At the time, we wondered how the audi- ence would react to a book with a title like Overcoming Anxiety For Dummies. But we were surprised and gratified at the overwhelmingly positive responses we got from the majority of readers who contacted us. People all over the world e-mailed us to say that they had found this book to be one of the most comprehensive and accessible books on anxiety they had ever read. Some told us that for the first time in their lives, anxiety no longer dominated their lives. We were also thrilled to discover that many counsel- ors, therapists, and psychologists reported using the book as a supplement to psychotherapy sessions for their anxious patients. When our editors approached us about updating Overcoming Anxiety For Dummies, we took some time to think about what had happened in the world since we wrote the first edition. As we reflected on this issue, we realized that the world has changed a lot in the nine years since the first edition appeared on bookshelves. Because of these growing, emerging sources of worry, we felt a need to include information in this book that addresses them. For example, some airport security areas now have equipment that takes a virtual naked picture of you as you enter. We’ve suffered through what’s cur- rently called the Great Recession, and at the time of this writing, it’s unclear where the world economy is headed. People worry about getting jobs, keep- ing jobs, and fragile dreams of retirement. The globalization of economies and travel have made the spread of pandemics faster and potentially more deadly than ever. The spread of nuclear weapons continues, and worries abound about war, crime, and terror. But just as we don’t want to become victims of terror, we can’t let ourselves become vic- tims of anxiety. We realize that some anxiety is realistic and inescapable; yet, we can keep it from dominating our lives. Even under duress, we can pre- serve a degree of serenity; we can hold onto our humanity, vigor, and zest for life. Because we believe in our collective resilience, we take a humorous, and at times irreverent, approach to conquering anxiety. Instead, we present a clear, rapid-fire set of strategies for beating back anxiety and winning the war against worry. First, we want you to understand just what anxiety is and the different forms it can take. Second, we think that knowing what’s good about anxiety and what’s bad about it is good for you. Finally, we cover what you’re probably most interested in — discovering the latest techniques for overcoming your anxiety and helping someone else who has anxiety. For example, if you really don’t want much information about the who, what, when, where, and why of anxiety and whether you have it, go ahead and skip Part I. However, we encourage you to at least skim Part I, because it contains fascinating facts and information as well as ideas for getting started. An Important Message to Our Readers Since the first edition of Overcoming Anxiety For Dummies, we’ve made a point of commenting on our use of humor in these books. Although topics like anxiety, depression, obsessive-compulsive disorder, and borderline per- sonality disorder are serious, painful subjects, we believe that laughter, like a little sugar, helps the medicine go down and the message come through. Introduction 3 This book is meant to be a guide to overcoming a mental state or disorder called anxiety. However, if your anxiety greatly interferes with your day-to-day life, restricts your activities, and robs you of pleasure, we urge you to seek professional mental healthcare. Conventions Used in This Book We use a lot of case examples to illustrate our points throughout this book. Please realize that these examples represent composites of people with vari- ous types of anxiety disorders. We bold the names of people in our examples to indicate that a case example is starting. We also use boldface text to indicate keywords in a bulleted list or to high- light action parts of numbered steps. Finally, when we direct you to a Web site for additional information, it’s printed in monofont. What You’re Not to Read Not only do you not have to read each and every chapter in order (or at all, for that matter), you don’t have to read each and every icon or sidebar (the text in the gray boxes).
This has made identification of studies 6.25 mg coreg otc, data abstraction purchase coreg 12.5 mg with mastercard, synthesis of evidence, and presentation of findings challenging. Many study reports did not include important information that would have made this report stronger. Interventions most frequently targeted prescribing and monitoring stages of the medication use process. Physicians who provided care in the hospital and ambulatory care settings were most likely to be the target of the intervention. Workflow, communication, interaction with peers and time considerations were found to be improved less often. This was particularly true when patient-centered principles were employed, such as providing patients with reminders and decision support recommendations about their current health status. Differences in study outcomes for similar qualitative studies across settings were not apparent, suggesting that findings from qualitative studies could be transferrable across settings. From qualitative studies, system design including workflow changes, challenges with the system interface and new communication processes demonstrated that without adequate attention to system changes, the new kinds of medical errors with potential detrimental impact to patient safety could occur. Cost analyses can provide useful information on ‘upfront’ costs compared with ‘downstream’ cost avoidance if they explicitly measure all direct health care costs (e. The full enumeration of the total costs needs to be synthesized with the consequences or outcomes of the intervention (i. Adoption of newer technologies needs to be based on formal evaluation of whether the additional health benefit (effectiveness) is worth the additional cost. Unintended consequences, both positive and negative, were found across many of the studies as main endpoints, or were alluded to in others. A tracking system of major and clinically important unintended consequences would be useful for many audiences and should be considered by system developers and funding agencies. Clinicians, administrators, and likely patients and their families have different values and place varying importance on each. Both facilitators and barriers exist that impact movement to implementation of e-Prescribing and two-way communication designed to enhance and streamline prescription optimization. Although we tried to be thorough in our search methods, we feel that we did not capture all potential articles—a very difficult task in new and multidisciplinary areas of study. Further, we concentrated only on the main or major endpoints reported in studies with comparison groups and hypothesis testing. Given the heterogeneity in the literature, it was often difficult to discern main endpoints; where possible we determined main endpoints as those declared as such, or those that were the basis of power calculations (infrequently), or were stated to be main outcome measures in the abstract or objectives. In these cases we gave priority to outcomes related to medication management and clinically important patient outcomes. It has proven difficult to synthesize the evidence on such a range of technologies, implemented in a number of settings and used by various stakeholders. Each intervention is so complex that it is often difficult to tell which studies are assessing the same processes. For example, similar outcomes such as prescribing changes were measured as changes in daily doses; prescribing rates per hospital, per physician, per 1,000 patient days, etc. The number of orders and compliance rates were difficult to extract and synthesize. Our ability to draw conclusions is also reliant on the quality of the evidence we have found. Only a small minority of these studies focus on clinical outcomes—the endpoints that are most important to guide decisions by patients, providers and policymakers, about adopting these interventions. A large number of studies neglected to report the study dates 106 (see Evidence Tables in Appendix C). Although the absence of a contemporaneous comparable control group is a problem with all observational studies, the creation of control groups by comparing intervention patients to those that do not participate, or do not have a problem to those that do is fundamentally far more likely 18 to introduce major bias in the comparison (e. Many observational studies suffered from selecting an outcome that was distantly or only marginally related to the intervention. Moreover, in a substantial proportion of negative studies, minimal adoption was seen. The clinicians failed to adjust therapy or treatment based on recommendations, and thus it is not very surprising to find that the interventions had no effect on outcomes. Finally, the rate of some outcomes such as readmission, mortality, and nosocomial infections was too low to detect clinically meaningful differences if they had existed with the numbers involved in the study. We searched for literature across many domains and reviewed a substantial number of studies. The implications of the report fall within the purview of future research, policy, and evaluation. Certainly the burden of evidence is towards positive effects on process changes and measures of satisfaction and perceived benefits among users. These early indications are logical precursors to changes in demonstrated effects in benefits such as quality of care and clinical outcomes, economic benefits, or both as the technologies advance and mature. A lack of proven effectiveness in improving patient outcomes and a lack of studies on value and cost-effectiveness still exist.
This expe- rience naturally curbs the interest of the pharmaceutical industry in pursuing research in this area generic 6.25 mg coreg visa. From an anthropomorphic per- spective cheap coreg 12.5 mg on line, however, no microbiologist can keep from admiring the ingenuity and efﬁciency that bacteria show in protecting them- selves from the toxic effects of our antibiotics. How does this resistance evolution work, and what are the precise molecular mechanisms for antibiotics resistance? New antibiotics in the true sense—that is, antibacterial agents with new points of attack at the molecular level—have been very limited in number in later years, and this is probably due to the tepid interest of the pharmaceutical industry in this area, for understandable reasons. If the antibacterial agent is effective, the infection heals quickly, and treatment can be terminated. As mentioned earlier, resistance as a rule occurs within one or two years after the introduction of a new antibacterial agent. These circumstances mean that antibiotics are not very interesting from a marketing point of view. Mammalian cells, our cells, are not endowed with that sequence of enzymic reactions necessary to synthesize folic acid, but rely on folic acid as a vitamin in our nourishment. Speciﬁcally, sulfonamides (formula 3-1)were shown to interfere with the bacterial formation of folic acid by its structural similarity to the intermediate p-aminobenzoic acid (3-2). Sulfonamide is generally mentioned in the plural form because dozens of derivatives (modiﬁcations at the amino group at the sulfon residue) of Domag’s original sulfanilamide have been synthesized through the years. In Scandinavia, the distribution of sulfonamides as a single drug for systemic use is presently nil. Aside from preparations for external use, as in ointments, the minimal distribution of sulfonamides that still occurs is in combination with trimethoprim. First, other and in many cases more efﬁ- cient antibacterial drugs became available through the decades following the introduction of sulfonamides in 1935. The third and most important reason, however, was the development of allergic side effects from the blood-forming organs and the skin in many patients. Systematic clinical studies have shown the occurrence of sulfonamide-induced blood dyscrasias, including aplastic ane- mia, at a frequency of 5. As an example, in Sweden there was a trial between a patient association and a pharmaceutical company, culminating in a settlement with high compensation costs for damages, that more or less ended the systemic use of sulfonamides in that country. It could be debated whether the present situation, with its increasing fre- quencies of resistance against antibiotics, might not warrant a reintroduction of sulfonamides for use against that large number of pathogens that still are susceptible to sulfonamides, now with new knowledge and vigilance regarding allergic side effects. The next-to-last step is catalyzed by the enzyme dihydropteroate synthase, which is the target of sulfonamides. Resistance toward sulfonamides is now also very common among gram-negative enterobacteria infecting the urinary tract. The molecular mechanisms of sulfonamide resistance differ markedly between different bacteria and have become investigated only in relatively recent years. The simplest mechanism includes mutational changes in the sulfonamide target enzyme dihydropteroate synthase (Fig. Dihydropteroate synthase catalyzes the next-to-last step in the enzymic pathway leading to folic acid. The structural similarity between sulfonamide and p-aminobenzoic acid and the high afﬁnity of sulfonamide to the enzyme effects a competitive inhibition of dihydropteroate formation and, in turn, of folic acid formation. If a spontaneous mutation hits the chromosomal gene expressing dihydropteroate synthase, changing the enzyme structure such that it binds sulfonamide less tightly, the compe- tition with p-aminobenzoic acid will be less pronounced, and its host then shows sulfonamide resistance. Single colonies, about one in 100 million of totally spread bacteria, showed resistance and grew out to colonies. The nucleotide sequence of the dihydropteroate synthase gene in those resistant bacteria showed that a spontaneous point mutation had occurred, exchanging one nucleotide and in turn exchanging one amino acid in the enzyme expressed. This means that the concentration of sulfonamide has to be increased 150-fold compared to that needed for the same inhibition of the nonmu- tated enzyme. It could be seen, however, that the host bacterium had had to pay a price for its resistance, in that the mutationally changed enzyme needed a 10-fold higher concentration of its normal substrate, p-aminobenzoic acid, to function optimally (a 10-fold increase in the Km). The presence of sulfonamide creates an acute survival situation in which a mutationally changed enzyme is selected to help bacteria survive, but at the price of a less efﬁ- cient enzyme differing from the optimal structure selected during the long evolution of bacteria. This would mean that bacteria reverting to their original susceptibility ought to be selected in the absence of sulfonamide. These arguments regarding molecu- lar evolution and antibiotics resistance are very important for the medical assessment of resistance against antibacterial agents in health care (see Chapter 11): for example, the question of whether antibiotic resistance seen in clinical contexts incurs a ﬁtness cost on the host bacterium, thus counterselecting against resistant bacteria in the absence of antibiotics. Resistance to Sulfonamides in Neisseria meningitidis We now provide a detailed characterization of sulfonamide resistance in Neisseria meningitidis. It includes kinetic character- istics of those resistance variations of dihydropteroate synthase observed in clinical isolates of resistant pathogens, studied with site-directed mutagenesis. It is meant as an illustration at the molecular level of what has happened to a cheap and efﬁcient antibacterial agent under the evolution of resistance. This and the emergence of other more efﬁcient agents has meant that sul- fonamides have not been used for this disease for decades, which ought to mean that sulfonamide-resistant isolates of N.
Alternatively you may lie down on a bed and simply breathe from the diaphragm with your eyes closed coreg 12.5 mg cheap. Place one hand over your chest and another on your abdomen to help guide you to breathe from your diaphragm buy 12.5 mg coreg otc. If you find that your belly won’t move out yet your chest continues to, try this: Lie on your back with your knees bent and put a heavy book on your mid-abdomen approximately over the belly button. The book will help to focus your mind 64 • Mindfulness Medication on expanding the abdomen. Focus your attention on allowing the book to rise as you breathe in and fall as you breathe out. Throughout the day, use your normal daily activities or specific times to remind you to breathe from your belly. Put up Post-it notes in different locations as a reminder to yourself to emphasize diaphragmatic breathing. Set the alarm on your watch, computer or cell for every two to three hours to remind you to bring your attention to diaphragmatic breathing. Try to follow your breathing for a minimum of five breaths at specified times or whenever you see one of your reminders. When you’re under stress bring your attention to your breath and start to consciously breathe in a calm, deep, smooth, even and quiet manner from the diaphragm. Count your breaths and continue breathing from your diaphragm until the stress goes away. The more you practice diaphragmatic breathing the more it becomes a regular habit. A new pattern of deep, smooth, even diaphragmatic breathing will then become the way you normally breathe throughout the day. You really can change how your body and mind respond to stress one breath at a time. Step 4: Exhalation In the final step of your breathing program you are going to look at how exhalation, or the act of breathing out, is a very effective tool for promoting mental and physical relaxation. The autonomic nervous system is the boss of your heart rate, blood pressure, breathing and other bodily functions that, thankfully, carry on without you having to think about them. You don’t have to tell your heart to beat faster when you run, or slow down when you relax. But the autonomic nervous system is always paying attention for you and if you’re feeling Mindfulness and the Breath • 65 stressed, even a little bit, it’s already getting your body prepared to fight, or run, or do whatever you might need to do. This stress keeps you in a “fight or flight” mode constantly, which is exhausting work for your poor nervous system. Your autonomic nervous system is not something you can directly control; your heart beats; you breathe; your digestion carries on without you having to think about any of these activities. Your breathing turns out to be the link between you and your autonomic nervous system. When you inhale, or breathe in, it stimulates the part of your autonomic nervous system, called the sympathetic nervous system, which is responsible for getting you ready for stress. Luckily, when you exhale, or breathe out, it turns on the part of the nervous system called the parasympathetic system, which tells everything to calm down. If you can make the amount of time that you breathe out longer than the time it takes to breathe in, you’re intentionally instructing your autonomic nervous system to relax. Focus your attention on your breath and simply count approximately how many seconds it takes for you to breathe in and then count how long it takes for you to breathe out. You’ll probably observe that the time taken to breathe in and the time taken to breathe out is not always equal, and that this pattern changes depending upon your mental state. See if you can consciously prolong the exhalation such that the time it takes to breathe out is longer than the time it takes to breathe in. You may even intentionally try to prolong the exhalation for as long as it feels comfortable. Close your eyes and consciously breathe with a prolonged exhalation (a longer out- H breath). How do you feel mentally and physically after a few minutes of prolonging the exhalation of your breath? The following is a series of exercises that will help increase your awareness and usage of the out-breath. For approximately ten minutes in the morning and/or ten minutes in the evening sit upright, in a relaxed manner, in a chair. This means that the exhalation, or the act of breathing out, takes longer than the inhalation, or breathing in. Throughout the day, use normal daily activities as a reminder, or set time cues, to remind you to bring your awareness to your exhalations. Put up Post-it notes in different locations as a reminder to yourself to emphasize exhalation. Set the alarm on your watch, computer, or cell phone for every few hours to remind you to bring your attention to your breath. Try to follow your breathing for a minimum of five breaths at specified times, or when you see one of your reminders, just as you did in the previous breathing exercises.
