menstrual irregularities

  • 文章类型: Journal Article
    一种常见的健康问题称为多囊卵巢综合征(PCOS),以不规则的时期为特征,过量的雄激素产生,和多囊卵巢.它是育龄妇女最常见的内分泌紊乱之一,影响全世界4-20%的女性。许多研究发现PCOS的发病和症状与维生素D不足之间存在联系。维生素D不足导致PCOS女性钙失调和卵泡停滞,这与月经不调和生育问题有关。研究已经将PCOS代谢改变与VDR多态性如iApa-I,Taq-I,Cdx2和Fok-I胰岛素抵抗与维生素D直接相关,是PCOS表型最显著的特征之一。因此,提示维生素D治疗可能有助于PCOS患者的胰岛素敏感性。除了胰岛素抵抗,心血管问题是维生素D水平低的PCOS患者所经历的第二种代谢紊乱.在受PCOS影响的女性中,血脂异常与心血管疾病风险增加无关。维生素D通过增加胰岛素产量显著改善葡萄糖代谢,胰岛素受体表达和减少促炎细胞因子。维生素D对与PCOS相关的代谢和生殖功能障碍的影响可能是由对胰岛素抵抗的整体影响介导的。补充维生素D改善月经周期,卵泡生成增加,PCOS患者的血睾酮水平下降,所有这些都对生育能力产生了重大影响。因此,这可能是同时治疗PCOS的前沿治疗策略.
    A common health problem known as polycystic ovarian syndrome (PCOS), is characterized by irregular periods, an excess of androgen production, and polycystic ovaries. It is one of the most prevalent endocrine disorders in women of reproductive age, affecting 4-20% of women worldwide. Numerous studies have found a connection between the onset and symptoms of PCOS and Vitamin D insufficiency. Vitamin D insufficiency causes calcium dysregulation and follicular arrest in women with PCOS, which is connected to menstrual irregularities and fertility issues. Studies have connected PCOS metabolic alterations to VDR polymorphisms such as iApa-I, Taq-I, Cdx2, and Fok-I. Insulin resistance is directly related to Vitamin D, is one of the most distinctive characteristics of the PCOS phenotype. Thus, it is suggested that Vitamin D therapy may help PCOS patients with their insulin sensitivity. In addition to insulin resistance, cardiovascular issues are a second metabolic disturbance that PCOS patients with low Vitamin D levels experience. Dyslipidemia is not linked to an increased risk of cardiovascular disease in PCOS-affected women. Vitamin D dramatically improves glucose metabolism by increasing insulin production, insulin receptor expression and reducing pro-inflammatory cytokines. The effect of Vitamin D on the metabolic and reproductive dysfunctions associated with PCOS may be mediated by an overall impact on insulin resistance. Vitamin D supplementation improved menstrual periods, increased folliculogenesis, and decreased blood testosterone levels in PCOS patients, all of which had a significant impact on the ability to procreate. As a result, it might be a cutting-edge therapeutic strategy for treating PCOS concurrently.

    目的:在普通人群中,月经异常和生殖寿命缩短与预期寿命缩短以及心血管疾病和骨质疏松症风险增加有关。尽管女性CKD患者中这些生殖因素不规则的程度尚不清楚。本系统综述和荟萃分析旨在总结CKD女性有关月经异常和生殖寿命的最新知识。
    方法:全面的书目搜索(MEDLINE,Embase,和护理和相关健康文献的累积指数[CINAHL])从数据库开始到2022年2月完成,以确定所有报告非透析依赖性/非肾脏移植CKD的育龄女性的原始文章,透析依赖性CKD,或者肾移植和月经模式,初潮年龄,和/或更年期。数据提取和研究质量评估一式两份完成。随机效应荟萃分析用于得出合并比例估计值。
    结果:确定了46项研究,35人进行了荟萃分析,按KRT模式分层并报告结果。19%-47%的血液透析患者和75%的腹膜透析患者存在月经异常。肾移植与月经异常减少7%-30%有关。生殖寿命为32年(95%置信区间,30至34岁)。尽管存在显著的异质性,学习质量从一般到良好,没有发现发表偏倚的证据.
    结论:月经异常和较短的生殖寿命在女性CKD患者中很常见,虽然肾移植可以改善月经健康。
    Menstrual abnormalities and shortened reproductive lifespan are associated with shorter life expectancy and higher cardiovascular and osteoporosis risk in the general population, although the magnitude of these reproductive factor irregularities in females with CKD is unclear. This systematic review and meta-analysis aimed to summarize the current knowledge regarding menstrual abnormalities and reproductive lifespan among females with CKD.
    A comprehensive bibliographic search (MEDLINE, Embase, and Cumulative Index to Nursing and Allied Health Literature [CINAHL]) was completed from database inception to February 2022 to identify all original articles reporting on females of reproductive age with nondialysis-dependent/nonkidney transplant CKD, dialysis-dependent CKD, or kidney transplantation and menstruation patterns, age of menarche, and/or menopause. Data extraction and study quality assessment were completed in duplicate. Random effects meta-analyses were used to derive pooled proportions estimates.
    Forty-six studies were identified, and 35 were meta-analyzed, stratified by KRT modality and reported outcome. Menstrual abnormalities were present in 19%-47% of patients on hemodialysis and 75% of patients on peritoneal dialysis. Kidney transplantation was associated with a 7%-30% decrease in menstrual abnormalities. Reproductive lifespan was 32 years (95% confidence interval, 30 to 34 years). Although significant heterogeneity was present, study quality ranged from fair to good, and no evidence of publication bias was noted.
    Menstrual abnormalities and shorter reproductive lifespan are common in females with CKD, although kidney transplantation may improve menstrual health.

    Isotretinoin (13-cis-retinoic acid), a derivative of vitamin A, is used in the treatment of severe acne resulting in sebum suppression induced by sebocyte apoptosis. Isotretinoin treatment is associated with several adverse effects including teratogenicity, hepatotoxicity, and dyslipidemia. Isotretinoin\'s effects on endocrine systems and its potential role as an endocrine disruptor are not yet adequately investigated. This review presents clinical, endocrine, and molecular evidence showing that isotretinoin treatment adversely affects the pituitary-ovarian axis and enhances the risk of granulosa cell apoptosis reducing follicular reserve. Isotretinoin is associated with pro-apoptotic signaling in sebaceous glands through upregulated expression of p53, forkhead box O transcription factors (FOXO1, FOXO3), and tumor necrosis factor-related apoptosis inducing ligand (TRAIL). Two literature searches including clinical and experimental studies respectively support the hypothesis that isotretinoin\'s toxicological mode of action on the pituitary-ovarian axis might be caused by over-expressed p53/FOXO1 signaling resulting in gonadotropin suppression and granulosa cell apoptosis. The reduction of follicular reserve by isotretinoin treatment should be especially considered when this drug will be administered for the treatment of acne in post-adolescent women, in whom fertility may be adversely affected. In contrast, isotretinoin treatment may exert beneficial effects in states of hyperandrogenism, especially in patients with polycystic ovary syndrome.

    已提出腹腔镜Roux-en-Y胃旁路术(LRYGB)和腹腔镜垂直袖状胃切除术(LVSG)作为管理肥胖相关慢性疾病的经济有效策略。这项系统评价的目的是研究同行评价文献,有关比较LVSG和LRYGB手术的随机对照试验(RCTs)报告的术后非糖尿病合并症疾病缓解或改善。
    RCT比较术后合并疾病的分辨率,如高血压,血脂异常,阻塞性睡眠呼吸暂停,关节和肌肉骨骼状况,胃食管反流病,纳入LVSG和LRYGB后的月经不调进行分析.这些研究选自PubMed,Medline,EMBASE,科学引文索引,当前内容,和Cochrane数据库,并报告了至少一种合并症的解决或改善。本工作是根据系统审查和荟萃分析(PRISMA)的首选报告项目进行的。将Jadad方法用于评估方法学质量。
    在2005年至2015年期间进行了6项RCT,共695名患者(LVSGn=347,LRYGBn=348)报告了LVSG和LRYGB手术后共病的消退或改善。两种减肥方法在改善或解决这些合并症方面都提供了有效且几乎可比的结果。
    这项对RCTs的系统评价表明,LVSG和LRYGB均可有效解决或改善肥胖患者术前的非糖尿病合并症。虽然目前的结果还没有定论,与LVSG相比,LRYGB在调节某些疾病如血脂异常和关节炎的缓解和/或改善方面可能提供更好的结果。
    Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG) have been proposed as cost-effective strategies to manage obesity-related chronic disease. The aim of this systematic review was to study the peer review literature regarding postoperative nondiabetic comorbid disease resolution or improvement reported from randomized controlled trials (RCTs) comparing LVSG and LRYGB procedures.
    RCTs comparing postoperative comorbid disease resolution such as hypertension, dyslipidemia, obstructive sleep apnea, joint and musculoskeletal conditions, gastroesophageal reflux disease, and menstrual irregularities following LVSG and LRYGB were included for analysis. The studies were selected from PubMed, Medline, EMBASE, Science Citation Index, Current Contents, and the Cochrane database and reported on at least one comorbidity resolution or improvement. The present work was undertaken according to the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA). The Jadad method for assessment of methodological quality was applied to the included studies.
    Six RCTs performed between 2005 and 2015 involving a total of 695 patients (LVSG n = 347, LRYGB n = 348) reported on the resolution or improvement of comorbid disease following LVSG and LRYGB procedures. Both bariatric procedures provide effective and almost comparable results in improving or resolving these comorbidities.
    This systematic review of RCTs suggests that both LVSG and LRYGB are effective in resolving or improving preoperative nondiabetic comorbid diseases in obese patients. While results are not conclusive at this time, LRYGB may provide superior results compared to LVSG in mediating the remission and/or improvement in some conditions such as dyslipidemia and arthritis.
