Lactic Acidosis in the Presence of Glucose Diminishes Warburg Effect in Lung Adenocarcinoma Cells.

Front Oncol 2020 12;10:807. Epub 2020 Jun 12.

Department of Chronic-Degenerative Diseases, National Institute of Respiratory Diseases "Ismael Cosío Villegas", Mexico City, Mexico.

Lactic acidosis (3 to 40 mM, pH < 6.9) is a condition found in solid tumors because tumor cells have a high rate of glucose consumption and lactate production even in the presence of oxygen; nevertheless, the microenvironment might still provide a sufficient glucose supply. Lactic acidosis has been proposed to shift metabolism from aerobic glycolysis toward oxidative phosphorylation (OXPHOS). Read More

Ultrasound-responsive alkaline nanorobots for the treatment of lactic acidosis-mediated doxorubicin resistance.

Nanoscale 2020 Jul;12(25):13801-13810

National Laboratory of Solid State Microstructures, Chemistry and Biomedicine Innovation Center, College of Engineering and Applied Sciences, Jiangsu Key Laboratory of Artificial Functional Materials, Nanjing University, 210093, Nanjing, China.

Lactic acidosis is one of the key characteristics of the tumor microenvironment (TME), and plays a critical role in therapy resistance, making it an attractive target for enhancing anticancer treatment. However, no effective systems exhibit the ability to selectively neutralize tumor lactic acidosis in a controlled manner. Here, we have developed novel ultrasound-responsive alkaline nanorobots (AN-DSP), composed of PLGA nanoparticles containing doxorubicin (DOX), sodium carbonate (Na2CO3) and perfluorocarbon (PFC), for recovering from lactic acidosis-mediated drug resistance.

[Management of patients with MELAS syndrome : A case report and general characteristics from an anesthesiological perspective].

Anaesthesist 2020 May 18. Epub 2020 May 18.

Klinik für Anästhesiologie, Universitätsklinikum Düsseldorf, Moorenstr. 5, 40225, Düsseldorf, Deutschland.

Background: Mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome is a rare progressive disease with acute neurological episodes caused by a mitochondriopathy. Due to a defect of oxidative phosphorylation in the respiratory chain, there is impaired mitochondrial energy production with subsequent lactic acidosis, especially in situations with increased stress. Due to the high risk of metabolic derailment MELAS syndrome is a great challenge with respect to the perioperative management of anesthesia. Read More

COVID-19 in diabetic patients: Related risks and specifics of management.

Ann Endocrinol (Paris) 2020 Jun 12;81(2-3):101-109. Epub 2020 May 12.

Department of internal medicine, Cliniques Universitaires Saint-Luc, avenue Hippocrate 10, 1200 Brussels, Belgium.

Diabetes is among the most frequently reported comorbidities in patients infected with COVID-19. According to current data, diabetic patients do not appear to be at increased risk of contracting SARS-CoV-2 compared to the general population. On the other hand, diabetes is a risk factor for developing severe and critical forms of COVID-19, the latter requiring admission to an intensive care unit and/or use of invasive mechanical ventilation, with high mortality rates.

Vascular and metabolic effects of metformin added to insulin therapy in patients with type 1 diabetes: A systematic review and meta-analysis.

Diabetes Metab Res Rev 2020 May 10:e3334. Epub 2020 May 10.

Shenzhen Hospital, Southern Medical University, Shenzhen, China.

Background: The incidence of type 1 diabetes mellitus (T1DM) is increasing among youth worldwide, translating to an increased risk ofearly-onset cardiovascular disease (CVD). Mounting studies have shown that metformin may reduce maximal carotidintima-media thickness (cIMT), improve insulin resistance and metabolic control in subjects with T1DM, and thus, may extend cardioprotective benefits. This systematic review and meta-analysis was performed to assess the efficacy and safety of metformin added to insulin therapy on reducing CVD risks and improving metabolism in T1DM. Read More
