Noncommunicable diseases, including those requiring surgical care, are increasingly straining low- and middle-income countries. Globally, 11% of all disability-adjusted life-years lost result from conditions requiring surgery; however, little is known about country-specific burden. We piloted a household-based survey in a periurban district of Uganda to estimate the prevalence of surgical conditions and to identify logistical challenges. ⋯ In this setting, the current prevalence of surgical conditions was nearly 1 in 10 persons, and lifetime occurrence was high, at 1 in 4 persons. Addressable challenges led to question revisions and a change in the data collection platform. A full-country study is both feasible and necessary to characterize the met and unmet need for surgical care in Uganda.

There is currently little information regarding the impact of procedure volume on outcomes after open inguinal hernia repair in the United States. Our hypothesis was that increasing procedure volume is associated with lesser rates of reoperation and resource use. ⋯ Surgeon volume <25 cases per year for open inguinal hernia repair was independently associated with greater rates of reoperation for recurrence, worse operative efficiency, and greater health care costs. Referral to surgeons who perform ≥25 inguinal hernia repairs per year should be considered to decrease reoperation rates and resource use.

Propranolol has been shown previously to decrease the mobilization of hematopoietic progenitor cells (HPCs) after acute injury in rodent models; however, this acute injury model does not reflect the prolonged period of critical illness after severe trauma. Using our novel lung contusion/hemorrhagic shock/chronic restraint stress model, we hypothesize that daily administration of propranolol will decrease prolonged mobilization of HPCs without worsening lung healing. ⋯ The daily administration of propranolol after both lung contusion and lung contusion/hemorrhagic shock subjected to chronic restraint stress decreased the prolonged mobilization of HPC from the bone marrow and decreased plasma G-CSF levels. Despite the decrease in mobilization of HPC, lung healing did not worsen. Alleviating chronic stress with propranolol may be a future therapeutic target to improve healing after severe injury.
