The Amazon floodplain is home to an extremely high diversity of fish, with lakes playing an important role in the establishment of this biological richness. These lacustrine environments are subject to constant fluctuations caused by the annual flood pulse, with local factors and other regional patterns also contributing to the variation in fish community structure. The present study verified how local (depth and transparency of the water, the size and species composition of the macrophyte stands) and regional factors (spatial distribution of the stands and the hydrological phase) influence the structure of the fish community of the floodplain lakes of the Môa River, in northern Brazil.

- The study investigated how children of non-depressed mothers performed better on developmental tests at age 3 compared to those with depressed mothers, focusing on a sample from Brazil.
- Analysis involved assessing maternal depression and children's development over three years using established measurement tools.
- Results showed that persistent maternal depression negatively impacted child development, highlighting the need to prioritize the identification of women at risk for depression in maternal and child health initiatives.
Tracheal replacement with a bioengineered tracheal substitute has been developed for long-segment tracheal diseases. The decellularized tracheal scaffold is an alternative for cell seeding. It is not defined if the storage scaffold produces changes in the scaffold's biomechanical properties.

Aim: Our aim was to investigate the course of depression in the first 2 years postpartum among Brazilian women enrolled in a cash transfer program.

Article Synopsis
- The study aimed to examine factors linked to postpartum depression among mothers from socially vulnerable families in Brazil, utilizing data from a randomized trial involving over 3,200 children under 12 months.
- Out of 3,174 mothers assessed, 26.5% exhibited depressive symptoms, with higher parity (having multiple previous pregnancies) significantly increasing the likelihood of depression.
- Protective factors against postpartum depression included higher educational levels for both parents, support during pregnancy, and having a partner present.
