A multicentre study on the clinical characteristics of newborns infected with coronavirus disease 2019 during the omicron wave.

Objective: To investigate the clinical characteristics and outcomes of newborns infected with coronavirus disease 2019 (COVID-19) during the Omicron wave.

Methods: From December 1, 2022, to January 4, 2023, clinical data were collected from neonates with COVID-19 who were admitted to 10 hospitals in Foshan City, China. Their epidemiological histories, clinical manifestations and outcomes were analysed.

Short term outcomes of extremely low birth weight infants from a multicenter cohort study in Guangdong of China.

With the increase in extremely low birth weight (ELBW) infants, their outcome attracted worldwide attention. However, in China, the related studies are rare. The hospitalized records of ELBW infants discharged from twenty-six neonatal intensive care units in Guangdong Province of China during 2008-2017 were analyzed.

Clinical treatment outcomes and their changes in extremely preterm twins: a multicenter retrospective study in Guangdong Province, China.

Objectives: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.

Methods: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017.

Short-term outcomes of extremely preterm infants at discharge: a multicenter study from Guangdong province during 2008-2017.

Background: An increasing number of extremely preterm (EP) infants have survived worldwide. However, few data have been reported from China. This study was designed to investigate the short-term outcomes of EP infants at discharge in Guangdong province.

CD64 Expression on Polymorph Nuclear Cells as a Sensitive and Specific Diagnostic Biomarker for Neonate Pneumonia.

Background: Neonatal pneumonia (NP) is one of the major causes of neonatal death. Current NP diagnosis depends on a detailed history, physical examination, and radiographic and laboratory findings. There is no specific biomarker or diagnostic indicator of NP.

Comparison of the mydriatic effects of mydrin-P and compound tropicamide in the screening of retinopathy of prematurity.

Purpose: To observe and compare the effects of pupil dilation between Mydrin-P and compound tropicamide in the screening of retinopathy of prematurity.

Methods: The right eyes of premature infants received My- drin-P eye drops as the treatment group, whereas the left eyes were administered with compound tropicamide as the control group. The eye drops were delivered every 5 min for three times.

[Relationship between serum levels of insulin-like growth factor I and growth hormone and neonatal hypoxic-ischemic encephalopathy].

Objective: To study the serum levels of insulin-like growth factor I(IGF-I)and growth hormone (GH) in neonates with hypoxic-ischemic encephalopathy (HIE) and to investigate the relationship of serum levels of IGF-I and GH with the severity of HIE.

Methods: Serum levels of IGF-I and GH were measured within 72 hrs (acute stage) and on the 26-28th days (convalescence stage) of life in 53 HIE neonates. There were 30 babies in the mild HIE group, 15 babies in the moderate HIE group, and 9 babies in the severe HIE group.
