Identify patient subgroups defined by trajectories of pain and disability following surgery for degenerative lumbar spinal stenosis, and investigate the construct validity of the subgroups by evaluating for meaningful differences in clinical outcomes. ⋯ Subgroups of patients with degenerative lumbar spinal stenosis can be identified by their trajectories of pain and disability following surgery. Although most patients experienced important reductions in pain and disability, 29% to 42% of patients were classified as members of an outcome trajectory subgroup that experienced little to no benefit from surgery. These findings may inform appropriate expectation setting for patients and clinicians and highlight the need for better methods of treatment selection for patients with degenerative lumbar spinal stenosis.

Observational Study
A validation of the PAWPER XL-MAC tape for total body weight estimation in preschool children from low- and middle-income countries.
The PAWPER tape system is one of the three most accurate paediatric weight estimation systems in the world. The latest version of the tape, which does not rely on a subjective assessment of habitus, is the PAWPER XL-MAC method which uses length and mid-arm circumference (MAC) to estimate weight. It was derived and validated in a population in the USA and has not yet been fully validated in a population from a resource-limited setting. ⋯ The PAWPER XL-MAC tape performed well in this study and was statistically significantly more accurate than both the Broselow tape editions and the Ralston method. This difference was substantial and clinically important. The tape did not perform as well at extremes of habitus-type, however, and might benefit from recalibration.

Frontline providers around the world deliver emergency care daily, often without prior dedicated training. In response to multiple country requests for open-access, basic emergency care training materials, the World Health Organization (WHO), in collaboration with the International Committee of the Red Cross (ICRC) and the International Federation for Emergency Medicine (IFEM), undertook development of a course for health care providers-Basic Emergency Care: Approach to the acutely ill and injured (BEC). As part of course development, pilots were performed in Uganda, the United Republic of Tanzania, and Zambia to evaluate course feasibility and appropriateness. Here we describe participant and facilitator feedback and pre- and post-course exam performance. ⋯ This pilot demonstrates that a low-fidelity, open-access course taught by local instructors can be successful in knowledge transfer. The BEC course was well-received and deemed context-relevant by pilot facilitators and participants in three East African countries. Further studies are needed to evaluate this course's impact on clinical practice and patient outcomes.

Interest in public engagement with science activities has grown in recent decades, especially engagement through social media and among graduate students. Research on scientists' views of engagement, particularly two-way engagement and engagement through social media, is sparse, particularly research examining graduate students' views. ⋯ Graduate students, however, have somewhat more optimistic views of engagement through social media and on the appropriateness of discussing science controversy on social media. We discuss implications for graduate education and future engagement.
