Our study identified DUOX2 mutations in 14·9% of Chinese patients investigated with CH and goitre. Because the relationships between DUOX2 genotypes and clinical phenotypes are extremely complex, however, further studies are needed to identify more mutations in known genes which are involved in CH and goitre.

The study population consisted of 105 patients with stage IA to IIB cervical adenocarcinoma (AC) who underwent radical hysterectomy and pelvic lymphadenectomy from three institutions between 1994 and 2015, including 86 patients with bilateral salpingo-oophorectomy (BSO) and 19 patients with ovarian preservation operation. Ovarian metastasis were diagnosed in 3 of 86 patients in BSO group with an incidence rate of 3.5% (3/86). Among the 19 patients with ovarian preservation, none developed an ovarian recurrence in the follow-up (2-71 months). The 5-year overall survival rate of the BSO group and ovarian preservation group were 88.6% and 100%, respectively, with no significant difference (p = .266 > .05). FIGO stage was an independent risk factor of ovarian metastasis for cervical AC (p = .000 < .05). So we concluded that ovarian preservation in young women with early-stage cervical AC may be safe and not associated with an increased risk of overall mortality. Impact statement There has been long-running considerable controversy regarding ovarian preservation in women with cervical AC. The incidence of ovarian metastasis in AC varies significantly from 0% to 12.9%. There were few studies regarding the prognosis and risk factors of cervical AC patients with ovarian preservation. No preoperative selection criteria of ovarian preservation in cervical AC have been officially recommended. In our study of 105 patients with stage IA to IIB cervical AC, the overall ovarian metastasis rate was 3.5% (3/86), and the incidence was 1.5% (1/66) with stage IA to IB. The 5-year overall survival rate of 19 cervical adenocarcinoma patients with ovarian preservation was 100%, and no ovarian recurrence was observed during the follow-up. Our univariate analysis with clinicopathologic variables revealed that only FIGO stage was the risk factor associated with ovarian metastasis of cervical AC. Our data implied that ovarian preservation in young women with early-stage cervical AC might be safe and not associated with an increased risk of overall mortality. Considering the deleterious effects of surgical castration on the long-term quality and quantity of life, we hold that ovarian preservation should be seriously considered in the surgical management of premenopausal women with early-stage cervical AC.

Background: This study aimed to explore the predictive value of a clinical biochemistry-based nomogram in COVID-19.Methods: The plasma or serum concentrations/levels of carcinoembryonic antigen (CEA) and other biomarkers, e.g., C-reactive protein (CRP), white blood cell (WBC), interleukin-6 (IL-6), ferritin (Fer), procalcitonin (PCT), lymphocyte percentage (L%), D-dimer (D2), and neutrophils percentage (Neu%), were assessed in 314 hospitalized patients with confirmed COVID-19. The area under the curve was used to estimate the diagnostic and prognostic value for COVID-19. Cox and logistic regression analyses were used to estimate the independent prognostic risk factors for the survival of patients with COVID-19.Results: Receiver operating characteristic (ROC) curves were used to determine the area under the curve (AUC) values for CEA, IL-6, CRP, PCT, Fer, D-dimer levels and L%, Neu%, and WBC to assess disease classification. The critical values for these markers to predict severe disease type were then determined. The hazard ratio of prognosis for risk of COVID-19 identified CEA, WBC, CRP, PCT, Fer, D-dimer, Neu%, and L% as independent prognostic factors. For the nomogram of overall survival (OS), the C-index was 0.84, demonstrating a good discriminative performance.Conclusions: An OS nomogram for the clinical diagnosis and treatment of COVID-19 was constructed using biomarkers. These data will be useful for the diagnosis, management, and therapy of COVID-19.

Background To investigate the prevalence and risk factors of premature thelarche (PT) in girls and gynecomastia (GM) in boys in Southern China. Methods We conducted a cross-sectional study of preschool children across 9 cities in Zhejiang province. A total of 6273 children in the age-group of 2–7 years were recruited from January 2014 to March 2015. Relevant information was collected from mothers through face-to-face interviews. Logistic regression models were used to examine the correlates of PT and GM. Odds ratios (ORs) with 95% confidence intervals (CIs) are reported. Results The prevalence of PT among girls was 4.8% and that of GM among boys was 0.8%. One hundred girls were diagnosed with PT before the age of 2 years; 69 (69.0%) of these girls experienced spontaneous resolution of PT. Twenty-four boys were diagnosed with GM before the age of 2 years; 10 (41.7%) of these experienced spontaneous resolution of GM. Children borne of mothers with early onset of menarche and those belonging to high-income families were at a higher risk of premature breast development. Greater consumption of eggs was associated with premature breast development in early childhood. Conclusions Socioeconomic status of family, early onset of menarche in mother, and consumption of eggs were strongly associated with premature breast development in early childhood.
