Lung transplant, intensive care

OBJECTIVE: To evaluate the clinical and imaging characteristics of SARS-CoV-2 breakthrough infection in hospitalized immunocompromised patients in comparison with immunocompetent patients. MATERIALS AND METHODS: This retrospective study analyzed consecutive adult patients hospitalized for COVID-19 who received at least one dose of the SARS-CoV-2 vaccine at two academic medical centers between June 2021 and December 2022. Immunocompromised patients (with active solid organ cancer, active hematologic cancer, active immune-mediated inflammatory disease, status post solid organ transplantation, or acquired immune deficiency syndrome) were compared with immunocompetent patients...

BACKGROUND:  In older patients, a limited physical reserve is considered a contraindication for lung transplantation (LTx). Herein, we aimed to establish a computed tomography (CT)-based quantification of physical reserve in older patients scheduled for transplantation. METHODS:  This retrospective study included patients older than 60 years who received LTx. Semiautomatic measurements of the mediastinal fat area and the dorsal muscle group area in pretransplantation CT scans were performed, and normalized data were correlated with clinical parameters...

BACKGROUND: Sinusoidal obstruction syndrome is a potentially fatal complication following hematopoietic cell transplantation, high-intensity chemotherapies and increasingly seen with calicheamicin based leukemia therapies. Paediatric specific European Society for Blood and Marrow Transplantation (pEBMT) diagnostic criteria have demonstrated benefit in single center studies compared to historic criteria. Yet, the extent to which they have been universally implemented remains unclear. METHODS: We conducted a retrospective multi-centre study to examine the potential impact of the Baltimore, modified Seattle and pEBMT criteria on the incidence, severity, and outcomes of sinusoidal obstruction syndrome among paediatric hematopoietic cell transplantation patients...

BACKGROUND: Approximately one in three survivors of critical illness suffers from intensive-care-unit-acquired weakness, which increases mortality and impairs quality of life. By counteracting immobilization, a known risk factor, active mobilization may mitigate its negative effects on patients. In this single-center trial, the effect of robotic-assisted early mobilization in the intensive care unit (ICU) on patients' outcomes was investigated. METHODS: We enrolled 16 adults scheduled for lung transplantation to receive 20 min of robotic-assisted mobilization and verticalization twice daily during their first week in the ICU (intervention group: IG)...

BACKGROUND AND OBJECTIVE: High variability in tacrolimus pharmacokinetics directly after lung transplantation (LuTx) may increase the risk for acute kidney injury (AKI) and transplant rejection. The primary objective was to compare pharmacokinetic variability in patients receiving tacrolimus orally versus intravenously early after LuTx. METHODS: Pharmacokinetic and clinical data from 522 LuTx patients transplanted between 2010 and 2020 in two university hospitals were collected to compare orally administered tacrolimus to intravenous tacrolimus early post-transplantation...

BACKGROUND: Prior studies have assessed the impact of the pretransplantation recipient body mass index (BMI) on patient outcomes after lung transplantation (LT), but they have not specifically addressed early postoperative complications. Moreover, the impact of donor BMI on these complications has not been evaluated. The first aim of this study was to assess complications during hospitalization in the ICU after LT according to donor and recipient pretransplantation BMI. METHODS: All the recipients who underwent LT at Bichat Claude Bernard Hospital, Paris, between January 2016 and August 2022 were included in this observational retrospective monocentric study...

BACKGROUND AND AIM: SARS-CoV-2 infection has been linked to hyperinflammation in multiple organs with a potential mechanistic link with resulting autoimmunity. There have been reports of many inflammatory complications following COVID-19, including sarcoidosis. A literature review on new-onset sarcoidosis following COVID-19 is lacking. We evaluated potential associations between COVID-19 and development of new-onset sarcoidosis. METHODS: Articles discussing biopsy-proven sarcoidosis after confirmed COVID-19 infection, published 1956 until April 2023, were included...

The post-operative intensive care experience of a school-aged child who received living-donor bilateral lobar lung transplantation due to acute respiratory distress syndrome and interstitial pulmonary fibrosis is discussed in this paper. The patient received lungs donated by her parents in a "living-donor bilateral lobar lung transplantation" due to severe lung function impairment. The patient felt anxious due to her long-term hospitalization for preoperative evaluation, various invasive treatments, and postoperative rehabilitation...

Hemodynamic derangements are defining features of cardiogenic shock. Randomized clinical trials have examined the efficacy of various therapeutic interventions, from percutaneous coronary intervention to inotropes and mechanical circulatory support (MCS). However, hemodynamic management in cardiogenic shock has not been well-studied. This State-of-the-Art review will provide a framework for hemodynamic management in cardiogenic shock, including a description of the four therapeutic phases from initial 'Rescue' to 'Optimization', 'Stabilization' and 'de-Escalation or Exit therapy' (R-O-S-E), phenotyping and phenotype-guided tailoring of pharmacological and MCS support, to achieve hemodynamic and therapeutic goals...

Owing to the extremely short supply of donor lungs in Japan, a unique medical consultant (MC) system was initiated in 2002 to increase the organ availability through intensive management of donors. First, heart transplant surgeons were sent to procurement hospitals as MCs to assess donor organ function and provide intensive care to donors. MCs requested that donor attending doctors perform frequent phlegm aspiration with a bronchoscope, leading to a higher lung availability and better outcomes after lung transplantation...

BACKGROUND: Human Metapneumovirus (HMPV) belongs to the Pneumoviridae family and is responsible for respiratory infections. Mild infections are well-recognized in children, while its precise impact in various categories of immunocompromised adults has not been well addressed. RESEARCH QUESTION: We retrospectively studied HMPV infections in immunocompromised adults followed in two large French university medical centers. STUDY DESIGN AND METHODS: We identified immunocompromised adults with positive HMPV Polymerase Chain Reaction (PCR) for 36 months and reviewed their medical charts...

BACKGROUND: Infections are one of the most common causes of death after lung transplant (LT). However, the benefit of 'targeted' prophylaxis in LT recipients pre-colonized by Gram-negative (GN) bacteria is still unclear. METHODS: All consecutive bilateral LT recipients admitted to the Intensive Care Unit of the University Hospital of Padua (February 2016-2023) were retrospectively screened. Only patients with pre-existing GN bacterial isolations were enrolled and analyzed according to the antimicrobial surgical prophylaxis ('standard' vs...

OBJECTIVES: To describe the epidemiology, surgical complications, and long-term outcomes after tracheostomy in pediatric oncology and/or hematopoietic stem cell transplantation (HSCT) patients in U.S. Children's Hospitals. DESIGN: Retrospective cohort from the Pediatric Health information System (PHIS) database, 2009-2020. SETTING: The PHIS dataset incorporates data from 48 pediatric hospitals in the Children's Hospital Association. PATIENTS: Patients 0-21 years old with an oncologic diagnosis and/or underwent HSCT, received a tracheostomy, and were discharged from hospital between January 1, 2009, and December 31, 2020...

Objective: To summarize and analyze the clinical features, treatment, and prognosis of pulmonary artery stenosis post-lung transplantation. Methods: A 62-year-old male patient was admitted to the hospital with a cough and chest tightness of over a year's duration, which had worsened in the last two months, leading to the diagnosis of idiopathic pulmonary fibrosis. The clinical data were observed and reviewed post-left allograft single lung transplantation. Literature searches were conducted using the keywords "lung transplantation" "stenosis, pulmonary artery" and "postoperative complications" in CNKI, Wanfang Medical Network, and PubMed databases up to December 2022...

BACKGROUND: Pulmonary rehabilitation is recognized widely as one of the most effective measures to promote postoperative recovery of lung transplant recipients (LTRs), and it has positive effects on both short- and long-term quality of life (QoL) and survival outcomes. However, no standardized pulmonary rehabilitation training programs exist specifically for LTRs. The pulmonary rehabilitation programs widely used in clinical practice focus mainly on exercise or respiratory training, to some extent neglecting other therapeutic methods that could promote patient health, such as nutrition support, pain control, spiritual comfort, and so on...

Chronic eosinophilic pneumonia (CEP) is a rare, idiopathic interstitial lung disease characterised by the accumulation of eosinophils in the pulmonary interstitia and alveoli. Patients with CEP respond well to systemic corticosteroid therapy and infrequently progress to end-stage lung disease. We report a case of a woman in her 40s with previously stable, steroid-responsive CEP who experienced a critical deterioration of her CEP at 25 weeks of gestation during her third pregnancy. The patient was admitted to the intensive care unit due to respiratory failure requiring intubation and mechanical ventilation...

Background: Drug-drug interactions (DDIs) are a major but preventable cause of adverse drug reactions. There is insufficient information regarding DDIs in lung transplant recipients. Objective: This study aimed to determine the prevalence of potential DDIs (pDDIs) in intensive care unit (ICU) lung transplant recipients, identify the real DDIs and the most frequently implicated medications in this vulnerable population, and determine the risk factors associated with pDDIs. Methods: This retrospective cross-sectional study included lung transplant recipients from January 2018 to December 2021...

BACKGROUND: Temporary mechanical circulatory support as well as multidisciplinary team approach in a regional care organization might improve survival of cardiogenic shock. No study has evaluated the relative effect of each temporary mechanical circulatory support on mortality in the context of a regional network. METHODS: Prospective observational data were retrieved from patients consecutively admitted with cardiogenic shock to the intensive care units in 3 centres organized into a regional cardiac assistance network...

OBJECTIVE: The aim of this study was to determine physiotherapists' current practices and perspectives regarding their role in caring for people who are potential lung donors in the intensive care unit (ICU). METHODS: A qualitative descriptive design was used. Qualitative data were collected through audio-recorded, semistructured focus groups with a purposive sample of physiotherapists with experience working with people who are potential lung donors in ICUs. Two investigators completed independent thematic analysis to identify themes...

BACKGROUND: Blood transfusion in the perioperative cardiothoracic setting has accepted risks including deep sternal wound infection, increased intensive care unit length of stay, lung injury, and cost. It has an immunomodulatory effect which may cause allo-immunisation. This may influence long-term survival through immune-mediated factors. Targeting coagulation defects to reduce unnecessary or inappropriate transfusions may reduce these complications. METHODS: In 2012, an institution-wide patient blood management evidence-based algorithmic bleeding management protocol was implemented at The Prince Charles Hospital, Brisbane, Australia...
