AHJ：子宫切除术并不增高心脏病风险

与一些晚期研究相反，一项新的英国研究推断出中会年男同性恋顺利进行睾丸结扎（；还有或不；还有生殖细胞开刀）后，高血压疾病的效用不曾上升。这些男同性恋高血压病的效用极为很低大自然绝经的男同性恋，该新研究却说。

芝加哥大学首席女作家Karen A. Matthews及同事在一份报告中会写下了他们的推断出，这份报告计划于本周Skype发布于《英国肺炎学会杂志》。

Matthews，芝加哥的一位杰出的精神病学教授和系统性与认知科学教授，在一份新闻公报中会声明，这些结果对刚刚选择睾丸结扎的中会年男同性恋来却说必要是鼓舞人心的：

“研究结果表明，近似于大自然绝经后，睾丸结扎后的高血压病效用生物体程度不大也许上升，”Matthews却说。

睾丸结扎与高血压病效用

睾丸结扎是一种常见的移除男同性恋睾丸的治疗操控。有时，病人还移除生殖细胞，以减缓生殖细胞癌效用。

有时也许明显需要顺利进行该操控，比如因为肺癌、睾丸下垂、外皮样肌瘤，或因为颇为重的迟于过多与不止经，但与此同时，和所有治疗一样，仍要权衡其收益与效用。

因为雄激素忽略，在绝经前顺利进行睾丸结扎常引发格外年期提更早。

一些晚期研究表明睾丸结扎提高高血压疾病的长期效用，而高血压疾病是男同性恋头号杀手。而且他们推断，如果同时开刀生殖细胞，该效用将格外高。

但是该见解只不过，主要因为这些研究排斥于评估睾丸结扎与/或生殖细胞结扎多年之后的高血压病效用，而从未将她们在治疗之前就也许有的效用选择进去。

科学界们来作了什么

而在该项新研究中会，Matthews及其同事随访了3,302位英国绝经前男同性恋11年。这些男同性恋参加了全国男同性恋研究（SWAN）。

研究伊始，当这些男同性恋投身到SWAN时，她们42-52岁，睾丸比较简单，有将近1个生殖细胞，且从未使用激素疗法。

在随访期间，每年给她们来作评估。在此期间，大部分男同性恋达到大自然绝经平均年龄，一些顺利进行了睾丸结扎；还有生殖细胞结扎，而一些则不；还有生殖细胞结扎。

顺利进行睾丸结扎的主要理由是外皮样肌瘤、迟于过多和慢性下颚不止。

科学界在睾丸结扎前后评估了参与者的高血压病效用，并将这些数据与那些大自然绝经的男同性恋最后一次迟于前后的效用相比。

Matthews及其同事却说，他们的研究是时是多民族研究，了顺利进行睾丸结扎与大自然绝经的男同性恋的高血压病效用生物体的每年预期忽略。

推断出了什么

该分析辨识睾丸结扎前后与大自然绝经前后高血压效用生物体遭遇变化，在不同个体，睾丸结扎者与大自然绝经者变化方式大不相同；同时，总体变化方式辨识睾丸结扎者高血压效用不曾上升，科学界们却说。并且，此情况在所有种族组都一样。

并且，即使在调整也许的阻碍生物体——比如人体质量标准普尔（BMI）——之后，情况仍一样。睾丸结扎；还有生殖细胞结扎后，BMI确有有所上升。

理由是什么

Mathews却说他们极为相符为什么他们的推断出与辨识睾丸结扎上升时高血压病效用的晚期研究不同。

一个理由也许是，他们从未将年轻男同性恋纳入研究，而格外更早顺利进行睾丸结扎引发的高血压病效用格外高。

另一个理由，Matthews却说，也许是因为该研究排除了因为肺癌而顺利进行睾丸结扎的男同性恋。

SWAN由各地区老年医学研究所、国立护理研究所、国立公共卫生研究院、男同性恋健康实验室和缺少与替代该中会心共同发起。

2011年，《内物理档案》杂志写道，来自旧金山宾夕法尼亚大学的科学界们报道，他们推断出顺利进行了睾丸结扎；还有生殖细胞结扎的男同性恋遭遇生殖细胞癌的效用减缓，并且遭遇其它型式肺癌、肺炎或髋骨折的效用不曾上升时。

原文阅读：Hysterectomy does not increase risk of cardiovascular diseasePositive findings differ from previous studies on hysterectomy, heart disease riskHing a hysterectomy with or without ovary removal in mid-life does not increase a woman's risk of cardiovascular disease compared to women who reach natural menopause, contrary to many previously reported studies, according to research published online today in the Journal of the American College of Cardiology."Middle-aged women who are considering hysterectomy should be encouraged because our results suggest that increased levels of cardiovascular risk factors are not any more likely after hysterectomy relative to after natural menopause," said Karen A. Matthews, PhD, lead author of the study and a distinguished professor of psychiatry and professor of epidemiology and psychology at the University of Pittsburgh.Hysterectomy is the surgical removal of a woman's uterus; it is sometimes accompanied by the removal of the ovaries to decrease the risk of ovarian cancer. Hysterectomy is a common surgical procedure for women, but the benefits must be weighed against potential long-term related health consequences. Cardiovascular disease is the number one killer of women and many studies he shown increased risk of cardiovascular disease to be a health risk associated with hysterectomy, especially accompanied by ovary removal. Researchers in those studies usually evaluated cardiovascular disease risk factors years after hysterectomy and/or ovary removal and did not assess individual risk factor levels pre-surgery.For this study, investigators followed 3,302 premenopausal women between the ages of 42-52 for 11 years who were enrolled in the Study of Women's Health across the Nation (SWAN). Researchers compared cardiovascular disease risk factors in women prior to and following elective hysterectomy with or without ovary removal to the risk factors prior to and following final menstrual period in women who underwent natural menopause.This is the only multiethnic study that has tracked prospective annual changes in cardiovascular disease risk factors relative to hysterectomy or natural menopause.Investigators found that several cardiovascular disease risk factor changes differed prior to and following hysterectomy, compared to changes prior to and following a natural menopause, but those changes did not suggest an increased cardiovascular disease risk following hysterectomy, independent of body mass index, which did increase after hysterectomy with removal of ovaries. These effects were similar in all ethnic groups in the study.Dr. Matthews said it is unclear why this study's findings differed from other studies exploring hysterectomy and cardiovascular risk, but likely factors include the age of participants since hysterectomy that occurs earlier in life may present more cardiovascular risk. Also, earlier studies included women who had hysterectomy for any reason, whereas the SWAN study excluded women who had hysterectomy because of cancers. "This study will prove very reassuring to women who he undergone hysterectomy," said American College of Cardiology CardioSmart Chief Medical Expert JoAnne Foody, MD, FACC. "As with anything, if a woman is concerned about her risk for heart disease she should discuss this with her health care provider."
