Key toolkits of non-pharmacological management in COPD: during and beyond COVID-19.

Front Biosci (Landmark Ed) 2021 Jul;26(7):246-252

Institute for Liver and Digestive Health, Division of Medicine, University College London, NW3 2PF London, UK.

Individuals with COPD are at higher risk of severe disease and mortality if they contract COVID-19. Shielding and social distancing have negatively impacted the delivery of routine care for COPD patients, which should be maintained to avoid further deterioration. We aimed to review the literature about the key toolkits of non-pharmacological treatments of COPD patients before and during the COVID-19 pandemic. Read More

Nodal tumor volume as a prognostic factor for head and neck squamous cell carcinoma: a systematic review.

Front Biosci (Landmark Ed) 2021 Jul;26(7):235-245

1st Department of Otolaryngology - Head & Neck Surgery, Medical School, National & Kapodistrian University of Athens (NKUA), Hippokrateio Hospital, 11527 Athens, Greece.

: Several studies suggest that there is an association between the metastatic nodal tumor volume and the clinical outcome in patients with solid cancers. However, despite the prognostic potential of nodal volume, a standardized method for estimating the nodal volumetric parameters is lacking. Herein, we conducted a systematic review of the published scientific literature towards investigating the prognostic value of nodal volume in the carcinomas of head and neck, taking into consideration the primary tumor site and the human papillomavirus (HPV) status.

Br J Haematol 2021 Aug 2. Epub 2021 Aug 2.

Department of Leukemia, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Programmed cell death protein 1 (PD-1) and PD-ligand 1 (PD-L1) expression is upregulated in cluster of differentiation 34 (CD34) bone marrow cells from patients with myelodysplastic syndromes (MDS). Hypomethylating agent (HMA) treatment results in further increased expression of these immune checkpoints. We hypothesised that combining an anti-PD-1 antibody with HMAs may have efficacy in patients with MDS. Read More

Br J Haematol 2021 Aug 2. Epub 2021 Aug 2.

Registre des Neutropénies Chroniques, Centre de Référence des Neutropénies Chroniques, Hôpital Trousseau, Assistance Publique-Hôpitaux de Paris (APHP), Paris, France.

Among 143 patients with elastase, neutrophil-expressed (ELANE)-related neutropenia enrolled in the French Severe Chronic Neutropenia Registry, 94 were classified as having severe chronic neutropenia (SCN) and 49 with cyclic neutropenia (CyN). Their infectious episodes were classified as severe, mild or oral, and analysed according to their natural occurrence without granulocyte-colony stimulating factor (G-CSF), on G-CSF, after myelodysplasia/acute leukaemia or after haematopoietic stem-cell transplantation. During the disease's natural history period (without G-CSF; 1913 person-years), 302, 957 and 754 severe, mild and oral infectious events, respectively, occurred. Read More

Elementary Laboratory Assays as Biomarkers of Ageing: Support for Treatment of COVID-19?

Gerontology 2021 Aug 2:1-14. Epub 2021 Aug 2.

Kantonsspital Graubünden, Chur, Switzerland.

Youth, working age and the elderly: On a timeline, chronological age (CA) and biological age (BA) may dissociate; nosological entities manifest themselves at different BAs. In determining which disease corresponds to a given age decade, statistical registries of causes of death are unreliable and this does not change with SARS CoV-2 infection. Beyond adolescence, ageing metrics involve estimations of changes in fitness, including prediction models to estimate the number of remaining years left to live. Read More

Mechanisms of Caloric Restriction-Mediated Stress-Resistance in Acute Kidney Injury.

Nephron 2021 Aug 2:1-5. Epub 2021 Aug 2.

Department II of Internal Medicine and Center for Molecular Medicine Cologne, University of Cologne, Faculty of Medicine and University Hospital Cologne, Cologne, Germany.

Caloric restriction (CR)-mediated organ protection has been shown to be extremely efficient in rodent models of acute kidney injury (AKI). Limited understanding of the underlying mechanisms paired with a risk of malnourishment and feasibility problems has hindered the translation of this immense potential to the patient setting. In this mini-review, the current mechanistic concepts of CR-mediated stress-resistance as potential key targets for renal protection in AKI will be highlighted. Read More

The Future of Parallel Tumor and Germline Genetic Testing: Is There a Role for All Patients With Cancer?

J Natl Compr Canc Netw 2021 Jul 28;19(7):871-878. Epub 2021 Jul 28.

1Clinical Genetics Service, Department of Medicine, Memorial Sloan Kettering Cancer Center, New York, New York.

Under the traditional paradigm of genetic testing in cancer, the role of germline testing was to assess for the inherited risk of cancer, whereas the role of tumor testing was to determine therapeutic selection. Parallel tumor-normal genetic testing uses simultaneous genetic testing of the tumor and normal tissue to identify mutations and allows their classification as either germline or somatic. The increasing adoption of parallel testing has revealed a greater number of germline findings in patients who otherwise would not have met clinical criteria for testing. Read More

Center for Evidence-Based Imaging, Brigham and Women's Hospital, Harvard Medical School, 1620 Tremont Street, Boston, MA 02120, United States of America. Electronic address:

Purpose: To identify patient characteristics associated with screening mammography cancellations and rescheduling during the COVID-19 pandemic.

Methods: Scheduled screening mammograms during three time periods were retrospectively reviewed: state-mandated shutdown (3/17/2020-6/16/2020) during which screening mammography was cancelled, a period of 2 months immediately after screening mammography resumed (6/17/2020-8/16/2020), and a representative period prior to COVID-19 (6/17/2019-8/16/2019). Relative risk of cancellation before COVID-19 and after reopening was compared for age, race/ethnicity, insurance, history of chronic disease, and exam location, controlling for other collected variables.

An adverse outcome pathway based in vitro characterization of novel flame retardants-induced hepatic steatosis.

Environ Pollut 2021 Jul 28;289:117855. Epub 2021 Jul 28.

Faculty of Science, RECETOX, Masaryk University, Kamenice 5, CZ62500, Brno, Czech Republic. Electronic address:

A wide range of novel replacement flame retardants (nFRs) is consistently detected in increasing concentrations in the environment and human matrices. Evidence suggests that nFRs exposure may be associated with disruption of the endocrine system, which has been linked with the etiology of various metabolic disorders, including nonalcoholic fatty liver disease (NAFLD). NAFLD is a multifactorial disease characterized by the uncontrolled accumulation of fats (lipids) in the hepatocytes and involves multiple-hit pathogenesis, including exposure to occupational and environmental chemicals such as organophosphate flame retardants (OPFRs).

CT-defined emphysema in COPD patients and risk for change in desaturation status in 6-min walk test.

Respir Med 2021 Jul 23;187:106542. Epub 2021 Jul 23.

Centre for International Health, Department of Global Public Health and Primary Care, University of Bergen, Bergen, Norway.

Background: Emphysema and exercise induced desaturation (EID) are both related to poorer COPD prognosis. More knowledge of associations between emphysema and desaturation is needed for more efficient disease management.

Research Question: Is emphysema a risk factor for both new and repeated desaturation, and is emphysema of more or less importance than other known risk factors?

Methods: 283 COPD patients completed a 6-min walk test (6MWT) at baseline and one year later in the Bergen COPD cohort study 2006-2011. Read More
