Background. There is scant data on social and personal aspects related to the use of menopausal hormone therapy (HT) in Latin America.

Objectives. To obtain information regarding menopausal HT, i.e. use, perception, level and sources of knowledge, and to determine factors affecting several of these issues among middle-aged women of Guayaquil, Ecuador.

Design. A total of 349 women (nursing staff), aged 40 years or more, were included in the present cross-sectional study. Participants completed a structured questionnaire including details related to HT and the reasons for not using it, as well as demographic and psychosocial data.

Results. Only 50.1% of women considered HT beneficial. Current and former HT use was low (1.7% and 14.3%, respectively) and mean HT duration among former users was short (mean ± standard deviation: 1.0 ± 1.4 years). Women responded that the main reasons for not using HT were being asymptomatic (49.0%), non-established menopause (30.4%) and physician's advice (27.2%). Only 28.9% of women considered having enough information regarding HT, whereas a high percentage (93.1%) indicated willingness to participate in educational sessions addressing this issue. For most of the women the main sources of information were physicians, educational sessions and television. Logistic regression analysis determined that women with lower income and HT information did not consider HT beneficial at a higher rate than their counterparts. Premenopausal women and those with lower income were more prone to never HT use. Age and professional level were found to be confounding factors.

Conclusions. HT use in this population was low; hormonal status, economic income and level of HT information determined its use and benefit awareness.  相似文献

Objective.?To assess the female quality of life (QoL) during the menopausal transition and determine factors (personal and partner) related to its impairment. The frequency of menopausal symptoms was also assessed.

Methods.?In this cross-sectional study, healthy women aged 40–59 years were asked to fill out the Menopause Rating Scale (MRS) and a questionnaire assessing personal and partner demographic data.

Results.?During the study period, a total of 409 women were surveyed. Mean age was 47 ± 5.3 years (median 46). Mean educational level was 13.2 ± 4.1 years (median 14), with 28.1% having 12 or less years of schooling; premenopausal (42.1%), perimenopausal (24.4%) and postmenopausal (33.5%). At the time of the survey, 9.8% were receiving hormonal therapy (HT) for the menopause, 1.5% were on psychotropic drugs and 1.2% on alternative treatments for the menopausal. Regarding partner profile, 10.3% had erectile dysfunction, 11.2% had precocious ejaculation and 7.3% had abused alcohol. Mean total MRS score was 9.1 ± 6.4 (median 9); for the somatic subscale, 4 ± 2.7; the psychological subscale, 3 ± 2.8 and the urogenital subscale, 2.1 ± 2.5. Of the surveyed women, 50.6% presented a total MRS scoring of 9 or more (moderate to severe intensity). The four most frequently found symptoms of those composing the MRS were hot flushes (68.9%), sleeping problems (68.4%), depressive mood (55.2%) and irritability (51.6%). After adjusting for confounding factors, logistic regression analysis determined that female age, menopause and partner precocious ejaculation increased the risk for presenting higher total MRS scores (impaired female QoL) whereas HT use, church assistance and partner faithfulness decreased this risk.

Conclusions.?A high rate of middle-aged women in this series presented impaired QoL associated to female age and hormonal status and additionally to partner's health and sexual behavior.  相似文献

Magnetic resonance (MR) imaging with a whole-body imager was performed in 10 fresh, unfixed whole human brains selected randomly from cadavers. All subjects were neurologically intact before death. T2 time constants were measured within the caudate nucleus, putamen, globus pallidus, cortical gray matter, subcortical white matter, and optic radiation. These regions were then excised, and T2 values were measured again with a 1.5-T MR spectrometer. Quantitative assays of iron, ferritin, and protein from these areas were then performed. Iron concentration varied significantly among brain regions, whereas ferritin and protein concentrations were constant among brain regions and among individuals. Neither iron nor ferritin concentration showed any consistent correlation with T2 values. Histologic examination of brain micro-sections with iron- and ferritin-specific stains of demonstrated poor correlation with biochemical assays of ferritin and iron concentrations. Results indicate that T2 values correlate poorly with iron and ferritin concentrations found in neurologically intact brains.  相似文献

Arthrograms of the temporomandibular joint were obtained in 20 symptomatic joints that had previous reconstructive arthroplasty with disk repositioning because of internal derangements. Preoperative arthrograms were available for comparison in 18 joints. Symptoms resulting in a postoperative arthrogram included pain, limited ability to open the mouth, and clicking of the joints. Postoperative arthrographic findings included limited anterior translation of the condyle (90%), irregularity in outline of the intraarticular contrast agent (60%), a conical configuration of the posterior recess (25%), decreased size of the joint (28%), anterior displacement of the meniscus (25%), and perforated meniscus (15%). Many of these findings may have resulted from fibrosis and scarring, which may be a response to intraarticular bleeding. The mechanism by which the fibrosis causes the postsurgical arthrographic features is discussed.  相似文献

In a prospective, randomized, double-blind study, 49 patients underwent lumbar myelography using iotrol (24 patients) or metrizamide (25 patients). The diagnostic imaging adequacy of iotrol was comparable with that of metrizamide. After iotrol myelography, adverse reactions were fewer, less severe, and of shorter duration than were those following metrizamide myelography. Thirteen of 24 patients (54%) receiving iotrol reported some adverse reactions compared with 24 of 25 patients (96%) receiving metrizamide. Five moderate and one severe adverse reaction occurred in the group receiving iotrol. Fourteen moderate and eight severe adverse reactions occurred in the group receiving metrizamide. Thirty-eight patients underwent electroencephalography both before and after myelography (19 iotrol and 19 metrizamide). None of the EEGs obtained after iotrol myelography changed from baseline, while seven of the EEGs obtained after metrizamide myelography showed changes from baseline. Iotrol was judged superior to metrizamide as a contrast medium in this patient population.  相似文献

Objectives: To screen for potentially underreported behavioral changes in patients with idiopathic Parkinson's disease (PD) pre‐ and post‐deep brain stimulation (DBS), a retrospective data base review was performed. Methods: In total, 113 patients who underwent unilateral or bilateral DBS at the University of Florida in either subthalamic nucleus or globus pallidus internus for PD were screened for behavioral issues by asking about the presence or absence of seven neuropsychiatric symptoms (panic, fear, paranoia, anger, suicidal flashes, crying, and laughing). Results: There was a high prevalence of fear (16.3%), panic (14.0%), and anger (11.6%) at baseline in this cohort. In the first six months following DBS implantation, anger (32.6%), fear (26.7%), and uncontrollable crying (26.7%) were the most frequent symptoms reported. Those symptoms also were present following six months of DBS surgery (30.2%, 29.1%, and 19.8%, respectively). New uncontrollable crying occurred more in the acute postoperative stage (less than or equal to six months) (p= 0.033), while new anger occurred more in the chronic postoperative stage (greater than six months) (p= 0.017). The frequency of uncontrollable laughing significantly increased with bilateral DBS (p= 0.033). Conclusions: Many of the neuropsychiatric issues were identified at preoperative baseline and their overall occurrence was more than expected. There was a potential for worsening of these issues post‐DBS. There were subtle differences in time course, and in unilateral vs. bilateral implantations. Clinicians should be aware of these potential behavioral issues that may emerge following DBS therapy, and should consider including screening questions in preoperative and postoperative interviews. Standardized scales may miss the presence or absence of these clinically relevant issues.  相似文献

A phase I clinical trial was initiated to treat patients with stage IV B-derived chronic lymphocytic leukemia (CLL) with the IgG2a murine monoclonal antibody T101. This antibody binds to a 65,000-mol wt (T65) antigen found on normal T lymphocytes, malignant T lymphocytes, and B- derived CLL cells. All of the patients had a histologically confirmed diagnosis of advanced B-derived CLL and were refractory to standard therapy, and more than 50% of their leukemia cells reacted with the T101 antibody in vitro. The patients received T101 antibody two times per week, over two to 50 hours by intravenous administration in 100 mL of normal saline containing 5% human albumin. Twelve patients were treated with a fixed dosage of 1, 10, 50, or 100 mg, and one patient was treated with 140 mg of antibody. It was demonstrated that patients given two-hour infusions of 50 mg developed pulmonary toxicity, with shortness of breath and chest tightness. This toxicity was eliminated when infusions of 50 or 100 mg of T101 were prolonged to 50 hours. All dose levels caused a rapid but transient decrease in circulating leukemia cell counts. In vivo binding to circulating and bone marrow leukemia cells was demonstrated at all dose levels with increased binding at higher dosages. Antimurine antibody responses were not demonstrated in any patients at any time during treatment. Circulating free murine antibody was demonstrated in the serum of only the two patients treated with 100 mg of antibody as a 50-hour infusion and the patient treated with 140 mg of antibody over 30 hours. Antigenic modulation was demonstrated in patients treated at all dose levels but was particularly apparent in patients treated with prolonged infusions of 50 and 100 mg of antibody. We were also able to demonstrate antigenic modulation in lymph node cells, which strongly suggests in vivo labeling of these cells. Overall, T101 antibody alone appears to have a very limited therapeutic value for patients with CLL. The observations of in vivo labeling of tumor cells, antigenic modulation, antibody pharmacokinetics, toxicity, and antimurine antibody formation may be used in the future for more effective therapy when drugs or toxins are conjugated to the antibody.  相似文献
