Coordinated efforts to identify susceptibility genes for unipolar major depressive disorder (MDD) and related disorders are now underway. These studies have focused on recurrent, early-onset MDD (RE-MDD), the most heritable form of this disorder. The goal of this study was to characterize the burden of MDD and other mood disorders, comorbid mental disorders, and excess mortality in RE-MDD families. A total of 81 families were identified through probands over the age of 18, who met criteria for recurrent (> or = 2 episodes), early-onset (< or = 25 years), nonpsychotic, unipolar MDD (RE-MDD), and included 407 first-degree relatives and 835 extended relatives. Psychiatric diagnoses for probands and their family members who provided blood samples were formulated from structured personal interviews, structured family history assessments, and available medical records. The remaining family members who participated and those who were deceased were evaluated through the family history method augmented by available medical records. Best estimate diagnoses were made during a consensus conference according to established diagnostic criteria. Approximately half of the first-degree relatives and a quarter of extended relatives of RE-MDD probands suffered from at least one mood disorder, typically MDD. As commonly observed for other oligogenic, multifactorial disorders, the severity of MDD reflected by age at onset and number of episodes attenuated with increasing familial/genetic distance from the proband. A substantial fraction of RE-MDD probands and their first-degree relatives met diagnostic criteria for additional psychiatric disorders that include prominent disturbances of mood. The deceased relatives of RE-MDD probands died at a median age that was 8 years earlier than for the local population; over 40% died before reaching age 65. These differences in mortality statistics resulted from a shift toward younger ages at death across the lifespan, including a fivefold increase in the proportion of individuals who died in the first year of life. Several-fold increases in the proportion of deaths by suicide, homicide, and liver disease were observed among the relatives of RE-MDD probands. However, the rank order of the three most common causes of death-heart disease, cancer, and stroke-remained unchanged and differences in the proportions of deaths from the remaining causes were small. RE-MDD is a strongly familial condition with a high rate of psychiatric comorbidity, whose malignant effects have a significant negative impact on the health and longevity of patients and their family members.

Partial correction of anemia in patients with chronic kidney disease (CKD) improves anemia-related symptoms. However, controversy remains as to whether total correction of anemia provides benefits over and above those afforded by partial correction. There is some evidence showing that normalization of hemoglobin (Hb) concentrations may improve the cardiac hyperdynamic state in CKD patients and reduce the diameter of the left ventricle. Further studies have shown that normalization of Hb improves cognitive function and physical capacities as measured by quality of life (QoL) tests. Large studies have shown that in dialysis patients there is a close inverse relationship between hematocrit (Hct) levels and mortality and morbidity. Moreover, there is evidence suggesting that Hct levels higher than those recommended by European Best Practice Guidelines (EBPG) and the National Kidney Foundation Dialysis Outcome and Quality Initiative (NKF-DOQI provide better outcomes for patients with CKD. However, when Hb concentrations are increased to normal in selected patients with cardiac disease, congestive heart failure, or ischemic cardiopathy, higher mortality rates are evident. Therefore, while the majority of patients with CKD may experience significant benefits when Hb is normalized, it seems prudent to recommend individualized target Hb concentrations for each patient, taking into account factors such as age, sex, employment status, physical activity, and co-morbidities.

Low back pain (LBP) poses an economic burden to society, mainly in terms of the large number of work days lost by a small percentage of patients who develop chronic LBP. The object of this review is to gain a better understanding of the societal costs of LBP and to see whether current clinical management follows evidence-based guidelines and is economically attractive, by reviewing studies on LBP with economic implications. To this end, the Medline database was searched between 1996 and 2001 using appropriate keywords, broadly defined. A total of 372 abstracts were screened and paper copies of 73 potentially relevant articles were obtained. It was found that the cost of LBP illness was high and was comparable to other disorders such as headache, heart disease, depression or diabetes, but actual cost estimates varied depending on the costing methodology employed. A small percentage of patients with chronic LBP accounts for a large fraction of the costs. Excessive and inappropriate use of diagnostic or therapeutic services can be documented but varied by region and provider type. Management according to evidence-based guidelines was not necessarily economically attractive. Interventions for acute or chronic LBP failed to show economic benefits, but demonstrated modest clinical benefits, which suggested a weak relationship between clinical and economic outcomes. The conclusion was that common definitions and costing methodologies need to be found to gain a better understanding of the true costs to society and to make studies comparable. A better definition is needed for the type for patient with LBP for whom therapeutic management is most likely to have a long-lasting economic benefit.

Cardiovascular disease (CVD), and in particular coronary artery heart disease (CAHD), is the leading cause of morbidity and mortality in women. Until recently, most of our knowledge about the pathophysiology of CVD in women - and, subsequently, management guidelines - were based on studies conducted mostly in men. While similar mechanisms operate to induce CVD in women and men, gender-related differences exist in the anatomy and physiology of the myocardium, and sex hormones modify the course of disease in women. Women, more than men, have their initial manifestation of CAHD as angina pectoris; are likely to be referred for diagnostic tests at a more advanced stage of disease, and are less likely than men to have corrective invasive procedures. The overall morbidity and mortality following the initial ischaemic heart event is worse in women, and the case fatality rate is greater in women than in men. Also, the relative impact of impaired vasoreactivity of the coronary artery, increased viscosity of the blood and dysregulation of automaticity and arrhythmia, is greater in women than in men. The most effective means of decreasing the impact of CVD on women's health is by an active approach from childhood to proper principles of healthcare in order to modify the contribution of specific risk factors. The latter include obesity, abnormal plasma lipid profile, hypertension, diabetes mellitus, cigarette smoking, sedentary lifestyle, increased blood viscosity, augmented platelet aggregability, stress and autonomic imbalance. The use of lipid-lowering drugs has not been adequately studied in women but reports from studies conducted mostly in men do predict an advantage also to women. Oestrogen deficiency after spontaneous or medically induced menopause is an important risk factor for CVD and CAHD. Observational and mechanistic data suggest a role for oestrogen replacement after menopause for primary, and possibly secondary, prevention of CVD. However, two recent prospective trials suggest that treatment de novo with hormone replacement of older post-menopausal women after an acute coronary event may not confer cardiovascular protection and may increase the risk of thromboembolic disease. Results of ongoing long-term studies may determine the beneficial role of hormone replacement versus potential risks involved with this treatment.

Hormone replacement therapy has traditionally been used to treat the accompanying symptoms of oestrogen deficiency in menopause. However, not all women can, or prefer to, receive this treatment and alternatives should be considered to reduce the increased risk of osteoporosis and heart disease in menopausal women. This chapter reviews the current literature on the efficacy of phyto-oestrogens in preventing cardiovascular disease, various cancers and osteoporosis, as well as treating the vasomotor and other menopause-related symptoms. Select herbal therapies, as well as selective oestrogen receptor modulators, are also considered.

Tomato is an important player in the agricultural market. It is the second most consumed vegetable in the world and is a source of important micronutrients such as lycopene and beta-carotene. Recent research has demonstrated that these carotenoids can act as free-radical quenchers in the body and prevent aging, tissue damage, heart disease, and certain cancers. Besides these microcomponents, tomato is composed of soluble and insoluble solids. In industry, these solids govern factory yield and play a major role in the tomato trade. Nowadays, standard methods for determining tomato solids and carotenoids are time and labor consuming. In this work, we present the development of a simultaneous and nondestructive method for determining total and soluble solids, as well as lycopene and beta-carotene, in tomato products by near-infrared spectroscopy. PLS-1 was the calibration technique chosen. For spectra preprocessing, MSC and second derivative were applied. As variable selection techniques, the correlogram cutoff, the successive projections algorithm, the dimension wise selection, and spectra splitting approach were applied. Best models presented satisfactory prediction abilities evaluated through its RMSEP and r values: total solids 0.4157, 0.9998; soluble solids 0.6333, 0.9996; lycopene 21.5779, 0.9996; beta-carotene 0.7296, 0.9981.

(Neuro-)endocrine tumours of the gastrointestinal tract are also called 'carcinoids'. (Neuro-)endocrine midgut tumours can be categorized according to their clinical behaviour. Most tumours are non-functioning. Functioning tumours are responsible for the carcinoid syndrome. The carcinoid syndrome is almost uniquely associated with midgut carcinoids. Symptoms of the carcinoid syndrome are caused by an excess of biogenic amines, peptides and other factors in the circulation. The typical symptoms of the carcinoid syndrome are diarrhoea, flushing, and carcinoid heart disease. Carcinoid heart disease involves the tricuspid and pulmonary valves and the endocardium. Serum chromogranin A and urinary excretion of 5-hydroxy-indoleacetic acid (5-HIAA) are biochemical markers. Carcinoid tumours express large numbers of high-affinity somatostatin receptors. These can bind the currently available octapeptide somatostatin analogues. In inoperable patients, biotherapy with somatostatin analogues and interferon-alpha is the treatment of choice. Somatostatin analogues and interferon-alpha significantly improve symptoms.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility in United States, affecting 6-10% of females in the reproductive age group. Recent studies have shown that insulin resistance plays an important role in the pathogenesis of PCOS. Traditionally, management of PCOS consisted mainly of ovulation induction, treatment of acne and hirsutism, and prevention of endometrial cancer. However, with mounting evidence showing that PCOS is associated with dysmetabolic syndrome and an increased risk for developing diabetes and heart disease, this can no longer be our sole focus. Current data support a strong recommendation that women with PCOS should undergo comprehensive evaluation for diabetes and recognized cardiovascular risk factors and receive appropriate treatment as needed. Lifestyle modifications remain the first-line therapy for all obese women with PCOS. However, many obese women with PCOS find weight loss difficult to achieve and maintain, and this is not an option for lean women with PCOS. For these reasons, insulin-sensitizing drugs are proving to be a promising and unique therapeutic option for chronic treatment of PCOS.

Matrix metalloproteinases (MMPs) have been shown to play significant roles in a number of physiological as well as pathological processes. Best known to proteolyse components of the extracellular matrix, MMPs have recently been discovered to also target a growing list of proteins apart from these, both inside and outside the cell. MMPs have also been traditionally thought of as enzymes involved in chronic processes such as angiogenesis, remodelling and atherosclerosis on a days-week time-scale. However they are now understood to also act acutely in response to oxidative stress on a minutes time-scale on non-extracellular matrix substrates. This review focuses on the acute actions and both extracellular and intracellular targets of two prominent MMP family members, MMP-2 and -9, in cardiovascular diseases including ischaemia/reperfusion injury, inflammatory heart disease, septic shock and pre-eclampsia. Also discussed are various ways of regulating MMP activity, including post-translational mechanisms, the endogenous tissue inhibitors of metalloproteinases and pharmacological inhibitors. A comprehensive understanding of MMP biology is necessary for the development of novel pharmacological therapies to combat the impact of cardiovascular disease.

Depression is underrecognized in older adults, especially those with chronic conditions such as heart disease and arthritis. Left untreated, depression may progress and have dramatic effects on overall health. The Geriatric Depression Scale: Short Form is a 15-question screening tool for depression in older adults that takes five to seven minutes to complete and can be filled out by the patient or administered by a provider with minimal training in its use. The questions focus on mood; the score can help clinicians decide whether further assessment is needed. (This screening tool is included in a series, Try This: Best Practices in Nursing Care to Older Adults, from the Hartford Institute for Geriatric Nursing at New York University's College of Nursing.)
