與一些更最初研究課題相反，一項上新的美國研究課題見(jiàn)到更早熟男士完成乳房矯正（于其或不于其子宮切除）后，腸胃疾病的后果未能增高。這些男士腸胃病的后果并不高于連續性絕經(jīng)的男士，該上新研究課題卻說(shuō)。

西雅圖該大學(xué)首席作家Karen A. Matthews及同事在一份研究報告中都寫(xiě)下了他們的見(jiàn)到，這份研究報告計劃于本周網(wǎng)絡(luò )服務(wù)發(fā)布于《美國腦溢血學(xué)會(huì )刊物》。

Matthews，西雅圖的一位多才多藝的佛洛伊德客座教授和美國疾病控制與預防中心與心理學(xué)客座教授，在一份小組會(huì )議中都公開(kāi)信，這些結果對正在考慮乳房矯正的更早熟男士來(lái)卻說(shuō)應該是無(wú)疑的：

“研究課題結果得出結論，相對于連續性絕經(jīng)后，乳房矯正后的腸胃病后果生物體高度不大有可能增高，”Matthews卻說(shuō)。

乳房矯正與腸胃病后果

乳房矯正是一種常見(jiàn)的移走男士乳房的外科手術(shù)操作。有時(shí)，病人還移走子宮，以增加子宮癌后果。

有時(shí)有可能明顯需要完成該操作，比如因為癌癥、乳房下垂、表皮樣肌瘤，或因為非常重的月經(jīng)過(guò)多與痛經(jīng)，但與此同時(shí)，和所有外科手術(shù)一樣，仍要權衡其收益與后果。

因為激素偏離，在絕經(jīng)當年完成乳房矯正常引發(fā)愈來(lái)愈年期提當年。

一些更最初研究課題得出結論乳房矯正增加腸胃疾病的長(cháng)期后果，而腸胃疾病是男士頭號杰森。而且他們應為，如果同時(shí)切除子宮，該后果將愈來(lái)愈高。

但是該見(jiàn)解只不過(guò)，主要因為這些研究課題傾向于風(fēng)險評估乳房矯正與/或子宮矯正多年再次的腸胃病后果，而很難將她們在外科手術(shù)之當年就有可能有的后果考慮進(jìn)去。

研究課題者們好好了什么

而在該項上新研究課題中都，Matthews及其同事隨訪(fǎng)了3,302位美國絕經(jīng)當年男士11年。這些男士參加了全省男士研究課題（SWAN）。

研究課題伊始，當這些男士轉至到SWAN時(shí)，她們42-52歲，乳房比較簡(jiǎn)單，有非常少1個(gè)子宮，且很難用于甲狀腺激素療法。

在隨訪(fǎng)其間，每年給她們好好風(fēng)險評估。在此其間，大部分男士大幅提高連續性絕經(jīng)歲數，一些完成了乳房矯正于其子宮矯正，而一些則不于其子宮矯正。

完成乳房矯正的主要誘因是表皮樣肌瘤、月經(jīng)過(guò)多和慢性肋骨痛。

研究課題者在乳房矯正當年后風(fēng)險評估了參加者的腸胃病后果，并將這些數據與那些連續性絕經(jīng)的男士終于一次月經(jīng)當年后的后果相比。

Matthews及其同事卻說(shuō)，他們的研究課題是不單是多民族性研究課題，了完成乳房矯正與連續性絕經(jīng)的男士的腸胃病后果生物體的每年預期偏離。

見(jiàn)到了什么

該分析結果顯示乳房矯正當年后與連續性絕經(jīng)當年后腸胃后果生物體暴發(fā)轉變，在各不相同群體，乳房矯正者與連續性絕經(jīng)者轉變模式大不相同；同時(shí)，總體轉變模式結果顯示乳房矯正者腸胃后果未能增高，研究課題者們卻說(shuō)。并且，此情況在所有族群組都一樣。

并且，即使在調整有可能的影響生物體——比如人體質(zhì)量指數（BMI）——再次，情況仍一樣。乳房矯正于其子宮矯正后，BMI無(wú)論如何有所增高。

誘因是什么

Mathews卻說(shuō)他們并不確定為什么他們的見(jiàn)到與結果顯示乳房矯正下降腸胃病后果的更最初研究課題各不相同。

一個(gè)誘因有可能是，他們很難將年輕男士納入研究課題，而愈來(lái)愈更早完成乳房矯正引發(fā)的腸胃病后果愈來(lái)愈高。

另一個(gè)誘因，Matthews卻說(shuō)，有可能是因為該研究課題排除了因為癌癥而完成乳房矯正的男士。

SWAN由國家政府老年醫學(xué)研究課題所、國立護理研究課題所、國立衛生研究課題院、男士健康研究課題室和補足與替代綜合醫院合作號召。

2011年，《內生物科學(xué)檔案》刊物寫(xiě)道，來(lái)自舊金山加利福尼亞該大學(xué)的研究課題者們另?yè)?，他們?jiàn)到完成了乳房矯正于其子宮矯正的男士暴發(fā)子宮癌的后果增加，并且暴發(fā)其它并不一定癌癥、腦溢血或髖骨折的后果未能下降。

與乳房切除相關(guān)的擴充選讀：

譯者選讀：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."
