In the treatment of multiple disc herniations, the decision of whether to include the presumed asymptomatic lumbar disc herniation (asLDH) at adjacent segments remains uncertain. On the one hand, the untouched asLDH might soon become symptomatic and require treatment. On the other hand, additional surgery involving more segments will introduce greater risk, complications, and cost.

To investigate the prognosis of untreated asLDH after open fusion or percutaneous endoscopic lumbar discectomy (PELD) on symptomatic lumbar disc herniation (LDHs) in patients.

This is a retrospective cohort study.

A total of 371 patients with multiple disc herniations who underwent open discectomy and fusion or PELD only for symptomatic levels from January 2012 to July 2018 were included.

The primary outcome of interest was the development of symptomatic LDH at the previous asLDH of both groups that required reoperation. A second analysis was performed to compare the reoperation rate due to deterioration of asLDH among dif herniation. When confronting an asLDH graded as G2, a high possibility of reoperation should be clearly discussed with the patient, regardless of open fusion or PELD techniques. Considering that fusion and minimally invasive nonfusion techniques did not yield significantly different overall reoperation rates, ongoing degeneration seemed to have a greater contribution in terms of the deterioration of asLDH.

Resuscitative thoracotomy (RT) is life-saving in select patients and can be accomplished through a left anterolateral (AT) or clamshell thoracotomy (CT). CT may provide additional exposure, facilitating certain operative procedures, but the added blood and heat loss and time to perform it may increase complications. No prospective multicenter comparison of techniques has yet been reported.

The observational AAST Aortic Occlusion for Resuscitation in Trauma and Acute care surgery (AORTA) registry was used to compare AT and CT in RT.

AORTA recorded 1,218 RTs at 46 trauma centers from June 2014 to January 2020. Overall survival after RT was 6.0% (AT 6.6%; [59 of 900]; CT 4.2% [13 of 296], p= 0.132). Among all RTs, 11.1% (142 of 1,278) surviving at least 24 hours were used tocompare AT (112) and CT (30). There was no difference between the 2 groups withregard to age, sex, Injury Severity Score, or mechanism of injury (Table1). CT was significantly more likely to be used in patients needing resection of the lung or cardiac repair. learn more CT was not associated with increased local thoracic/systemic complications, higher transfusion requirement, or greater ventilator, ICU, or hospital days compared with AT.

Clamshell thoracotomy facilitates thoracic life-saving procedures withoutincreased systemic or thoracic complications compared with AT in patients undergoing RT.

C. neoformans species complex is classified into serotype A, serotype D, and AD hybrids, which are currently considered different subspecies. Different serotype strains display varied phenotypes, virulence, and gene regulation. Genetic investigation of important pathways is often performed in both serotype A and D reference strains in order to identify diversification or conservation of the interrogated signaling network. Many genetic tools have been developed for C. neoformans serotype A reference strain H99, including the gene free "safe haven" (SH) regions for DNA integration identified based on genomic features. However, no such a genomic safe haven region has been identified in serotype D strains. Here, capitalizing on the available genomic, transcriptomic, and chromatin data, we identified an intergenic region named as SH3 for the serotype D reference strains JEC21 and XL280. We also designed a sgRNA and a vector facilitating any alien gene integration into SH3 through a CRISPR-Cas9 system. We found that gene inserted in this region complemented the corresponding gene deletion mutant. Fluorescent reporter gene inserted in SH3 can also be expressed efficiently. Insertion in SH3 itself did not alter the expression of adjacent genes and did not affect the growth or mating of C. neoformans. Thus, SH3 provides a resource for genetic manipulations in serotype D strains and will facilitate comparative analyses of gene functions in this species complex. In addition, the incorporation of the multi-omic data in our selection of the safe haven region could help similar studies in other organisms.Trans-generational disease effects include vertical pathogen transmission but also immune priming to enhance offspring immunity. Accordingly, the survival consequences of maternal virus infection can vary and its molecular consequences during early development are poorly understood. The honey bee queen is long-lived and represents the central hub for vertical virus transmission as the sole reproductive individual in her colony. Even though virus symptoms in queens are mild, viral infection may have severe consequences for the offspring. Thus, transcriptome patterns during early developmental are predicted to respond to maternal virus infection. To test this hypothesis, gene expression patterns were compared among pooled honey bee eggs laid by queens that were either infected with Deformed wing virus (DWV1), Sacbrood virus (SBV2), both viruses (DWV and SBV), or no virus. Whole transcriptome analyses revealed significant expression differences of a few genes, some of which have hitherto no known function. Despite the paucity of single gene effects, functional enrichment analyses revealed numerous biological processes in the embryos to be affected by virus infection. Effects on several regulatory pathways were consistent with maternal responses to virus infection and correlated with responses to DWV and SBV in honey bee larvae and pupae. Overall, effects on egg transcriptome patterns were specific to each virus and the results of dual-infection samples suggested synergistic effects of DWV and SBV. We interpret our results as consequences of maternal infections. Thus, this first study to document and characterize virus-associated changes in the transcriptome of honey bee eggs represents an important contribution to understanding trans-generational virus effects, although more in-depth studies are needed to understand the detailed mechanisms of how viruses affect honey bee embryos.
