Hyperglycemia is an important risk factor for ROP that can be prevented along with other risk factors by accurate supervision.

Introduction: Women with high-risk pregnancy are at increased risk of depression and anxiety during pregnancy, as well as a less favorable parent-infant interaction. This study aimed to investigate the effect of midwife-led psycho-education intervention on parental stress, competency, and postpartum depression in nulliparous women hospitalized with high-risk pregnancy. Methods: This randomized controlled trial was carried out on 66 nulliparous women admitted to the high-risk pregnancy ward of Kamali Hospital, Karaj, Iran. Using convenient sampling method, the mothers were randomly assigned to control and intervention groups. In addition to routine care, the intervention group received four sessions of midwife-led psycho-education intervention in two group sessions in pregnancy and two individual sessions immediately after delivery. The parental stress, parental competency, and postpartum depression questionnaires were used for data collection before, after, and one month after the intervention. Data were analyzed using SPSS software ver. 13.0. Repeated-measures ANOVA test was used for comparing the mean scores of parenting stress, parental competency, and depression between and within both study groups before, after, and one month after delivery. Results: While postpartum depression and parental stress decreased in intervention group, parental competency increased. Conclusion: Our findings indicated that midwife-led psycho-education was effective on parental stress, competency, and postpartum depression in high-risk pregnancy mothers. Accordingly, prenatal distress in high-risk pregnancies should be assessed routinely.

Background Vitamin D deficiency and insufficiency is common in mothers and infants. The present study was conducted with the aim of association between the level of vitamin D in the mother’s serum and the level of vitamin D in the serum of preterm infants. Method The present descriptive – analytical study was performed on 140 mothers and preterm infants referred to the Kamali hospital in Alborz University of Medical Sciences. Sampling was done from available mothers after hospitalization for delivery and their infants during the first 72 hours after delivery. Information from mothers and infants were collected with researcher made check list, including age, type of delivery, number of pregnancies, vitamin D during this pregnancy, infants birth age, gender, and birth weight. Data analysis was performed using SPSS version 24 software. Results The average age of mothers was 28 ± 5 years and the average age of infants at the time of birth was 30 ± 1 weeks. Forty two infants (67%) were boys and 23 infants (33%) were girls. The results showed a high rate of vitamin D insufficiency and deficiency in mother (44, 49%) and preterm infants (49, 38%). The results of the Pearson correlation test showed that there is a strong and significant relationship between the serum vitamin D level of mothers and preterm infants (P = 0.001). Logistic regression tests showed that mother’s vitamin D level had an effect on the infant’s vitamin D level. Conclusion Considering high rate of vitamin D deficiency and insufficiency and relationship between vitamin D in preterm infants serum and mothers, diagnostic screenings are recommended to investigate vitamin D disorders in pregnant mothers, which should be planned, implemented and followed up in the form of a therapeutic program to prevent the occurrence of complications caused by this disorder in the mother and infant.

Background Internet addiction has become more prevalent in Adolescents. Some adolescents who tend to use Internet excessively have a poorer health status, and engage in more risky behaviors than others. Therefore, the aim of this study was to investigate the predictor role of Internet addiction in high- risk behaviors and the general health status among adolescences. Methods This was a descriptive-analytical study of structural equation modeling, conducted on 300 students of Alborz University of Medical Sciences. The multi-stage sampling method was used to identify the number of students aged 19–21 years studying in each faculty in the first stage and convenience sampling was used in the second stage. Data were collected using Iranian Adolescents Risk-taking Scale (IARS), the General Health Questionnaire (GHQ-28) and the Young's Internet Addiction Test (YIAT). The data were analyzed using LISREL version 8.8. Results The results of the measurement model using LISREL software showed a goodness of fit for the conceptual model. Internet addiction had a significant direct positive effect on the adolescents' high-risk behaviors (β = 0.17). Also, Internet addiction had a significant positive effect on the adolescents' general health status (β = 0.33) and general health problems increased by 0.33 per unit of Internet use. The result of structural model revealed no significant effects of general health on high-risk behaviors. Based on the value of the variance determined, Internet addiction could predict 11% of general health. Also, general health and Internet addiction together could predict 2.7% of high- risk behaviors. Conclusion Given the effect of Internet addiction on the general health and high-risk behavior, it is recommended that adolescents will be screened about internet addiction and the necessary training is given to the adolescents on the appropriate use of Internet. All necessary information should be given to the parents regarding Internet risks and dangers.
