The association between air pollution and COVID-19 related mortality in Santiago, Chile: A daily time series analysis.

Environ Res

July 2021

Population Studies Division, Environmental Health Science & Research Bureau, Health Canada, Canada. Electronic address:

Background: Exposure to ambient air pollution is a risk factor for morbidity and mortality from lung and heart disease.

Research Question: Does short term exposure to ambient air pollution influence COVID-19 related mortality?

Study Design And Methodology: Using time series analyses we tested the association between daily changes in air pollution measured by stationary monitors in and around Santiago, Chile and deaths from laboratory confirmed or suspected COVID-19 between March 16 and August 31, 2020. Results were adjusted for temporal trends, temperature and humidity, and stratified by age and sex.

Introduction: Systemic chronic low-grade inflammation has been linked to insulin resistance (IR) and non-alcoholic steatohepatitis (NASH). NOD-like receptor protein 3 (NLRP3) inflammasome and its final product, interleukin (IL)-1β, exert detrimental effects on insulin sensitivity and promote liver inflammation in murine models. Evidence linking hepatic NLRP3 inflammasome, systemic IR and NASH has been scarcely explored in humans.

Introduction: There is extensive evidence associating the response to neoadjuvant chemotherapy (NeoCT) with breast cancer (BC) survival. However, to the author's knowledge, there is no published data in Chile. The objective of the study is to evaluate whether achieving pathological complete response (pCR) after NeoCT is associated with greater survival and lower risk of recurrence in a Chilean Public Health Service.

Obstructive sleep apnea syndrome affects 1%-4% of all children worldwide. Currently, diagnosis of obstructive sleep apnea is based on sea-level guidelines, without taking into account the altitude at which the populations live. It has been shown that at 3,200 m of altitude there is an increase in obstructive events in healthy children aged 7 to 16 years; on the other hand, it is known that SpO dispersion between individuals becomes wider as altitude increases, a phenomenon that is more marked during sleep.

Article Synopsis
  • A study was conducted to create and validate a model that can predict seizure freedom in children undergoing hemispheric surgery for drug-resistant epilepsy, analyzing data from 1267 surgeries across 32 centers globally.
  • The results showed that 66% of patients achieved seizure freedom 3 months post-surgery, with a predictive model developed using factors like age at seizure onset and imaging results, achieving a moderately high predictive accuracy (area under the curve = .72).
  • The study introduced the Hemispheric Surgery Outcome Prediction Scale (HOPS), which helps identify children who will benefit from surgery and informs medical decisions, potentially avoiding unnecessary surgeries for those unlikely to gain seizure control.

Introduction: Palliative gastrojejunostomy is a surgical technique that allows restoration of oral intake among patients with gastric outlet obstruction (GOO) caused by unresectable neoplasms. Research suggests standard treatment for malignant GOO should be laparoscopic gastrojejunostomy (LGJ). This study presents the clinical outcomes of palliative gastrojejunostomy and compares results from LGJ and open gastrojejunostomy (OGJ) at our centre.

Although empirical evidence may provide a much desired sense of certainty amidst a pandemic characterised by uncertainty, the vast gamut of available COVID-19 data, including misinformation, has instead increased confusion and distrust in authorities' decisions. One key lesson we have been gradually learning from the COVID-19 pandemic is that the availability of empirical data and scientific evidence alone do not automatically lead to good decisions. Good decision-making in public health policy, this paper argues, does depend on the availability of reliable data and rigorous analyses, but depends above all on sound ethical reasoning that ascribes value and normative judgement to empirical facts.

Ingestion of food activates a cascade of endocrine responses (thereby reflecting a contemporaneous feeding status) that include the release of hormones from the gastrointestinal (GI) tract, such as cholecystokinin (CCK), glucagonlike peptide YY (PYY), peptide PP, and oleoylethanolamide, as well as suppression of ghrelin secretion. The pancreas and adipose tissue, on the other hand, release hormones that serve as a measure of the current metabolic state or the long-term energy stores, that is, insulin, leptin, and adiponectin. It is well known and intuitively understandable that these hormones target either directly (by crossing the blood-brain barrier) or indirectly (e.

Cocaine not only increases brain dopamine levels but also activates the sigma receptor (σ R) that in turn regulates orexigenic receptor function. Identification of interactions involving dopamine D (D R), ghrelin (GHS-R ), and σ receptors have been addressed by biophysical techniques and a complementation approach using interfering peptides. The effect of cocaine on receptor functionality was assayed by measuring second messenger, cAMP and Ca , levels.

Availability of the essential macronutrient nitrogen in soil plays a critical role in plant growth, development, and impacts agricultural productivity. Plants have evolved different strategies for sensing and responding to heterogeneous nitrogen distribution. Modulation of root system architecture, including primary root growth and branching, is among the most essential plant adaptions to ensure adequate nitrogen acquisition.

Previous research has found association between antisocial behavior and deficits in executive functioning. However, research into a link between them accounting for criminal history has found divergent results in western countries. The present study sought to determine the severity of executive functioning deficits in offenders compared to a normative sample, and the differences between first time offenders as compared to recidivists in Uruguay using a cross-sectional design.

Introduction: Lactic acidosis after cardiac surgery with cardiopulmonary bypass is common and associated with an increase in postoperative morbidity and mortality. A number of potential causes for an elevated lactate after cardiopulmonary bypass include cellular hypoxia, impaired tissue perfusion, ischemic-reperfusion injury, aerobic glycolysis, catecholamine infusions, and systemic inflammatory response after exposure to the artificial cardiopulmonary bypass circuit. Our goal was to examine the relationship between early abnormalities in microcirculatory convective blood flow and diffusive capacity and lactate kinetics during early resuscitation in the intensive care unit.

Canine osteosarcoma checkpoint expression correlates with metastasis and T-cell infiltrate.

Vet Immunol Immunopathol

February 2021

Department of Small Animal Clinical Sciences, College of Veterinary Medicine, University of Florida, PO Box 100126, 2015 SW 16th Ave, Gainesville, FL, 32610-0126, United States.

Background: Immune-targeted therapies are being successfully implemented into cancer clinical practice. In particular checkpoint inhibitors are employed to modulate the immune microenvironment of solid tumors. We sought to determine the expression of PD-L1, HVEM, and B7H3 in human and canine osteosarcoma, and correlate expression with clinical features and tumor infiltrating lymphocytes in naturally-occurring canine osteosarcoma.

Background Varicella-zoster virus (VZV) and herpes zoster cause infections of the central nervous system (CNS) manifesting as meningitis or encephalitis. As compared to enterovirus (EV) and herpes simplex virus 1 (HSV-1) and 2 (HSV-2), it is not often tested in CNS infections due to VZV and herpes zoster. There is a certain tendency to think that the findings in the cerebrospinal fluid in infections of the CNS by viruses are comparable among themselves.
