Personalised Cancer Care Question from Selma Schimmel: “How do we unify patient advocate efforts? We need to promote awareness and public understanding of this paradigm shift that cancer research is global in nature buy discount lansoprazole 15mg line gastritis head symptoms. So how do we take the global message forward discount lansoprazole 30mg amex gastritis diet , knowing that the internet allows patients all over the world to read common information purchase lansoprazole 30mg with amex gastritis diet zantrex, that research doesn’t happen in a vacuum and the tissue that’s collected in Hamburg may have an impact on a cancer centre in Rochester? For many years we have said that care should be patient-centric and clinical decisions should be tailored not only to patients’ genetic makeup but also their preferences buy 30 mg lansoprazole otc gastritis diet beverages, physical well-being and social circumstances. Personalised medicine – the development of drugs that are targeted to a specifc mutation – represents an important scientifc development but unfortunately there has been much Editor,Cancer Worldmagazine hype surrounding this advance which in reality has only had a limited impact on cancer patients. This hype is creating unrealistic expectations about what personalised medicine can deliver for the vast majority of patients today, and strong advocacy efforts are required to convey clear messages about which cancers are currently benefting from personalised medicine but also the potential of targeted therapies for cancer patients. A key part of this message is that mutation testing should be performed by laboratories with certifed competence to carry out the test, since accuracy and consistency of results are important. Unfortunately, mutation testing, when there is a drug to target the mutation, is still not widely available to European citizens today. In some countries patients face important barriers in accessing targeted drugs even when there is a clear indication based on mutation testing. Another message that needs to be communicated is that targeted drug therapy complements and enhances treatment with surgery and radiotherapy and that cancer treatment has to be planned by a multidisciplinary team working within the context of properly organised cancer services. The fnal message to communicate is that improvements in cancer outcomes will come only when patients receive the right treatment (be it surgery, drugs or radiotherapy) from the right people at the right time. The right people are competent health professionals who have both experience and specialist training in cancer. From the patient side, personalised medicine will bring better treatments, while at the same time creating a major shift in healthcare systems. The meaning of personalised medicine is totally obscure for the lay public, patients and often for politicians and policy makers. It is important to acknowledge that not in every place where cancer patients receive treatment is the best treatment available. This is the critical point for the patient so as to ensure that the patient is not over-treated or under-treated. From an economic perspective, with increased targeted treatments there will be a reduced risk of expensive treatments being used on patients who will not be responsive, so offering more value for healthcare and offering benefts to patients, society and healthcare systems in the long run. Changes will be necessary in the way medicines are developed, regulated and rewarded. Greater collaboration will be needed across a wide range of actors in healthcare, in particular with the patients. This was a key message that the cancer patient community has conveyed within the European Alliance for Personalised Medicine stakeholder initiative. In particular, in the area of research, we have called for: • More multidisciplinary research, with closer collaboration between drug and diagnostic developers, clinicians, biologists, biostatisticians and information and communications technologists. All in all, the regulatory environment must allow every patient access to personalised medicine. Research must be increased and fndings that will facilitate personalised medicine co-ordinated. In this context, new approaches to reimbursement are needed to ensure that new treatments can become accessible for patients. In terms of infrastructure, a European Institute should be created for translating the laboratory information into medicine. Additionally, continuous training of healthcare professionals is needed and this has to be done through the development of guidelines which must become a living document so as to respond to technological and scientifc changes that occur regularly. Of course, patients should be a central part of this dialogue for the development of these guidelines. Finally, awareness of personalised medicine among patients and the general public is essential. The translation of the promise of science into reality – from personalised medicine to better quality of life – will not be effective if there is not a proper understanding among patients. Epithelial tissue includes, but is not limited to, the surface layer of skin, glands and a variety of other tissues that line the cavities and organs of the body. To be classifed as adenocarcinoma, the cells do not necessarily need to be part of a gland, as long as they have secretory properties. Well-differentiated adenocarcinomas tend to resemble the glandular tissue from which they are derived, while poorly differentiated adenocarcinomas may not. By staining the cells from a biopsy, a pathologist can determine whether the tumour is an adenocarcinoma or some other type of cancer. Adenocarcinomas can arise in many tissues of the body due to the ubiquitous nature of glands within the body. While each gland may not be secreting the same substance, as long as there is a secretory function to the cell, it is considered glandular and its malignant form is therefore named adenocarcinoma. Carcinogenesis is a process by which normal cells are transformed into cancer cells. It is characterised by a progression of changes at the cellular, genetic and epigenetic level that ultimately reprogram a cell to undergo uncontrolled cell division, thus forming a malignant mass. Empirical medicine is medicine guided by practical experience or observations and not derived from the “scientifc method”. The term empirical treatment is also used when a treatment is started before a diagnosis is confrmed. The most common reason for this is that confrming a diagnosis may take time, and a delay in treatment can harm the patient. An example is treatment with antibiotics, when there may be no time to wait for the results of isolation of the causal factor of infection. However, once the causal factor is identifed and its sensitivity or resistance to treatment with different antibiotics is tested, a doctor can adjust the treatment. In the cancer feld, oncologists in the past treated most patients diagnosed with a certain tumour type with the same drug or drug combination, but not all patients responded to such therapy. More recently, more scientifc data from research has become available, making it possible to move from such empirical treatment to treatment adjusted for particular patient subgroups, based on an analysis of tumour and patient characteristics. It basically refers to functionally relevant modifcations to the genome that do not involve a change in the nucleotide sequence. The exome is a part of the genome formed by nucleotide sequences, called exons, that are encoded by genes. Although the exome represents a very small portion of the genome, mutations in the exome are thought to harbour 85% of disease-causing mutations. A germline mutation is any detectable and heritable variation in the lineage of germ cells. Mutations in these cells are transmitted to offspring, while those in somatic cells are not. A germline mutation gives rise to a constitutional mutation in the offspring, that is, a mutation that is present in virtually every cell. Grade of differentiation refects how much tumour cells differ from the cells of the normal tissue from which they have originated.

In one study with type 2 diabetics with near-normal fasting plasma glucose concentrations buy 30 mg lansoprazole with mastercard gastritis bad breath, 15 g/d of guar gum did not reduce the excessive postprandial glycemic response (Holman et al buy 30mg lansoprazole fast delivery chronic gastritis of the stomach. Although the mechanism for improved glycemic response seen with guar gum in most studies is not entirely clear discount lansoprazole 15mg mastercard gastritis diet in telugu, guar gum has been shown to increase C-peptide response over time cheap lansoprazole 15mg amex gastritis diet 101, thus suggesting enhanced insulin secretion by guar gum (Groop et al. When the standard glucose test was performed after ingestion of 15 g/d of guar gum, improved glucose toler- ance was observed in all but one pregnant women. In addition, guar gum generated significant reductions in mean serum glucose concentrations at 1, 2, and 3 hours after feeding (Gabbe et al. A few studies have demonstrated an increase in fecal bulk and increased stool frequency upon the ingestion of inulin or oligofructose. Fecal weight was increased after consuming 15 g/d of inulin or oligo- fructose (Gibson et al. After 2 to 6 weeks of treatment with 20 g/d of fructo- oligosaccharides or placebo, symptoms of irritable bowel syndrome improved more in the placebo group than in the fructooligosaccharide group; however, there was no difference between the groups after con- tinuous treatment for 12 weeks. Studies on the effect of inulin or oligofructose ingestion on plasma lipid concentrations have provided mixed results. Significant reductions in plasma triacylglycerol concentrations occurred with the intake of 10 g/d of inulin, particularly in those individuals with a baseline triacylglycerol concentration greater than 1. The ingestion of 9 g/d of inulin signifi- cantly reduced plasma total cholesterol and triacylglycerol concentrations in young men (Brighenti et al. In young, healthy males, 15 g/d of nondigestible oligosaccharides (inulin or fructooligosaccharides) did not decrease blood lipids or affect glucose absorption compared to controls (van Dokkum et al. A placebo-controlled parallel study showed that a daily intake of 10 g of inulin significantly reduced fasting insulin concentrations (Jackson et al. Fasting blood glucose concentrations were significantly reduced by 15 mg/dL in type 2 diabetics who were fed 8 g/d of fructooligosaccharides (Yamashita et al. Daily intake of 20 g of fructooligosaccharides significantly decreased basal hepatic glucose production (Luo et al. No difference, however, was observed in the incremental area under the curve for glucose when indi- viduals were fed 50 g of a rice-based cereal containing 0 or 9 g of inulin (Brighenti et al. An important effect of inulin intake is considered to be the production of Bifidobacteria. Bifidobacteria contain high amounts of β-fructosidase, which are specific for the β-(1,2) bond present in inulin and oligofructose. A number of studies in humans have shown that the ingestion of fructooligosaccharides leads to an increase in fecal Bifidobacteria (Bouhnik et al. Bifidobacteria have been shown to promote beneficial health effects in animals (Grizard and Barthomeuf, 1999); however, potential beneficial effects in humans are not well understood. Extracted β-glucans are highly fermentable and therefore their contribution to fecal bulk is minimal (McBurney, 1991). This may contribute, in part, to the lack of an effect in preventing constipation. Oat bran increases stool weight by supplying rapidly fermented viscous fiber to the proximal colon for bacterial growth (Chen et al. In one study, oat gum supplementation (9 g/d of β-glucan) did not significantly decrease serum total cholesterol concentration compared to the placebo, leading the authors to conclude that the cholesterol-lowering capacity of oat gum in healthy young men is weak (Beer et al. In contrast, when hyper- cholesterolemic individuals were fed oat gum providing 5. The long-term effects of such products were tested in men with type 2 diabetes (Pick et al. In one study, individuals with type 2 diabetes were fed meals containing wheat farina, wheat farina with oat gum, or oat bran (Braaten et al. Both the oat bran and wheat farina with oat gum meals reduced the postprandial rise in plasma glucose and insulin concentrations compared to the wheat farina meal without the oat gum. This is an example of the extracted form of oat bran (Functional Fiber) having a similar effect to the native form (Dietary Fiber). Oat gum has also been compared to guar gum with respect to glucose and insulin responses after an oral glucose load in healthy, fasting individuals (Braaten et al. In this study, the glucose and insulin responses to the oat and guar gum meals were nearly identical. Hallfrisch and colleagues (1995) studied glucose responses in 16 women and 7 men with moderately high cholesterol concentrations who supplemented their normal diets with oat extracts in which either 1 or 10 percent viscous β-glucans were added. Glucose responses were reduced at both the 1 and 10 percent β-glucan supplementation level. In a meta-analysis of approximately 100 studies on stool weight changes with various fiber sources, investigators were able to calcu- late the increase in fecal weight due to fiber ingestion (Cummings, 1993). This meta-analysis concluded that pectin ingestion leads to an increase of about 1. In a randomized crossover study designed to compare the effects of pectin (12 g/d), cellulose (15 g/d), and lignin (12 g/d) on stool characteristics in healthy volunteers, pectin did not alter transit time or increase 24-hour stool wet weight, whereas cellulose decreased mean stool transit time and increased mean wet stool weight (Hillman et al. For example, in a 16-week, double-blind crossover study, grapefruit pectin supplementa- tion decreased plasma cholesterol concentration by 7. When 12 g/d of pectin was taken with meals for 3 weeks, there was a mean decrease in total serum cholesterol concentration of 0. When 15 g/d of citrus pectin was provided in metabolically controlled diets for 3 weeks, plasma cholesterol concentrations were reduced by 13 percent and fecal fat excretion increased by 44 percent; however, plasma triacylglycerol concentrations did not change (Kay and Truswell, 1977). Gold and coworkers (1980) did not observe reductions in serum cholesterol concentrations following the consumption of 10 g of pectin with 100 g of glucose. However, total cholesterol and triacylglycerol concentrations were significantly decreased (Jenkins et al. Supple- mentation with 15 g of pectin increased bile acid excretion by 35 percent and net cholesterol excretion by 14 percent in ileostomy patients, whereas 16 g of wheat bran produced no significant changes (Bosaeus et al. Viscous fibers such as pectin have been found to produce a significant reduction in glycemic response in 33 of 50 studies (66 percent) (Wolever and Jenkins, 1993). Tomlin and Read (1988) showed that 30 g/d of polydextrose increased fecal mass without affecting transit time and stool frequency. Achour and coworkers (1994) observed no significant changes in fecal weight or transit time when seven men consumed 30 g/d of polydextrose. When 4, 8, or 12 g/d of polydextrose was provided, fecal weight increased and ease and frequency of defecation improved in a dose–response manner (Jie et al. Findings on the effect of polydextrose intake on fecal bacterial pro- duction are mixed. Achour and colleagues (1994) reported no changes in bacterial mass in the feces of individuals who consumed 30 g/d of poly- dextrose. This lack of difference may be explained, in part, by the findings of Jie and coworkers (2000).

The enormous and continuously evolving complexities of antiretroviral treatment are generally beyond the level of the third year medical student and for that matter most general internists. The marked importance of antiretroviral medication adherence and the potential consequences of erratic or poor adherence. Physical exam skills: Students should be able to perform a physical exam to establish the diagnosis and severity of disease, including: • General appearance regarding atrophy/wasting/cachexia. Laboratory interpretation: Students should be able to recommend when to order diagnostic and laboratory tests and be able to interpret them, both prior to and after initiating treatment based on the differential diagnosis, including consideration of test cost and performance characteristics as well as patient preferences. Communication skills: Students should be able to: • Communicate the diagnosis, treatment plan, and subsequent follow-up to the patient and his or her family. Basic and advanced procedural skills: Students should be able to: • Obtain blood cultures. Management skills: Students should able to develop an appropriate evaluation and treatment plan for patients that includes: • Ordering appropriate laboratory tests. Respond appropriately to patients who are nonadherent to antiretroviral treatment. These relationships are strong, continuous, independent, predictive and etiologically significant, and indicate that reduction of blood pressure reduces these risks. Symptoms and signs of the following disorders associated with secondary hypertension: • Renovascular hypertension. Basic approaches to the pharmacological management of acute and chronic hypertension, including the physiologic basis and scientific evidence supporting these approaches, and causes for lack of responsiveness to therapy. Prevention strategies for reducing hypertension (including lifestyle factors, such as dietary intake of sodium, weight, and exercise level), and explain the physiologic basis and/or scientific evidence supporting each strategy. History-taking skills: Students should be able to obtain, document, and present an age-appropriate medical history that differentiates among etiologies of disease, including: • Duration and levels of elevated blood pressure. Physical exam skills: Students should be able to perform a physical exam to establish the diagnosis and severity of disease, including: • Blood pressure measurements to detect and confirm the presence of high blood pressure. Differential diagnosis: Students should be able to generate a prioritized differential diagnosis recognizing specific history, physical exam, and laboratory findings that suggest a specific etiology of hypertension. Laboratory interpretation: Students should be able to recommend and interpret diagnostic and laboratory tests, both prior to and after initiating treatment based on the differential diagnosis, including consideration of test cost and performance characteristics as well as patient preferences. Communication skills: Students should be able to: • Communicate the diagnosis, treatment plan and prognosis of the disease to the patient and his or her family, taking into account the patient’s knowledge of hypertension and his or her preferences regarding treatment options. Management skills: Students should be able to develop an appropriate evaluation and treatment plan for patients that includes: • Treating acute and chronic hypertension.

A thorough understanding of a systematic approach to hyperbilirubinemia/jaundice is by far preferable to random knowledge of highly specific etiologies. The liver responds pathologically to injury in characteristic ways and knowledge of these patterns can also be very useful in differential diagnosis. Several etiologies of liver disease such as acute/chronic viral hepatitis and alcohol-induced liver disease are sufficiently common as to require specific attention. In addition, many liver diseases can result in cirrhosis and its complications and, therefore, understanding this end-stage development is important.
