Authors: Othman Sammy , Christopher Adrienne , Patel Viren , Jia Hanna , Mellia Joseph A. , Kovach Stephen J. , Fischer John P. 
Published: March 2022

Background:
Abdominal wall reconstruction persists as a challenging surgical issue with a multitude of management strategies available. The aim of this study was to examine the efficacy of resorbable synthetic mesh onlay plane against biologic mesh in the intraperitoneal plane.

Methods:
A single-center, two-surgeon, 5-year retrospective review (2014 to 2019) was performed examining subjects who underwent abdominal wall reconstruction in the onlay plane with resorbable synthetic mesh or in the intraperitoneal plane with biologic mesh. A matched paired analysis was conducted. Data examining demographic characteristics, intraoperative variables, postoperative outcomes, and costs were analyzed.

Results:
Eighty-eight subjects (44 per group) were identified (median follow-up, 24.5 months). The mean age was 57.7 years, with a mean body mass index of 30.4 kg/m2. The average defect size was 292 ± 237 cm2, with most wounds being clean-contaminated (48.9 percent) and 55 percent having failed prior repair. Resorbable synthetic mesh onlay subjects were significantly less likely (4.5 percent) to experience recurrence compared to biologic intraperitoneal mesh subjects (22.7 percent; p < 0.026). In addition, mesh onlay suffered fewer postoperative surgical-site occurrences (18.2 percent versus 40.9 percent; p < 0.019) and required fewer procedural interventions (11.4 percent versus 36.4 percent; p < 0.011), and was also associated with significantly lower total costs ($16,658 ± $14,930) compared to biologic intraperitoneal mesh ($27,645 ± $16,864; p < 0.001).

Conclusions:
Abdominal wall reconstruction remains an evolving field, with various techniques available for treatment. When faced with hernia repair, resorbable synthetic mesh in the onlay plane may be preferable to biologic mesh placed in the intraperitoneal plane because of lower long-term recurrence rates, surgical-site complications, and costs.

Adjunctive Nonpharmacologic Interventions for the Management of Burn Pain: A Systematic Review
Authors: Gasteratos Konstantinos , Papakonstantinou Menelaos , Man Angela , Babatsikos Emmanouil , Tamalonis Albina , Goverman Jeremy 
Published: March 2022

Background:
The conventional way of treating burn victims with mainstream pain control modalities is costly and has many negative side effects. In this study, the authors aim to present the findings from the major clinical trials on three nonpharmacologic interventions—hypnosis, virtual/augmented reality, and yoga—as supplements to conventional pain regimens for burn management.

Methods:
A computerized literature search was conducted of the PubMed and ClinicalTrials.gov databases in April of 2020. The online screening process was performed by two independent reviewers with the Covidence tool. The protocol was reported using the Preferred Reporting Items for Systematic Review and Meta-Analyses, and it was registered at the International Prospective Register of Systematic Reviews of the National Institute for Health Research.

Results:
The search yielded 254 articles from 1955 to 2020. Fifty-eight studies met the authors’ inclusion criteria. Yoga reduced cognitive and somatic anxiety in burn survivors, and improved body image. Virtual reality is effective in pain reduction in both the pediatric and the adult burn population, and in faster burn wound reepithelialization. Hypnosis has similar results regarding reducing pain quality and anxiety in burn patients undergoing burn wound care and dressing changes but was not found to significantly accelerate the healing process.

Conclusions:
Nonpharmacologic interventions are not a substitute for conventional analgesics; however, they could help patients have better control over their pain, greater self-esteem, and less postburn traumatic experiences. Burn care centers should consider nonpharmacologic interventions to improve patient satisfaction and their participation in the treatment and rehabilitation process.
Impact of Single Eyelid on Superior Visual Field
Authors: Kitazawa Takeshi , Yuzuriha Shunsuke 
Published: March 2022

Abstract
A puffy eyelid without a crease, also known as single eyelid, is a common characteristic in East Asians. Existence of a lid crease is generally considered an aesthetic concern for both patients and surgeons, and postoperative evaluations have mainly focused on the appearance of the eye. The aim of this study was to clarify the functionality of the superior visual field (SVF) with single eyelid.
This prospective cohort study compared edge of the upper eyelid to central corneal light reflex distance (edge reflex distance [ERD]) preoperatively and postoperatively and examined the SVF, as measured by Goldmann perimetry, in single-eyelid patients who underwent blepharoplasty.
Twenty patients (40 eyelids) with a median age of 21 years were examined. The median preoperative and postoperative ERDs were 1.45 and 3.4 mm, respectively. The median areas of the SVF preoperatively and postoperatively were 34,443 and 50,796 degrees2, respectively. Although a positive correlation existed between preoperative ERD and SVF, no correlation was observed between postoperative ERD and SVF.
The SVF of the single eyelid is narrower than that of the double eyelid, even under circumstances of equivalent palpebral fissure height. The single eyelid commonly found in East Asian populations is associated with both cosmetic and functional issues.

Summary Statement
We present a new simulation-based challenge (Sim’Cup) concept, created in response to the COVID-19 pandemic. It took place in 2020, during the European Society of Emergency Medicine and the Societé Française de Médecine d’Urgence (SFMU) conferences. Usually, during the conferences, a Sim’Cup is held with onsite participants who are involved in a consecutive series of face-to-face simulations organized in 2 qualifying rounds, followed by a final round. When congresses were transformed into online events, the Sim’Cup had to evolve into a virtual format as well. We developed the e-Sim’Cup concept as follows: participants staying safely at home, piloting the trainers, as if they were their own avatar, in a simulation room with a full-scale high-fidelity manikin (Gaumard, Laerdal) using real-time scenarios. Participants gave instructions to the avatars through a smartphone and via a website. Each team participated in 2 scenarios. At the end of each scenario, teams had to undergo a self-debriefing, followed by a short debriefing with the organizers. Twenty-seven participants divided into 9 teams participated in 1 of the 2 e-Sim’Cup events.
We evaluated the impact of this approach using the Educational Practices Questionnaire, and we also analyzed the participants’ perception of their satisfaction and their feelings of improvement with this virtual format. Moreover, we conducted qualitative analyses of the self-debriefings. Thirteen participants filled out the questionnaire, giving a combined high Educational Practices Questionnaire score [72 (66.5–77) of 80], which reflects the presence of educational best practices during the e-Sim’Cups. They appreciated the adjusted Sim’Cup format and believed that they were able to improve their communication, clinical skills, and self-confidence. The qualitative analysis suggested that the approach was perceived as immersive by the 27 participants, with some challenges due to technical problems but an overall feeling of improvement regarding their crisis resource management skills. The hybrid remote simulation concept satisfied the participants who believed that it improved important skills in emergency medicine. The increasing number of remote activities and conferences lead us to believe that our e-Sim’Cup concept can be easily reproducible in any simulation center, as it requires only the application of the educational concept and either the use of the website or the use of some widely available technical devices.

BACKGROUND
Balanced blood component administration during massive transfusion is standard of care. Most literature focuses on the impact of red blood cell (RBC)/fresh frozen plasma (FFP) ratio, while the value of balanced RBC:platelet (PLT) administration is less established. The aim of this study was to evaluate and quantify the independent impact of RBC:PLT on 24-hour mortality in trauma patients receiving massive transfusion.

METHODS
Using the 2013 to 2018 American College of Surgeons Trauma Quality Improvement Program database, adult patients who received massive transfusion (≥10 U of RBC/24 hours) and ≥1 U of RBC, FFP, and PLT within 4 hours of arrival were retrospectively included. To mitigate survival bias, only patients with consistent RBC:PLT and RBC:FFP ratios between 4 and 24 hours were analyzed. Balanced FFP or PLT transfusions were defined as having RBC:PLT and RBC:FFP of ≤2, respectively. Multivariable logistic regression was used to compare the independent relationship between RBC:FFP, RBC:PLT, balanced transfusion, and 24-hour mortality.

RESULTS
A total of 9,215 massive transfusion patients were included. The number of patients who received transfusion with RBC:PLT >2 (1,942 [21.1%]) was significantly higher than those with RBC:FFP >2 (1,160 [12.6%]) (p < 0.001). Compared with an RBC:PLT ratio of 1:1, a gradual and consistent risk increase was observed for 24-hour mortality as the RBC:PLT ratio increased (p < 0.001). Patients with both FFP and PLT balanced transfusion had the lowest adjusted risk for 24-hour mortality. Mortality increased as resuscitation became more unbalanced, with higher odds of death for unbalanced PLT (odds ratio, 2.48 [2.18–2.83]) than unbalanced FFP (odds ratio, 1.66 [1.37–1.98]), while patients who received both FFP and PLT unbalanced transfusion had the highest risk of 24-hour mortality (odds ratio, 3.41 [2.74–4.24]).

CONCLUSION
Trauma patients receiving massive transfusion significantly more often have unbalanced PLT rather than unbalanced FFP transfusion. The impact of unbalanced PLT transfusion on 24-hour mortality is independent and potentially more pronounced than unbalanced FFP transfusion, warranting serious system-level efforts for improvement.

Sex determination and sex chromosome evolution in land plants
Authors: Renner Susanne S. , Müller Niels A. 
Published: March 2022

Linnaeus's very first opus, written when he was 22 years old, dealt with the analogy that exists between plants and animals in how they ‘propagate their species’, and a revised version with a plate depicting the union of male and femaleMercurialis annuaplants became a foundational text on the sexuality of plants. The question how systems with separate males and females have evolved in sedentary organisms that appear ancestrally bisexual has fascinated biologists ever since. The phenomenon, termed dioecy, has important consequences for plant reproductive success and is of commercial interest since it affects seed quality and fruit production. This theme issue presents a series of articles that synthesize and challenge the current understanding of how plants achieve dioecy. The articles deal with a broad set of taxa, includingCoccinia,Ginkgo,Mercurialis,Populus,RumexandSilene, as well as overarching topics, such as the field's terminology, analogies with animal sex determination systems, evolutionary pathways to dioecy, dosage compensation, and the longevity of the two sexes. In this introduction, we focus on four topics, each addressed by several articles from different angles and with different conclusions. Our highlighting of unclear or controversial issues may help future studies to build on the current understanding and to ask new questions that will expand our knowledge of plant sexual systems.This article is part of the theme issue ‘Sex determination and sex chromosome evolution in land plants’.
Some sexual consequences of being a plant
Authors: Cronk Quentin 
Published: March 2022

Plants have characteristic features that affect the expression of sexual function, notably the existence of a haploid organism in the life cycle, and in their development, which is modular, iterative and environmentally reactive. For instance, primary selection (the first filtering of the products of meiosis) is via gametes in diplontic animals, but via gametophyte organisms in plants. Intragametophytic selfing produces double haploid sporophytes which is in effect a form of clonal reproduction mediated by sexual mechanisms. In homosporous plants, the diploid sporophyte is sexless, sex being only expressed in the haploid gametophyte. However, in seed plants, the timing and location of gamete production is determined by the sporophyte, which therefore has a sexual role, and in dioecious plants has genetic sex, while the seed plant gametophyte has lost genetic sex. This evolutionary transition is one that E.J.H. Corner called ‘the transference of sexuality’. The iterative development characteristic of plants can lead to a wide variety of patterns in the distribution of sexual function, and in dioecious plants poor canalization of reproductive development can lead to intrasexual mating and the production of YY supermales or WW superfemales. Finally, plant modes of asexual reproduction (agamospermy/apogamy) are also distinctive by subverting gametophytic processes.

The contributions of Nettie Stevens to the field of sex chromosome biology
Authors: Carey Sarah B. , Aközbek Laramie , Harkess Alex 
Published: March 2022

The early 1900s delivered many foundational discoveries in genetics, including re-discovery of Mendel's research and the chromosomal theory of inheritance. Following these insights, many focused their research on whether the development of separate sexes had a chromosomal basis or if instead it was caused by environmental factors. It is Dr Nettie M. Stevens'Studies in spermatogenesis(1905) that provided the unequivocal evidence that the inheritance of the Y chromosome initiated male development in mealworms. This result established that sex is indeed a Mendelian trait with a genetic basis and that the sex chromosomes play a critical role. In Part II ofStudies in spermatogenesis(1906), an XY pair was identified in dozens of additional species, further validating the function of sex chromosomes. Since this formative work, a wealth of studies in animals and plants have examined the genetic basis of sex. The goal of this review is to shine a light again on Stevens’Studies in spermatogenesisand the lasting impact of this work. We additionally focus on key findings in plant systems over the last century and open questions that are best answered, as in Stevens' work, by synthesizing across many systems.This article is part of the theme issue ‘Sex determination and sex chromosome evolution in land plants’.
Dosage compensation evolution in plants: theories, controversies and mechanisms
Authors: Muyle Aline , Marais Gabriel A. B. , Bačovský Václav , Hobza Roman , Lenormand Thomas 
Published: March 2022

In a minority of flowering plants, separate sexes are genetically determined by sex chromosomes. The Y chromosome has a non-recombining region that degenerates, causing a reduced expression of Y genes. In some species, the lower Y expression is accompanied by dosage compensation (DC), a mechanism that re-equalizes male and female expression and/or brings XY male expression back to its ancestral level. Here, we review work on DC in plants, which started as early as the late 1960s with cytological approaches. The use of transcriptomics fired a controversy as to whether DC existed in plants. Further work revealed that various plants exhibit partial DC, including a few species with young and homomorphic sex chromosomes. We are starting to understand the mechanisms responsible for DC in some plants, but in most species, we lack the data to differentiate between global and gene-by-gene DC. Also, it is unknown why some species evolve many dosage compensated genes while others do not. Finally, the forces that drive DC evolution remain mysterious, both in plants and animals. We review the multiple evolutionary theories that have been proposed to explain DC patterns in eukaryotes with XY or ZW sex chromosomes.

Published: March 2022

Microscopically dimorphic sex chromosomes in plants are rare, reducing our ability to study them. One difficulty has been the paucity of cultivatable species pairs for cytogenetic, genomic and experimental work. Here, we study the newly recognized sistersCoccinia grandisandCoccinia schimperi, both with large Y chromosomes as we here show forCo. schimperi. We built genetic maps for male and femaleCo. grandisusing a full-sibling family, inferred gene sex-linkage, and, withCo. schimperitranscriptome data, tested whether X- and Y-alleles group by species or by sex. Most sex-linked genes for which we could include outgroups grouped the X- and Y-alleles by species, but some 10% instead grouped the two species' X-alleles. There was no relationship between XY synonymous-site divergences in these genes and gene position on the non-recombining part of the X, suggesting recombination arrest shortly before or after species divergence, here dated to about 3.6 Ma.Coccinia grandisandCo. schimperiare the species pair with the most heteromorphic sex chromosomes in vascular plants (the condition in their sister remains unknown), and future work could use them to study mechanisms of Y chromosome enlargement and parallel degeneration, or to test Haldane's rule about lower hybrid fitness in the heterogametic sex.This article is part of the theme issue ‘Sex determination and sex chromosome evolution in land plants’.
The distribution of sexual function in the flowering plant: from monoecy to dioecy
Authors: Cronk Quentin 
Published: March 2022

In flowering plants, male and female functions are usually closely associated in the same flowers, as predicted by resource allocation theory. However, the benefits of outbreeding can lead to unisexual flowers and the physiological control of their distribution across the plant (monoecy). Monoecy is thought to be a major route to dioecy (separation of sexual function of different individuals). The developmental and functional problems associated with unisexual flowers may thus be solved at the level of the evolution of monoecy. Consequently, the evolution of dioecy from monoecy requires mutations in only a single gene. Here various scenarios (conceptual models) are presented for the evolution of monoecy and dioecy, including scenarios consistent with known cases of single-gene control of dioecy, such as inPopulus, and the artificial breeding of dioecy from monoecy experimentally achieved inZeaandCucumis. Attention is also drawn here to the phenomenon of pleogamy, the minor or occasional occurrence of additional sex morphs within a species, which may provide important information about the genetic and developmental control of various sexual systems.This article is part of the theme issue ‘Sex determination and sex chromosome evolution in land plants’.
Longitudinal brain age prediction and cognitive function after stroke

Published: March 2022

AbstractBackgroundAdvanced age and poor brain health have been associated with higher risk for more severe clinical and cognitive outcomes following stroke, but more accurate models for clinical prediction are needed. Machine learning based on brain scans can be used to estimate brain age of individual patients, and the corresponding difference from chronological age, the brain age gap (BAG) has been investigated in a range of clinical conditions. Yet, the predictive value for post stroke NCD has not been established. To this end, using longitudinal data we aimed to investigate the association between BAG and post-stroke neurocognitive disorder (NCD) over time.Methods269 stroke survivors (55.4% women, mean (SD) age = 71 (11) years) were included from the Norwegian Cognitive Impairment After Stroke (Nor-COAST) study. MRI and clinical data were collected shortly after the acute stroke (neuropsychological data first after 3 months) and at 18- and 36 months follow-up. The brain age model was trained in an independent sample using established protocols based on machine learning and brain structural features from Freesurfer and applied to the current dataset. We used linear mixed effects (LME) models and survival analysis to assess the associations between cognitive status and longitudinal brain age.ResultsLMEs revealed a main effect of BAG on post stroke NCD across time, confirming our main hypothesis that a younger appearing brain may protect against post stroke NCD. For patients with no NCD at baseline, survival analysis suggested that higher baseline BAG was associated with higher risk of post stroke NCD at 18 and 36 months.ConclusionA younger appearing brain is associated with lower risk of post stroke NCD up to 36 months after a stroke, even among those showing no evidence of impairments 3 months after hospital admission. Brain age prediction based on brain scans provides a reliable assessment of brain structure and is sensitive to post stroke NCD with predictive value for cognitive decline among patients with no impairment at the initial assessment.
