Purpose: This review aims to provide updated information regarding the role of thyroid and leptin hormones and their crosstalk in affecting the male reproductive function in hypothyroid and obesity conditions.

Method: A wide literature search was made using online search engines on published articles using keywords including thyroid hormone, hypothyroidism, leptin hormone, hyperleptinemia, obesity, the relationship between thyroid and leptin hormones and male reproduction, and hypothyroidism, obesity, and male reproduction.

Results: All information pertaining thyroid and leptin hormone effects on male reproduction, hypothyroidism, hyperleptinemia, and obesity effect on male fertility as well as the related molecular mechanisms are obtained.

Conclusion: Thyroid and leptin hormones individually play a significant role in male reproduction. Alterations of these hormones' levels could adversely affect the male reproductive functions. PI3K/AKT signaling was found to be the major signaling pathway involved in mediating the effect of both hormones on male reproduction. Impaired crosstalk between the two hormones may occur in hypothyroidism with obesity which would contribute towards male reproductive dysfunction.

目的:本综述旨在提供有关甲状腺激素和瘦素激素的作用及其在甲状腺功能减退症和肥胖症中影响男性生殖功能的相互关系的最新信息:利用在线搜索引擎对已发表的文章进行了广泛的文献检索,关键词包括甲状腺激素、甲状腺功能减退症、瘦素激素、高瘦血症、肥胖症、甲状腺和瘦素激素与男性生殖的关系、甲状腺功能减退症、肥胖症和男性生殖:结果:获得了有关甲状腺和瘦素激素对男性生殖的影响、甲状腺功能减退症、高瘦血症和肥胖症对男性生育能力的影响以及相关分子机制的所有信息:结论:甲状腺激素和瘦素激素在男性生殖过程中发挥着重要作用。结论:甲状腺激素和瘦素激素在男性生殖过程中发挥着重要作用,这些激素水平的变化会对男性生殖功能产生不利影响。研究发现,PI3K/AKT 信号传导是介导这两种激素对男性生殖功能影响的主要信号传导途径。在甲状腺功能减退症合并肥胖症时,这两种激素之间的串扰可能会受损,从而导致男性生殖功能障碍。

Background: Diabetic ketoacidosis (DKA) is often treated with intravenous regular insulin infusion (IVRII). Subcutaneous fast-acting insulin analogues (FAIAs); either alone or combined with subcutaneous long-acting insulin (LAI); might be useful to treat DKA. Our meta-analysis updated on their benefits and safety in DKA.

Methods: We searched major electronic databases for randomised trials on subcutaneous FAIAs ± subcutaneous LAI vs IVRII in DKA. Primary outcomes were all-cause in-hospital mortality, time to resolution of DKA and hyperglycemia, in-hospital DKA recurrence and hospital readmission for DKA post-discharge. Secondary outcomes included resource utilisation and patient satisfaction. Safety outcomes were adverse events. Reviewers assessed risk of bias and quality of evidence using GRADE. We performed a priori subgroup and trial sequential analyses on primary outcomes.

Results: Seven trials enrolled 351 mainly adult patients (255/351) with mild to moderate DKA. No trials studied subcutaneous FAIA and subcutaneous LAI. Their risk of bias was high or unclear in several domains. No all-cause in-hospital mortality and DKA recurrence were reported. No trial investigated hospital readmission for DKA post-discharge. There was no difference in mean time to resolution of DKA (mean difference = -0.70, 95% CI -2.18 to 0.79 h, p = 0.36) or hyperglycemia [blood glucose < 250 mg/dL (13.9 mmol/L)] (mean difference = -0.17, 95% CI -1.10 to 0.76 h, p = 0.72) between subcutaneous FAIA and IVRII groups. There were largely no subgroup effects. Both groups had similar secondary outcomes. Hypoglycemia was the most common adverse event. Quality of evidence was low to very-low for all outcomes. The only possible trial sequential analysis for time to resolution of DKA was inconclusive.

Conclusions: There was low- to very-low quality evidence that subcutaneous FAIA did not affect patient-centered outcomes in mainly adult patients with mild to moderate DKA compared to IVRII.

背景:糖尿病酮症酸中毒(DKA)通常采用静脉定期输注胰岛素(IVRII)治疗。皮下注射速效胰岛素类似物(FAIAs),无论是单独使用还是与皮下注射长效胰岛素(LAI)联合使用,都可能有助于治疗 DKA。我们的荟萃分析更新了这些药物对 DKA 的益处和安全性:我们在主要电子数据库中搜索了皮下FAIAs±皮下LAI与IVRII治疗DKA的随机试验。主要结果包括全因院内死亡率、DKA 和高血糖缓解时间、院内 DKA 复发率和出院后 DKA 再入院率。次要结果包括资源利用率和患者满意度。安全性结果为不良事件。审稿人使用 GRADE 评估了偏倚风险和证据质量。我们对主要结果进行了先验亚组和试验序列分析:七项试验共招募了351名轻度至中度DKA成人患者(255/351)。没有一项试验研究了皮下 FAIA 和皮下 LAI。这些试验在多个方面的偏倚风险较高或不明确。未报告全因院内死亡率和DKA复发率。没有一项试验调查了出院后因 DKA 再次入院的情况。DKA 的平均缓解时间(平均差异 = -0.70,95% CI -2.18 至 0.79 h,p = 0.36)或高血糖[血糖结论]没有差异:低质量到极低质量的证据表明,与 IVRII 相比,皮下 FAIA 不会影响以患者为中心的预后,主要是轻度到中度 DKA 的成年患者。

Diabetes mellitus (DM) is a complex metabolic disorder characterized by chronic hyperglycemia, which derives from either insufficient insulin production [type 1 diabetes mellitus (T1DM)] or both impaired insulin sensitivity along with inadequate insulin production [type 2 diabetes mellitus (T2DM)] and affects millions of people worldwide. In addition to the adverse effects of DM on classical target organs and tissues, skeletal health can also be adversely affected. There is considerable evidence linking DM with osteoporosis. The fracture risk in patients with DM differs upon the type of diabetes, and it appears to be related to the type of anti-diabetic treatment. Antidiabetic drugs may have various effects on bone health. Most of them have neutral or even favorable effects on bone metabolism with the exception of thiazolidinediones (TZDs). Some studies suggest that TZDs may have negative impact on bone health by decreasing bone formation and increasing the fracture risk. There are also limited studies linking the use of canagliflozin, a Sodium-glucose contransporter-2 inhibitor (SGLT2i), with increased fracture risk. On the other hand, therapies that are based on incretin effect, like Dipeptidyl peptidase-4 inhibitors (DPP-4i) and Glucagon-like peptide-1 receptor agonizts (GLP-1RAs) might have positive effects on bone health by promoting bone formation. Herein we review the impact of antidiabetic drugs on bone health, highlighting the potential benefits and risks associated with these medications in an attempt to contribute to the development of personalized treatment strategies for individuals with DM.

糖尿病(DM)是一种以慢性高血糖为特征的复杂代谢性疾病,其原因是胰岛素分泌不足[1 型糖尿病(T1DM)]或胰岛素敏感性受损同时胰岛素分泌不足[2 型糖尿病(T2DM)],影响着全球数百万人。糖尿病除了对传统的目标器官和组织产生不利影响外,还可能对骨骼健康产生不利影响。有大量证据表明,糖尿病与骨质疏松症有关。糖尿病患者骨折的风险因糖尿病类型而异,而且似乎与抗糖尿病治疗的类型有关。抗糖尿病药物可能会对骨骼健康产生各种影响。除噻唑烷二酮类药物(TZDs)外,大多数药物对骨代谢的影响为中性甚至有利。一些研究表明,噻唑烷二酮类药物可能会减少骨形成并增加骨折风险,从而对骨骼健康产生负面影响。还有一些有限的研究表明,使用钠-葡萄糖转运体-2 抑制剂(SGLT2i)卡格列净(canagliflozin)会增加骨折风险。另一方面,基于增量素效应的疗法,如二肽基肽酶-4 抑制剂(DPP-4i)和胰高血糖素样肽-1 受体激动剂(GLP-1RA),可能会通过促进骨形成而对骨骼健康产生积极影响。在此,我们回顾了抗糖尿病药物对骨骼健康的影响,强调了与这些药物相关的潜在益处和风险,试图为制定针对糖尿病患者的个性化治疗策略做出贡献。

Purpose: Cardiometabolic disorders are non-classical complications of hypercalcemic primary hyperparathyroidism (HC-PHPT), but whether this risk connotes normocalcemic PHPT (NC-PHPT) remains to be elucidated. We investigated cardiometabolic alterations in both forms of PHPT, looking for their association with indices of disease activity.

Methods: Patients with HC-PHPT (n = 17), NC-PHPT (n = 17), and controls (n = 34) matched for age, sex, and BMI were assessed for glucose, lipid, blood pressure alterations, and history of cardiovascular events to perform a case-control study at an ambulatory referral center for Bone Metabolism Diseases.

Results: NC-PHPT, in comparison to controls, showed similar glucose (mean ± SD, 88 ± 11 vs 95 ± 22 mg/dl), total cholesterol (199 ± 25 vs 207 ± 36 mg/dl), and systolic blood pressure levels (SBP, 132 ± 23 vs 132 ± 19 mmHg), together with a comparable frequency of glucose alterations (6% vs 9%), lipid disorders (41% vs 50%) and hypertension (53% vs 59%, p = NS for all comparisons). Conversely, all these abnormalities were more prevalent in HC-PHPT vs controls (p < 0.05). When compared to NC-PHPT, HC-PHPT showed higher glucose (113 ± 31 mg/dl), total cholesterol (238 ± 43 mg/dl), and SBP levels (147 ± 15 mmHg) as well as an increased frequency of glucose (41%) and lipid alterations (77%) and a higher number of cardiovascular events (18% vs 0%, p < 0.05 for all comparisons). Among indices of PHPT activity, calcium levels displayed a significant correlation with glucose (R = 0.46) and SBP values (R = 0.60, p < 0.05).

Conclusion: NC-PHPT is not associated with cardiovascular alterations. The predominant pathogenetic role of hypercalcemia in the development of cardiometabolic disorders could account for the absence of such alterations in NC-PHPT.

目的:心脏代谢紊乱是高钙血症性原发性甲状旁腺功能亢进症(HC-PHPT)的非典型并发症,但这种风险是否意味着正常钙血症性原发性甲状旁腺功能亢进症(NC-PHPT)仍有待阐明。我们研究了这两种形式的PHPT的心脏代谢变化,寻找它们与疾病活动性指数之间的关联:方法:我们在骨代谢疾病门诊转诊中心对HC-PHPT(17例)、NC-PHPT(17例)患者和年龄、性别、体重指数相匹配的对照组(34例)进行了血糖、血脂、血压变化和心血管事件史评估,以开展一项病例对照研究:结果:与对照组相比,NC-PHPT 患者的血糖(平均±标准差,88±11 vs 95±22 mg/dl)、总胆固醇(199±25 vs 207±36 mg/dl)和收缩压水平(SBP,132±23 vs 132±19 mmHg)相似,血糖变化(6% vs 9%)、血脂紊乱(41% vs 50%)和高血压(53% vs 59%,所有比较中 p = NS)的发生频率也相当。相反,所有这些异常在 HC-PHPT 与对照组中的发生率更高(p 结论:NC-PHPT 与血糖变化无关:NC-PHPT与心血管改变无关。高钙血症在心血管代谢紊乱的发展过程中起着主要的致病作用,这可能是 NC-PHPT 中没有此类改变的原因。

Objective: Polycystic Ovarian Syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age. Several candidate genes have been shown to be associated with PCOS. Previous studies have shown that variations in CYP11A1 and CYP19A1 genes are associated with hormonal dysregulation associated with PCOS in different ethnic populations. This study aims to investigate the genomic association between SNPs rs4077582 of CYP11A1 and rs700519 of CYP19A1 and the development of PCOS in Pakistani population.

Methods: A total of 280 subjects were recruited for the study, including 142 PCOS cases diagnosed based on Rotterdam criteria and 138 age-matched controls. The anthropometric, hormonal and biochemical parameters of all subjects were analyzed. Genomic DNA was extracted and genotyping of the selected SNPs was performed using Sanger sequencing. Further, we also examined the genotypic-phenotypic correlation analysis for various clinical and biochemical parameters for SNP rs4077582 of CYP11A1.

Results: We found significant differences in allele frequency (OR = 0.42, 95% CI = 0.30-0.60, χ2 = 16.3693, p = 0.000052) and genotypic frequency (χ2 = 26.4376, p = 0.00001) between PCOS women and controls for SNP rs4077582 of CYP11A1. Genotype-phenotype correlation analysis showed a significant difference in FAI (p = 0.005), testosterone (p = 0.001), androstenedione (p = 0.005) and urea (p = 0.049) levels between the three genotypes. No association between SNP rs700519 of CYP19A1 and PCOS was observed.

Conclusion: Our results suggest the role of SNP rs4077582 of CYP11A1 gene in the clinical manifestation of PCOS in Pakistani women.

目的:多囊卵巢综合征(PCOS)是一种影响育龄妇女的复杂内分泌疾病。有多个候选基因被证明与多囊卵巢综合症有关。先前的研究表明,在不同种族人群中,CYP11A1 和 CYP19A1 基因的变异与多囊卵巢综合征相关的激素失调有关。本研究旨在调查巴基斯坦人群中 CYP11A1 的 SNPs rs4077582 和 CYP19A1 的 SNPs rs700519 与 PCOS 发病之间的基因组关联:研究共招募了 280 名受试者,包括 142 名根据鹿特丹标准确诊的多囊卵巢综合征病例和 138 名年龄匹配的对照组。对所有受试者的人体测量、激素和生化参数进行了分析。我们提取了基因组 DNA,并使用 Sanger 测序法对所选 SNPs 进行了基因分型。此外,我们还研究了 CYP11A1 SNP rs4077582 的各种临床和生化指标的基因型与表型相关性分析:我们发现CYP11A1的SNP rs4077582的等位基因频率(OR = 0.42, 95% CI = 0.30-0.60, χ2 = 16.3693, p = 0.000052)和基因型频率(χ2 = 26.4376, p = 0.00001)在PCOS女性和对照组之间存在明显差异。基因型-表型相关分析表明,三种基因型之间的 FAI(p = 0.005)、睾酮(p = 0.001)、雄二酮(p = 0.005)和尿素(p = 0.049)水平存在显著差异。CYP19A1的SNP rs700519与多囊卵巢综合征之间没有关联:我们的研究结果表明,CYP11A1 基因的 SNP rs4077582 在巴基斯坦女性多囊卵巢综合征的临床表现中起着重要作用。

Papillary thyroid cancer (PTC) is the predominant form of malignant tumor affecting the thyroid gland.

Aim: This study aimed to identify candidate biomarkers for papillary thyroid carcinoma using an integrative analysis of bioinformatics and machine learning (ML).

Material and method: The PTC datasets GSE6004, GSE3467, and GSE33630 (species: Homo sapiens) were downloaded from NCBI and analyzed using the limma package to obtain DEGs. Once DEGs were identified, GO and KEGG enrichment analyses were performed as the first step in the bioinformatics process. Subsequently, a protein-protein interaction (PPI) network was constructed according to the common genes in bioinformatics and machine learning using STRING to elucidate the important genes involved in PTC pathogenesis. In machine learning, finding genes entails feature selection to identify the key genes that distinguish biological states. Hybrid feature selection will be used for this. In the second step, the original data sets were preprocessed to detect and correct missing and noisy data; after that, all data were merged. Following performing Linear and Discriminative Hybrid Feature Selection (LDHFS) on the processed dataset, machine learning algorithms such as Random Forest (RF), Naive Bayes (NB), and Support Vector Machines (SVM) are utilized.

Results: Bioinformatics and machine learning analyses indicate that the genes RXRG, CDH2, ETV5, QPCT, LRP4, FN1, and LPAR5 are integral to the progression of thyroid cancer. This study attained the highest accuracy utilizing the RF algorithm, achieving an accuracy rate of 94.62%, a Kappa value of 91.36%, and an AUC value of 96.13%. These results offer additional evidence and confirmation for the genetic alterations of these genes. These findings may accelerate the development of prospective therapeutic and diagnostic methods in future research.

Conclusions: Bioinformatics and machine learning techniques identified the common genes "RXRG, CDH2, ETV5, QPCT, LRP4, FN1, and LPAR5" as PTC biomarkers, providing novel reference markers for the diagnosis and treatment of PTC patients. The model is anticipated to possess significant predictive value and assist in the early diagnosis and screening of clinical PTC. These insights enhance the field of PTC management and offer guidance for future research.

甲状腺乳头状癌(PTC)是影响甲状腺的主要恶性肿瘤形式。目的:本研究旨在利用生物信息学和机器学习(ML)的综合分析方法确定甲状腺乳头状癌的候选生物标志物:从NCBI下载PTC数据集GSE6004、GSE3467和GSE33630(物种:智人),并使用limma软件包进行分析以获得DEGs。确定 DEGs 后,生物信息学流程的第一步是进行 GO 和 KEGG 富集分析。随后,根据生物信息学和机器学习中的常见基因,利用 STRING 构建了蛋白质-蛋白质相互作用(PPI)网络,以阐明参与 PTC 发病机制的重要基因。在机器学习中,寻找基因需要进行特征选择,以确定区分生物状态的关键基因。为此将使用混合特征选择。第二步,对原始数据集进行预处理,以检测和纠正缺失数据和噪声数据;然后,合并所有数据。在对处理后的数据集进行线性和判别混合特征选择(LDHFS)后,使用随机森林(RF)、奈夫贝叶斯(NB)和支持向量机(SVM)等机器学习算法:生物信息学和机器学习分析表明,RXRG、CDH2、ETV5、QPCT、LRP4、FN1 和 LPAR5 基因与甲状腺癌的进展密切相关。这项研究利用 RF 算法达到了最高的准确率,准确率为 94.62%,Kappa 值为 91.36%,AUC 值为 96.13%。这些结果为这些基因的遗传改变提供了更多的证据和确认。这些发现可能会加速未来研究中前瞻性治疗和诊断方法的开发:生物信息学和机器学习技术确定了 "RXRG、CDH2、ETV5、QPCT、LRP4、FN1 和 LPAR5 "等常见基因为 PTC 生物标记物,为 PTC 患者的诊断和治疗提供了新的参考标记。预计该模型将具有重要的预测价值,有助于临床 PTC 的早期诊断和筛查。这些见解将促进 PTC 管理领域的发展,并为未来的研究提供指导。

Background: Hypoparathyroidism is a rare endocrine disease characterized by insufficient parathyroid hormone (PTH) secretion by the parathyroid glands, leading to hypocalcemia. In contrast to most hormone deficiencies for which hormone replacement is currently the mainstay of therapy, hypoparathyroidism has conventionally been treated with calcium supplements and active analogs of vitamin D. Although the advent of a replacement therapy with 1-34 and 1-84 PTH represented a major step in the therapeutic history of hypoparathyroidism, several new molecules and different management strategies have recently been developed.

Purpose: This review investigates the therapeutic approaches currently under investigation for the treatment of hypoparathyroidism. Clinical trials results have been considered and discussed.

背景:甲状旁腺功能减退症是一种罕见的内分泌疾病,其特点是甲状旁腺分泌的甲状旁腺激素(PTH)不足,从而导致低钙血症。虽然1-34和1-84 PTH替代疗法的出现是甲状旁腺功能减退症治疗史上的重要一步,但最近又开发出了几种新的分子和不同的治疗策略。目的:本综述探讨了目前正在研究的治疗甲状旁腺功能减退症的方法。其中还考虑并讨论了临床试验结果。

Purpose: Large language models (LLMs) are pivotal in artificial intelligence, demonstrating advanced capabilities in natural language understanding and multimodal interactions, with significant potential in medical applications. This study explores the feasibility and efficacy of LLMs, specifically ChatGPT-4o and Claude 3-Opus, in classifying thyroid nodules using ultrasound images.

Methods: This study included 112 patients with a total of 116 thyroid nodules, comprising 75 benign and 41 malignant cases. Ultrasound images of these nodules were analyzed using ChatGPT-4o and Claude 3-Opus to diagnose the benign or malignant nature of the nodules. An independent evaluation by a junior radiologist was also conducted. Diagnostic performance was assessed using Cohen's Kappa and receiver operating characteristic (ROC) curve analysis, referencing pathological diagnoses.

Results: ChatGPT-4o demonstrated poor agreement with pathological results (Kappa = 0.116), while Claude 3-Opus showed even lower agreement (Kappa = 0.034). The junior radiologist exhibited moderate agreement (Kappa = 0.450). ChatGPT-4o achieved an area under the ROC curve (AUC) of 57.0% (95% CI: 48.6-65.5%), slightly outperforming Claude 3-Opus (AUC of 52.0%, 95% CI: 43.2-60.9%). In contrast, the junior radiologist achieved a significantly higher AUC of 72.4% (95% CI: 63.7-81.1%). The unnecessary biopsy rates were 41.4% for ChatGPT-4o, 43.1% for Claude 3-Opus, and 12.1% for the junior radiologist.

Conclusion: While LLMs such as ChatGPT-4o and Claude 3-Opus show promise for future applications in medical imaging, their current use in clinical diagnostics should be approached cautiously due to their limited accuracy.

目的:大型语言模型(LLMs)在人工智能领域举足轻重,在自然语言理解和多模态交互方面表现出先进的能力,在医疗应用方面具有巨大潜力。本研究探讨了大型语言模型(特别是 ChatGPT-4o 和 Claude 3-Opus)使用超声图像对甲状腺结节进行分类的可行性和有效性:这项研究包括 112 名甲状腺结节患者,共 116 个甲状腺结节,其中包括 75 个良性病例和 41 个恶性病例。使用 ChatGPT-4o 和 Claude 3-Opus 对这些结节的超声图像进行分析,以诊断结节的良性或恶性。一名初级放射科医生也进行了独立评估。参考病理诊断结果,使用科恩卡帕和接收器操作特征曲线(ROC)分析评估诊断性能:ChatGPT-4o 与病理结果的一致性较差(Kappa = 0.116),而克劳德 3-Opus 的一致性更低(Kappa = 0.034)。而初级放射科医生的吻合度为中等(Kappa = 0.450)。ChatGPT-4o 的 ROC 曲线下面积(AUC)为 57.0%(95% CI:48.6-65.5%),略高于 Claude 3-Opus(AUC 为 52.0%,95% CI:43.2-60.9%)。相比之下,初级放射医师的 AUC 明显更高,达到 72.4%(95% CI:63.7-81.1%)。ChatGPT-4o 的不必要活检率为 41.4%,Claude 3-Opus 为 43.1%,而初级放射医师为 12.1%:结论:虽然 ChatGPT-4o 和 Claude 3-Opus 等 LLM 在医学影像领域的应用前景广阔,但由于其准确性有限,目前在临床诊断中的使用仍需谨慎。

Radioligand therapy in sympathetic-adrenal-medullary axis tumors: state of art and perspectives. 交感-肾上腺-髓质轴肿瘤的放射性配体疗法:技术现状与前景。

The approval in 2017 by the European Medicines Agency (EMA) and in 2018 by the US Food and Drug Administration (FDA) of radioligand therapy (RLT) led to its wide application in therapeutic management of neuroendocrine neoplasms (NENs). However, the indications are currently limited to certain specific histotypes belonging to the broader NEN's family, mainly advanced well-differentiated gastro-entero-pancreatic NENs. As a consequence, several other tumors of the NEN spectrum that can potentially benefit, due to their biological characteristics, from RLT are still ineligible and can be considered "RLT-orphans". Among those, the subgroup of NENs originating from the sympathetic-adrenal-medullary (SAM) axis can be listed. This paper discusses the state of art and perspectives of the theragnostic applications in pheochromocytomas and paragangliomas, considering both the traditional theragnostic model - with radiolabelled metaiodobenzylguanidine (MIBG) - and the innovative one with radiolabeled somatostatin analogs (SSAs), that will hopefully become available for these patients in the near future.

放射配体疗法(RLT)于2017年获得欧洲药品管理局(EMA)批准,2018年获得美国食品药品管理局(FDA)批准,从而被广泛应用于神经内分泌肿瘤(NENs)的治疗管理。不过,目前的适应症仅限于属于更广泛的神经内分泌肿瘤家族的某些特定组织类型,主要是晚期分化良好的胃肠胰腺神经内分泌肿瘤。因此,NEN谱系中其他几种因其生物学特征而有可能从RLT中获益的肿瘤仍不符合条件,可被视为 "RLT-orphans"。在这些肿瘤中,源自交感-肾上腺-髓质(SAM)轴的 NENs 亚群可以列入其中。本文讨论了嗜铬细胞瘤和副神经节瘤的放射治疗应用现状和前景,既考虑了传统的放射治疗模式(使用放射性标记的偏碘苄基胍(MIBG)),也考虑了使用放射性标记的体生长激素类似物(SSA)的创新模式,希望在不久的将来这些患者也能使用这种治疗方法。

Purpose: α-Klotho has been linked to insulin resistance (IR) in basic research. However, experimental evidence is inconsistent, and there is a lack of data from human research. This study seeks to elucidate the association of α-Klotho with IR in a nationwide, multiracial population.

Methods: A total of 5289 participants aged 40-79 years were included in the National Health and Nutrition Examination Survey (NHANES) spanning 2007-2016. Serum α-Klotho was measured using enzyme-linked immunosorbent assays (ELISA), and IR was evaluated by the homeostatic model assessment of insulin resistance (HOMA-IR). Weighted multivariate logistic and linear regression analysis, subgroup analysis stratified by demographic characteristics, medical condition or obesity status, and sensitivity analysis using propensity score matching (PSM) were performed. Restricted cubic splines (RCS) were performed to explore the nonlinear relationship.

Results: In the fully adjusted logistic regression model, a significant positive association was observed between log-transformed α-Klotho and IR (OR = 3.63, 95% CI: 1.56, 8.45), particularly in males or nonobese individuals (Pinteraction < 0.05). In the linear regression model, log10(α-Klotho) was associated with fasting blood glucose (FBG, β = 1.25, 95% CI: 0.74, 1.76) and glycosylated hemoglobin (HbA1c, β = 0.49, 95% CI: 0.20, 0.77). RCS revealed an inverse L-shaped dose-response relationship of α-Klotho with FBG and HbA1c (Pnonlinear <0.05). Beyond the inflection point of log10(α-Klotho) at 2.79, β coefficients sharply rose for these glycaemic control indicators.

Conclusion: The study provides clinical evidence supporting a positive association between α-Klotho and IR. Moreover, the inverse L-shaped relationship suggests that α-Klotho should reach a certain level to predict glycaemic changes effectively.

目的:在基础研究中,α-Klotho 与胰岛素抵抗(IR)有关。然而,实验证据并不一致,也缺乏人体研究数据。本研究试图在全国范围内的多种族人群中阐明α-Klotho与IR的关系:方法:在 2007-2016 年的美国国家健康与营养调查(NHANES)中,共纳入了 5289 名 40-79 岁的参与者。血清α-Klotho采用酶联免疫吸附测定法(ELISA)进行测定,IR采用胰岛素抵抗同态模型评估法(HOMA-IR)进行评估。研究人员进行了加权多变量逻辑和线性回归分析、按人口统计学特征、医疗状况或肥胖状况分层的亚组分析,以及使用倾向得分匹配法(PSM)进行的敏感性分析。为探讨非线性关系,还进行了限制性三次样条(RCS)分析:结果:在完全调整的逻辑回归模型中,观察到对数变换后的α-Klotho与IR之间存在显著的正相关(OR = 3.63,95% CI:1.56, 8.45),尤其是男性或女性。10(α-Klotho)与空腹血糖(FBG,β = 1.25,95% CI:0.74,1.76)和糖化血红蛋白(HbA1c,β = 0.49,95% CI:0.20,0.77)相关。RCS显示,α-Klotho与FBG和HbA1c呈反L型剂量反应关系(Pnonlinear 10(α-Klotho)为2.79,这些血糖控制指标的β系数急剧上升):结论:本研究提供的临床证据支持α-Klotho 与 IR 之间存在正相关。此外,反 L 型关系表明,α-Klotho 应达到一定水平才能有效预测血糖变化。

Moreover, the inverse L-shaped relationship suggests that α-Klotho should reach a certain level to predict glycaemic changes effectively.</p>","PeriodicalId":49211,"journal":{"name":"Endocrine","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140960358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
