The Kilauea Eruption Has People Worried About Volcanic Smog. Here ’s How Dangerous ‘Vog’ Really Is

Thinking of Hawaii typically brings to mind pristine white-sand beaches and crystal-clear seas. In contrast to these picturesque scenes, however, is the Kilauea Volcano, situated on the state’s Big Island, which saw a major explosion this week and has some reports warning of a volcanic smog (or “vog”). Since it started continuously erupting in 1983, Kilauea has each day pumped out at least 300 metric tons of sulfur dioxide gas, a pollutant also produced by power plants and industrial manufacturing operations. Over the course of a year, Kilauea’s sulfur dioxide production is equivalent to somewhere between 5% and 10% of that emitted by all of China, according to a 2016 paper published in Environment International. And after a major eruption like the one that occurred last week, production kicks into overdrive. “These are really high levels, and that’s why [people near the volcano had to] evacuate,” says Dr. Elizabeth Tam, a professor of medicine and respiratory health at the University of Hawaii’s John A. Burns School of Medicine and the lead author of the Environment International paper. “But I have to say that, periodically, many places on the Big Island actually see levels that are way over what [the Environmental Protection Agency] considers safe.” Sulfur dioxide is toxic on its own, but it also reacts with moisture, oxygen, dust and sunlight in the atmosphere to create volcanic smog, or “vog,” accord...

Abstract Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are important causes of hospital admission and mortality. Pneumonia is a major contributor to hospitalization for AECOPD and has a close relationship with poor outcomes. We performed a prospective cohort study to evaluate the prognosis of AECOPD patients with or without community-acquired pneumonia (CAP) who hospitalized from January 2012 to December 2015. We investigated mortality and readmission rates within 6 months after the first admission between two groups and analyzed the difference of survival rate according to readmission dura...

This study compared the effect of a virtual laboratory, a living tissue laboratory, and a blended laboratory on student learning about the generation and conduction of neural action potentials and perceptions about life science. Sixty-three second-year medical students were randomly assigned to one of three groups (living tissue laboratory, virtual laboratory, and blended group). The students conducted the practical activity, and then they were given a postlaboratory quiz and an attitude survey. The blended group euthanized fewer animals and spent less time to finish the animal experiment than the living tissue group did. ...

Abstract The rapid development of mobile phones and communication networks is profoundly changing the lives of people in China. With the gradual growth of Wi-Fi on college and university campuses, Chinese schools are setting off a wave of teaching reform combining online material with traditional classroom instruction. We adapted a Chinese University massive open online course physiology course into a private university online course, specifically designed for second-semester bachelor's level nursing students at Taishan Medical University. This online course blended with classroom teaching was offered to 108 fresh...

We developed an efficient MCI-gel-based method to purify BCE from C. longa, and established BCE fragmentation pathways under ESI-MS/MS. The abundances of BCE curcumin, demethoxycurcumin, and bi...

Objectives: To identify, appraise, and synthesize current evidence to determine whether early enteral nutrition alters patient outcomes from major burn injury. Data Sources: Medline, Embase, and the China National Knowledge Infrastructure were searched. The close out date was May 1, 2018. Study Selection: Early enteral nutrition was defined as a standard formula commenced within 24 hours of injury or admission to ICU or burn unit. Comparators included any form of nutrition support “except” early enteral nutrition. Only randomized controlled trials reporting patient-centered outcomes were eligible for in...

Conclusions: Despite massive blood transfusion, including very old blood, the duration of red cell storage did not influence outcome in burn patients. Provision of the oldest blood first by Blood Banks is rational, even for massive transfusion.

Objectives: Subarachnoid hemorrhage is a life-threatening disease associated with high mortality and morbidity. A substantial number of patients develop systemic inflammatory response syndrome. We aimed to identify risk factors for systemic inflammatory response syndrome development and to evaluate the role of systemic inflammatory response syndrome on patients’ outcome. Design: Retrospective observational cohort study of prospectively collected data. Setting: Neurocritical care unit at a tertiary academic medical center. Patients: Two-hundred and ninety-seven consecutive nontraumatic subarachnoid hemorrha...

In this study, we innovatively used the Deinagkistrodon acutus (D. acutus) venom model as well as the classical haemorrhagic animal model to evaluate the haemostatic bioactivity of SSC-CDs. The results indicated that SSC-CDs had outstanding haemostatic bioactivity and might inhibit the haemorrhagic activity via PLT elevation. According to the results of this study and our previous work, we discovered that CDs derived from different kinds of charcoal drugs presented similarities and differences in the structural feature, physicochemical property and bioactivity. In order to further explore the self-bioactivities, we first n...

CONCLUSIONS: These findings show that a considerable proportion of patients with severe asthma remain uncontrolled and are not eligible for any of the available biological treatments. This underlines the need for therapeutic innovations in this disease. PMID: 30429093 [PubMed - as supplied by publisher]
