Drugs, development, and cerebral function. Figure 1. Mesolimbic circuitry and the influence of CART peptide. High densities of CART-containing nerve terminals are found in the VTA, and many CART-containing cells and processes are found in the nucleus accumbens see text ; . Many of the nerve terminals in the VTA derive from a CART input from the lateral hypothalamus, which may play a role in integrating food and drug reward. CART in the VTA can influence DA neurons directly or indirectly through gamma amino butyric acid neurons. In the accumbens, DA nerve terminals are found on CART neurons GABAergic medium-spiny output neurons ; suggesting that DA influences CART. CART synapses in the accumbens from recurrent collaterals or other sources additionally suggest that CART can influence accumbal output, for instance, levonorgestrel and ethinyl estradiol.

In the developed world, the most serious squeals of preterm birth and highest risk of death occur in those preterm neonates born at less than 32 weeks. In the developing world, the morbidity and mortality associated with preterm birth are devastating even up to 36 weeks' gestation. Preterm birth is an epidemic characterized by disparity. Newborn health is one of the most striking examples of health inequality in the world. 98% of 3.9 million neonatal deaths each year occur in the poorest countries of the world 11 ; . Of those deaths, 50% are due to being born underweight, because of preterm delivery and or intrauterine growth restriction. Even in the developed world, the frequency and consequences of preterm birth are characterized by disparity. In the United States, African American women are nearly twice as likely to have a baby born preterm as Caucasian women. In fact, approximately 100, 000 African American newborns in the U.S. are affected each year by this common, costly and serious problem 9, 10 ; .

The menopause marks the end of menstruation and is due to cessation of ovarian hormone production. This can result from natural involution or surgical removal of the ovaries. The median age of natural menopause is 49 years although there is considerable variation. Prior to the final cessation of menses, there may be a peri-menopausal period of declining ovarian function when menstruation becomes less regular and symptoms of oestrogen deficiency more common. The major biochemical change at the menopause is a large fall in plasma oestradiol which is replaced as the main circulating oestrogen by oestone which is derived from adrenal androgens by peripheral conversion. This takes place in adipose tissue and oestrone levels are higher in obese women. Associated with the decline in oestrogen activity there is a rise in gonadotrophins, a raised FSH being the best biochemical marker of the menopause. Oestrogen deficiency has several effects on other tissues. There is atrophy of the genitalia and breasts. Calcium metabolism is also involved with an increase in bone resorption. This leads to a loss of bone at a rate of about 1% per year for the rest of life and with this an increased risk of fracture. Biochemically the changes in calcium metabolism are reflected in increased plasma and urinary calcium together with raised plasma alkaline phosphate and urinary hydroxyproline excretion. The major symptom of the menopause is the hot flush or sweat. These are very variable although there is a tendency to decline with age. The next most important symptoms relate to sexual function and include loss of libido, vaginal dryness and dyspareunia. Other symptoms are less specific and include changes in mental state and sleep pattern and muscle and joint pains. Oestrogen therapy leads to correction of the biochemical abnormalities and will usually relieve hot flushes. Relief of other symptoms is frequent but less predictable. Oestrogens will also reduce the rate of bone loss and with that the fracture rate. Such therapy is contraindicated in the presence of a history of thromboembolic disease, breast or gynaecological cancer, liver disease and severe varicose veins. In patients in which oestrogens are contraindicated, the progestogen norethisterone may be useful. Transdermal oestradiol 'patches' became available in 1987. Oestradiol given this way avoids the 'first-pass' effect on the liver and thus does not affect the liver enzymes which may be implicted in clotting and hypertension.

All methods of assessment showed a statistically significant improvement on the LA-treated half of the face. Laser profilometry, the most objective method used, showed an average decrease in skin roughness of 50.8% on the LA-treated side, compared with 40.7% for placebo. The authors concluded that 12 weeks of treatment with a cream containing 5% LA improves clinical characteristics related to photoaging of facial skin. Clin Exp Dermatol. 2001 Oct; 26 7 ; : 578-82 Br J Dermatol. 2003 Oct; 149 4 ; : 841-9 Vitamin C and E Studies have shown that antioxidants can be delivered percutaneously to directly supplement the skin's antioxidant reservoir and provide protection from untraviolet radiation. Oral supplementation has not been successful in raising levels of antioxidants in the skin. ; Topical vitamin C, when properly formulated, effectively penetrates the skin and can produce a 20-fold increase in endogenous levels of cutaneous vitamin C. At the North Carolina Biotechnology Center, Raleigh, Darr et al. reported that, in swine skin, vitamin C is capable of additive protection against acute UVB damage when combined with a UVB sunscreen. A combination of both vitamins E and C provided very good protection from UVB radiation with the bulk of the protection attributable to vitamin E. However, vitamin C was significantly better than vitamin E at protecting against UVA-mediated phototoxic insult. When vitamin C or a combination of vitamin C and E is formulated with a commercial UVA sunscreen oxybenzone ; , an apparently greater than additive protection is noted against the phototoxic damage. These results confirm the utility of antioxidants as photoprotectants and suggest the importance of combining the antioxidants with known sunscreens to maximize photoprotection. Acta Derm Venereol. 1996 Jul; 76 4 ; : 264-8 Estrogen Therapy to Prevent or Reverse Skin Aging Declining estrogen levels are associated with a variety of cutaneous changes, many of which can be reversed or improved by topical or systemic estrogen supplementation. Studies of postmenopausal women indicate that estrogen deprivation is associated with declining dermal collagen content, diminished elasticity and skin strength, loss of moisture in the skin, epidermal thinning, atrophy, fine wrinkling, and impaired wound healing. Low estrogen levels exacerbate the deleterious effects of both intrinsic and environmental aging. The therapeutic effects of topical application of 0.01% estradiol and 0.3% estriol compounds were compared in 59 perimenopausal women with skin aging symptoms. After treatment for 6 months, elasticity and firmness of the skin had markedly improved and wrinkle depth and pore sizes had decreased by 61 to 100% in both groups. Systemic estrogen levels did not increase and no systemic hormonal side effects were noted.

GPs need support and learning methods to manage their own and their patients' bereavement. BMJ July 31, 1999; 319: USE OF ALTERNATIVE MEDICINE BY WOMEN WITH EARLY-STAGE BREAST CANCER Among women with newly diagnosed early-stage breast cancer who had been treated with standard therapies, new-use of alternative medicine was a marker of greater psychosocial distress and worse quality of life. NEJM June 3, 1999; 340: PREDICTED IMPACT OF INTRAVENOUS THROMBOLYSIS ON PROGNOSIS OF GENERAL POPULATION OF STROKE PATIENTS: Simulation Model "Treatment with alteplace may benefit single patients but will have no impact on the general prognosis of stroke." Alteplace therapy requires a specialist setting. It would require large investments and reorganization of the care of stroke patients. This marginally effective treatment, which is also potentially harmful, requires more study before being widely offered.

Much of the data came from women who used conjugated equine estrogens or estradiol, often given with a progestagen. Users tend to be healthier, better educated, more physically active, leaner, and to more often drink moderate amounts of alcohol than other women in the same region. Thus, data must be interpreted with caution. Bias probably influences results of studies.

Lung cancer is the most common cancer in the world. It is a highly lethal disease in women and men, and new treatments are urgently needed. Previous studies implicated a role of estrogens and estrogen receptors in lung cancer progression, and this steroidal growth-stimulatory pathway may be promoted by tumor expression and activity of aromatase, an estrogen synthase. We found expression of aromatase transcripts and protein in human nonsmall cell lung cancer NSCLC ; cells using reverse transcription-PCR and Western immunoblots, respectively. Aromatase staining by immunohistochemistry was detected in 86% of archival NSCLC tumor specimens from the clinic. Further, biological activity of aromatase was determined in NSCLC tumors using radiolabeled substrate assays as well as measure of estradiol product using ELISA. Significant activity of aromatase occurred in human NSCLC tumors, with enhanced levels in tumor cells compared with that in nearby normal cells. Lung tumor aromatase activity was inhibited by anastrozole, an aromatase inhibitor, and treatment of tumor cells in vitro with anastrozole led to significant suppression of tumor cell growth. Similarly, among ovariectomized nude mice with A549 lung tumor xenografts, administration of anastrozole by p.o. gavage for 21 days elicited pronounced inhibition of tumor growth in vivo. These findings show that aromatase is present and biologically active in human NSCLCs and that tumor growth can be down-regulated by specific inhibition of aromatase. This work may lead to development of new treatment options for patients afflicted with NSCLC. Cancer Res 2005; 65 24 ; : 11287-91.
