The Pathway Interaction Database (PID, http://pid.nci.nih.gov) is a freely available collection of curated and peer-reviewed pathways composed of human molecular signaling and regulatory events and key cellular processes. Created in a collaboration between the US National Cancer Institute and Nature Publishing Group, the database serves as a research tool for the cancer research community and others interested in cellular pathways, such as neuroscientists, developmental biologists and immunologists. PID offers a range of search features to facilitate pathway exploration. Users can browse the predefined set of pathways or create interaction network maps centered on a single molecule or cellular process of interest. In addition, the batch query tool allows users to upload long list(s) of molecules, such as those derived from microarray experiments, and either overlay these molecules onto predefined pathways or visualize the complete molecular connectivity map. Users can also download molecule lists, citation lists and complete database content in extensible markup language (XML) and Biological Pathways Exchange (BioPAX) Level 2 format. The database is updated with new pathway content every month and supplemented by specially commissioned articles on the practical uses of other relevant online tools.

Data from 368 families of children with autism and other developmental disabilities in the People's Republic of China were gathered to understand the stresses that families experience and the coping strategies they employ. Chinese families of children with developmental disabilities perceived high levels of stress related to pessimism, child characteristics, and parent and family problems. Regarding coping strategies, acceptance, active coping, positive reinterpretation and growth, suppression of competing activities, and planning were the most frequently employed coping strategies. Parents of children with autism experienced more stress and used planning as a coping strategy to a greater degree than parents of children with other developmental disabilities. The implications and limitations of these findings are discussed.

Tumour stage helped explain socio-economic disparities in colorectal cancer survival. Disparities were also greatly attenuated among patients receiving early treatment. Aspects other than those captured by our measure of access, such as quality of care and patient preferences in relation to treatment, might contribute to a fuller explanation.

The COVID-19 pandemic has brought about an urgent need for effective treatment, while conserving vital resources such as intensive care unit beds and ventilators. Antivirals, convalescent plasma, and biologics have been used with mixed results. The profound “cytokine storm” induced endotheliopathy and microthrombotic disease in patients with COVID-19 may lead to acute respiratory distress syndrome, sepsis, and multi-organ failure. We present a case of SARS-COV2 pneumonia with septic shock and multi-organ failure that demonstrated significant clinical improvement after therapeutic plasma exchange. A 65-year-old female with multiple comorbidities presented with progressive dyspnea and dry cough. She was found to be COVID-19 positive with pneumonia, and developed progressive hypoxemia and shock requiring vasopressors, cardioversion, and non-invasive positive pressure ventilation. Given her worsening sepsis with multi-organ failure, she underwent therapeutic plasma exchange with rapid clinical improvement. Her case supports the theory that plasma exchange may help abate the “cytokine storm” induced endotheliopathy and microthrombosis associated with COVID-19. Further studies are needed to identify markers of this pathway and the potential role of plasma exchange in these critically ill patients.
