RESUMO

BACKGROUND: To compare the ability of the Cox regression and machine learning algorithms to predict the survival of patients with Anaplastic thyroid carcinoma (ATC). METHODS: Patients diagnosed with ATC were extracted from the Surveillance, Epidemiology, and End Results database. The outcomes were overall survival (OS) and cancer-specific survival (CSS), divided into: (1) binary data: survival or not at 6 months and 1 year; (2): time-to-event data. The Cox regression method and machine learnings were used to construct models. Model performance was evaluated using the concordance index (C-index), brier score and calibration curves. The SHapley Additive exPlanations (SHAP) method was deployed to interpret the results of machine learning models. RESULTS: For binary outcomes, the Logistic algorithm performed best in the prediction of 6-month OS, 12-month OS, 6-month CSS, and 12-month CSS (C-index = 0.790, 0.811, 0.775, 0.768). For time-event outcomes, traditional Cox regression exhibited good performances (OS: C-index = 0.713; CSS: C-index = 0.712). The DeepSurv algorithm performed the best in the training set (OS: C-index = 0.945; CSS: C-index = 0.834) but performs poorly in the verification set (OS: C-index = 0.658; CSS: C-index = 0.676). The brier score and calibration curve showed favorable consistency between the predicted and actual survival. The SHAP values was deployed to explain the best machine learning prediction model. CONCLUSIONS: Cox regression and machine learning models combined with the SHAP method can predict the prognosis of ATC patients in clinical practice. However, due to the small sample size and lack of external validation, our findings should be interpreted with caution.

RESUMO

OBJECTIVES: Systemic lupus erythematosus (SLE) is an autoimmune disease characterised by immune inflammation. It involves multiple organs. Many studies have demonstrated that circRNAs are closely associated with SLE. Nonetheless, the potential mechanism by which circRNAs impacts SLE is not fully understood. The aim of this study was to explore the regulatory roles of circRNAs, the key genes and pathways governing the pathophysiological processes of SLE, and to screen therapeutic agents. METHODS: The sequencing data of circRNA, miRNA and mRNA were obtained from Gene Expression Omnibus (GEO) datasets. Candidates were identified to construct a circRNA-miRNA-mRNA network based on circRNA-miRNA interactions and miRNA-mRNA interactions. Gene functional enrichments were performed on the DAVID database. Protein-protein interaction (PPI) network was constructed by STRING database and visualised in Cytoscape software. The hub genes were explored by the MCODE plugin app. The Connectivity Map L1000 platform was used to identify potential agents. RESULTS: A total of 1093 differentially expressed circRNAs (DEcircRNAs), 42 differentially expressed miRNAs (DEmiRNAs) and 1431 differentially expressed mRNAs (DEmRNAs) were identified. We integrated 3 overlapped circRNAs, 13 miRNAs and 352 target mRNAs into a circRNA-miRNA-mRNA network. We next identified 44 hub genes based on the PPI network. KEGG pathway analysis revealed that the DEGs were mainly associated with MAPK signalling pathway. In addition, we discovered several chemicals as potential treatment options for SLE. CONCLUSIONS: Through this bioinformatics analysis, we suggest a regulatory role for circRNAs in the pathogenesis and treatment of SLE from the view of a competitive endogenous RNA (ceRNA) network.

RESUMO

BACKGROUND AND AIMS: Previous studies had shed a new light on the importance of multiple inflammatory mechanisms in the pathogenesis of arterial stiffness. The dietary inflammatory index (DII®) is a new tool for estimating the overall inflammatory potential of the diet. The aim of this study is to assess the association of the inflammatory potential of diet with peripheral arterial stiffness and renal function in women with diabetes and prediabetes. METHODS AND RESULTS: This is an observational cross-sectional study. A total of 2644 females aged 45-75 years were included for the study. Dietary intake in the past 12 months was assessed by a validated China National Nutrition and Health Survey 2002 (CNHS2002) food-frequency questionnaire. Energy-adjusted DII (E-DII) scores were calculated from daily dietary information. In a multivariable linear regression analysis adjusted for potential confounders, E-DII was positively associated with brachial ankle pulse wave velocity (baPWV) in participants with diabetes (ß = 12.820; 95% CI = 2.565, 23.076; P = 0.014) and prediabetes (ß = 29.025; 95% CI = 1.110, 56.940; P = 0.042), but not in females with normal glucose homeostasis. In addition, per unit increase of E-DII was significantly associated with lower eGFR (ß = -1.363; 95% CI = -2.335, -0.392; P = 0.006) in patients with diabetes. CONCLUSION: We identified a direct association between E-DII and arterial stiffness, decreasedeGFR in middle-aged and elderly women with diabetes or prediabetes. Future studies are needed to verify and clarify the role of E-DII as an intervention target for cardiorenal complications of chronic hyperglycemia.

RESUMO

PURPOSE: Studies on the effects of I-131 therapy on pregnancy outcomes after differentiated thyroid carcinoma (DTC) surgery showed inconsistent findings. The purpose of the study was to investigate the association between I-131 therapy and pregnancy outcomes in female DTC patients. METHODS: PubMed, Embase, Cochrane Library, CNKI, and VIP were searched until November, 2020. Keywords included differentiated thyroid cancer, thyroid carcinoma, thyroid neoplasm, radioiodine, I-131, 131I, pregnancy outcomes, reproduction, fertility, abortion, preterm birth, and congenital malformation. Studies that provided the pregnancy outcomes in DTC patients who received I-131 therapy and those who did not receive I-131 therapy were included. Meta-analysis was performed in Stata/SE 12. A random or fixed effects model was adopted according to the result of heterogeneity test. RESULTS: Seven observational studies were eligible, involving 125,591 participants and 13,811 pregnancies. It showed that postoperative I-131 therapy for DTC had no significant effect on spontaneous abortion (OR = 1.05, P = 0.701), induced abortion (OR = 1.06, P = 0.859), abortion (OR = 1.07, P = 0.098), premature birth (OR = 1.02, P = 0.756), stillbirth (OR = 1.58, P = 0.364), and congenital malformation(OR = 1.00, P = 0.986). Cumulative RAI dose >3.7 GBq or <3.7 GBq had no significant effect on abortion (OR = 0.94, P = 0.252) and congenital malformation (OR = 1.05, P = 0.752).The group in which interval time between last I-131 therapy and pregnancy >1 year had significant lower risk of abortion than with interval <1 year (OR = 0.60, P = 0.000). CONCLUSIONS: Pregnancy is not recommended for DTC patients within 1 year after I-131 therapy.

RESUMO

Context: Radiotherapy for patients with acromegaly was considered when patients have residual disease or tumor recurrence after surgery, or when surgery can't be carried out. There are two main modes of radiotherapy, including stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (FSRT). Objective: We conducted a systematic review and meta-analysis to present the effectiveness and safety of SRS and FSRT for GH secreting pituitary adenoma in clinical practice. Methods: We searched the published literature using following databases: Pub Med, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and EMBASE up to March 22, 2020, for studies in which SRS or FSRT were used in patients with GH secreting pituitary. Results: A total of 33 studies were eligible, involving 2016 participants. No significant differences were observed in tumor shrinkage rate, local tumor control rate and adverse effect rate between SRS and FSRT. Compared to FSRT, SRS showed significant increase in biochemical remission rate (43% vs. 28%; p=0.023) and significant lower follow-up GH level (SMD: -1.20 vs. -0.37, p=0.006). Conclusions: SRS and FSRT showed comparable effectiveness and safety in the management of GH secreting pituitary adenoma patients. SRS might be associated with better biochemical remission.

RESUMO

Di-(2-ethylhexyl) phthalate (DEHP) is ubiquitous in the environment and has been proposed to lead to reproductive disruption. In this study, we systematically investigated the effects of different doses of DEHP exposure on female hypothalamic-pituitary-gonadal axis development. Female Sprague-Dawley rats were gavaged with vehicle (corn oil) or DEHP (5 or 500mgkg-1 day-1) during postnatal Days (PNDs) 22-28 or PNDs 22-70. Results demonstrated that the low and high doses of DEHP exerted opposite effects on puberty onset, circulating luteinising hormone, serum oestradiol and progesterone levels, with the low dose (5mgkg-1) promoting and the high dose (500mgkg-1) inhibiting these parameters. Significant dose-related differences were also found in the D500 group with longer oestrous cycle duration, lower ovarian/bodyweight ratio, fewer corpus lutea and more abnormal ovarian stromal tissue in comparison with the oil or D5 groups. Molecular data showed that the hypothalamic Kiss1 mRNA expression in the anteroventral periventricular but not in the arcuate nucleus significantly decreased in the D500 rats and increased in the D5 rats relative to the rats in the oil group. These findings suggested that the kisspeptin system is a potential target for DEHP to disrupt reproductive development and function.

RESUMO

OBJECTIVE: To assess the efficacy and safety of prenatal dexamethasone treatment in offspring at risk for congenital adrenal hyperplasia. METHODS: MEDLINE, EMBASE, the Cochrane Library, the clinicaltrials.gov website databases were systematically searched from inception through March 2019. WMD and SMD with 95%CIs were calculated using random or fixed effects models. RESULTS: There was a significant reduction in virilization in the DEX-treated group (WMD: -2.39, 95%CI: -3.31,-1.47). No significant differences were found in newborn physical outcomes for birth weight (WMD: 0.09, 95%CI: -0.09, 0.27) and birth length (WMD = 0.27, 95%CI: -0.68, 1.21). Concerning cognitive functions, no significant differences in the domains of psychometric intelligence (SMD: 0.05, 95%CI: -0.74, 0.83), verbal memory (SMD: -0.17, 95%CI: -0.58, 0.23), visual memory (SMD: 0.10, 95%CI: -0.14, 0.34), learning (SMD: -0.02, 95%CI: -0.27, 0.22) and verbal processing (SMD: -0.38, 95%CI: -0.93, 0.17). Regarding behavioural problems, no significant differences in the domains of internalizing problems (SMD: 0.16, 95%CI: -0.49, 0.81), externalizing problems (SMD: 0.07, 95%CI: -0.30, 0.43) and total problems (SMD: 0.14, 95%CI: -0.23, 0.51). With respect to temperament, no significant differences in the domains of emotionality (SMD: 0.13, 95%CI: -0.79, 1.05), activity (SMD: 0.04, 95%CI: -0.32, 0.39), shyness (SMD: 0.25, 95%CI: -0.70, 1.20) and sociability (SMD: -0.23, 95%CI: -0.90, 0.44). CONCLUSIONS: Prenatal DEX treatment reduced virilization with no significant differences in newborn physical outcomes, cognitive functions, behavioural problems and temperament. The results need to be interpreted cautiously due to the existence of limitations.

RESUMO

BACKGROUND: Thyroid dysfunction is one of the prevalent endocrine disorders. The relationship between lifestyle factors and thyroid dysfunction was not clear and some of the factors seemed paradoxical. METHODS: We conducted this population-based study using data from 5154 She ethnic minority people who had entered into the epidemic survey of diabetes between July 2007 to September 2009. Life style information was collected using a standard questionnaire. Body mass index (BMI), Blood pressure and serum TSH, TPOAb, triglycerides (TG), total cholesterol (TC) and high-density lipoprotein cholesterol (HDL) were collected. RESULTS: The study showed that people who drank, had higher education or suffered from insomnia have lower incidence of hyperthyroidism. On the other hand, smoking, alcohol consumption, exercise, undergoing weight watch and chronic headache were associated with decreased incidence of hypothyroidism. Using multivariable logistic regression analysis, we found that alcohol consumption was associated with decreased probability of hyperthyroidism, hypothyroidism, as well as positive TPOAb. The amounts of cigarettes smoked daily displayed a positive correlation with hyperthyroidism among smokers. Accordingly, smoking seemed to be associated with decreased risk for hypothyroidism and positive TPOAb. Exercise and maintaining a healthy weight might have a beneficial effect on thyroid health. Interestingly, daily staple amount showed an inverse correlation with incidence of positive TPOAb. CONCLUSIONS: Within the Chinese She ethnic minority, we found associations between different lifestyle factors and the incidence of different thyroid diseases. Understanding the nature of these associations requires further investigations.

RESUMO

BACKGROUND: Our study aimed to evaluate the association between waist circumference (WC) and calcaneal bone mineral density (BMD) in adult Chinese men with normal weight. METHODS: This was a cross-sectional study. A total of 4,663 male participants aged 40 years or older residing in Ningde and Wuyishan, two cities locating in Fujian province of China, were randomly recruited between 2011 and 2012. Each participant should complete a standard questionnaire, undergo anthropometric and calcaneus quantitative ultrasound (QUS) measurements and have blood sample taken. Anthropometric, biochemical and calcaneal QUS parameters of 1,583 male participants with BMI ranging from 18.5 to 22.9 were included in the analysis. WC was divided into quartiles (Q1-Q4: <71, 71-75, 75-78, >78 cm). The relationship between WC (quartiles) and BMD was analyzed by multiple linear regression models. RESULTS: Mean age of the whole population was 54.6±9.8 years. Anthropometric and biochemical parameters were almost normal. Multiple linear regression analysis showed that BMD was negatively associated with increasing WC quartiles except for Q2 after adjusting for age and BMI, and this relationship remained negative except for Q2 when further adjustment was made for other covariates. Multiple logistic regression model also showed that the risks of osteopenia and osteoporosis increased across WC quartiles. CONCLUSIONS: The present study indicated that WC was a negative predictor of calcaneal BMD in adult Chinese men with normal weight. It suggests that, even for the normal-weight Asian males, monitoring accrual of abdominal adipose is still helpful for the purpose of preventing bone loss.

RESUMO

OBJECTIVE: To examine receptors for advanced glycation end-products Gly82Ser polymorphism in patients of type 2 diabetes with comorbid depression. METHODS: The case-control study was conducted at Fujian Provincial Hospital, Fuzhou, China, between December 2011 and December 2012, and comprised unrelated Chinese Han patients of type 2 diabetes, and diabetics with diagnosed clinical depression. Gly82Ser polymorphism polymorphism was determined using polymerase chain reaction amplification-high resolution melting curve protocol. Serum levels of endogenous secretory receptor for advanced glycation end products were measured using enzyme-linked immunosorbent assay. SPSS 16 was used for data analysis. RESULTS: Of the 114 subjects, 72(63.15%) were clinically depressed. Lower levels of endogenous secretory receptor were found in the depression group compared with the other group (p=0.049). No difference in genotypes or allele frequencies existed between the two groups (p>0.05). Gly82Ser carriers had significantly higher Hamilton Rating Scale scores (p<0.001) and lower serum endogenous secretory receptor (p=0.012) among the depressed diabetics. There were also significant differences in body mass index (p=0.005), abdominal circumference (p=0.038), carotid intima-media thickness (p=0.037) and high-sensitivity C-reactive protein (p=0.005) concentration between the different genotypes.. CONCLUSIONS: Receptors for advanced glycation end-products-ligands system may be involved in type 2 diabetes with comorbid depression at the genetic level.

RESUMO

Objective: To assess the association between famine exposure in early life and osteoporosis in adulthood. Methods: A total of 2,292 participants born between 1955 and 1965 in Fujian Province were selected; after 3 years, 1,378 participants attended a follow-up research visit. Calcaneus bone mineral density and bone quality were measured by quantitative ultrasound. The T-score was used to assess bone mineral density, and the parameters quantitative ultrasound index (QUI), speed of sound (SOS), and broadband ultrasonic attenuation (BUA) were used to assess bone quality. A T-score threshold of -1.8 was defined as osteoporosis, and a possible vertebral fracture was considered as a prospective height loss of 0.8 inches or more. Results: Compared with the nonexposed cohort, risks of osteoporosis for fetal-, early childhood, and mid-childhood famine-exposed cohorts in postmenopausal women were adjusted odds ratio (OR), 3.741 (95% confidence interval [CI], 1.233, 11.44) versus OR 2.894 (95% CI, 0.997, 8.571) versus OR 4.699 (95% CI, 1.622, 13.612) by logistic regression but not significant in men. Moreover, the fetal-exposed cohort had a weak negative relation with QUI (ß, -5.07 [-10.226, 0.127]) and BUA (ß, -4.321 [-0.88, 0.238]). The early- and mid-childhood-exposed cohorts had significantly lower QUI (ß, -7.085 [-11.799, -2.372] versus ß, -10.845 [-15.68, -6.01]) and BUA (ß, -6.381 [-10.515, -2.246] versus ß, -8.573 [-12.815, -4.331]) than the nonexposed cohort by linear regression. None of the famine-exposed cohorts had a significant relationship with SOS. Conclusion: Famine exposure during early life is associated with higher risk of osteoporosis in adulthood, which is most obvious in postmenopausal women. Furthermore, famine exposure in early life has adverse effects on bone quality. Abbreviations: BMD = bone mineral density; BUA = broadband ultrasonic attenuation; CI = confidence interval; OR = odds ratio; QUI = quantitative ultrasound index; QUS = quantitative ultrasound; SOS = speed of sound.

RESUMO

OBJECTIVE: To assess the effect of early life exposure to famine, as endured during 1959 to 1961 in China, on reproductive aging in adult women. METHODS: Between 2011 and 2012, 2,868 women born around the Chinese famine period (1956-1964) were enrolled in this study from three communities in China. Age at natural menopause was obtained retrospectively from a structured questionnaire. The associations of early life famine exposure with reproductive aging during adulthood were estimated, with adjustment of socioeconomic status, lifestyle factors, and body mass index. RESULTS: Women exposed to prenatal famine had a higher risk of early menopause (ie, natural menopause <45 years, odds ratio: 1.59, 95% confidence interval [CI]: 1.07, 2.36), and a nonsignificant trend of higher risk of premature ovarian failure (ie, natural menopause <40 y, odds ratio: 1.94, 95% CI: 0.93, 4.00), compared to unexposed women. Exposure to famine during childhood was not significantly associated with reproductive aging. In a secondary analysis focusing on the fetal exposure, prenatal famine exposure was associated with a higher risk of premature ovarian failure (odds ratio: 2.07, 95% CI: 1.08, 3.87), and a nonsignificant trend of higher risk of early menopause (odds ratio: 1.37, 95% CI: 0.98, 1.91), compared to those unexposed to prenatal famine. CONCLUSIONS: Our study showed that fetal exposure to famine was associated with an increased risk of early menopause. Such findings provided evidence in favor of the thrifty phenotype theory in reproductive aging and helped better understand the etiology of early menopause.

RESUMO

BACKGROUND: ß-Cells at different stages have different functions and capacity for proliferation, regenerative and apoptosis. The aim of the present study was to investigate whether there are changes in ß-cell phonotype in the development of diabetes to identify potential ß-cell targets to prevent the progression of diabetes. METHODS: A cross-sectional study was performed on pancreatic tissues obtained from 80 patients classified into three groups: 25 with type 2 diabetes (T2D), 25 with impaired fasting glucose (IFG), and 30 non-diabetics (ND). The ratio of the insulin-positive area to pancreatic area was used as an indirect marker of ß-cell mass. Insulin-positive duct cells and scattered ß-cells were defined as newly generated ß-cells, whereas insulin/neurogenin 3 (Ngn3), insulin/v-maf musculoaponeurotic fibrosarcoma oncogene family, protein A (MafA) and insulin/P16 double-positive cells were defined as immature, mature, and senescent ß-cells, respectively; Ki67 was used as a marker of cell proliferation, and terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labeling (TUNEL) was used as a marker of cell apoptosis. Data were analyzed using the Kruskal-Wallis test. RESULTS: There were no significant differences in ß-cell mass, the prevalence of insulin-positive duct cells, scattered ß-cells, or insulin/Ngn3, insulin/MafA, and Insulin/Ki67 double-positive cells among groups. The incidence of insulin/P16 double-positive cells was significantly higher in T2D than ND. ß-Cell apoptosis was significantly higher in T2D and IFG than ND. CONCLUSION: The senescence and apoptosis of ß-cells may be involved in the course of diabetes.

RESUMO

CONTEXT: Primary hyperparathyroidism (PHPT) is reported to be associated with an increased frequency of hypertension, however, information in this regard is sparse in relation to normocalcemic primary hyperparathyroidism (NPHPT). OBJECTIVE: The aim of this study was to determine the association between NPHPT and blood pressure. DESIGN, SETTING, AND PATIENTS: We retrospectively enrolled 940 patients who visited the Fujian Provincial Hospital between September 2010 and December 2013 with a measured serum parathyroid hormone (PTH) and calcium level. Among them, 11 patients were diagnosed with NPHPT, while 296 cases with normal PTH and albumin-adjusted serum calcium. MAIN OUTCOMES MEASURES: Systolic blood pressure (SBP), diastolic blood pressure (DBP), intact serum PTH, and serum calcium were recorded. RESULTS: There were no significant differences between subjects identified with NPHPT and those with normal PTH in terms of age, sex, body mass index, serum calcium, 25-Hydroxyvitamin D, serum creatinine, fasting plasma glucose, triglycerides, total cholesterol, high density lipoprotein, and low density lipoprotein. The subjects with a diagnosis of NPHPT had higher levels of SBP (141.9 ± 20.2 vs 131.2 ± 16.5, P = .041) and DBP (85.2 ± 12.4 vs 76.8 ± 10.3, P = .026) than the subjects in the cohort with normal PTH. After adjustment for all potential confounders, risks (odds ratios and 95% confidence interval) of SBP and DBP in NPHPT patients were 1.035 (1.000, 1.071) and 1.063 (1.004, 1.125), respectively (P < .05). CONCLUSIONS: The NPHPT had higher risk of high blood pressure than subjects with normal PTH. It is worth considering the necessity of more aggressive therapeutic intervention aimed to normalize PTH even if patients with NPHPT continue to be normocalcemic.

RESUMO

OBJECTIVE: Determine the serum levels of endogenous secretory receptor for advanced glycation end products (esRAGEs) in patients with type 2 diabetes and mild cognitive impairment (MCI) and in control patients with type 2 diabetes but no MCI, and examine the relationship of esRAGE and MCI with other clinical factors. RESEARCH DESIGN AND METHODS: A total of 101 patients with type 2 diabetes who were hospitalized in the Department of Endocrinology at Fujian Provincial Hospital between January 2010 and January 2011 were enrolled. There were 58 patients with MCI and 43 patients without MCI (control). Serum levels of esRAGE were measured using an enzyme-linked immunosorbent assay (ELISA). Other clinical parameters were also measured. RESULTS: Type 2 diabetic patients with MCI had a longer duration of diabetes; elevated HbA(1c), total cholesterol (CHOL), LDL cholesterol (LDL-C), triglyceride (TG), intima-media thickness, C-reactive protein (CRP), and brachial-ankle pulse wave velocity (ba-PWV); and lower ankle brachial index (ABI) and esRAGE relative to the control group. Among patients with MCI, the Montreal Cognitive Assessment (MoCA) score was positively correlated with serum esRAGE but negatively correlated with CHOL. Spearman rank correlation analysis indicated that esRAGE was positively correlated with MoCA score and ABI but negatively correlated with ba-PWV, CHOL, TG, and CRP in all subjects. CONCLUSIONS: Our results suggest that esRAGE may be a potential protective factor for dyslipidemia, atherosclerosis, and MCI in patients with type 2 diabetes.
