There is increasing interest in the use of home-based monitoring in people with chronic lung diseases to improve access to care, support patient self-management, and facilitate the collection of information for clinical care and research. However, integration of home-based monitoring into clinical and research settings requires careful consideration of test performance and other attributes. There is no published guidance from professional respiratory societies to advance the science of home-based monitoring for chronic lung disease.

Article Synopsis
  • Persistent acute kidney injury (pAKI) has a worse prognosis than transient acute kidney injury (AKI) in critically ill patients, but its impact and definitions are less understood in organ transplant recipients.
  • A systematic review of 25 studies involving 6,330 patients showed a wide variation in the incidence and definitions of pAKI among heart, lung, and liver transplant recipients.
  • pAKI is linked to higher rates of new chronic kidney disease, graft dysfunction, and long-term mortality, highlighting the need for standardized definitions in future research.

Article Synopsis
  • - Lung cancer is a major global health issue, and low-dose computed tomography (LDCT) screening can reduce mortality rates by up to 25%, making it a cost-effective solution that European countries are encouraged to explore for implementation.
  • - A task force reviewed literature and engaged in discussions to develop recommendations for launching lung cancer screening programs in Portugal, focusing on the guidelines of the World Health Organization tailored to the local healthcare system.
  • - Key areas covered in the recommendations include identifying eligible populations, invitation methods, radiological requirements, result reporting, referral processes, and the integration of smoking cessation programs as essential for effective lung cancer screening.

Introduction: Acute kidney injury (AKI) is a common complication of sepsis associated with increased risk of death. Preclinical data and observational human studies suggest that activation of AMP-activated protein kinase, an ubiquitous master regulator of energy that can limit mitochondrial injury, with metformin may protect against sepsis-associated AKI (SA-AKI) and mortality. The Randomized Clinical Trial of the Safety and FeasibiLity of Metformin as a Treatment for sepsis-associated AKI (LiMiT AKI) aims to evaluate the safety and feasibility of enteral metformin in patients with sepsis at risk of developing SA-AKI.

Although the value of patient and public involvement and engagement (PPIE) activities in the development of new interventions and tools is well known, little guidance exists on how to perform these activities in a meaningful way. This is particularly true within large research consortia that target multiple objectives, include multiple patient groups, and work across many countries. Without clear guidance, there is a risk that PPIE may not capture patient opinions and needs correctly, thereby reducing the usefulness and effectiveness of new tools.

Introduction: There is high heterogeneity of outcomes and measures reported in pulmonary rehabilitation (PR) trials of people with chronic obstructive pulmonary disease (COPD). This hinders study comparability and benchmarking of PR. We have developed a core outcome set (COS) to overcome these challenges.

This work provides a screening of organic contaminants and characterization of the dissolved organic matter in the sewer network until the municipal wastewater treatment plant (WWTP), identifying the network areas with a higher degree of contamination and their impact on the WWTP performance, particularly in the activated sludge reactor. Three monitoring campaigns were carried out at six selected locations of the sewage system (PVZ-1, PVZ-2, PS-F, PS-VC, CP-VC, and PS-T), influent (WWTP) and effluent (WWTP) of the WWTP. Advanced analytical techniques were employed, namely excitation/emission matrix fluorescence-parallel factor analysis (EEM-PARAFAC), size exclusion chromatography with organic carbon detector (SEC-OCD), and liquid chromatography with high-resolution-mass spectrometric detection (LC-HRMS).

Background: Pegylated liposomal doxorubicin (PLD) is among the most active therapies for recurrent/progressive ovarian cancer (OC). Low-density lipoprotein receptor-related protein 1B (LRP1B) is one of the 10 most significantly deleted genes in human cancers. It mediates endocytosis of several factors from the cellular environment including liposomes.

Clinical trials evaluating the management of acute exacerbations of COPD assess heterogeneous outcomes, often omitting those that are clinically relevant or more important to patients. We have developed a core outcome set, a consensus-based minimum set of important outcomes that we recommend are evaluated in all future clinical trials on exacerbations management, to improve their quality and comparability. COPD exacerbations outcomes were identified through methodological systematic reviews and qualitative interviews with 86 patients from 11 countries globally.

To investigate the association between cardiovascular risk and biomarkers in patients with Type 2 diabetes (T2DM). Cross-sectional study, with evaluation of traditional and new biomarkers (serum FGF-23, Syndecan-1 [Sdc-1] and vascular cell adhesion molecule-1 [VCAM-1] and urinary VEGF and kidney injury molecule-1 [KIM-1]) and risk scores (Framingham-FRS and UK Prospective Diabetes Study [UKPDS]). 128 diabetics were included, with predominance of high risk by FRS and low risk by UKPDS.

Fluoride concentrations in groundwater can be high in some Brazilian aquifers and therefore these waters should be treated before consumption. This study assessed the properties of Mn-oxide-coated alumina (AM) prepared by two-step heating in water defluoridation. The release of secondary contaminants (e.

Background And Aims: Deep venous thrombosis (DVT) is known to occur preferentially on the left lower extremity. The renowned surgeon Denis Burkitt advanced the theory that a heavy sigmoid colon would compress the left pelvic veins and predispose to DVT. Our study aimed to evaluate this hypothesis by comparing the laterality distributions with and without a prior colectomy.

Randomised controlled trials (RCTs) on the management of COPD exacerbations evaluate heterogeneous outcomes, often omitting those that are clinically important and patient relevant. This limits their usability and comparability. A core outcome set (COS) is a consensus-based minimum set of clinically important outcomes that should be evaluated in all RCTs in specific areas of health care.

Background: Incident acute kidney injury (AKI) in critically ill patients with acute on chronic liver failure (ACLF) is associated with poor prognosis. The role of continuous renal replacement therapy (CRRT) is not well established for patients with ACLF and AKI.

Materials And Methods: We conducted a retrospective cohort study to examine clinical outcomes in 66 patients with ACLF and AKI requiring CRRT.

As the average age of the population increases, so will the prevalence of chronic respiratory diseases and associated multimorbidity. This will result in a more complex clinical environment. Part of the solution will be to allow patients to be co-creators in the design of their care.

Unlabelled: There are currently 3.5 million people in Europe who require medical oxygen, and as life expectancies increase, this figure is likely to grow. At the same time, air travel is becoming more accessible to a wider range of people, as costs of flights fall, and airlines and airports make improvements to the accessibility of their services.
