Anxiety and depression in parents of sick neonates: a hospital-based study.

AIMS AND OBJECTIVES: To investigate the prevalence of anxiety and depression in parents of hospitalised neonates and to analyse their relationship with other factors such as stress and social support, to provide evidence for targeted clinical interventions. BACKGROUND: The perinatal period, a special susceptibility to negative emotions, is a period that women and their spouses have to face. In this time, the fact that the neonates have to be hospitalised is no doubt a huge psychological stress to their parents. Little understanding of the hospitalisation environment, lacking awareness of neonatal diseases as well as concerns about the neonates' safety, can easily lead to negative emotions in parents. Under the influence of negative mood, parents could become irritable and vulnerable, which may do harm to their physical and mental health, impact family harmony and even result in ineffective communication with doctors, affecting the care of neonates. DESIGN: This study applied a cross-sectional study design. METHODS: The psychological status of 600 parents (400 fathers and 200 mothers) was assessed in the first week of the hospitalisation of neonates, using the Self-Rating Anxiety Scale, Self-Rating Depressive Scale, Social Support Rating Scale and Perceived Stress Scale. RESULTS: The results of the cross-sectional survey showed that 20% of fathers and 24% of mothers had symptoms of anxiety, while 30.8% of fathers and 35% of mothers had depressive symptoms. The total scores for anxiety and depression in these parents were significantly higher than the normal population (p<0.01). The level of social support and perceived stress were the most important factors relating to parental anxiety and depression. CONCLUSION: Parents of hospitalised neonates are more prone to suffer from negative emotions than normal population. Anxiety and depression are common emotions in these parents. However, the social support they receive is far from satisfactory, so timely and effective nursing interventions are essential. RELEVANCE TO CLINICAL PRACTICE: Health professionals should understand the mental health of parents with hospitalised neonates and take measures to reduce their psychological pressure so as to improve their care of the neonates, and help to maintain the harmony and stability of families and the whole society.

Differential expression profile of MicroRNAs during differentiation of cardiomyocytes exposed to polychlorinated biphenyls.

Exposure to persistent environmental pollutants, such as polychlorinated biphenyls (PCBs), is a risk factor for the development of congenital heart defects. MicroRNAs (miRNAs) have been shown to be involved in cardiac development. The objective of this study was to investigate changes in miRNA expression profiles during the differentiation of cardiomyocytes exposed to PCBs. For that purpose, PCBs (Aroclor 1254) at a concentration of 2.5 µmol/L were added on day 0 of differentiation of P19 mouse embryonal carcinoma cells into cardiac myocytes. The relative expression of miRNA genes was determined by miRNA microarray and real-time reverse transcriptase polymerase chain reaction (real-time RT-PCR) analyses. The microarray results revealed that 45 miRNAs, of which 14 were upregulated and 31 were downregulated, were differentially expressed in P19 cells treated with PCBs compared with control cells. The miRNA expression data was validated with real-time RT-PCR. The expression of certain potential target genes (Wnt1) was found to be reduced in P19 cells treated with PCBs, whereas the expression of other potential predicted target genes (GSK3ß) was increased. Our results demonstrate a critical role of miRNAs in mediating the effect of PCBs during the differentiation of P19 cells into cardiac myocytes.

Long-term consequences of the early treatment of children with congenital hypothyroidism detected by neonatal screening in Nanjing, China: a 12-year follow-up study.

This study was performed to investigate the prevalence of congenital hypothyroidism (CH) in neonates in Nanjing, China and the long-term consequences of early treatment. A total of 442 454 neonates were screened for CH and 183 neonates were confirmed, with a prevalence of 1 in 2418. Of these, 163 neonates completed the follow-up process and 163 healthy children were recruited as the control group. The height, weight and body mass index (BMI) of the children with CH from 0.5 to 6 years were not significantly different from the control group (p > 0.05). The children with CH had a significantly increased risk for being overweight or obese between 0.5 and 6 years (p < 0.05). The children with CH showed a significantly lower developmental quotient (DQ) than the control group in all four areas of the Gesell test (p < 0.05). The results suggest that children with CH that has been identified by newborn screening and early treatment have normal growth and neuromotor development.

[Detection of serum desmoglein antibody level using enzyme-linked immunosorbent assay (ELISA) for monitoring disease activity in patients with pemphigus vulgaris].

OBJECTIVE: Pemphigus is an autoimmune blistering disease of skin and mucous membranes. Pemphigus vulgaris (PV) is a major subtype of pemphigus, which is histologically characterized by suprabasal acantholysis. The major antigen in PV is desmosomal glycoproteins desmoglein (Dsg) 3. The autoantibodies against Dsg3 cause loss of adhesion between keratinocytes. Some PV patients also have circulating anti-Dsg1 autoantibodies. Enzyme-linked immunosorbent assays (ELISAs) with recombinant Dsg3 and Dsg1 are highly sensitive and specific for detecting anti-Dsg3 and anti-Dsg1 autoantibodies in PV patients. To evaluate the role of desmosomal glycoproteins desmoglein (Dsg3) ELISA and Dsg1 ELISA for detecting anti-Dsg3 and anti-Dsg1 autoantibodies in monitoring disease activity in Pemphigus vulgaris patients. METHODS: Twenty PV patients with long-term follow-up were included. We tested their serial sera with modified Dsg3 ELISA (MESACUP Desmoglein TEST "Dsg3", Medical & Biological Laboratories Co. LTD.), Dsg1 ELISA(MESACUP Desmoglein TEST "Dsg1", Medical & Biological Laboratories Co. LTD.) and indirect immunofluorescence (IIF). Then we analyzed the correlation between Dsg3 ELISA index values, Dsg1 ELISA index values, IIF titres and disease activity scores (ABSIS) along the time course. RESULTS: There were significant correlations between Dsg3 ELISA index values, Dsg1 ELISA index values, IIF titres and disease activity scores (both skin scores and oral scores) (P<0.01) along the time course. Significant differences of Dsg3 ELISA index values, Dsg1 ELISA index values and IIF titres between active time-point group and clinical remission time-point group were also observed (P<0.01). We found that Dsg3 ELISA index values, Dsg1 ELISA index values and IIF titres fluctuated in parallel with disease activity, and ELISA index values were superior to IIF titres. CONCLUSION: Dsg3 ELISA index values fluctuating in parallel with disease activity are useful to monitor disease activity, predict flares or relapses and plan the schedules for tapering the drugs.

Transcutaneous bilirubin nomogram for predicting neonatal hyperbilirubinemia in healthy term and late-preterm Chinese infants.

Identifying infants that will develop significant hyperbilirubinemia with the risk of kernicterus, and planning appropriate follow-up strategies, is particularly challenging. In this study, 36,921 transcutaneous bilirubin (TcB) measurements were obtained from 6,035 healthy neonates (gestational age ≥ 35 weeks and birth weight ≥ 2,000 g) between January 1 and December 31, 2009. All measurements were performed with the JM-103 bilirubinometer at designated times between 0 and 168 postnatal hours. TcB percentiles were calculated and used to develop an hour-specific nomogram. The rate of increase in TcB was higher during the first 72 h of age, after which levels declined to a plateau by 72-108 h of age. We constructed a TcB nomogram by using the 40th, 75th, and 95th percentile values of TcB for every 12 h of the studied interval. The 75th percentile curve of the nomogram may be an ideal cutoff point for intensive follow-up of the neonate for hyperbilirubinemia as it carries very high sensitivity (78.7%) and negative predictive value (98.5%). The specificity (45.7%) and positive predictive value (15.5%) decreased to reach their lowest levels at the 40th percentile. Of the neonates in the high-risk zone, 167 (48.8%) infants had persistent subsequent hyperbilirubinemia post-discharge, compared with 292 (27.0%) infants in the high-intermediate-risk zone at discharge. One-hundred and seventeen (5.5%) infants in the low-intermediate-risk zone moved into the high-risk zone during follow-up. No newborn infants in the low-risk zone became high-risk during follow-up. We provide an hour-specific TcB nomogram to predict neonatal hyperbilirubinemia in healthy term and late-preterm Chinese infants.
