Lethal severe congenital tracheal stenosis with tracheal ring complicating respiratory distress syndrome in an extremely premature infant: first reported case in Qatar with a literature review

Successful pregnancies in post-kidney transplant couples: four case reports

Background

The fertility of female kidney transplant recipients is increasing with the progression of transplant management. This article aims to evaluate the clinical prognosis of mothers and newborns for post-kidney transplant couples.

Methods

From January 2019 to April 2022, a total of four couples, all kidney transplant recipients, were successfully prepared for pregnancy after a rigorous preconception evaluation, including three cases of natural conception and one case of in vitro fertilization. Data regarding the mother and newborn, including general clinical condition and laboratory results, were recorded and assessed throughout the pregnancy and up until 12 months after delivery.

Results

The mean conception age of the mothers was 34.8 years (30-38 years), and the mean interval between renal transplantation and pregnancy was 6.6 years (3.7-8.7 years). All deliveries were by cesarean section and took place without incident. There were three premature births (<37 weeks; average 35.1 weeks). In case 1 (in vitro fertilization), pre-eclampsia occurred during maternity, and this was the only case in which the fetal weight was less than 2,500 g (average 2,576.7 g). The mean Apgar score (1 min) was 7.8 (6-9) and reached 9 in all cases at 5 min. The mothers' eGFR rose during mid-gestation, decreased in late pregnancy, and was largely restored along with proteinuria 1 year postpartum. Postnatal evaluation at 6 months showed normal neurological development. In addition, NK cell and IFN-γ levels increased and Treg cell and IL-10 levels decreased along with the onset of pre-eclampsia.

Conclusions

Pregnancies can succeed in couples who are both kidney transplant recipients. However, there might be higher risks of infertility, prematurity, and low birth weight.

Effect of Continuous Nutrition Management Intervention on Nutritional Status and Development of Premature Infants Based on Mobile Medical APP

Objective

To explore the effect of continuous nutrition management intervention based on mobile medical APP on the nutritional status and development of premature infants.

Methods

Eighty premature infants treated in our hospital from May 2019 to April 2021 were enrolled. The patients were randomly divided into the control group and research group. The control group received routine nursing, and the research group received continuous nutrition management intervention based on mobile medical APP. The Neonatal Behavioral Neurological Assessment (NBNA) score, pain score, height, weight, head circumference, intellectual development score, serum Prealbumin (PA), retinol-binding protein (RBP), and disease occurrence were elucidated.

Results

First of all, the NBNA scores of the two groups were compared. The behavioral ability, passive muscle tension, active muscle tension, original reflex, and general evaluation scores of the research group were significantly higher when compared to the control. Secondly, we compared the pain scores of the two groups, there was no significant difference between the two groups before nursing (P > 0.05), but the pain scores of the research group were lower compared to the control group during the period of blood collection, recovery, discharge, and 6 months after discharge (P < 0.05). Compared with the growth and development indexes of the two groups, there was no significant difference between the two groups before nursing (P > 0.05). After nursing, the GDS score of the two groups increased, and the GDS score of the research group was higher than that of the control group. The difference of data was statistically significant (P < 0.05). Compared with the motor scores of the two groups, there was no significant difference between the two groups before nursing (P > 0.05). After nursing, the motor scores of the two groups increased, and the scores of PDMS-2 and TIMP in the research group were higher than those in the control group, and the difference was statistically significant (P < 0.05). There was no significant difference in serum PA and RBP before nursing, but the serum PA and RBP in the two groups increased after nursing, and the PA and RBP in the research group were higher than those in the control group, and the difference was statistically significant (P < 0.05). Finally, we compared the incidence of diseases between the two groups. Before nursing, the incidence of infection, retinopathy, chronic lung injury and anemia in the research group was lower, when compared to the control, and the difference was statistically significant (P < 0.05).

Conclusion

The intervention strategy of continuous nutrition management based on mobile medical APP for premature infants can significantly strengthen their nutritional status after discharge, promote their growth and development, improve their nutritional status, reduce the incidence of diseases in premature infants, and then enhance their quality of life.

Tracheal Reconstruction for Congenital Tracheal Stenosis: A 950-gram Neonate

Congenital tracheal stenosis (CTS) is a rare but life-threatening malformation of the trachea. Surgical reconstruction is high-risk, and not frequently performed in neonates born of extreme prematurity and low birthweight. We present the case of an extremely premature 950-gram neonate with severe CTS who underwent tracheal reconstruction. Complete repair, with no residual stenosis, was achieved with slide tracheoplasty without the need for cardiopulmonary bypass.
