Inequalities in COVID-19 impact on preschool mental health in India: key moderators of adverse outcome.

Introduction: Worldwide research suggests that the COVID-19 pandemic had little to no overall effect on preschool children's mental health, but that the impact is variable depending on pre-existing and COVID-19-related inequalities. Evidence from low- and middle-income country settings is sparse, yet effects may be more variable due to greater inequalities. We provide the first empirical evidence for the impact of the pandemic on emotional and behavioural problems in Indian preschool children, after accounting for normative age-related change, and test whether the impact varied depending on COVID-19-related inequalities.

Visual attention and recall of flavored cigarillo package elements among young adults: A randomized control trial.

Introduction: Flavoring in cigarillos contributes to greater product initiation and abuse liability particularly among young adults. Few studies have examined how packaging elements, including flavor, may draw visual attention from potential consumers as well as impact product recall. This study aimed to test the difference in visual attention to flavor names and other packaging elements on cigarillo products as well as recall of these packaging elements.

Chitosan-Based Electronics: The Importance of Acid Strength and Plasticizing Additives on Device Performance.

A rise in demand for disposable consumer electronics such as smart packaging, wearable electronics, and single-use point-of-source sensors requires the development of eco-friendly and compostable electronic materials. Chitosan is derived from crustacean waste and offers high dielectric constant values without requiring rigorous purification, making it sustainable for large-scale electronic device manufacturing. When processed in acidic media, the protonated backbone of chitosan pairs with counterions from the acid dissociation to form chitosan thin films with electrical double layers (EDLs) and tunable capacitive properties.

Complications associated with loop ileostomy reversal delayed greater than twelve months.

Diverting loop ileostomy is performed after colectomy to allow for anastomotic healing, and prevention of pelvic sepsis when an anastomotic leak occurs. There is no consensus on the optimal timing of ileostomy closure, and there is limited data on complications associated with ileostomy closure greater than 12 months after creation. The aim of this study is to investigate outcomes of delayed loop ileostomy closure greater than 12 months after creation.
