL-6, CRP, and PCT after surgery, suggesting that inflammation may persist beyond 3 months.

Background/Objectives: Interstitial lung disease (ILD) occurs commonly in systemic sclerosis (SSc) and is the leading cause of mortality. There are limited data on the accuracy of lung auscultation in identifying the presence of ILD in patients with SSc. Methods: We retrospectively identified patients with newly diagnosed SSc who had documented lung auscultation findings and chest high-resolution computed tomography (HRCT) available for review. Diagnoses were made by rheumatologists at Mayo Clinic, Rochester, Minnesota, USA over a 4-year period. Pulmonary function measurements included lung volumes, spirometry, and single-breath diffusing capacity. Results: Among 151 patients with SSc (median age, 62 years), 72.2% were female and 55.0% were never smokers. Limited cutaneous SSc was the most common phenotype (67.3%). Seventy (46.4%) patients were evaluated by pulmonologists. There was evidence of ILD by HRCT in 69 patients (45.7%); the most common pattern of ILD was fibrotic nonspecific interstitial pneumonia (59.2%). Respiratory symptoms were present in 46.4% of those with ILD compared to 15.9% among those without. The sensitivity and specificity for crackles heard by rheumatologists in detecting ILD were 50.7% and 97.6%, respectively; for pulmonologists, 71.4% and 85.7%, respectively. Presence of crackles was associated with high positive predictive values (94.6% for rheumatologists vs. 92.1% for pulmonologists, respectively); negative predictive values were moderate (70.2% vs. 56.3%, respectively). Crackles correlated with lower pulmonary function measures but did not differ across ILD patterns. Conclusions: Detection of crackles on lung auscultation appears to be a specific and moderately sensitive indicator of ILD (often asymptomatic) in patients with newly diagnosed SSc. The presence of crackles correlates with worse pulmonary function but may be absent in early ILD.

A growing number of data-driven clinical decision support (CDS) tools are incorporated into tele-critical care, but the clinician perceptions of their utility are largely unknown. The objective of this web-based survey study was to understand the perceived utility of data-driven CDS in tele-critical care. The survey had 158 respondents (1.1% response rate), with 51.3% stating they currently use a data-driven CDS tool. Of those who responded about the impact of data-driven CDS, most (62.0%) reported a meaningful impact on workup, evidence-based care, or patient outcomes. Survey participants found CDS most useful if they or their colleagues had positive experiences with it, especially if it was responsible for improved patient outcomes. Thus, data-driven CDS is perceived useful for tele-critical care services.

Abstract Introduction: Maintenance of donor lung pressure is recommended to maintain inflation pressures of 12-15 mm Hg. This is particularly important given graft transportation in aircraft, due to the inevitable pressure changes. Case: We describe a case of a donor lung preservation system which maintained proper airway pressure during sudden cabin pressure loss requiring emergent landing. Discussion: The donor lungs were implanted without complication. Post-transplant course was notable for primary graft dysfunction (PGD) grade 1 at 24 hours, grade 2 at 48 hours, and grade 1 at 72 hours. At 3 months post-transplant, the patient has had no respiratory complications and has been noted to be doing well.

BACKGROUND: Mortality due to ischemic heart disease (IHD) has declined in countries with high socioeconomic development. Whether these declines extend to other settings, and whether socioeconomic development influences IHD mortality among men and women differently, is unknown. METHODS: We obtained annual data on sex-specific IHD mortality rates for countries/territories in the GBD study (Global Burden of Disease) from 1980 to 2021. The sociodemographic index (SI), a measure of socioeconomic development, was retrieved for each country/territory. Age-adjusted IHD mortality rates were modeled as a smooth function of sex, year, and SI. RESULTS: From 1980 to 2021, IHD mortality rates did not decrease in low SI settings for men or women. In contrast, mortality rates relative to 1980 declined by >25% in average SI settings (age-adjusted mortality per 100 000, 153–107 for women and 218–161 for men) and >50% in high SI settings (age-adjusted mortality per 100 000, 162–69 for women and 258–114 for men). Comparing the 20th versus 80th percentile of SI in 2021 (corresponding to lower versus higher socioeconomic development), mortality rates were 81% higher for men and 111% higher for women living in socioeconomically deprived settings ( P for difference by sex: 0.01), although absolute differences were larger in men. The association of low SI with higher IHD mortality was especially pronounced for mortality attributable to environmental/occupational risk factors (eg, particulate matter air pollution, lead exposure, and extremes of temperature), with mortality rates being 174% higher among women and 199% higher among men. CONCLUSIONS: Across the past 4 decades, low socioeconomic development was associated with no improvement in IHD mortality rates for men or women, in contrast to the large reductions observed in settings with high socioeconomic development. In contemporary settings, socioeconomic deprivation is associated with larger relative excess mortality in women and larger absolute excess mortality in men.

Cardiac tumors, though rare, present significant diagnostic and therapeutic challenges due to their heterogeneous nature and anatomical complexity. This narrative review synthesizes current evidence on prevalence, diagnostic modalities, and management strategies for primary and metastatic cardiac tumors. Echocardiography, cardiac MRI, and CT remain cornerstone imaging tools for differentiating tumors from non-neoplastic masses, while advances in PET/CT and tissue characterization techniques refine staging and treatment planning. Surgical resection with clear margins (R0) is critical for resectable tumors, particularly benign myxomas, though malignant tumors like sarcomas require multimodal approaches combining surgery, radiotherapy, and systemic therapies. Emerging strategies such as heart autotransplantation and staged resections offer promise for complex cases, while oligometastatic disease management highlights the role of stereotactic radiotherapy and immunotherapy. Key challenges include standardizing resection margins, optimizing neoadjuvant therapies, and addressing high recurrence rates in malignancies. Future directions emphasize integrating AI-driven imaging analysis, molecular biomarkers, and genomic profiling to personalize therapies, alongside global registries to enhance data on rare tumors. Equitable access to advanced diagnostics and multidisciplinary collaboration are essential to improve outcomes. This review underscores the need for standardized guidelines, technological innovation, and patient-centered research to address gaps in cardiac oncology.

The immune system’s response to an invading pathogen is the critical determinant in recovery from illness. Here, we hypothesize that the immune response will swiftly follow classical activation and a resolution trajectory in patients with the rapid evolution of symptoms if challenged by a viral pathogen for the first time. Alternatively, a dysregulated response will be signified by a protracted clinical trajectory. Consequently, we enrolled 106 patients during the first wave of COVID-19 and collected their blood within 24 h, 48 h, 7 days, and over 28 days from symptoms onset. The pathogenic burden was measured via serum levels of the S-spike protein and specific immunoglobulin titers against the S and N proteins of SARS-CoV-2. The nonspecific immunological response was gauged using interleukin 6, leukocytosis, and C-reactive protein. Coagulation status was assessed. Several serum biomarkers were used as surrogates of clinical outcomes. We identified four clusters depending on the onset of symptoms (immediate [A], 6 days [B], 12 days [C], and over 21 days [D]). High variability in the S-spike protein in cluster A was present. The corresponding immunoglobulin titer was random. Only procalcitonin differentiated clusters in terms of markers of nonspecific inflammation. Coagulation markers were not significantly different between clusters. Serum surrogates on cardiomyopathy and neuronal pathology exhibited significant variability. Implementation of ECMO or noninvasive ventilation was more prominent in cluster C and D. Interestingly, SOFA or APACHE II scores were not different between nominal (A and B) versus dysregulated clusters (C and D).

Objectives: The purpose of this study is to assess the efficacy, short- and long-term cardiovascular and non-cardiovascular mortalities and postoperative morbidities of surgical pulmonary embolectomy (SPE) for patients with massive or submassive pulmonary embolism. Methods: A comprehensive literature review was performed to identify articles reporting SPE for pulmonary embolism. The outcomes included in-hospital and long-term mortality in addition to postoperative morbidities. The random effect inverse variance method was used. Cumulative meta-analysis, leave-one-out sensitivity analysis, subgroup analysis and meta-regression were performed. Results: Among the 1949 searched studies in our systematic literature search, 78 studies met our inclusion criteria, including 6859 cases. The mean age ranged from 42 to 65 years. The percentage of males ranged from 25.6% to 86.7%. The median rate of preoperative cardiac arrest was 27.6%. The percentage of contraindications to preoperative systemic thrombolysis was 30.4%. The preoperative systemic thrombolysis use was 11.5%. The in-hospital mortality was estimated to be 21.96% (95% CI: 19.21–24.98); in-hospital mortality from direct cardiovascular causes was estimated to be 16.05% (95% CI: 12.95–19.73). With a weighted median follow-up of 3.05 years, the late cardiovascular and non-cardiovascular mortality incidence rates were 0.39 and 0.90 per person-year, respectively. The incidence of pulmonary bleeding, gastrointestinal bleeding, surgical site bleeding, non-surgical site bleeding and wound complications was 0.62%, 4.70%, 4.84%, 5.80% and 7.2%, respectively. Cumulative meta-analysis showed a decline in hospital mortality for SPE from 42.86% in 1965 to 20.56% in 2024. Meta-regression revealed that the publication year and male sex were associated with lower in-hospital mortality, while preoperative cardiac arrest, the need for inotropes or vasopressors and preoperative mechanical ventilation were associated with higher in-hospital mortality. Conclusions: This study demonstrates acceptable perioperative mortality rates and late cardiovascular and non-cardiovascular mortality in patients who undergo SPE for massive or submassive pulmonary embolism.
