Child-Focused Mental Health Interventions for Disasters Recovery: A Rapid Review of Experiences to Inform Return-to-School Strategies After COVID-19.

There is a worldwide need for mental health interventions to address the mental health needs of children under 12 who are returning to school in the post-COVID-19 environment. The basic characteristics of child-focused, post-crisis interventions are currently unknown, but they are essential for developing high-quality, expedient RTC programs. We conducted a rapid systematic review, via established PICO methodology, to appraise the characteristics of such interventions. We queried databases (PubMed, PsycInfo, ERIC) for English and Spanish publications describing mental health interventions to reduce mental health symptoms and sequelae among children exposed to disasters and other community crises. We described the following characteristics: type of intervention, length, number of sessions, number of staff delivering the intervention, and other characteristics. A total of 18 original articles met the inclusion criteria: 11 correspond to a controlled trial type of study and 15 addressed PTSD after disaster or crisis situations. Cognitive-behavioral therapy (CBT) was the most common intervention type, school-based/related interventions were the most common method, and five articles described an important role of teachers as mediators of therapy.

Templated electrodeposition and photocatalytic activity of cuprous oxide nanorod arrays.

Cuprous oxide (Cu2O) nanorod arrays have been prepared via a novel templated electrodeposition process and were characterized for their photocatalytic behavior in nonaqueous photoelectrochemical cells. Zinc oxide (ZnO) nanorod films serve as sacrificial templates for the in situ formation of polymer nanopore membranes on transparent conductive oxide substrates. Nitrocellulose and poly(lactic acid) are effective membrane-forming polymers that exhibit different modes of template formation, with nitrocellulose forming conformal coatings on the ZnO surface while poly(lactic acid) acts as an amorphous pore-filling material. Robust template formation is sensitive to the seeding method used to prepare the precursor ZnO nanorod films. Photoelectrochemical cells prepared from electrodeposited Cu2O films using methyl viologen as a redox shuttle in acetonitrile electrolyte exhibit significant charge recombination that can be partially suppressed by a combination of surface passivation methods. Surface-passivated nanostructured Cu2O films show enhanced photocurrent relative to planar electrodeposited Cu2O films of similar thickness. We have obtained the highest photocurrent ever reported for electrodeposited Cu2O in a nonaqueous photoelectrochemical cell.
