Self-perception of health influences the quality of life of the elderly. In order to identify the more vulnerable elderly and guide interventions to improve health in this population group, we evaluated self-perceived health of elderly people through a set of 4 questions called the "Healthy Days Measures", which were incorporated into the Argento Study. The latter is a study performed to evaluate the health status of the elderly population in 11 Italian regions (2002). Methods. Following cluster sampling, 2,369 elderly subjects (>64 years) were interviewed at home, by trained personnel, through a standardized questionnaire. Self-rated health (on a scale from poor to excellent) was estimated, as well as the average number of days during the previous month when physical or mental health was not good and the number of activity limitation days. Multivariate analysis was performed using Sudaan software and by considering the following outcomes: self-perceived health, physical or mental problems or activity limitations for more than 1 day. Prevalence rates by gender, age, civil status, education level, home situation, place of residence, chronic diseases, dependence on a caregiver, sedentariness and social isolation, were calculated. Results. 34.7% of interviewed subjects rated their health as good to excellent. A significantly lower proportion of women, older subjects (>75 years), those with a lower education level, those residing in southern Italy, those suffering from chronic illnesses, those dependent on a caregiver, and socially isolated or sedentary subjects rated their health favorably. The mean number of physically and mentally unhealthy days (summary index) was estimated to be 11.3 per month. Multivariate analysis showed that female gender was significantly associated with all outcomes considered; age and education level did not show any significant associations with the outcomes considered; depression was significantly associated with self-rated health and with number of mentally unhealthy days; physical dependence and sedentariness were associated with an increased risk for all outcomes, especially activity limitation days. Conclusions. These results suggest that depression, physical dependence and sedentariness influence self-perceived health more so than socio-demographic characteristics. Public Health may have a relevant role in promoting and guiding interventions to prevent these factors in the elderly. The introduction of Healthy Days measures in health surveillance systems may be an important public health tool for monitoring perceived health status and in intervention planning and evaluation at both the national and local levels.

The characterization of the first selective orally active and brain-penetrant beta3-adrenoceptor agonist, SR58611A (amibegron), has opened new possibilities for exploring the involvement of this receptor in stress-related disorders. By using a battery of tests measuring a wide range of anxiety-related behaviors in rodents, including the mouse defense test battery, the elevated plus-maze, social interaction, stress-induced hyperthermia, four-plate, and punished drinking tests, we demonstrated for the first time that the stimulation of the beta3 receptor by SR58611A resulted in robust anxiolytic-like effects, with minimal active doses ranging from 0.3 to 10 mg/kg p.o., depending on the procedure. These effects paralleled those obtained with the prototypical benzodiazepine anxiolytic diazepam or chlordiazepoxide. Moreover, when SR58611A was tested in acute or chronic models of depression in rodents, such as the forced-swimming and the chronic mild stress tests, it produced antidepressant-like effects, which were comparable in terms of the magnitude of the effects to those of the antidepressant fluoxetine or imipramine. Supporting these behavioral data, SR58611A modified spontaneous sleep parameters in a manner comparable to that observed with fluoxetine. Importantly, SR58611A was devoid of side effects related to cognition (as shown in the Morris water maze and object recognition tasks), motor activity (in the rotarod), alcohol interaction, or physical dependence. Antagonism studies using pharmacological tools targeting a variety of neurotransmitters involved in anxiety and depression and the use of mice lacking the beta3 adrenoceptor suggested that these effects of SR58611A are mediated by beta3 adrenoceptors. Taken as a whole, these findings indicate that the pharmacological stimulation of beta3 adrenoceptors may represent an innovative approach for the treatment of anxiety and depressive disorders.

The purpose of this cross-sectional descriptive study was to determine the extent to which wheelchairs prescribed during rehabilitation are used and perceived as satisfactorily meeting individual mobility, functional, psychological and social needs of veterans who have had a stroke. Forty-nine veterans were interviewed during a one-time visit to the Veterans Affairs Medical Center. Questionnaires on demographics, medical status, functional independence, cognition, social integration, depression, health status and well-being, and wheelchair use and satisfaction were administered. Fifteen participants (31%) no longer used their wheelchairs. Primary reasons included improved physical function (93%) and use of alternative mobility aids (87%). Use by continued wheelchair users ranged from less than 1 hour each day (29%) to more than 8 hours each day (3%). Participants who retained use of the wheelchair were satisfied with its performance. Continued use was associated with impaired mobility, physical dysfunction, and physical dependence. Participants who no longer used their wheelchairs had used them an average of 13 weeks. Medical and psychosocial problems unrelated to wheelchair use were common. Almost 45% of the participants had impaired socialization, 80% had severely compromised occupations, and 41 percent displayed mild to severe depression. Although wheelchair use declined for 31% of the participants, primarily as a result of improved physical function, it is evident that a number of wheelchairs were issued at great expense that were no longer needed. This finding, as well as the reporting of problems unrelated to wheelchair use, suggests the need for reevaluation of mobility and psychosocial needs during the years following rehabilitation for a stroke.

Medications which bind to opioid receptors are increasingly being prescribed for the treatment of multiple and diverse chronic painful conditions. Their use for acute pain or terminal pain is well accepted. Their role in the long-term treatment of chronic noncancer pain is, however, controversial for many reasons. One of the primary reasons is the well-known phenomenon of psychological addiction that can occur with the use of these medications. Abuse and diversion of these medications is a growing problem as the availability of these medications increases and this public health issue confounds their clinical utility. Also, the extent of their efficacy in the treatment of pain when utilized on a chronic basis has not been definitively proven. Lastly, the role of opioids in the treatment of chronic pain is also influenced by the fact that these potent analgesics are associated with a significant number of side effects and complications. It is these phenomena that are the focus of this review. Common side effects of opioid administration include sedation, dizziness, nausea, vomiting, constipation, physical dependence, tolerance, and respiratory depression. Physical dependence and addiction are clinical concerns that may prevent proper prescribing and in turn inadequate pain management. Less common side effects may include delayed gastric emptying, hyperalgesia, immunologic and hormonal dysfunction, muscle rigidity, and myoclonus. The most common side effects of opioid usage are constipation (which has a very high incidence) and nausea. These 2 side effects can be difficult to manage and frequently tolerance to them does not develop; this is especially true for constipation. They may be severe enough to require opioid discontinuation, and contribute to under-dosing and inadequate analgesia. Several clinical trials are underway to identify adjunct therapies that may mitigate these side effects. Switching opioids and/or routes of administration may also provide benefits for patients. Proper patient screening, education, and preemptive treatment of potential side effects may aid in maximizing effectiveness while reducing the severity of side effects and adverse events. Opioids can be considered broad spectrum analgesic agents, affecting a wide number of organ systems and influencing a large number of body functions.

Full remission, defined as the absence of all significant symptoms of depression over at least 6 months, is the ultimate goal of antidepressant therapy. Remission takes time and studies have shown that remission rates continue to rise for at least 3 months after initial improvement. Depression is a recurrent condition with a cumulative probability of recurrence of 40% over 2 years and 70% over 5 years after the first depressive episode. In addition the risk of recurrence increases with each new depressive episode. Continuing antidepressant treatment beyond the acute response significantly decreases the risk of recurrence. A double-blind study with the serotonin norepinephrine reuptake inhibitor milnacipran, for example, has shown that patients in remission following treatment with milnacipran who continued the active treatment for a further 12 months had significantly less relapse (P<.05) than those switched to placebo. In spite of the importance of maintaining antidepressant therapy, many patients do not continue treatment. Among the principal reasons for this are side effects and worries of psychological or physical dependence. To reduce the risk of relapse, treatment with effective, well-tolerated antidepressants with few withdrawal effects should be pursued for at least 6 months and possibly longer in patients already experiencing relapse.

One quarter of the prescription drugs sold in the United States are used by the elderly, often for problems such as chronic pain, insomnia, and anxiety. The prevalence of abuse may be as high as 11 percent with female gender, social isolation, depression, and history of substance abuse increasing risk. Screening instruments for prescription drug abuse have not been validated in the geriatric population. Benzodiazepines, opiate analgesics, and some skeletal muscle relaxants may result in physical dependence; however, tolerance, withdrawal syndrome, and dose escalation may be less common in the older patient. Lower doses may decrease the risk of abuse and dependence; however, fear of abuse often results in a failure to adequately treat symptoms such as anxiety, pain, and insomnia.

Cough is a persistent symptom of many inflammatory airways' diseases. Cough is mediated by receptors sited on sensory nerves and then through vagal afferent pathways, which terminate in the brainstem respiratory centre. Cough is often described as an unmet clinical need. Opioids are the only prescription-based antitussives currently available in the UK. They possess limited efficacy and exhibit serious unwanted side effects, such as physical dependence, sedation, respiratory depression and gastrointestinal symptoms. There are three classical opioid receptors: the mu, kappa and delta receptors. Peripheral opioid receptors are sited on sensory nerves innervating the airways. A greater understanding of the role of the peripheral and centrally sited opioid receptors is necessary to allow the development of targeted treatments for cough. Because of the limited efficacy and the side-effect profile of the opioids, potential new treatments are sought to alleviate cough. One class of compounds that is currently under examination is the cannabinoids. Like the opioids, cannabinoids have peripheral and centrally sited receptors and also suffer from the blight of unwanted centrally mediated side effects such as sedation, cognitive dysfunction, tachycardia and psychotropic effects. Two cannabinoid receptors have been identified, the CB(1) and CB(2) receptors, and their distribution varies throughout the peripheral and central nervous system. Encouragingly, early studies with these compounds suggest that it may be possible to separate their antitussive activity from their centrally mediated side effects, with CB(2) agonists showing potential as putative new treatments for cough. In this chapter, we describe the opioid and cannabinoid receptors, their distribution and the effects they mediate. Moreover, we highlight their potential advantages and disadvantages in the treatment of cough.

Simple, rapid and inexpensive rodent models of nicotine physical dependence and withdrawal syndrome have proved useful for preliminary screening of smoking cessation treatments. They have led to an exponential increase of knowledge regarding the underlying neurobiological mechanisms of dependence and withdrawal syndrome. The human nicotine withdrawal syndrome in smoking cessation is variable and multidimensional, involving irritability, anxiety, depression, cognitive and attentional impairments, weight gain, sleep disturbances, and craving for nicotine. Aside from sleep disturbances, analogous phenomena have been seen in rodent models using different measures of withdrawal intensity. It appears likely that different withdrawal phenomena may involve some partially divergent mechanisms. For example, depression-like phenomena may involve alterations in mechanisms such as the mesolimbic dopamine pathway from the ventral tegmental area to the nucleus accumbens. Irritability and anxiety may involve alterations in endogenous opioid systems and other regions, such as the amygdala. This chapter reviews many additional anatomical, neurochemical, and developmental elements that impact nicotine physical dependence.

Tobacco use is the single most preventable cause of death, disability and disease in the world and is projected to be the leading cause of death and disability across all developed and developing countries by 2020. Nicotine, the primary active ingredient of cigarettes that contributes to physical dependence, acts on nicotine receptors in the central nervous system and leads to the release of neurotransmitters (such as dopamine). Like other drugs of abuse, nicotine is thought to produce reinforcing effect by activating the mesocorticolimbic dopamine system. A wide variety of cessation treatments of nicotine dependence is commercially available, yet only 2 general approaches have received empirical validation: behavioral intervention (including 5 As brief intervention) and pharmacotherapy. The evidences show that 5 As brief intervention is one of the most cost-effective treatments in clinical work for busy physicians. Three types of medications have been available in market for smoking cessation treatment: nicotine replacement treatment (NRT, i.e., transdermal patch, gum, inhaler, nasal spray, and lozenge), sustained release bupropion and varenicline. Varenicline, a novel alpha4beta2 nicotinic receptor partial agonist, is effective for tobacco dependence. Phase III trials suggest that it is more effective than NRT and bupropion SR. The safety profile of varenicline is excellent, with the most commonly occurring adverse events, nausea, typically mild and well tolerated. However, new safety warnings are added to the varenicline label because of post-marketing report including agitation, depression and suicidality. A causal connection between varenicline use and these symptoms has not been established.

Recent statistics from the World Health Organization indicate that a high percentage of people worldwide suffer from a wide variety of acute or cancer-associated chronic pain. At present, with a few exceptions, the treatment of severe pain relies upon oral administration of the mu-opioid receptor-targeting opiate morphine and its surrogates under strict clinical control. In spite of the powerful in vivo efficacy of these drugs, their long-term use is limited by antinociceptive tolerance, physical dependence, and respiratory depression that evolve. As no analgesics with moderate side effect profiles are currently available for the therapy of different types of pain and stages of cancer, considerable efforts must be made in the search for opiate substitutes. Following the recognition that endogenous peptide ligands of the opioid receptors exert striking effects in various pain models, and with the recent advances in chemical synthesis methods, research interest has steadily moved toward peptide-based compounds as potential opioid analgesics. The endomorphins are an attractive set of endogenous opioid peptides that may meet the requirements of opioid-based pain management. By virtue of their excellent mu-opioid receptor labeling and favorable analgesic properties, these tetrapeptides have gained attention in recent years as potential lead compounds. The ever-increasing number of publications in this field strongly suggests that modified analogues of endomorphins could serve as potent substitutes for opiates, with a lower propensity to induce side effects. This review surveys the main results achieved over the past decade regarding the design, radiolabeling, pharmacological characterization, and structure-activity features of a large body of endomorphin derivatives.
