    该研究的目的是评估在羔羊日粮中加入可可麸皮的影响及其对生殖参数的影响。为此,40只羔羊被随机分配到四个治疗,并且在浓缩物中包括0、10、20和30%水平的可可麸皮。收集血液以测量胆固醇和睾丸激素以及精液以进行物理和形态学评估;还评估了睾丸生物计量学和形态计量学。对照处理的羔羊体重和肾小管指数与30%可可麸皮处理的羔羊之间存在显着差异(P<0.05)。睾丸生物测量没有差异,新鲜精液的物理和形态参数,睾丸形态测量,所有处理的羔羊体积比(P<0.05)。此外,血浆胆固醇和睾酮浓度差异无统计学意义(P>0.05)。因此,可以在饮食中包含高达30%的可可麸皮,而不会影响羔羊的生殖参数。
    The objective of the study was to evaluate the effect of the inclusion of cocoa bran in the diet of lambs and its effect on reproductive parameters. For this, 40 lambs were randomly assigned to four treatments, and including 0, 10, 20 and 30% levels of cocoa bran in the concentrate. Blood was collected to measure cholesterol and testosterone and semen for physical and morphological evaluation; testicular biometry and morphometry were also evaluated. There was significant difference (P < 0.05) in body weight and tubulosomatic index between the lambs in the control treatment and those in the 30% cocoa bran treatment. There was no difference in testicular biometry, physical and morphological parameters of fresh semen, testicular morphometry, and volumetric ratio between lambs in all the treatments (P < 0.05). In addition, there was no difference in plasma cholesterol or testosterone concentration (P > 0.05). Thus, it is possible to include up to 30% of cocoa bran in diet without affecting the reproductive parameters of lambs.

    背景:减肥手术对肥胖和性腺功能减退症男性睾酮水平的影响尚未得到彻底研究。
    目的:通过使用综合索赔数据库比较手术前后的T水平,研究减肥手术对肥胖性腺功能减退男性T水平的可能影响。
    方法:TriNetXUS协作网络数据库用于识别18-80岁接受减肥手术且手术前血清T值<350ng/dL的男性。在手术前/后接受睾酮治疗的男性被排除在外。我们进行了一项回顾性的自我匹配队列分析,以检查减重手术前后血清T水平的差异。进行了分分析,以探讨手术后达到性腺正常状态或维持低T水平的男性之间的差异。描述性统计详细的社会人口统计学和临床特征,使用非配对t检验和卡方分析比较连续和分类数据,分别。使用非配对t检验比较手术前后T水平和体重指数(BMI)的变化,显著性<0.05。所有分析均使用利用Python和R软件的TriNetX平台进行。
    结果:该研究分析了69名接受减肥手术并在手术前后评估T水平的性腺功能减退男性。术前血清T水平的平均值(标准差)为208±79ng/dL,术后增加到371±164ng/dL,标记平均增加163±164ng/dL。同样,平均(标准偏差)体重指数从42.9±9.0下降到38.8±5.7kg/m2。手术后,45%(31名男性)达到了性腺状态,而55%(38名男性)的T水平仍然较低。术后正常性腺队列和持续低T队列之间的比较显示,前者具有较高的术前血清T水平(235±71ng/dL与184±80.4ng/dL,p=0.007),术前体重指数较高(45.5±4.5kg/m2vs.41.1±11.5kg/m2,p=0.041),术后体重指数明显降低(7.3±7.2kg/m2vs.2.0±12.8kg/m2,p=0.04)。值得注意的是,与持续性低睾酮队列相比,性腺正常队列中T的增加明显更高(257±143ng/dLvs.95±178纳克/分升,p<0.0001)。
    结论:这项研究提供了减肥手术对基线低T肥胖男性血清T水平有积极影响的证据。作为迄今为止最全面的研究,它验证并证实了先前的工作,表明减肥可以从生理上改善T水平。
    BACKGROUND: The effects of bariatric surgery on testosterone levels in men with obesity and hypogonadism have not been thoroughly explored yet.
    OBJECTIVE: To investigate the possible effects of bariatric surgery on T levels in obese hypogonadal men by comparing T levels before and after surgery using a comprehensive claims database.
    METHODS: The TriNetX US Collaborative Network database was used to identify men ages 18-80 who underwent a bariatric procedure and had a serum T value of < 350 ng/dL prior to surgery. Men who received testosterone therapy before/or after surgery were excluded. We conducted a retrospective self-matched cohort analysis to examine the difference in serum T levels before and after bariatric surgery. A sub-analysis was carried out to explore differences between men who reached eugonadal status or maintained low T levels following surgery. Descriptive statistics detailed sociodemographic and clinical characteristics, with continuous and categorical data compared using unpaired t-tests and chi-square analysis, respectively. Changes in T levels and body mass index (BMI) before and after surgery were compared using an unpaired t-test with a < 0.05 set for significance. All analyses were conducted using the TriNetX platform which utilizes both Python and R software.
    RESULTS: The study analyzed 69 hypogonadal men who underwent bariatric surgery and had T levels assessed before and after the procedure. The mean (standard deviation) pre-surgery serum T level was 208 ± 79 ng/dL, which post-surgery increased to 371 ± 164 ng/dL, marking an average increase of 163 ± 164 ng/dL. Likewise, the mean (standard deviation) body mass index decreased from 42.9 ± 9.0 to 38.8 ± 5.7 kg/m2. Post-surgery, 45% (31 men) achieved eugonadal status, while 55% (38 men) continued to have low T levels. A comparison between the post-surgery eugonadal cohort and the persistent low T cohort revealed that the former had higher pre-surgery serum T levels (235 ± 71 ng/dL vs. 184 ± 80.4 ng/dL, p = 0.007), a higher pre-surgery body mass index (45.5 ± 4.5 kg/m2 vs. 41.1 ± 11.5 kg/m2, p = 0.041), and a significantly greater reduction in body mass index post-surgery (7.3 ± 7.2 kg/m2 vs. 2.0 ± 12.8 kg/m2, p = 0.04). Notably, the increase in T was significantly higher in the eugonadal cohort compared to the persistent low testosterone cohort (257 ± 143 ng/dL vs. 95 ± 178 ng/dL, p < 0.0001).
    CONCLUSIONS: This study provides evidence of bariatric surgery\'s positive effect on serum T levels in obese men with baseline low T. Almost one out of two men with low T reached normal T levels after bariatric surgery. As the most comprehensive study to date, it validates and substantiates previous work suggesting that weight loss can improve T levels physiologically.

    背景:全球,不育影响约15%的育龄夫妇。在许多情况下,不孕症无法治疗,然而,在最近的临床试验中,新的有价值的治疗方案已经涉及.这项临床试验的目的是评估在来曲唑中添加辅酶Q10(CoQ10)对诊断为特发性少弱精子症(iOAT)综合征的男性精子图和性激素测试结果的影响。这是一种病因不明的男性精子发生缺陷。方法:随机,开放标签,平行的双臂介入研究包括67名年龄在18-60岁的成年男性患者,这些患者被确诊为iOAT综合征,这些患者来自Nahrain大学不孕诊断和辅助生殖技术高级研究所。将患者随机分为两组,A组包括29例患者,每周两次口服来曲唑2.5mg片剂,B组包括38例患者,每周两次口服来曲唑2.5mg片剂,每天400mg辅酶Q10。两组均治疗3个月。精液样本,血清卵泡刺激素(FSH),雌二醇(E2),和睾酮(T)在第一天进行分析,在第一个月底,两个和三个。结果:两组精子浓度,形态正常,精子总数和活力,血清睾酮和FSH水平,T/E2比值显著增加,而雌二醇水平在治疗三个月后显著下降。仅A组精液体积变化明显。在两组比较中,所有测量参数,除了精子活力和FSH水平,治疗三个月后表现出显著差异,而精子体积在治疗仅两个月后就达到了显著值。结论:CoQ10作为来曲唑的辅助治疗有效地改善了iOAT伊拉克男性的大多数测试精子参数。注册:ClinicalTrials.gov(NCT05847257,2023年5月6日)。
    Background: Worldwide, infertility affects about 15% of reproductive-age couples. In many cases, infertility can\'t be treated, however new treatment options with promising value have been involved in recent clinical trials. The aim of this clinical trial was to evaluate the impacts of adding coenzyme Q10 (CoQ10) to letrozole on the results of spermiogram and sex hormone tests in men diagnosed with idiopathic oligoasthenoteratozoospermia (iOAT) syndrome, which is a type of male defective spermatogenesis of unknown etiology. Methods: This randomized, open-label, parallel two-arm interventional study included 67 adult male patients aged 18-60 years with a confirmed diagnosis of iOAT syndrome recruited from The High Institute for Infertility Diagnosis & Assisted Reproduction Technologies/Nahrain University. Patients were randomly separated into two groups, Group A included 29 patients treated with letrozole 2.5 mg tablet orally twice a week, Group B included 38 patients treated with a combination of letrozole 2.5 mg tablet orally twice a week plus CoQ10 400 mg per day. Both groups completed treatment for three months. Semen samples, serum follicle-stimulating hormone (FSH), estradiol (E 2), and testosterone (T) were analyzed at day one, and at the end of month one, two and three. Results: Both groups showed that sperm concentration, normal morphology, total sperm count and motility, serum testosterone and FSH levels, and T/E 2 ratio were significantly increased, while estradiol levels significantly decreased after three months of treatment. Seminal fluid volume changed significantly in group A only. In comparing between the two groups, all measured parameters, apart from sperm motility and FSH level, demonstrated a significant difference after three months of treatment, while sperm volume reached significant value after only two months of therapy. Conclusions: CoQ10 as adjuvant treatment to letrozole effectively improved most of the tested sperm parameters in Iraqi men with iOAT. Registration: ClinicalTrials.gov ( NCT05847257, May 6, 2023).

    尽管用于治疗育龄妇女乳腺癌的化疗方案对卵巢储备的有害影响已被广泛研究,几乎没有关于这些方案对卵泡膜细胞功能和卵巢雄激素分泌的影响的报道。这项前瞻性多中心队列研究的目的是描述250例<40年乳腺癌患者在化疗和24个月随访期间的血清总睾酮和雄烯二酮水平。诊断时雄烯二酮和总睾酮的平均基础水平分别为1.68ng/mL和0.20ng/mL。与年龄无关。化疗完成后,雄烯二酮和总睾酮的血清水平迅速下降,在2年随访期间,所有患者均缓慢升高并几乎恢复至基础水平。总之,我们的研究证明了化疗引起的卵巢皮层功能改变,导致血清雄激素水平显着下降。卵泡膜细胞功能的这种改变增加了众所周知的颗粒细胞功能的改变,导致一个全球性的,但部分是短暂的,接受乳腺癌治疗的年轻女性的卵巢衰竭。这些数据为卵巢生理学带来了新的见解,并强调了治疗前后卵巢随访的必要性。试用注册:ClinicalTrial.gov标识符NCT01114464。
    Although the deleterious impact of chemotherapy regimen used to treat women of reproductive age with breast cancer on ovarian reserve has been extensively studied, hardly anything has been reported on the effect of these protocols on theca cell function and ovarian androgen secretion. The aim of this prospective multicentric cohort study was to describe serum levels of total testosterone and androstenedione during chemotherapy and 24-month follow-up in 250 patients <40 years treated for breast cancer. Mean basal levels of androstenedione and total testosterone at diagnosis were 1.68 ng/mL and 0.20 ng/mL respectively. No correlation with age was found. Serum levels of androstenedione and total testosterone rapidly decreased after chemotherapy completion, before slowly increasing and almost returning to basal levels in all patients during 2-year follow-up. In conclusion our study demonstrates a chemotherapy-induced alteration of ovarian thecal function, resulting in a significant decrease in serum androgen levels. This alteration of theca cell function adds to the well-known alteration of granulosa cell function, resulting in a global, but partly transient, ovarian failure in young women treated for breast cancer. These data bring new insight into ovarian physiology and emphasize the need for pre and post-treatment ovarian follow-up. Trial registration: ClinicalTrial.gov identifier NCT01114464.

    多囊卵巢综合征(PCOS)是育龄妇女中最常见的内分泌和代谢紊乱之一。它经常与肥胖和负面情绪并存。目前,关于PCOS患者肥胖与负性情绪关系的报道较少。在这里,我们进行了基础和临床研究,以研究PCOS中肥胖与负面情绪之间的关系。
    我们进行了一项横断面研究,包括608名PCOS患者和184名健康参与者,以评估具有不同体重指数(BMI)的人的心理健康状况。自我评估的焦虑,抑郁症,感知压力量表用于主观情绪评估。饲喂45%和60%高脂肪饮食的大鼠PCOS模型用于证实临床研究的结果。使用高架迷宫和空场测试来评估大鼠的焦虑和抑郁样行为。
    我们观察到超重/肥胖,抑郁症加重,焦虑,以及PCOS女性的感知压力,发现重度肥胖和PCOS患者的焦虑和抑郁与BMI呈负相关。在动物研究中证实了类似的结果;升高的迷宫试验和野外试验表明,只有60%的高脂饮食诱导的肥胖部分逆转了PCOS大鼠的焦虑和抑郁样行为。高脂饮食还可以调节大鼠下丘脑和海马黄体生成素和睾丸激素水平。
    这些结果揭示了PCOS患者肥胖与负面情绪之间的潜在关系,并促使进一步调查。PCOS的各种症状之间的相互作用可能是有针对性的,以改善患者的整体健康状况。
    PCOS患者肥胖与负性情绪呈负相关。肥胖可能影响LH和睾酮的下调,参与情绪调节。在心理方面,增加的BMI可能对PCOS患者有益。
    UNASSIGNED: Polycystic ovary syndrome (PCOS) is one of the most common endocrine and metabolic disorders in women of reproductive age. It is frequently comorbid with obesity and negative emotions. Currently, there are few reports on the relationship between obesity and negative emotions in patients with PCOS. Here we performed both basic and clinical studies to study the relationship between obesity and negative emotions in PCOS.
    UNASSIGNED: We performed a cross-sectional study including 608 patients with PCOS and 184 healthy participants to assess the mental health status of people with different body mass indices (BMI). Self-rated anxiety, depression, and perceived stress scales were used for subjective mood evaluations. Rat PCOS models fed 45 and 60% high-fat diets were used to confirm the results of the clinical study. Elevated plus maze and open field tests were used to assess anxiety- and depression-like behaviors in rats.
    UNASSIGNED: We observed overweight/obesity, increased depression, anxiety, and perceived stress in women with PCOS, and found that anxiety and depression were negatively correlated with BMI in patients with severe obesity and PCOS. Similar results were confirmed in the animal study; the elevated plus maze test and open field test demonstrated that only 60% of high fat diet-induced obesity partly reversed anxiety- and depression-like behaviors in PCOS rats. A high-fat diet also modulated rat hypothalamic and hippocampal luteinizing hormone and testosterone levels.
    UNASSIGNED: These results reveal a potential relationship between obesity and negative emotions in PCOS and prompt further investigation. The interactions between various symptoms of PCOS may be targeted to improve the overall well-being of patients.
    Obesity was negatively correlated with negative emotions in patients with PCOS.Obesity may affect the downregulation of LH and testosterone and participate in the regulation of emotions.Increased BMI may be beneficial for patients with PCOS in terms of the psychological aspects.

    背景:性别确认睾酮治疗(TT)对乳腺癌风险的影响尚不清楚。这项研究调查了跨男性个体(TMI)中TT与乳腺组织组成和乳腺组织密度之间的关联。
    方法:在2013年至2019年期间接受胸部轮廓手术的444个TMI中,病理学家在425个TMI中评估了乳腺组织组成(小叶萎缩和基质组成的类别),并使用我们的自动化深度学习算法(百分比上皮,%纤维基质,和%脂肪)。444个TMI中有42个在手术前进行了乳房X线照相术,放射科医生读取了它们的乳腺组织密度。乳房X线摄影数字文件,适用于25/42TMI,使用LIBRA软件进行分析以获得百分比密度,绝对密集区域,和绝对非密集区域。线性回归用于描述TT使用持续时间与乳腺组织组成或乳腺组织密度测量值之间的关联。同时调整潜在的混杂因素。还进行了按体重指数分层的分析。
    结果:长期使用TT与小叶萎缩程度增加有关(p<0.001),但与纤维含量无关(p=0.82)。每6个月的TT与上皮(exp(β)=0.97,95%CI0.95,0.98,调整p=0.005)和纤维基质(exp(β)=0.99,95%CI0.98,1.00,调整p=0.05)的数量减少有关,但不是脂肪(exp(β)=1.01,95CI0.98,1.05,adjp=0.39)。在超重/肥胖TMI中,TT对乳腺上皮的影响减弱(exp(β)=0.98,95%CI0.95,1.01,adjp=0.14)。比较TT用户和非用户时,TT使用者的上皮减少了28%(exp(β)=0.72,95%CI0.58,0.90,adjp=0.003)。TT与放射科医师的乳腺密度评估(p=0.58)或LIBRA测量值(p>0.05)无相关性。
    结论:TT减少乳腺上皮,但这种效应在超重/肥胖TMI中减弱。TT有可能影响TMI的乳腺癌风险。需要进一步的研究来阐明TT对乳腺密度和乳腺癌风险的影响。
    BACKGROUND: The effect of gender-affirming testosterone therapy (TT) on breast cancer risk is unclear. This study investigated the association between TT and breast tissue composition and breast tissue density in trans masculine individuals (TMIs).
    METHODS: Of the 444 TMIs who underwent chest-contouring surgeries between 2013 and 2019, breast tissue composition was assessed in 425 TMIs by the pathologists (categories of lobular atrophy and stromal composition) and using our automated deep-learning algorithm (% epithelium, % fibrous stroma, and % fat). Forty-two out of 444 TMIs had mammography prior to surgery and their breast tissue density was read by a radiologist. Mammography digital files, available for 25/42 TMIs, were analyzed using the LIBRA software to obtain percent density, absolute dense area, and absolute non-dense area. Linear regression was used to describe the associations between duration of TT use and breast tissue composition or breast tissue density measures, while adjusting for potential confounders. Analyses stratified by body mass index were also conducted.
    RESULTS: Longer duration of TT use was associated with increasing degrees of lobular atrophy (p < 0.001) but not fibrous content (p = 0.82). Every 6 months of TT was associated with decreasing amounts of epithelium (exp(β) = 0.97, 95% CI 0.95,0.98, adj p = 0.005) and fibrous stroma (exp(β) = 0.99, 95% CI 0.98,1.00, adj p = 0.05), but not fat (exp(β) = 1.01, 95%CI 0.98,1.05, adj p = 0.39). The effect of TT on breast epithelium was attenuated in overweight/obese TMIs (exp(β) = 0.98, 95% CI 0.95,1.01, adj p = 0.14). When comparing TT users versus non-users, TT users had 28% less epithelium (exp(β) = 0.72, 95% CI 0.58,0.90, adj p = 0.003). There was no association between TT and radiologist\'s breast density assessment (p = 0.58) or LIBRA measurements (p > 0.05).
    CONCLUSIONS: TT decreases breast epithelium, but this effect is attenuated in overweight/obese TMIs. TT has the potential to affect the breast cancer risk of TMIs. Further studies are warranted to elucidate the effect of TT on breast density and breast cancer risk.

    背景:神经性厌食症(AN)患者的血浆脂质浓度似乎发生了改变。
    方法:我们对75名患有AN的成年女性患者和26名健康女性对照(HC)进行了一项自然研究。我们测量了血浆脂质分布,性激素并在入院和出院时使用自我报告问卷。
    结果:总胆固醇(中位数(IQR):4.9(1.2))和甘油三酯(TG)(1.2(0.8))在入院时升高(BMI15.3(3.4))与HC(4.3(0.7)相比,p=0.003和0.9(0.3),p=0.006),并在体重恢复治疗后出院时保持升高(BMI18.9(2.9))。与HC相比,AN中的雌二醇(0.05(0.1))和睾丸激素(0.5(0.7))较低(0.3(0.3),p=<0.001和0.8(0.5),p=0.03),并在放电时保持较低。进食障碍症状没有变化。抑郁症状减少(33(17)至30.5(19),(p=0.007))。回归分析显示病程是TG的预测因子,年龄是总胆固醇和低密度脂蛋白的预测因子,而受教育程度预测LDL和TG。
    结论:体重恢复治疗后,脂质浓度仍然升高,暗示了一个潜在的,体重恢复后持续存在的AN中脂质代谢异常。在AN疾病发作之前可能存在脂质浓度升高。
    方法:III:从精心设计的队列或病例对照分析研究中获得的证据。
    脂肪是人体必需的。血液中脂肪过多可能是包括心脏病在内的潜在疾病的征兆。这项研究调查了神经性厌食症(AN)患者的血浆脂质(脂肪)如何受到影响。我们纳入了75名患有AN的成年女性个体和26名健康女性对照,测量脂质,性激素,并在入院和出院时使用问卷。我们发现患有AN的低体重个体的血脂高于健康对照组,这些脂质在体重恢复治疗后仍然升高。此外,患有AN的个体在低体重时性激素(雌二醇和睾丸激素)水平较低,即使在体重恢复治疗后,它们也保持较低。进食障碍症状保持不变,但抑郁症状在治疗期间有所减轻。总之,这项研究表明,患有AN的个体的脂质代谢发生变化,即使在体重恢复治疗后仍然存在。我们不知道这些脂质升高背后的原因,因此,这应该在未来的研究中进一步研究。
    BACKGROUND: Plasma lipid concentrations in patients with anorexia nervosa (AN) seem to be altered.
    METHODS: We conducted a naturalistic study with 75 adult female patients with AN and 26 healthy female controls (HC). We measured plasma lipid profile, sex hormones and used self-report questionnaires at admission and discharge.
    RESULTS: Total cholesterol (median (IQR): 4.9 (1.2)) and triglycerides (TG) (1.2 (0.8)) were elevated in AN at admission (BMI 15.3 (3.4)) compared with HC (4.3 (0.7), p = 0.003 and 0.9 (0.3), p = 0.006) and remained elevated at discharge (BMI 18.9 (2.9)) after weight restoration treatment. Estradiol (0.05 (0.1)) and testosterone (0.5 (0.7)) were lower in AN compared with HC (0.3 (0.3), p =  < 0.001 and 0.8 (0.5), p = 0.03) and remained low at discharge. There was no change in eating disorder symptoms. Depression symptoms decreased (33 (17) to 30.5 (19), (p = 0.007)). Regression analyses showed that illness duration was a predictor of TG, age was a predictor of total cholesterol and LDL, while educational attainment predicted LDL and TG.
    CONCLUSIONS: Lipid concentrations remained elevated following weight restoration treatment, suggesting an underlying, premorbid dysregulation in the lipid metabolism in AN that persists following weight restoration. Elevated lipid concentrations may be present prior to illness onset in AN.
    METHODS: III: Evidence obtained from well-designed cohort or case-control analytic studies.
    Fat is essential for the human body. Too much fat in the blood can be a sign of underlying illness including heart disease. This study investigated how plasma lipids (fats) are affected in individuals with anorexia nervosa (AN). We included 75 adult female individuals with AN and 26 healthy female controls, and measured lipids, sex hormones, and used questionnaires upon admission and discharge from treatment. We found that low-weight individuals with AN had higher lipids than the healthy controls, and these lipids remained elevated after weight restoration treatment. Additionally, individuals with AN had lower levels of sex hormones (estradiol and testosterone) at their low weight, and they stayed low even after weight restoration treatment. Eating disorder symptoms remained unchanged, but depression symptoms decreased during treatment. In conclusion, the study suggests that individuals with AN have changes in their lipid metabolism, which persists even after weight restoration treatment. We don’t know the reason behind these elevated lipids, and therefore, this should be investigated further in future study.

    2D:4D数字比通常用作可能反映产前睾丸激素水平的替代指标。间接证据来自研究2D:4D与可能与产前睾丸激素有关的人类特征之间的关联。在儿童中,性别类型的游戏在发育早期显示出很大的性别差异,并且可能受到产前睾丸激素的影响。关于2D:4D和儿童性别类型游戏之间的关联的发现是异质的,并且已经提出了对性别类型游戏发展的其他影响,最重要的社会影响,比如兄弟姐妹,他们的性别和出生顺序。当前的研究检查了左右2D:4D之间的关联,产前睾酮暴露的拟议替代品,对N=505名6个月大的儿童的右手和左手进行了评估,和性别类型的游戏行为,3.5年后,使用学前活动清单(PSAI)对其进行了评估,和兄弟姐妹的影响。为了捕捉兄弟姐妹性别和出生顺序的不同影响,使用虚拟编码变量来反映没有兄弟姐妹以及年长或年幼的姐妹或兄弟。使用多元回归模型来研究PSAI评分与性别之间的关系,左右2D:4D,既是单身,又有姐姐或弟弟。研究表明,性别和有一个哥哥是性别类型游戏的重要预测因素。通过对男孩和女孩进行单独的回归分析,进一步解开了影响。在男孩中,揭示了PSAI分数和有哥哥之间的显著关联,在女孩身上,未发现显著关联.讨论了结果,突出了2D:4D与儿童性别类型游戏之间的非显着关联,这削弱了2D:4D作为反映产前T影响的替代的适用性。讨论了兄弟姐妹等社会因素对儿童性别类型游戏的重要性。
    The 2D:4D digit ratio is commonly used as a surrogate possibly reflecting prenatal testosterone levels. Indirect evidence comes from studies investigating the association between 2D:4D and human characteristics that likely relate to prenatal testosterone. In children, sex-typed play reveals large sex differences early in development and an influence of prenatal testosterone is likely. Findings on the association between 2D:4D and children\'s sex-typed play are heterogeneous and other influences on the development of sex-typed play have been suggested, most of all social influences like siblings, their sex and birth order. The current study examined the association between right and left 2D:4D, a proposed surrogate for prenatal testosterone exposure, which was assessed in right and left hands of N = 505 6-month-old children, and sex-typed play behavior, which was evaluated 3.5 years later using the Pre-School Activities Inventory (PSAI), and the influence of siblings. To capture differential effects of siblings\' sex and birth order, dummy-coded variables were used reflecting having no siblings as well as older or younger sisters or brothers. Multiple regression models were used to investigate the association between PSAI scores and sex, right and left 2D:4D, being a singleton as well as having an older or younger sister or brother. It was shown that sex and having an older brother were significant predictors for sex-typed play. Effects were further disentangled by conducting separate regression analyses in boys and girls. In boys, a significant association between PSAI scores and having an older brother was revealed, in girls, no significant associations were found. Results are discussed highlighting the non-significant association between 2D:4D and children\'s sex-typed play, which weakens the applicability of 2D:4D as a surrogate reflecting influences of prenatal T. Further, the importance of social factors like siblings on children\'s sex-typed play is discussed.

    结果:在接受调查的150名男性运动员中,121人完成问卷(回复率:80.6%)。超过一半的人年龄在18至23岁之间(56.2%),单身(79.3%)。32%的人报告使用合成代谢类固醇,主要是为了增加肌肉质量,遵循教练的建议(46.1%)。主要来源包括互联网(30.7%),教练(30%),和朋友(27.9%),非医疗保健专业人员。最主要的动机是价格,教练/医生的建议,和可用性。感知的好处包括增加肌肉质量,力量,和耐力,而感知到的不良反应包括肾/肝损害和性问题。
    结论:接受调查的男性运动员中有三分之一使用合成代谢类固醇,受可访问性和社会接触的影响,而不是医疗指导。这突出表明需要提高对长期健康风险的认识,理想情况下,通过运动医学专家提供的教育。
    OBJECTIVE: To assess the prevalence of anabolic steroid use and the level of knowledge on anabolic steroids among the male athletes in Al Madina Al Munawara, Saudi Arabia.
    METHODS: A cross-sectional study was conducted on male athletes randomly selected from the private athletic centers in Al Madina Al Munawara over 5 months. Data were collected from all participants using a self-administered anonymous questionnaire with 33 questions. The questionnaire covered the socio-demographic characteristics of the participants, and their knowledge, attitudes, and use of anabolic steroids.
    RESULTS: Of the 150 male athletes surveyed, 121 completed the questionnaire (response rate: 80.6%). Over half were aged between 18 and 23 years (56.2%) and were single (79.3%). Thirty-two percent reported using anabolic steroids, mainly to increase muscle mass, following coaches\' advice (46.1%). Key sources included the internet (30.7%), coaches (30%), and friends (27.9%), and non-healthcare professionals. The top motivations were price, coach\'s/physician\'s advice, and availability. The perceived benefits included increased muscle mass, strength, and endurance, while the perceived adverse effects included kidney/liver damage and sexual problems.
    CONCLUSIONS: One-third of the male athletes surveyed used anabolic steroids, influenced by accessibility and social contact, rather than healthcare guidance. This highlights the need for greater awareness of the long-term health risks, ideally through education provided by sports medicine specialists.

  • 文章类型: Journal Article
    性别确认激素治疗(GAHT)是变性人减少性别焦虑和改善生活质量的常用疗法。澄清GAHT的长期影响仍然是跨性别健康研究的优先事项。
    与顺性退伍军人相比,探讨性激素(雌二醇和睾丸激素)是否与跨性别退伍军人的代谢综合征发展有关。
    这次回顾展,纵向队列研究采用国际疾病分类,第九次修订和国际疾病和相关健康问题统计分类,来自退伍军人健康管理局国家数据库的性别烦躁不安的第十次修订诊断代码,以识别从2006年1月1日至2019年12月31日接受记录的女性化(雌二醇)或男性化(睾丸激素)治疗的跨女性和跨男性退伍军人,以及GAHT开始日期和代谢综合征成分相关数据可用。变性人退伍军人与顺性人所指者相匹配。
    性别确认激素治疗。
    根据体重指数计算代谢综合征z评分,收缩压,和高密度脂蛋白胆固醇水平,甘油三酯,和血糖。使用重复测量的方差分析模型,在索引日期(对应于GAHT开始)之前和之后,比较了跨性别和顺性别组的平均z得分变化。
    该队列包括1290名参与者:645名变性人(494[38.3%]跨女性,151[11.7%]跨男性)和645顺性(280[21.7%]女性,365[28.3%]男性)。索引日期的平均(SD)年龄为41.3(13.2)岁。代谢综合征z评分随着时间的推移而显着变化,并且各组之间存在显着差异。总的来说,跨男性退伍军人在指数日期之后与之前相比,平均(SEM)z分数的百分比增加最大(298.0%[57.0%];P<.001),其次是顺性女性(108.3%[27.5%];P<.001),顺性男性(49.3%[27.5%];P=0.02),和跨女性人士(3.0%[10.7%];P=.77)。
    在这项队列研究中,在顺性人和变性人退伍军人中,雌二醇与代谢综合征风险降低相关,而睾酮与风险增加相关。然而,跨男性个体患与这些激素相关的代谢综合征的风险最高,跨女性个体患代谢综合征的风险最低.这与顺性者和变性者代谢综合征危险因素的管理有关,并可能预测动脉粥样硬化性心血管疾病的风险。2型糖尿病,收缩期高血压,胰岛素抵抗,和非酒精性脂肪性肝病。
    UNASSIGNED: Gender-affirming hormone treatment (GAHT) is a common therapy for transgender individuals to reduce gender dysphoria and improve quality of life. Clarifying the long-term effects of GAHT remains a priority in transgender health research.
    UNASSIGNED: To explore whether sex hormones (estradiol and testosterone) are associated with the development of metabolic syndrome in transgender veterans compared with cisgender veterans.
    UNASSIGNED: This retrospective, longitudinal cohort study used International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis codes for gender dysphoria from the Veterans Health Administration national database to identify transfeminine and transmasculine veterans receiving documented feminizing (estradiol) or masculinizing (testosterone) treatment from January 1, 2006, to December 31, 2019, and for whom the GAHT initiation date and metabolic syndrome component-related data were available. Transgender veterans were matched to cisgender referents.
    UNASSIGNED: Gender-affirming hormone treatment.
    UNASSIGNED: Metabolic syndrome z-scores were calculated based on body mass index, systolic blood pressure, and levels of high-density lipoprotein cholesterol, triglycerides, and blood glucose. Changes in mean z-scores were compared among the transgender and cisgender groups before and after the index date (corresponding to GAHT initiation) using a repeated-measures analysis of variance model.
    UNASSIGNED: The cohort included 1290 participants: 645 transgender (494 [38.3%] transfeminine, 151 [11.7%] transmasculine) and 645 cisgender (280 [21.7%] female, 365 [28.3%] male). Mean (SD) age at the index date was 41.3 (13.2) years. Metabolic syndrome z-scores changed significantly over time and differed significantly across groups. Overall, transmasculine veterans had the greatest percentage increase in mean (SEM) z-scores after vs before the index date (298.0% [57.0%]; P < .001), followed by cisgender females (108.3% [27.5%]; P < .001), cisgender males (49.3% [27.5%]; P = .02), and transfeminine persons (3.0% [10.7%]; P = .77).
    UNASSIGNED: In this cohort study, in both cisgender and transgender veterans, estradiol was associated with reduced metabolic syndrome risk, whereas testosterone was associated with increased risk. However, transmasculine individuals had the greatest risk and transfeminine individuals had the lowest risk of metabolic syndrome associated with these hormones. This is relevant for the management of metabolic syndrome risk factors in cisgender and transgender individuals and to potentially predict the risk of atherosclerotic cardiovascular disease, type 2 diabetes, systolic hypertension, insulin resistance, and nonalcoholic fatty liver disease.
