#Hydrating the respiratory tract: an alternative explanation why masks lower severity of #COVID-19
https://2medical.news/2021/02/22/hydrating-the-respiratory-tract-an-alternative-explanation-why-masks-lower-severity-of-covid-19/
The seasonality of respiratory diseases has been linked, among other factors, to low outdoor absolute humidity and low indoor relative humidity, which increase evaporation of water in the mucosal lining of the respiratory tract. We demonstrate that normal breathing results in an absorption-desorption cycle inside facemasks, in which supersaturated air is absorbed by the mask fibers during expiration, followed by evaporation during inspiration of dry …
Early peripheral activity alters nascent subplate circuits in the #auditory cortex
https://2medical.news/2021/02/21/early-peripheral-activity-alters-nascent-subplate-circuits-in-the-auditory-cortex/
Cortical function can be shaped by sensory experience during a critical period. The onset of the critical period is thought to coincide with the onset of thalamocortical transmission to the thalamo-recipient layer 4 (L4). In early development, subplate neurons (SPNs), and not L4 neurons, are the first targets of thalamic afferents. SPNs are transiently involved in early development and are largely eliminated during development. Activation …
#Pain and fatigue are longitudinally and bi-directionally associated with more #sedentary time and less standing time in #rheumatoid arthritis
https://2medical.news/2021/02/19/pain-and-fatigue-are-longitudinally-and-bi-directionally-associated-with-more-sedentary-time-and-less-standing-time-in-rheumatoid-arthritis/
The aims of this study were to examine the longitudinal and bi-directional associations of pain and fatigue with sedentary, standing and stepping time in RA.

#SARS-CoV-2 infection is effectively treated and prevented by EIDD-2801
https://2medical.news/2021/02/17/sars-cov-2-infection-is-effectively-treated-and-prevented-by-eidd-2801/
All known recently emerged human coronaviruses probably originated in bats1. Here we used a single experimental platform based on human lung-only mice (LoM) to demonstrate efficient in vivo replication of all recently emerged human coronaviruses (SARS-CoV, MERS-CoV and SARS-CoV-2) and two highly relevant endogenous pre-pandemic SARS-like bat coronaviruses. Virus replication in this model occurs in bona fide human lung tissue and does not require any …
An integrative study of five biological #clocks in somatic and mental #health
https://2medical.news/2021/02/16/an-integrative-study-of-five-biological-clocks-in-somatic-and-mental-health/
Biological clocks have been developed at different molecular levels and were found to be more advanced in the presence of somatic illness and mental disorders. However, it is unclear whether different biological clocks reflect similar aging processes and determinants. In ~3000 subjects, we examined whether five biological clocks (telomere length, epigenetic, transcriptomic, proteomic, and metabolomic clocks) were interrelated and associated to somatic and mental health …

Quantifying asymptomatic infection and transmission of #COVID-19 in New York City using observed cases, serology, and testing capacity
https://2medical.news/2021/02/14/quantifying-asymptomatic-infection-and-transmission-of-covid-19-in-new-york-city-using-observed-cases-serology-and-testing-capacity/
The contributions of asymptomatic infections to herd immunity and community transmission are key to the resurgence and control of COVID-19, but are difficult to estimate using current models that ignore changes in testing capacity. Using a model that incorporates daily testing information fit to the case and serology data from New York City, we show that the proportion of symptomatic cases is low, ranging from …
Once-Weekly #Semaglutide in Adults with Overweight or #Obesity
https://2medical.news/2021/02/13/once-weekly-semaglutide-in-adults-with-overweight-or-obesity/
Obesity is a global health challenge with few pharmacologic options. Whether adults with obesity can achieve weight loss with once-weekly semaglutide at a dose of 2.4 mg as an adjunct to lifestyle intervention has not been confirmed. METHODS In this double-blind trial, we enrolled 1961 adults with a body-mass index (the weight in kilograms divided by the square of the height in meters) of 30 …

#Nanoparticle-Mediated Delivery of 2-Deoxy-D-Glucose Induces Antitumor Immunity and Cytotoxicity in #Liver Tumors in Mice
https://2medical.news/2021/02/10/nanoparticle-mediated-delivery-of-2-deoxy-d-glucose-induces-antitumor-immunity-and-cytotoxicity-in-liver-tumors-in-mice/
Immune checkpoint inhibitors have shed light on the importance of antitumor immunity as a therapeutic strategy for hepatocellular carcinoma (HCC). The altered glucose metabolism known as the Warburg effect recently has gained attention as a cancer immune-resistance mechanism. Considering glycolysis inhibitors as therapeutic agents, their specific delivery to cancer cells is critical not to induce adverse effects. Thus, we investigated antitumor effects of a glycolysis …
Incidence of adverse #cardiovascular events in type 2 #diabetes mellitus patients after initiation of glucose‐lowering agents: A population‐based community study from the Shizuoka Kokuho database

Increased incidence of hospitalization for heart failure (HHF) among patients with diabetes is increasingly being reported. We investigated the incidence of adverse cardiovascular events including HHF among patients with type 2 diabetes mellitus, and the potential clinical improvement with sodium–glucose cotransporter 2 inhibitors (SGLT2i) using a contemporary administrative claims database from a large governmental district of Japan. We included initiators of any oral glucose‐lowering drugs …

Objective To investigate the incidence of diabetic ocular complications in patients with type 2 diabetes after GBP compared with the incidence of diabetic ocular complications in a matched cohort of patients with obesity and diabetes who have …
NAD+ depletion by type I interferon signaling sensitizes #pancreatic cancer cells to NAMPT inhibition
https://2medical.news/2021/02/20/nad-depletion-by-type-i-interferon-signaling-sensitizes-pancreatic-cancer-cells-to-nampt-inhibition/
Emerging evidence suggests that intratumoral interferon (IFN) signaling can trigger targetable vulnerabilities. A hallmark of pancreatic ductal adenocarcinoma (PDAC) is its extensively reprogrammed metabolic network, in which nicotinamide adenine dinucleotide (NAD) and its reduced form, NADH, are critical cofactors. Here, we show that IFN signaling, present in a subset of PDAC tumors, substantially lowers NAD(H) levels through up-regulating the expression of NAD-consuming enzymes PARP9, PARP10, …

Epidemiologic evidence regarding association of ovarian cancer risk with blood lipid level and hyperlipidemia is inconsistent. We aimed to synthesize available epidemiologic studies to disentangle associations of cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and hyperlipidemia with ovarian cancer risk. We searched PubMed, EMBASE, and Web of Science for eligible studies. A random-effects model was applied for synthesis. Heterogeneity was evaluated by …

https://2medical.news/2021/02/09/finger-joint-cartilage-evaluated-by-semiquantitative-ultrasound-score-in-patients-with-rheumatoid-arthritis/
Joint destruction in rheumatoid arthritis (RA) includes both bone and cartilage lesions. Since joint space narrowing (JSN) is not a direct evaluation of cartilage using radiography, we aimed to examine the validity of ultrasound (US) cartilage evaluation using a semiquantitative method in patients with RA. Methods We enrolled 103 patients with RA who were in remission or showing low disease activity and 42 healthy subjects. …
