C H A P T E R 7 Pharmacogenetic Factors That Affect Drug Metabolism and Efficacy in Type 2 Diabetes Mellitus X. Patients with high blood sugar levels may lead to symptoms like frequent urination, increased thirst, and increased hunger. Poorly controlled high blood sugar will lead to many acute and long-term complications for the patients with diabetes, including diabetic ketoacidosis, nonketotic hyperosmolar coma, possible blindness, foot ulcers, cardiovascular disease, stroke, and kidney failure (Kitabchi et al. According to the statistics, diabetes affects 347 million individuals worldwide in 2008 (Danaei et al. Pharmacological approach is indispensable when lifestyle changes are not sufficient to alleviate the clinical symptoms for the patients with diabetes. Sulfonylureas can dramatically improve glycemic control and should be considered as the initial treatment for patients with poor glycemic control on an appropriate diet (Pearson et al. Oral sulfonylurea therapy is safe and effective for a short term in most patients and may successfully replace treatment with insulin injection (Rafiq et al. For glibenclamide, the clearance was reduced by 25% and 57%, respectively (Kirchheiner et al. They stimulate first-phase insulin release in a glucose-sensitive manner (Holstein and Beil, 2009), theoretically reducing the risk of hypoglycemic events (Holstein and Egberts, 2003; Dornhorst, 2001; Pearson, 2009b). Most of the commonly used meglitinides are metabolized in the liver and mainly excreted through the bile, except for a small proportion of the parent compound that has been found in the urine. However, the study results of rs12208357 and rs72552763 variants were sometimes different (Zhou et al. Except for rs555657341, all of variants mentioned above reflected a decreased transporter activity in vitro. Subsequently, few studies tried to verify this result in multiple ethnic groups, but the conclusions were controversial. The carriers of allele T of rs149711321 had decreased post-HbA1c levels compared with patients with the allele C after treatment with metformin. Previous studies suggested that Calpain-10 may affect both insulin resistance and insulin secretion (Brown et al. The reduction in HbA1c of carriers of the minor G allele was associated with a smaller reduction in HbA1c (Tkac et al. After 48 weeks of rosiglitazone treatment, rs2230806 was found significantly correlated with rosiglitazone efficacy. A total of 250 patients treated with pioglitazone (30 mg/day) for 24 weeks on the basis of previous medications were recruited. Forty-one patients with different rs2970847 or rs8192678 genotypes received oral rosiglitazone (4 mg/day) for 12 consecutive weeks were enrolled in their study.

Example strategy: Provide the patient with verbal support that builds self-efficacy antibiotic zithromax and alcohol buy azithrocin 100 mg mastercard. Observational learning Engaging in and maintaining new health behaviors by the patient looks for support and encouragement from (modeling) watching the behaviors of others and their outcomes those who have successfully changed a health behavior antibiotic vancomycin side effects buy 100 mg azithrocin with visa. Other strategies include reinforcements that modify behav ior antibiotics for uti breastfeeding cheap 500 mg azithrocin mastercard, or tools bacteria nucleus discount azithrocin online amex, resources, and environmental changes that make new behaviors easier to perform. People are seen as so dynamic that it is difficult to use the theory in its entirety. Instead, most health care providers tend to focus on one or two constructs, such as selfefficacy or observational learning. Finally, the theory has limited value for some diseases, such as dementia, which has more to do with chemical imbalances in the brain than low self-efficacy. The theories and models of health behavior discussed thus far in this chapter share some similarities: Health behavior change is a process. One central construct to these theories and models is that behavior change is a process, not a one-time event. For example, most obese people cannot change their unhealthy eating habits all at once. Even when there is a good first attempt to change health behaviors, relapse is common. For example, it is common practice for someone to start a low-fat diet, only to give up on it after a few months. Making a behavior change and then keeping to that change requires different strategies at different levels of influence. For example, someone could quit smoking by going "cold turkey," but he or she will be tempted again, perhaps just by being around family members who smoke. These barriers exist when a person weighs the pros and cons of changing his or her behaviors; and, because changing a behavior can be so difficult, it has to be worth it. Community Organization Although health behavior theories and models are useful, relying only on them is often not practical. People find it difficult to make health behavior changes in the face of unhealthy social and physical environments. Community organization addresses this issue of unhealthy environments and is an important consideration when helping patients (Glanz & Rimer, 1999: McKenzie et al. Community organization is a process whereby community members identify issues, set goals, and mobilize resources (Berthold, Miller, & Avila-Esparza, 2009; Glanz & Rimer, 1999; McKenzie et al. They then develop and implement strategies for resolving their issues or for reaching their goals. Community organization is dependent on social action-community members coming together for a cause, especially one that involves a group that is being affected by a particular issue. Examples of this are activists who work in the arenas of gay rights, gun control, or human rights. There are also communities of shared cultural identity-for example, Jewish, Irish American, or Mexican American. This knowledge leads to the delivery of health care that is for patients-not for providers. However, community organi zation theories and models require the strength of local leaders and the demands of community stakeholders to make these changes. Community stakeholders are people in the community who are affected, or could be affected, by a community issue. They are individuals, groups, organizations, government departments, businesses-anyone with a stake or an interest in a community issue and its outcome (Berthold et al. Although there is not one theory or model for community organization, there are several key elements (Berthold et al. The goal of community development is to improve environmental, economic, and social conditions within the community. Active local leadership and engaged community stakeholders work together to achieve this goal. Community development strategies include community participation, goal setting, problem solving, planning, and capacity building. Community stakeholders develop working relationships with each other, joining together to identify community issues, mobilize, and take action to resolve those issues. Community stakeholders create goals and strategies to problem-solve, sometimes with "experts" who provide technical assistance. Community assess ment is a strategy through which community stakeholders gather information to understand the causes and consequences of issues. Then, with community leaders, they get together to discuss the situation and develop a plan to resolve these issues. Community leaders and stakeholders increase their ability to resolve community issues and to make changes. Once the issue is resolved, an additional action plan is put in place to make sure that the changes last over time. Community organization can result in change that is effective and sustained over time (see Table 5. There are many examples of how community organization has a lasting positive impact on the health behaviors of community members, including organizing for more community parks or bike paths, for community gardens, and against gun violence. Some of the limits of community organization include the difficulty in getting started, building and maintaining interest, and evaluating success. Community organization can be politically charged, and, at times, communities and their health issues can suddenly change because of a new health crisis, lack of resources, a downturn in the economy, or even a natural disaster. Disease Management Every day, patients make health decisions-for example, taking medicines or keeping medical appointments.
