Beta-blockers (beta-blockers) have demonstrated their value across the cardiovascular disease spectrum. Beta-blockers effectively lower blood pressure in patients with hypertension and provide symptomatic or mortality benefits in patients with heart failure and in post-myocardial infarction patients. However, despite their utility, beta-blockers remain underused. There have been recent concerns that beta-blockers as a class are not as effective as once thought in uncomplicated hypertension due to a relatively weak effect on reduction of stroke and the absence of an effect on coronary heart disease when compared with placebo or no treatment. Underuse can, in part, be related to tolerability concerns. Beta-blockers have been traditionally associated with side effects including depression, fatigue, sexual dysfunction, and cold extremities, which limit their acceptance by patients and physicians and may lead to discontinuation of therapy. Because of inherent heterogeneity of the beta-blocker class in terms of adrenergic receptor selectivity, intrinsic sympathomimetic activity, and vasodilatory activity, these agents vary in tolerability profile. Recently, more attention has been focused on the third-generation vasodilatory beta-blockers (ie, carvedilol, labetalol, and nebivolol), with the recognition that these agents may diverge in meaningful ways from the traditional beta-blockers. By examining the differences among members of the beta-blocker class, it may be possible to determine whether and which tolerability issues are indeed a class effect of beta-blockers or whether these agents should be evaluated on a case-by-case basis.

Multiple sclerosis (MS) is the most common cause of progressive neurological disability in young adults. In addition to spasticity, tremors, weakness, sensory disturbances, depression, cognitive problems, and bladder or bowel dysfunction, sexual dysfunction (SD) is also a prevalent and destructive manifestation of the disease that severely affects quality of life. Evaluation of this disorder requires insight into the primary (changes that directly affect libido, sexual response and orgasm due to direct damage to the nervous system), secondary (complaints which are related to the physical disability of MS, such as fatigue, muscle rigidity, weakness and spasms), and tertiary (emotional, social and cultural aspects of MS) components of MS-associated SD. Given the complexity and multifactorial nature of SD, a multidisciplinary approach is necessary when treating patients with MS. The aim of this Review is to provide a holistic approach to the evaluation and management of SD in patients with MS, incorporating the latest data from the fields of urology, neurology, nursing, social work, and psychology. What is currently known regarding the evaluation and management of SD in patients with MS will be presented from the perspective of these specialties.

The care of a patient in the intensive care unit extends well beyond his or her hospitalization. Evaluation of a patient after leaving the intensive care unit involves a review of the hospital stay, including principal diagnosis, exposure to medications, period spent in the intensive care unit, and history of prolonged mechanical ventilation. Fatigue should prompt evaluation for possible anemia, nutritional deficits, sleep disturbance, muscular deconditioning, and neurologic impairment. Other common problems include poor appetite with possible weight loss, falls, and sexual dysfunction. Psychological morbidities, posttraumatic stress disorder, anxiety disorder, and depression also often occur in the post-intensive care unit patient. These conditions are more common among patients with a history of delirium, prolonged sedation, mechanical ventilation, and acute respiratory distress syndrome. The physician should gain an understanding of the patient's altered quality of life, including employment status, and the state of his or her relationships with loved ones or the primary caregiver. As in many aspects of medicine, a multidisciplinary treatment approach is most beneficial to the post-intensive care unit patient.

Breast cancer survivors make up a largest proportion of cancer survivors in the United States. This has prompted a concerted effort to address and meet the needs of this ever-growing population, far beyond the emphasis on improvements on therapy. Breast cancer survivors face multiple concerns that span the medical, psychosocial, sexual, and physical realms. Among these issues, concerns related to fatigue and distress, fertility considerations, and sexual dysfunction are perhaps ones that treating oncologists are not as comfortable in discussion and counseling their patients on. This report will focus on these four issues highlighting information for the treating oncologist which can assist in the evaluation, counseling, and treatment for their patients.

Chronic infection with the hepatitis C virus (HCV) has a profound effect on health-related quality of life (HRQoL) - with fatigue, depression and neurocognitive deficits among the most common complaints. Neuropsychiatric symptoms have prompted research to determine whether the HCV acts within the central nervous system. Replicating virus has been found in central nervous tissues, and changes in neurotransmitter levels in the frontal white matter of patients with chronic hepatitis C are correlated with impaired attention and concentration. Other symptoms of chronic hepatitis C that decrease HRQoL include associated sexual dysfunction and depression. Treatment of chronic HCV infection may temporarily worsen HRQoL, and common adverse effects of currently available agents include fatigue, muscle aches, depression and cognitive deficits. The relationship between sustained viral response and improvement in HRQoL is nonetheless well accepted. Although treatment-related adverse effects may dissuade people from starting therapy and reduce compliance with associated reductions in sustained viral response, for the majority of patients viral clearance produces improvements in both HRQoL and long-term prognosis. Novel agents, with improved adverse effect profiles, may afford more patients the opportunity to achieve a sustained viral response.

The efficacy and tolerability of extended-release quetiapine fumarate (quetiapine XR) once-daily monotherapy in generalized anxiety disorder (GAD) was assessed. This multicentre, double-blind, randomized, placebo- and active-controlled, phase III trial consisted of a 1- to 4-wk enrolment/wash-out period and a 10-wk (8-wk active treatment, 2-wk post-treatment drug-discontinuation) study period; 873 patients were randomized to 50 mg or 150 mg quetiapine XR, 20 mg paroxetine, or placebo. Primary endpoint was change from randomization at week 8 in Hamilton Rating Scale for Anxiety (HAMA) total score. At week 8, all active agents produced significant improvements in HAMA total and psychic subscale scores vs. placebo; HAMA somatic subscale scores were significantly reduced only by 150 mg quetiapine XR. Significant separation from placebo (-2.90) in HAMA total score was observed at day 4 for 50 mg quetiapine XR (-4.43, p<0.001) and 150 mg quetiapine XR (-3.86, p<0.05), but not for paroxetine (-2.69). Remission (HAMA total score 7) rates at week 8 were significantly higher for 150 mg quetiapine XR (42.6%, p<0.01) and paroxetine (38.8%, p<0.05) vs. placebo (27.2%). The most common adverse events (AEs) were dry mouth, somnolence, fatigue, dizziness, and headache, for quetiapine XR, and nausea, headache, dizziness for paroxetine. A lower proportion of patients reported sexual dysfunction with quetiapine XR [0.9% (50 mg), 1.8% (150 mg)] than with placebo (2.3%) or paroxetine (7.4%). The incidence of AEs potentially related to extrapyramidal symptoms was: quetiapine XR: 50 mg, 6.8%, 150 mg, 5.0%; placebo, 1.8%; and paroxetine, 8.4%. Once-daily quetiapine XR is an effective and generally well-tolerated treatment for patients with GAD, with symptom improvement seen as early as day 4.

Beta-blockers were documented to reduce reinfarction rate more than 3 decades ago and subsequently touted as being cardioprotective for a broad spectrum of cardiovascular indications such as hypertension, diabetes, angina, atrial fibrillation as well as perioperatively in patients undergoing surgery. However, despite lowering blood pressure, beta-blockers have never shown to reduce morbidity and mortality in uncomplicated hypertension. Also, beta-blockers do not prevent heart failure in hypertension any better than any other antihypertensive drug class. Beta-blockers have been shown to increase the risk on new onset diabetes. When compared with nondiuretic antihypertensive drugs, beta-blockers increase all-cause mortality by 8% and stroke by 30% in patients with new onset diabetes. Beta-blockers are useful for rate control in patients with chronic atrial fibrillation but do not help restore sinus rhythm or have antifibrillatory effects in the atria. Beta-blockers provide symptomatic relief in patients with chronic stable angina but do not reduce the risk of myocardial infarction. Adverse effects of beta-blockers are common including fatigue, dizziness, depression and sexual dysfunction. However, beta-blockers remain a cornerstone in the management of patients having suffered a myocardial infarction and for patients with heart failure. Thus, recent evidence argues against universal cardioprotective properties of beta-blockers but attest to their usefulness for specific cardiovascular indications.

With advances in treatment, colorectal cancer (CRC) is being transformed from a deadly disease into an illness that is increasingly curable. With this transformation has come increased interest in the unique problems, risks, needs, and concerns of survivors who have completed treatment and are cancer-free. Research has shown that physical and mental quality of life for CRC survivors was inferior compared with age-matched individuals without cancer. Although issues and symptoms were most prominent during the first 3 years, long-term effects of treatment can persist and include fatigue, sleep difficulty, fear of recurrence, anxiety, depression, negative body image, sensory neuropathy, gastrointestinal problems, urinary incontinence, and sexual dysfunction. The unique challenges and issues of CRC survivors can and should be addressed by health care providers and the research community to ensure effective interventions and models of care to manage these problems. This article discusses what is known about the long-term effects of CRC treatment on quality of life, the care of survivors, and existing models of survivorship care.

While the completion of therapy is an important milestone in the successful treatment of cancer, many survivors find themselves facing a variety of psychological challenges after their treatment ends. This article highlights some of the most common psychological challenges after cancer therapy such as depression, anxiety, fatigue, and sexual dysfunction. Common risk factors for these challenges will be reviewed and methods for assessing survivors' psychosocial functioning in the context of a medical visit will be discussed. This article also will provide guidance on how to access resources and educational information, and how to make an appropriate referral for follow-up when these psychological challenges are identified.

This study aims to examine and compare changes in quality of life after two common treatments for prostate cancer (PC), radical prostatectomy (RP) and radiation therapy (RT). Patients newly diagnosed with localized PC, scheduled to receive RP (n=68) or RT (n=66), completed three cancer/PC-specific psychometric instruments and three PC-specific utility instruments before treatment, and 2 and 12 months after treatment. We assessed the magnitude and time course of changes in psychometric and utility measures, and differences between treatments. The results showed that RP was associated with significant urinary and sexual dysfunction; RT caused bowel problems. Fatigue and pain were common to both. RP patients reported more problems with physical, role and social function. Utilities decreased significantly after both treatments. Effects were most severe 2 months post treatment, and then showed some recovery, but many endured for 1 year. After 1 year, 30-60% of patients had utility scores that were clinically significantly worse than at baseline. Secondary androgen deprivation therapy also significantly decreased psychometric and utility measures of quality of life. Many adverse symptoms reported 2 months after RP and RT endure for 1 year. Despite different symptom profiles, RP and RT result in similar utility decrements.
