The protective and destructive critical processes of female labor in small-scale fishing in coast Pernambuco, Brazil.

This study aims to analyze the protective and destructive critical processes of 34 water women in the municipalities of Cabo de Santo de Agostinho and Ipojuca, Pernambuco, Brazil, from February/21 to August/22. The work process stages were systematized by the work flowchart, and we employed Breilh's critical processes matrix to organize the data. The destructive processes identified in the general domain were injustice and socio-environmental vulnerability, such as the economic development model, the Suape Industrial Port Complex, the 2019 oil spill crime disaster, the COVID-19 pandemic, and the difficult access to public policies; in the particular domain: overloads and extended working hours, use of rudimentary equipment and tools, and unequal gender, class, and race relationships; in the singular domain: physical and mental illnesses and deaths.

Redox-associated changes in healthy individuals at risk of Alzheimer's disease. A ten-year follow-up study.

Carrying an allele 4 of the apolipoprotein E (ApoE) is the best-established genetic risk factor to develop Alzheimer's disease (AD). Fifty percent of ApoE4/4 individuals develop the disease at 70 years of age. ApoE3/4 carriers have a lower risk of developing the disease, still 50% of them suffer AD at around 80 years.

Is Sleep Disruption a Cause or Consequence of Alzheimer's Disease? Reviewing Its Possible Role as a Biomarker.

In recent years, the idea that sleep is critical for cognitive processing has gained strength. Alzheimer's disease (AD) is the most common form of dementia worldwide and presents a high prevalence of sleep disturbances. However, it is difficult to establish causal relations, since a vicious circle emerges between different aspects of the disease.

When Does Alzheimer's Disease Really Start? The Role of Biomarkers.

While Alzheimer's disease (AD) classical diagnostic criteria rely on clinical data from a stablished symptomatic disease, newer criteria aim to identify the disease in its earlier stages. For that, they incorporated the use of AD's specific biomarkers to reach a diagnosis, including the identification of Aβ and tau depositions, glucose hypometabolism, and cerebral atrophy. These biomarkers created a new concept of the disease, in which AD's main pathological processes have already taken place decades before we can clinically diagnose the first symptoms.
