Patients who have had an organ transplant have a need for highly effective contraception. Intrauterine devices, depo-medroxyprogesterone acetate, and implantable etonorgestrel have the highest efficacy combined with the least chance of interaction with antirejection medication regimens. Combined hormonal contraceptives and progestin-only pills are also acceptable methods for patients who do not have other contraindications to their use. Barrier method use should be advocated for any patient who is entering a new sexual relationship and as an adjunct to other methods. Consultation with a gynecologist experienced with the provision of contraceptives to medically complicated patients is advised for all women of reproductive age who have received an organ transplant.  相似文献

BackgroundRecent evidence has demonstrated that athletes are at greater risk for a lower extremity injury following a return-to-sport (RTS) after sport-related concussion (SRC). The reason for this is not completely clear, but it has been hypothesized that persistent deficits in neurocognitive factors may be a contributing factor.Hypothesis/PurposeThis study assessed simple reaction time, processing speed, attention, and concentration in a group of athletes, post-concussion upon clearance for RTS for potential deficits that may result in slower reaction time, processing speed, attention, and concentration. The researchers hypothesized that the concussion group would demonstrate worse scores on both assessments compared to a sex-, age-, and sport-matched cohort.Study DesignCase-controlled studyMethodsTwelve participants who had suffered a SRC and eight healthy individuals who were matched to the concussed group by age, sex, and sport were evaluated. Those with a concussion had been cleared for RTS by a licensed healthcare provider. Each participant underwent neurocognitive tests that included a simple reaction time test (SRT) and the King-Devick Test (K-D). Independent t-tests were performed to compare the groups with significance set a priori at p<0.05.ResultsThere was a significant difference (p =0.024) between groups for SRT with the concussed group demonstrating a better SRT than the control group. There were no significant differences (p =0.939) between the groups for the K-D.ConclusionWith no significant differences between groups in the K-D assessment and, surprisingly, the concussed group having a better SRT compared to the healthy group, our hypothesis was not supported.Clinical RelevanceThese specific measures, compounded with extensive post-concussion time lapse until RTS clearance, may have limited capacity in revealing potential persistent deficits in relevant neurocognitive characteristics.Level of EvidenceLevel of Evidence 3  相似文献

A patient with systemic lupus erythematosus developed an acute surgical abdomen secondary to spontaneous rupture of the liver and died. Postmortem examination revealed an arteritis of the liver, pancreas, adrenal gland, skeletal muscle, and spleen. It appeared that an arteritis of the liver produced areas of infarction that ruptured and caused the clinical findings.  相似文献

Data regarding convenient, valid methods for measuring U.S. isoflavone intake are limited. We evaluated a soy food questionnaire (SFQ), the Willett food frequency questionnaire (FFQ), and overnight urine samples relative to excretion in 24-h urine samples. We also described intake among women in a high-risk program for breast or ovarian cancer. Between April 2002 and June 2003, 451 women aged 30 to 50 yr with a family history of breast or ovarian cancer completed the SFQ and FFQ. Of them, 27 provided four 24-h and overnight urine specimens. In these women, 24-h sample measures were correlated with SFQ estimates of daidzein (Spearman r = .48) and genistein (r = .54) intake, moderately correlated with the Willett FFQ (daidzein r = .38, genistein r = .33), and strongly correlated with overnight urine excretion (daidzein r = .84, genistein r = 0.93). Among all 451 SFQ respondents, mean (median) daidzein and genistein intakes were 2.8 (0.24) and 3.9 (0.30) mg/day. Primary sources of both were soymilk, soy nuts, and tofu. We conclude that targeted soy food questionnaires, comprehensive FFQs, and multiple overnight urines are all reasonable options for assessing isoflavone intake in epidemiologic studies.  相似文献

The health industry may be the prototype for changing gender roles among managers. Already women dominate mid‐level management positions. Meager data exist on senior health executives. In this exploratory study we examine the professional experiences of nationally prominent women leaders in Washington, D.C., who have recently been at the forefront of changing national health policy. Their career development, management styles, and influence in national health policy are discussed and analyzed. The leadership style of these women differs from the traditional male style, and they experienced role conflicts in their rise to power. The women in this study may be foreshadowing the roles of new leaders in the health industry in the 1990s.  相似文献
