Recent Developments in the Assessment and Management of Hypertension: CHEP, ALLHAT and LIFE

Recent Developments in the Assessment and Management of Hypertension: CHEP, ALLHAT and LIFE

Teaser:

Poor blood pressure control, particularly among the older Canadian population, remains an important cause of preventable cardiovascular morbidity and mortality. It behooves Canadian health care workers to identify, treat and control hypertension. Recent trials, including ALLHAT and LIFE, add to the information clinicians need to achieve these targets. ALLHAT establishes the central role of thiazide-like diuretics for many hypertensive patients. ALLHAT demonstrates that good blood pressure control can be achieved in the majority of hypertensive patients if a systematic effort is maintained. LIFE adds important information regarding angiotensin receptor blockers as an effective alternative to the other commonly used classes of antihypertensive drugs, particularly among patients with diabetes or isolated systolic hypertension. Finally, the Canadian Hypertension Education Program will continue to produce and disseminate annually updated systematic reviews and recommendations related to the assessment and management of hypertension.
Key words: hypertension, recent clinical trials, clinical practice guidelines.

Inflammatory Bowel Disease in the Elderly

Inflammatory Bowel Disease in the Elderly

The inflammatory bowel diseases (IBD)--Crohn's disease (CD) and ulcerative colitis (UC)--have a second peak of onset after the age of 60. Discerning IBD from alternate diagnoses is a great challenge in the geriatric population, as other diseases commonly encountered in the elderly can mimic IBD. The possibilities include ischemic colitis, diverticulitis and infectious colitis. Diagnosing and treating IBD should involve consultation with a gastroenterologist, but the approaches do not vary significantly from the strategies used in younger patients. Therapeutic modalities used in younger age groups are also applicable to the geriatric population, but great attention needs to be given to side effects and drug interactions.
Key words: inflammatory bowel, crohn's disease, ulcerative colitis, differential diagnosis

Epidemiology and Pathophysiology
The inflammatory bowel diseases--Crohn's disease (CD) and ulcerative colitis (UC)--are illnesses of unknown cause.

The time has come to put to rest the barbs and criticisms of the naysayers who either question or outright deny that the andropause exists. It is also time to put to rest the hesitation and discomfort some may have with the terminology, andropause. Andropause exists and andropause is its name, and many of yesterday's naysayers are among today's converts.

The Four "Pauses"
Perhaps the easiest way to envisage andropause is to view it as one of the four major "--pauses" in the endocrinology of aging.1 There are many theories as to why we age and many studies trying to understand the molecular basis of aging. Yet whatever the underlying mechanisms finally turn out to be, there are at least four significant alterations of endocrine function, each of which has been designated the suffix "pause". Whether or not this is an appropriate designation or the most descriptive of each of these endocrine changes is a moot point. The names transmit concepts that we can recognize and study, and that we can influence, if needed, with therapeutic strategies.

The most well known of the four "pauses" is menopause. Menopause is the culmination of a process that occurs over several years.

affiliated with the Regional Geriatric Program Central Ontario.

Objective: To determine the top learning needs of local specialized geriatrics services staff.
Participants: Health care professionals within the Regional Geriatric Program central area.
Methodology: A snowball sample (n=67) ranked five of 20 possible learning needs (derived from a literature review) by priority.
Analysis: Responses were sorted by those listing a particular subject in any priority, those making it the top priority, and Q-sort.
Results: The top three learning needs--scoring highest on all techniques--were management of dementia, risk and discharge from hospital to community.
Conclusion: This appears to be a viable method of appraising needs for education planning.
Key words: geriatrics, continuing education, survey, needs assessment, Q-sort

Dementia and Wandering Behaviour in Long-term Care Facilities

Nearly half of all residents in long-term care settings suffer from some type of dementing illness, with Alzheimer disease by far the most common type. People with dementia should be presumed at high risk for wandering due to their cognitive deficits and unpredictable behaviour. Recommendations are shared to minimize attempts to wander and actual wandering episodes by promoting a more therapeutic environment both through the physical structure and through staff training. In addition, effective strategies to follow in situations when a resident is, in fact, missing are presented.
Key words: dementia, wandering, long-term care, environment.

Treatment of Hyperglycemia in the Elderly

This article presents a summary of recent recommendations for the diagnosis and treatment of Type 2 diabetes in the elderly. Onset of nephropathy, neuropathy and retinopathy can be slowed by treatment designed to reach realistic target values for fasting plasma glucose and HbA1c. Therapy also should minimize the dangers of hypoglycemia. Hepatic and renal function must be monitored when selecting drugs and dosages. Significant reductions in renal function may be associated with serum creatinine within the normal reference range. A stepwise approach to therapy beginning with diet and exercise and proceeding to single and multidrug treatment is outlined. The mode of action, advantages, disadvantages and contraindications for five groups of hypoglycemic agents are summarized.
Key words: Type 2 diabetes, diagnosis, stepped treatment, oral drugs, elderly.

Iron deficiency anemia is the most common cause of anemia encountered in clinical practice. In elderly patients, iron deficiency anemia is most commonly due to gastrointestinal blood loss, but also can be caused by poor iron intake or malabsorption of iron. Therefore, a careful evaluation of the gastrointestinal tract is warranted in all elderly patients with iron deficiency anemia. Upper endoscopy and colonoscopy can detect clinically important lesions in up to 44-84% of patients. In those who do not have a cause of iron deficiency anemia identified by endoscopy, the prognosis is excellent. Treatment includes iron supplementation and careful monitoring of hemoglobin levels.
Key words: iron deficiency, anemia, endoscopy, gastrointestinal bleeding, iron malabsorption.

The increase in male life expectancy has raised concerns about the impact of aging on the male reproductive system. Male testicular function declines gradually with advancing age. In general, testicular perfusion is reduced, aging pigment is accumulated, and the tunica albuginea of the testes and basal membrane of the seminiferous tubules are thickened. The function of Sertoli cells and Leydig cells declines. Among the semen parameters, semen volume, sperm motility and sperm morphology are decreased. The hypothalamic-pituitary-gonadal axis is affected at all levels. In some aging men, the reduction of testosterone levels leads to sexual dysfunction and "andropause". Children born to older fathers carry a higher risk of genetic diseases. This review focuses on the effect of aging on the male gonads.
Key words: aging, gonads, fertility, testosterone.

Whether women are taking hormone replacement therapy for the prevention of heart disease, osteoporosis or the symptoms of menopause, results from the Women's Health Initiative (WHI) study have brought to the forefront many concerns. Results from this as well as the HOPE study are reviewed, followed by the ensuing responses and recommendations from medical societies. Assessing and tailoring hormone replacement therapy for every woman individually is what can be recommended clearly until further studies are published.
