Owing to the problems with malnutrition in Crohn disease, a lactose-restricted diet should not be recommended unless there is clear-cut improvement in diarrhea with lactose restriction. Cholestyramine is the classic example of an agent that interferes with nutrient (especially cations such as zinc) and drug absorption. Dietary Therapy in Liver Disease Two important manifestations of chronic liver disease, ascites and portosystemic encephalopathy, have dietary modification as a cornerstone of treatment. Severe dietary sodium restrictions are no longer recommended since such restrictions will likely promote malnutrition. Patients with advanced liver disease, including cirrhosis, have a high prevalence of protein- calorie malnutrition which adversely affects the underlying liver disease and results in poor clinical outcome. Restricting protein intake in patients with portosystemic encephalopathy has not been shown to be beneficial in several randomized trials and is therefore not generally recommended. Vegetable protein may be less ammoniagenic that meat, postulated to be due to a number of factors. Factors cited include a vegetarian diet increased dietary fiber in the vegetarian diet leading to increased elimination of nitrogen in the gut and increased levels of plasma arginine and citrulline leading to increased ammonia removal via the Krebs-Henseleit cycle. If confirmatory tests are not available and if there are strong clinical grounds for suspecting a deficiency state, appropriate replacement therapy should be initiated. Table 7 lists a number of hereditary liver diseases for which appropriate therapy includes specific dietary interventions.

Introduction The decision to intervene nutritionally is based on a number of disparate factors, including the current nutritional status of the patient (well-nourished versus malnourished), the duration of the time the patient will be expected to be unable to eat, the underlying medical condition and the prognosis for recovery. Once the decision to intervene has been made, the next decision is the method of intervention: oral, enteral or parenteral. It is thus important to detect malnourished patients and improve their nutritional status by providing nutritional support. There are several methods to assess nutritional status; the best method would be the one that predicts clinical outcome. In particular, the best method would predict nutrition-associated complications that increase the risk of morbidity and mortality in the absence of nutritional intervention. However, since it is often difficult to dissect out the effects of malnutrition from the effects of disease, nutritional assessment cannot rely on a single parameter or simple model. Furthermore, disease can affect several parameters used for nutritional assessment independently of nutritional status. Body composition Several methods can be used to measure various body compartments and most are used within a research protocol. The ones most frequently used clinically are based on a two compartment model: body fat and lean body mass (muscle, bones). This method is mostly used in population studies and is less reliable in the individual patient because of inter- and intra-observer variability and the effect of hydration status, age and physical activity. Studies have shown that unintentional weight loss of > 10% is a good predictor of adverse clinical outcome. Normalized for height, the 24-hour creatinine excretion is an index of muscle mass and can be compared to published tables. However, in a hospital environment, this is not used because of frequent underlying renal disease and use of diuretics. Plasma proteins Albumin is one of the most studied proteins and several studies have demonstrated that low serum albumin concentration correlates with an increased incidence of medical complications 1 and mortality. Therefore, hospitalized patients may have lower albumin levels for several reasons: inflammatory disorders First Principles of Gastroenterology and Hepatology A. On the other hand, protein-calorie malnutrition causes a decrease in the rate of albumin synthesis, but a short-term reduction in albumin synthesis will have little impact because of albumins low turnover rate (half-life: 20 days) and large pool size. Even during chronic malnutrition, plasma albumin concentration is often maintained because of compensatory decrease in albumin degradation and transfer of extravascular albumin to the intravascular compartment. Another plasma protein, prealbumin, is more responsive to nutritional changes because its turnover rate is rapid with a half-life of 23 days. However, it is also influenced by underlying diseases such as inflammation, infections, renal and liver failure. Immune competence As measured by delayed cutaneous hypersensitivity is affected by severe malnutrition. However, other diseases and drugs may also influence the measurements making it a poor predictor of malnutrition in sick patients. A prognostic nutritional index depending largely on albumin and transferrin was shown to provide a quantitative estimate of postoperative complication (Blackburn, 1977). It categorizes the patients as being well nourished (A) or as having moderate or suspected malnutrition (B) or severe malnutrition (C) (Table 10). It is important to recognize the multiple facets of malnutrition to detect the patient at risk of nutrition-related complications.

This raises the downside risks arising from antimicrobial serious concerns in the public health arena over resistance. Antibiotic usage in animal agriculture is complex as antibiotics are used not only for There are major data and information gaps on therapeutic purposes, but also for the prevention the use of antibiotics in agricultural production of infectious diseases and to promote animal and on the development and spread of resistance.

The answer is that Kelvin knew about the importance of you cannot improve it measurement. Measurement frstly to set the baseline and then repeated measurement to check if things are something and express improving. When measurement is being planned consideration needs to be given to the specifc But when you cannot reason for collecting data as this will inform the type and quality of data to be collected. The use of structure, process and outcome measures will be considered in more detail in chapter 11. A metric is a quantifable measure antimicrobials supplied to wards and other clinical areas. These doses recommended for clinical use because the doses for data will give an indication of the number of times antibiotics individual patients will be based on patient characteristics, such were used. In the community setting the simplest denominator is the number of inhabitants in the population. Normalising antibiotic use and presenting it as a rate will help account for fuctuations in hospital activity such as the number of patients in hospital When comparing antibiotic use between hospitals also and their length of stay. This requires information on bed hospitals with specialist units such as intensive care units utilisation. The landmark guidance on antimicrobial stewardship may have higher use of antibiotics than a local non-specialised hospital. The key disadvantage of the quantitative approach is whether it Are they prescribed in line with local guidelines? Remembering against antimicrobial resistance and assess the efectiveness of the principle that we need to measure to improve, then, the use interventions through repeated surveys.

Vaginistic women vary widely in their sexual behavior repertoire: from very limited to very extensive. In some cases, the desire to have children is rst and foremost, without there being any real motivation to work on the sexual relationship. Prevalence rates for vaginismus are scant, without the benet of multiple studies on specic populations. There are various theories on the causes of vaginismus, each with its own therapeutic approach. Research has demonstrated persist- ent problems with the sensitivity and specicity of the differential diagnosis of these two phenomena. All these three phenomena are typical of vaginismus, but may also be present in dyspareunia. Vaginismus 275 women from matched controls on the basis of muscle tone or strength differences (3,9,10). Finally, there is accumulating basic research to support the idea that the pelvic oor musculature, like other muscle groups, is indirectly innervated by the limbic system and there- fore highly reactive to emotional stimuli and states (1416). On the basis of this emerging knowledge of the underlying pathophysiologic mechanisms, it is obvious that current diagnostic categories of vaginismus and dyspareunia may overlap, and need to be reconceptualized. The same goes for the spasm-based denition of vaginismus despite the absence of research conrming this spasm criterion. At the 2nd International Consultation on Erectile and Sexual Dysfunctions in July 2003 in Paris, a multidisciplinary group of experts in the eld has proposed new denitions of vaginismus and dyspareunia (2,17). Vaginismus is dened as: The persistent or recurrent difculties of the woman to allow vaginal entry of a penis, a nger, and/or any object, despite the womans expressed wish to do so. Dyspareunia is dened as: Persistent or recurrent pain with attempted or complete vaginal entry and/or penile vaginal intercourse. The authors clarify that the experience of women who cannot tolerate full penile entry and the movements of intercourse because of pain needs to be included in the denition of dyspareunia. Clearly, they state, it depends on the womans pain tolerance and her partners hesitance or insistence. A decision to desist the attempt at full entry of the penis or its movement, within the vagina, should not change the diagnosis. Finally, they recommend that the diagnoses be accompanied by descriptors relating to associated contextual factors and to the degree of distress. There are various theories on the causes of vaginismus and each has its own therapeutic approach. In other words, a psychological complaint (anxiety) is changed into a phys- ical symptom (a vaginistic reaction). According to Musaph, why some women are vaginistic whereas other are not depends on whether they have a primary disposition towards suppression as a defense mechanism; this might be towards a disrupted motherchild relationship, or other stressful situations that occurred in the oral and oedipal phase of emotional development. Although psychoanalysis has paid a great deal of attention to the develop- ment of sexuality, very few analysts have written about treatment for vaginismus. Musaph distinguished between two forms of psychoanalytical therapy: dynamic- oriented therapy and classical psychoanalysis.
