Article Synopsis
- There has been a global increase in Harmful Algae Blooms (HABs) over recent decades, linked to environmental exploitation, enhanced monitoring, and rising maritime transport.
- HAB species, such as those causing paralytic shellfish poisoning and producing yessotoxins, pose serious public health and socioeconomic risks.
- Recent observations in the Biobio region suggest a northward movement of these HABs into more open waters, with studies indicating that factors like deep-water turbulence and the presence of toxic resting cysts could trigger harmful events in the environment.
Protoceratium reticulatum is the main yessotoxin-producer along the Chilean coast. Thus far, the yessotoxin levels recorded in this region have not posed a serious threat to human health. However, a bloom of P.

- In late summer 2020, a moderate harmful algal bloom was found in the Pitipalena-Añihue Marine Protected Area, raising concerns about potential fish kills, particularly in salmon populations.
- The bloom coincided with a decline in monitoring activities due to COVID-19 lockdowns, as previous harmful events in the region had primarily impacted offshore waters before reaching coastal areas.
- Environmental factors, like reduced rainfall and warm surface water, contributed to the bloom's behavior, and a proposed model suggested that local ocean currents and thermal fronts in the area may lead to the accumulation of harmful species.
Inflammatory bowel disease (IBD) occurring following allogeneic stem cell transplantation (aSCT) is a very rare condition. The underlying pathogenesis needs to be better defined. There is currently no systematic effort to exclude loss- or gain-of-function mutations in immune-related genes in stem cell donors.

However, the effects of climate change will not be distributed equally, and Chile has emerged as one important, vulnerable area. The Chilean Patagonian region (41‒56°S) hosts two marine ecoregions that support robust blue economies via wild fisheries, aquaculture, and tourism.
