Abstract
Objective: To investigate the safety and therapeutic effect of split liver transplantation (SLT) in clinical application. Methods: This is a retrospective case-series study. The clinical data of 203 consecutive SLT, 79 living donor liver transplantation (LDLT) and 1 298 whole liver transplantation (WLT) performed at the Third Affiliated Hospital of Sun Yat-sen University from July 2014 to July 2023 were retrospectively analyzed. Two hundred and three SLT liver grafts were obtained from 109 donors. One hundred and twenty-seven grafts were generated by in vitro splitting and 76 grafts were generated by in vivo splitting. There were 90 adult recipients and 113 pediatric recipients. According to time, SLT patients were divided into two groups: the early SLT group (40 cases, from July 2014 to December 2017) and the mature SLT technology group (163 cases, from January 2018 to July 2023). The survival of each group was analyzed and the main factors affecting the survival rate of SLT were analyzed. The Kaplan-Meier method and Log-rank test were used for survival analysis. Results: The cumulative survival rates at 1-, 3-, and 5-year were 74.58%, 71.47%, and 71.47% in the early SLT group, and 88.03%, 87.23%, and 87.23% in the mature SLT group, respectively. Survival rates in the mature SLT group were significantly higher than those in the early SLT group (χ2=5.560,P=0.018). The cumulative survival rates at 1-, 3- and 5-year were 93.41%, 93.41%, 89.95% in the LDLT group and 87.38%, 81.98%, 77.04% in the WLT group, respectively. There was no significant difference among the mature SLT group, the LDLT group and the WLT group (χ2=4.016, P=0.134). Abdominal hemorrhage, infection, primary liver graft nonfunction,and portal vein thrombosis were the main causes of early postoperative death. Conclusion: SLT can achieve results comparable to those of WLT and LDLT in mature technology liver transplant centers, but it needs to go through a certain time learning curve.

Abstract
BACKGROUND Emergency room (ER) visits after surgery can be inconvenient and costly to the patient and the healthcare system. Estimates of the 30-day ER visit rate following ambulatory sinus procedures and their risk factors are largely unknown in the literature. OBJECTIVE To determine the 30-day postoperative ER visit rate following ambulatory sinus procedures and the causes and risk factors associated with ER visits. METHODS This is a retrospective, cohort study using data from the State Ambulatory Surgery and Services Databases (SASD) and the State Emergency Department Databases (SEDD) for California, New York, and Florida in 2019. We identified adult (18 years old) patients with chronic rhinosinusitis who underwent ambulatory sinus procedures from the SASD. Cases were linked to the SEDD to identify ER visits occurring within 30 days after the procedure. Logistic regression models were used to identify patient- and procedure-related risk factors associated with the 30-day postoperative ER visit. RESULTS Among the 23 239 patients, the 30-day postoperative ER visit rate was 3.9%. The most common reason for ER visit was bleeding (32.7%). A total of 56.9% of the ER visits occurred within the first week. In the multivariate analysis, factors associated with ER visits included Medicare (odds ratio [OR] 1.29 [1.09-1.52], P = .003), Medicaid (OR 2.06 [1.69-2.51], P < .001), self-pay/no insurance (OR 1.44 [1.03-2.00], P = .031), chronic kidney disease/end-stage renal disease (OR 1.63 [1.06-2.51], P = .027), chronic pain/opioid use (OR 2.70 [1.02-7.11], P = .045), and a disposition other than home (OR 12.61 [8.34-19.06], P < .001). CONCLUSION The most common reason for ER visit after ambulatory sinus procedures was bleeding. An increased ER visit rate was associated with certain demographic factors and medical comorbidities but not with procedure characteristics. This information can help us identify the patient populations who are at higher risk for ER visits to improve their postoperative recovery.

Abstract
Objective: To investigate the characteristics of initial ocular symptoms in children with optic pathway glioma (OPG) at different age stages. Methods: A retrospective case series study was conducted. Clinical data of 16 children with OPG who were diagnosed and treated in the Department of Ophthalmology, Beijing Children's Hospital, Capital Medical University from April 2017 to July 2021 were collected. The initial ocular symptoms, clinical manifestations of the eyes and nervous system, imaging and histopathological features were analyzed, and the differences in initial ocular symptoms between infants and young children aged≤36 months and older children aged>36 months were compared. Results: Of all 16 children included, 9 were male and 7 were female. The onset age was 15.0 (6.3, 56.5) months, and the diagnosis age was 48.0 (11.3, 78.0) months. There were 11 infants and young children, and 5 older children. Eye symptoms were the initial manifestation in 11 cases, including 8 cases of infants and young children (5 cases presented with irregular nystagmus, 2 cases with strabismus, and 1 case with failure to chase visual target), and 3 cases of older children (2 cases presented with decreased vision and 1 case with optic disc edema). The imaging findings showed that optic chiasm-involved OPG accounted for the highest proportion, with 3 cases in older children and 8 cases in infants and young children. Among the 8 children with optic chiasm-involved OPG who underwent surgical treatment, 5 were diagnosed with pilocytic astrocytoma according to histopathological results. Seven children had useful vision saved after treatment, and 1 child had visual loss accompanied by cognitive impairment due to surgery after 4 years of nystagmus. Conclusion: OPG in children often manifests as initial ocular symptoms, with irregular nystagmus being more common in infants and young children, and vision loss being the main symptom in older children.

Abstract
BACKGROUND AND PURPOSE Both dual-energy CT and quantitative susceptibility mapping can evaluate iron depositions in the brain. The purpose of this study was to compare these 2 techniques in evaluating brain iron depositions in Parkinson disease. MATERIALS AND METHODS Forty-one patients with Parkinson disease (Parkinson disease group) and 31 age- and sex-matched healthy controls (healthy control group) were included. All participants underwent brain dual-energy CT and quantitative susceptibility mapping. ROIs were set bilaterally in the globus pallidus, substantia nigra, red nucleus, caudate nucleus, and putamen. CT values and magnetic susceptibility values were obtained in each ROI. Differences in CT values and magnetic susceptibility values between the Parkinson disease and healthy control groups were compared, followed by analysis of receiver operating characteristic curves. Correlations between CT values and magnetic susceptibility values were then evaluated. RESULTS The CT values of the bilateral globus pallidus, substantia nigra, and red nucleus were higher in the Parkinson disease group (P < .05). The magnetic susceptibility values of the bilateral globus pallidus and substantia nigra were higher in the Parkinson disease group (P < .05). The CT value of the right globus pallidus in linear fusion images had the highest diagnostic performance (0.912). Magnetic susceptibility values of the bilateral globus pallidus in the Parkinson disease group were positively correlated with CT values at the level of 80 kV(peak), linear fusion images, and SN150 kV(p) (r = 0.466∼0.617; all, P < .05). CONCLUSIONS Both dual-energy CT and quantitative susceptibility mapping could assess excessive brain iron depositions in Parkinson disease, and we found a positive correlation between CT values and magnetic susceptibility values in the bilateral globus pallidus.

Abstract
Objective: To summarize the clinical and imaging features of linear scleroderma en coup de saber (LSCS) with central nervous system involvement in children. Methods: The clinical data(clinical manifestations and imaging features) of 6 children diagnosed with LSCS with central nervous system involvement who were admitted to Beijing Children's Hospital Affiliated to Capital Medical University from May 2019 to November 2021 were retrospectively analyzed. Results: The 6 patients were all female, aged 6.8 (3.3, 11.0) years at the time of diagnosis, and aged 3.0 (1.7, 4.1) years at the time of discovery of facial skin lesions. Facial skin lesions appeared before neurological symptoms in 5 cases, and neurological symptoms appeared 2 months before skin lesions in 1 case. All the patients had "sword wound" skin lesions on the forehead with alopecia. Neurological manifestations included epileptic seizures in 6 cases, focal neurological defects in 5 cases, and headaches in 2 cases. The intracranial lesions were all ipsilateral to the skin lesions. The magnetic resonance imaging (MRI) of 6 cases showed abnormal signals mainly involving white matter in 1 hemisphere, and 3 cases showed local encephalomalacia. The scattered low signal was observed in 5 cases on susceptibility weighted imaging. Localized brain parenchyma or leptomeninges enhancement was seen on Gadolinium-enhanced sequences in 5 cases. Scattered foci of calcification on the affected side were seen on cranial CT in 4 cases. Skin biopsy was performed in 2 cases. Part of the lesion of the brain was removed in 1 case, and the pathological findings suggested small vasculitis, which was consistent with skin pathological changes. All patients received symptomatic treatment with antiepileptic drugs. Oral prednisone combined with methotrexate was given in 4 cases, and 1 case was given oral prednisone only. One case was presumed to be in the resting stage of the disease due to significant cerebral atrophy in half of the brain, and only antiepileptic drugs were added. The patients were followed up for 6-36 months. The skin lesions of scleroderma and alopecia did not progress in 5 cases, and hemifacial atrophy was developed in 1 case, which was considered to be combined with Parry-Romberg syndrome. The seizures were controlled in 4 cases. One case had reduced seizure frequency but left hemiplegia. One patient still had intractable epilepsy and paroxysmal headache. Conclusions: LSCS with central nervous system involvement is more common in girls, with seizures and neurological defects as the main manifestations. Intracranial lesions are mostly ipsilateral to the skin lesions. Cerebral microbleeds, calcification, and encephalomalacia foci are common, and the pathological changes in skin and intracranial lesions are consistent with small-vessel vasculitis. Prednisone combined with methotrexate treatment has shown some efficacy, but some children remain with refractory epilepsy and neurological deficit symptoms.

Abstract
INTRODUCTION We aimed to assess the effect of Colonoscopy Skills Improvement (CSI) training on patient comfort and sedation-related complications during colonoscopy. METHODS This retrospective cohort study was performed on 19 endoscopists practicing in a Canadian tertiary care center who completed CSI training between October 2014 and May 2016. Data from 50 procedures immediately prior to, immediately after, and eight months following CSI training were included for each endoscopist. The primary outcome variable was intraprocedural comfort, and secondary outcomes included intraprocedural hypotension and hypoxia. Data were extracted from an electronic medical record and analyzed using SPSS version 20.0. Univariate analysis and stepwise multivariable logistic regression were performed to determine if there was an association between patient comfort and CSI training. Predictors of these outcomes including patient age, gender, sedation use and dosing, procedure completion, quality of bowel preparation, endoscopist experience, and specialty were included in the analysis. RESULTS 2533 colonoscopies were included in the study. The mean dose of sedatives was reduced immediately following CSI training and at 8 months for both Fentanyl (75.4 mcg v. 67.8 mcg v. 65.9 mcg, p < 0.001) and Midazolam (2.57 mg v. 2.27 mg v. 2.19 mg, p < 0.001). The percentage of patients deemed to have a comfortable exam improved following endoscopist participation in CSI training and remained improved at 8 months (55.1% v. 70.2% v. 69.8%, p < 0.001). No significant change in rates of intraprocedural hypoxia or hypotension were noted following CSI training. CONCLUSION CSI training is associated with improved patient comfort and reduced sedation requirements during colonoscopy.

Abstract
Objectives/Hypothesis Children have higher rates of asymptomatic SARS‐CoV‐2 infections or milder courses of infection, and their carrier status may potentially impact viral transmission to those providing them care. The aim of this study is to compare the existing COVID‐19 preoperative screening protocols to the detection of SARS‐CoV‐2 viral particles in surgical samples. Study Design Cross‐sectional study. Methods We conducted a prospective study with consecutive convenience sampling of children undergoing adenoidectomy between January and April 2021. Total nucleic acid was extracted from adenoid tissue and real‐time reverse transcription‐polymerase chain reaction was conducted to test for the presence of SARS‐CoV‐2 viral particles. Univariate logistic regression was used to summarize the effect size of variables of interest on the odds of having SARS‐CoV‐2 positive adenoid tissue. Results Forty adenoid samples were collected and 11 (27.5%) had a positive SARS‐CoV‐2 reverse transcriptase‐polymerase chain reaction. Patients with positive adenoids were older (11.8 vs. 7.9 years, odds ratio: 1.3, P = .01) and more likely to have had a positive nasopharyngeal swab in the previous 90 days (4/11 or 36% vs. 0). Conclusion These data are the first report on the presence of SARS‐CoV‐2 particles in pediatric adenoidectomy specimens, with a high percentage of patients showing evidence of viral particles within the adenoid. This finding calls in to question the utility of preoperative COVID screening protocols which have yet to be rigorously validated in asymptomatic patients and have the potential to delay patients' surgical care.

Abstract
1. The role of melanoma differentiation-associated protein 5 (MDA5) in infectious bursal disease virus (IBDV)-induced autophagy was studied in chicken embryos.2. Chicken embryo fibroblasts (CEF) were used as the research model and small interfering RNA (siRNA), western blot, indirect enzyme-linked immunosorbent assay (ELISA), real-time fluorescence quantitative polymerase chain reaction (PCR) and transmission electron microscopy were used to detect autophagy, IBDV replication, CEF damage, and activation of both MDA5 and its signalling pathway.3. The results showed that CEF infected with IBDV activated the intracellular MDA5 signalling pathway and caused autophagy via inactivation of the AKT/mTOR pathway. While autophagy promotes IBDV proliferation, MDA5 weakens IBDV-induced CEF autophagy thus inhibiting IBDV replication and protecting CEF cells.4. The results indicated that chMDA5 can be activated by IBDV and attenuate CEF autophagy caused by IBDV infection, thereby inhibiting IBDV replication. This study provided a foundation for further exploring the relationship between viruses, autophagy and the pathogenic mechanism of the MDA5 pathway involved in IBDV.

Abstract
OBJECTIVES Advanced practice providers (APPs), namely physician assistants (PAs) and nurse practitioners (NPs), play an increasing role in meeting growing demands for otolaryngologic services, particularly in rural communities. This study analyzes the geographic distribution of otolaryngology providers, which is essential to addressing future demands. STUDY DESIGN Cross-sectional study. SETTING Medicare Provider Utilization and Payment Data for 2017. METHODS Current Procedural Terminology codes were used to identify APPs providing 10 common otolaryngologic services. Geographic distribution was evaluated by calculating densities of APPs and otolaryngologists per 100,000 persons in urban versus rural counties as defined by the National Center for Health Statistics Urban-Rural Classification Scheme. RESULTS We identified cohorts of 8573 otolaryngologists, 1148 NPs, and 895 PAs. There were significantly higher population-controlled densities of otolaryngologists and APPs in urban counties as compared with rural counties. The majority of otolaryngologists (92.1%) and APPs (83.3%) were in urban counties. However, the proportion of APPs (16.7%) in rural counties was significantly higher than the proportion of otolaryngologists (7.9%) in rural counties (P < .01). A significant majority of rural counties (72.2%) had zero identified providers, and a greater proportion of rural counties (5.0%) were served exclusively by APPs as compared with urban counties (3.2%). CONCLUSIONS Although otolaryngologists and APPs mostly practiced in urban counties, a relatively higher proportion of APPs practiced in rural counties when compared with otolaryngology physicians. The majority of rural counties did not have any otolaryngologic providers. Given the expected shortages of otolaryngology physicians, APPs may play a critical role in addressing these gaps in access.

Abstract
OBJECTIVE Test a device that can improve upon the seal of filtering face mask respirators (FFRs). METHODS A 3-D prototype for a fit improvement frame (FIF) was created and quantitative fit testing was performed for FFRs with and without the FIF. RESULTS Thirty eight volunteers underwent fit testing. The overall fit pass rate was 100% for the 3M model 1860 masks, 50% for the 3M model 8511 masks, 13% for the BYD CARE model DE2322, and 7% for the Honeywell DC300N95. When using the FIF the overall passing rate increase to 87% for the DE2322 + FIF (P < 0.01) and for the DC300N95 + FIF the passing rate increase to 73% (P < 0.01). CONCLUSION The FIF is effective in improving the mask fit of a common flat fold N95 masks and potentially other N95 masks.

Abstract
Both hepatocellular carcinoma (HCC) and metabolic syndrome are closely associated with the composition of the gut microbiota (GM). Although it has been proposed that elements of the GM can be used as biomarkers for the early diagnosis of HCC, whether metabolic syndrome results in a misrepresentation of the results of the early diagnosis of HCC using GM remains unclear. We compared the differences in the faecal microbiota of 10 patients with primary HCC, six patients with type 2 diabetes mellitus (T2DM), seven patients with arterial hypertension, six patients with both HCC and T2DM, and 10 patients with both HCC and arterial hypertension, as well as 10 healthy subjects, using high-throughput sequencing of 16S rRNA gene amplicons. Our results revealed a significant difference in the GM between subjects with and without HCC. The 49 bacterial genera out of the 494 detected genera were significantly different between the groups. These results show that changes in the GM can be used to distinguish between subjects with and without HCC, and can resist interference of T2DM and arterial hypertension with the GM. The results of the present study provide an important basis for the clinical auxiliary diagnosis of HCC by detecting the GM.

Abstract
OBJECTIVE Cauterization prevents hemorrhage and optimizes the surgical field during endoscopic sinus surgery but may cause injury to nearby structures. The objective of this study is to examine thermal conductance from cauterization equipment across the skull base. STUDY DESIGN Cadaver and animal model. SETTING Surgical skills laboratory of an academic tertiary medical institution. METHODS A pilot study was conducted with a deidentified cadaver head and expanded to a goat head animal model. Endoscopic dissection was performed to expose the lamina papyracea, ethmoid roof, sphenoid roof, and frontal sinus. Cautery was applied to the frontal sinus of goat heads, and temperatures were measured via thermocouple sensors placed along the intracranial skull base. Surgical instruments studied included monopolar, bipolar, and endoscopic bipolar devices at various power settings. RESULTS Temperature increase, as averaged across all cautery powers and measurement positions, was highest for the monopolar cautery (17.55 °C) when compared with the bipolar and endoscopic bipolar devices (<2 °C for bipolar, Endo-Pen, Stammberger, and Wormald; P < .001). Monopolar cautery reached 30.86 °C at high power when averaged over all positions (P < .001) as compared with <3 °C for the other instruments. Temperatures rose as power of cautery was increased from low to medium and high. Temperatures decreased as the distance of the thermocouple sensor probe from the cautery origin increased. CONCLUSION Thermal conductance across the skull base varies depending on equipment and power of cautery, with monopolar resulting in the largest temperature increase. Choice and implementation of cauterization instruments have implications on inadvertent transmission of thermal energy during endoscopic sinus surgery.

Abstract
BACKGROUND AND PURPOSE Efficient detection of metastases is important for patient' treatment. This prospective study was to explore the clinical value of contrast-enhanced T2 FLAIR in imaging brain metastases using half-dose gadobenate dimeglumine. MATERIALS AND METHODS In vitro signal intensity of various gadolinium concentrations was explored by spin-echo T1-weighted imaging and T2 FLAIR. Then, 46 patients with lung cancer underwent nonenhanced T2 FLAIR before administration of half-dose gadobenate dimeglumine and 3 consecutive contrast-enhanced T2 FLAIR sequences followed by 1 spin-echo T1WI after administration of half-dose gadobenate dimeglumine. After an additional dose of 0.05 mmol/kg, 3D brain volume imaging was performed. All brain metastases were classified as follows: solid-enhancing, ≥ 5 mm (group A); ring-enhancing, ≥ 5 mm (group B); and lesion diameter of <5 mm (group C). The contrast ratio of the lesions on 3 consecutive phases of contrast-enhanced T2 FLAIR was measured, and the percentage increase of contrast-enhanced T2 FLAIR among the 3 groups was compared. RESULTS In vitro, the maximal signal intensity was achieved in T2 FLAIR at one-eighth to one-half of the contrast concentration needed for maximal signal intensity in T1WI. In vivo, the mean contrast ratio values of metastases on contrast-enhanced T2 FLAIR for the 3 consecutive phases ranged from 63.64% to 83.05%. The percentage increase (PI) values of contrast-enhanced T2 FLAIR were as follows: PIA < PIB (P = .001) and PIA < PIC (P < .001). The degree of enhancement of brain metastases on contrast-enhanced T2 FLAIR was lower than on 3D brain volume imaging (P < .001) in group A, and higher than on 3D brain volume imaging (P < .001) in group C. CONCLUSIONS Small or ring-enhancing metastases can be better visualized on delayed contrast-enhanced T2 FLAIR using a half-dose high-relaxivity contrast agent.

Abstract
1. This study explored the effects of Astragalus membranaceus polysaccharide (APS) on intestinal inflammatory damage of goslings infected with parvovirus ('gosling plague').2. A total of 90 healthy goslings were randomly divided into three groups; control, infected or APS treated, respectively. Goslings in the infection and APS treatment groups were inoculated with 0.3 ml allantoic fluid containing goose parvovirus (ELD50 = 1 × 103/0.3 ml) by intramuscular injection and the control group were injected with saline (0.3 ml) twice a day for 15 days.3. Blood serum and the jejunum were collected at 5, 10 and 15 days after the start of the experiment to detect the activities of SOD and GSH-Px, levels of MDA, sIgA, IL-1β, IL-6 and TNF-α, the mRNA expression of IL-1β, IL-6, LITAF, NF-κB, COX-2 and PGE2, pathological damage in the jejunum and serum IgG, IgM, C3, C4, IFN-γ levels.4. After APS treatment, SOD and GSH-Px activities increased, MDA content decreased; sIgA, IL-1β, IL-6 and TNF-α protein content, and IL-1β, IL-6, LITAF, NF-κB, COX-2 and PGE2 mRNA expression decreased in the jejunal tissue, serum IgG, IgM, C3, C4, IFN-γ significantly increased and pathological damage of jejunum significantly improved.5. In conclusion, APS reduced intestinal inflammatory damage in goslings infected with parvovirus by improving the immune and antioxidant functions of goslings.

Abstract
Objective Nurse practitioners and physician assistants form a growing advanced practice provider (APP) group. We aim to analyze the trends and types of services provided by APPs in otolaryngology. Study Design Cross-sectional study. Setting Medicare Provider Utilization and Payment Data: Physician and Other Supplier Public Use Files, 2012-2017. Methods The Medicare database was searched for 13 commonly used otolaryngology-specific Current Procedural Terminology ( CPT) codes, and 10 evaluation and management (E/M) codes were evaluated by provider type. Changes in code utilization were compared between physicians and APPs over time. Results From 2012 to 2017, there was a 51% increase in the number of otolaryngology APPs, compared to a 2.2% increase in physician providers. APPs increased their share of new and established patient visits from 4% to 7%d 11% to 15%, respectively. There was not a significant difference over time in number of patient visits performed annually per provider according to provider type. The increase in number of APP vs physician providers was significantly greater for every procedure except for balloon sinus dilation and tympanostomy tube placement. Conclusion Due to increasing numbers, APPs are accounting for more patient visits and procedures over time. The physician workforce and the numbers of procedures performed per physician have remained relatively stable from 2012 to 2017. Increasing complexity of patients seen and a broader range of procedures offered by work-experienced or postgraduate-trained APPs may further improve access to health care in the face of possible physician shortages.

Abstract
BACKGROUND There has been a rapid increase in electric motorized scooter (e-scooter) usage after the introduction of dockless, shareable devices. METHODS Case series from three tertiary hospitals in Los Angeles between May-September 2019. RESULTS Five patients had skull base fractures and CSF leaks or pneumocephalus after e-scooter accident, none wore helmets. Two patients were treated with observation alone, two patients were treated with lumbar drain or external ventriculostomy placement, and one patient died of their injuries prior to definitive management. CONCLUSION Without appropriate safety policies in place, the number of such injuries may increase as the use of e-scooters increase. Laryngoscope, 131:E1035-E1037, 2021.

Abstract
Resolving chemical species at the nanoscale is of paramount importance to many scientific and technological developments across a broad spectrum of disciplines. Hard x-rays with excellent penetration power and high chemical sensitivity are suitable for speciation of heterogeneous (thick) materials. Here, we report nanoscale chemical speciation by combining scanning nanoprobe and fluorescence-yield x-ray absorption near-edge structure (nano-XANES). First, the resolving power of nano-XANES was demonstrated by mapping Fe(0) and Fe(III) states of a reference sample composed of stainless steel and hematite nanoparticles with 50-nm scanning steps. Nano-XANES was then used to study the trace secondary phases in lithium iron phosphate (LFP) particles. We observed individual Fe-phosphide nanoparticles in pristine LFP, whereas partially (de)lithiated particles showed Fe-phosphide nanonetworks. These findings shed light on the contradictory reports on Fe-phosphide morphology in the literature. Nano-XANES bridges the capability gap of spectromicroscopy methods and provides exciting research opportunities across multiple disciplines.

Abstract
BACKGROUND Mast-cell activation syndrome (MCAS) is increasingly recognized. Sinonasal obstruction is common among these patients. There is a paucity of literature describing the characteristics of MCAS and treatment outcomes. METHODS Retrospective review of 192 patients with nasal congestion July 2017 to May 2019 among 3 providers (1 allergist, 2 rhinologists) was conducted. Suspected MCAS criteria were as follows: (1) at least 2 recurrent severe symptoms in addition to nasal congestion: flushing, pruritus, urticaria, angioedema, wheezing, throat swelling, headache, hypotension, diarrhea; (2) clinical response to medications that target mast cell mediators. Quality of life (QOL) outcomes were quantified using the 22-item Sino-Nasal Outcome Test (SNOT-22). RESULTS Thirty-two patients with nasal congestion were suspected of MCAS. The median age was 47 years; 24 of 32 were female; 13 of 32 had prior history of sinonasal surgery and 11 of 32 allergen immunotherapy. Out of 32, 19 had history of asthma, 10 drug allergy, 11 food allergy, and 10 anaphylaxis. The median number of medications targeting mast cell activation was 4 (range, 2-7). Eleven patients were offered surgery by a rhinologist after adequate medical management. Three of 32 patients showed elevation of serum tryptase. Fourteen completed pretreatment and posttreatment SNOT-22 (4/14 surgery, 10/14 medical management). Pretreatment score was 59.8 ± 6.2 (mean ± standard error [SEM]) and posttreatment score was 42.8 ± 6.7; the difference was statistically and clinically significant (p = 0.0015). Both groups showed a mean 17-point reduction. CONCLUSION A multidisciplinary approach to the treatment of sinonasal symptoms using both escalation of medical therapy and surgical approaches may improve QOL of patients with suspected MCAS. Consensus criteria for MCAS, which includes elevation in tryptase over baseline during an episode, may exclude the full spectrum of individuals with MCAS from potentially beneficial treatment.

Abstract
Biocomposites composed of Zeolitic Imidazolate Frameworks (ZIFs) are generating significant interest due to their facile synthesis, and capacity to protect proteins from harsh environments. Here we systematically varied the composition (i.e. relative amounts of ligand (2-methylimidazole), metal precursor (Zn(OAc)2·2H2O), and protein) and post synthetic treatments (i.e. washes with water or water/ethanol) to prepare a series of protein@ZIF biocomposites. These data were used to construct two ternary phase diagrams that showed the synthesis conditions employed gave rise to five different phases including, for the first time, biocomposites based on ZIF-CO3-1. We examined the influence of the different phases on two properties relevant to drug delivery applications: encapsulation efficiency and release profile. The encapsulation efficiencies of bovine serum albumin and insulin were phase dependent and ranged from 75% to 100%. In addition, release profiles showed that 100% protein release varied between 40 and 300 minutes depending on the phase. This study provides a detailed compositional map for the targeted preparation of ZIF-based biocomposites of specific phases and a tool for the straightforward analysis of the crystalline phases of ZIF based materials (web application named "ZIF phase analysis"). These data will facilitate the progress of ZIF bio-composites in the fields of biomedicine and biotechnology.

Abstract
BACKGROUND A bioabsorbable nasal valve implant (NVI) was introduced in 2016 as a minimally invasive solution to nasal valve collapse. Historically the introduction of less invasive procedures performable in-office has resulted in an increase in volume. Our objective is to evaluate this trend as it relates to nasal vestibular repair, and its impact on healthcare utilization. METHODS We interrogated the Medicare Part B national database for nasal vestibular repair (CPT code: 30465), Unlisted nasal procedure (30999) and septoplasty (30520) from 2010 to 2017. Septoplasty was used as a surrogate for overall nasal procedural rate. Linear regression modeling was used to examine the changes in reported vestibular repair rate adjusting for septoplasty rate. RESULTS In the Medicare population, the rate of septoplasty was stable from 2010 to 2017, increasing from 26,962 to 30,194 at an annual rate of 1.5%. Coding for unlisted nasal procedure increased from 272 to 333 at an adjusted annual rate of 1.1% over this time period. Coding for nasal vestibular repair increased from 2026 to 5331 over this interval at an adjusted annual rate of 0.9% from 2010 to 2016 but significantly increased to 5% between 2016 to 2017 (P < .0001). CONCLUSION The reported volume of nasal vestibular repair increased significantly in the year following Food and Drug Administration approval of NVIs. In the absence of a corresponding increase in septoplasty, this temporal relationship suggests that the introduction of NVIs impacted the utilization of this procedural code.

Abstract
OBJECTIVES To investigate the association between sensory impairment and all-cause mortality among the oldest-old (aged 80 and older) in China. DESIGN Prospective cohort study. SETTING Community-based setting in 22 provinces of China. PARTICIPANTS A total of 8788 older adults aged 80 and over at baseline with complete hearing and vision function data were included as the study population. MEASUREMENTS Sensory impairment was categorized as no sensory impairment, hearing impairment (HI) only, vision impairment (VI) only and dual sensory impairment (DSI) according to hearing and vision function. Deaths were identified through interviews by close family members. Cox proportion hazards regression models were used to examine the association of sensory impairment with mortality, adjusting for socio-demographic data, life style factors and health status. RESULTS The mean age was 92.3 ± 7.6 years old, and 60.1% of participants were female. Among 8788 participants, 9.8% were recognized as DSI, 9.7% were HI only and 10.4% with VI only. Comparing with participants with no sensory impairment, those with VI only (HR=1.10, 95% CI=1.01-1.20) and DSI (HR=1.21, 95% CI=1.09-1.35) were significantly associated with higher risk of all-cause mortality in the fully adjusted model. CONCLUSION Our results demonstrated that VI only and DSI were significantly associated with higher risk of mortality among Chinese older adults aged 80 and over. The finding advocated that it is necessary to identify and manage sensory impairments for the advanced ages to reduce mortality risks.

Abstract
OBJECTIVES To estimate the prevalence of sarcopenia in different ethnic groups and the association with cultural life styles in west China. DESIGN A cross-sectional study. SETTINGS The communities in Yunnan, Guizhou, Sichuan, and Xinjiang provinces. PARTICIPANTS 4500 participants aged 50 years or older in west China were enrolled in this study. Sarcopenia was defined according to the diagnostic algorithm of the Asia Working Group for Sarcopenia (AWGS). MEASUREMENTS We measured gait speed, handgrip strength and muscle mass by using bioelectrical impedance analysis (BIA) for all eligible participants. Life-style information were collected by reviewers. Relationships between sarcopenia and ethnic groups were analyzed using univariate and multivariate analyses. RESULTS We found 869 (19.31%) adults aged 50 years old or older were sarcopenia. The mean age is 62.4±8.3 years. The main ethnic groups enrolled in this study is Han, Tibetan, Qiang, Yi and Hui. The crude prevalence of sarcopenia is 22.3% in Han, 18.2% in Tibetan, 11.8% in Qiang, 34.7% in Yi and 26.7% in Hui. Compared to Han, after adjusting sex and age, Qiang has a lower prevalence of sarcopenia (odds ratio [OR]: 0.44, 95% CI 0.35-0.55), Yi has a higher prevalence of sarcopenia (OR: 1.78, 95% CI 1.29-2.43). While adding adjusting other potential cofounders, sarcopenia is still less prevalent in Qiang (OR: 0.44, 95% CI 0.34-0.57). CONCLUSIONS The crude prevalence of sarcopenia is 22.3% in Han, 18.2% in Tibetan, 11.8% in Qiang, 34.7% in Yi and 26.7% in Hui. Sarcopenia was less prevalent in Qiang compared with Han. Further studies to determine related factors of sarcopenia among different ethnic groups are recommended.

Abstract
OBJECTIVE Frailty and poor oral health are both common age-related conditions. However, the association between oral health and frailty has not been explored thoroughly among older Chinese adults. We aimed to investigate the associations between number of teeth, denture use, and frailty among older adults in western China. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS Participants were 4037 community-dwelling individuals aged 60 and older from the West China Health and Aging Trend (WCHAT) study. MEASUREMENTS Frailty was assessed using the physical frailty phenotype (PFP) and categorized as non-frail, prefrail and frail. In addition, number of teeth and denture use were examined by calibrated dentists. Multinomial logistic regression models were performed to examine the association between number of teeth, denture use, and frailty. RESULTS The overall prevalence of frailty was 6.7% among 4037 participants aged 60 and older in western China. Participants with no more than 20 teeth were associated with higher odds of being prefrail or frail whether wearing dentures or not. Denture using could not help lower the odds of being prefrail or frail for older adults with fewer teeth. CONCLUSIONS This study suggested that frailty was associated with having fewer teeth (≤20 teeth) among older Chinese adults. Future research involving targeted interventions addressing number of teeth may help provide information to establish effective strategies for frailty prevention in older adults.

Abstract
OBJECTIVE To identify the prevalence, lifestyle factors, chronic disease status, and assessing the metabolic profile, comparing key differences in a cohort of subjects with non-sarcopenia/non-obesity (H), sarcopenia/non-obesity (S), non-sarcopenia/obesity (O) and sarcopenia obesity (SO) in a multi-ethnic population in west China. DESIGN A cross-sectional study. SETTING The communities in Yunnan, Guizhou, Sichuan, and Xinjiang provinces. PARTICIPANTS We included 4,500 participants aged 50 years or older who did bioelectrical impedance in our analysis from West China Health and Aging Trend (WCHAT) study. MEASUREMENTS We measured gait speed, handgrip strength and muscle mass by using bioelectrical impedance analysis (BIA) for all participants. We defined sarcopenia using the diagnostic algorithm recommended by the Asian Working Group for Sarcopenia (AWGS). Obesity was defined as the highest sex-specific quintile of the percentage body fat. Different variables like anthropometry measures, life styles, chronic disease and blood test were collected. Analysis of variance and a multinomial logistic regression analysis adjusting for covariates were used to assess the differences of metabolic profiles among different groups. RESULTS Of 4500 participants aged 50 years old or older, the proportions of H, O, S, SO were 63.0%, 17.7%, 16.7% and 2.6%, respectively. And the prevalence of S subjects in men was 18.3% and 15.7% in women, while the prevalence of SO was 3.7% in men and 2.0% in women. Data showed that the prevalence of S and SO has an aging increase pattern which was opposite with O. Both S and SO tends to be older, lower educational level, without spouse, smoking, comorbidity of chronic disease, poor nutrition status, depression and cognitive decline compared to H and S seems to be worse than SO. Compared to H, S cohort showed a decrease in Vitamin D, triglyceride, albumin, fasting glucose, insulin, creatinine, ALT, nutrition scores and increase in HDL. SO cohort were observed for an increase in cholesterol, LDL, total protein and decrease in vitamin D. While O cohort showed an increase in triglyceride, cholesterol, LDL, total protein, glucose, insulin, WBC, uric acid, ALT and nutrition scores, but a decrease in HDL and vitamin D level. CONCLUSIONS Among individuals aged 50 years old or older in West China. S, O and SO participants demonstrate distinct differences in the life-styles, chronic disease profile, and metabolic profiles. The prevalence of S and SO has an aging increase pattern contrary to O. Both S and SO tend to be older, lower educational level, without spouse, smoking, comorbidity of chronic disease, poor nutrition status, depression and cognitive decline compared to H and S looks like to be worse than SO. Besides, the S subjects seem to have more metabolic index changes than SO compared to H. While O subjects have some contrary metabolic index to S subjects.

Abstract
OBJECTIVES Previous literature has reported that physical frailty (PF) closely associated with cognitive impairment (CI). In this study, we aim to describe and evaluate the prevalence and associated factors with different patterns of PF and cognitive impairment. DESIGN A cross-sectional study. SETTING AND PARTICIPANTS Community-dwelling older adults aged ≥60 from the West China Health and Aging Trend (WCHAT) study were included in this study. MEASUREMENTS Participants were assessed the PF and cognitive impairment. PF was assessed using the physical phenotype as defined by Fried's criteria. Cognitive impairment was identified using the Short Portable Mental Status Questionnaire (SPMSQ). According different patterns of PF and cognitive impairment, participants were divided into 4 groups: not-PF and cognitive intact ( "neither" group), not-PF and cognitive impairment ("CI only" group), PF and cognitive intact ("PF only" group), and PF and cognitive impairment ("both" group). Multinomial logistic regression was used to explore the association between medical conditions and different patterns of PF and cognitive impairment after adjusting the demographic characteristics. RESULTS Among 4,103 participants (age 67.8 + 5.9 years, female 58.3%), 78.8%, 3.9%, 14.5% and 2.9% were "neither", "PF only", "CI only", and "both", respectively. The prevalence of "PF only", "CI only" and "both" were associated with age, lower education level and single status. In addition, there was substantial ethnicity heterogeneity in the prevalence of different patterns of PF and cognitive impairment. Comparing with "neither", PF and/or cognitive impairment had higher association with depression, ADLs impairment, and malnutrition. Of note, obesity was only significantly associated with "PF only", but not associated with "CI only" or "both". CONCLUSIONS We found the substantial demographic and medical conditions disparities in different patterns of PF and cognitive impairment. Further research should focus on the efficient and practical screen to predict the risk of "PF only", "CI only" and "both".

Abstract
OBJECTIVE Delayed medical care may be costly and dangerous. Examining referral pathways may provide insight into ways to reduce delays in care. We sought to compare time between initial referral and first clinic visit and referral and surgical intervention for index otolaryngologic procedures between a public safety net hospital (PSNH) and tertiary-care academic center (TAC). METHODS Retrospective cohort study of eligible adult patients undergoing one of several general otolaryngologic procedures at a PSNH (n = 216) and a TAC (n = 161) over a 2-year time period. RESULTS PSNH patients were younger, less likely to have comorbidities and more likely to be female, Hispanic or Asian, and to lack insurance. Time between referral and first clinic visit was shorter at the PSNH than the TAC (Mean 35.8 ± 47.7 vs 48.3 ± 60.3 days; P = .03). Time between referral and surgical intervention did not differ between groups (129 ± 90 for PSNH vs 141 ± 130 days for TAC, P = .30). On multivariate analysis, the TAC had more patient-related delays in care than the PSNH (OR: 3.75, P < .001). Time from referral to surgery at a PSNH was associated with age, source of referral, type of surgery, diagnostic workup and comorbidities, and at a TAC was associated with gender and type of surgery and comorbidities. CONCLUSIONS Sociodemographic differences between PSNH and TAC patients, as well as differences in referral pathways between the types of institutions, influence progression of surgical care in otolaryngology. These differences may be targets for interventions to streamline care. LEVEL OF EVIDENCE 2c.

Abstract
Objective Balloon sinuplasty utilization has increased significantly since its introduction over a decade ago. However, the most common associated complications are still unknown. The objective of this study was to analyze adverse events related to balloon sinuplasty. Study Design Retrospective cross-sectional analysis. Setting Food and Drug Administration’s MAUDE database (Manufacturer and User Facility Device Experience; 2008-2018). Subjects and Methods The MAUDE database was searched for all reports on adverse events involving balloon sinuplasty devices from the 3 leading manufacturers: Acclarent, Entellus, and Medtronic. Reported events were reviewed and categorized. Results During the study period, there were 211 adverse events from 208 reports divided into the following categories: patient related (n = 102, 48.3%), device related (n = 101, 47.9%), and packaging related (n = 8, 3.8%). Four periprocedural deaths were reported but were not clearly associated with technical complications. The most common device-related complications were guide catheter malfunction (39.6%), balloon malfunction (38.6%), and imprecise navigation (17.8%). The most common patient-related complications were cerebrospinal fluid leak (36.3%), eye swelling (29.4%), and epistaxis (11.8%). A lateral canthotomy was performed in 30.0% of eye-swelling complications. Sixty percent of eye complications occurred during balloon dilation of the maxillary sinus. The years 2014 (n = 48) and 2012 (n = 32) had the highest number of adverse events reported as compared with all other years. Conclusion The most common adverse events associated with balloon sinuplasty include balloon malfunction, guide catheter malfunction, cerebrospinal fluid leak, and significant eye swelling. Health care providers should discuss these possible complications when consenting patients for balloon sinuplasty.

Abstract
Sphingomyelin phosphodiesterase acid-like 3b (SMPDL3b) is a lipid raft enzyme that regulates plasma membrane (PM) fluidity. Here we report that SMPDL3b excess, as observed in podocytes in diabetic kidney disease (DKD), impairs insulin receptor isoform B-dependent pro-survival insulin signaling by interfering with insulin receptor isoforms binding to caveolin-1 in the PM. SMPDL3b excess affects the production of active sphingolipids resulting in decreased ceramide-1-phosphate (C1P) content as observed in human podocytes in vitro and in kidney cortexes of diabetic db/db mice in vivo. Podocyte-specific Smpdl3b deficiency in db/db mice is sufficient to restore kidney cortex C1P content and to protect from DKD. Exogenous administration of C1P restores IR signaling in vitro and prevents established DKD progression in vivo. Taken together, we identify SMPDL3b as a modulator of insulin signaling and demonstrate that supplementation with exogenous C1P may represent a lipid therapeutic strategy to treat diabetic complications such as DKD.

Abstract
Objective: To analyze the treatment results of cardiac rupture in patients with acute myocardial infarction (AMI) . Method: Clinical data of 6 with cardiac rupture after AMI, who were hospitalized in our hospital from June 2015 to June 2017, were retrospectively analyzed,and the clinical manifestations, methods of treatment and outcomes were investigated. Results: Cardiac function classification was Killip class Ⅱin all patients. There were 3 massive anterior wall myocardial infarction, 2 anterior wall myocardial infarction,and 1 inferior myocardial infarction. There were 4 patients with ventricular septal defect, 1 patient with rupture of papillary muscle,and 1 patient with left ventricular free wall rupture.All patients received continuous infusion of vasoactive medicines and treated with intra-aortic balloon pump(IABP), 2 patients (1 patient accepted operative treatment,and 1 patient received conservative treatment) were treated with extracorporeal membrane oxygenation (ECMO), mechanical ventilation,and continuous renal replacement therapy(CRRT).Three patients received surgical repair,1 case was supported by IABP, 1 case supported by ECMO,CRRT,and IABP,and 1 case did not use IABP or ECMO post operation. All 3 surgically treated patients recovered successfully and were discharged from hospital.Meanwhile, in the other 3 patients treated conservatively, 2 patients died in the hospital and 1 patient was discharged according to own will. Conclusion: On the basis of vasoactive medicines and IABP, surgery repair is a feasible option for cardiac rupture patients secondary to AMI,and ECMO may improve the perioperative state in these patients.

Abstract
Objective: To investigate the clinical features and diagnostic bases of childhood leukoencephalopathy with cerebral calcifications and cysts (LCC). Methods: The clinical data involving manifestations and laboratory examinations of 4 children with LCC admitted to Beijing Children's Hospital Affiliated to Capital Medical University from 2012 to 2017 were retrospectively summarized. Each patient had a follow-up visit ranging from 4 months to 5 years and 9 months after initial examination. Results: Patients consisted of 2 males and 2 females, whose age of onset was respectively 2 years and 9 months, 6 years and 2 months, 7 years and 10 months, and 5 years and 1 month. The main clinical symptoms of these cases included headache, dizziness, partial seizure and claudication, and two of these cases had insidious onset. Cerebral calcifications and cysts with leukoencephalopathy were detected by neuroimaging in all patients. In addition, multifocal microhemorrhages and calcifications were observed by magnetic susceptibility-weighted imaging (SWI) series in 3 patients. Brain biopsy performed on 1 case disclosed a neuronal reduction in the cerebral cortex, loosening of focal white matter, multifocal lymphocyte infiltration, fresh hemorrhages, and gliosis, as well as angiomatous changes of blood vessels with hyalinized thicken-wall, stenotic or occlusive lumina and calcification deposits. The compound heterozygous mutations of n.*10G>A and n.82A>G in SNORD118 were identified in 1 case by target-capture next-generation sequencing. Sanger sequencing verified that the variant n.*10G>A was a novel mutation and it was of paternal-origin, while the variant n.82A>G was of maternal-origin, which had already been reported to be pathogenic to LCC. Follow-up study had shown continued partial seizure in 1 case and remissive claudication in another, while the remaining 2 cases had a relatively favorable outcome without obvious neurological symptoms at present time. Conclusions: The clinical manifestations of LCC are nonspecific, and the onset of the disease tends to be insidious. The triad neuroimaging findings of cerebral calcifications, cysts and leukoencephalopathy are essential to the diagnosis of the disease, and the signals of microhemorrhages revealed by SWI series provide another eloquent reference for the diagnosis. As biopsy is invasive and usually unavailable in the early stage, gene assessment, instead of pathological data, should be the gold standard in the diagnosis of LCC.

Abstract
AIM To investigate the efficiency of absolute cerebral blood volume (CBV) in the differentiation of tumour recurrence (TR) and radionecrosis (RN) in brain metastases (BM) and to evaluate the performance of absolute CBV compared to relative CBV (rCBV). MATERIALS AND METHODS Between March 2015 and June 2017, 46 patients with BM underwent quantitative dynamic susceptibility contrast perfusion-weighted imaging (DSC-PWI) because new enhancement had been demonstrated in irradiated lesions after gamma knife radiotherapy. The patients were assigned to either the TR group or RN group on the basis of MR perfusion follow-up or histopathological outcome. Absolute CBV of lesions (CBVlesion) and contralateral normal appearing white matter (CBVNAWM) in both groups were obtained. Mean rCBV were calculated as CBVlesion/CBVNAWM, which was equal to rCBV using traditional DSC-PWI. RESULTS CBVlesion of TR alone was significantly higher than the other parameters in both groups (p<0.001, separately). CBVlesion had smaller interobserver difference than CBVNAWM and rCBV (p<0.001, separately). Although CBVlesion significantly correlated with rCBV (r=0.914, p<0.001) and both had a similar specificity (96%) in differential diagnosis, CBVlesion had a higher sensitivity (96.9% versus 90.9%) to predict the treatment outcome. The best cut-off value of CBVlesion was 21.8 ml/100 g. CONCLUSION Quantitative DSC-PWI is a powerful method for the assessment of radiosurgically treated brain metastases. Absolute CBV has higher diagnostic efficiency than rCBV, which enables an absolute quantification of the regional CBV and prediction of tumour response. These advantages promote the intra- and inter-patient quantitative image comparison across different institutions.

Abstract
To our knowledge, no comprehensive meta-analysis has examined the association between sarcopenia and the risk of fractures. This systematic review and meta-analysis of prospective cohort studies aims to summarize whether sarcopenia is a risk factor for fractures among community-dwelling older adults. We searched four electronic literature databases (Ovid MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, PubMed) for relevant publications from inception to December 2017, using relevant keywords. We conducted a pooled analysis of the association between sarcopenia and the risk of fractures by employing a random-effects model. Subgroup analyses were conducted based on definitions of sarcopenia and gender. In total, nine studies were included in our systematic review and meta-analysis. The prevalence of sarcopenia ranged from 4.3 to 33.1%. The pooled RR of fractures for the sarcopenic versus the nonsarcopenic was 1.34 (95% CI = 1.13-1.58, P = 0.001, I2 = 5.5%, P-heterogeneity = 0.391). Subgroup analyses showed that associations between sarcopenia and fractures were significant when using the AWGS definition (combined effect size = 1.78, 95% CI = 1.25-2.54, P = 0.001), and studies in males (combined effect size = 1.39, 95% CI = 1.13-1.71, P = 0.002). In conclusion, we found that compared to nonsarcopenic, the association between sarcopenia and fractures among community-dwelling older people was significant when using the AWGS definition, and only for males. Future studies are needed to establish a possible association between sarcopenia definitions and risk of fractures of different sites.
