Article Synopsis
  • Lower airway dysbiosis, characterized by an increase in specific bacteria, is linked to various severity grades of primary graft dysfunction (PGD) after lung transplantation, particularly in moderate and severe cases.
  • A study involving lower airway samples from 96 lung transplant recipients showed correlations between PGD severity and elevated levels of inflammatory markers, particularly neutrophils and specific cytokines, indicating a distinct inflammatory response.
  • Results suggest that microbial differences may influence host immune signaling, potentially exacerbating inflammation and contributing to PGD pathogenesis, highlighting the importance of microbial balance in lung health post-transplant.

Automated insulin delivery (AID) is widely available to people with type 1 diabetes (T1D), providing superior glycemic control versus traditional methods. The next generation of AID devices focus on minimizing user/device interactions, especially around meals ("full closed loop," [FCL]). Our goal was to assess the postprandial glycemic impact of the bolus priming system (BPS), an algorithm delivering fixed insulin doses based on the likelihood of a meal having occurred, in conjunction with UVA's latest AID.

Patients undergoing cardiac surgery experience significant physiologic derangements that place them at risk for multiple shock phenotypes. Any combination of cardiogenic, obstructive, hemorrhagic, or vasoplegic shock occurs commonly in post-cardiotomy patients. The approach to the diagnosis and management of these shock states has many facets that are distinct compared to non-surgical cardiac intensive care unit patients.

Research investigating ankle function during walking in a controlled ankle motion (CAM) boot has either placed markers on the outside of the boot or made major alterations to the structure of the CAM boot to uncover key landmarks. The aim of this study was to quantify joint kinematics and kinetics using "in-boot" skin markers whilst making only minimal structural alterations. Seventeen healthy participants walked at their preferred walking speed in two conditions: (1) in standard athletic trainers (ASICS patriot 8, ASICS Oceania Pty Ltd, USA), and (2) using a hard-cased CAM boot (Rebound® Air Walker, Össur, Iceland) fitted on the right foot.

Recent advances in therapy and the promulgation of multidisciplinary pulmonary embolism teams show great promise to improve management and outcomes of acute pulmonary embolism (PE). However, the absence of randomized evidence and lack of consensus leads to tremendous variations in treatment and compromises the wide implementation of new innovations. Moreover, the changing landscape of health care, where quality, cost, and accountability are increasingly relevant, dictates that a broad spectrum of outcomes of care must be routinely monitored to fully capture the impact of modern PE treatment.

Article Synopsis
  • - The study investigated the outcomes of patients with acute myocardial infarction (AMI) who required invasive mechanical ventilation, comparing those in medical ICUs (MICU) versus cardiac ICUs (CICU) from October 2015 to December 2019.
  • - Among the 12,639 patients studied, those in the CICU had a higher prevalence of serious conditions, but overall ventilator days were similar between both ICUs and in-hospital mortality rates were not significantly different until statistical adjustments were made.
  • - The results indicated that admission to the CICU was linked to lower in-hospital mortality rates for AMI patients, suggesting that better triage to specialized cardiac care could improve outcomes.

  • The study investigates how different types of mechanical loading (intermittent vs. continuous) affect bone formation in mouse pre-osteoblast cells (MC3T3) over various time periods (1, 3, and 12 days).
  • Results showed that intermittent loading significantly increased alkaline phosphatase (ALP) activity, a marker of bone formation, compared to continuous and unloaded conditions.
  • While intermittent loading led to higher ALP levels, it resulted in lower concentrations of procollagen 1 N-terminal propeptide (PINP) at day 3, showing a complex relationship between loading type and bone formation markers.

Introduction: Mounting evidence indicates that an individual's humoral adaptive immune response plays a critical role in the setting of SARS-CoV-2 infection, and that the efficiency of the response correlates with disease severity. The relationship between the adaptive immune dynamics in the lower airways with those in the systemic circulation, and how these relate to an individual's clinical response to SARS-CoV-2 infection, are less understood and are the focus of this study.

Material And Methods: We investigated the adaptive immune response to SARS-CoV-2 in paired samples from the lower airways and blood from 27 critically ill patients during the first wave of the pandemic (median time from symptom onset to intubation 11 days).
