Objective Effect of physical exercise on pregnant women currently has become a hot topic in prenatal health care. In this study, A meta-analysis was conducted on account of Randomized Controlled Trial (RCT). It focused on evaluating the effect of physical exercise intervention on blood pressure so that could provide certain evidence for health care during pregnancy. Methods Results of relevant studies were retrieved from PubMed, Embase, Web of Science and the Cochrane Library, and all of these included studies were evaluated according to the Cochrane collaboration’s tool for assessing the risk of bias. Stata 15.1 was used for meta-analysis, and mean difference (MD) was used as statistic for pooled analysis. The effect values were combined by conventional meta-analysis and Bayesian meta-analysis respectively, and the consistency of pooled results was considered as well. Results A total of 18 RCT studies were included in the quantitative analysis. The conventional meta-analysis showed differences in blood pressure between intervention group and control group (P < 0.05). Systolic and diastolic blood pressures of intervention group were 3.19 mmHg (95% CI: -5.13, -1.25) and 2.14 mmHg (95% CI: -4.26, -0.03) lower than that of control group, respectively. Bayesian meta-analysis showed that both systolic and diastolic pressure among intervention group decreased by 3.34 mmHg (95% CrI: -5.15, -1.56) and 2.14 mmHg (95% CrI: -3.79, − 0.50), respectively. Subgroup analysis supported that as long as healthy pregnant women participated in exercises, their blood pressure could be slightly regulated, while hypertension susceptible pregnant women significantly lowered blood pressure. Conclusion Exercise intervention during pregnancy is beneficial to lower or normalize blood pressure, and this research provides clues for follow-up studies.
ObjectiveThis cross-sectional study analyzed the clinical characteristics of newly diagnosed Graves' disease (GD) in children and adolescents to provide clinical evidence for the early diagnosis of GD.MethodFrom 2013 to 2019, information on children and adolescents with newly diagnosed GD admitted to the Department of Endocrinology, Children's Hospital of Nanjing Medical University, was collected, including clinical features and laboratory tests. The data were summarized and statistically analyzed.ResultThis study included 204 cases of newly diagnosed GD, with 158 females and 46 males. The average age at initial diagnosis was 8.9 ± 2.9 years. A total of 132 cases (64.7%) had symptoms before puberty, and 72 cases (35.3%) had symptoms during puberty. Goiter was detected in 193 cases (94.6%). There were 140 cases (68.6%) of exophthalmos, and 21.4% (30/140) were infiltrative. At initial diagnosis, 10 cases (4.9%) reported leukopenia, 18 cases (8.8%) reported neutropenia, and 15 cases (7.4%) reported mild anemia. There was 1 (0.5%) case of thrombocytopenia and 1 (0.5%) case of agranulocytosis. Fifty-four cases (26.5%) had impaired liver function.ConclusionGD is more common in female children and adolescents. Parents may ignore their children's hypermetabolic symptoms in the early stages of GD. Routine blood and liver function tests are recommended at initial diagnosis to exclude abnormal hemogram and liver function.
Background: Ambient air pollution is closely related to a variety of health outcomes. Few studies have focused on the correlations between air pollution exposure and children’s sexual development. In this study, we investigated the potential effects of exposure to air pollution on precocious puberty among children using real-world evidence. Methods: We conducted a case-crossover study (n = 2201) to investigate the effect of ambient air pollution exposure on precocious puberty from January 2016 to December 2021. Average exposure levels of PM2.5, PM10, SO2, NO2, CO, and O3 before diagnosis were calculated by using the inverse distance weighting (IDW) method. Distributed lag nonlinear model (DLNM) was used to assess the effect of air pollutants exposure on precocious puberty. Results: The mean age of the children who were diagnosed with precocious puberty was 7.47 ± 1.24 years. The average concentration of PM2.5 and PM10 were 38.81 ± 26.36 μg/m3 and 69.77 ± 41.07 μg/m3, respectively. We found that exposure to high concentrations of PM2.5 and PM10 might increase the risk of precocious puberty using the DLNM model adjusted for the age, SO2, NO2, CO, and O3 levels. The strongest effects of the PM2.5 and PM10 on precocious puberty were observed in lag 27 (OR = 1.72, 95% CI: 1.01–2.92) and lag 16 (OR = 1.95, 95% CI: 1.33–2.85), respectively. Conclusion: Our findings supported that short-term exposure to air pollution was the risk factor for precocious puberty. Every effort should be made to protect children from air pollution.
ObjectiveTo describe the thyroid function test among children with abdominal distention and to follow up the treatment received by children with abnormal thyroid function.DesignCross-sectional study.Setting and participantsA total of 1089 children (median age:30 days (IQR=21–60 days) with abdominal distension were included in this single centre study in Nanjing, China.ResultThyroid dysfunction was found in 43 of 148 Hirschsprung’s disease (HSCR) cases, with 3 (2.03%) having hypothyroidism, 3 (2.03%) having subclinical hypothyroidism and 3 (2.03%) having subclinical hyperthyroidism. Thyroid dysfunction was found in 206 of 941 functional abdominal distension cases, with 4 (0.43%) having hypothyroidism, 23 (2.4%) having subclinical hypothyroidism, 28 (2.9%) having subclinical hyperthyroidism and 1 (0.11%) having hyperthyroidism. Among total 65 cases (9 from HSCR, 56 from functional abdominal distension) diagnosed with thyroid diseases, 12 were treated with levothyroxine (LT-4), of which 9 were discontinued treatment at about 2 years old, and 3 were still receiving LT-4. Thirty-two cases received no treatment and thyroid function returned to normal in about 1 month. Twenty-one cases were lost during the follow-up.ConclusionThe paediatrician should be vigilant for hypothyroidism when dealing with children with abdominal distension. Thyroid function should be followed up rather than simply administering a short-term levothyroxine treatment.
