As marine heatwaves and mass coral bleaching events rise in frequency and severity, there is an increasing need for high-resolution satellite products that accurately predict reef thermal environments over large spatio-temporal scales. Deciding which global sea surface temperature (SST) dataset to use for research or management depends in part on the desired spatial resolution. Here, we evaluate two SST datasets - the lower-resolution CoralTemp v3.

Alcohol Clin Exp Res (Hoboken)
January 2025
Background: Alcohol use is measured in diverse ways across settings. Harmonization of measures is necessary to assess effects of alcohol use in multi-cohort collaborations, such as studies of people with HIV (PWH).
Methods: Data were combined from 14 HIV cohort studies (nine European, five North American) participating in the Antiretroviral Therapy Cohort Collaboration.
Article Synopsis
- PTSD negatively impacts the adherence and effectiveness of antiretroviral therapy (ART) in veterans with HIV, leading to increased nonadherence and modifications in treatment.
- This study analyzed over 22,000 person-years of data from veterans who deployed to Iraq and Afghanistan, finding a 6% increase in nonadherence and a 38% increase in ART modifications linked to PTSD.
- Veterans with multiple deployments saw an even greater likelihood of nonadherence; the impact of PTSD on treatment changes was most pronounced in the first decade after diagnosis, highlighting the need for regular PTSD screening in this population.
Article Synopsis
- Marine heatwaves are becoming more frequent and severe due to climate change, putting reef-building corals at risk of mass mortality and increased selective pressure.
- A new eco-evolutionary metapopulation model shows that while corals can somewhat adapt, they will face significant population declines from heatwaves over the next few decades.
- To help sensitive coral populations survive beyond 2050, it's crucial to dramatically reduce greenhouse gas emissions and limit global warming to 2°C instead of the projected 3°C.
Data standards are available for spinal cord injury (SCI). The International SCI Data Sets were created in 2002 and there are currently 27 freely available. In 2014 the National Institute of Neurological Disorders and Stroke developed clinical common data elements to promote clinical data sharing in SCI.
