Our findings suggest that many essential surgical interventions are cost-effective or very cost-effective in resource-poor countries. Quantification of the economic value of surgery provides a strong argument for the expansion of global surgery's role in the global health movement. However, economic value should not be the only argument for resource allocation--other organisational, ethical, and political arguments can also be made for its inclusion.

LMICs face many surgical challenges that require innovation. Laparoscopic surgery may be safe, effective, feasible, and cost-effective in LMICs, although it often remains limited in its accessibility, acceptability, and quality. This study may not capture articles written in languages other than English or in journals not indexed by the included databases. Surgeons, policymakers, and manufacturers should focus on plans for sustainability, training and retention of providers, and regulation of efforts to develop laparoscopy in LMICs.

Rotifers of Class Bdelloidea are abundant freshwater invertebrates known for their remarkable ability to survive desiccation and their lack of males and meiosis. Sequencing and annotation of approximately 50-kb regions containing the four hsp82 heat shock genes of the bdelloid Philodina roseola, each located on a separate chromosome, have suggested that its genome is that of a degenerate tetraploid. In order to determine whether a similar structure exists in a bdelloid distantly related to P. roseola and if degenerate tetraploidy was established before the two species separated, we sequenced regions containing the hsp82 genes of a bdelloid belonging to a different family, Adineta vaga, and the histone gene clusters of P. roseola and A. vaga. Our findings are entirely consistent with degenerate tetraploidy and show that it was established before the two bdelloid families diverged and therefore probably before the bdelloid radiation.

Using a CHW-led intervention, women at high risk for developing cervical cancer were identified and navigated to preventive care. Therefore, pairing CHWs with HPV self-sampling is a promising strategy to combat cervical cancer in rural Haiti and similar settings.

Two agents, pigeon pea and lime juice, may contribute to risk for HPV infection in this population. Results suggest that in addition to cervical cancer screening interventions, future preventive initiatives should focus on minimizing risk by advocating for the use of less-toxic twalet deba alternatives.
