Novel Antidiabetic Strategies and Diabetologists' Views in Nonalcoholic Steatohepatitis.

Semin Liver Dis 2021 Jul 21. Epub 2021 Jul 21.

Institute for Clinical Diabetology, German Diabetes Center, Leibniz Center for Diabetes Research at Heinrich-Heine-University Düsseldorf, Düsseldorf, Germany.

Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide with high prevalence, especially in individuals with obesity and type 2 diabetes. Among individuals with type 2 diabetes, the severe insulin resistant subgroup has the greatest risk of NAFLD, likely due to dysfunctional adipose tissue mass but also genetic factors, and may progress earlier to inflammatory and profibrotic nonalcoholic steatohepatitis (NASH). NASH has been associated with increased liver-related as well as cardiovascular morbidity and mortality. Read More

Making sense of "buzzword" as a term through co-occurrences analysis.

Heliyon 2021 Jun 4;7(6):e07208. Epub 2021 Jun 4.

Peoples' Friendship University of Russia (RUDN University), 6 Miklukho-Maklay Str., Moscow, Russian Federation.

The study argues that while the existing research on buzzwords mainly involves the functional and pragmatic analysis of their individual specimen, such as "engagement", "synergy" or "development", an alternative approach can be implemented to look into the nature and immediate implications behind the term in question. The suggested approach involves investigating the occurrences of the term proper as opposed to analysing individual buzzwords. The authors hypothise and demonstrate that linguistic context of the term "buzzword", i. Read More

Unifying Concepts in Electro- and Thermocatalysis toward Hydrogen Peroxide Production.

J Am Chem Soc 2021 Jun 21;143(21):7940-7957. Epub 2021 May 21.

Department of Chemical and Biomolecular Engineering, University of Illinois at Urbana-Champaign, Urbana, Illinois 61801, United States.

We examine relationships between HO and HO formation on metal nanoparticles by the electrochemical oxygen reduction reaction (ORR) and the thermochemical direct synthesis of HO. The similar mechanisms of such reactions suggest that these catalysts should exhibit similar reaction rates and selectivities at equivalent electrochemical potentials (μ̅), determined by reactant activities, electrode potential, and temperature. We quantitatively compare the kinetic parameters for 12 nanoparticle catalysts obtained in a thermocatalytic fixed-bed reactor and a ring-disk electrode cell. Read More

Visual Influences on Auditory Behavioral, Neural, and Perceptual Processes: A Review.

J Assoc Res Otolaryngol 2021 May 20. Epub 2021 May 20.

Vanderbilt Brain Institute, Vanderbilt University, Nashville, TN, USA.

In a naturalistic environment, auditory cues are often accompanied by information from other senses, which can be redundant with or complementary to the auditory information. Although the multisensory interactions derived from this combination of information and that shape auditory function are seen across all sensory modalities, our greatest body of knowledge to date centers on how vision influences audition. In this review, we attempt to capture the state of our understanding at this point in time regarding this topic. Read More

Respir Care 2021 May 10. Epub 2021 May 10.

Department of Anesthesia and Perioperative Care. University of California, San Francisco at Zuckerberg San Francisco General Hospital and Trauma Center, San Francisco, California.

Corona virus disease 2019 (COVID-19) represents the greatest medical crisis encountered in the young history of critical care and respiratory care. During the early months of the pandemic, when little was known about the virus, the acute hypoxemic respiratory failure it caused did not appear to fit conveniently or consistently into our classification of acute respiratory distress syndrome (ARDS). This not only re-ignited a half-century's long simmering debate over taxonomy, but also fueled similar debates over how PEEP and lung-protective ventilation should be titrated, as well as the appropriate role of non-invasive ventilation in ARDS.

Using an Information Package to Reduce Patients' Risk of Renal Damage: Protocol for a Randomized Feasibility Trial.

JMIR Res Protoc 2021 Apr 30;10(4):e29161. Epub 2021 Apr 30.

Department of General Practice and Rural Health, Otago Medical School - Dunedin Campus, University of Otago, Dunedin, New Zealand.

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) are a common cause of renal damage, especially when taken together with angiotensin-converting enzyme inhibitors (ACE-i) or angiotensin II receptor blockers (ARBs) plus a diuretic - a combination known as the "triple whammy." New Zealand patients are at high risk of the "triple whammy" because they can easily purchase NSAIDs without a prescription and in nonpharmacy retail settings (eg, the supermarket), there is no legal requirement to include patient information sheets with medication, and direct-to-consumer drug advertising is permitted. A patient information package has been developed for those at greatest risk of the "triple whammy," consisting of a printable PDF and an interactive online learning activity. Read More
