The toxic C1 compounds methanol and formaldehyde are generated during bioconversion of lignin into value-added chemicals. These toxins can be detoxified and assimilated by methylotrophs to synthesize useful metabolites and cell biomass. We discuss the promising future of constructing integrated biosystems to use toxic C1 byproducts and promote lignin valorization.Mitigating climate change is a key driver for the development of sustainable and CO2-neutral production processes. In this regard, connecting carbon capture and utilization processes to derive microbial C1 fermentation substrates from CO2 is highly promising. This strategy uses methylotrophic microbes to unlock next-generation processes, converting CO2-derived methanol. Synthetic biology approaches in particular can empower synthetic methylotrophs to produce a variety of commodity chemicals. We believe that yeasts have outstanding potential for this purpose, because they are able to separate toxic intermediates and metabolic reactions in organelles. This compartmentalization can be harnessed to design superior synthetic methylotrophs, capable of utilizing methanol and other hitherto largely disregarded C1 compounds, thus supporting the establishment of a future circular economy.Metabolic engineering (ME) aims to develop efficient microbial cell factories that can produce a wide variety of valuable compounds, ideally at the highest yield and from various feedstocks. Selleck BLU9931 We summarize recent developments in ME methods for tailoring different yeast cell factories (YCFs). In particular, we highlight the most timely and cutting-edge molecular tools and strategies for biosynthetic pathway optimization (including genome-editing tools), combinatorial transcriptional and post-transcriptional engineering (cis/trans regulators), dynamic control of metabolic fluxes (e.g., rewiring of primary metabolism), and spatial reconfiguration of metabolic pathways. Finally, we discuss challenges and perspectives for adaptive laboratory evolution (ALE) of yeast to advance ME of microbial cell factories.
In response to the opioid epidemic, we hypothesized that adequate pain control can be achieved with few, if any, opioid prescriptions at discharge following pediatric surgical procedures.
All records for patients 0-15 years old who underwent pediatric surgical operations from December 2017 through May 2018 were reviewed. Opioids prescriptions, emergency department (ED) visits, and hospital readmissions were recorded. Postoperative pain was assessed on a scale from 0 to 10 via phone call within three days of discharge.
352 patients underwent 394 surgical procedures. Three patients were prescribed opioids at discharge. There were no pain-related readmissions. One patient returned to the ED owing to pain. 116 unique pain scores were obtained from 114 patients score 0 (n = 69, 59%), 1-3 (n = 31, 27%), 4-5 (n = 11, 9%), 6-8 (n = 5, 4%), and 9-10 (n = 0, 0%). There was a positive association between pain and increasing age (r = 0.26, p = 0.005). No patients who underwent hernia repair reported a pain score greater than 3.
Adequate pain control at discharge after pediatric general surgical procedures can be achieved for most children with scheduled nonopioid medications only. A limited supply of opioids for analgesia after discharge may benefit small subset of patients. This strategy would help reduce opioid prevalence in the community.

Intestinal volvulus in a neonate, complete or segmental, is a true surgical emergency, which when the diagnosis is delayed can bring detrimental results. The aim of this study was to describe the clinical characteristics of intestinal volvulus during the neonatal period by comparing total midgut volvulus (TMV) and segmental volvulus (SV).
The medical records of 44 neonates who were operated on for intestinal volvulus from 1993 to 2019 were retrospectively reviewed. The patients were divided into TMV and SV groups, and clinical features were compared.
Operations were performed on 27 patients for TMV and 17 for SV. All cases of TMV were associated with intestinal malrotation, while those with SV were not. Gestational age, birth weight, and ratio of prematurity showed no differences between the groups. Preoperative diagnosis of TMV or SV was possible in 23 and 5 (85% and 29%) cases, respectively. Intestinal resection was required in 16/17 patients (94%) with SV, while it was required in 5/27 (19%) patients with TMV. When bowel resection was performed in TMV, all but one patient suffered from short bowel syndrome leading to two mortalities, while SV group showed good recovery.
Diagnosis of SV before laparotomy can be difficult. Even though performing intestinal resection in SV neonates is highly likely, it shows a favorable outcome. TMV neonates are less likely to undergo intestinal resection; however, when bowel ischemia is present, significant morbidity can occur.

Air transportation can be a life-saving transfer modality for trauma patients. However, it is also costly and carries risk for air-crews and patients. We sought to examine the incidence of air transportation among pediatric trauma patients as well as the rate of over-triage in utilizing this intervention.
We conducted a single-institution retrospective review of all pediatric trauma patients who utilized air transportation, either from scene to hospital or hospital to hospital Emergency Department (ED) transfers, between 2013 and 2018.
There were 348 pediatric trauma patients who utilized air transport. More than half of all patients (n = 186, 55.9%) were discharged from the hospital within 48 h, 121 (36.3%) were discharged within 24 h, and 34 (10.2%) were discharged home from the ED. The mean ISS was 11.2 ± 0.5 while only 31% had an ISS ≥15. There were 97 patients (27.9%) with elevated age adjusted shock index, and 101 patients (29.0%) who required time sensitive interventions.

Transforming mass production of cash crops towards higher socio-ecological standards includes challenges, but also novel opportunities to protect ecosystem services and human health and well-being alike.
