Mental Health Services for Serious Mental Illness: Scoping Review of Randomised Controlled Trials.

Aims: This review aims to classify the evidence from randomised controlled trials (RCTs) on mental health services (MHS) for people with serious mental illness (SMI) available in the Cochrane Schizophrenia Group's (CSzG) specialised register.

Design: Scoping review.

Methods: We retrieved and screened RCTs of service-level interventions considering non-pharmacological approaches for mental healthcare of the CSzG register.

General concepts on health economic evaluations.

Health economics is an area of study that has critical tools for evidence-based healthcare decision making, among which are economic evaluations. These tools allow us to weigh the costs incurred for a given intervention in relation to its health outcomes. The main utility of these studies lies in accomplishing decision-making in healthcare and the formulation of public policies.

Molecular Evolution of Malacostracan Short Wavelength Sensitive Opsins.

Investigations of the molecular mechanisms behind detection of short, and particularly ultraviolet, wavelengths in arthropods have relied heavily on studies from insects due to the relative ease of heterologous expression of modified opsin proteins in model organisms like Drosophila. However, species outside of the Insecta can provide information on mechanisms for spectral tuning as well as the evolutionary history of pancrustacean visual pigments. Here we investigate the basis of spectral tuning in malacostracan short wavelength sensitive (SWS) opsins using phylogenetic comparative methods.

Oxidative damage associated with exposure to heavy metals present in topsoils in central Chile.

Exposure to heavy metals may cause the overproduction of reactive oxygen species, generating oxidative stress and consequently, various harms to human health. The soil surrounding the Ventanas Industrial Complex, in Puchuncaví and Quintero municipal districts on the central Chilean coast, contains heavy metal concentrations (As, Cu, Pb, Zn, among others) that far exceed the maximum permissible levels established by Italian soil standards (used as a reference). This study aimed to investigate the potential association between heavy metal exposure in humans and the levels of oxidative stress biomarkers in inhabitants of these locations.

Methodological and users' surveys on the use of the LILACS database in Cochrane reviews identified desirable improvements to the database.

Background: Latin American and Caribbean Health Sciences Literature (LILACS) is the main reference database in the region; however, the way in which this resource is used in Cochrane systematic reviews has not been studied.

Objectives: To assess the search methods of Cochrane reviews that used LILACS as a source of information and explore the Cochrane community's perceptions about this resource.

Methods: We identified all Cochrane reviews of interventions published during 2019, which included LILACS as a source of information, and analysed their search methods and also ran a survey through the Cochrane Community.
