Brain activity forecasts video engagement in an internet attention market

The growth of the internet has spawned new “attention markets,” in which people devote increasing amounts of time to consuming online content, but the neurobehavioral mechanisms that drive engagement in these markets have yet to be elucidated. We used functional MRI (FMRI) to examine whether individuals’ neural responses to videos could predict their choices to start and stop watching videos as well as whether group brain activity could forecast aggregate video view frequency and duration out of sample on the internet (i.e., on youtube.com). Brain activity during video onset predicted individual choice in several regions (i.e., increased activity in the nucleus accumbens [NAcc] and medial prefrontal cortex [MPFC] as well as decreased activity in the anterior insula [AIns]). Group activity during video onset in only a subset of these regions, however, forecasted both aggregate view frequency and duration (i.e., increased NAcc and decreased AIns)—and did so above and beyond conventional measures. These findings extend neuroforecasting theory and tools by revealing that activity in brain regions implicated in anticipatory affect at the onset of video

Análise do impacto da implantação de sistemas ERP nas características organizacionais das empresas de construção civil

Uma das causas do insucesso do ERP nas empresas de construção civil é o fato da implantação desse sistema ser uma grande mudança organizacional. O objetivo desta pesquisa é identificar como a implementação do sistema ERP impacta na organização e nos processos gerencias das empresas de construção civil. Foi realizada uma survey em uma amostra de empresas construtoras brasileiras. Os dados foram coletados por meio de um questionário encaminhado por email a dois grupos de empresas: com e sem ERP implantado. A partir da análise estatística discriminante foi possível identificar as variáveis relacionadas ao nível de desenvolvimento dos processos de gestão e as características organizacionais que mais distinguem os dois grupos de empresas. Os resultados revelaram que a implantação do ERP impacta nas variáveis da maturidade organizacional nos seguintes aspectos: visão estratégica, relacionamento com cliente, gerenciamento de recursos humanos, gestão financeira e de TI

Snakebite during pregnancy

PubMedID: 16119247Little is known about snakebites during pregnancy and only a few cases have been reported in the literature. The fact that venomous snakebites during pregnancy result in high fetal wastage and may cause maternal mortality makes this an important, albeit, uncommonly encountered entity in emergency medicine. In this paper, we report on the successful treatment of three cases of snakebite in pregnancy. © 2005 Edward Arnold (Publishers) Ltd

Unusual electrocardiographic changes with propranolol and diltiazem overdosage: a case report.

PubMedID: 12845395The therapeutic efficacy and safety of beta-adrenoreceptor-blocking drugs has been well established in patients with angina pectoris, cardiac arrhythmias, and hypertension and reducing the risk of mortality and nonfatal reinfarction on survival of acute myocardial infarction. The calcium antagonists are used for the treatment of patients with angina pectoris, long-term systemic hypertension, and the management of hypertensive emergencies and also for a multitude of other cardiovascular and noncardiovascular conditions. Because adverse cardiovascular effects can occur, however, patients being considered for combination treatment with propranolol and diltiazem must be selected carefully and observed closely. In this article, we present a suicidal case of drug overdose with propranolol and diltiazem with unusual electrocardiographic changes

Parotitis due to organophosphate intoxication

PubMedID: 12215051Acute pancreatitis due to pancreatic exocrine over-secretion induced by organophosphate poisoning has been previously reported but parotid gland involvement has not. This paper describes a case of acute organophosphate-induced parotitis in a patient with pre-existing sialolithiasis. The patient developed bilateral facial swelling in the pre-auricular area extending to the angle of the jaw and also developed elevated serum amylase on the second day of the poisoning. Serum lipase remained normal. Autopsy confirmed parotid gland inflammation and pre-existing ductal lithiasis. This case illustrates that organophosphate-induced parotitis can occur and should be considered in patients with organophosphate poisoning who have hyperamylasemia without elevation in serum lipase

High-dose verapamil + trandolapril-induced thrombotic microangiopathy

PubMedID: 12611489Thrombotic microangiopathy (TMA) is a syndrome characterized by microangiopathic haemolytic anaemia, thrombocytopenia, and several variable signs of organ damage due to the platelet thrombi in the microcirculation. This article reports a case with TMA which developed after ingestion of a high-dose combination of verapamil and trandolapril. To the authors' knowledge, no prior cases of TMA induced by trandolapril (an angiotensin-converting enzyme inhibitor) and verapamil (a calcium channel blocker) have been reported in the literature

Add oleander to your list of corrosives

Introduction: Nerium oleander is a toxic ornamental plant which usually grows in the Mediterranean area. In the past it was used to produce cardiotonic medicine and there are studies on using this plant as an anti-cancer medicine and on its use in alternative medicine for many causes. Case Presentation: Our case was of a 36 years old male who came to the emergency department with sore throat and burning feel in the throat following his curious bite of the oleander leaf. He had no trouble of breathing. The physical examination of the mouth showed burn-like lesions and edema of the uvula, oropharyngeal hyperemia, congestion and on the second day; necrosis. The edema and necrosis were later reduced with the treatment. We discharged the patient after observing for three following days without any complications or side effects. Conclusion: Besides the systemic effects of the oleander plant, this case demonstrates that it could cause serious tissue necrosis when applied locally and corrosive esophagitis when taken by oral way. Patients must be examined and followed also for local toxic effects. © 2019 Emergency Medicine Association of Turke

Levofloxacin-induced hepatotoxicity and death

PubMedID: 24067876Drug-induced hepatotoxicity is a major cause of hepatocellular injury in patients admitting to emergency services with acute liver failure. Hepatic necrosis may be at varying degrees from mild elevations in transaminases to fulminant hepatitis, and even death. The case of a 53-year-old female patient with toxic hepatitis due to levofloxacin and multiple organ failure secondary to toxic hepatitis is presented. Patient suffered itching, redness, and rash after receiving a single dose of 750 mg of levofloxacin tablets for pulmonary infection 10 days ago. Skin lesions had regressed within 3 days, but desquamation formed all over the body. After the fifth day of drug intake, complaints of abdominal pain, vomiting, and yellowing in skin color had started. The patient was referred to our emergency department with these complaints 10 days after drug intake. Patient was thought as a candidate for liver transplant, but cardiopulmonary arrest occurred, and the patient died before she could be referred to a transplant center. This case is important because hepatotoxicity and death due to levofloxacin is uncommon in the literature. Copyright © 2013 Wolters Kluwer Health, Inc. All rights reserved
