FRs can be considered a double-edged sword. Beneficial effects of FRs occur at moderate concentrations and involve physiological roles in cellular responses to noxia, as in defense against infectious agents, in the function of a number of cellular signaling pathways and the induction of a mitogenic response. The over-production of FRs and the insufficiency of an antioxidant mechanism result in oxidative stress (OS), a deleterious process and important mediator of damage to cell structures and tissues. It occurs at birth in all newborns as a consequence of the hyperoxic challenge after the transition from the hypoxic intrauterine environment to extrauterine life. During the perinatal period, OS can be magnified by others predisposing conditions such as hyperoxia, hypoxia, ischemia, hypoxia-reperfusion, inflammation and high levels of non-protein bound iron. Epidemiological studies linked OS occurring during fetal stages and early infancy with adverse health outcomes later in life, indicating that OS is an early event in the etiology of these chronic diseases. Newborns, especially if preterm, are particularly susceptible to OS and damage due to the increased generation of FRs, the lack of adequate antioxidant protection, and the inability to induce antioxidant defenses during the hyperoxic challenge at birth. This impairment of the oxidative balance has been thought to be the common factor of pathologies grouped together as “free radical disease in the neonate” that include retinopathy of prematurity (which may lead to blindness in severe cases), bronchopulmonary dysplasia (a particularly debilitating pulmonary lesion of the preterm infant), periventricular leukomalacia (an important cause of severe neurodisability) and necrotizing enterocolitis. In this review we discuss in detail these perinatal diseases. Particularly, we analyze the current knowledge about the role of OS in their pathogenesis.展开更多

Methods A total of 309 infants born on 1st August, 2003 to 30th August, 2004 and their families were recruited as participants by cluster sampling in Longhua and Kantian sub-districts of Xuhui district, Shanghai. The newborns were randomly assigned to intervention group (156 cases) and control group (153 cases). The infants and their families will be followed up during 3-year interventions. Results After 6 months' intervention, the proportion of infants who could turn over the body in the intervention group (88.46%) was higher than that in control group (75.16%). The morbidity of upper-respiratory tract infection in intervention group (20.51%) was significantly lower than that in control group (32.68%). The incidence rates of pneumonia, diarrhea and anemia in intervention group were all lower than that in control group, except for pneumonia, the differences were not significant. Both of the knowledge about how to foster infants and service utility in intervention group were higher than that in control group. Conclusion The fostering interventions through the community promote the prevention and control of infants disease, increase the knowledge level and service util ity of families.展开更多

Infants with PNALD were younger by gestation (27 vs. 29.5 weeks) and smaller by birthweight (900 vs. 1248 grams). Sepsis, GI disease including necrotizing enterocolitis and bowel resection were significantly associated with an increased risk for development of PNALD. PNALD infants received lower protein doses (3.0 vs 3.3 g/kg/day, p = 0.014) while receiving higher GIR (11.4 vs 10.7 mg/kg/min, p = 0.012) compared to non-PNALD infants. Low birth weight, sepsis and bowel resection remain strong indicators of risk for PNALD. No single macronutrient increased our infants’ risk for PNALD. The use of newer ILEs when available should be evaluated for their impact on PNALD development.展开更多

Methods: Outcomes of two different surgical repairs for coarctation of the aorta in 43 infants were evaluated retrospectively. The study was designed as a nonrandomized, cross-sectional study. The subclavian flap repair was applied to 22 patients (51%) and resection with extended end-to-end anastomosis technique to 21 patients (49%). After all operative survivors were followed up with a mean follow-up of 1.8 ± 0.8 years, data analyzed with t-test and the p value < 0.05 were considered statistically significant. Results: The overall mortality rate was 4.6%. Forty mmHg gradients were determined in a patient from Resection Group postoperatively in the fifteenth month. After the balloon angioplasty, the gradient decreased to 25 mmHg. The presence of ventricular septal defect (p = 0.094) was the only significant predictor of adverse short-term outcome among the associated cardiac defects analyzed. The first-year survival rate was 100% in both groups in isolated coarctation (p = 0.965), however;such rate was found as 100% and 93.25% in Waldhausen Group and Resection Group, respectively in complex coarctation (p = 0.294). Conclusions: Both the subclavian flap repair and resection with extended end-to-end anastomosis for coarctation of the aorta in infants provide excellent short-term outcomes with lower recurrence rates requiring surgery or angioplasty.展开更多

文摘AIM:To investigate evidence of clinical protection in infants after one dose of 7-valent pneumococcal conjugate vaccine(7vPCV) owing to carrier priming.METHODS:Using Australian National Notifiable Diseases Surveillance System data,we conducted a descriptive analysis of cases of vaccine type invasive pneumococcal disease(VT-IPD) during "catch-up" years,when 7vPCV was carrier primed by prior administration of DTPa vaccine.We compared the number of VT-IPD cases occurring 2-9 wk after a single dose of 7vPCV(carrier primed),with those < 2 wk post vaccination,when no protection from 7vPCV was expected yet.Further comparison was conducted to compare the occurrence of VT-IPD cases vs non-VT-IPD cases after a single carrier-primed dose of 7vPCV.RESULTS:We found four VT-IPD cases occurring <2 wk after one carrier primed dose of 7vPCV while only one case occurred 2-9 wk later.Upon further comparison with the non-VT-IPD cases that occurred after one carrier primed dose of 7vPCV,two cases were detected within 2 wk,whereas seven occurred within2-9 wk later;suggesting a substantial level of protection from VT-IPD occurring from 2 wk after carrier-primed dose of 7vPCV.CONCLUSION:This data suggest that infants may benefit from just one dose of 7vPCV,likely through enhanced immunity from carrier priming effect.If this is proven,an adjusted 2-dose schedule(where the first dose of PCV is not given until after DTPa) may be sufficient and more cost-effective.

文摘Background:To achieve successful management of infants with congenital heart disease(CHD)together with pulmonary hypertension(PH),postoperative care,especially feeding care is vital in addition to surgery.Postoperative feeding is comprised of three stages:feeding in the intensive care unit,feeding in the general ward and family feeding,in which the general ward is considered as the“transitional stage”.At present,there is little research on the optimal mode of feeding care for the transitional stage,and there is no universally recognized and accepted protocol.Methods:We retrospectively analyzed 114 CHD infants with PH who underwent family-centered(FC)feeding care from July 2017 to December 2018,and prospectively studied 122 CHD infants with the same baseline level who adopted the improved mode,nurse-parent-driven(NPD)feeding mode from January 2019 to June 2020.The feasibility and efficacy of NPD as a“transitional”feeding nursing mode in CHD infants with PH were compared with the FC cohort by observing and analyzing the stress of family caregivers,feedingrelated complications,the proportion of breastfeeding,improvement of nutritional status,acquisition of knowledge and skills of feeding care,inpatient’s satisfaction rating and prognosis.Results:When compared with the FC feeding care,the NPD mode significantly reduced the burden of family caregivers,improved the rate of feeding care knowledge and skills and inpatient’s satisfaction rating,reduced the incidence of improper feeding-related complications,and enhanced the proportion of breastfeeding and nutritional status of infants at the“transitional stage”(all P<0.05).The self-assessment score of care ability of family caregivers and weight gain of children in the NPD group were significantly higher than those in the FC group(all P<0.05)during the follow-up.Conclusions:As a transitional mode of feeding in CHD infants with PH,NPD feeding care is superior to the conventional FC mode,which therefore can be adopted as a standard protocol in clinical practice.
文摘Background: The aims of the study were to analyze the importance of two different surgical procedures, and to determine outcomes for neonates with coarctation of the aorta in two newly established centers. Methods: Outcomes of two different surgical repairs for coarctation of the aorta in 43 infants were evaluated retrospectively. The study was designed as a nonrandomized, cross-sectional study. The subclavian flap repair was applied to 22 patients (51%) and resection with extended end-to-end anastomosis technique to 21 patients (49%). After all operative survivors were followed up with a mean follow-up of 1.8 ± 0.8 years, data analyzed with t-test and the p value < 0.05 were considered statistically significant. Results: The overall mortality rate was 4.6%. Forty mmHg gradients were determined in a patient from Resection Group postoperatively in the fifteenth month. After the balloon angioplasty, the gradient decreased to 25 mmHg. The presence of ventricular septal defect (p = 0.094) was the only significant predictor of adverse short-term outcome among the associated cardiac defects analyzed. The first-year survival rate was 100% in both groups in isolated coarctation (p = 0.965), however;such rate was found as 100% and 93.25% in Waldhausen Group and Resection Group, respectively in complex coarctation (p = 0.294). Conclusions: Both the subclavian flap repair and resection with extended end-to-end anastomosis for coarctation of the aorta in infants provide excellent short-term outcomes with lower recurrence rates requiring surgery or angioplasty.
文摘BACKGROUND Anti-D antibody is not the common cause of Rh-isoimmunization in Chinese neonatal jaundice.Recent change in national population policy has followed by an increase in Rh-isoimmunization related hemolytic disease of the newborn(HDN).Unfortunately,regional status of Rh-HDN is unavailable.We hypothesize that Rh-HDN in our region is most commonly due to anti-E antibody.AIM To investigate the prevalence of hemolytic disease of the newborn due to Rhisoimmunization in Hefei City.METHODS Retrospective review of data obtained from Children’s Hospital of Anhui and Hefei Blood Center between January 2017 and June 2019.Status of minor blood group antibody was studied in the corresponding mothers.RESULTS Totally 4138 newborns with HDN admitted during the study period and 116(2.8%)received blood exchange transfusion(BET).Eighteen newborns(0.43%)with proven Rh-incompatible HDN were identified.All were not the first-born baby.Thirteen mothers were RhD(+)(72%)and five were RhD(-).The distribution of Rh-related antibodies in mothers was ten anti-E(55%),five anti-D(27%),and for one anti-C,anti-c,and anti-E/c(6%)each.Thirteen(72.2%)were qualified for BET,relative risk for BET was 28.9 as compared to other types of HDN,but only 10 received due to parenteral refusal.All(100%)RhD related HDN received BET which is not significantly different from RhE related HDN(81.8%).CONCLUSION As expected,all Rh-incompatible HDN newborns were not the first-born.Contrary to the Caucasian population,anti-D induced HDN is not the most common etiology.In our region,anti-E(11/18,61%)is the most common cause of Rh-HDN.
