Hälsorisker med kosttillskott i e-handel / Health risks with dietary supplements online

Vänman, Hanna January 2023 (has links)
The usage of dietary supplements has increased in the last decades and it’s getting more common to sell them online on websites in Sweden. Information about dietary supplements is not allowed to be misleading. Companies that sell them are for example not allowed to say that their products alleviate diseases. This study aimed to find out the health risks with dietary supplements online and see how often medical claims are stated on websites. The method used was controlling websites that sell dietary supplements to find medical claims. Also analyzing reports from a Swedish municipalities control done on companies that sell dietary supplements online. The results showed that medical claims appeared on 73% of the controlled websites. It was not possible to ensure any differences for the study’s selected categories on the websites. It was clear according to the study that consumers can be misled with misleading claims or lacking information, which can lead to health risks. Incorrect information can lead to children ingesting dietary supplements and having allergic reactions, as well as overdosing on dietary supplements, which can lead to liver damage. Medical claims can vary in severity but claims that say to reduce various diseases are considered risky as dietary supplements can be taken instead of medicine. This can make an illness or inflammation worse and cause unnecessary suffering. The result showed that buying dietary supplements online does not lead to such great health risks in general.

A system dynamics simulation model for environmental risk assessment at strategic level in power plants

Al Mashaqbeh, S.M., Munive-Hernandez, J. Eduardo, Khan, M. Khurshid, Al Khazaleh, A. 25 November 2020 (has links)
Yes / In a constantly changing business environment, a systematic approach is needed for risk assessment in order to allow for a more long-term strategic view. The System Dynamics (SD) modelling technique can be applied as an effective approach to understand the dynamic behaviour of a system over time. This understanding can be subsequently explicitly reflected on policies, strategic plans and operational procedures. This paper presents a SD model to assess environmental risks in power plants. The model helps to understand the long-term behaviour of the system under study. A questionnaire and focus group interviews have been conducted to understand the relationship among various risks. The SD model has been validated with two power plants in the Middle East. The developed model highlighted the impact of environmental risks on the performance of power plants. Although the SD model focuses on risk assessment in power plants, it can be easily adapted to other industry sectors.

Medication-related risk factors and its association with repeated hospital admissions in frail elderly: A case control study

Cheong, V-Lin, Sowter, Julie, Scally, Andy J., Hamilton, N., Ali, A., Silcock, Jonathan 14 February 2019 (has links)
Yes / Repeated hospital admissions are prevalent in older people. The role of medication in repeated hospital admissions has not been widely studied. The hypothesis that medication-related risk factors for initial hospital admissions were also associated with repeated hospital admissions was generated. To examine the association between medication-related risk factors and repeated hospital admissions in older people living with frailty. A retrospective case-control study was carried out with 200 patients aged ≥75 years with unplanned medical admissions into a large teaching hospital in England between January and December 2015. Demographic, clinical, and medication-related data were obtained from review of discharge summaries. Statistical comparisons were made between patients with 3 or more hospital admissions during the study period (cases) and those with 2 or fewer admissions (controls). Regressions were performed to establish independent predictors of repeated hospital admissions. Participants had a mean age of 83.8 years (SD 5.68) and 65.5% were female. There were 561 admission episodes across the sample, with the main reasons for admissions recorded as respiratory problems (25%) and falls (17%). Univariate logistic regression revealed five medication-related risks to be associated with repeated hospital admissions: Hyper-polypharmacy (defined as taking ≥10 medications) (OR 2.50, p < 0.005); prescription of potentially inappropriate medications (PIMs) (OR 1.89; p < 0.05); prescription of a diuretic (OR 1.87; p < 0.05); number of high risk medication (OR 1.29; p < 0.05) and the number of 'when required' medication (OR 1.20; p < 0.05). However, the effects of these risk factors became insignificant when comorbid disease was adjusted for in a multivariable model. Medication-related risk factors may play an important role in future repeated admission risk prediction models. The modifiable nature of medication-related risks factors highlights a real opportunity to improve health outcomes.

Talking about falls: a qualitative exploration of spoken communication of patients' fall risks in hospitals and implications for multifactorial approaches to fall prevention.

McVey, Lynn, Alvarado, Natasha, Healey, F., Montague, Jane, Todd, C., Zaman, Hadar, Dowding, D., Lynch, A., Issa, B., Randell, Rebecca 15 November 2023 (has links)
Yes / Inpatient falls are the most common safety incident reported by hospitals worldwide. Traditionally, responses have been guided by categorising patients' levels of fall risk, but multifactorial approaches are now recommended. These target individual, modifiable fall risk factors, requiring clear communication between multidisciplinary team members. Spoken communication is an important channel, but little is known about its form in this context. We aim to address this by exploring spoken communication between hospital staff about fall prevention and how this supports multifactorial fall prevention practice. Data were collected through semistructured qualitative interviews with 50 staff and ethnographic observations of fall prevention practices (251.25 hours) on orthopaedic and older person wards in four English hospitals. Findings were analysed using a framework approach. We observed staff engaging in 'multifactorial talk' to address patients' modifiable risk factors, especially during multidisciplinary meetings which were patient focused rather than risk type focused. Such communication coexisted with 'categorisation talk', which focused on patients' levels of fall risk and allocating nursing supervision to 'high risk' patients. Staff negotiated tensions between these different approaches through frequent 'hybrid talk', where, as well as categorising risks, they also discussed how to modify them. To support hospitals in implementing multifactorial, multidisciplinary fall prevention, we recommend: (1) focusing on patients' individual risk factors and actions to address them (a 'why?' rather than a 'who' approach); (2) where not possible to avoid 'high risk' categorisations, employing 'hybrid' communication which emphasises actions to modify individual risk factors, as well as risk level; (3) challenging assumptions about generic interventions to identify what individual patients need; and (4) timing meetings to enable staff from different disciplines to participate. / This research was funded by the National Institute for Health and Care Research Health Services and Delivery Research Programme (project number HSDR NIHR129488).

An investigation to determine incremental risks to software as a service from a user’s perspective

Ipland, Frederick Ferdinand 12 1900 (has links)
Thesis (MComm)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Software as a Service (SaaS) – which is a deployment model of cloud computing – is a developing trend in technology that brings with it new potential opportunities and consequently potential risk to enterprise. These incremental risks need to be identified in order to assist in risk management and therefore information technology (IT) governance. IT governance is a cornerstone of enterprise-wide corporate governance. For many entities corporate governance has become a statutory requirement, due to the implementation of legislation such as Sarbanes-Oxley Act of the United States of America. The research aims to assist in the IT governance of SaaS, by identifying risks and possible controls. By means of an in-depth literature review, the study identified 30 key risks relating to the use and implementation of SaaS from the user’s perspective. Different governance and risk frameworks were considered, including CobiT and The Risk IT Framework. In the extensive literature review, it was found that CobiT would be the most appropriate framework to use in this study. Mapping the risks and technologies from the user's perspective to one or more of the processes of the CobiT framework, the research found that not all processes where applicable. Merely 18 of 34 CobiT processes where applicable. The study endeavoured to identify possible controls and safeguards for the risks identified. By using the technologies and risks that were mapped to the CobiT processes, a control framework was developed which included 11 key controls to possibly reduce, mitigate or accept the risks identified. Controls are merely incidental if it is not linked to a framework. / AFRIKAANSE OPSOMMING: Software as a Service (SaaS) – ‘n ontplooiingsmodel van cloud computing – is ‘n ontwikkelende tegnologiese tendens wat verskeie moontlikhede, maar daarby ook verskeie risiko’s vir ondernemings inhou. Hierdie addisionele risiko’s moet geïdentifiseer word om te help met die bestuur van risiko’s en daarom ook die beheer van Informasie Tegnologie (IT). IT beheer is ‘n belangrike deel van die grondslag van ondernemingswye korporatiewe beheer. As gevolg van die implimentering van wetgewing soos die Sarbanes-Oxley wetsontwerp van die Verenigde State van Amerika, het korporatiewe beheer ‘n statutêre vereiste geword vir verskeie ondernemings. Hierdie studie poog om die IT beheer van SaaS by te staan, deur risiko’s en moontlike beheermaatreëls te identifiseer. Deur middel van ‘n indiepte literatuur ondersoek het die studie 30 sleutelrisiko’s geïdentifiseer wat verband hou met die gebruik en implimentering van SaaS vanuit ‘n gebruikersoogpunt. Verskeie korporatiewe- en risiko raamwerke, insluitende CobiT en The Risk IT Framework, was oorweeg. Die literatuur ondersoek het egter bevind dat CobiT die mees toepaslikste raamwerk vir dié studie sal wees. Deur die risiko’s en tegnologieë vanuit ‘n gebruikers perspektief te laat pas met een of meer CobiT prosesse, het die navorsing bevind dat nie alle prosesse in CobiT van toepassing is nie. Slegs 18 van die 34 prosesse was van toepassing. Die studie het ook gepoog om moontlike beheer- en voorsorgmaatreëls vir die risiko’s te identifiseer. Deur die tegnologieë en risiko’s te gebruik wat gepas is teen die CobiT prosesse, is ‘n beheer raamwerk ontwikkel wat 11 sleutel beheermaatreëls insluit, wat die geïdentifiseerde risiko’s kan verminder, temper of aanvaar. Beheermaatreëls is slegs bykomstig as dit nie direk aan ‘n raamwerk gekoppel is nie.

Framing Global Catastrophic Risk - Recent and Future Research

Ehringer, Wolfgang, Söderström, Henrik January 2017 (has links)
This article is a literature review about global catastrophic risks. Its contribution is to give an overview of the research field in general and highlight the main potential catastrophic areas linked with recent studies. In many movies and TV shows, we can see our civilization collapse in various ways: Gigantic asteroids hit the earth and obliterate all life, nuclear wars emerge, artificial intelligence evolves and starts wars with humans, pandemics spread, and other kinds of catastrophic events with mass death or extinction of all life happen. Thus, even if these are extreme events and fiction, we should raise the question how likely it is that one or more of these events can occur in the near and far future. Although calculated probabilities of impact are low for the future such as tomorrow, in 10, 100 or a million years from now, this could actually be reality. Nevertheless, why should we care about the risks of these global catastrophic events today and what could be done to prevent or reduce the risk of a global catastrophe? In this paper we will discuss core content, such as different risks and ways to reduce them internationally, as well as the scientific context of the field. In fact, there are events that can be catastrophic on a global scale and happen in the near future, even if we do not know exactly when. Hence, specific risk assessment and proper mitigation strategies are necessary in order to maintain the human population. This article states that serious research is a basis for decision makers in particular, who invest funds in countermeasures.

Apesar da utilização de novas tecnologias que visam a minimizar ou eliminar a ocorrência dos acidentes com tais produtos, houve aumento no número de acidentes com esses produtos, no período de 1980 – 2009, no estado de São Paulo. Um acidente com produto químico pode contaminar as águas e solos, devido ao vazamento de substâncias químicas, acarretando danos irreparáveis ao meio ambiente; além de ocasionar, por conseguinte, graves danos aos seres humanos, inclusive com óbitos. Conforme dados coletados, 72,2% do total dos acidentes com produtos químicos, ocorridos no estado de São Paulo, no período de 1980-2009, foram registrados nas atividades, relacionados aos riscos industriais e riscos tecnológicos. Nas atividades referentes aos riscos industriais: armazenamento, descarte, indústria, postos e sistemas retalhistas de combustíveis, ocorreram 22,6% do total de acidentes; nas atividades referentes aos riscos tecnológicos: transportes aquaviário, ferroviário, por duto e rodoviário, ocorreram 49,6% do total dos acidentes. Tais dados sobre os acidentes com produtos químicos só foram possíveis de serem devidamente analisados e interpretados porque foram espacializados. Nesse sentido, o uso do software Arc Gis foi importante para visualizar o total de acidentes, causas e meios atingidos no estado de São Paulo e, posteriormente, a distribuição espacial desses acidentes com produtos químicos por Região Administrativa, foi de grande valia para a compreensão dos acidentes pesquisados. A pesquisa revelou, também, que a legislação ambiental brasileira e paulista apresenta um histórico de atribuição de regulamentos referentes à preservação ambiental, relacionado ao desenvolvimento econômico desde a década de 1970. A tese a ser defendida, portanto, é a seguinte: apesar do emprego de novas tecnologias, da consciência ambiental e da legislação ambiental existente, muitos acidentes com produtos químicos têm ocorrido, ainda, no estado de São Paulo, demandando estudos sobre esses acidentes e a necessidade de fiscalização na aplicação das leis ambientais. / The purpose of this PhD thesis was to evaluate the occurrence of chemical accidents in the São Paulo state. Despite the use of new technologies aimed at minimizing or eliminating the occurrence of accidents with such products, there was an increase in the number of accidents with these products, from 1980 to 2009, in the São Paulo state. A chemical accident can contaminate water and soil due to the release of chemicals, causing irreparable damage to the environment; besides causing, consequently, serious damages to the human beings, even with deaths. According to data collected, 72.2% of the total number of chemical accidents occurred in the São Paulo state during the period 1980-2009 were recorded in activities related to industrial risks and technological risks. In activities related to industrial risks: storage, disposal, industry and gas stations, there were 22.6% of total accidents; in activities related to technological risks: waterway, rail, duct and road transportation, 49.6% of all accidents occurred. Such data on chemical accidents were only possible to be properly analyzed and interpreted because they were spatialized. In this sense, the use of the Arc Gis software was important to visualize the total number of accidents, causes and means reached in the São Paulo state and, later, the spatial distribution of these accidents with chemical products by Administrative Region, was of great value for the understanding of the accidents investigated. The research also revealed that Brazilian and São Paulo environmental legislation presents a history of the attribution of regulations regarding environmental preservation, related to economic development since the 1970s. The thesis to be defended, therefore, is the following: despite employment new technologies, environmental awareness and existing environmental legislation, many accidents with chemical products have also occurred in the São Paulo state, demanding studies on these accidents and the need for enforcement in the application of environmental laws.
