Hand Burn Injuries and Occupational Impairment: A Study on the Impact of Burn Injuries on Return-to-Work Outcomes from the Burn Model System research program.

Return to work (RTW) after burn injury is dependent on many variables, including type and location of burn injury, access to care, and pre-injury mental and physical health. Noting that prior studies were limited by small sample sizes, we aimed to use a large database to explore the associations between hand burn severity, functional hand outcomes, and RTW post-injury. Data from a multicenter longitudinal study were analyzed.

The Delay of Recanalisation of Acutely Thrombosed Dialysis Arteriovenous Access Until the Next Workday has No Negative Impact on Clinical Outcome.

Purpose: The necessity of providing endovascular recanalization of acutely thrombosed arteriovenous access (AV access) during weekend is questionable, since hemodialysis can alternatively be achieved by temporarily placed non-tunneled central venous catheters (CVC). Interventional therapy of acutely thrombosed AV access is provided only on weekdays in the study center. This study aimed to compare outcomes in patients admitted on weekdays and on the weekend.

Chemokine receptor CXCR4 based positron emission tomography imaging in systemic sclerosis-related interstitial lung disease.

Objective: To assess chemokine receptor CXCR4 expression in lung parenchyma and on peripheral immune cells in systemic sclerosis-related interstitial lung disease (SSc-ILD) patients.

Methods: SSc-ILD patients underwent 68Ga- CPCR4 Trifluoroacetate positron emission tomography (PET) scan, SUVmean in different lung regions and architecturally abnormal areas, and receiver operating characteristic (ROC) curves were analyzed. CXCR4 expression on peripheral immune cells using flow cytometer was studied and correlated with the different lung regions.

Sodium quantification in skeletal muscle: comparison between Cartesian gradient-echo and radial ultra-short echo time Na MRI techniques.

Background: Clinical magnetic resonance imaging (MRI) studies often use Cartesian gradient-echo (GRE) sequences with ~2-ms echo times (TEs) to monitor apparent total sodium concentration (aTSC). We compared Cartesian GRE and ultra-short echo time three-dimensional (3D) radial-readout sequences for measuring skeletal muscle aTSC.

Methods: We retrospectively evaluated 211 datasets from 112 volunteers aged 62.

Modification of Dialysate Na Concentration but not Ultrafiltration or Dialysis Treatment Time Affects Tissue Na Deposition in Patients on Hemodialysis.

Introduction: Tissue Na overload is present in patients receiving hemodialysis (HD) and is associated with cardiovascular mortality. Strategies to actively modify tissue Na amount in these patients by adjusting the HD regimen have not been evaluated.

Methods: In several substudies, including cross-sectional analyses ( = 75 patients on HD), a cohort study and a cross-over interventional study ( = 10 patients each), we assessed the impact of ultrafiltration (UF) volume, prolongation of dialysis treatment time, and modification of dialysate Na concentration on tissue Na content using Na magnetic resonance imaging (Na-MRI).

Fire sparks upslope range shifts of North Cascades plant species.

As ongoing climate change drives suitable habitats to higher elevations, species ranges are predicted to follow. However, observed range shifts have been surprisingly variable, with most species differing in rates of upward shift and others failing to shift at all. Disturbances such as fires could play an important role in accelerating range shifts by facilitating recruitment in newly suitable habitats (leading edges) and removing adults from areas no longer suited for regeneration (trailing edges).

Myocardial Oedema as a Consequence of Viral Infection and Persistence-A Narrative Review with Focus on COVID-19 and Post COVID Sequelae.

Microvascular integrity is a critical factor in myocardial fluid homeostasis. The subtle equilibrium between capillary filtration and lymphatic fluid removal is disturbed during pathological processes leading to inflammation, but also in hypoxia or due to alterations in vascular perfusion and coagulability. The degradation of the glycocalyx as the main component of the endothelial filtration barrier as well as pericyte disintegration results in the accumulation of interstitial and intracellular water.

Antiretroviral Regimen and Pregnancy Outcomes of Women Living with HIV in a US Cohort.

Women who are pregnant and living with HIV have traditionally been excluded from clinical trials regarding new pharmacotherapy. Immediate initiation of antiretroviral therapy (ART) is recommended for women who are pregnant and living with HIV. Integrase inhibitors (INSTIs) are first-line recommended agents as they lead to more rapid HIV viral load reduction.

Perioperative Atezolizumab Plus Fluorouracil, Leucovorin, Oxaliplatin, and Docetaxel for Resectable Esophagogastric Cancer: Interim Results From the Randomized, Multicenter, Phase II/III DANTE/IKF-s633 Trial.

Purpose: This trial evaluates the addition of the PD-L1 antibody atezolizumab (ATZ) to standard-of-care fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) as a perioperative treatment for patients with resectable esophagogastric adenocarcinoma (EGA).

Methods: DANTE started as multicenter, randomized phase II trial, which was subsequently converted to a phase III trial. Here, we present the results of the phase II proportion, focusing on surgical pathology and safety outcomes on an exploratory basis.

Sex-specific aspects in patients with oropharyngeal squamous cell carcinoma: a bicentric cohort study.

Background: Oropharyngeal squamous cell carcinoma (OPSCC) is the only subgroup of head neck cancer that presents with an increased incidence. Gender-specific studies in other cancer entities have revealed differences in treatment response and prognosis. However, only limited data in OPSCC according to gender and human papillomavirus (HPV) status exist.

Material And Methods: The statistical programming language R and the framework Shiny were used to develop a platform for data entry, monitoring of therapy and scientific data analysis.

Micro- and Macrovascular Effects of Inflammation in Peripheral Artery Disease-Pathophysiology and Translational Therapeutic Approaches.

Inflammation has a critical role in the development and progression of atherosclerosis. On the molecular level, inflammatory pathways negatively impact endothelial barrier properties and thus, tissue homeostasis. Conformational changes and destruction of the glycocalyx further promote pro-inflammatory pathways also contributing to pro-coagulability and a prothrombotic state.

Predicting HPV association using deep learning and regular H&E stains allows granular stratification of oropharyngeal cancer patients.

Human Papilloma Virus (HPV)-associated oropharyngeal squamous cell cancer (OPSCC) represents an OPSCC subgroup with an overall good prognosis with a rising incidence in Western countries. Multiple lines of evidence suggest that HPV-associated tumors are not a homogeneous tumor entity, underlining the need for accurate prognostic biomarkers. In this retrospective, multi-institutional study involving 906 patients from four centers and one database, we developed a deep learning algorithm (OPSCCnet), to analyze standard H&E stains for the calculation of a patient-level score associated with prognosis, comparing it to combined HPV-DNA and p16-status.

Toll-like Receptors as Pro-Thrombotic Drivers in Viral Infections: A Narrative Review.

Toll-like receptors (TLRs) have a critical role in the pathogenesis and disease course of viral infections. The induced pro-inflammatory responses result in the disturbance of the endovascular surface layer and impair vascular homeostasis. The injury of the vessel wall further promotes pro-thrombotic and pro-coagulatory processes, eventually leading to micro-vessel plugging and tissue necrosis.

Overlap syndrome of anti-aquaporin 4 positive neuromyelitis optica spectrum disorder and primary Sjögren's syndrome: a systematic review of individual patient data.

Central nervous system (CNS) involvement can occur in primary Sjögren's syndrome (pSS) due to co-existing neuromyelitis optica spectrum disorder (NMOSD) which has a highly relapsing course requiring indefinite immunosuppression, and if not diagnosed early, damage accrual occurs over time leading to permanent disability and morbidity. In this review, we describe and outline the clinical course and outcomes of anti-aquaporin 4 (AQP4) antibody seropositive NMOSD with pSS overlap cases. To investigate the co-existence of AQP4 + NMOSD with pSS, we conducted a review of individual patient data from case reports and case series found in major databases.

Overlap syndrome of anti-aquaporin-4 positive neuromyelitis optica spectrum disorder and systemic lupus erythematosus: A systematic review of individual patient data.

Background: Neurological involvement can occur in systemic lupus erythematosus (SLE) due to co-existing neuromyelitis optica spectrum disorder (NMOSD). The symptoms can mimic those of neuropsychiatric manifestations of SLE. Pathogenic anti-aquaporin-4 (AQP4) antibodies, commonly found in NMOSD, are responsible for the neuroinflammatory response and secondary demyelinating lesions.

Harmonization of criteria and terminology in fetal rat skeletal evaluations.

Background: A survey of laboratories in North American and Europe that routinely conduct fetal skeletal examinations was performed with the purpose of (1) understanding current terminology used for classifying skeletal findings in developmental toxicity (DT) studies and (2) understanding the criteria used to identify relatively common findings that sufficiently deviate from normal. The goal was to promote terminology harmonization and improve interlaboratory consistency in the criteria used to identify developmental anomalies.

Methods: The survey, designed based on terminology for developmental anomalies recommended by an international collaboration (Makris et al.

Vitamin K1 and progression of cardiovascular calcifications in hemodialysis patients: the VitaVasK randomized controlled trial.

Background: Cardiovascular calcifications are prevented by matrix Gla protein (MGP), a vitamin K-dependent protein. Haemodialysis patients exhibit marked vitamin K deficiency. The randomized, prospective, open-label, multicentre VitaVasK trial analysed whether vitamin K1 supplementation reduces progression of coronary artery calcifications (CACs) and thoracic aortic calcifications (TACs).

Comparison of two doses of leucovorin in severe low-dose methotrexate toxicity - a randomized controlled trial.

Background: Leucovorin (folinic acid) is a commonly used antidote for severe toxicity with low-dose methotrexate, but its optimum dose is unclear, varying from 15 to 25 mg every 6-h.

Methods: Open-label RCT included patients with severe low-dose (≤ 50 mg/week) methotrexate toxicity defined as WBC ≤ 2 × 10^9/L or platelet ≤ 50 × 10^9/L and randomized them to receive either usual (15 mg) or high-dose (25 mg) intravenous leucovorin given every 6-h. Primary outcome was mortality at 30-days and secondary outcomes were hematological recovery and mucositis recovery.

Interesting rare case of polyarteritis nodosa related to hepatitis B virus and plasma exchange role? - A case report and review of the literature.

Immune-mediated diseases wherein immune complex-mediated injury is predominant; plasma exchange remains a therapeutic option for vasculitis. Hepatitis B virus-associated polyarteritis nodosa (HBV-PAN) wherein immunosuppressants can be contraindicated, plasma exchanges have a proven role when combined with antiviral therapy. Plasma exchange by hastening the clearance of immune complexes is beneficial in acute organ dysfunction.

Objectives: To investigate trial completion and publication rate of cancer trials conducted within the Swiss Group for Clinical Cancer Research (SAKK).

Design: Cohort study of clinical trials.

Microvascular Thrombosis as a Critical Factor in Severe COVID-19.

Platelet-endothelial interactions have a critical role in microcirculatory function, which maintains tissue homeostasis. The subtle equilibrium between platelets and the vessel wall is disturbed by the coronavirus disease 2019 (COVID-19), which affects all three components of Virchow's triad (endothelial injury, stasis and a hypercoagulable state). Endotheliitis, vasculitis, glycocalyx degradation, alterations in blood flow and viscosity, neutrophil extracellular trap formation and microparticle shedding are only few pathomechanisms contributing to endothelial damage and microthrombosis resulting in capillary plugging and tissue ischemia.
