Symptoms (Psychotic/acute) Hallucinations See Chapter 5 ofloxacin 400 mg sale infection years after knee replacement. These items were kept by a young man with schizophrenia purchase 200mg ofloxacin otc antibiotic 500g. He was socially isolated and secretive and brought to hospital by his parents buy ofloxacin overnight delivery antibiotic resistant pneumonia. His parents explained that he had written “Cursing Jar For Good” on the lid of this jar, and had written multiple “curses” concerning “enemies” which he placed inside. His parents told that he behaved as if these curses were a serious matter, and he expected them to be effective. While not proof, this activity was highly suggestive of psychosis. The idea of a “cursing jar” appeared to have come from the fashion of maintaining a “cussing jar” in work-places and pubs, into which people were obligated to place money if they “cussed” (cursed/swore) – at intervals the contents to be donated to charity or similar “good” cause. The evidence suggested the patient believed he could cast spells or curses on other people (delusion). This was not appropriate in his culture and suggested a delusion. A well groomed young man (clothes in the background) was brought to hospital. When staff unpacked his belongings, they found a bag of human faeces. When he recovered, the patient explained he had believed his faeces contained gold dust, which he had intended to extract. The delusions described above are spectacular – the majority are far less so. Form of thought – Formal Thought Disorder (FTD) See Chapter 6. As mentioned above, derailment, incoherence and neologisms are ranked with the positive symptoms, while poverty of thought is ranked with the negative symptoms. Symptoms (Negative/chronic) The symptoms mentioned in DSM-5 will be discussed first. Accordingly, the mood disorders of current times [depression/mania] are still sometimes referred to as “affective” disorders, but this is not recommended. In examination of the mental state, the term affect refers to “the external manifestation of the internal feeling state”. It is said that affect is to mood as weather is to climate, introducing the notion of immediacy and brevity. In our interactions with others we expect some “emotional contact”, interest or personal warmth. We expect some animation, some facial, hand and body movements, some variation in tone of vice and speed of speech, or some sign of vigour or energy, during discussion of different topics. People with schizophrenia may have “blunted”, “flat” or “restricted” affect. Such patients tend to have relatively immobile face, limbs and trunk, with little change in speed of speaking or pitch of voice, irrespective of the topic of conversation. There appears to be reduced interest and personal warmth. It is assumed from these external manifestations that the internal feeling do not vary in the usual manner. This is a fair assumption, particularly in view of the fact that many people with flat affect also complain of lacking the ability to feel emotions. This occurs when an individual is thinking/talking on a subject, but displaying inappropriate feelings. For example, a patient talking of the death of a much loved relative may laugh uncontrollably. Anhedonia Anhedonia is the inability to experience pleasure. It is observed in various types of depressive disorder and schizophrenia.

Tis is the purpose of Research for universal health coverage. Tis report is for everyone concerned with understanding how to reach the goal of universal health coverage – those who fund the necessary research, those who do research and who would like to do research, and those who use the evidence from research. It shows how research for health in general underpins research for universal health coverage in particular. Understanding how to make progress towards achieving the MDGs is central to this report. As the 2015 deadline draws closer, we are looking for ways to improve all aspects of health, working within and beyond the MDG framework. And we are investigating how better health can contribute to the larger goal of human development. In this broad context, I invite you to read Research for universal health coverage.

Research has the power to address a wide range of questions about how we can reach universal coverage, providing answers to improve human health, well-being and development. The creativity and skills of researchers should be used to strengthen investigations not only in academic centres but also in public health programmes, close to the supply of and demand for health services. To make the best use of limited resources, systems are needed to develop national research agendas, to raise funds, to strengthen research capacity, and to make appropriate and effective use of research findings. In 2005, all WHO Member States made the commitment to achieve universal health coverage. Te commitment was a collective expression of the belief that all people should have access to the health services they need without risk of fnancial ruin or impoverishment. Working towards universal health coverage is a powerful mechanism for achieving better health and well-being, and for pro- moting human development. Chapter 1 explains how the resolution adopted by all WHO Member States embraces the two facets of universal health coverage: the provision of, and access to, high-quality health services; and fnancial risk protection for people who need to use these services. Te term includes ways of taking action on social and environmental determinants both within and beyond the health sector. Financial risk protection is part of the package of measures that provides overall social protection. Scientifc research has been fundamental to the improvement of human health. Research is vital in developing the technology, systems and services needed to achieve universal health coverage. On the road to universal coverage, taking a methodical approach to formulating and answering questions is not a luxury but a necessity. When WHO Member States made the pledge to achieve universal coverage they took a signifcant step forward for public health. As described in Chapter 1, taking that step efectively launched an agenda for research. In this report, research is the set of formal methods that turns promising ideas into practical solutions for improving health services, and consequently for improving health. Te goal of the report is to identify the research questions that open the way to universal health coverage and to discuss how these questions can be answered. Many recent advances have been made in health service coverage and in fnan- cial risk protection as shown, for example, by progress towards the United Nations Millennium Development Goals (MDGs). Despite this progress, the gap between the present coverage of health services and universal health coverage remains large for many conditions of ill-health in many settings.
