Determine the Effectiveness of Non Word Repetition Task on Some Language Indicators in Children with Specific Language Impairment

Objective: In recent years many papers have emphasized on the relationship between specific language impairment (SLI) and significant weakness in non word repetition task (NRT). The purpose of this study is to examine the effectiveness of NRT training on some related linguistic indicators in children with SLI. Materials & Methods: In this single subject study with multiple baselines examine the effect of NRT training on some language indicators, in four available children with SLI aged 6/6 to7/6. The language indicators include mean length of utterance (MLU), the percent of content morphemes, inflectional morphemes and grammatical morphemes. In order to determine the effect of NRT training, effect size index was applied. Results: The effect sizes of MLU in all of them were high. This training also increased the percent of content morphemes in three subjects. Although it had no effect on one of them. Training made grammatical morphemes increase in three subject but it decrease in one them. Finally Three subjects showed decrease on the index of inflectional morphemes and one of them showed increase. Conclusion: considering effect size, it seems that NRT training improves language indicators in SLI group. As conclusion NRT training would be recommended for SLI group. Key words: specific language impairment/ verbal working memory (phonological loop)/ non word repetition task/ Mean Length of Utterance/ morphology/ terac

Preventing preterm birth in high-risk pregnant women: cerclage or Pessary? A retrospective cohort study

Although preterm birth is considerably more prevalent in pregnant women with a history of previous preterm birth, there is no universal consensus on how to prevent preterm birth in high-risk pregnant women individually. Pessary and cerclage are currently among the two main approaches for preventing preterm birth; however, each method's effectiveness in different high-risk pregnant women is relatively unknown. Therefore, the present study compared the use of cerclage and pessary as methods to prevent preterm birth in high-risk pregnant women. In the current retrospective cohort study, data regarding 88 high-risk pregnant women who were admitted to Kamali Hospital, Karaj, Iran, and had short cervical lengths were collected. Each pregnant woman was either implanted with a pessary or had a cerclage performed. Regression modeling was performed to adjust for the possible confounders, and the odds of preterm birth before the 37th week in each treatment group was calculated. The regression modeling showed that pregnant women who received a pessary implant had lower odds of preterm birth (OR=0.3, 95%CI= 0.1-0.9, p<0.05). Age, gestational age, and cervical length at the time of receiving treatment were considered as the confounding variables. The present study shows that pessary is a more effective method for preventing preterm birth in high-risk pregnant women with cervical lengths ≤25 mm in comparison to the cerclage
