Fatigue due to cancer and its treatments is a highly prevalent and debilitating symptom experienced by many patients. This symptom is often present prior to a pathologically confirmed diagnosis of cancer and can be experienced both during and for considerable periods after treatment. Oncology professionals are becoming more cognizant of the impact of cancer-related fatigue on key aspects of patients’ psychosocial performance, cognitive functioning, and overall quality of life. This paper discusses the importance of cancer-related fatigue, the challenges involved in assessing this debilitating symptom among cancer patients, and the influence of researchers’ conceptualization of this symptom on the characteristics of the measures developed to assess it. Strategies to facilitate differential diagnosis of cancer-related fatigue are also presented and discussed.
Key words: cancer-related fatigue, assessment, measurement dimension, older adults, quality of life.

Approximately 25% of persons with cancer report symptoms that meet the diagnostic criteria for the most prevalent mood disorders, including major depression, dysthymic minor depression, and adjustment disorder with depressed mood. This is two to four times the incidence found among the general population. To simply consider depression as “normal” precludes the possibility that some very good things can happen when patients are properly diagnosed and referred to a psychosocial program to be seen by a psychiatrist, psychologist, or social worker. Asking about a patient’s general mood or spirits needs to become as routine as asking about pain. While screening instruments can be very helpful, single questions are equally useful for identifying patients with this unmet need. Otherwise, patients remain feeling helpless or that their condition is hopeless, and this can easily spiral into despair and significantly worsened depression.
Key words: cancer, depression, psychosocial, supportive care, coping.

The incidence of cancer continues to increase, and many persons receiving treatment for cancer are older adults. Fever in older adults with cancer can be an emergency. Any patient with fever and neutropenia should be given antibiotics as soon as possible. In addition to the immune senescence associated with aging, individuals with cancer have immunodeficiencies specific to their underlying malignancy, and these predispose them to specific infections. Older adults are also at higher risk of the complications of chemotherapy, including infections. Prompt evaluation and judicious management of the febrile cancer patient can reduce morbidity and mortality. The following review considers an approach to the etiologies and evaluation of fever in cancer including the infectious and noninfectious causes.
Key words: fever, cancer, older adults, antibiotics, neutropenia.

Older adults have a high prevalence of urinary incontinence. Among the older adult population, many nonurinary pathological, anatomical, physiological, and pharmacological factors may serve as comorbidities in the development of incontinence. The treating physician must appreciate potentially reversible pathologies. Older adults frequently are prescribed several drugs; therefore, it is important to consider drug-drug metabolic interactions. Age-associated changes may affect pharmacological actions of the drug. Antimuscarinic therapy has been proven efficacious and represents the first line of pharmacologic therapy for overactive bladder (OAB). The selection of an antimuscarinic agent for the management of an older individual presenting with OAB is limited by the natural condition of the aging body and by the side effects associated with antimuscarinics as a class and the specific agents themselves.
Key words: urinary incontinence, antimuscarinics, older adult, frail older adult, geriatrics.

Mobility and independence are essential components of a high quality of life. Although they lack the strength to operate manual wheelchairs, most physically disabled older adults with cognitive impairment are also not permitted to use powered wheelchairs due to concerns about their safety. The resulting restriction of mobility often leads to frustration and depression. To address this need, the authors are developing an intelligent powered wheelchair to enable safe navigation and encourage interaction between the driver and his/her environment. The assistive technology described in this article is intended to increase independent mobility, thereby improving the quality of life of older adults with cognitive impairments.
Key words: mobility, artificial intelligence, assistive technology, wheelchairs, cognitive impairment.

Hallucinations and delusions increase the risk of developing dementia, delirium, functional impairment, and of death. The differential diagnosis includes isolated hallucinations, delirium, depression with psychotic symptoms, late-onset schizophrenia, and unrecognized dementing disorder, including Lewy Body disease and frontotemporal dementia. Optimum management requires diagnosis, assessment of the goals of treatment, and understanding the risks and benefits associated with psychoactive medications. Atypical neuroleptics are appropriate first-line agents for most patients with dementia and psychotic symptoms. Response to medications is modest and a second agent (including acetylcholinesterase inhibitors, antidepressants, and anticonvulsants) may be necessary to reduce behaviour to acceptable levels. In addition, decline in cognitive status and increased risk of cerebrovascular events and death are associated with the use of antipsychotic medications. Change in functional status and time alter the impact of behavioural symptoms. Periodic reassessment and reduction of medication dosage over time appears safe, usually without re-emergence of symptoms.
Key words: psychotic symptoms, older adult, dementia, antipsychotics, behavioural disturbance.

Syncope is a frequent cause for emergency consultation and hospital admission; it is also an indicator of reduced survival rate among older adults. The differential diagnosis may be large, but bradyarrhythmias, neurocardiogenic syncope, carotid hypersensitivity syndrome, and orthostatic hypotension are the more frequent causes. Good history-taking and physical examination usually orient the diagnosis and testing strategy. In working with older patients, great care must be taken in assessing comorbidities and concomitant medications as they can exacerbate syncopal symptoms. A multidisciplinary and dedicated approach to syncope increases the diagnostic yield and rapid management of patients.
Key words: syncope, orthostatic hypotension, arrhythmia, neurally mediated syncope.

Pulmonary arterial hypertension is a rare but incurable disease characterized by a progressive increase in pulmonary vascular resistance and ultimately dysfunction of the right ventricle. Clinically, the reduction in right ventricular output and ensuing right ventricular failure causes severe physical limitation, reduced quality of life, and increased mortality. With the present use of directed therapies such as prostanoids, prognosis is slowly improving. Currently, unique challenges in both clinical assessment and management arise as the population of patients with pulmonary arterial hypertension ages and we better recognize the spectrum of this disease in older adults.

Long-term care-acquired pneumonia is a clinical syndrome of pneumonia that develops in a resident of a long-term care facility who has not been recently hospitalized. It is one of the leading causes of mortality and morbidity among the residents of long-term care facilities. Streptococcus pneumonia, Haemophils influenza, and Moraxella catarrhalis are the most frequently identified bacterial causative. Poor oral hygiene increases the risk of long-term care-acquired pneumonia. In this review, we discuss the risk factors, pathogenesis, etiology, management, and the preventive measures for long-term care-acquired pneumonia.
Key words: Long-term care, nursing home, health care facilities, pneumonia, fluoroquinolones.

At present, some 750,000 Canadians are known to have chronic obstructive pulmonary disease (COPD). This number is believed to represent the tip of the iceberg, as COPD is often only diagnosed in the advanced stage. Respiratory symptoms or a previous smoking history are common among older adults yet they seldom trigger further assessment for COPD. Objective demonstration of airflow obstruction by spirometry is a simple procedure, even in older adults, and is the gold standard for diagnosis of COPD. Early intervention with routine nonpharmacological management includes partnering with the patient and family, providing education, smoking cessation, vaccination, collaborative self-management, and advice on exercise and pulmonary rehabilitation. Anticholinergic inhalers remain the gold standard for optimal bronchodilation and dyspnea relief in COPD, and new long-acting agents have underpinned new treatment algorithms, improving quality of life and exercise capacity as well as reducing exacerbations. For those with advanced disease, recent trials have reported further benefits with the addition of combination inhalers (inhaled corticosteroid and long-acting B2-agonist) to core anticholinergic treatment. Physicians and patients can expect a promising future for COPD treatment as significant advances in management and improved outcomes in COPD are now being made.
