Exploring the drivers of variation in trophic mismatches: A systematic review of long-term avian studies.

Ecol Evol 2021 May 20;11(9):3710-3725. Epub 2021 Mar 20.

NIOZ Royal Netherlands Institute for Sea Research Den Burg The Netherlands.

Many organisms reproduce in seasonal environments, where selection on timing of reproduction is particularly strong as consumers need to synchronize reproduction with the peaked occurrence of their food. When a consumer species changes its phenology at a slower rate than its resources, this may induce a trophic mismatch, that is, offspring growing up after the peak in food availability, potentially leading to reductions in growth and survival. However, there is large variation in the degree of trophic mismatches as well as in its effects on reproductive output. Read More

Combined Liposuction and Physiologic Treatment Achieves Durable Limb Volume Normalization in Class II-III Lymphedema: A Treatment Algorithm to Optimize Outcomes.

Ann Plast Surg 2021 May;86(5S Suppl 3):S384-S389

From the Division of Plastic and Reconstructive Surgery, Stanford University, Palo Alto, CA.

Introduction: Outcomes of surgical lymphedema treatment are currently suboptimal. Physiologic procedures including lymphovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT) reestablish lymphatic flow but cannot correct fibroadipose deposition, whereas liposuction alone cannot prevent disease progression. We propose a treatment algorithm combining liposuction with LVA or VLNT that can achieve normal limb volumes and prevent disease progression in stage II-III lymphedema. Read More

Respir Care 2021 May 10. Epub 2021 May 10.

Department of Anesthesia and Perioperative Care. University of California, San Francisco at Zuckerberg San Francisco General Hospital and Trauma Center, San Francisco, California.

Corona virus disease 2019 (COVID-19) represents the greatest medical crisis encountered in the young history of critical care and respiratory care. During the early months of the pandemic, when little was known about the virus, the acute hypoxemic respiratory failure it caused did not appear to fit conveniently or consistently into our classification of acute respiratory distress syndrome (ARDS). This not only re-ignited a half-century's long simmering debate over taxonomy, but also fueled similar debates over how PEEP and lung-protective ventilation should be titrated, as well as the appropriate role of non-invasive ventilation in ARDS.
