Background: Portable automated infrared pupillometry is becoming increasingly popular. To generate an objective reference base, the Neurological Pupil index (NPi) which combines different values of the pupillary light reflex is being introduced into clinical practice. In this explorative study, we examined different aspects of the NPi in relation to clinical severity and outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). Materials and Methods: Patients with serial assessment of the NPi (NeurOptics pupillometer NPi-200, Irvine, CA) starting no later than day 2 after aSAH onset were included in the study. Relative numbers of pathologic NPi's, absolute NPi values, and their variances were compared according to aSAH clinical severity grade, functional outcome, and case fatality. The correlation between NPi and intracranial pressure, and NPi periodicity, were also examined. Results: In total, 18 patients with 4456 NPi values were eligible for inclusion in the analysis. The general trend of the NPi over time reflected the course of the neurological illness. Mean NPi tended to be lower in patients with clinically severe compared with nonsevere aSAH (3.75±0.40 vs. 4.56±0.06; P=0.171), and in patients with unfavorable compared with favorable outcomes (3.64±0.48 vs. 4.50±0.08; P=0.198). The mean variance of the NPi was higher in patients with severe compared with nonsevere aSAH (0.49±0.17 vs. 0.06±0.02; P=0.025). Pathologic NPi values were recorded more frequently in patients with severe compared with nonsevere aSAH (16.3%±8.8% vs. 0.0%±0.0%; P=0.002), and in those with unfavorable compared with favorable outcomes (19.2%±10.6% vs. 0.7%±0.6%; P=0.017). NPi was inversely correlated with intracranial pressure (Spearman r=−0.551, P

Dexamethasone Is Superior to Dexmedetomidine as a Perineural Adjunct for Supraclavicular Brachial Plexus Block: Systematic Review and Indirect Meta-analysis
BACKGROUND: Both dexamethasone and dexmedetomidine are effective peripheral nerve block (PNB) perineural adjuncts that prolong block duration. However, each is associated with side effects. With paucity of head-to-head comparisons of these adjuncts, the question of the best adjunct to mix with local anesthetics (LA) for PNB is unanswered. This meta-analysis aims to inform current practice and future research by identifying the superior adjunct by comparing dexamethasone and dexmedetomidine. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, trials comparing the combination of perineural dexamethasone or dexmedetomidine with LA to LA alone for PNB were sought. The Cochrane Risk of Bias Tool was used to assess the methodological quality of trials, and indirect or network meta-analyses using random-effects modeling were planned. We designated duration of analgesia as a primary outcome. Secondary outcomes included sensory and motor block durations, sensory and motor block onset times, and the risks of hypotension, sedation, and neurological symptoms. RESULTS: Fifty trials were identified, including only 1 direct comparison, precluding a network meta-analysis. Indirect meta-analysis of 49 trials (3019 patients) was performed. Compared to dexmedetomidine, dexamethasone prolonged the duration of analgesia by a mean difference (95% confidence interval [CI]) of 148 minutes (37–259 minutes) (P = .003), without prolonging sensory/motor blockade. Dexmedetomidine increased rates of hypotension (risk ratio [95% CI], 6.3 [1.5–27.5]; P = .01) and sedation (risk ratio [95% CI], 15.8 [3.9–64.6]; P = .0001). Overall risk of bias was moderate, and publication bias was noted, resulting in downgrading evidence strength. CONCLUSIONS: There is low-quality evidence that both adjuncts similarly prolong sensory/motor blockade. However, dexamethasone may be a superior adjunct; it improves the duration of analgesia by a statistically significant increase, albeit clinically modest, equivalent to 2.5 hours more than dexmedetomidine, without the risks of hypotension or sedation. Future direct comparisons are encouraged. Accepted for publication September 10, 2018.

Propofol Regulates Neural Stem Cell Proliferation and Differentiation via Calmodulin-Dependent Protein Kinase II/AMPK/ATF5 Signaling Axis
BACKGROUND: Propofol can cause degeneration of developing brain cells and subsequent long-term learning or memory impairment. However, at the early stage of embryonic development, the molecular mechanism of propofol-induced inhibition in neural stem cells (NSCs) neurogenesis is still unclear. The aim of this study was to determine the role of propofol in NSCs neurogenesis and, more importantly, to explore the underlying mechanism. METHODS: First, a single intraperitoneal injection of propofol was performed in pregnant mice, and 6 hours after administration of propofol, the hippocampus RNA and the protein of the embryos' brains was extracted to analyze the expression of neuron-specific markers. Second, the primary NSCs were isolated from the hippocampus of mouse embryonic brain and then treated with propofol for cell viability, immunostaining, and transwell assays; more importantly, we performed RNA sequencing (RNA-seq) and q-reverse transcription polymerase chain reaction assays to identify genes regulated by propofol; the Western blot, small interfering RNA (SiRNA), and luciferase reporter assays were used to study the effects of propofol on calmodulin-dependent protein kinase (CaMk) II/5' adenosine monophosphate-activated protein kinase (AMPK)/activating transcription factor 5 (ATF5) signaling pathway. RESULTS: Our results indicated that propofol treatment could inhibit the proliferation, migration, and differentiation of NSCs. The results of RNA-seq assays showed that propofol treatment resulted in downregulation of a group of Ca2+-dependent genes. The following mechanism studies showed that propofol regulates the proliferation, differentiation, and migration of NSCs through the CaMkII/phosphorylation of serine at amino acid position 485 (pS485)/AMPK/ATF5 signaling pathway. CONCLUSIONS: The results from study demonstrated that propofol inhibits the proliferation, differentiation, and migration of NSCs, and these effects are partially mediated by CaMkII/pS485/AMPK/ATF5 signaling pathway.

Best Practices for Postoperative Brain Health: Recommendations From the Fifth International Perioperative Neurotoxicity Working Group
As part of the American Society of Anesthesiology Brain Health Initiative goal of improving perioperative brain health for older patients, over 30 experts met at the fifth International Perioperative Neurotoxicity Workshop in San Francisco, CA, in May 2016, to discuss best practices for optimizing perioperative brain health in older adults (ie, >65 years of age). The objective of this workshop was to discuss and develop consensus solutions to improve patient management and outcomes and to discuss what older adults should be told (and by whom) about postoperative brain health risks. Thus, the workshop was provider and patient oriented as well as solution focused rather than etiology focused. For those areas in which we determined that there were limited evidence-based recommendations, we identified knowledge gaps and the types of scientific knowledge and investigations needed to direct future best practice. Because concerns about perioperative neurocognitive injury in pediatric patients are already being addressed by the SmartTots initiative, our workshop discussion (and thus this article) focuses specifically on perioperative cognition in older adults. The 2 main perioperative cognitive disorders that have been studied to date are postoperative delirium and cognitive dysfunction. Postoperative delirium is a syndrome of fluctuating changes in attention and level of consciousness that occurs in 20%–40% of patients >60 years of age after major surgery and inpatient hospitalization. Many older surgical patients also develop postoperative cognitive deficits that typically last for weeks to months, thus referred to as postoperative cognitive dysfunction. Because of the heterogeneity of different tools and thresholds used to assess and define these disorders at varying points in time after anesthesia and surgery, a recent article has proposed a new recommended nomenclature for these perioperative neurocognitive disorders. Our discussion about this topic was organized around 4 key issues: preprocedure consent, preoperative cognitive assessment, intraoperative management, and postoperative follow-up. These 4 issues also form the structure of this document. Multiple viewpoints were presented by participants and discussed at this in-person meeting, and the overall group consensus from these discussions was then drafted by a smaller writing group (the 6 primary authors of this article) into this manuscript. Of course, further studies have appeared since the workshop, which the writing group has incorporated where appropriate. All participants from this in-person meeting then had the opportunity to review, edit, and approve this final manuscript; 1 participant did not approve the final manuscript and asked for his/her name to be removed.

Effect of Apneic Oxygenation on Tracheal Oxygen Levels, Tracheal Pressure, and Carbon Dioxide Accumulation: A Randomized, Controlled Trial of Buccal Oxygen Administration
BACKGROUND: Apneic oxygenation via the oral route using a buccal device extends the safe apnea time in most but not all obese patients. Apneic oxygenation techniques are most effective when tracheal oxygen concentrations are maintained >90%. It remains unclear whether buccal oxygen administration consistently achieves this goal and whether significant risks of hypercarbia or barotrauma exist. METHODS: We conducted a randomized trial of buccal or sham oxygenation in healthy, nonobese patients (n = 20), using prolonged laryngoscopy to maintain apnea with a patent airway until arterial oxygen saturation (SpO2) dropped 90% during apnea. RESULTS: Buccal patients were more likely to achieve the primary outcome (P 94%; 750 seconds (750–750 seconds) vs 447 seconds (405–525 seconds); P

Preclinical Evaluation of Ropivacaine in 2 Liposomal Modified Systems
BACKGROUND: Our research group has recently developed liposomes with ionic gradient and in a combined manner as donor and acceptor vesicles containing ropivacaine (RVC; at 2% or 0.75%). Looking for applications of such novel formulations for postoperative pain control, we evaluated the duration of anesthesia, pharmacokinetics, and tissue reaction evoked by these new RVC formulations. METHODS: The formulations used in this study were large multivesicular vesicle (LMVV) containing sodium acetate buffer at pH 5.5 or in a combined manner with LMVV as donor and large unilamellar vesicles (LUVs) as acceptor vesicles with an external pH of 7.4. Wistar rats were divided into 6 groups (n = 6) and received sciatic nerve block (0.4 mL) with 6 formulations of RVC (LMVVRVC0.75%, LMVV/LUVRVC0.75%, LMVVRVC2%, LMVV/LUVRVC2%, RVC 0.75%, and RVC 2%). To verify the anesthetic effect, the animals were submitted to the pain pressure test and the motor block was also monitored. Histopathology of the tissues surrounding the sciatic nerve region was also assessed 2 and 7 days after treatment. Rats (n = 6) were submitted to a hind paw incision, and mechanical hypersensitivity was measured via the withdrawal response using von Frey filaments after injection of the 6 formulations. Finally, New Zealand white rabbits (n = 6) received sciatic nerve block (3 mL) with 1 of the 6 formulations of RVC. Blood samples were collected predose (0 minutes) and at 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 420, 480, and 540 minutes after injection. RVC plasma levels were determined using a triple-stage quadrupole mass spectrometer. RESULTS: Duration and intensity of the sensory block were longer with all liposomal formulations, when compared to the plain RVC solution (P

Overaugmentation to compensate for postextraction ridge atrophy using a putty-type porcine bone substitute material with recombinant bone morphogenetic protein-2: 4 weeks of healing in a canine model
Abstract
Objectives
The aims of the present study were (i) to determine the short-term effects of putty-type porcine bone substitute material (PB) with recombinant bone morphogenetic protein-2 (rhBMP-2) for alveolar ridge preservation (ARP) and (ii) evaluate the early healing of labial overaugmentation.
Materials and methods
Two groups were randomly assigned to the extraction sockets in mandibular incisors of eight dogs: labial overaugmentation with (i) PB (control) or (ii) rhBMP-2-loaded PB (BMP). Microcomputed tomography (micro-CT), and histologic and histomorphometric analyses were performed after 4 weeks.
Results
Micro-CT revealed that some of the overaugmented PB was dispersed in both groups. The new bone volume was significantly larger in the BMP group than in the control group (18.4 ± 3.3 vs. 15.5 ± 3.0 mm3, mean ± SD, P < 0.05). Labial bone resorption was generally found histologically. No signs of mineralization were observed in the overaugmented area despite significantly increased ridge width, as compared to the adjacent tooth area. The area of new bone formation was larger in the BMP group than in the control group overall (23.7 ± 18.8 vs. 18.3 ± 21.2 mm2) and in three parts (apical, middle, and coronal), although the difference was statistically significant only in the coronal part (7.7 ± 7.9 vs. 4.6 ± 6.4 mm2, P < 0.05).
Conclusions
The addition of rhBMP-2 enhanced ossification in the coronal part of the extraction socket relative to using PB alone. Overaugmentation increased the ridge dimension with no evidence of ossification in situ at 4 weeks.
Clinical relevance
In early healing following ARP, rhBMP-2 enhances bone formation within the socket, but ossification in the overaugmented area needs to be studied further.

Effect of NaF, AmF, KF gels and NaF toothpaste combined with a saliva substitute on dentin lesions in vitro
Abstract
Objective
The aim of the present in vitro study was to evaluate the remineralizing effects of NaF, AmF, KF gels and NaF toothpaste in combination with a potentially demineralizing saliva substitute (Glandosane; pH = 5.1) being widely used in Germany.
Methods
In each of 120 dentin specimens, three artificial lesions were created. One lesion was covered for analysis of pre-demineralization (ΔZB). Treatments during pH cycling (3 × 1 h demineralization/day [pH = 5.0] and 3 × 3 h Glandosane/day; 12 h 100%humidity) were as follows: no treatment (NT), application (5 min,2×/day) of 12.500 ppm F− [pH = 6.04] (NaF-gel1), 12.500 ppm F− [pH = 7.34] (NaF-gel2), 12.500 ppm F− [pH = 5.82] (AmF-gel), 1450 ppm F− [pH = 7.35] (KF-gel), and 5000 ppm F− [pH = 8.14]; (NaF-TP) for 7 days (E1). Subsequently, from each specimen, one lesion was covered, while the remaining lesion was cycled for another 7 days (E2). Differences in integrated mineral loss (ΔΔZE1/ΔΔZE2) were calculated between values before and after pH cycling.
Results
Mean (95%CI) ΔZB was 3851 (3762;3939) vol% × μm. Except for NaF-gel2 and NaF-TP, specimens of all other groups further demineralized. Only NaF-gel2 induced a significant gain in mineral content (p ≤ 0.004; paired t test). Significant differences in the change of mineral loss were found between NT and all fluoride groups for both ΔΔZE1 and for ΔΔZE2 (p < 0.05, Bonferroni post hoc test). However, only NaF-gel2 and NaF-TP induced remineralization.
Conclusion
Under the in vitro conditions chosen, all fluoride agents could significantly hamper the adverse effects of a demineralizing saliva substitute.
Clinical significance
In combination with a demineralizing saliva substitute, slight mineral gain was only observed for neutral NaF-gel2 and 5000 ppm F− toothpaste.

Changes of disc status in adult patients with condylar head fracture who did or did not undergo disc anchoring operation
Views on treatment procedures for condylar head fractures (CHFs) are far from reaching a consensus. The aim of this study was to evaluate the changes in disc status for anteromedial disc displacement with anchorage (AMDDwA) and without anchorage (AMDDwoA — just suturing to the adjacent TMJ soft tissue) in adult CHFs, to get a better understanding of this very complex process and to show that rigid disc anchorage is an essential technique for the treatment of CHF during the open reduction and internal fixation (ORIF).

Bone-anchored maxillary protraction in patients with unilateral complete cleft lip and palate and Class III malocclusion
Abstract
Objective
This prospective controlled study evaluated the effect of bone-anchored maxillary protraction therapy in cleft children with Class III malocclusion using CBCT-derived 3D surface models.
Materials and subjects
Eighteen cleft patients between 10 and 12 years old were included. Intermaxillary elastics were worn after the placement of four zygoma bone plates for 18 months. Uniquely, three age-matched untreated groups including both cleft subjects and non-cleft subjects with Class III malocclusion served as controls. Profile photos and CBCT scans for each patient were taken before (T0) and 18 months after the protraction (T1). 3D measurements were made on CBCT surface models from the treatment group using tomographic color mapping method. Cephalometric measurements were made on lateral cephalogram reconstructed from the CBCT scans and were compared with those obtained from the control groups.
Results
Two thirds of the treatment subjects showed improved lip projection towards more convex facial profile. The most significant skeletal changes on 3D surface models were observed at the zygomatic regions (mean 1.5-mm forward, downward, and outward displacement) and at the maxillary complex (mean 1.5-mm forward displacement). Compared with the control groups, the treatment subjects showed significant increase in the SNA and ANB angles, increased Wits appraisal, a more forward movement of point A and overjet improvement (p < 0.05).
Conclusions
BAMP in cleft patients gives a significant forward displacement of the zygomaxillairy complex in favor of the Class III treatment.
Clinical relevance
This treatment method shows clearly favorable outcome in cleft patients after 1.5 years of BAMP.

Predicting the therapeutic effect of carbamazepine in trigeminal neuralgia by analysis of neurovascular compression utilizing magnetic resonance cisternography
The aim of this study was to determine whether the evaluation of neurovascular compression (NVC) using new criteria on magnetic resonance (MR) cisternography improves the prediction of the curative effects of carbamazepine (CBZ) in trigeminal neuralgia (TN). In this study, a new analysis of NVC using MR cisternography was performed retrospectively for 280 patients with clinical signs and symptoms suggesting TN. The new analysis examined whether the site of the NVC was less than 3mm from the edge of the exit point and within the first third of the root entry zone on MR cisternography.

Prevention and detection of prosthetic temporomandibular joint infections—update
Prosthetic joint infections are not only distressing complications for patients and surgeons, but also have an enormous financial impact on healthcare systems. The reported incidence of prosthetic joint infection is likely underestimated due to difficulties in their diagnosis. This unfortunate complication has challenged joint replacement surgeons for years, despite all the advances made in this surgical discipline. Since eradication of these infections can be very difficult, prevention remains the primary objective.

Intraoperative augmented reality with heads-up displays in maxillofacial surgery: a systematic review of the literature and a classification of relevant technologies
Although the term augmented reality appears increasingly in published studies, the real-time, image-guided (so-called 'hands-free' and 'heads-up') surgery techniques are often confused with other virtual imaging procedures. A systematic review of the literature was conducted to classify augmented reality applications in the fields of maxillofacial surgery. Publications containing the terms 'augmented reality', 'hybrid reality', and 'surgery' were sought through a search of three medical databases, covering the years 1995–2018.

Core Outcome Sets for Psoriasis Clinical Trials
Standardized and relevant psoriasis-specific outcome measures would contribute to a better understanding of the benefits of a growing list of highly effective therapies. To this end, in this issue of JAMA Dermatology, Callis Duffin et al present the results of an effort to define core outcome sets (COSs) for clinical trials of psoriasis. Under the auspices of the International Dermatology Outcome Measures group, the authors conducted a Delphi survey and determined that the following 6 domains should be addressed in all psoriasis trials: (1) psoriatic skin manifestations (including location), (2) an investigator global assessment, (3) an evaluation of signs and symptoms of both psoriasis and psoriatic arthritis, (4) a patient global assessment of his or her condition, (5) an assessment of treatment satisfaction, and (6) a measure of health-related quality of life.

Performance of Dermatology Physician Assistants—Reply
In Reply We thank Marghoob et al for the opportunity to address their concerns regarding our study. Number needed to biopsy (NNB) (or excise) is a well-established measure consistent with prior publications, including studies by Marghoob and colleagues. While NNB can vary with disease prevalence, patients in both cohorts in our study had similar rates of keratinocyte carcinomas and invasive melanomas. Patients were also similarly distributed by age and sex, and our NNB findings remained consistent when patients with a melanoma history were excluded.

Observation of Moderately Dysplastic Nevi With Positive Margins
The management of dysplastic nevi is a quotidian part of the clinical practice of dermatology, yet even directors of pigmented lesion clinics in the United States demonstrate significant practice variation with observation or therapeutic excision of dysplastic nevi. This scenario is particularly true for biopsies of dysplastic nevi that have histologically positive margins. A 2015 consensus statement summarizing this practice gap included a call for further study of this common clinical question. There are several important challenges in establishing evidence-based guidelines for the management of dysplastic nevi, and thus establishing practice consensus for the management of dysplastic nevi, including the lack of definitive evidence that dysplastic nevi are precursor lesions to melanoma, interobserver histopathologic variation in gradation of dysplasia, longitudinal risk of monitoring for clinical recurrence, and variation in diagnostic biopsy procedures (ie, risk of incisional or partial biopsies).

Clinical manifestations of hydropic ear disease (Menière’s)
Abstract
Introduction
Hydropic ear disease, initially described by and named after Prosper Menière, is one of the most frequent vertigo disorders and one of the most frequent inner ear disorders. It is the syndrome of endolymphatic hydrops which until 2007 could be diagnostically confirmed only by post-mortem histology. In the past, various attempts to formulate clinical diagnostic criteria have been undertaken but were hampered by the inability to ascertain the diagnosis in living patients. With the milestone achievement of endolymphatic hydrops imaging, today the pathology can be ascertained. In this study, we have performed a detailed analysis of the clinical features of hydropic ear disease for the first time by examining a large cohort of patients with morphologically confirmed endolymphatic hydrops using a detailed physician-administered neurotologic face-to-face interview.
Results
During a hydropic vertigo attack, the patients report nausea, vomiting, sweating, urge to defecate, urge to urinate, phosphenes, headache, photophobia, phonophobia and even transient loss of consciousness. A third of the patients does not experience auditory symptoms during the vertigo attacks. Vertigo attacks last less than 20 min in more than one-fourth of the patients. Audiometric hearing loss has its greatest diagnostic value at the frequencies of 1 kHz and below. Cochleovestibular symptom onset simultaneity is associated with a high frequency of drop-attacks. Migraine and autoimmune disorders are not associated with hydropic ear disease.
Conclusion
This study marks the beginning of the clinical characterization of hydropic ear disease. The findings have important implications for the future formulation of clinical diagnostic criteria.

Morphometric properties of the facial nerve in fetal temporal bones
Publication date: Available online 10 October 2018
Source: International Journal of Pediatric Otorhinolaryngology
Author(s): Derya Ümit Talas, Orhan Beger, Turan Koç, Vural Hamzaoğlu, Hakan Özalp, Melike Mavruk, Cemre Yıldırım, İrem Güzelyüz, Yusuf Vayisoğlu, Deniz Uzmansel, Mehmet Farsak, Ahmet Dağtekin
Abstract
Objectives
The main aim of the study was to examine the development and course of the facial nerve within fetal temporal bones from an anatomical and neuro-otological perspective.
Methods
The study was conducted on 32 temporal bones from obtained fetuses (7 females, 9 male), on a mean gestational age of 26.75±4.36 (range, 20-34) weeks from the collection of the Anatomy Department of Medicine Faculty. All the measurements were collected with a digital image analysis software.
Results
Neither male/female nor right/left significant differences were observed in relation with the algebraic data of the segment lengths and angles of the facial nerve (p > 0.05). Linear functions for meatal, labyrinthine, tympanic, and mastoid segment lengths of the facial nerve were calculated as: y = -1.206 + 0.200 x Age (weeks), y = -1.868 + 0.153 x Age (weeks), y = -2.327+ 0.325 x Age (weeks), and y = -1.507+ 0.246 x Age (weeks), respectively. In addition, linear functions for first and second genu angles were calculated as: y = 105.475 - 0.117 x Age (weeks) and y = 140.446 - 0.042 x Age (weeks), respectively.
Conclusion
The regression equations and the scatter plot with increment curve, representing the growth dynamics of the facial nerve can be used for estimating its lengths and for understanding its development. The data suggest that there is a dramatic change transition from fetal life to the gathered data of adulthood in the length of meatal and mastoid segments as well as in the second genu angle; in addition, there is a partial change in the length of labyrinthine and tympanic segments as well as in the first genu angle.

Transcriptome analysis of differentially expressed genes involved in innate immunity following Bacillus thuringiensis challenge in Bombyx mori larvae
Publication date: November 2018
Source: Molecular Immunology, Volume 103
Author(s): Gongqing Wu, Yunhong Yi
Abstract
In this study, we describe RNA-seq expression profiling of larval Bombyx mori response to hemocoel injection of Bacillus thuringiensis (Bt). Two transcriptomes were generated from the hemocytes of the PBS- and Bt-injected B. mori larvae. More than 49 million 100-bp paired-end reads, encompassing over 7.3 Gb of sequence data, were generated for each library. After filtering the raw reads and removing the rRNA mapped reads, more than 89% of the reads in each library could be mapped to the silkworm genome reference sequence. Comparison of gene expression levels revealed that a total of 133 unigenes were upregulated while 84 unigenes were downregulated in PBS vs Bt. To further investigate the biological functions of different expression genes (DEGs), gene ontology (GO) and functional enrichment analysis were performed to map all the DEGs to terms in the GO, euKaryotic Ortholog Groups of proteins (KOG) and Kyoto Encyclopedia of Genes and Genomes Pathway (KEGG) database. Among these DEGs, many genes involved in immunity against Bt challenge were identified. These included genes participated in pattern recognition, antimicrobial peptides, insecticide resistance or detoxification, immune melanization, cytoskeleton reorganization and many other immune effectors. To confirm the gene expression patterns identified by the RNA-seq data, the transcript levels of 10 immune related DEGs were examined by quantitative real-time PCR (qRT-PCR). The results showed that the DEGs obtained from the deep sequencing data were accurate and gene expression profiles from RNA-Seq data were reliable. Our studies provide insights into the to immune response of B. mori underling the stress of Bt, which is valuable to understand how Bt affects the innate immune system of silkworm and provide new approaches to control insect pests by using Bt as a biological insecticide.

Short Summary
The phagocyte respiratory burst is mediated by the phagocyte NADPH oxidase, a multi-protein subunit complex that facilitates production of reactive oxygen species and which is essential for host defence. Monogenic deficiency of individual subunits leads to chronic granulomatous disease (CGD), which is characterized by an inability to make reactive oxygen species, leading to severe opportunistic infections and auto-inflammation. However, not all cases of CGD are due to mutations in previously identified subunits. We recently showed that Eros, a novel and highly conserved ER-resident transmembrane protein, is essential for the phagocyte respiratory burst in mice because it is required for expression of gp91phox-p22phox heterodimer, which are the membrane bound components of the phagocyte NADPH oxidase. Eros has a human orthologue, CYBC1/EROS. We now show that the function of CYBC1/EROS is conserved in human cells and describe a case of CGD secondary to a homozygous CYBC1/EROS mutation that abolishes EROS protein expression. This work demonstrates the fundamental importance of CYBC1/EROS in human immunity and describes a novel cause of CGD.

Real life treatment of Cholinergic Urticaria with Omalizumab
Publication date: Available online 9 October 2018
Source: Journal of Allergy and Clinical Immunology
Author(s): S. Altrichter, M. Chuamanochan, H. Knoth, A. Asady, T. Ohanyan, M. Metz, M. Maurer
Abstract
Background
Cholinergic urticaria (CholU), a frequent type of chronic inducible urticaria, presents with small itchy wheals upon physical exercise or passive warming. Omalizumab has been shown to be very effective in patients with chronic spontaneous urticaria. Whether or not omalizumab is also effective in CholU is largely unknown.
Aim
To assess the effectiveness of omalizumab treatment in CholU
Method
We assessed the effects of real life omalizumab treatment at standard and higher than standard doses in CholU patients including their time to response, the effects on concomitant urticaria forms and links to clinical features.
Results
Of 16 CholU patients treated with omalizumab, 11 (68%) reported a major or complete response, 2 patients reported a minor effect (13 %) and 3 patients (19%) showed no benefit. Omalizumab updosing led to complete response in 4 of 6 patients, who did not achieve controlled disease on standard dosed omalizumab therapy, i.e. 300 mg/4wks. Time to onset of benefit was fast, and concomitant urticaria forms showed similar response patterns. Treatment effects were linked to patient gender, with better responses in female patients (p < 0.05), but not patient age, age at onset of disease, duration of disease, or total IgE serum levels.
Conclusion
Omalizumab treatment is effective in the majority of CholU patients, especially in female patients. Most non-responders to standard-dosed omalizumab benefit from updosing. Our findings call for controlled clinical trials of omalizumab and other IgE-targeted treatments in CholU.

Impact of bisphosphonate therapy on dental implant outcomes: An overview of systematic review evidence
Publication date: Available online 9 October 2018
Source: International Journal of Oral and Maxillofacial Surgery
Author(s): V. Mendes, G.O. dos Santos, M.D. Calasans-Maia, J.M. Granjeiro, V. Moraschini
Abstract
The purpose of this overview was to assess the methods, quality, and outcomes of systematic reviews conducted to evaluate the impact of bisphosphonates on dental implants and the risk of developing bisphosphonate-related osteonecrosis of the jaw after dental implant surgery. An electronic search without date or language restriction was performed in the PubMed/MEDLINE, Cochrane CENTRAL, Web of Science, and LILACS databases (to January 2018). Eligibility criteria included systematic reviews that evaluated the impact of bisphosphonates on implant outcomes. The quality assessment of the included reviews was done using AMSTAR 2 guidelines. The protocol of this overview was registered in PROSPERO (CRD42018089617). The search and selection process yielded seven reviews, published between 2009 and 2017. None of the systematic reviews included in this study obtained the maximum score in the quality assessment. The scientific evidence available demonstrates that patients with a history of bisphosphonate use do not present a higher risk of dental implant failure or marginal bone loss compared to patients who have not used bisphosphonates. The literature also suggests that patients who undergo surgical trauma during the installation of dental implants may be more susceptible to bisphosphonate-related osteonecrosis of the jaw.

Author(s): F. Cullati, F.M.E. Rusconi, A. Mapelli, M. Zago, G.A. Beltramini, A.B. Giannì, C. Sforza
Abstract
The effect of bimaxillary orthognathic surgery on facial mimicry was assessed longitudinally in 15 patients with dentoskeletal class III facial dysmorphism (seven men, eight women, mean age 28 years). The patients were analysed pre-surgery and at 6, 12, and 24 months post-surgery while performing verbal (five vowels) and non-verbal (open and closed mouth smile, lip purse) soft tissue facial movements. The three-dimensional motions of right and left nasogenian, crista philtri, cheilion, and lower lip landmarks were detected by an optoelectronic instrument, and a total mobility index was obtained. Differences between the sides were quantified by the symmetry index. Patient values were compared to those collected previously from healthy volunteers by computing z-scores. On average, no significant differences were found in the mobility of the buccal soft tissues at 24 months after surgery (ANOVA P-value, range 0.075–0.808), with positive median z-scores (pooled mean value close to 0.6). Symmetry indices ranged around the control reference values, showing no stage-related differences (Friedman test P-value, range 0.252–0.937), and exceeding 90% for all movements at 24 months after surgery. Bimaxillary osteotomy does not compromise facial mimicry in either verbal or non-verbal facial movements.

Does methylprednisolone improve postoperative outcomes after mandibular third molar surgery? A systematic review and meta-analysis
Publication date: Available online 9 October 2018
Source: International Journal of Oral and Maxillofacial Surgery
Author(s): Shakil Ahmed Nagori, Anson Jose, Indranil Deb Roy, Probodh K. Chattopadhyay, Ajoy Roychoudhury
Abstract
This systematic review and meta-analysis was performed to investigate whether methylprednisolone (MP) administered via any route improves postoperative outcomes (pain, trismus, and oedema) following mandibular third molar surgery. An electronic search of the PubMed, Scopus, Cochrane CENTRAL, and Google Scholar databases was performed to identify studies published in English up until January 2018. A total of 28 studies were included in the review: 25 randomized clinical trials (RCTs) and three controlled clinical trials. Studies were grouped according to the route of administration of MP for qualitative and quantitative analysis. Three studies were of 'high' quality and 22 were of 'medium' quality; three studies had a high risk of bias. Within the purview of the limitations of this review, the results showed that MP administered via any route significantly improves oedema in the early postoperative period, but has no effect on late postoperative oedema. Oral and intra-masseteric MP also seems to reduce pain and trismus in the early postoperative period. The results also indicate that oral MP may reduce late postoperative pain, while intra-masseteric MP may improve the late trismus outcome. More high quality RCTs are required to provide stronger evidence on the use of MP in third molar surgery.

The effect of human serum and dentin powder alone or in combination on the antibacterial activity of sodium hypochlorite against Enterococcus faecalis
Publication date: Available online 9 October 2018
Source: Archives of Oral Biology
Author(s): Zhongchun Tong, Yanqing Zhang, Xi Wei
Abstract
Objective
Dentin debris and organic components may affect the properties of intracanal irrigants. This study aimed to evaluate the effect of dentin powder (DP) and human serum (HS) on the antibacterial and antibiofilm activity of sodium hypochlorite (NaOCl) against Enterococcus faecalis.
Design
DP from 100 to 6.25 mg/mL and HS from 10% to 0.3125% were interactively mixed and added into E. faecalis and 1% NaOCl solution. The live E. faecalis were counted after 1 min of contact. For biofilm testing, 7 days of E. faecalis biofilms were treated by 100 mg/mL DP and 10% HS alone or combination with 1% NaOCl solution for 1 min. Furthermore, after challenges, E. faecalis biofilms were stained with SYTO 9 and propidium iodide, and confocal laser scanning microscopy (CLSM) was used to determine the proportion of dead and live cells in the biofilm.
Results
One hundred mg/mL DP or 10% HS alone showed the excellent inhibition of 1% NaOCl against planktonic E. faecalis, and the low concentration of DP and HS presented an additive inhibitory effect. The number of live bacteria in biofilms were significantly higher in the 1% NaOCl-treated group with DP or HS than without DP and HS (p < 0.05), and a higher percentage of dead bacteria was found in the challenge of NaOCl in the absence of DP and HS than in the presence of DP and HS.
Conclusion
DP and HS generated the inhibition of antibacterial and antibiofilm activities of NaOCl, whereas the effect of HS was greater than DP.

Résumé
Introduction
Les métastases cutanées (MC) localisées aux extrémités sont des complications exceptionnelles des cancers solides, au pronostic sévère. Dans la majorité des cas, elles simulent une infection. Nous en rapportons deux nouvelles observations de présentation originale.
Observations
Cas no 1 : un homme de 71 ans consultait pour suspicion de botryomycomes de la main gauche évoluant depuis 3 mois. Il avait pour antécédent deux carcinomes épidermoïdes (lingual et pulmonaire) en rémission. L'examen clinique objectivait trois lésions bourgeonnantes de la main gauche. La biopsie d'une des lésions concluait à une métastase de carcinome épidermoïde. Au bilan d'extension, on notait l'apparition de micronodules pulmonaires disséminés suspects de localisations secondaires. Cas no 2 : un homme de 68 ans consultait pour un œdème du membre inférieur droit infiltré, dur, mal limité, qui évoluait depuis plusieurs mois. Six mois auparavant, il avait eu un adénocarcinome bronchique traité par lobectomie supérieure gauche et dont le bilan d'extension ne révélait pas de lésion secondaire. Cliniquement, on notait un œdème induré prédominant au pied. La biopsie cutanée objectivait une métastase d'adénocarcinome. Le bilan d'extension montrait des lésions ostéolytiques du tarse droit ainsi que des adénomégalies.
Discussion
Nous rapportons deux cas originaux de MC des extrémités ayant permis de diagnostiquer une évolution tumorale. Il s'agit d'une complication rare, de présentation clinique variable, ayant un impact sur la prise en charge du cancer et sur le pronostic vital du patient. Ces observations illustrent l'importance d'évoquer le diagnostic en cas de lésions cutanées distales persistantes, a fortiori en cas d'antécédents néoplasiques.
Summary
Background
Cutaneous metastases (CM) on the extremities are rare complication of cancer with poor prognosis. In general, lesions simulate an infection. Herein, we report two new cases with atypical presentation.
Patients and methods
Case no 1: a 71-year-old man consulted for suspicion of left hand pyogenic granuloma present for 3 months. His history revealed two treated squamous-cell carcinomas (tongue and lung). On physical examination, he presented three budding and foul-smelling lesions on his left hand. Histopathology showed metastasis of squamous-cell carcinoma. Radiographic examination revealed spread of pulmonary nodules with suspicion of metastasis. Case no 2: a 68-year-old man was hospitalized for indurated edema of the right leg present for several months. Six months earlier, he had undergone surgery for left pulmonary adenocarcinoma without metastasis. Physical examination revealed an indurated edema on the right foot. Histopathology showed metastasis from adenocarcinoma. A scan revealed several osteolytic lesions in the right foot as well as lymphadenopathy.
Discussion
Herein, we report two original cases of CM of the extremities diagnosed as tumor progression. This is a rare complication of variable clinical presentation and impacts both cancer management and prognosis. It is important to consider the diagnosis when distal cutaneous lesions persist, particularly where there is a history of cancer.

Abstract
Objective
Dentin debris and organic components may affect the properties of intracanal irrigants. This study aimed to evaluate the effect of dentin powder (DP) and human serum (HS) on the antibacterial and antibiofilm activity of sodium hypochlorite (NaOCl) against Enterococcus faecalis.
Design
DP from 100 to 6.25 mg/mL and HS from 10% to 0.3125% were interactively mixed and added into E. faecalis and 1% NaOCl solution. The live E. faecalis were counted after 1 min of contact. For biofilm testing, 7 days of E. faecalis biofilms were treated by 100 mg/mL DP and 10% HS alone or combination with 1% NaOCl solution for 1 min. Furthermore, after challenges, E. faecalis biofilms were stained with SYTO 9 and propidium iodide, and confocal laser scanning microscopy (CLSM) was used to determine the proportion of dead and live cells in the biofilm.
Results
One hundred mg/mL DP or 10% HS alone showed the excellent inhibition of 1% NaOCl against planktonic E. faecalis, and the low concentration of DP and HS presented an additive inhibitory effect. The number of live bacteria in biofilms were significantly higher in the 1% NaOCl-treated group with DP or HS than without DP and HS (p < 0.05), and a higher percentage of dead bacteria was found in the challenge of NaOCl in the absence of DP and HS than in the presence of DP and HS.
Conclusion
DP and HS generated the inhibition of antibacterial and antibiofilm activities of NaOCl, whereas the effect of HS was greater than DP.

The protective effect of metformin against the noise-induced hearing loss
Abstract
Objective
To test the protective effect of metformin against noise-induced hearing loss.
Methods
24 rats were included in the study. The first group was exposed to noise only, the second group took metformin, the third group was exposed to noise and took metformin, and the fourth group was neither exposed to noise nor took metformin as control group. After measurement of baseline DPOAE and ABR of rats, the metformin group and the metformin + noise group received 300 mg/kg/day metformin via gavage for 10 days. On the 11th day, group 1 and group 3 were exposured to white noise at 105 dB SPL for 15 h. After noise exposure, DPOAE and ABR measurements of all rats were repeated on days 1st, 7th, and 21st. At the end of the study, all animals were sacrificed and cochlear tissues were separated for immunohistochemical assessments.
Results
ABR threshold values and DPAOE measurements of groups 1 and 3 were deteriorated on the 1st day after noise, while deterioration in group 1 continued on 7th and 21st days, but normalized on 7th day in group 3. After immune staining, a significant immunoreaction was observed in the noise group, while the reaction in the noise + metformin group was close to the control group.
Conclusion
Metformin has a protective effect on noise-induced hearing loss in rats. As a conclusion, it is determined that metformin protects from permanent threshold shift in rats. It can be considered a good alternative for protecting noise-induced hearing loss.

Macrophage-microbe interaction: lessons learned from the pathogen Mycobacterium tuberculosis
Abstract
Macrophages, being the cornerstone of the immune system, have adapted the ancient nutrient acquisition mechanism of phagocytosis to engulf various infectious organisms thereby helping to orchestrate an appropriate host response. Phagocytosis refers to the process of internalization and degradation of particulate material, damaged and senescent cells and microorganisms by specialized cells, after which the vesicle containing the ingested particle, the phagosome, matures into acidic phagolysosomes upon fusion with hydrolytic enzyme-containing lysosomes. The destructive power of the macrophage is further exacerbated through the induction of macrophage activation upon a variety of inflammatory stimuli. Despite being the end-point for many phagocytosed microbes, the macrophage can also serve as an intracellular survival niche for a number of intracellular microorganisms. One microbe that is particularly successful at surviving within macrophages is the pathogen Mycobacterium tuberculosis, which can efficiently manipulate the macrophage at several levels, including modulation of the phagocytic pathway as well as interfering with a number of immune activation pathways that normally would lead to eradication of the internalized bacilli. M. tuberculosis excels at circumventing destruction within macrophages, thus establishing itself successfully for prolonged times within the macrophage. In this contribution, we describe a number of general features of macrophages in the context of their function to clear an infection, and highlight the strategies employed by M. tuberculosis to counter macrophage attack. Interestingly, research on the evasion tactics employed by M. tuberculosis within macrophages not only helps to design strategies to curb tuberculosis, but also allows a better understanding of host cell biology.

Differences in the subgingival microbial population of chronic periodontitis in subjects with and without type 2 diabetes mellitus—a systematic review
Abstract
Objectives
The purpose of this systematic review was to evaluate the available evidence in the literature in regard to the subgingival microbial population of chronic periodontitis in subjects with type 2 diabetes mellitus (T2DM+PD) compared to non-diabetic subjects (NDM+PD).
Materials and methods
A literature search was conducted at Ovid MEDLINE and EMBASE database from 1980 to 2016, supplemented by hand searching as needed. Studies presenting with at least one of the primary outcomes (presence of any subgingival microorganisms, proportion and/or the amount of any subgingival plaque bacteria in T2DM+PD versus NDM+PD) were included. Screening, data extraction and quality assessment were conducted independently and in duplicate.
Results
From 611 citations, 19 full-text papers were screened and 11 articles were included for critical appraisal by both reviewers. Some evidence of a difference in the microbial profile between chronic PD subjects with and without T2DM was identified. The strength of evidence is strongest in Tannerella forthysia (T .forsythia) which was reported to be less frequent in the diabetic (T2DM+PD) group in five of the studies, followed by a weaker strength of evidence for other periodontal pathogens such as Porphyromonas gingivalis (P. gingivalis) and Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans), which were also found less frequent in the diabetic (T2DM+PD) group .
Conclusion
Only few studies have compared T2DM+PD with NDM+PD. It is therefore strongly recommended that further studies which include four distinct groups of participants (NDM+PD, T2DM+PD, NDM+NPD, T2DM+NPD) instead of using intra-subject comparisons between healthy and diseased sites of the same subjects.
Clinical relevance
Differences in bacterial populations of T2DM+PD in comparison to NDM+PD subjects may indicate the need of different protocols for the treatment of the diabetic patients with periodontal disease.

Abstract
Objectives
Cochlear implants (CI) have enabled an increasing proportion of deaf children to develop oral communication. Despite the well-known benefits of bilateral implantation, many of these children and teenagers have only a unilateral implant. The aim of this study was to evaluate the benefits of sequential bilateral CI and the influence of relevant factors on outcome.
Material and methods
A single-center retrospective study included 109 children and adolescents who received a second sequential CI between 2008 and 2016. Subjects were evaluated before sequential implantation and subsequently at 3, 12 and 24 months, on Speech Intelligibility Rating and speech perception tests: Categories of Auditory Performance, word and sentence recognition in silence and in noise. The influence of inter-implant interval and performance with the first CI were analyzed.
Results
In the majority of patients, sequential CI provided significant improvement in speech and intelligibility perception. These benefits were seen not only for short but also for long inter-implant intervals. Some subjects with poor performance with their first implant showed significant progression after sequential bilateral implantation.
Conclusion
In view of the benefits of sequential bilateral CI, we suggest that a second CI should be proposed to all unilaterally implanted children and adolescents, regardless of inter-implant interval and initial performance with the first CI. Further studies need to be conducted to identify prognostic factors for success in sequential contralateral implantation.

Endovascular Management of a Refractory Pseudoaneurysm of the Sternocleidomastoid Artery Caused by Attempted Internal Jugular Central Line Placement with Long-Term Follow-Up: A Case Report and Review
Introduction. This case report shows successful treatment of a refractory sternocleidomastoid branch of the superior thyroid artery (SBSTA) pseudoaneurysm using endovascular glue embolization in a patient who refused surgery. Case Presentation. A 63-year-old female with multiple comorbidities presented with a firm 7 cm tender mass located in the right neck. Ultrasound showed pseudoaneurysm and a 7 × 3.3 × 4 cm multilobular hematoma in the location of the previous central line. CTA showed a corresponding heterogeneous mass. Serial imaging demonstrated enlargement over 2 weeks. Angiogram showed contrast blush off of the SBSTA. Management and Outcome. SBSTA was embolized using glue. Repeat angiogram showed embolization and no contrast blush. One month later, the mass was no longer pulsatile but present on physical exam. CTA showed decreased size. 8 months later, her neck was soft without mass. Discussion. Pseudoaneurysms of the external carotid artery are rare and usually due to trauma. Pseudoaneurysms after central line placement are documented, but most are complications of femoral central lines. A handful of cases of superior thyroid artery pseudoaneurysms due to several etiologies are reported, but none involving the SBSTA. Therapeutic options include surveillance, compression, thrombin injection, embolization, and surgery. Endovascular management offers an alternative for patients unwilling or unable to undergo open surgery.

The Comorbidity Burden of Hidradenitis Suppurativa in the United States: A Claims Data Analysis
Abstract
Introduction
Prior studies have reported that hidradenitis suppurativa (HS) is accompanied by a myriad of physical and mental conditions. However, given the small sample sizes and the limited number of pre-selected comorbidities, these studies do not provide a complete picture of the comorbidity burden of HS in the USA. Moreover, the relationship between HS severity and comorbidity burden has yet to be characterized. Using a large US claims database, we estimated the comorbidity burden associated with HS, stratified by disease severity.
Methods
A retrospective matched cohort design was used. Patients with HS were classified into two severity cohorts (milder and more severe) using an empirical algorithm based on treatments received. The comorbidity burden was compared between each HS cohort and their matched HS-free cohort, and between patients with milder vs. those with more severe forms of HS.
Results
Several physical and mental comorbidities were found to be more prevalent in both cohorts of patients with milder and more severe forms of HS than in their matched HS-free cohorts. The comorbidity burden also increased greatly as the disease progressed to more severe forms.
Conclusions
The results of this study highlight the complexity of the comorbidity burden of HS patients and the need for a multidisciplinary approach to optimize the management of HS and its numerous associated comorbidities.

Abstract
Background
Hereditary angioedema with C1 inhibitor deficiency (C1-INH-HAE) is a rare, potentially life-threatening disorder characterized by recurrent edematous attacks. The edema formation is the consequence of interaction of bradykinin and various vasoactive peptides with endothelium. Besides these agents, danazol, a modified testosterone derivative used in these patients to prevent edematous attacks, can also affect the function of the endothelium, since it shifts the blood lipid profile to a pro-atherogenic phenotype.
Objective
To assess the endothelial function in C1-INH-HAE patients and in healthy matched controls.
Methods
To evaluate the endothelial function, we used the flow mediated dilation method measured in the region of the brachial artery in 33 C1- INH-HAE patients and in 30 healthy matched controls. Laboratory measurements of standard biochemical parameters were performed on computerized laboratory analyzers.
Results
There was no difference in endothelial function (reactive hyperaemia, RH) between patients (median 9.0, 25-75% percentile 6.3-12.9) and controls (median 7.37, 25-75% percentile 4.52-9.93). Although we found elevated cardiovascular risk (high BMI and LDL/HDL ratio) in danazol treated C1-INH-HAE patients, RH values did not differ between danazol treated and non-treated patients. Furthermore, risk factors correlated with the endothelial function only in healthy controls and patients not treated with danazol.
Conclusion
In summary, our results did not indicate any signs of endothelial dysfunction in C1-INH-HAE patients. Moreover, the normal endothelial function in danazol treated patients with pro-atherogenic lipid profile suggests that elevated bradykinin level or other factor(s) involved in the pathogenesis of edematous attacks may have a protective role against endothelial dysfunction and atherosclerosis.

Contemporary Academic Contributions From Anesthesiologists in Adult Critical Care Medicine
BACKGROUND: Anesthesiology has a long relationship with critical care medicine (CCM). However, US anesthesiologists are less likely to practice CCM than non-US anesthesiologists. To date, no studies have compared academic contributions in CCM between US anesthesiologists and non-US anesthesiologists. The objective of our study was to use recent trends in critical care publications as a surrogate for academic contribution among US and non-US anesthesiologists. METHODS: Research articles published between 2010 and 2015 in 3 anesthesiology journals (Anesthesiology, Anesthesia & Analgesia, and British Journal of Anaesthesia) and 3 multidisciplinary CCM journals (Critical Care Medicine, Intensive Care Medicine, and Journal of Critical Care) were reviewed. Author information, including the primary department appointment and geographic location for the first and senior author(s), and article details, including topic and publication type, were collected. Odds ratios for having a first or senior author from the United States were calculated. Anesthesiologists' contributions in individual journals were summarized, as were trends in anesthesiology CCM publications during the 6-year study period. RESULTS: A total of 3831 articles were reviewed, with 1050 (27.4%) having US authors. Eighty-two and one-half percent of CCM articles in anesthesiology journals had a US anesthesiologist as first author, and 81% had a US anesthesiologist as senior author, while fewer CCM articles in multidisciplinary journals had a US anesthesiologist as first (12.1%) or senior (12.3%) author. When considering all publications, 16.3% and 16.4% of articles had a US anesthesiologist as the first or senior author compared with articles for which non-US anesthesiologists were first (23.8%) or senior (20.9%) authors. The odds of having a US anesthesiologist as first or senior author compared to a non-US anesthesiologist for all publications were 0.6 (0.5–0.7) and 0.7 (0.6–0.9). The number of publications trended downward for both US anesthesiologists and non-US anesthesiologists during the study period. CONCLUSIONS: When compared to non-US anesthesiologists, US anesthesiologists had more CCM publications in anesthesiology journals and fewer publications in multidisciplinary CCM journals. The number of anesthesiology CCM publications decreased for both US and non-US anesthesiologists throughout the study period. Accepted for publication September 5, 2018. Funding: None.

Intensive Care Unit Readmission After Left Ventricular Assist Device Implantation: Causes, Associated Factors, and Association With Patient Mortality
BACKGROUND: Previous studies on readmissions after left ventricular assist device (LVAD) implantation have focused on hospital readmissions after dismissal from the index hospitalization. Because few data exist, the purpose of this study was to examine intensive care unit (ICU) readmissions in patients during their initial hospitalization for LVAD implantation to determine reasons for, factors associated with, and incidence of mortality after ICU readmission. METHODS: A retrospective analysis was performed from February 2007 to March 2015 of patients at our institution receiving first-time LVAD implantation. After LVAD implantation, patients dismissed from the ICU who then required ICU readmission before hospital dismissal were compared to those not requiring ICU readmission before hospital dismissal with respect to preoperative, intraoperative, and postoperative factors. RESULTS: Among 287 LVAD patients, 266 survived their initial ICU admission, of which 49 (18.4%) required ICU readmission. The most common reasons for readmission were bleeding and respiratory failure. Factors found to be univariably associated with ICU readmission were preoperative hemoglobin, preoperative aspartate aminotransferase, preoperative atrial fibrillation, preoperative dialysis, longer cardiopulmonary bypass times, and higher intraoperative allogeneic blood transfusion requirements. Multivariable analysis revealed ICU readmission to be independently associated with preoperative dialysis (odds ratio, 12.86; 95% confidence interval, 3.16–52.28; P

Recognizing the Chinese Pioneer of Neuraxial Labor Analgesia: Dr Guang-Bo Zhang and Her Unpublished Manuscript From More Than a Half-Century Ago
Dr Guang-Bo Zhang was the first anesthesiologist to administer and study the effects of labor epidural analgesia in China. Between September 1963 and March 1964, she conducted an observational study evaluating the effects of neuraxial analgesia for laboring women. She presented her research and prepared an article; however, due to the Great Proletarian Cultural Revolution (Cultural Revolution), which began in 1966, her work went unpublished. She successfully preserved her unpublished article, notes, and slides throughout the Cultural Revolution by hiding them in a countryside location near Beijing. These 54-year-old, previously unpublished documents represent the first known clinical trial of neuraxial labor analgesia conducted in China. Accepted for publication Septermber 5, 2018.

Emergency Department Airway Management Responsibilities in the United States
BACKGROUND: In the 1990s, emergency medicine (EM) physicians were responsible for intubating about half of the patients requiring airway management in emergency rooms. Since then, no studies have characterized the airway management responsibilities in the emergency room. METHODS: A survey was sent via the Eastern Association for Surgery and Trauma and the Trauma Anesthesiology Society listservs, as well as by direct solicitation. Information was collected on trauma center level, geographical location, department responsible for intubation in the emergency room, department responsible for intubation in the trauma bay, whether these roles differed for pediatrics, whether an anesthesiologist was available "in-house" 24 hours a day, and whether there was a protocol for anesthesiologists to assist as backup during intubations. Responses were collected, reviewed, linked by city, and mapped using Python. RESULTS: The majority of the responses came from the Eastern Association for Surgery of Trauma (84.6%). Of the respondents, 72.6% were from level-1 trauma centers, and most were located in the eastern half of the United States. In the emergency room, EM physicians were primarily responsible for intubations at 81% of the surveyed institutions. In trauma bays, EM physicians were primarily responsible for 61.4% of intubations. There did not appear to be a geographical pattern for personnel responsible for managing the airway at the institutions surveyed. CONCLUSIONS: The majority of institutions have EM physicians managing their airways in both emergency rooms and trauma bays. This may support the observations of an increased percentage of airway management in the emergency room and trauma bay setting by EM physicians compared to 20 years ago.

Fluid Challenge During Anesthesia: A Systematic Review and Meta-analysis
BACKGROUND: Assessing the volemic status of patients undergoing surgery is part of the routine management for the anesthesiologist. This assessment is commonly performed by means of dynamic indexes based on the cardiopulmonary interaction during mechanical ventilation (if available) or by administering a fluid challenge (FC). The FC is used during surgery to optimize predefined hemodynamic targets, the so-called Goal-Directed Therapy (GDT), or to correct hemodynamic instability (non-GDT). METHODS: In this systematic review, we considered the FC components in studies adopting either GDT or non-GDT, to assess whether differences exist between the 2 approaches. In addition, we performed a meta-analysis to ascertain the effectiveness of dynamic indexes pulse pressure variation (PPV) and stroke volume (SV) variation (SVV), in predicting fluid responsiveness. RESULTS: Thirty-five non-GDT and 33 GDT studies met inclusion criteria, including 5017 patients. In the vast majority of non-GDT and GDT studies, the FC consisted in the administration of colloids (85.7% and 90.9%, respectively). In 29 non-GDT studies, the colloid infused was the 6% hydroxyethyl starch (6% HES; 96.6% of this subgroup). In 20 GDT studies, the colloid infused was the 6% HES (66.7% of this subgroup), while in 5 studies was a gelatin (16.7% of this subgroup), in 3 studies an unspecified colloid (10.0% of this subgroup), and in 1 study albumin (3.3%) or, in another study, both HES 6% and gelatin (3.3%). In non-GDT studies, the median volume infused was 500 mL; the time of infusion and hemodynamic target to assess fluid responsiveness lacked standardization. In GDT studies, FC usually consisted in the administration of 250 mL of colloids (48.8%) in 10 minutes (45.4%) targeting an SV increase >10% (57.5%). Only in 60.6% of GDT studies, a safety limit was adopted. PPV pooled area under the curve (95% confidence interval [CI]) was 0.86 (0.80–0.92). The mean (standard deviation) PPV threshold predicting fluid responsiveness was 10.5% (3.2) (range, 8%–15%), while the pooled (95% CI) sensitivity and specificity were 0.80 (0.74–0.85) and 0.83 (0.73–0.91), respectively. SVV pooled area under the curve (95% CI) was 0.87 (0.81–0.93). The mean (standard deviation) SVV threshold predicting fluid responsiveness was 11.3% (3.1) (range, 7.5%–15.5%), while the pooled (95% CI) sensitivity and specificity were 0.82 (0.75–0.89) and 0.77 (0.71–0.82), respectively. CONCLUSIONS: The key components of FC including type of fluid (colloids, often 6% HES), volume (500 and 250 mL in non-GDT studies and GDT studies, respectively), and time of infusion (10 minutes) are quite standardized in operating room. However, pooled sensitivity and specificity of both PPV and SVV are limited. Accepted for publication August 27, 2018. Funding: None. Conflicts of Interest: See Disclosures at the end of the article.

Resting Hemodynamics and Response to Exercise Using the 6-Minute Walk Test in Late Pregnancy: An International Prospective Multicentre Study
BACKGROUND: Cardiac disease is the leading cause of maternal death. Assessment of cardiovascular fitness is important in pregnant women because it is linked to increased risk of cardiac disease but is rarely undertaken or studied. The 6-Minute Walk Test (6MWT) is a safe exercise test but is not used in pregnancy. We determined the 95% reference interval for resting heart rate (HR) and distance walked for the 6MWT, as well as hemodynamic recovery variables, and quantified expectations and actual experiences of exertion and breathlessness with exercise in late pregnancy. METHODS: After institutional research board approval (Australian and New Zealand Clinical Trials Registry Number: 12615000964516), 300 healthy term nulliparous pregnant women performed the 6MWT at 3 tertiary referral obstetric hospitals using a standardized protocol. Each woman underwent two 6MWT with maximum 15-minute recovery period after each test. Hemodynamic variables were measured at rest and after exercise. Participants were asked 4 questions, 2 regarding expectation and 2 regarding actual experience, using the Rating of Perceived Exertion scale and Modified Borg Dyspnea scale. RESULTS: Participant characteristics and resting variables were mean (standard deviation [SD]); age, 31 years (4.2 years); body mass index, 27 kg/m2 (2.9 kg/m2); gestational age, 37 weeks (1.3 weeks); HR, 85 bpm (10.8 bpm) with 95% reference interval 64–106 bpm; systolic blood pressure, 112 mm Hg (10.2 mm Hg); diastolic blood pressure, 72 mm Hg (8.6 mm Hg); oxygen saturation, 98% (0.9%); and respiratory rate, 18 breaths/min (5.7 breaths/min). The mean (SD) average distance walked was 488 m (94.9 m) with a speed of 3.0 mph (0.64 mph) with a 95% reference interval of 302–674 m. The mean (SD) HR increase with exercise was 12 bpm (11.0 bpm) with a median [quartile] recovery time of 5.0 minutes [1–8 minutes]. A lower resting HR was associated with increased distance walked (r = −0.207; 95% confidence interval, −0.313 to −0.096; P

Implementing a Pediatric Perioperative Surgical Home Integrated Care Coordination Pathway for Laryngeal Cleft Repair
BACKGROUND: The Pediatric Perioperative Surgical Home (PPSH) model is an integrative care model designed to provide better patient care and value by shifting focus from the patient encounter level to the overarching surgical episode of care. So far, no PPSH model has targeted a complex airway disorder. It was hypothesized that the development of a PPSH for laryngeal cleft repair would reduce the high rates of postoperative resource utilization observed in this population. METHODS: Institutional review board approval was obtained for the purpose of data collection and analysis. A multidisciplinary team of anesthesiologists, surgeons, nursing staff, information technology specialists, and finance administrators was gathered during the PPSH development phase. Standardized perioperative (preoperative, intraoperative, and postoperative) protocols were developed, with a focus on preoperative risk stratification. Patients presenting before surgery with ≥1 predefined medical comorbidity were triaged to the intensive care unit (ICU) postoperatively, while patients without severe systemic disease were triaged to a lower-acuity floor for overnight observation. The success of the PPSH protocol was defined by quality outcome and value measurements. RESULTS: The PPSH initiative included 120 patients, and the pre-PPSH period included 115 patients who underwent laryngeal cleft repair before implementation of the new process. Patients in the pre-PPSH period were reviewed and classified as ICU candidates or lower acuity floor candidates had they presented in the post-PPSH period. Among the 79 patients in the pre-PPSH period who were identified as candidates for the lower-acuity floor transfer, 70 patients (89%) were transferred to the ICU (P
