Lung donation following SARS-CoV-2 infection.

Am J Transplant 2021 Jul 31. Epub 2021 Jul 31.

Division of Thoracic Surgery, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA.

There have been over 177 million cases of COVID-19 worldwide, many of whom could be organ donors. Concomitantly, there is an anticipated increase in the need for donor lungs due to expanding indications. Given that the respiratory tract is most commonly affected by COVID-19, there is an urgent need to develop donor assessment criteria while demonstrating safety and "efficacy" of lung donation following COVID-19 infection.

Translation and cross-cultural adaptation of the Clinical Care Classification system.

Int J Med Inform 2021 Jul 16;153:104534. Epub 2021 Jul 16.

Saint Camillus International University of Health Sciences, Via di Sant'Alessandro 8, Rome 00131, Italy.

Introduction: The Clinical Care Classification (CCC) system is one of the standard nursing terminologies recognized by the American Nurses Association, developed to describe nursing care through electronic documentation in different healthcare settings. The translation of the CCC system into languages other than English is useful to promote its widespread use in different countries and to provide the standard nursing data necessary for interoperable health information exchange. The aim of this study was to translate the CCC system from English to Italian and to test its clinical validity. Read More

Endocytosis of peroxiredoxin 1 links sterile inflammation to immunoparalysis in pediatric patients following cardiopulmonary bypass.

Redox Biol 2021 Jul 28;46:102086. Epub 2021 Jul 28.

Graduate Institute of Clinical Medicine, College of Medicine, National Taiwan University, Taipei, Taiwan; Department of Internal Medicine, National Taiwan University Hospital, Taiwan; Center of Precision Medicine, College of Medicine, National Taiwan University, Taiwan. Electronic address:

After cardiopulmonary bypass (CPB), the occurrence of systemic inflammatory response is often accompanied by a persistent compensatory anti-inflammatory response syndrome that can lead to a compromised immune competence termed immunoparalysis, rendering the patients susceptible to infections which is a leading complication following cardiac surgery. However, the underlying mechanisms of CPB-elicited immunoparalysis remain obscure. In this study we showed that peroxiredoxin 1 (Prdx1), a putative cytosolic antioxidant, was released immediately after CPB in a cohort of pediatric patients receiving congenital cardiac surgery.

Clin Res Hepatol Gastroenterol 2021 Jul 28:101767. Epub 2021 Jul 28.

Service d'hépatologie, Hôpital Rangueil, CHU Toulouse, Toulouse.

Compensated advanced chronic liver disease (cACLD) describes the spectrum of advanced fibrosis/cirrhosis in asymptomatic patients at risk of developing clinically significant portal hypertension (CSPH, defined by a hepatic venous pressure gradient (HVPG) ≥10 mmHg). Patients with cACLD are at high risk of liver-related morbidity and mortality. In patients at risk of chronic liver disease, cACLD is strongly suggested by a liver stiffness (LSM) value >15 kPa or clinical/biological/radiological signs of portal hypertension, and ruled out by LSM <10 kPa, or Fibrotest® ≤0.

Inkk Trial - Intraoperative ketamine for perioperative pain management following total knee endoprosthetic replacement in oncology: a double-blinded randomized trial.

Braz J Anesthesiol 2021 Jul 28. Epub 2021 Jul 28.

Tata Memorial Hospital and Homi Bhabha National Institute, Department of Physiotherapy, Mumbai, India.

Background: There has been a growing interest in the use of ketamine following orthopedic surgeries. We hypothesized that low dose intravenous ketamine during surgery would help in mobilization following total knee replacement (TKR) in oncology patients as assessed by the timed to up and go (TUG) test at 72 hours post-surgery. Our secondary objectives were to compare the opioid requirement at end of 72 hours, pain scores, satisfaction with pain management, adverse effects, range of joint movement achieved in the post-operative period and the functional recovery at the end of 1 month.

The relationship between diabetes and surgical site infection following coronary artery bypass graft surgery in current-era models of care.

J Hosp Infect 2021 Jul 28. Epub 2021 Jul 28.

Department of Diabetes and Endocrinology, Royal Melbourne Hospital; Department of Medicine, Royal Melbourne Hospital, University of Melbourne.

Background: Although diabetes is a recognised risk factor for post-operative infections, the seminal Portland Diabetic Project studies in cardiac surgery demonstrated intravenous insulin infusions following open-cardiac surgery achieved near normal glycaemia and decreased deep sternal wound infection to similar rates to those without diabetes.

Aim: We sought to examine a contemporary cohort of patients undergoing coronary artery bypass graft surgery (CABGS) to evaluate the relationship between diabetes, hyperglycaemia and risk of surgical site infection (SSI) in current-era models of care.

Methods: Consecutive patients who underwent CABGS between 2016 and 2018 were identified through a state-wide data repository for healthcare-associated infections. Read More

Hypothermia Promotes Mitochondrial Elongation In Cardiac Cells Via Inhibition Of Drp1.

Cryobiology 2021 Jul 28. Epub 2021 Jul 28.

Cedars-Sinai Smidt Heart Institute, Barbra Streisand Women's Heart Center, Cedars-Sinai Medical Center, Los Angeles, California, USA.

Hypothermia is a valuable clinical tool in mitigating against the consequences of ischemia in surgery, stroke, cardiac arrest and organ preservation. Protection is afforded principally by a reduction of metabolism, manifesting as reduced rates of oxygen uptake, preservation of ATP levels, and a curtailing of ischemic calcium overload. The effects of non-ischemic hypothermic stress are relatively unknown. Read More

Gustave Roussy Cancer Campus, Villejuif, France; Institut National de la Santé Et de la Recherche Médicale (INSERM) U1015, Equipe Labellisée-Ligue Nationale contre le Cancer, Villejuif, France.

Mononuclear phagocytes (MNPs) encompass dendritic cells, monocytes, and macrophages (MoMac), which exhibit antimicrobial, homeostatic, and immunoregulatory functions. We integrated 178,651 MNPs from 13 tissues across 41 datasets to generate a MNP single-cell RNA compendium (MNP-VERSE), a publicly available tool to map MNPs and define conserved gene signatures of MNP populations. Next, we generated a MoMac-focused compendium that revealed an array of specialized cell subsets widely distributed across multiple tissues. Read More

Early diagnosis of fibrotic interstitial lung disease: challenges and opportunities.

Lancet Respir Med 2021 Jul 28. Epub 2021 Jul 28.

Department of Respiratory Medicine, National Reference Coordinating Centre for Rare Pulmonary Diseases, Louis Pradel Hospital, Hospices Civils de Lyon, Lyon, France; Department of Respiratory Medicine, Université de Lyon, Université Claude Bernard Lyon 1, UMR754, IVPC, Lyon, France.

Many patients with interstitial lung disease (ILD) develop pulmonary fibrosis, which can lead to reduced quality of life and early mortality. Patients with fibrotic ILD often have considerable diagnostic delay, and are exposed to unnecessary and costly diagnostic procedures, and ineffective and potentially harmful treatments. Non-specific and insidious presenting symptoms, along with scarce knowledge of fibrotic ILD among primary care physicians and non-ILD experts, are some of the main causes of diagnostic delay.
