ABSTRACT
Objective To explore the effect of gestational hypertension on multiple organ system in neonates. Methods A total of 100 newborns whose mother had pregnancy complicating primary hypertension admitted to our hospital from December 2011 to December 2012 were selected and divided into preeclampsia group (n=53), gestational hypertension group (n=47) according to the blood pressure during pregnancy. Meanwhile, 100 newborns with healthy mother were selected as control group including 12 term infants and 88 premature infants. Data including birth weight, length and head circumference, Apgar score, the percentage of amniotic lfuid pollution, placental abruption and fetal distress, Neonatal Behavioral Neurological Assessment (NABA) score, serum level of creatine kinase, pulmonary arterial pressure, thyroid function, blood glucose, blood routine, cranial MRI parameters were collected and compared among three groups. Results In preeclampsia group, the gestational age, birth weight and head circumference, 1-min and 5-min Apgar scores were lowest while the ratio of low birth weight infants was highest among three groups, and the differences were signiifcant (P<0.05). In preeclampsia group, the rates of antenatal abnormalities (amniotic lfuid meconium III degree pollution, placental abruption and fetal distress) and complications (severe infection, myocardial damage, neonatal polycythemia, liver and kidney damage, hypoglycemia, hypothyroidism and respiratory failure) were highest among three groups, and the differences were signiifcant (P<0.01). In preeclampsia group, the red blood cell count, the levels of hemoglobin, hematocrit and thyroid stimulating hormone were signiifcantly higher than those in the other two groups ( P<0.05 ), and the white blood cell and platelet count was signiifcantly lower than that in the control group (P<0.05). The passive muscle tension scores in preeclampsia group were signiifcantly lower than those in the other two groups (P<0.05).The abnormity rate of cranial MRI in preeclampsia group was highest among three groups, and the difference was signiifcant (P<0.01). Conclusions Gestational hypertension may cause multisystem disorders in newborns, such as fetal intrauterine growth restriction, endocrine system disorders, heart dysfunction, increased blood viscosity, delayed neurodevelopment. The severity of gestational hypertension is associated with the adverse impact on the multiple systems in neonates.
ABSTRACT
Objective To explore the roles of serum TLR-4, TNF-αand IL-6 in neonates with preterm birth. Methods A total of 120 neonates from neonatology department in the Xingtai People's Hospital were selected and divided into full-term group (n=40), premature rupture of fetal membranes (n=40) and idiopathic preterm group (n=40) based on the gestational age. The peripheral venous blood was collected within 30 minutes when the infants were born, and the supernatant was reserved after centrifuged. The levels of serum TLR-4, TNF-αand IL-6 were detected by enzyme-linked immunosorbent assay. Results The levels of TLR-4, TNF-αand IL-6 in idiopathic preterm and premature rupture of fetal membranes were signiifcantly higher than that in full-term group and showed positive correlation. Conclusion Cytokines TLR-4, TNF-αand IL-6 maybe closely related to the preterm birth.
ABSTRACT
Objective To elucidate the malnutrition in patients with hospital-acquired acute kidney injury(AKI), and to examine the association betweensubjective global assessment (SGA) and prognosis.Methods Adult patients with hospital-acquired AKI were prospectively enrolled in this cohort study.Nutritional evaluations, including SGA, anthropometric and serum nutritional markers were conducted at enrollment.Overall survival at 90 days among different SGA scores was analyzed using Kaplan-Meier methods, and differences were tested using the log-rank test.The Cox model was used to analyze the relationship between SGA scores and all-cause mortality after adjusting for confounders.Results A total of 170 patients were enrolled.The prevalence of moderate malnutrition(SGA B) and severe malnutrition(SGA C) was 51.8％ and 22.9％ respectively, while patients with normal nutrition(SGA A) accounted for 25.3％.After 90 days follow-up, all-cause mortality was 9.8％ in SGA A group, 34.9％ in SGA B group and 56.8％inSGACgrouprespectively. Afteradjustingforage,sex,dialysis,ventilation, hemoglobin, platelets and bilirubin, the hazard ratio(HR) of 90 days all-cause mortality was 4.0(95％ CI 1.42-11.22, P=0.008) in malnutrition group (SGA B group and SGA C group) compared with SGA A group.The Kaplan-Meier curve also revealed that the worse the SGA score was, the lower the cumulative survival became (P＜0.01).Conclusion SGA score is an independent risk factor for all-cause mortality within 90 days in patients with hospital-acquired acute kidney injury.
