“…Among them, bacterial infection is the major cause leading to jaundice ( 6 ). Neonatal bacterial infection can be triggered by a couple of high-risk factors such as premature rupture of membranes, contamination of amniotic fluid, and maternal vaginal infections during delivery ( 7 ). Infection can cause premature destruction of red blood cells of the newborn to varying degrees, resulting in hemolytic symptoms.…”

Background: To evaluate changes of associated markers in neonatal pathological jaundice due to bacterial infection in newborns, to provide an experimental basis for early diagnosis and treatment of neonatal pathological jaundice. Methods: A total of 126 newborns with neonatal pathological jaundice in the Pediatrics Department of Qilu Hospital (Qingdao), Cheeloo College of Medicine, Shandong University from Jan 2016 to Jun 2018 were enrolled. The patients were divided into bacterial infection group (76 cases with combined bacterial infection) and non-infection group (50 cases without bacterial infection). Peripheral blood was drawn from patients, and levels of inflammatory factors, levels of indexes of liver function and levels of cardiac markers were detected. Correlation between inflammatory factors and neonatal pathological jaundice was assessed. Results: The levels of WBC, hs-CRP and PCT in the bacterial infection group were significantly higher than those in the non-infected group (P<0.05). The level of TRF in the bacterial infection group was significantly lower than that in the non-infection group (P<0.01). In the bacterial infection group, the levels of WBC, hs-CRP, PCT, and TRF were positively correlated with the levels of CK, CKMB, LDH, and α-HBDB, respectively (all P<0.05). The TRF level after treatment was significantly higher than that before treatment (P<0.01). Conclusion: Markers such as WBC, hs-CRP, PCT, and TRF can be used as effective indicators in diagnosis of pathological jaundice due to bacterial infection in newborns. The combined testing of WBC, hs-CRP, PCT, and TRF was helpful for early diagnosis and early clinical intervention of neonatal pathological jaundice, which can lower the risk of clinical complications.

“…We detected the threshold at minimum response levels in each frequency in both ears and 2 modulation rates of 40 and 80 Hz, separately. Both amplitude and frequency modulation were applied for stimulus at depths of 80 and 20, respectively ( Jafari et al, 2009 ; Panahi, Jafari, & Hasani, 2014 ).…”

Introduction:Mild Cognitive Impairment (MCI), a disorder of the elderly people, is difficult to diagnose and often progresses to Alzheimer Disease (AD). Temporal region is one of the initial areas, which gets impaired in the early stage of AD. Therefore, auditory cortical evoked potential could be a valuable neuromarker for detecting MCI and AD.Methods:In this study, the thresholds of Auditory Steady-State Response (ASSR) to 40 Hz and 80 Hz were compared between Alzheimer Disease (AD), MCI, and control groups. A total of 42 patients (12 with AD, 15 with MCI, and 15 elderly normal controls) were tested for ASSR. Hearing thresholds at 500, 1000, and 2000 Hz in both ears with modulation rates of 40 and 80 Hz were obtained.Results:Significant differences in normal subjects were observed in estimated ASSR thresholds with 2 modulation rates in 3 frequencies in both ears. However, the difference was significant only in 500 Hz in the MCI group, and no significant differences were observed in the AD group. In addition, significant differences were observed between the normal subjects and AD patients with regard to the estimated ASSR thresholds with 2 modulation rates and 3 frequencies in both ears. A significant difference was observed between the normal and MCI groups at 2000 Hz, too. An increase in estimated 40 Hz ASSR thresholds in patients with AD and MCI suggests neural changes in auditory cortex compared to that in normal ageing.Conclusion:Auditory threshold estimation with low and high modulation rates by ASSR test could be a potentially helpful test for detecting cognitive impairment.

“…30 However, there is evidence that even low levels of bilirubin may still lead to minor encephalopathy, especially in newborns with high risk factors. 31 Premature infants are very vulnerable to bilirubin due to their own characteristics; it can cause neurological damage, even in cases where bilirubin levels are very low. 28 Premature infants are more prone to metabolic disorders, hypoxic–ischemic events and infection, causing an increase in the permeability of the blood–brain barrier and the level of bilirubin in the nervous system, thus independently causing neuronal damage, and the oxidative stress of bilirubin further aggravates the damage of neurons.…”

Change to Hearing Loss–Related Risks and Screening in Preterm Infants

Hearing loss is one of the most common congenital defects in infancy; it increases speech and language delays and adversely affects academic achievement and socialemotional development. The risk of hearing loss in premature infants is higher than that in normal newborns, and because of the fragility of the auditory nervous system, it is more vulnerable to different risk factors. The hearing screening guidelines in current use were proposed by the American Academy of Pediatrics and updated in 2007, but there are no uniform guidelines for hearing screening in preterm infants. This review focuses on the risk factors related to hearing loss in premature infants, hearing screening strategies, and reasons for failure. The aim is to provide a more comprehensive understanding of hearing development in preterm infants to achieve early detection and early intervention. At the same time, attention should be paid to delayed auditory maturation in preterm infants to avoid excessive intervention. Key Points
