Levonorgestrel-releasing implants are long acting contraceptives, approved for 5 years of continuous use. Two marketed systems, the six capsule Norplant use of tradenames is for product identification purposes only and does not imply endorsement. and the two rod Jadelle, have essentially equal rates of drug release, pregnancy and adverse events over 5 years of use. Randomised clinical trials and controlled cohort observations indicate that for the first 3 years, when pregnancy rates are at or almost zero, no other contraceptive system is more effective, although etonogestrel implants provide equal effectiveness. Annual pregnancy rates rise in the fifth year of continuous use but remain below 1 per 100 women. Annual pregnancy rates of Norplant users remain below 1 per 100 throughout 7 years of continuous use. Levonorgestrel implants provide low progestogen doses; 40-50 microg/day at 1 year of use, decreasing to 25-30 microg/day in the fifth year. Serum levels of levonorgestrel at 5 years are 60-65% of those levels measured at 1 month of use. Adverse effects with levonorgestrel implants are similar to those observed with progestogen only and combined oral contraceptives. Risks of ectopic pregnancy, other pregnancy complications and pelvic inflammatory disease are reduced in comparison with those of women using copper or non-medicated intrauterine devices. Risks of developing gallbladder disease and hypertension or borderline hypertension, although small, are about 1.5 and 1.8 times greater, respectively, in women using levonorgestrel implants than in women not using hormonal contraception. Other serious diseases have not been found to occur significantly more frequently in levonorgestrel implant users than in women not using hormonal contraception. The great majority of levonorgestrel implant users experience menstrual problems, but serious bleeding problems are not more frequent than in controls. Other health problems reported more frequently by levonogestrel implant users than by women not using hormonal contraception in a study of 16000 women included skin conditions, headache, upper limb neuropathies, dizziness, nervousness, malaise, minor visual disturbances, respiratory conditions, arthropathies, weight change, anxiety and non-clinical depression. Clinical depression is not more frequent in women using implants compared with those not using hormonal contraception (i.e. using intrauterine devices, sterilisation). Removal problems occur less frequently with Jadelle than with Norplant. The mean removal time for Jadelle is half that of Norplant. Levonorgestrel implants in nationally representative scientific samples, in randomised trials, and in controlled cohort studies have continuation rates as high as or higher than any other reversible contraceptive over a duration of 5 years. This would imply that the satisfaction women derive from the contraceptive effectiveness of levonorgestrel implants greatly outweighs the dissatisfaction that may accompany menstrual disturbances and other adverse effects associated with implants.

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.

Relationships between depression, alcohol and illicit drug use, adherence behaviors, and blood pressure (BP) were examined in 190 urban hypertensive Black men enrolled in an ongoing hypertension control clinical trial. More than one fourth (27.4%) of the sample scored greater than 16 on the Center for Epidemiological Studies-Depression Scale (CES-D), indicating a high risk of clinical depression. Depression was significantly associated with an increased likelihood of meeting Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for alcohol abuse or dependence (odds ratio = 5.2; 95% confidence interval = 1.897-14.214). The level of depression was significantly correlated with poor medication (r =.301) and poor dietary compliance (r =.164). Both alcohol intake and illicit drug use were significantly correlated with poor dietary compliance (r =.195 and.185, respectively) and smoking (r =.190 and.269, respectively). Although no direct relationship between depression and the level of BP was substantiated by multivariate analysis, findings of descriptive analyses revealed statistically significant associations among depression, substance use, poor adherence, and poor BP outcomes. Given the harsh environment in which a large number of young urban Black men live, the high prevalence of substance abuse might be an attempt to fight off depression. Further in-depth investigation is needed to identify the role of depression and BP control in urban young Blacks in order to construct effective interventions that address their unique needs.

To assess the effect of health education on blood pressure control and depression symptoms, we conducted a prospective study in 272 patients with essential hypertension. Depression symptoms were assessed by the Zung Self-rating Depression Scale (SDS). There was no significant difference in the level of hypertension and SDS scores between the educational (n = 138) and control (n = 134) group before the study (p > 0.05). After 12 months of follow-up, the body mass index (BMI) was reduced in the educational group (23.6 +/- 2.6 vs 21.4 +/- 2.2 kg/m2, p < 0.01), but it remained unchanged in the control group. The average systolic and diastolic blood pressure were reduced in both groups, but the amplitude of systolic blood pressure reduction in the educational group was greater than that of the control group (7.9 +/- 2.3 vs 4.2 +/- 2.0 mmHg, p < 0.01). The incidence of depression (10.9% vs 10.4%) and the average SDS scores (32.4 +/- 6.7 vs 33.2 +/- 6.9) were similar between the two groups (p > 0.05). However, in the depressed patients who received hypertension education, the average systolic (160.2 +/- 12.4 mmHg) and diastolic (89.8 +/- 7.3 mmHg) blood pressure was significantly lower than that of the control group (169.1 +/- 16.8 and 96.8 +/- 13.0 mmHg, respectively, p < 0.01). We conclude that hypertension education does not reduce the incidence or symptoms of depression, but it may facilitate blood pressure management in patients with clinical depression.

A large-scale national representative community survey of 11,122 persons aged more than 35 years included the investigation of the coincidence of depressive symptoms, vital exhaustion, cardiovascular disorders, stroke, and myocardial infarction. A total of 20.3% of the survey participants reported having experienced a cardiovascular disorder (CVD). Of the subjects reporting a CVD, 52.1% exhibited depressive symptoms (22.0% subthreshold depressive symptoms, 30.1% clinical depression), and 69.7% exhibited vital exhaustion. The authors investigated 3 cardiovascular subgroups: (1) subjects having experienced a myocardial infarction (MI), (2) subjects having experienced stroke, and (3) subjects with a CVD but no experience of either an MI or a stroke. The frequency and severity of depressive symptoms did not differ significantly in the 3 subgroups. CVD subjects with no MI or stroke had almost as high frequencies of depressive symptoms and vital exhaustion as patients who experienced stroke or MI. The strength of relationships between these psychological variables and CVDs do not differ significantly from the relationships between hypertension or diabetes and CVDs. Depressive symptoms and increased vital exhaustion have exceptionally high comorbidity with CVDs. The authors detected the same high comorbidity among patients with a milder CVD and without stroke or MI. The assessment and management of depressive symptoms and vital exhaustion should be routine procedure in clinical cardiology.

In only recent history, illicit use of methamphetamine, once isolated to urban areas on the West Coast, has spread into rural areas of the Midwest and southern United States. Although past and current methamphetamine legislation has increased penalties for methamphetamine manufacturers and tightened restrictions on sales of known precursors, the problem still persists. In fact, a 2004 survey indicates that an alarming 6.2% of high school seniors have tried methamphetamine. A number of biological, genetic, and environmental factors influence children's and adolescents' paths to substance abuse. Nurses should recognize the symptoms of methamphetamine abuse, which include agitation; aggressive behavior; rapid mood swings; hypertension; tachycardia; and eventually lesion-marked skin, clinical depression, and paranoid psychosis. Treatment for methamphetamine addiction includes behavioral therapy. Research on pharmacologic therapy is lacking. Educating youth on methamphetamine prevention appears to be the best approach to curb the spreading use of this addictive and deadly drug.

This study examined the prevalence of major and minor depression in patients with acute coronary syndrome and their relation with heart rate and heart-rate variability, and clinical characteristics. The study group included 297 patients, 200 men and 97 women, between ages of 21 and 70 years (M age = 57.5 +/- 9.6), who were admitted to a coronary care unit with acute coronary syndrome and survived to discharge from the hospital. Major and minor depression were diagnosed using DSM-IV. There were 44.1% patients with acute coronary syndrome without depression, 29.3% with minor depression, and 26.6% with major depression. The prevalence of minor and major depression was more elevated in patients with non-ST-segment elevation myocardial infarction and unstable angina than in patients with ST-segment elevation myocardial infarction. Ventricular fibrillation and atrial fibrillation were more common in patients with major and minor depression than in patients without depression. The 24-hr. duration of heart-beat intervals and heart-rate variability were significantly lower in patients with major and minor depression than in patients without depression. This study implies that clinical depression was significantly comorbid with the acute coronary syndrome and was related to hypertension, diabetes mellitus, age, sex, type of acute coronary syndrome, left ventricular failure, higher heart rate, and lower heart-rate variability.

Psoriasis-the most prevalent autoimmune disease in the United States-is a chronic, relapsing disease with variable clinical features and triggers that are both genetic and environmental. Psoriasis is an independent risk factor for mortality and is linked to numerous comorbidities, including cardiovascular disease, clinical depression, diabetes, cancer, Crohn's disease, hypertension, obesity, metabolic syndrome, liver disease, infections, dyslipidemia, and osteoporosis. While there is no cure, topical medications, phototherapy, traditional systemic agents, and biologics offer a wide array of options for management of symptoms. A combination of agents is frequently needed for moderate-to-severe cases, and positive long-term outcomes require medication adherence. Significant knowledge gaps exist on disease onset and progression along with a lack of comparative-effectiveness research on treatment regimens.

The hippocampus is particularly vulnerable to the neurotoxic effects of obesity, diabetes mellitus, hypertension, hypoxic brain injury, obstructive sleep apnoea, bipolar disorder, clinical depression and head trauma. Patients with these conditions often have smaller hippocampi and experience a greater degree of cognitive decline than individuals without these comorbidities. Moreover, hippocampal atrophy is an established indicator for conversion from the normal ageing process to developing mild cognitive impairment and dementia. As such, an important aim is to ascertain which modifiable factors can have a positive effect on the size of the hippocampus throughout life. Observational studies and preliminary clinical trials have raised the possibility that physical exercise, cognitive stimulation and treatment of general medical conditions can reverse age-related atrophy in the hippocampus, or even expand its size. An emerging concept--the dynamic polygon hypothesis--suggests that treatment of modifiable risk factors can increase the volume or prevent atrophy of the hippocampus. According to this hypothesis, a multidisciplinary approach, which involves strategies to both reduce neurotoxicity and increase neurogenesis, is likely to be successful in delaying the onset of cognitive impairment with ageing. Further research on the constellation of interventions that could be most effective is needed before recommendations can be made for implementing preventive and therapeutic strategies.

The aim of this study is to examine the association between symptoms of depression and anxiety and hypertension status. Participants (n=455, 238 women) were drawn from the Dutch Famine Birth Cohort Study. In 2002-2004, they attended a clinic assessment during which socio-demographics, anthropometrics, resting systolic blood pressure (SBP) and health behaviours were measured. Symptoms of depression and anxiety were measured using the Hospital Anxiety and Depression Scale. In 2008-2009, participants completed a questionnaire, which asked whether they ever had a physician diagnosing them as suffering from hypertension. In separate regression models that initially adjusted for age and then additionally for sex, socio-economic status, smoking, sports participation, alcohol consumption, resting SBP, antidepressive and anxiolytic medication, whether or not participants were exposed to the Dutch famine in utero, BMI and waist:hip ratio, both depression and anxiety were positively associated with hypertension status. Those who met the criterion for possible clinical depression and anxiety were also more likely to be hypertensive, and these associations remained statistically significant in the fully adjusted regression model. In conclusion, symptoms of depression and anxiety were associated with a diagnosis of hypertension assessed 5 years later, although the mechanisms underlying these associations remain to be determined.
