Expeditious urbanization and population rise around the globe has fostered the need of speedy and efficient construction, thus generating immense pressure on the construction industry to introduce an efficacious construction technique. The issue can be addressed by precast technology, which is advantageous over conventional monolithic construction in regards to speed, safety, and quality control along with reduced construction cost on mass scale production. However, precast reinforced concrete (RC) buildings have experienced severe damage during the past earthquakes, attributed to seismic behavior of connections between components. Thus, it is of utmost importance to improve the joint connection details and deploy seismic resisting features in precast buildings, such as provision of precast shear walls. Researchers across the world have performed extensive experimental studies to evaluate the response of precast RC walls under lateral loading. This paper reviews on general concepts, codal provisions, precast RC wall connections, review of experimental findings, and effect of post‐tensioning on precast RC walls.

Every child receiving treatment for cancer should be evaluated for possible CINV. Their treatment should take into account the emetogenic potential of the chemotherapeutic drugs. Newer antiemetic drugs have good efficacy and can be tried in pediatric patients, especially in children > 11 years of age.

Objective: Despite evidence that excessive screen use may contribute to negative health, developmental, emotional, and behavioral outcomes, more children are engaging in increasing amounts of screen-related activities. For children with neurodevelopmental conditions, increased screen use could exacerbate emotional/behavioral difficulties (EBDs) by interfering with sleep quantity and quality. Aims: This study examined the possible mediating role of sleep in the relationship between screen use and EBDs in preschool children with neurodevelopmental disorders (NDDs) clinically referred to a child development center in Singapore. Methods: A screen use questionnaire developed for the purposes of the present study, the Children's Sleep Habits Questionnaire, and the Strengths and Difficulties Questionnaire were completed by 367 caregivers of 2- to 5-year-old children with NDDs (39.5% autism spectrum disorder; 36.8% speech-language disorders; 23.7% others). Results: Average daily screen use duration was 3.98 hours, with 93.9% exceeding 1 hour of screen time daily. 57.7% of children had screen devices in their bedrooms, while 52% commenced screen use at the age of 18 months or earlier. Sleep problems fully mediated the relationship between the number of bedroom screen devices and children's EBDs, as well as between the age of first screen use and EBDs, but not between hours of screen use and EBDs. Controlling for age, developmental level, and family income, children who started using screens earlier than 18 months and who had screen devices in their bedrooms had significantly more sleep problems and EBDs than those without. Conclusion: Children with neurodevelopmental conditions may have more difficulties disengaging from screen devices in their bedrooms, and an earlier age of screen exposure may contribute to more chronic disruption of sleep.

A severe episode of dystonia refractory to standard drug therapy has been labeled as status dystonicus or dystonic storm. We report the development of this complication in a 10-year old boy with idiopathic torsion dystonia, the probable precipitating factor being either an infection or introduction of clonazepam.
