IMPORTANCE: Older adults with recent injuries can have impaired long-term biopsychosocial function and may benefit from interventions adapted to their needs. OBJECTIVE: To determine if a collaborative care intervention, Trauma Medical Home (TMH), improved the biopsychosocial function of older patients in the year after injury. DESIGN, SETTING, AND PARTICIPANTS: This was a single-blinded, randomized clinical trial conducted at 4 level I trauma centers in Indianapolis, Indiana, and Madison, Wisconsin...

BACKGROUND: Therapeutic drug monitoring (TDM) of anti-infectives such as linezolid is routinely performed in blood of intensive care unit (ICU) patients to optimize target attainment. However, the concentration at the site of infection is considered more important for a successful therapy. Until now, bronchoalveolar lavage (BAL) is the gold standard to measure intrapulmonary concentrations of anti-infective agents. However, it is an invasive method and unsuitable for regular TDM. The aim of this proof-of-concept study was to investigate whether it is possible to reliably determine the intrapulmonary concentration of linezolid from endotracheal aspiration (ENTA)...

BACKGROUND: Assessment of dynamic parameters to guide fluid administration is one of the mainstays of current resuscitation strategies. Each test has its own limitations, but passive leg raising (PLR) has emerged as one of the most versatile preload responsiveness tests. However, it requires real-time cardiac output (CO) measurement either through advanced monitoring devices, which are not routinely available, or echocardiography, which is not always feasible. Analysis of the hepatic vein Doppler waveform change, a simpler ultrasound-based assessment, during a dynamic test such as PLR could be useful in predicting preload responsiveness...

PURPOSE: Sarcopenia, defined as the loss of muscle mass and strength, can hinder postoperative recovery and raise mortality rates. However, the current evidence on the harmful effects of sarcopenia in older patients in orthopedic and trauma care is unclear. This scoping review investigates different definitions that were used for the diagnosis of sarcopenia in older patients in orthopedic and trauma care and what adverse consequences have been examined. METHODS: We performed a comprehensive literature search in PubMed and Embase, following the PRISMA guidelines...

RATIONALE: Changes in peripheral blood cell populations have been observed but not detailed at single-cell resolution in idiopathic pulmonary fibrosis (IPF). OBJECTIVES: To provide an atlas of the changes in the peripheral immune system in stable and progressive IPF. METHODS: Peripheral blood mononuclear cells (PBMCs) from IPF patients and controls were profiled using 10x Chromium 5' single-cell RNA sequencing (scRNA-seq). Flow cytometry was used for validation...

RATIONALE: Bronchiectasis is characterised by acute exacerbations but the biological mechanisms underlying these events is poorly characterised. Objectives To investigate the inflammatory and microbial characteristics of exacerbations of bronchiectasis. METHODS: 120 patients with bronchiectasis were enrolled and presented with acute exacerbations within 12 months. Spontaneous sputum samples were obtained during a period of clinical stability and again at exacerbation prior to receipt of antibiotic treatment...

OBJECTIVES: To compare levetiracetam and phenytoin as prophylaxis for the short-term development of status epilepticus (SE) during care of pediatric patients with acute severe traumatic brain injury (TBI). DESIGN: Nonprespecified secondary analysis using propensity score matching. SETTING: We used the Approaches and Decisions in Acute Pediatric TBI Trial (ADAPT NCT04077411) dataset (2014-2017). SUBJECTS: Patients less than 18 years old with Glasgow Coma Scale Score less than or equal to 8 who received levetiracetam or phenytoin as a prophylactic anticonvulsant therapy...

OBJECTIVE: To examine the physical function and respiratory muscle strength of patients - who recovered from critical COVID-19 - after intensive care unit discharge to the ward on Days one (D1) and seven (D7), and to investigate variables associated with functional impairment. METHODS: This was a prospective cohort study of adult patients with COVID-19 who needed invasive mechanical ventilation, non-invasive ventilation or high-flow nasal cannula and were discharged from the intensive care unit to the ward...

INTRODUCTION: fat embolism syndrome (FES) is an acute respiratory disorder that occurs when an inflammatory response causes the embolization of fat and marrow particles into the bloodstream. The exact incidence of FES is not well defined due to the difficulty of diagnosis. FES is mostly associated with isolated long bone trauma, and it is usually misdiagnosed in other trauma cases. The scope of this study was to identify and search the current literature for cases of FES in nonorthopedic trauma patients with the aim of defining the etiology, incidence, and main clinical manifestations...

Clostridium botulinum produces the most potent bacterial toxin, botulinum toxin A (BTXA), which has various therapeutic and cosmetic indications. Intragastric BTXA injection is a new obesity treatment method that was argued to be safe due to the inactivation of BTXA through the liver or metabolization within the gastric wall. However, a 36-year-old woman was admitted to the intensive care unit (ICU) due to developing botulism as a result of an intragastric injection of BTXA. The diplopia, headaches, ptosis, decreased muscle force, and respiratory distress two days after injection were her first chief complaints, and also, she experienced significant dysphagia, hoarse voice, thick tongue, constipation, hyposmia, and hypogeusia after two weeks...

BACKGROUND: A noninvasive and accurate method of identifying fluid responsiveness in hemodynamically unstable patients has long been sought by physicians. Carotid ultrasound (US) is one such modality previously canvassed for this purpose. The aim of this novel systematic review and meta-analysis is to investigate whether critically unwell patients who are requiring intravenous (IV) fluid resuscitation (fluid responders) can be identified accurately with carotid US. METHODS: The protocol was registered with PROSPERO on the 30/11/2022 (ID number: CRD42022380284)...

AIM: Reducing the blood transfusion volume is important in severe trauma. We hypothesized that carbazochrome sodium sulfonate (CSS) combined with tranexamic acid (TXA) would reduce blood transfusions in severe trauma. METHODS: From April 2017 to March 2023, data were collected from patients (aged ≥16 years) admitted to our hospital for trauma and administered packed red blood cells (pRBC) and plasma transfusions within 12 h postinjury. Patients infused with CSS and TXA (CSS + TXA group) were compared with those infused with TXA alone (TXA group)...

BACKGROUND: A microbiological cause of infection is infrequently identified in critically unwell children with a respiratory infection. Molecular diagnostic arrays provide an alternative. These tests are becoming more broadly available, but little is known about how clinicians interpret the results to impact clinical decision making. CASE DESCRIPTION: Here we describe three cases of bacterial and fungal lower respiratory tract infection (LRTI) diagnosed in the paediatric intensive care unit (PICU) using a custom 52 respiratory pathogen TaqMan array card (TAC)...

People with human immunodeficiency virus (HIV) have a 50% excess risk for intensive care unit (ICU) admission, often for non-HIV-related conditions. Despite this, clear guidance for managing antiretroviral therapy (ART) in this setting is lacking. Selecting appropriate ART in the ICU is complex due to drug interactions, absorption issues, and dosing adjustments. Continuing ART in the ICU can be challenging due to organ dysfunction, drug interactions, and formulary limitations. However, with careful consideration, continuation is often feasible through dose adjustments or alternative administration methods...

The evolution of critical care medicine is inextricably linked to the development of critical care procedures. These procedures not only facilitate diagnosis and treatment of critically ill patients, but also provide valuable insights into disease pathophysiology. While critical care interventions offer undeniable benefits, the potential for iatrogenic complications necessitates careful consideration. The recent surge in critical care ultrasound (US) utilization is a testament to its unique advantages: non-invasiveness, real-time bedside availability, direct visualization of internal structures, elimination of ionizing radiation exposure, repeatability, and relative ease of learning...

OBJECTIVE: Patients with acute myocardial infarction (AMI) complicated by respiratory failure require antiplatelet regimens which often cannot be stopped and may increase bleeding from tracheostomy. However, there is limited available data on both the proportion of patients undergoing tracheostomy and the impact on antiplatelet regimens on outcomes. METHODS: Utilizing the Vizient® Clinical Data Base, we identified patients ≥18 years admitted from 2015 to 2019 with a primary diagnosis of AMI and requiring invasive mechanical ventilation (IMV)...
