However generic malegra fxt plus 160 mg online erectile dysfunction hypothyroidism, some of your criteria will be set for practical reasons generic malegra fxt plus 160 mg with amex impotence is a horrifying thing, such as time and resources. Neither of these restrictions are ideal and you might lose relevant literature – there might be a piece of work which is highly relevant to your review but which was published before the date limitations you set. If you set time restrictions to your search for literature you would miss this key document, although it might be referred to in other papers. You should not limit a search to only access electronic full text availability, as even if you fnd it diffcult to physically visit your library, most libraries will offer a photocopying service. Again, in an ideal world, you would seek to access all available literature on your topic or research question. Non-aca- demic journals might also be referred to as grey literature and other informa- tion such as policies also falls into this category. Remember that exclusion criteria will reduce the number of results (hits) you get whereas inclusion criteria will increase them. These are: • Electronic searching using computer-held databases • Searching reference lists of articles you already have • Hand searching relevant journals specifc to the research topic or using elec- tronic journal searching • Contacting authors directly • Searching national guidelines/professional body sites. Computer held databases Searching for literature has become a far easier and effcient process with the advent of electronic databases for literature searching. If you have recently vis- ited your local academic or professional library, you will be very aware that the computer revolution has had a large impact on the ways in which we search for information. In the past (when we were students) those reviewing the lit- erature would have to search through hard-bound volumes of subject indexed references in which previously published literature was categorized under vari- ous keywords. They could not be immediately updated and updates took place often on a yearly basis. Those seeking information had no alternative other than to trawl through bound volumes to fnd information on a topic or by an author (and then commonly, anything published within the last year was unobtainable because it was in the process of binding). Nowadays, most of the information you need is accessible through one of many databases. In general there are two types of database often referred to in the literature searching process. These databases are compiled as follows: published papers are scrutinized and allocated keywords which are then indexed. Normally, the reference is given in the form of name, date of pub- lication, title of publication, title of journal in which the information is held and possibly an abstract for the paper. As an added bonus, some databases provide a link to an electronic copy of the full version of the paper. Electronic journal databases are useful when you know exactly what you are looking for and have a reference for a particular journal article. You can locate the journal you need and from that you can locate the particular article you need to get hold of. It is usually organized via an A–Z section which con- tains access to the electronic copy of the papers (journal articles). It is impor- tant to note that the electronic journal database does not allow you to search for what is written on your topic (the subject specifc database is better for this) but is useful to locate the sources identifed from the subject specifc databases. Getting started using databases Identify relevant databases to which you have access. Various health and social care databases will be available through professional websites, univer- sity or organizational libraries to which you belong. Different databases access literature from different countries or groups of countries or focus on specifc specialities or interest areas. Cochrane have a collection of databases in their ‘webliography’ available at http://www. Joanna Briggs Institute: systematic reviews, evidence summaries and best practice information sheets in nursing and allied health from the Joanna Briggs Institute. Web of Science: includes Science Citation Index and Social Sciences Citation Index. Covers about 20,000 current journals and conference proceedings in many key subject areas. This will reduce the number of hits you get as each term must be included in the article for it to be recognized. This will increase the number of hits you get as you only need to identify one of the terms for the article to be selected. There is also the ‘* facility’ which enables you to identify all possible end- ings of the key term you write. You need to identify the ‘root’ of the word for example, the part of the word that doesn’t change – and put the * after that last letter. For example: child* will identify articles containing child, children, children’s and so on. If you are a practice assessor/mentor, ask your student to show you how to search. Try and identify search terms for a question you have using this table (you can add rows or columns as you need to). You will fnd that you will develop new ideas as you undertake the searching pro- cess. You might fnd, for example, a key theme is called by a different name or phrase that you had not previously thought of. Once you have identifed the key literature on your topic using one data- base, you could repeat the search using another database. If you fnd that the same references are thrown up, then you can be confdent that your strategy is well focussed and that you are accessing the relevant literature on your topic. In this chapter we discuss database searching and your local library is likely to provide tutorials or help sheets in searching for evidence. When you get started you will fnd academic journals relating to a very wide range of professional interests. Some journals are generic to the interests of one professional group – for example Journal of Clinical Nursing or British Journal of Occupational Therapy, whilst others are specialist journals belonging to a particular area of profes- sional interest for example Addiction. Academic journals contain many articles about different topics related to the overall subject addressed by the journal. There are now an increasing number of specialist evidence-based practice journals such as: World Views on Evidence-based Nursing, Evidence-based Mental Health, Journal of Evidence-based Dental Health, Evidenced-based Complementary and Alternative Medicine, Journal of Evidence-based Social Work, Evidence-based Child Health, International Journal of Evidence-based Health Care, Evidence-based Midwifery. Journals often contain a mixture of research, literature reviews and discussion/ opinion articles, which we will discuss later on in this book in more depth. If new references are constantly being thrown up, you will need to continue searching until later searches reveal little or no new information. Despite the advances in electronic searching, computerized searching tools are not 100 per cent effective and will fail to identify some of the relevant literature on your topic. This is because: • Some relevant literature might have been categorized using different keywords and would therefore not be identifed by one particular search strategy. This means that the papers will not be recog- nized by the databases when you search for this topic. Authors who use imaginative titles for their work run the risk that their work will not be identifed by those who search on the topic. Although using vari- ous keywords will help identify literature that is not identifed on the frst search, it is still possible for literature to remain unidentifed even though it is highly relevant to addressing the research question.
Other causes include parasitic infection buy malegra fxt plus erectile dysfunction treatment pdf, drug hypersensitivity discount malegra fxt plus 160 mg visa erectile dysfunction drugs without side effects, and cellular rejection after cardiac transplantation, as well as postvaccinia myocarditis after smallpox vaccination. Although the histologic appearance of myocarditis occurring as part of sarcoidosis, systemic lupus erythematosus, or polymyositis is similar to that seen in isolated myocarditis, the natural history is different. Systemic causes of myocarditis often respond poorly to medical therapy and cardiac transplantation, and their prognoses are often unfavorable. However, small retrospective surveys and case series have identified a significant decrease in mortality and improved clinical course among cardiac sarcoid patients treated with corticosteroids and other immunosuppression strategies. On the basis of population studies, adults with myocarditis may present with few symptoms or with an acute toxic state of cardiogenic shock or frank heart failure (i. However, adults may present with heart failure years after the initial index event of myocarditis (up to 12. The outlook is poor in the acute phase, regardless of clinicopathologic classification, but those surviving the acute phase have a more favorable prognosis (except for those with chronic active myocarditis). Many patients may have full spontaneous clinical recovery, even after weeks of mechanical support (e. In the Myocarditis Treatment Trial, the 1-year mortality rate was 20%, and the 4-year mortality rate was 56%. In-hospital case series point to an 11-year survival rate of 93% for patients with fulminant myocarditis and 45% for nonfulminant myocarditis. Up to one-half of patients with myocarditis develop subsequent cardiomyopathy over a range of 3 months to 13 years. Severe heart block requiring permanent pacemaker placement occurs in 1% of patients. Favorable factors for survival include normal ventricular function, shorter clinical history, and fulminant presentation at onset. Standard heart failure therapy consists of diuretics, angiotensin-converting enzyme inhibitors, β-blockers, and aldosterone antagonists. Because of its proarrhythmic properties in animal models, digoxin should be avoided. Anticoagulation to prevent thromboembolic events is usually recommended in patients with apical aneurysm with thrombus (e. Inotropic therapy is reserved for severe hemodynamic compromise, particularly in fulminant myocarditis. Aggressive support with mechanical and surgical intervention is often indicated (see Chapters 8 and 12). Intra-aortic balloon counterpulsation for hemodynamic support and afterload reduction b. However, patients with myocarditis have increased rates of rejection and reduced survival after heart transplantation compared with those without myocarditis, and recurrent disease may affect the allograft. There is a theoretical increased risk of myocardial inflammation and necrosis, cardiac remodeling, and death, as shown in animal models. Patients are usually advised to abstain from vigorous exercise for up to 6 months or longer after the onset of symptoms. Antiarrhythmics provide first-line treatment using standard therapy such as β-blockers, amiodarone, and sotalol. Clinical follow-up should be close because persistent chronic inflammation may lead to dilated cardiomyopathy. Initially, 1- to 3-month intervals are used for drug and physical activity titration. Serial echocardiographic assessment of ventricular structure and function is often performed, although there is no agreement regarding the frequency of echocardiographic assessment after myocarditis. More work is needed to identify patient cohorts who will benefit from tailored antiviral and immunosuppressive therapy. Incidence of biopsy-proven myocarditis in recent-onset, unexplained heart failure can be as low as 8% to 10%. Concerns have emerged that this is caused by low sensitivity of the Dallas criteria, and several recent trials of immunosuppressive therapy have utilized supplemental pathologic criteria to assess myocarditis, including upregulation of human leukocyte antigen, presence of virus, and anticardiac antibodies. False-negative rates are high (50% even in four or five biopsies) because of the small number of lymphocytes and difficulties in distinguishing cell types, with wide interobserver variability. Rapidly progressive heart failure symptoms despite conventional therapy or new-onset frequent ventricular tachyarrhythmia or conduction disturbances b. Although specificity is high (98%), sensitivity has been found in some series to be as low as 10% to 22%. It increases with multiple biopsies, but postmortem examinations have found that more than 17 specimens were needed to make the diagnosis with 80% sensitivity in proven myocarditis cases.

Immunohistochemical staining to examine upregulation of major histocompatibility complex antigens and quantify inflammation, although rates of correlation with biopsy-proven myocarditis have not been consistent between studies. There is no Food and Drug Administration– approved regimen for the treatment of acute or chronic myocarditis. Considerations are reserved for patients with new-onset, rapidly deteriorating, advanced heart failure with suspicion of the following conditions: a. Studies are ongoing in an attempt to identify markers to predict favorable response to immunosuppressive regimens. Of those who failed conventional therapy, those patients who responded to immunosuppression were significantly more likely to have positive cardiac antibodies (90% vs. National Institutes of Health-sponsored workshop on inflammation and immunity in dilated cardiomyopathy.

Examples of decisions and the type of evidence they require decision 1: My patient/client has been diagnosed as an alcoholic and wants to self-discharge against the judgement of staff quality malegra fxt plus 160mg erectile dysfunction at age 29. Evidence you need to help you make a decision – you would need relevant legal and ethical principles regarding the right of the patient/client to discharge and the duty owed to him by the health or social care practitioner purchase malegra fxt plus mastercard hypothyroidism causes erectile dysfunction. You may also use professional judgement and prior experience in exploring with him the options for his care. You may also use your intuition and experience to help you respond to particular issues. You could fnd qualitative research that explores the mature student experience of placements. Evidence you need to help you make a decision – to answer any questions about the effectiveness of an intervention, you would need to fnd research, ideally in the form of systematic reviews or randomized controlled trials that have looked specifcally at the issue in question (we will discuss what randomized controlled trials are and why they are needed later on). Evidence you need to help you make a decision – you would need to explore the client’s rights as a father from a legal perspective, and the implications of his depression on his ability to care for his children which may come from qualitative research about the experiences of those with depression coping with parenthood. Evidence you need to help you make a decision – you would search to see if there is any research evidence, but in the absence of this you should examine up-to-date manufacturers’ instructions on their website http://www. Evidence you need to help you make a decision – you could search the literature on ‘pain assessment in cognitively impaired adults’. You may fnd validated assessment tools or advice on how best to assess this client group. You could discuss the behaviour with family/carers to see if it is indicative of pain. You could use other physiological measurements such as pulse and blood pres- sure recordings to assess the individual. You may fnd studies that report that pain is generally underassessed and treated in those with cognitive impair- ment. When you are looking for evidence on your topic, ‘one size’ really does not ft all. If any- one tells you that you ‘always need research evidence’ to answer your question, this would be misleading – you need the most relevant information that will answer your question. This is often research but as we have seen in the previ- ous examples, it might come from another source, for example policy, or legal or ethical principles. In a busy professional context, when you are manag- ing complex situations, you may fnd that there is no easy ft between the evidence and the environment you are working in. The type of evidence you need depends on the decision you have to make and you need to think care- fully about this to work out the type of evidence you need. When you seek out evidence to use in your practice, it is sometimes referred to as practising in an ‘evidence informed way’. The diffculty is that no one can tell you what type of evidence you need in a given situation; you need to use your own judgement to work this out. In order to do this, the frst thing you need to do is defne a question/refne the decision that identifes what you need to know. This is important because unless you are focussed, you will not be able to work out how to fnd the information and you will be swamped with information. Example: A friend asks about anti-malarial tablets as she is about to go off on a foreign adventure. If you do not identify exactly what your friend wants to know you will not be able to fnd the appropriate evidence to advise them in a meaningful way. You might fnd out which is the most effective whilst what they really wanted to know was which is the cheapest. The information you do fnd is likely to be of limited usefulness if it doesn’t fnd out what your friend wanted to know. If you are looking for evidence about the effectiveness of anti-malarial tab- lets, this evidence will not be the same as that you would look for if you were looking for evidence about the experiences of those who have used the differ- ent tablets. There are many decisions and many different kinds of evidence that will assist your decision making. What would be weak evidence for one decision would be stronger evidence for another decision. Different types of evidence were needed to assist with deci- sion making – legal rulings, policy and guidelines and research evidence. This is generally a weaker form of evidence for all types of decisions for the reasons outlined below. However if no other evidence is available you might consider that anecdotal evidence is the best available evidence to use. You try out a few choker collars which pull tighter around his neck when he pulls and relaxes when he walks nicely to heel. Here you have some evidence about which choker lead works best – at least for you and your dog. This is anecdotal evidence and is the type of evidence that people have gathered and used over the generations. Indeed a lot of health and social care has been based on anecdotal evidence in the absence of harder evidence being available. Now imagine that you have hundreds of dogs at a Guide Dog training centre and you need to know which lead works the best. In this instance, the anecdotal evidence gained from the experience of one person attempting to train his dog would not seem suffcient. This scenario can be transferred to health and social care settings in which the stakes are high. There are limited resources and patients/clients have an expectation and a right to receive the optimum care. We cannot afford to base practice on insubstantial evidence which does not stand up to scrutiny. In health and social care, anecdotal evidence can be: • Using something you’ve tried before that worked and you haven’t checked out whether there is an evidence base to support this. In principle, you should be aware that the quality of evidence provided by anecdotal information – even if it is based on expert opinion – is generally weaker than that which is provided by research or reviews of research. Remem- ber that if you do not ask for the evidence that lies behind the advice you are given, you might be practising using anecdotal evidence only and your prac- tice would not stand up to scrutiny. However, published material that does not report research fndings can still be useful. This is why it is important to determine what evidence you need in the frst instance. Anecdotal informa- tion can be useful in the following ways: • It can contribute to your professional judgement. With the availability of systematic and rigorous research studies, we now have more robust evidence upon which to base our practice. It is important that we use the right evidence for the question we want to answer. For the fow of argument in this book, we want to discuss some more general principles and ideas about research before we go into detail about the specifc studies themselves. However if any of the following examples do not make complete sense without additional information, do refer to Chapter 4.
