Sci Rep:肥胖节食男性中,睾丸素治疗对骨重建标记和矿物密度的影响研究

2018-06-24 AlexYang MedSci原创

最近,有研究人员在节食肥胖男性中,评估了睾丸素治疗对骨重建和密度的影响。研究包括了100名肥胖男性,平均年龄为53岁(范围为47-60岁),并且他们的总睾丸素水平<12nmlol/L,并接受为期10周的低能量饮食(VLED)。另外,他们进行了为期46周的体重保持,并被随机分配到基点到56周的肌肉内注射十一酸睾酮(n=49)或者匹配的安慰剂组(n=51)。在两组之间预先确定的差异结果(平均调整

最近,有研究人员在节食肥胖男性中,评估了睾丸素治疗对骨重建和密度的影响。研究包括了100名肥胖男性,平均年龄为53岁(范围为47-60岁),并且他们的总睾丸素水平<12nmlol/L,并接受为期10周的低能量饮食(VLED)。另外,他们进行了为期46周的体重保持,并被随机分配到基点到56周的肌肉内注射十一酸睾酮(n=49)或者匹配的安慰剂组(n=51)。

在两组之间预先确定的差异结果(平均调整差,MAD)包括了血清c端交联肽(CTx)、1型原胶原N端前多肽(P1NP)和骨矿物密度(BMD)。在试验结束时,研究人员发现,与安慰剂处理组相比,睾丸素处理小组中CTx显著减少;另外,MAD 为-66ng/L(95% CI -113, -18),p=0.018,并且该值在10周VLED阶段处理后已经减少很明显,MAD -63ng/L (95% CI -108, -18), p=0.018。P1NP在VLED后明显增加,MAD +4.2ug/L (95% CI -0.01, +8.4), p=0.05,但是在研究结束时降低MAD -5.6ug/L (95% CI -10.1, -1.1), p=0.03。研究人员在骨硬化蛋白、腰椎间盘骨密度或者股骨骨密度上没有发现显著的变化。

最后,研究人员指出,在低睾丸素水平的肥胖且经历体重减少的男性中,骨重建标记是被调节的,该过程也许对骨质量有好的影响。

Sci Rep:较低的SHBG水平与较高的瘦蛋白、较低的脂肪连接蛋白水平和代谢综合征有关,而与睾丸素无关

除了睾丸素外(T),性激素结合球蛋白(SHBG)在代谢综合征(MetS)中的角色越来越受到关注并给予了注释。然而,关于血清脂肪细胞因子水平的相关关系研究仍旧十分有限。因此,最近,有研究人员评估了是否血清睾丸素和性激素结合球蛋白是代谢综合征的独立的预测因子。另外,该代谢综合征与脂肪连接蛋白和瘦蛋白相关,且群体为来自一个自由健康筛选的614名台湾地区的年龄不小于40岁的男性。研究发现,最低四分位的睾丸

最近,有研究人员阐释了在大鼠中,百里醌(TQ)对试验条件下诱导的良性前列腺增生(BPH)的发展具有可能的保护性作用。在试验中,18只成年雄性大鼠分为3个小组;阴性对照组(n=6)接受介质注射,另外两个组接受皮下睾丸素注射(3mg/kg)。再将接受睾丸素注射的大鼠随机分成BPH不处理组(n=6)和BPH+TQ处理组(n=6,5mg/kg口服14天)。研究人员还分析了组织学变化和转变生长因子-β1(T

JAMA:看美国的消费广告对睾丸素测试的影响!

2000年至2013年,睾酮素使用在美国开始大幅增加,特别是在没有明显症状的男性中。在此期间,直接消费者广告(DTCA)也有所增加。近期,一项发表在权威杂志JAMA上的研究旨在调查电视DTCA与美国睾丸素测试和使用之间的联系。此项研究在美国指定市场地区(DMAs)进行生态学研究。使用泊松泛化估计方程估计DTCA与睾丸激测试、使用和无最近测试的使用之间的关联。此项研究主要评估(1)新的血清睾酮检测率

Prostate:在过渡区睾丸素和二氢睾酮水平与前列腺体积相关

在前列腺雄激素水平和雄激素在前列腺组织增生方面一直以来都没有形成共识。目前的观点是前列腺二氢睾酮(DHT)浓度是保持的,但是在良性前列腺增生(BPH)中并没有被提高,并且前列腺睾丸素(T)并没有呈现出相似的数据。最近,有研究人员调查了93名计划用于初步前列腺活检的病人的组织T(tT)和组织DHT(tDHT)浓度。生物活检的准则为异常的DRE和/或PSA>4ng/mL。并利用经直肠超声(TRU

Current Bio:睾丸素或缩短男性寿命

在工业化国家,女性的平均寿命比男性至少多5年。科学家将这种差异归因于从更健康的生活方式到更强壮的细胞的诸多因素。如今,一项分析被阉割的男性寿命的新研究表明,睾丸素在缩短男性寿命的过程中扮演了一个重要角色。 作为一种男性激素,睾丸素影响寿命的想法并不新奇。那些被去除了睾丸素来源的绝育的狗和其他动物通常要比它们完整无缺的同类活得更长。然而在人类中进行阉割与寿命之间关系的研究则更为困难,因此其结果尚无

体育比赛可使男性睾丸素飙升

近日,美国华盛顿大学等处的研究人员发现,尽管只踢了10分钟的足球比赛,但这些生活在玻利维亚低地的特希曼男性的睾丸素(一种男性激素)水平却已经比赛前增加了30%。如果这些踢球的人是美国运动员,那么这一数字将是惊人的。然而与发达国家的男性相比,特希曼男性一生中的睾丸素水平都要低得多。这一发现或许为研究人体如何短期和长期调节激素的增长提供了线索。 特希曼人口约15000,他们散居在亚马孙河周围的小村庄
