Measurement of enzymes concentration of mostly the latter type in plasma gives valuable informatio0n about disease involving tissues of their origin discount dutasteride 0.5mg free shipping. The plasma lipase level may be low in liver disease dutasteride 0.5mg online, Vitamin A deficiency order dutasteride 0.5mg free shipping, some malignancies, and diabetes mellitus. It is present in pancreatic juice and saliva as well as in liver fallopian tubes and muscles. The plasma amylase level may be low in liver disease and increased in high intestinal obstruction, mumps, acute pancreatitis and diabetes. They are found in bone, liver, kidney, intestinal wall, lactating mammary gland and placenta. In bone the enzyme is found in osteoblasts and is probably 20 important for normal bone function. Serum alkaline phosphatase levels may be increase in congestive heart failure result of injury to the liver. It is present in high concentration in liver and to a lesser extent in skeletal muscle, kidney and heart. It is widely distributed with high concentrations in the heart, skeletal muscle, liver, kidney, brain and erythrocytes. The enzyme is increased in plasma in myocardial infarction, acute leukemias, generalized carcinomatosis and in acute hepatitis. Estimation of it isoenzymes is more useful in clinical diagnosis to differentiate hepatic disease and myocardial infarction. Measurement of serum creatine phosphokinase activity is of value in the diagnosis of disorders affecting skeletal and cardiac muscle. Carbohydrates in general are polyhydroxy aldehydes or ketones or compounds which give these substances on hydrolysis. Chemistry of Carbohydrates Classification and Structure Classification There are three major classes of carbohydrates • Monosaccharides (Greek, mono = one) • Oligosaccharides (Greek, oligo= few) 2-10 monosaccharide units. The most abundant monosaccharides in nature are the 6-carbon sugars like D- glucose and fructose. One of the carbon atoms is double bonded to an oxygen atom to form carbonyl group. Structure of Glucose Open chain D-glucose α-D –glucose α-D –glucose (Fisher formula) (Haworth formula) Fig. Monosaccharides having aldehyde groups are called Aldoses and monosaccharides with Ketone group are Ketoses. Depending on the number of carbon atoms, the monosaccharides are named trioses (C3), tetroses (C4), pentoses (C5), hexoses (C6), heptoses (C7). No of carbon atoms Generic name Aldose family Ketose family 3 Triose Aldotriose Ketotriose Eg. Asymmetric Center and Stereoisomerism Asymmetric carbon is a carbon that has four different groups or atoms attached to it and having optically activity in solution. All the monosaccharides except dihydroxyacetone contain one or more asymmetric or chiral carbon atoms and thus occur in optically active isomeric forms. Monosaccharides with n number n of asymmetric centers will have (2 ) isomeric forms. The designation of a sugar isomer as the D- form or of its mirror images the L- form is determined by the spatial relationship to the parent compound of the carbohydrate family. When a beam of plane- polarized light is passed through a solution of carbohydrate it will rotate the light either to right or to left. Depending on the rotation, molecules are called dextrorotatory (+) (d) or levorotatory (-) (l). When equal amounts of D 25 and L isomers are present, the resulting mixture has no optical activity, since the activities of each isomer cancel one another. Epimers When sugars are different from one another, only in configuration with regard to a single carbon atom (around one carbon atom) they are called epimers of each other. The resulting six membered ring is called pyranose because of its similarity to organic molecule Pyran. This five membered ring is called furanose because of its similarity to organic molecule furan Fig 2. Glycosidic bond is formed when the hydroxyl group on one of the sugars reacts with the anomeric carbon on the second sugar. Maltose is hydrolyzed to two molecules of D- glucose by the intestinal enzyme maltase, which is specific for the α- (1, 4) glycosidic bond. Structure of Maltose Lactose Lactose is a disaccharide of β-D galactose and β-D- glucose which are linked by β-(1,4) glycosidic linkage. Lactose acts as a reducing substance since it has a free carbonyl group on the glucose. Since the anomeric carbons of both its component monosaccharide units are linked to each other. Structure of sucrose α-(1, 2) β-Glycosidic bond Polysaccharides Most of the carbohydrates found in nature occur in the form of high molecular polymers called polysaccharides. These are: • Homopolysaccharides that contain only one type of monosaccharide building blocks. Homopolysaccharides Example of Homopolysaccharides: Starch, glycogen, Cellulose and dextrins. It is especially abundant in tubers, such as potatoes and in seeds such as cereals. Starch consists of two polymeric units made of glucose called Amylose and Amylopectin but they differ in molecular architecture. Amylose is unbranched with 250 to 300 D-Glucose units linked by α-(1, 4) linkages Amylopectin consists of long branched glucose residue (units) with higher molecular weight. The branch points repeat about every 20 to 30 (1-4) linkages Glycogen - Glycogen is the main storage polysaccharide of animal cells (Animal starch). Cellulose is a linear unbranched homopolysaccharide of 10,000 or more D- glucose units connected by β-(1, 4) glycosidic bonds. Humans cannot use cellulose because they lack of enzyme (cellulase) to hydrolyze the β-( 1-4) linkages. Figure: Structure of Cellulose 30 Dextrins These are highly branched homopolymers of glucose units with α-(1, 6), α-(1, 4) and α-(1, 3) linkages. Since they do not easily go out of vascular compartment they are used for intravenous infusion as plasma volume expander in the treatment of hypovolumic shock. Hetero polysaccharides These are polysaccharides containing more than one type of sugar residues 1. They have the special ability to bind large amounts of water, there by producing the gel-like matrix that forms the basis of the body’s ground substance. Since they are negatively charged, for example, in bone, glycosaminoglycans attract and ++ + + tightly bind cattions like ca , they also take-up Na and K 3. An example of specialized ground substance is the synovial fluid, which serves as a lubricant in joints, and tendon sheaths. Heparin: • contains a repeating unit of D-glucuronic and D-gluconsamine, with sulfate groups on some of the hydroxyl and aminx-groups • It is an important anticoagualtn, prevents the clotting of blood by inhiginting the conversion of prothrombin to throbin. Thrombin is an enzyme that acts on the conversion of plasma fibrinogen into the fibrin.
The capacity for health communication for communicable diseases would be significantly improved by enhanced collaborative working and greater coordination at a European level 0.5 mg dutasteride amex. A useful definition of partnership is that it is a mutually beneficial and well-defined relationship entered into by two or more organisations to achieve common goals  purchase 0.5 mg dutasteride fast delivery. Consultation with stakeholders identified a belief that no common understanding existed of what needs to be achieved to effectively develop health communication discount 0.5 mg dutasteride amex. Partnerships facilitate the optimal use of resources, including skills and experiences. Capacity-developing partnerships are those that increase the capacity of the partnership members to work together . Partnership relationships may comprise different levels of involvement and commitment ranging from networking, coordinating, and cooperating through to collaboration. This lack of clarity exists between countries, within countries, and across the different stakeholder groups. Such a strategy is required to enhance collaborative working and strengthen partnerships and professional networks among those working in the area of health communication and communicable diseases within countries and across all Member States. Sustainable communication with organisations involved in health communication for non-communicable diseases could facilitate establishing networks to explore the transferability of expertise, capacity, information, best practice and lessons learned in health communication for non- communicable diseases to communicable diseases. However, the consultations identified that a degree of partnership working is already taking place. Participants reported that, at national level in some countries, health communication experts meet annually via meetings and conferences to discuss public health issues. Professional networks were seen as crucial for the successful managing of crisis situations. This campaign and similar may serve as a template for further collaborative initiatives. Participants highlighted that ‘sharing’ for health communication in the prevention and control of communicable diseases could potentially limit costs, facilitate transnational approaches and ensure a commonality of health communication messages and strategies across Europe [1-3]. Sharing of experiences and knowledge between countries can contribute to the development of capacity for such activities in a relatively cost-effective manner. There are many challenges to the establishment and maintenance of productive cross country partnerships for health communication for the prevention and control of communicable diseases in Europe, including the diversity of culture, health service systems and language. The non-communicable disease sector was said to partner with high profile individuals to ‘champion’ causes to an extent that the communicable disease sector does not. High profile individuals equipped with, and willing to deliver, key messages are valuable and unique resources and health communicators in the field of communicable diseases could usefully cultivate such advocates. The review of social marketing for the prevention and control of communicable diseases cited data that identified a promising trend in partnership working. The reviewers identified the recommendation that better reporting on partnership development is needed in order to enhance understanding as to how partnerships work and what outcomes are associated with such partnerships . Partnership building would benefit from the inclusion of the general public and community groups to incorporate the perspective of key target audiences for health communication activities. The importance of partnerships with community groups reflects the new paradigm of citizen-centred health communication. The importance of identifying stakeholders was noted earlier in relation to professional stakeholders however, the development of citizen-centred health communication demands, also, the identification of citizen stakeholders as active partners. An initial step towards the creation and maintenance of formal partnerships would be the creation of an up-to-date directory of key people working within the areas of health communication and health protection in Member States in order to facilitate networking. A platform that would facilitate both face-to-face and electronic engagement opportunities to share, discuss and reflect on health communication information and approaches would also be an important resource. The willingness of stakeholders to engage in the online consultation component of this project indicates a significant potential for the development of a vibrant virtual community of practice. A strong, linked professional network of communicators and experts within countries and across Europe will provide a useful resource to drive the strategic and consistent development of health communication for communicable diseases. Financial resources The generation and allocation of financial resources necessary to carry out health communication activities. The stakeholder consultation identified that no country has a specific budget for health communication . Funding for health communication is allocated from national health budgets and/or government programmes. Governments may fund directly or indirectly through national institutions and/or specific disease programmes. The lack of specific budgets was perceived by the stakeholders as evidence of the low profile of health communication in the prevention and control of communicable diseases. The extent to which stakeholders reported funding from the private and commercial sectors varied between countries. Whereas some participants reported that these sectors financed some or many health communication activities, others indicated that their country had regulatory controls which made it difficult for these sectors to provide finance. The most commonly reported involvement of pharmaceutical companies was in relation to vaccinations and, more specifically, in relation to promotional events and activities . Some stakeholders expressed concern that the current era of austerity may present a challenge even to the sustainability of ongoing projects and activities. However, the challenge of an economic crisis was also characterised by some as an opportunity to develop stronger partnerships and collaborations to make more effective use of available funding. Thus while stakeholders were clear about the importance of the availability of adequate financial resources, it was not necessarily considered to be the top priority. Once again, facilitated sharing of resources such as core materials and knowledge and the use of initiatives such as the European Immunisation Week were seen as an effective and efficient use of scarce financial resources. Greater use of the opportunities offered by technological advances was also suggested as a cost efficient use of limited resources. Stakeholders reported that many health communication messages are still disseminated in the form of printed materials  and recommended investment in cheaper online and social media channels. However, care must be taken to avoid widening health inequalities through an unevaluated move towards electronic channels as this could exclude populations already disadvantaged by low literacy levels, socio-economic status, or transient lifestyle . As has been noted, evaluation of health communication is particularly underdeveloped, and lack of financial resources was cited as one of the reasons for this . The evidence review of health advocacy  highlighted the historic lack of evaluation in that field as being replaced by a new expectation from funders that interventions and activities will be subject to systematic evaluation often at the formative, process and impact/outcome level. Consultation with the stakeholders identify that the way forward for the best use of resources for health communication lies in ring-fenced budgets but also in a more coordinated approach to spending and a sharing of resources across agencies and countries. Leadership and governance The ability and willingness of governments to critically analyse their work and accordingly search out opportunities to improve health communication by developing and implementing effective campaigns and initiatives and by expressing qualities in leadership and strategic thinking. The consultations identified that there was a lack of clarity about where responsibility for health communication rested both nationally and at a European level. With respect to risk communication, this perceived lack of clarity was seen to result in a deficit of strategic planning for health communication for communicable diseases and a focus on reactive crisis communication rather than planned health communication . Stakeholders recommended that in order to maximise its impact, health communication should become an integral part of national policies and strategies. To the extent to which health communication was perceived to be on the agenda of national and pan-European organisations, funders and policymakers, it was predominantly with reference to non-communicable diseases and stakeholders considered that efforts should be made to increase the priority status of health communication for communicable diseases.

Note: The absence of an entry in columns a–d denotes either a value of less than 1,000 deaths or that no estimate was allocated to that entry. For columns f–k, a blank cell indicates that fewer than 1,000 deaths are attributable to the speciﬁc cause.

Chapter 3 provides an estimate for tetanus deaths ages zero to four of only 187,000. Hepatitis, tropical-cluster diseases, leprosy, dengue, Japanese encephalitis, trachoma, intestinal nematode infections, and other infectious diseases. Deaths for respiratory infections in the neonatal age group are those estimated by Lawn, Cousens, and Wilczynska (forthcoming) for their category sepsis or pneumonia. Low-birthweight deaths are those resulting from intrauterine growth retardation or preterm birth. Almost all low-birthweight deaths in the neonatal period result from preterm birth. Chapter 3 of this volume provides an estimate for birth asphyxia and birth trauma deaths ages zero to four of only 739,000 globally, of which 734,000 were estimated to occur under age one. Epilepsy, alcohol use disorders, Alzheimer’s disease and other dementias, Parkinson’s disease, multiple sclerosis, drug use disorders, post-traumatic stress disorder, obsessive-compulsive disorder, panic disorder, insomnia (primary), migraine, mental retardation attributable to lead exposure, and other neuropsychiatric disorders. Rheumatic heart disease, hypertensive heart disease, inﬂammatory heart diseases, and other cardiovascular diseases.

This table does not attempt to partition by age the very small number of deaths from respiratory infections under age 5. Low-birthweight deaths are those resulting from intrauterine growth retardation or preterm birth. Almost all low-birthweight deaths in the neonatal period result from preterm birth. The World Health Report 2005 cites that 45 percent (19,000) of the 4 million global neonatal deaths occur due to pre-term birth. Chapter 3 of this volume provides an estimate for low birthweight deaths ages zero to four of only 10,000, of which 10,000 were estimated to occur under age one.
