Ecological dynamics explain modular denitrification in the ocean.
Proc Natl Acad Sci U S A

Microorganisms in marine oxygen minimum zones (OMZs) drive globally impactful biogeochemical processes. One such process is multistep denitrification (NO→NO→NO→NO→N), which dominates OMZ bioavailable nitrogen (N) loss and nitrous oxide (NO) production. Denitrification-derived N loss is typically measured and modeled as a single step, but observations reveal that most denitrifiers in OMZs contain subsets ("modules") of the complete pathway.

However, with changing anaesthetic and perioperative management, there is ongoing uncertainty about the importance of OSA as a risk factor for post-operative complications.
Methods: A cohort study involving subjects undergoing elective surgery was conducted.
Background: Breastfeeding support interventions are associated with longer breastfeeding duration. Contemporary nationally representative data on breastfeeding support as reported by women in England is lacking. Using English national maternity survey data, we describe sources and modes of breastfeeding support as reported by women who gave birth in 2020; sources of support are compared with earlier maternity surveys (2014, 2016, 2018).

Study Design: This is a retrospective, observational study of umbilical cord tissue THC levels in a single center, comparing THC exposure rates and concentration levels before and after cannabis legalization in the state of Illinois, Epoch 1 (October 1, 2018-June 30, 2019, pre-legalization) and Epoch 2 (July 1, 2019-August 31, 2021, post-legalization).
Results: A total of 811 umbilical cords were analyzed during epoch 1 and 2,170 during epoch 2.
Article Synopsis
- The American Society of Pain and Neuroscience (ASPN) recognizes a need for guidelines to help healthcare providers effectively use social media for best practices.
- A panel of experts conducted research and analyzed literature to develop these best practices for healthcare professionals engaging online.
- It's essential for providers to understand the impact of social media on patient perceptions and to navigate legal and ethical issues while maintaining a clear and educational online presence.
