SYMMETRIC MONOIDALG-CATEGORIES AND THEIR STRICTIFICATION
Authors: Guillou Bertrand J , May J Peter , Merling Mona , Osorno Angélica M 
Published: December 2019

AbstractWe give an operadic definition of a genuine symmetric monoidal $G$-category, and we prove that its classifying space is a genuine $E_\infty $$G$-space. We do this by developing some very general categorical coherence theory. We combine results of Corner and Gurski, Power and Lack to develop a strictification theory for pseudoalgebras over operads and monads. It specializes to strictify genuine symmetric monoidal $G$-categories to genuine permutative $G$-categories. All of our work takes place in a general internal categorical framework that has many quite different specializations. When $G$ is a finite group, the theory here combines with previous work to generalize equivariant infinite loop space theory from strict space level input to considerably more general category level input. It takes genuine symmetric monoidal $G$-categories as input to an equivariant infinite loop space machine that gives genuine $\Omega $-$G$-spectra as output.
IgG4-related disease: a clinical perspective
Authors: Maritati Federica , Peyronel Francesco , Vaglio Augusto 
Published: December 2019

AbstractIgG4-related disease (IgG4-RD) is a recently recognized fibro-inflammatory disorder that can affect almost any organ. Common presentations include major salivary and lacrimal gland enlargement, orbital disease, autoimmune pancreatitis, retroperitoneal fibrosis and tubulointerstitial nephritis. The main histopathological features are a dense, polyclonal, lymphoplasmacytic infiltrate rich in IgG4+ plasma cells, storiform fibrosis and obliterative phlebitis. The precise pathogenic mechanisms of IgG4-RD are still unclear. CD4+ T and B cells, including IgG4-expressing plasmablasts, constitute the major inflammatory cell populations and are believed to cause organ damage and tissue fibrosis. The diagnosis of the disease may be challenging and should be based on specific histopathological findings, typical laboratory and radiological aspects and an appropriate clinical context. The first-line treatment of IgG4-RD is based on glucocorticoids, which are usually efficacious. However, B cell depletion induced by rituximab has also been found to induce remission in steroid-resistant disease or has been used as steroid-sparing agent for relapsing disease. This review provides an update on clinical and therapeutic aspects of IgG4-RD.

Abstract
One-on-one peer coaching/support programs hold promise in promoting healthy outcomes among women at risk for and surviving with breast cancer, with the potential to bridge gaps in “whole person care.” Although popularly cited for their benefits, emerging evidence is mixed and suggests that peer support program impacts may be attenuated by individual- and community-specific factors. We evaluated a national not-for-profit breast cancer organization’s peer support program outcomes (2015–2018) serving women from predominantly Jewish backgrounds to examine program engagement, facilitation, and satisfaction. Of the N = 392 women sampled, 37% utilized the peer support program: the majority were referred by a family member/friend (40%) or had connected with the program online (34%). Logistic regression modeling revealed that mothers (odds ratio [OR] = 1.82; 95% confidence interval [CI] = 1.04 to 3.19), women at increased genetic risk for breast cancer (OR = 2.07; 95% CI = 1.08 to 3.94), and those who connected with the organization through a family member/friend (OR = 1.97; 95% CI = 1.23 to 3.15) were significantly more likely to utilize peer support (all p’s &lt; .05). Satisfaction with peer support was high and reliably measured (M = 42.8 out of possible 50; α = .95). These findings emphasize opportunities for peer support programs to serve a range of needs among breast cancer previvors and survivors and increase health care’s organizational capacity to reach and impact this community through trusted and well-trained lay coaches.
Intimidation and Sexual Harassment during Plastic Surgery Training in the United States
Authors: D’Agostino Johanna P. , Vakharia Kavita T. , Bawa Sheina , Sljivic Sanja , Natoli Noel 
Published: December 2019

Background:
Attending physicians, peers, other providers, and patients are sources of intellectual growth, but may also be a source of abuse and harassment. Published international studies have found that harassment within residency training is widespread but there is little data regarding plastic surgery training. The authors sought to explore the incidence of harassment experienced by plastic surgery residents currently enrolled in US integrated and independent programs.

Methods:
After an IRB-approved exemption was obtained, an anonymous internet-based survey was distributed via email to all plastic and reconstructive surgery residency programs. The survey was comprised of 23 questions that focused on personal experience or knowledge of other colleagues who had encountered abuse and harassment during their training. Responses were collected during a 60-day period. The response rate was 16%.

Results:
A total of 173 individuals completed the survey. Regarding harassment experienced by the respondents, 39.2% reported verbal abuse, 19.9% experienced sexual harassment, and 3.6% reported being physically abused during their training. Of those individuals who were sexually harassed, 72.7% were females. In many of the cases (64.5%), the instigator was a supervising physician. Most respondents did not feel comfortable reporting the abuse (74.19%).

Conclusions:
Abuse and sexual harassment rates among active plastic and reconstructive surgery residents in the United States are high and attention should be brought to this important issue. Further studies should be conducted to assess the extent of abuse so that it can lead to implementation of programs that provide accountability, improved support, counseling strategies, and foster appropriate professional development.
Single-photon emission computed tomography/computed tomography arthrography of wrist, ankle, and knee joints
Authors: Bhure Ujwal , Roos Justus E. , Perez-Lago Maria del Sol , Strobel Klaus 
Published: December 2019

Objective
To evaluate the additional value of single-photon emission computed tomography/computed tomography arthrography compared with single-photon emission computed tomography/computed tomography alone in wrist, ankle, and knee joints.

Materials and methods
Retrospective evaluation of 68 patients including 74 joints (48 wrists, 13 upper ankle (talocrural joint), and 13 knee joints) was performed. Activity in single-photon emission computed tomography/computed tomography images was graded using a four-point scale: 0 no uptake, one low uptake, two moderate uptake, and three high uptake. Arthrography images were evaluated for the presence of cartilage/ligament/meniscal lesions, and loose bodies.

Results
Fifty-six joints (76%) showed increased activity in late planar and 58 (78%) in single-photon emission computed tomography/computed tomography images, the latter graded as follows: grade 1 in 20 (34%), grade 2 in 29 (50%), grade 3 in nine (16%) joints. 16 joints were inactive (grade 0) in single-photon emission computed tomography/computed tomography. In 57 joints (77%), intraarticular contrast unmasked additional pathologies (37 cartilage lesions, 25 ligaments tears, 25 triangular fibrocartilage complex tears, six meniscal lesions, and four loose bodies). There was matching findings between single-photon emission computed tomography and computed tomography arthrography in 57 joints (77%) and mismatching findings in 17 joints (23%). Out of these 17 mismatched joints, eight were metabolically inactive but showed some lesion in computed tomography arthrography, whereas nine metabolically active joints did not show any abnormality in computed tomography arthrography.

Conclusion
The addition of arthrography to single-photon emission computed tomography/computed tomography of wrist, ankle, and knee joints leads to supplementary visibility of lesions of cartilage, ligaments, triangular fibrocartilage complex, meniscus, or loose bodies in 77% of joints. Single-photon emission computed tomography/computed tomography arthrography can serve as promising alternative especially in patients with magnetic resonance imaging contraindications or metallic hardware.
Cancer cachexia: a multifactoral disease that needs a multimodal approach
Authors: Stubbins Renee , Bernicker Eric H. , Quigley Eamonn M.M. 
Published: December 2019

Purpose of review
Cancer cachexia is a complex condition that occurs in approximately 50% of cancer patients and in 80% of those with advanced cancer. It is characterized by lean body mass loss, adipose tissue loss, altered metabolism, increased inflammation, and a decrease in quality of life. Cancer cachexia is a frustrating condition to manage and treatment requires an innovative approach. The purpose of this article is to review the current treatments for cancer cachexia and how they could be used in a multimodal approach.

Recent findings
Cancer cachexia has many causes, but is primarily a result of reduced energy-protein intake and altered metabolism augmented by a proinflammatory state. There is not a formal consensus on diagnosing cancer cachexia, but proactive screening and assessments for malnutrition are an effective first step toward identifying high-risk patients. Treatment of cancer cachexia includes optimizing nutrition care, using appropriate pharmacological agents, preserving lean body mass, and the cooperation of the healthcare team.

Summary
Cancer cachexia is a complex multifactorial condition that can only be successfully managed and treated with a multimodal approach that involves a multidisciplinary team that includes an oncology registered dietitian nutritionist and exercise physiologist that target early detection and management of cancer cachexia.
Hypomethylating agents with venetoclax: have we discovered the holy grail?
Authors: Gutman Jonathan A. , Pollyea Daniel A. 
Published: December 2019

Purpose of review
Since its approval in November 2018, venetoclax with a hypomethylating agent backbone has shown promising efficacy for older, newly diagnosed acute myeloid leukemia (AML) patients who are unfit for standard intensive induction chemotherapy. This regimen is well tolerated, allows for deep and durable responses and may be increasing the prevalence of the disease. Although there is justifiable excitement, it remains to be seen to what extent venetoclax-based regimens, as they are currently administered, will have a long-term impact on the treatment of AML. This review aims to evaluate the strengths of the regimen that deserve enthusiasm as well as its shortcomings, which should be viewed as opportunities for improvement.

Recent findings
The clinical efficacy as well as the novel mechanism of venetoclax with hypomethylating agents will be described here.

Summary
Venetoclax with hypomethylating agents do not represent the holy grail for AML, but this regimen is a promising step in the right direction, and proof of principle that a low-intensity therapy can have a major impact on this disease.

Authors: Jahrreiss Victoria , Veser Julian , Seitz Christian , Özsoy Mehmet 
Published: December 2019

Purpose of review
To investigate the application of artificial intelligence in the management of nephrolithiasis.

Recent findings
Although rising, the number of publications on artificial intelligence for the management of urinary stone disease is still low. Most publications focus on diagnostic tools and prediction of outcomes after clinical interventions. Artificial intelligence can, however, play a major role in development of surgical skills and automated data extraction to support clinical research.

Summary
The combination of artificial intelligence with new technological developments in the field of endourology will create new possibilities in the management of urinary stones. The implication of artificial intelligence can lead to better patient selection, higher success rates, and furthermore improve patient safety.
Whither Research Domain Criteria?
Authors: Dean Charles E. 
Published: December 2019

Abstract
In 2010, the National Institute of Mental Health launched the Research Diagnostic Criteria (RDoC) as a research framework aimed at advancing research into the etiology of mental disorders, the development of clinically actionable biomarkers, and the eventual development of precision medications. The foundation of RDoC in that first phase rested in the assumption that mental disorders are brain disorders that originate in aberrant neural circuitry, and that therapeutic advances could flow from alterations in that circuitry. RDoC proposed a matrix of psychological constructs with seven levels of analysis ranging from the cell to self-report, but with neural circuitry at the center. In 2016, another model was proposed in which neural circuitry became equivalent to other units of analyses. With the advent of a new Director of the NIMH, the emphasis returned to neural circuitry as a priority, along with computational psychiatry. Have these shifts undermined the RDoC project?
Effect of Simulated and Real Spherical and Astigmatism Defocus on Visual Acuity and Image Quality Score
Authors: Vincent Marc , Marin Gildas , Legras Richard 
Published: December 2019

SIGNIFICANCE
Image simulation is a useful and efficient tool to explore the impact of spherical and astigmatic blur on visual acuity (VA) and image gradation. It could help to design new optical corrections more efficiently and rapidly.

PURPOSE
The purpose of this study was to compare the effects of simulated (convolution by an artificial eye) and real spherical and astigmatic defocus on VA and image gradation.

METHODS
Experiments were performed under highly controlled conditions: dynamic correction of the subjects' aberrations at 1 Hz and application of an artificial pupil. In experiment 1, Landolt C VA was measured in various conditions of spherical and astigmatism defocus. The amounts of spherical or positive astigmatic defocus oriented at 45° that gives a Landolt C VA of 0.0, 0.2, and 0.5 logMAR were measured in experiment 2. In experiment 3, the subjects scored the quality of the perceived image (three high-contrast 0.4 logMAR letters) with a five-item continuous grading scale.

RESULTS
Simulated blur was always more detrimental than optical blur. We measured a difference of 0.08 ± 0.03 and 0.11 ± 0.05 logMAR between both conditions, respectively, in presence of spherical and astigmatism defocus. An average ± standard deviation difference of 0.16 ± 0.06 D (i.e., spherical defocus) and 0.24 ± 0.15 D (i.e., astigmatism defocus) was observed between simulated and real optics blur to provide a given VA. The differences of image quality score between both conditions were, respectively, 15.13 ± 9.63 and 13.33 ± 4.83 for spherical and astigmatism defocus. Most of the differences were statistically significant.

CONCLUSIONS
We observed a difference of about 20 and 35% between simulated and real optics blur, respectively, in presence of spherical and astigmatism blur. However, the difference between both methods remains equal to or below the clinically significant difference.
The steering gaits of sperm

Published: December 2019

Sperm are highly specialized cells, which have been subject to substantial evolutionary pressure. Whereas some sperm features are highly conserved, others have undergone major modifications. Some of these variations are driven by adaptation to mating behaviours or fitness at the organismic level. Others represent alternative solutions to the same task. Sperm must find the egg for fertilization. During this task, sperm rely on long slender appendages termed flagella that serve as sensory antennas, propellers and steering rudders. The beat of the flagellum is periodic. The resulting travelling wave generates the necessary thrust for propulsion in the fluid. Recent studies reveal that, for steering, different species rely on different fundamental features of the beat wave. Here, we discuss some examples of unity and diversity across sperm from different species with a particular emphasis on the steering mechanisms.This article is part of the Theo Murphy meeting issue ‘Unity and diversity of cilia in locomotion and transport’.
Multiscale mechanics of mucociliary clearance in the lung
Authors: Nawroth Janna C. , van der Does Anne M. , Ryan (Firth) Amy , Kanso Eva 
Published: December 2019

Mucociliary clearance (MCC) is one of the most important defence mechanisms of the human respiratory system. Its failure is implicated in many chronic and debilitating airway diseases. However, due to the complexity of lung organization, we currently lack full understanding on the relationship between these regional differences in anatomy and biology and MCC functioning. For example, it is unknown whether the regional variability of airway geometry, cell biology and ciliary mechanics play a functional role in MCC. It therefore remains unclear whether the regional preference seen in some airway diseases could originate from local MCC dysfunction. Though great insights have been gained into the genetic basis of cilia ultrastructural defects in airway ciliopathies, the scaling to regional MCC function and subsequent clinical phenotype remains unpredictable. Understanding the multiscale mechanics of MCC would help elucidate genotype–phenotype relationships and enable better diagnostic tools and treatment options. Here, we review the hierarchical and variable organization of ciliated airway epithelium in human lungs and discuss how this organization relates to MCC function. We then discuss the relevancy of these structure–function relationships to current topics in lung disease research. Finally, we examine how state-of-the-art computational approaches can help address existing open questions.

Neuronal coordination of motile cilia in locomotion and feeding
Authors: Marinković Milena , Berger Jürgen , Jékely Gáspár 
Published: December 2019

Efficient ciliary locomotion and transport require the coordination of motile cilia. Short-range coordination of ciliary beats can occur by biophysical mechanisms. Long-range coordination across large or disjointed ciliated fields often requires nervous system control and innervation of ciliated cells by ciliomotor neurons. The neuronal control of cilia is best understood in invertebrate ciliated microswimmers, but similar mechanisms may operate in the vertebrate body. Here, we review how the study of aquatic invertebrates contributed to our understanding of the neuronal control of cilia. We summarize the anatomy of ciliomotor systems and the physiological mechanisms that can alter ciliary activity. We also discuss the most well-characterized ciliomotor system, that of the larval annelidPlatynereis. Here, pacemaker neurons drive the rhythmic activation of cholinergic and serotonergic ciliomotor neurons to induce ciliary arrests and beating. ThePlatynereisciliomotor neurons form a distinct part of the larval nervous system. Similar ciliomotor systems likely operate in other ciliated larvae, such as mollusc veligers. We discuss the possible ancestry and conservation of ciliomotor circuits and highlight how comparative experimental approaches could contribute to a better understanding of the evolution and function of ciliary systems.This article is part of the Theo Murphy meeting issue ‘Unity and diversity of cilia in locomotion and transport’.
Multiple merger genealogies in outbreaks ofMycobacterium tuberculosis
Authors: Menardo F. , Gagneux S. , Freund F. 
Published: December 2019

AbstractThe Kingman coalescent and its developments are often considered among the most important advances in population genetics of the last decades. Demographic inference based on coalescent theory has been used to reconstruct the population dynamics and evolutionary history of several species, includingMycobacterium tuberculosis(MTB), an important human pathogen causing tuberculosis. One key assumption of the Kingman coalescent is that the number of descendants of different individuals does not vary strongly, and violating this assumption could lead to severe biases caused by model misspecification. Individual lineages of MTB are expected to vary strongly in reproductive success because 1) MTB is potentially under constant selection due to the pressure of the host immune system and of antibiotic treatment, 2) MTB undergoes repeated population bottlenecks when it transmits from one host to the next, and 3) some hosts show much higher transmission rates compared to the average (“super-spreaders”).Here we used an Approximate Bayesian Computation approach to test whether multiple merger coalescents (MMC), a class of models that allow for large variation in reproductive success among lineages, are more appropriate models to study MTB populations. We considered eleven publicly available whole genome sequence data sets sampled from local MTB populations and outbreaks, and found that MMC had a better fit compared to the Kingman coalescent for ten of the eleven data sets. These results indicate that the null model for analyzing MTB outbreaks should be reassessed, and that past findings based on the Kingman coalescent need to be revisited.

These findings remained consistent in sensitivity analyses that were robust to the presence of pleiotropic variants. Results from analyses considering individual-participant data were similar, even after adjustment for clinical covariates, including left atrial size.ConclusionGenetically predicted height is a positive causal risk factor for AF. This finding raises the possibility of investigating height/growth-related pathways as a means for gaining novel mechanistic insights to atrial fibrillation, as well as incorporating height into population screening strategies for atrial fibrillation.
