Fifty four women with repeated unsuccessful in vitro fertilization (IVF) cycles due to inadequate ovarian response to stimulation with human menopausal gonadotropins (hMG) participated in this study. They were randomized to receive either gonadotropin releasing hormone agonist (GNRHa), Buserelin, prior to and during induction of ovulation by hMG (Group I—long protocol), or GnRHa starting on the first day of the cycle together with induction of ovulation by hMG (Group II—short protocol). Mean follicular phase serum luteinizing hormone (LH) and progesterone (P) levels were significantly lower in Group I than in Group II (P<0.01). Cancellation rate was significantly lower in Group I than in Group II (P<0.01). The long GNRHa protocol resulted in statistically significant lower cancellation rates, more oocytes per pickup (OPU), more embryos trans-ferred per patient, and a higher pregnancy rate. Significantly more hMG ampoules and more treatments days were required in the long GNRHa protocol. Our data demonstrate that the use of GNRHa prior to and during ovarian stimulation with hMG offers a very good alternative for patients with repetitive unsuccessful IVF cycles due to inadequate response. 相似文献

A detrimental effect of transient elevation of plasma prolactin (PRL) during in vitro fertilization (IVF) has not been proven; however, treatment with a dopamine agonist has been suggested. The present study was undertaken to determine if transient, midcycle hyperprolactinemia exerted a deleterious effect on the number of oocytes retrieved or on fertilization of oocytes in vitro. Fifty-three infertile patients with midcycle hyperprolactinemia (PRL>20 g/liter) during ovarian hyperstimulation for IVF were compared with 53 matched controls who remained normoprolactinemic. Mean (±SE) serum PRL levels on the day after hCG were significantly higher in the study group (29.5±1 g/liter) than in the control (13.1±0.5 g/liter) (P<0.0005), whereas the mean estradiol (E2) concentrations on the same day were not significanily different (4822±287 and 4492±269 pmol/liters, respectively). Fertilization rates (72±4 and 70±4%, respectively) and the mean number of oocytes recovered (4.2±0.3 and 3.7±0.3, respectively) did not differ between the two groups. No correlation was observed between serum PRL and E2 levels, fertilization rates, or the number of oocytes retrieved in either group. Eleven patients with elevated PRL levels as a result of ovarian hyperstimulation were treated with 2.5 mg bromocriptine daily during the next IVF cycle. Serum PRL levels were significantly lower in the treated (5.6±1.8 g/liter) than in the untreated cycles (35.6±3.1 g/liter) (P<0.0005), whereas serum E2 concentrations did not differ. Although the mean number of oocytes recovered was significantly higher in the treated (6.2±1.1) than in the untreated (4.7±0.7) (P<0.02) cycles, the fertilization rates were significantly lower when the patients were treated with bromocriptine compared with the previous untreated cycle (55±8.0 and 76.5±7.0%, respectively;P<0.05). Our data demonstrate that a transient elevation of PRL during ovarian stimulation for IVF does not adversely affect the endocrine response, number of oocytes retrieved, or fertilization rates. No improvement in these parameters was observed in bromocriptine-treated cycles. These results do not support the treatment of transient hyperprolactinemia with dopamine agonists in IVF patients. 相似文献

Data from 443,812 admissions to publicly funded detoxification centers in Massachusetts (fiscal year 1984 to fiscal year 1996) were analyzed to assess changes in the population served. Substantial increases in admissions of women, African Americans, and Hispanics were apparent. Mean age at admission declined and unemployment increased. A 25% decline in admissions reporting alcohol use was coupled with a twofold increase in reported cocaine use and a fourfold increase in heroin use. Detoxification services have evolved. The older, white, male alcoholic is no longer the primary consumer. Policy initiatives (e.g., increased services for women) and the changing epidemiology of drug abuse (e.g., increased access to heroin) contributed to the changing population served in detoxification centers. 相似文献

A butyric acid pro-drug, pivaloyioxymethyl butyrate, AN-9, developed in our laboratory, was previously shown to act as a differentiation-inducing and an anti-cancer agent. In this study we have shown that both AN-9 and butyric acid caused a transient hyperacetylation of histones, which returned to basal levels after 6 and 12 hr, respectively. This activity precedes the induction of differentiation elicited by both agents. AN-9 induced acetylation of histones at a concentration one order of magnitude lower than butyric acid. Pre-treatment of the cells with esterase(s) inhibitors diminished the ability of AN-9 to inhibit proliferation and induce differentiation. The above suggests that the intracellular release of butyric acid fragment, from the pro-drug, is catalyzed by cellular esterase(s). 相似文献

OBJECTIVE. To determine if a question about symptoms of depression in a mail survey predicts mortality after adjusting for a large number of covariates. DESIGN. National cross-sectional survey of 141,589 enrollees in Medicare, age 65 and older. Analyses used multivariate logistic regression models with death as the outcome. RESULTS. Response to a question about sadness or anhedonia was associated with death in 2 years (OR = 1.32; 95% CI = 1.2, 1.4). Results were consistent across age, gender, and presence/absence of known heart disease. Other responses associated with death were older age, male gender, and self-reported cancers, shortness of breath, heart failure, smoking, and other characteristics. Higher education and being married appeared to protect from death. DISCUSSION. A single survey question about feelings of sadness or anhedonia is predictive of death in 2 years. 相似文献

Thalamic abnormalities have been hypothesized to explain much of the psychopathology in schizophrenia, however, quantitative magnetic resonance imaging (MRI) studies have yielded discrepant results as to whether there are thalamic volume alterations. The current study utilized high resolution MRI and an axial voluming protocol to determine if there was a significant reduction in the volume of the thalamus in patients with schizophrenia. Quantitative analysis was performed on magnetic resonance images of the brain in 41 male medicated schizophrenic patients and 39 male normal control subjects similar in age, education and handedness. There were no group differences in thalamic volumes between controls and patients with schizophrenia, even after adjusting for intracranial volume, total brain tissue volume, and gray matter volume. There were also no significant correlations between thalamic volume and either current neuroleptic dose or illness duration. However, there was a significant right greater than left thalamic volume asymmetry in schizophrenics and controls, and the degree of thalamic volume asymmetry was similar in both groups. The failure to detect any significant difference in thalamic volumes may be due to the heterogeneity of the schizophrenic population and as yet undetermined chronic effects of neuroleptic medication on the thalamus. However, another reasonable explanation for the study findings is that quantitative MRI voluming of the entire thalamus may not be sensitive enough to detect more subtle regional neuropathology within the thalamus. 相似文献

CMS has initiated the Nursing Home Quality Initiative (NHQI) to improve the quality of nursing home care. Central to the NHQI is the public reporting of nursing home quality measures that serve as the basis for the Initiative's communication and quality improvement program. This article provides an overview of the NHQI, focusing on the role of nursing home quality measures in achieving improvements in nursing home care. We also describe the evolution of quality measurement in nursing homes, a recent CMS project to improve measures through risk adjustment and other refinements, the use of these measures in a pilot of the NHQI, and the lessons learned for future work in this area. 相似文献

We summarize work done to identify and evaluate existing quality indicators (QIs) for long-term care (LTC) settings. Indicators operationally defined using routinely collected and computerized patient assessments were identified and then aggregated to characterize the performance of the nursing facility over a specific period of time. Of 143 indicators reviewed, only 22 were recommended for use in comparing performance across facilities. Conceptual and technical issues influence the appropriateness of QIs for different audiences. 相似文献

The steady increase in Eating Disorders (ED) during the last three decades has raised increasing concern over the early diagnosis and treatment of this disease. Due to the multi-factorial etiology of ED, treatment is complex, prolonged, and demands a team approach. Family physicians are often approached first for consultation following the patient's initial physical complaints. For this reason, the general practitioner can play a critical role in the early diagnosis and treatment of these disorders. By asking the appropriate questions and providing relevant information, the family physician (FP) may be able to refer the patient to treatment necessary for recovery, as well as assist in this process. Because the family physician typically has previous acquaintance with the patient and her family, he or she may be of considerable import to creating a therapeutic liaison and support framework with the professional team. This article will discuss the potential involvement and significance of the family physician in the successful diagnosis, prevention, and treatment of ED. The importance of the FP in the decision for hospitalization, referral, and follow-up is emphasized, as well as the pivotal role of the FP as a multi-disciplinary team coordinator. 相似文献
