  • Annual result of retinopathy of prematurity screening in Shanghai area

    Objective To investigate the incidence of retinopathy of prematuri ty (ROP) in the area of Shanghai, and to provide the preliminary data for the ev aluation of present criteria for ROP screening. Methods Record s of 289 prematur e infants who had undergone ROP screening from the four NICU in Shanghai between February 2004 and January 2005 were analyzed. Screening criteria included prete rm infants or low birth weight (LBW) infants with BW of 2000g or less. The first examination starts at 4 to 6 weeks chronologic age or 32 weeks post conceptual age. Results In the 289 screened infants, 19 had developed acu te ROP. There we re 3 threshold ROP, 7 prethreshold ROP and 9 developed ROP less than prethreshol d. The incidence of ROP was 6.6%. According to the British recommended guideline s(BWle;1500 g or GAle;31 weeks), only 119 out of 289 needed screening and one ca se of stage 1 ROP was missed; the incidence of ROP was 15.1% (18/119). When lowered sc reening criteria to the American guidelines(BWle;1500g or GAle;28 weeks), t here were only 83 infants needed screening, and we missed 2 stage 1 and 1 prethreshold ROP and the incidence of ROP was 19.3% (16/83). Conclusions The i ncidence of ROP i s 6.6% according to our study. It is lower than other reports and it has somethi ng to do with our present screening guideline. Further epidemiological data are needed to modify the guideline accordingly.

  • The economic evaluation of screening and early diagnosis of primary immunodeficiency diseases: a systematic review

    ObjectiveTo systematically review the economics evaluation studies on the early screening or diagnosis of primary immunodeficiency diseases (PID). MethodsWeb of Science, CRD, PubMed, The Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect the economics evaluation studies on the early screening or diagnosis of PID from inception to July 1st, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, a descriptive systematic review was performed. ResultsA total of 10 studies focusing on SCID were included. The results showed that under a relatively high threshold, the early screening and diagnosis of SCID were cost-effective, which can reduce severe infections in patients and treatment costs while improving patient’s survival. ConclusionCurrent evidence shows that early diagnosis of PID can reduce costs and improve benefits. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.

  • Retinal hemorrhage in newborns and associated factors

    Objective To observe the fundus characteristics and associated factors of retinal hemorrhage (RH) in newborns. Methods A total of 293 healthy newborns (586 eyes) were enrolled in this study. A digital wide-angle retinal imaging device (RetCam Ⅲ) was used to examine the subjects at about 2 days after birth (2.7plusmn;0.9) days. The images of posterior pole, temporal quadrant, superior quadrant, nasal quadrant and inferior quadrant of the fundus of each eye were taken sequentially. Every newborn completed the examination and the mean duration of the procedure was (2.62plusmn;0.55) minutes. Newborns with RH were reexamined after one month. RH was classified according to the location and size of the hemorrhages based on guidelines in the literature. The location and degree of RH was determined in each newborn. The incidence of RH by gender, parity, birth weight, maternal age and delivery method was compared and analyzed. Results RH was present in 87 eyes (14.8%) of 58 newborns (19.8%) and of the 58 newborns with RH, half (29 eyes) had hemorrhages in both eyes, and half (29 eyes) had hemorrhages in only one eye. The site of the hemorrhage was all on the superficial retina. Of the 87 eyes with RH, 72 eyes (82.8%) had hemorrhage in zone Ⅰ, 86 eyes (98.9%) had hemorrhage in zone Ⅱ, and 36 eyes (41.4%) had hemorrhage in zone Ⅲ. Thirty-eight eyes (43.7%) had hemorrhage in zone Ⅰand Ⅱ. Three eyes (3.4%) had hemorrhage in zone Ⅱ and Ⅲ. Thirtythree eyes (37.9%) had hemorrhage in zone Ⅰ, Ⅱ and Ⅲ. One eye (0.4%) had hemorrhage in zoneⅠonly. Twelve eyes (13.8%) had hemorrhage in zone Ⅱ only. None had hemorrhage in zone Ⅲ only. The severity of RH was grade Ⅰ in 13 of 87 eyes (14.9%), grade Ⅱ in 33 of 87eyes (37.9%), and grade Ⅲ in 41 of 87 eyes (47.1%). Fourteen of 58 newborns with RH (24.1%) were lost to follow-up. Forty-four of 58 newborns with RH (75.9%) were reexamined one month after birth and all the RH disappeared entirely. There were no statistically significant differences among the incidences of RH of the different gender (chi;2=0.018,P=0.893), parity(chi;2=0.772,P=0.380), birth weight(chi;2=1.611,P=0.447)and maternal age (chi;2=0.915,P=0.339). The incidence of RH was higher for vaginal delivery than that for cesarean section delivery (chi;2=3.073,P<0.05). Conclusions The RH in newborn is located in the superficial retina, mostly located in zone Ⅰor zone Ⅱ, and resolves itself within one month after birth. The RH in newborns is related to the mode of delivery, but not related to gender, parity, birth weight or maternal age.

  • Diagnostic accuracy of TRECs in newborn screening for severe combined immunodeficiency: a meta-analysis

    ObjectiveTo systematically review the accuracy of T-cell receptor excision circles (TRECs) in screening newborns for severe combined immunodeficiency (SCID). MethodsThe PubMed, EMbase, Cochrane Library, Web of Science, CBM, WanFang Data and CNKI databases were electronically searched to collect the diagnostic accuracy studies related to the objects from inception to October 26, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies using the QUADAS-2 scale. Meta-analysis was performed using Stata 15.0 and Meta-Disc 1.4 software. ResultsA total of 18 studies involving 6 243 718 neonates were included. The results of meta-analysis showed that the pooled sensitivity (SEN), specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnosis odds ratio (DOR) were 0.97 (95%CI 0.92 to 0.99), 1.00 (95%CI 1.00 to 1.00), 1447.05 (95%CI 528.49 to 3962.11), 0.13 (95%CI 0.08 to 0.22) and 11698.21 (95%CI 2853.44 to 47958.98), respectively. The area under the summary receiver operating characteristic curve (SROC) was 0.97. ConclusionThe application of TRECs in screening neonatal SCID has high accuracy, which is helpful for early diagnosis of SCID. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
