The goal of this study is to determine the prevalence of 23 common diseases in subjects with a chronic airway obstruction and in controls. All subjects with a known diagnosis by their general practitioner of asthma or chronic obstructive pulmonary disease (COPD), and who were 40 years and older were selected (n = 1145). Subjects who were willing to participate (n = 591) and who appeared to have an irreversible airway obstruction (n = 290) were included. To recruit controls, a random sample was taken of 676 individuals who were 40 years and older and who were not diagnosed as having asthma or COPD by their general practitioner. Of these 676 individuals 421 were willing to participate. The presence of diseases was determined by using a questionnaire. One hundred and ninety-four subjects (73%) and 229 controls (63%) were shown to be suffering from one or more (other) diseases. In both groups, locomotive diseases, high blood pressure, insomnia and heart disease were most common. Locomotive diseases, insomnia, sinusitis, migraine, depression, stomach or duodenal ulcers and cancer were significantly more common in the subject group than in the control group. For both clinical and research purposes, it is important to consider the presence of diseases in patients with a chronic airway obstruction.

In males, aging, health and disease are processes that occur over physiologic time and involve a cascade of hormonal, biochemical and physiological changes that accompany the down-regulation of the hypothalamic-anterior pituitary-testicular axis. As aging progresses there are relative increases of body fat and decreases in muscle mass. The increased adipose tissue mass is associated with the production of a number of newly generated factors. These include aromatase, leptin, PAI-1, insulin resistance, and the dyslipidemias, all of which can lead to tissue damage. Fatty tissue becomes the focal point for study as it represents the intersection between energy storage and mobilization. The increase in adipose tissue is associated with an increase in the enzyme aromatase that converts testosterone to estradiol and leads to diminished testosterone levels that favor the preferential deposition of visceral fat. As the total body fat mass increases, hormone resistance develops for leptin and insulin. Increasing leptin fails to prevent weight gain and the hypogonadal-obesity cycle ensues causing further visceral obesity and insulin resistance. The progressive insulin resistance leads to a high triglyceride-low HDL pattern of dyslipidemia and increased cardiovascular risk. All of these factors eventually contribute to the CHAOS Complex: coronary disease, hypertension, adult-onset diabetes mellitus, obesity and/or stroke as permanent changes unfold. Other consequences of the chronic hypogonadal state include osteopenia, extreme fatigue, depression, insomnia, loss of aggressiveness and erectile dysfunction all of which develop over variable periods of time.

Doping consists in the use of artificial means or substances with the unique aim of improving performance despite adverse effects on health. Amphetamines stimulate the central nervous system by increasing motivation and vigilance. Often consumed in association with analgesics, they increase the fatigue threshold during prolonged or repeated exercise. Addiction and dependency to these substances are extremely rapid. Side-effects include insomnia, exhaustion, violence and can lead to serious heart diseases. By enhancing capacity for intensive training, anabolic steroids improve strength, alertness and speed. This action is often further strengthened by the use of growth hormones DHEA and IGF-1. Extremely high dosage is used and is in no way comparable with natural secretions or those necessary to re-balance an exhausted glandular system. During prolonged endurance exercise, doping aims at improving the circulation of oxygen in the blood and thus its availability to the muscles. Firstly, the blood haemoglobin concentration was increased by blood transfusions. At present the production of red blood cells is stimulated by repeated injections of exogenous erythropoietin. The extreme viscosity of the blood leads to a risk of vascular thromboses and high blood pressure and accentuates greatly and sometimes even fatally the possibility of brachycardia which is common with sportsmen.

Past and current drug therapies for weight loss are discussed. More than 50% of Americans can be categorized as overweight or obese. Obesity is associated with increased mortality and with comorbidities such as hypertension, hyperglycemia, dyslipidemia, coronary artery disease, and certain cancers. According to guidelines for identification, evaluation, and treatment of obesity, patients with a body mass index (BMI) of > or = 30 kg/m2 should attempt to lose weight. Patients with a BMI of > or = 25 kg/m2 plus two or more risk factors or patients with an excessive waist circumference plus two or more risk factors should also attempt to lose weight. The initial goal is a 10% weight reduction in six months achieved through lifestyle changes. If lifestyle changes alone are not effective, then drug therapy may be indicated. Pharmacotherapeutic options for obesity have decreased over the past few years. Fenfluramine, dexfenfluramine, and phenylpropanolamine have been withdrawn because of severe adverse effects, leaving only sympathomimetics, sibutramine, and orlistat as anorectics with FDA-approved labeling. Phentermine has been shown to cause a 5-15% weight loss if given daily or intermittently. Compared with sibutramine and orlistat, phentermine is cheaper, and specific formulations allow once-daily administration. However, phentermine is indicated only for short-term treatment, and tolerance often develops. Common adverse effects associated with phentermine are dry mouth, insomnia, increased blood pressure, and constipation. Sibutramine increases norepinephrine and serotonin levels in the CNS and should not be taken with many antidepressants because of the risk of increased norepinephrine and serotonin levels. Its use is also contraindicated in patients with cardiovascular disease. Orlistat is not systemically absorbed; therefore, it does not cause the systemic adverse effects or drug interactions of phentermine and sibutramine. Orlistat has a cholesterol-lowering effect not seen with other diet medications. However, the three-times-daily administration and frequent gastrointestinal effects limit its use. Sibutramine, phentermine, and orlistat have both positive and negative properties. Choosing among the medications will depend on concurrent disease states and medications, ease of administration, and cost.

Well-known adverse effects of amisulpride include nausea, insomnia or tiredness, gastrointestinal, extrapyramidal and endocrine symptoms. Cardiac disorders, however, appear to be an extremely rare complication of the drug. Only a few case reports on this complication have been published so far, which deal with QT prolongation, hypotension, hypertension and palpitations. Bradycardia has not yet been mentioned. Here, we will report on a case of asymptomatic bradycardia that developed subsequent to therapeutic doses of amisulpride in a 25-year-old male patient with chronic paranoid-hallucinatory schizophrenia. The patient had been rehospitalized for an acute exacerbation of the psychosis. When the patient failed to respond at the beginning of hospitalization, the treatment was changed from clozapine to amisulpride. After a complete switchover to amisulpride, the patient's ECG showed sinus bradycardia and QT prolongation. When the daily dose of amisulpride was reduced from 800 mg/d to 600 mg/d, the patient's ECG quickly normalized (including blood pressure and pulse rate) within a few days. The patient did not report any cardiovascular-related complaints. Since the cardiovascular-specific diagnostics did not yield any indicative results, bradycardia may be a rare complication of amisulpride treatment.

(1) For smokers who want to quit and who qualify for pharmacological support, the various forms of nicotine replacement therapy available in France yield a one-year cessation rate of about 14-18%, compared to about 10% with placebo. (2) Amfebutamone (also known as bupropion) is structurally related to an amphetamine psychostimulant. (3) The clinical file mainly contains data from a dose-finding study, two placebo-controlled trials, and a trial comparing amfebutamone + transdermal nicotine with amfebutamone + transdermal placebo. (4) It has not yet been shown that the approved dose regimen of 300 mg/day is more effective than 150 mg/day, or that the treatment period of 7-9 weeks is optimal. (5) Compared to placebo, the one-year cessation rate was only about 13% higher (absolute value) in one trial, much less in the dose-finding study (3%), and not determined in the other two trials. The trial comparing amfebutamone with nicotine suffers from too many methodological weaknesses to show any difference in the efficacy of the two drugs. There has been no specific assessment of amfebutamone in patients with coronary heart disease. (6) There is no basis for combining amfebutamone with nicotine replacement therapy, as there is no evidence of higher efficacy. Furthermore, cardiovascular risk may be increased. (7) Amfebutamone can have serious adverse effects: the estimated risk is approximately 0.1% for convulsions and 3% for potentially severe hypersensitivity reactions. The adverse effects seem to be similar to those of appetite-suppressant amphetamines, including insomnia, weight loss and hypertension. The possible risk of heart valve disease has not been ruled out, because echocardiographic follow-up studies have not been done. (8) Potential adverse effects and drug interactions should contraindicate the use of amfebutamone by patients with a history of cardiovascular, neurological or psychiatric disorders. (9) In practice, when someone needs drug support to quit smoking, nicotine replacement therapy should be tried first.

Several theories, such as the 'homuncular reflex theory' 'delta reflex theory', and 'meridian theory' point to the fact that the ear is related to all parts of the human body and internal organs. Being one of the approaches in traditional Chinese medicine, auricular therapy is a therapeutic method by which specific points on the auricle are punctured or pressed. Auricular therapy can activate meridians and collaterals, regulate the Qi and blood, help to achieve the balance between Yin and Yang status of internal organs, and is therefore suitable for treating many disorders of the body. Successful examples of previous studies using this therapy including insomnia, weight reduction, hypertension, treatment of addiction, and pain reduction. However, inconsistency in the treatment protocol among studies, or the use of combined therapies, makes it impossible to draw a strong causal relationship between this therapy and the treatment effect. More appropriate clinical trials are therefore necessary to understand in depth the therapeutic effect of auricular therapy. Ideally, these trials can take place in the context of nursing practice so as to explore the application of this therapy in the realm of nursing, and to enable nurses to make a more effective contribution to primary health care.

The therapeutic use of methylphenidate for the management of attention-deficit hyperactivity disorder in children is increasing. As therapeutic use increases, the risk increases of unintentional overdoses, medication errors, and intentional overdoses caused by abuse, misuse, or suicide gestures and attempts. Side effects during therapy, which include nervousness, headache, insomnia, anorexia, and tachycardia, increase linearly with dose. Clinical manifestations of overdoses include agitation, hallucinations, psychosis, lethargy, seizures, tachycardia, dysrhythmias, hypertension, and hyperthermia. Methylphenidate tablets can be abused orally, or they can be crushed and the powder injected or snorted. Despite its abuse potential, there is disagreement regarding the extent to which methylphenidate is being diverted from legitimate use to abuse in preteens and adolescents.

The present study was conducted among 719 patients enrolled by 109 doctors to evaluate the efficacy and tolerability of the combination of losartan potassium and amlodipine besylate in Indian patients with mild to moderate hypertension. Out of them 11 patients were dropped out. Of these 708 patients 643 patients received once daily dosage of the combination whereas 10 patients received 1/2 daily, 13 patients received 1 1/2 daily and 42 patients received 1 twice daily dosage of the combination. The mean SBP in the study was 172.89 +/- 19.18 mm Hg baseline. After the 10-day treatment, the mean SBP had significant reduction ie, 13.1% from basal and at the end of day 20 of the treatment, the reduction was 19.13% from the baseline which was significant. Similarly mean DBP was 105.42 +/- 10.85 mm Hg at baseline. After treatment, the mean DBP had significant reduction. After 10- day treatment, there was 12.7% reduction from the baseline and at the end of the treatment ie, after day 20, the reduction was 17.70% from basal, which was significant. Global evaluation of efficacy was done by the physicians; 93.8% of the cases had excellent to good response and 4.9% patients had fair response. Details of any adverse event reported or noted during the treatment with the combination were recorded in the appropriate section of the case record form, whether considered treatment related or not, as reported by the patients. The severity of an adverse event was graded on a 3-point scale as mild, moderate and severe. The most common side-effects reported were oedema of feet (5.08%), ankle oedema (1.98%). Remaining adverse events included some cardiovascular events such as palpitations, gastro-intestinal events such as constipation, miscellaneous events, muscular pain, weakness, generalised swelling, etc. CNS events included giddiness, headache, insomnia, etc.

Exercise improves insulin resistance and has beneficial effects in preventing and treating type 2 diabetes. However, aerobic exercise is hindered in many type 2 diabetic patients because of advancing age, obesity, and other comorbid conditions. Weight lifting or progressive resistance training (PRT) offers a safe and effective exercise alternative for these people. PRT promotes favorable energy balance and reduced visceral fat deposition through enhanced basal metabolism and activity levels while counteracting age- and disease-related muscle wasting. PRT improves insulin sensitivity and glycemic control; increases muscle mass, strength, and endurance; and has positive effects on bone density, osteoarthritic symptoms, mobility impairment, self-efficacy, hypertension, and lipid profiles. PRT also alleviates symptoms of anxiety, depression, and insomnia in individuals with clinical depression and improves exercise tolerance in individuals with cardiac ischemic disease and congestive heart failure; all of these aspects are relevant to the care of diabetic elders. Moreover, PRT is safe and well accepted in many complex patient populations, including very frail elderly individuals and those with cardiovascular disease. The greater feasibility of using PRT over aerobic exercise in elderly obese type 2 diabetic individuals because of concomitant cardiovascular, arthritic, and other disease provides a solid rationale for investigating the global benefits of PRT in the management of diabetes.
