Abstract
INTRODUCTION Surgeons are at high risk of developing musculoskeletal symptoms due to a range of factors including, maladaptive positioning and surgical ergonomics. Cervical muscle strain and biomechanical load is most prevalent due to repetitive motions and prolonged static neck positioning. This issue is apparent through reports of prevalence between 10 and 74.4% among surgeons. The aim of this systematic review is to provide an objective assessment of the clinical evidence available and a descriptive analysis of the effects of kinematics and surgical ergonomics on the prevalence of surgeons' cervical musculoskeletal pain. METHODS This is PRISMA-compliant systematic review of clinical studies assessing the prevalence of cervical musculoskeletal dysfunction in surgeons by searching PUBMED and Ovid EMBASE databases from inception to 19th October 2023. Study quality was graded according to the National Institutes of Health study quality assessment tools. RESULTS A total of 9 studies were included in the final qualitative analysis. The use of loupes, open surgery and excessive neck flexion (>30°) were associated with cervical dysfunction. Comparison of study outcomes was challenging due to heterogeneity within study methods and the paucity of methodological quality. CONCLUSION The current literature assessing ergonomic and biomechanical factors predisposing surgeons to cervical musculoskeletal dysfunction is insufficient to provide reliable guidance for clinicians. Although the literature identifies factors contributing to work-related cervical dysfunction, few attempt to evaluate interventions for improved surgical ergonomics. An objective assessment of interventions that prompt postural correction with the aim to improve neck pain in surgeon cohorts is warranted.

Abstract
The multi-component glass system has a composition of 10K2O-10ZnO-55 B2O3-(25-x)V2O5-xBi2O3 (x = 4, 5, 7.5, 9, 10 mol%) are synthesized by the melt-quenching method. Using X-ray diffraction examination, the amorphous phase in the material was confirmed. The physical characteristics of the produced compositions are examined using density (D) and molar volume (Vm). Calculations of physical properties showed that adding Bi2O3 from 4 to 10 mol% increased the glass density from 2.7878 to 3.3617 g cm-3 and decreased the molar volume from 40.4196 to 38.5895 cm3/mol. Studies of glass samples using the FTIR show bands of absorption for oxides in different structural groups. Octahedral [ BiO 6 ], [ BO 4 ], and tetrahedral [ BO 3 ] structural units are observed in the present glass matrices. The cutoff wavelength ( λ C ), and optical band gap energy were determined using UV absorption spectra. The increase in non-bridging oxygens can be linked to the decrease in optical band gap energy ( E opt ) (direct and indirect) and the increase in cutoff wavelength with an increase in Bi2O3 content. This is attributed to the existence of bismuth ions and the creation of non-bridging oxygens. Besides that, the values of optical parameters, viz., optical electronegativity, refractive index, and molar refractivity, are calculated. The metallization criterion values are less than 1 and the glass samples exhibit an increased tendency towards metallization. Both the conductivity and the dielectric constant increase with the rise in Bi2O3 content, however, the dielectric loss and the impedance reduce. The behavior and values of conductivity for the studied glasses reveal the semiconducting properties of all glass samples. These results suggest that the produced glass samples may be employed as amorphous semiconductors in electronics and memory switching devices.

Abstract
Introduction To describe the duration of survival among bone tumour patients with endoprosthesis reconstruction and to determine frequency of implant failure, revision of surgery, and amputation after endoprosthesis reconstruction. Materials and methods A retrospective cross-sectional review of all patients with either primary bone tumour or secondary bone metastases treated with en bloc resection and endoprosthesis reconstruction from January 2008 to December 2020. Results A total of 35 failures were recorded among the 27 (48.2%) patients with endoprostheses. Some of the patients suffered from one to three types of modes of failure on different timelines during the course of the disease. Up to eight patients suffered from more than one type of failure throughout the course of the disease. Out of all modes of failure, local recurrence (type 5 failure) was the most common, accounting for 25.0% of all failure cases. Four patients (7.1%) eventually underwent amputation, which were either due to infection (2 patients) or disease progression causing local recurrence (2 patients). Conclusion The overall result of endoprosthesis reconstruction performed in our centre was compatible with other centres around the world. Moreover, limb salvage surgery should be performed carefully in a selected patient group to maximise the benefits of surgery.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
PURPOSE/OBJECTIVE(S) ART is a standard treatment used to reduce the risk of metastasis and recurrence in moderate‒to‒high-risk cSCC patients. Indications for ART have been largely based on pathologic risk factors and informed by staging systems, and while radiation oncologists generally designate a >10% risk threshold for usage of ART, there is no consensus on which groups of tumors may benefit from ART. The 40-GEP test has been independently validated to predict a cSCC patient's risk for regional/distant metastasis in patients with one or more high-risk clinicopathologic factors and reports three biologic risk groups: Class 1 (low, ∼7%), Class 2A (moderate, 20-25%), and Class 2B (high risk, >50%) for metastasis. This study aims to evaluate whether a biomarker informed risk stratification approach using a 40-GEP result could refine the ability to select patients with node negative cSCC at higher risk of metastasis who are most likely to benefit from ART. MATERIALS/METHODS In this retrospective study, all patients had primary cSCC tissue with verified clinicopathologic information of tumors with one or more high-risk factors, met clinical testing criteria, were comprehensively staged, and had outcomes data (n = 954). Patients with node positive disease, or those with nodal failure within 3 months of diagnosis were excluded (n = 19). From the n = 935, an intermediate risk population wherein ART is often considered was defined as Brigham and Women's Hospital (BWH) ≥T2a (n = 489). Kaplan-Meier survival analysis and log-rank test were used to assess metastasis free survival (MFS). Univariate Cox regression compared metastasis rates between 40-GEP results. RESULTS The 3-year MFS rate for this eligible for ART cohort was 82.4% The 40-GEP demonstrated statistically significant risk stratification with MFS rates of 92.4%, 76.1% and 59.4% for Class 1, Class 2A and Class 2B, respectively (p<0.0001). Cox regression was significant for Class 2A and 2B compared to Class 1, with a 3.2-fold and 6.4-fold increase in metastasis, respectively (p<0.0001). 64% (59/92) of all metastases received a Class 2A result, and 44% (14/32) of Class 2B patients metastasized. 46% (223/489) of the cohort received a Class 1 result. Of patients staged BWH T1 (n = 446), those with a Class 2A and 2B had an 88.7% and 66.7% MFS rate, respectively. CONCLUSION Within this eligible for ART population, patients with Class 2A or 2B 40-GEP results have inferior rates of MFS, while Class 1 patients have <10% risk of metastasis. Nearly half of this population received a 40-GEP Class 1 result and could be considered for treatment de-intensification trials. Conversely, patients with low-risk BWH T1 stage, who are traditionally not considered for ART, that received a Class 2A or 2B (>10% risk of metastasis) could be considered for adjuvant therapy.

Abstract
BACKGROUND Few studies have examined online experience by young people who die by suicide. METHODS A 3-year UK-wide consecutive case series of all young people aged 10-19 who died by suicide, based on national mortality data. We extracted information on the antecedents of suicide of 544 of these 595 deaths (91%) from official investigations, mainly inquests. RESULTS Suicide-related online experience was reported in 24% (n = 128/544) of suicide deaths in young people between 2014 and 2016, equivalent to 43 deaths per year, and was more common in girls than boys (OR 1.87, 95% CI 1.23-2.85, p = 0.003) and those identifying as LGBT (OR 2.35, 95% CI 1.10-5.05, p = 0.028). Searching for information about method was most common (n = 68, 13%), followed by posting suicidal ideas online (n = 57, 10%). Self-harm, bereavement (especially by suicide), social isolation, and mental and physical ill-health were more likely in those known to have suicide-related online experience compared to those who did not. 29 (5%) were bullied online, more often girls (OR 2.84, 1.34-6.04, p = 0.007). Online bullying often accompanied face-to-face bullying (n = 16/29, 67%). CONCLUSIONS Suicide-related online experience is a common, but likely underestimated, antecedent to suicide in young people. Although its causal role is unclear, it may influence suicidality in this population. Mental health professionals should be aware that suicide-related online experience - not limited to social media - is a potential risk for young patients, and may be linked to experiences offline. For public health, wider action is required on internet regulation and support for children and their families.

Abstract
BACKGROUND Mammalian lungs comprise a complex microbial ecosystem that interacts with host physiology. Previous research demonstrates that the environment significantly contributes to bacterial community structure in the upper and lower respiratory tract. However, the influence of host genetics on the makeup of lung microbiota remains ambiguous, largely due to technical difficulties related to sampling, as well as challenges inherent to investigating low biomass communities. Thus, innovative approaches are warranted to clarify host-microbe interactions in the mammalian lung. RESULTS Here, we aimed to characterize host genomic regions associated with lung bacterial traits in an advanced intercross mouse line (AIL). By performing quantitative microbial profiling (QMP) using the highly precise method of droplet digital PCR (ddPCR), we refined 16S rRNA gene amplicon-based traits to identify and map candidate lung-resident taxa using a QTL mapping approach. In addition, the two abundant core taxa Lactobacillus and Pelomonas were chosen for independent microbial phenotyping using genus-specific primers. In total, this revealed seven significant loci involving eight bacterial traits. The narrow confidence intervals afforded by the AIL population allowed us to identify several promising candidate genes related to immune and inflammatory responses, cell apoptosis, DNA repair, and lung functioning and disease susceptibility. Interestingly, one genomic region associated with Lactobacillus abundance contains the well-known anti-inflammatory cytokine Il10, which we confirmed through the analysis of Il10 knockout mice. CONCLUSIONS Our study provides the first evidence for a role of host genetic variation contributing to variation in the lung microbiota. This was in large part made possible through the careful curation of 16S rRNA gene amplicon data and the incorporation of a QMP-based methods. This approach to evaluating the low biomass lung environment opens new avenues for advancing lung microbiome research using animal models.

Abstract
This study compares the effectiveness of pharmacological treatments to develop guidelines for the management of acute pain after tooth extraction. We searched Medline, EMBASE, CENTRAL, and US Clinical Trials registry on November 21, 2020. We included randomized clinical trials (RCTs) of participants undergoing dental extractions comparing 10 interventions, including acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and combinations to placebo. After duplicate screening and data abstraction, we conducted a frequentist network meta-analysis for each outcome at 6 h (i.e., pain relief, total pain relief [TOTPAR], summed pain intensity difference [SPID], global efficacy rating, rescue analgesia, and adverse effects). We assessed the risk of bias using a modified Cochrane RoB 2.0 tool and the certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation approach. We implemented the analyses in RStudio version 3.5.3 and classified interventions from most to least beneficial or harmful. We included 82 RCTs. Fifty-six RCTs enrolling 9,095 participants found moderate- and high-certainty evidence that ibuprofen 200 to 400 mg plus acetaminophen 500 to 1,000 mg (mean difference compared to placebo [MDp], 1.68; 95% confidence interval [CI], 1.06-2.31), acetaminophen 650 mg plus oxycodone 10 mg (MDp, 1.19; 95% CI, 0.85-1.54), ibuprofen 400 mg (MDp, 1.31; 95% CI, 1.17-1.45), and naproxen 400-440 mg (MDp, 1.44; 95% CI, 1.07-1.80) were most effective for pain relief on a 0 to 4 scale. Oxycodone 5 mg, codeine 60 mg, and tramadol 37.5 mg plus acetaminophen 325 mg were no better than placebo. The results for TOTPAR, SPID, global efficacy rating, and rescue analgesia were similar. Based on low- and very low-certainty evidence, most interventions were classified as no more harmful than placebo for most adverse effects. Based on moderate- and high-certainty evidence, NSAIDs with or without acetaminophen result in better pain-related outcomes than opioids with or without acetaminophen (except acetaminophen 650 mg plus oxycodone 10 mg) or placebo.

Abstract
This study explored the potential genes and economic factors that might be associated with growth and heat tolerance in two sheep breeds. Data on growth performance from the third month to six months of age were obtained based on records. In comparison to Aboudeleik lambs, Barki lambs developed considerably greater starting body weight, final body weight, final body weight gain, daily weight gain, and percentage increase in BW/month. Single nucleotide polymorphisms (SNPs) were found between lambs of the two breeds using PCR-DNA sequencing of CAST, LEP, MYLK4, MEF2B, STAT5A, TRPV1, HSP90AB1, HSPB6, HSF1, ST1P1, and ATP1A1 genes. Lambs from each breed were divided into groups based on detected SNPs in genes related to growth. The least squares means of the differentiated groups revealed a significant correlation of detected SNPs with growth and heat tolerance attributes (p ≤ 0.05). Barki lambs elicited greater total variable costs, total costs, total return, and net return values. The Barki sheep provided the best economic efficiency value when comparing the percentage difference between net profit and economic efficiency. Together with economic considerations, SNPs found may be used as proxies for marker-assisted selection of the best breed of sheep for traits related to growth and heat tolerance.

Abstract
Monkeypox virus, now known as Mpox virus is a large, enveloped, double stranded deoxyribonucleic acid (DNA) virus belonging to the Orthopox viridae genus of the Poxviridae family. Though, Mpox, have earlier been endemic to only African countries, the 2022 outbreak has shown its rapid spread throughout the world. The May 2022 outbreak have shown primarily human to human transmission in contrast to animal to human transmission that had been seen previously. Recent data also suggest a possibility of a pre symptomatic spread. After an incubation period of 9 days, patients with Mpox can present with a prodrome of symptoms followed by a rash. If untreated, severe complications develop in the high-risk groups especially children and pregnant woman. Such groups of people will benefit from antiviral treatments. The current approach to prevent against it is pre-exposure and post exposure prophylaxis with vaccines. The vaccines that have been approved by Food and Drug Administration to date is ACAM2000 and JYNNEOS. Several diagnostic methods exist, among which polymerase chain reaction has proven to be the most specific and sensitive. In this review, we will discuss its epidemiology, the clinical manifestations, diagnostic modalities, complications, treatment approaches and preventive measures.

Abstract
This study examined the growth characteristics, nucleotide sequence variations, and economic evaluation of two duck breeds. For this investigation, 150 each of 300 male Muscovy and Pekin ducklings aged one week were used. Body weight gain (BWG) as well as the initial and final live body weights were noted. Feed conversion ratios (FCR) and average feed intake (AFI) were also calculated. The percentages of the giblets and eviscerated carcass to live body weight were recorded after the giblets and carcass were weighed. For the purpose of extracting DNA, blood samples from ducks of each breed were taken and placed in tubes with disodium EDTA as an anticoagulant. For real-time analysis, RNA was taken from the liver and breast muscle of each breed. In terms of economic criteria, each breed's total variable costs (TVC), total costs (TC), total return (TR), net return (NR), values for the difference in net profit, and economic efficiency percent were assessed. In comparison to Pekin breed, the Muscovy breed exhibited higher ultimate BW, BWG, dressing percentages, and liver percentages. However, the Muscovy breed experienced a considerable fall in AFI and FCR. PCR-DNA sequencing of IGFBP3, FGF5, MSTN, PGAM2, ApoVLDL-II, ACACA, SCD, FASN and LPL genes revealed nucleotide sequence variations in the form of single nucleotide polymorphisms (SNPs) between Muscovy and Pekin breeds. Muscovy had a much higher gene expression profile for growth markers than Pekin breed. Muscovy breed displayed greater TR, NR, net profit difference%, and economic efficiency% compared to Pekin ducks. According to this study, Muscovy ducks showed greater growth features than Pekin ducks. Identified SNPs and the gene expression profile of growth promoters, together with economic factors, may serve as proxy indicators for selection the best breed of ducks.

Abstract
Bacterial secondary metabolites exhibit diverse remarkable bioactivities and are thus the subject of study for different applications. Recently, the individual effectiveness of tripyrrolic prodiginines and rhamnolipids against the plant-parasitic nematode Heterodera schachtii, which causes tremendous losses in crop plants, was described. Notably, rhamnolipid production in engineered Pseudomonas putida strains has already reached industrial implementation. However, the non-natural hydroxyl-decorated prodiginines, which are of particular interest in this study due to a previously described particularly good plant compatibility and low toxicity, are not as readily accessible. In the present study, a new effective hybrid synthetic route was established. This included the engineering of a novel P. putida strain to provide enhanced levels of a bipyrrole precursor and an optimization of mutasynthesis, i.e., the conversion of chemically synthesized and supplemented monopyrroles to tripyrrolic compounds. Subsequent semisynthesis provided the hydroxylated prodiginine. The prodiginines caused reduced infectiousness of H. schachtii for Arabidopsis thaliana plants resulting from impaired motility and stylet thrusting, providing the first insights on the mode of action in this context. Furthermore, the combined application with rhamnolipids was assessed for the first time and found to be more effective against nematode parasitism than the individual compounds. To obtain, for instance, 50% nematode control, it was sufficient to apply 7.8 μM hydroxylated prodiginine together with 0.7 μg/ml (~ 1.1 μM) di-rhamnolipids, which corresponded to ca. ¼ of the individual EC50 values. In summary, a hybrid synthetic route toward a hydroxylated prodiginine was established and its effects and combinatorial activity with rhamnolipids on plant-parasitic nematode H. schachtii are presented, demonstrating potential application as antinematodal agents.

Abstract
Abstract
Introduction/Objective
Myeloid/lymphoid neoplasms with rearrangement of FGFR1 are uncommon and heterogeneous group of hematological malignancies that may present as myeloproliferative neoplasm, acute myeloid leukemia, T or B lymphoblastic lymphoma/leukemia, or mixed phenotypic acute leukemia. Patients can present with lymphadenopathy, mediastinal mass, or systemic symptoms. Eosinophilia is common in peripheral blood or bone marrow. Several chromosomal rearrangements and fusion genes have been described with FGFR1 rearrangement and all of them encode an aberrant tyrosine kinase. Tyrosine kinase inhibitors may offer a prospective therapeutic approach although specific targeted therapies have yet to be established.
Methods/Case Report
We present a case of a 14-year-old male who presented with rapid neck pain and swelling. Imaging revealed a 15 x 8 x 6 cm neck mass extending into the anterior mediastinum. Laboratory evaluation revealed anemia, thrombocytopenia, and leukocytosis (41.7 K/mm3), with absolute eosinophilia and blasts of 50%. Flow cytometry of peripheral blood demonstrated a population of T-lymphoblasts comprising about 60% of the cellularity with dim CD45, cytoplasmic CD3, CD7, TdT, CD38, CD4, CD5, CD10, and CD15, supporting T-lymphoblastic leukemia/lymphoma. The patient received induction chemotherapy, and subsequent bone marrow biopsy showed morphologic remission. Six weeks from diagnosis, the patient developed a gluteal mass with an atypical T-cell infiltrate that was negative for TdT; and at 15 weeks from diagnosis, developed an enlarging abdominal mass, also with an atypical T-cell infiltrate also negative for TdT and CD1a. At that time molecular diagnostic studies of the abdominal wall mass discovered a previously unpublished ATG16L1-FGFR1 fusion, supporting myeloid/lymphoid neoplasm with FGFR1 rearrangement, T-lymphoblastic leukemia/lymphoma.
Results (if a Case Study enter NA)
NA.
Conclusion
Although a variety of translocations have been identified with FGFR1 rearrangement, the novel fusion partner ATG16L1 has not been previously reported. The case also illustrates an unusual extramedullary recurrence of the T-cell lymphoblastic leukemia/lymphoma with significant antigenic shift including loss of TdT and CD1a.

Abstract
PURPOSE Reduction of chemotherapy start times (CST) and length of stay (LOS) for elective chemotherapy admissions is a priority. The aim of this project was to improve efficiency of patient care while simultaneously increasing revenue by reducing LOS and transitioning high-cost chemotherapy to the outpatient setting. METHODS A multidisciplinary quality improvement team proposed building a new outpatient infusion suite in close proximity to the inpatient unit. This suite was then integrated into the flow of elective inpatient chemotherapy admissions and discharges for etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (EPOCH-R). Quality measures such as CST, LOS, and revenue were used to evaluate the new infusion suite. RESULTS In the pilot phase of the study, the average CST improved by approximately 1 hour 45 minutes (P = .0218). The mean LOS was reduced from 4.3 to 4.1 midnights (P = .0214). In terms of hours, LOS was reduced from 105.8 to 95.5 hours (P < .0001). A mean quarterly revenue of $309,410 US dollars was noted during the pilot that had not been previously billed. These improvements were sustained throughout the control phase. CONCLUSION Delays in CST and prolonged LOS lead to patient dissatisfaction and increased cost to the health care system. Focus groups and patient feedback are important when designing and implementing new workflows. The creation of an outpatient integrated infusion suite allows medical centers to meet patients' expectations of reducing number of visits while also reducing LOS and capturing new revenue. Adherence to scheduling guidelines further reduces the CST for elective chemotherapy administration.

Abstract
BACKGROUND The severe, acute respiratory syndrome COVID-19 that was first reported in China in December 2019 quickly became a global pandemic that has resulted in over 100 million infections and more than 2 million deaths. STUDY DESIGN This study aimed to assess the awareness level of university students regarding the possibility of becoming infected with COVID-19. In order to achieve this objective, we assessed the students' knowledge, attitudes, and behaviors using an online survey questionnaire offered to a total of 300 students. RESULTS A positive response regarding awareness of COVID-19 symptoms was registered by more than 70% of the students, whereas 62% felt that wearing a mask did not give full protection against infection, approximately 30% agreed that antibiotics and antivirals did not treat COVID-19, and 62% agreed that vitamin C was helpful in treating common symptoms of COVID-19. Moreover, around 31% of the students believed that COVID-19 is a man-made virus. Students who had gotten infected with SARS-CoV-2 believed that wearing a mask gives full protection (p=0.018). In response to survey questions related to attitude, 80% of students cancelled and postponed meetings with friends, and 90% agreed that mask-wearing is the most precautionary measure used to prevent the infection. In addition, 82% avoided coughing in public, 82% avoided contact if they felt flu-like symptoms and 80% washed their hands far more often due to the pandemic. Interestingly, 76% carried hand sanitizer, 66.5% avoided shaking hands, and 42.7% were taking vitamin C supplements. CONCLUSIONS This study showed that the participants had a positive awareness of COVID-19 transmission, symptoms, and treatments misconceptions and mistaken beliefs related to treatments and the origin of the virus were also common and should be addressed. This study thus provides a baseline for a population-based surveillance program that could help local authorities to improve pandemic preparation plans, particularly with regard to governmental education and media campaigns.

Background
Accurately determining atrial arrhythmia mechanisms from a 12-lead ECG can be challenging. Given the high success rate of cavotricuspid isthmus (CTI) ablation, accurate identification of CTI-dependent typical atrial flutter (AFL) is important for treatment decisions and procedure planning. Machine learning, with convolutional neural networks (CNNs) in particular, has been used to classify arrhythmias using the 12-lead ECG with great accuracy. However, most studies use human interpretation of the ECG as the ground truth to label the arrhythmia ECGs. Therefore, these neural networks can only ever be as good as expert human interpretation. We hypothesised a convolutional neural network could be trained to match or even exceed expert human performance in classifying CTI-dependent AFL vs. non-CTI dependent atrial tachycardia (AT), when using findings from the invasive electrophysiology (EP) study as the gold standard.
Methods
Figure 1 summarises the study methodology. We trained a CNN on data from 231 patients undergoing EP studies for atrial tachyarrhythmia. A total of 13500 5-second 12-lead ECG segments were used for training. Each case was labelled CTI-dependent AFL or non-CTI dependent AT based on the findings of the EP study. The model performance was evaluated against a test set of 57 patients. A survey of electrophysiologists and cardiologists in Europe was undertaken on the same 57 ECGs.
Results
The model had an accuracy of 86% (95% CI 0.77-0.95). The F1 score was 0.87.The AT/AFL network correctly identified AT 82% and AFL 90% of the time.
A saliency map can be used to help understand why a CNN predicted a particular outcome. This is achieved by mapping the outcome back to key areas of the input that most influenced the network in producing the classification result. Figure 2 presents the saliency mappings of an example 12-lead ECG for each class of AFL and AT. The network used the expected sections of the ECGs for diagnoses; these were the P-wave segments and not the QRS or other unexpected segments.
There were twelve respondents in the clinician survey. These respondents included nine electrophysiologists. The median accuracy was 78% (range 70-86%). The electrophysiologists had a median accuracy of 79%, (range 70-84%). Humans were more likely to incorrectly diagnose AFL as AT (on average incorrect diagnoses: 9 AFL, 1 AT). In comparison, the neural network most often incorrectly diagnosed AT as AFL (incorrect diagnoses: 5 AT, 3 AFL).
Conclusion
We describe the first neural network trained to differentiate CTI-dependent AFL from other atrial tachycardias. We found that our model surpassed expert human performance. Automated artificial intelligence enhanced ECG analysis could help guide treatment decisions and plan ablation procedures for patients with organised atrial arrhythmias.

Abstract
Increased anxiety and depressive symptoms have reported to be its association with long term illness. Because of having unwanted effects of newly available drugs, patients administering anxiolytic drugs usually discontinue the treatment before they are completely recovered. Therefore, there is a serious need to develop new anxiolytic drugs. The anxiolytic effect of hydro-alcoholic extract of Agaricus blazei in animal models was assessed. 24 male mice (Mus musculus genus) were included in the study. Four groups were prepared and each group contained six animals. The groups were vehicle control, positive control (diazepam 1.0 mg/kg, i.p.) as well as two treatment groups receiving Agaricus blazei hydro-alcoholic extract at a dose of 136.50 mg/kg and 273.0 mg/kg orally. The Marble burying test, Nestlet shredding test and Light and Dark box test used to assess anxiolytic activity. Mice administered with diazepam 1.0 mg/kg, i.p. while hydro-alcoholic extract of AbM (136.50 and 273.0 mg/kg, respectively) was administered via oral route which exhibited marked reduction in number of marbles-burying as compared to vehicle control group. Mice administered with diazepam 1.0 mg/kg, i.p. and Oral administration of hydro-alcoholic extract of AbM (136.50 and 273.0 mg/kg, respectively) exhibited significant decrease in nestlet shredding in comparison to vehicle control group. The oral administration of hydro-alcoholic extract at a dose of 136.5mg/kg and 273mg/kg showed elevation in time spent in light box and was comparable to standard treated group while time spent by mice following oral administration of hydro-alcoholic extract of Agaricus blazei at a dose of 273.0 mg/kg also showed elevation and was found to be more near to standard treated group (diazepam 1 mg/kg, i.p.).

Abstract
OBJECTIVES The role of overcrowded and multigenerational households as a risk factor for COVID-19 remains unmeasured. The objective of this study is to examine and quantify the association between overcrowded and multigenerational households and COVID-19 in New York City (NYC). STUDY DESIGN Cohort study. METHODS We conducted a Bayesian ecological time series analysis at the ZIP Code Tabulation Area (ZCTA) level in NYC to assess whether ZCTAs with higher proportions of overcrowded (defined as the proportion of the estimated number of housing units with more than one occupant per room) and multigenerational households (defined as the estimated percentage of residences occupied by a grandparent and a grandchild less than 18 years of age) were independently associated with higher suspected COVID-19 case rates (from NYC Department of Health Syndromic Surveillance data for March 1 to 30, 2020). Our main measure was an adjusted incidence rate ratio (IRR) of suspected COVID-19 cases per 10,000 population. Our final model controlled for ZCTA-level sociodemographic factors (median income, poverty status, White race, essential workers), the prevalence of clinical conditions related to COVID-19 severity (obesity, hypertension, coronary heart disease, diabetes, asthma, smoking status, and chronic obstructive pulmonary disease), and spatial clustering. RESULTS 39,923 suspected COVID-19 cases were presented to emergency departments across 173 ZCTAs in NYC. Adjusted COVID-19 case rates increased by 67% (IRR 1.67, 95% CI = 1.12, 2.52) in ZCTAs in quartile four (versus one) for percent overcrowdedness and increased by 77% (IRR 1.77, 95% CI = 1.11, 2.79) in quartile four (versus one) for percent living in multigenerational housing. Interaction between both exposures was not significant (βinteraction = 0.99, 95% CI: 0.99-1.00). CONCLUSIONS Overcrowdedness and multigenerational housing are independent risk factors for suspected COVID-19. In the early phase of the surge in COVID cases, social distancing measures that increase house-bound populations may inadvertently but temporarily increase SARS-CoV-2 transmission risk and COVID-19 disease in these populations.

Abstract
Introduction: To compare the anxiety levels demonstrated by children during cast removal procedure between oscillating saw vs cast shear methods. Material and methods: A randomised prospective study of 102 children (mean age 8.3 ± 3.5 years) with fractures involving upper or lower limbs. Children undergoing removal of cast were divided into 2 groups; either by an oscillating saw or a cast cutting shear. The level of anxiety was assessed by recording the heart rate with a portable fingertip pulse oximeter before, during and after removal of the cast. Objective assessment was performed by documenting the fear level on Children’s Fear Scale (CFS). Results: There was a significant increase in the heart rate of children during cast removal while using the oscillating saw compared to cast shear (p<0.05). The noise level produced by the saw exceeded 80 dB (mean 103.3 dB). The fear level was significantly lower in the cast shear group (p<0.05). Conclusion: The noise produced by the oscillating saw was associated with an increased anxiety level in children undergoing cast removal. Cast shear is a simple and inexpensive instrument that can be used for cast removal in overly anxious children.

Abstract
Introduction: The guided growth technique is an alternative to corrective osteotomy for treating angular deformities of the extremities. It has the advantage of being minimally invasive and is effective in a growing child. This study reports on the outcome of guided growth technique using a plate in correcting knee angular deformities. Material and Methods: We conducted a retrospective study of children with angular deformity of the knee treated by the guided growth technique from January 2010 to December 2015 in a tertiary centre. The guided growth technique was done using either the flexible titanium plate (8-plate) or the 2-hole reconstruction plate. Correction of deformity was assessed on radiographs by evaluating the mechanical axis deviation and tibiofemoral angle. The implants were removed once deformity correction was achieved. Results: A total of 17 patients (27 knees) were evaluated. Twenty-two knees (81.5%) achieved complete correction of the deformity. The median age was 4.0 (interquartile range 3.0-6.0) years and the median Body Mass Index (BMI) was 26.0 (25.0-28.0). There were 7 unilateral and 10 bilateral deformities with different pathologies (14 tibia vara, 3 genu valgus). The median rate of correction was 0.71° per month. One patient (1 knee) had screw pull-out and two patients (4 knees) had broken screws in the proximal tibia. Three patients (5 knees) failed to achieve complete correction and were subsequently treated with corrective osteotomies. Out of five patients (8 knees) who were followed-up for at least 12 months after removal of hardware, two had rebound deformities. No permanent growth retardation occurred in our patients. Conclusion: Our outcome for guided growth to correct knee angular deformity was similar to other studies. Guided growth is safe to perform in children below 12 years old and has good outcome in idiopathic genu valgus and Langeskiold II for tibia vara. Patients should be observed for recurrence until skeletal maturity following implant removal.

Abstract
e21202 Background: Increased systemic inflammatory state and increased inflammation within tumor micro-environment (TME) have been associated with a worse prognosis and lower responsiveness to immune checkpoint inhibitors (ICI). Systemic inflammatory immune index (SII) reflects the changes in the systemic inflammatory matrix. Studies have shown the association of SII with cancer survival and treatment outcomes. We aim to study the effect of SII on treatment outcomes in non-small cell lung cancer (NSCLC) patients being treated with ICI. Methods: We conducted a retrospective analysis on 178 NSCLC patients treated with ICIs (pembrolizumab, nivolumab, ipilimumab/nivolumab or atezolizumab) alone or in combination with chemotherapy. SII is the product of platelets multiplied by neutrophils divided by lymphocytes. Baseline and 8-week SIIs were obtained. Radiographic response, duration of radiographic response (date of best response to radiographic progression), overall survival (OS), and progression-free survival (PFS) were evaluated. A high SII was defined as a value greater than the median SII. Cox regression univariate and multivariate analyses were performed. Logistic regression, t-test, and Chi-square tests were applied. Results: Overall, 81% patients had adenocarcinoma and 19% patients had squamous, adenosquamous or large cell carcinoma. The majority of the patients were female (56.2% vs. 43.8%). Median SII at baseline was 1335. The objective response rate (ORR) was 45.1%. The disease control rate was 75.8%. The ORR was 51% in patients receiving ICI first-line compared to 35% in those who received ICI as a second-line therapy. At baseline, there was no difference in the mean SII between responders and non-responders (2146.2 vs. 1917.5, P = 0.5); however at 8 weeks, the mean SII was significantly lower in responders compared to non-responders (1198.8 vs. 2880.2, P = 0.02). A total of 15 (10.9%) patients were found to have pseudoprogression or mixed response on follow-up imaging. Among these, 11(73.3%) patients had low SII at 8 weeks (P = 0.04). The median OS was significantly higher in patients with low SII at baseline (29.6 months vs. 10.1 months, P = 0.001 95% CI 10.6 – 22.1). Similarly, there was a significant difference in median PFS in patients with low SII (14.6 months vs. 6.7 months, P = 0.002, 95% CI 5.6 – 11.6). There was no correlation between high or low SII on the incidence of immune-related adverse events. Conclusions: SII may have significant impact on OS and PFS and could be serially monitored to assess the response to ICI. A low SII may help to differentiate pseudoprogression vs. true progression. Prospective studies are needed to validate these findings. Further, it will be interesting to see if SII could be incorporated into predictive models to determine the duration of cytotoxic therapy in selected patients.

Abstract
e21209 Background: Immune checkpoint inhibitors (ICI) are now the standard of care in the treatment of non-small cell lung cancer (NSCLC). ICIs may be used as monotherapy or in combination with chemotherapy. Increased recruitment of inflammatory cells in the tumor micro-environment is associated with a poor response to ICIs. Although obesity is a risk factor for many types of cancers, including lung cancer, it is associated with a low systemic inflammation state. This creates an effect known as the “obesity paradox,” resulting in better treatment-related outcomes in overweight and obese patients receiving ICIs. However, in obese patients, the neutralizing interleukin (IL) - 1β level is high, which can decrease the responsiveness to ICI. We aim to study the effect of increased weight on treatment-related outcomes in NSCLC patients receiving ICI. Methods: We conducted a retrospective analysis on 178 NSCLC patients treated with ICIs, such as pembrolizumab, nivolumab, ipilimumab/nivolumab or atezolizumab, alone or in combination with chemotherapy. Overweight was defined as having a BMI of 25 – 29.9 while obesity was defined as having a BMI of ≥ 30. Overall survival (OS), progression free survival (PFS), best radiographic response, and the time to achieve radiographic response were evaluated. Cox regression univariate and multivariate analyses were performed. Logistic regression and Chi-square tests were applied. Results: Of the 178 patients with NSCLC, 81% had adenocarcinoma, and 19% had squamous, adenosquamous, or large cell carcinoma. The majority of patients were female (56.2% vs. 43.8%). Overall, 48.6% patients were overweight or obese. The objective response rate (ORR) was 45.1% and the disease control rate (DCR) was 75.8%. The ORR was 37% in overweight/obese patients compared to 52% in patients with a normal weight (p = 0.06). The DCR was 76% vs. 73.9%, (p = 0.7). The median time to achieve the best radiographic response was 3.7 months in overweight/obese patients compared to 2.5 months in those of normal weight (p = 0.2). A considerably higher proportion of the patients progressed in overweight/obese category (80.7% vs. 69.3%, P = 0.08). However, there was no significant difference in median PFS between the two categories (7.4 vs. 8.1 months, P = 0.2). The overall survival was not significant different between both categories (15.9 vs. 16.8 months, P = 0.5). Conclusions: Our study suggests that obesity and overweight status can result in a low response rate to ICIs in NSCLC patients and can delay the time to achieve the best radiographic response per RECIST criteria. However, we did not observe any significant impact on the overall or progression-free survival. A large, population-based study will help to elucidate the impact of weight on the responsiveness to ICI.

Abstract
e21137 Background: Immune checkpoint inhibitors (ICI) are the standard of care in the treatment of non-small cell lung cancer (NSCLC). ICIs are commonly used in combination with chemotherapy but may be used as monotherapy in selected cases. Registration trials have shown a response rate of 40–50% in such patients and a durable response in some patients. However, there are no reliable predictive markers that determines the response and its durability. Recruitment of the inflammatory cells in the tumor microenvironment (TME) can determine the response to ICIs and an increased inflammatory state can be a poor prognostic factor. Peripheral inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) can reflect the inflammatory changes within the TME. We aim to study the effect of high NLR and PLR on the radiographic response and its durability in NSCLC patients treated with ICIs. Methods: We conducted a retrospective analysis on 178 NSCLC patients treated with ICIs such as pembrolizumab, nivolumab, ipilimumab/nivolumab or atezolizumab either alone or in combination with chemotherapy. Radiographic response, and the duration of radiographic response (date of best response to radiographic progression), NLR, and PLR were calculated at baseline and 8 weeks since the start of ICI. High NLR and PLR was defined as greater than the median NLR and PLR values. Cox regression univariate and multivariate analyses were performed. Logistic regression and Chi-square tests were applied. Results: Overall 81% patients had adenocarcinoma and 19% patients had squamous, adenosquamous or large cell carcinoma. Majority of the patients were female (56.2% vs. 43.8%). The objective response rate (ORR) was 45.1% and the disease control rate (DCR) was 75.8%. The ORR was 51% in patients receiving ICI as first line therapy compared to 35% in patients who received ICI as a second line therapy. There was statistically significant difference in median duration of response in patients with high vs. low NLR (9.8 months vs. 18 months, P = 0.01, 95% CI 10.9– 26.2) and high vs. low PLR (9.0 months vs. 17 months, P = 0.03 95% CI 10.9–24.33) at baseline. The baseline odds ratio (OR) of response in the high NLR and high PLR group was 0.73 (P = 0.5, 95% CI 0.36–1.64) and 0.63 (P = 0.2, 95% CI 0.32–1.23), respectively. However, the odds to respond to ICI decreased significantly in patients with high NLR and PLR at 8 weeks [NLR (OR = 0.16, P = 0.0001, 95% CI 0.06–0.43)] and [PLR (OR = 0.27, P = 0.005, 95% CI 0.1–0.6). Conclusions: NLR and PLR may be reliable surrogate markers determining the durability of response to ICI in NSCLC patients. Standard imaging studies and serial monitoring may be beneficial to monitor the response to ICIs. However, prospective studies are needed to develop predictive and prognostic models utilizing these indices.

Abstract
Femoral neck stress fractures are rare in children. To the best of our knowledge, the tension type stress fracture has been reported only twice in the English language literature. We report on a five years follow-up of a 10-year-old boy with this injury which was initially missed. The fracture healed after screw fixation. We highlight the importance of considering stress fracture as a differential diagnosis in a child with chronic hip pain. A careful physical examination and the appropriate imaging will avoid missing the diagnosis.

Abstract
Welding fumes has been known to cause release of reactive oxygen species which stands to be cytotoxic. The study aims to assess the histopathological changes of some organs associated with exposure to welding fumes in experimental animals. The metal fumes were obtained from sites of welding. A total of 130 male albino rats were engaged and divided into a 13 groups. Out of which 12 were given respective doses calculated to be equivalent to worker's real life exposure times and 1 as control. The doses were intratracheally administered weekly following anesthetization for a period of 12 weeks. The laboratory rats were then sacrificed and target organs were examined. Histopathological examination reveals normal feature for brain tissues in all treated animals. However, there was lymphocyte hyperplasia and necrosis in heart, kidney, liver and lungs tissues which at lower doses were slight and became moderate at higher doses. In addition, there were'nt pathological changes in tissues of the control animals. Thus, exposure to metal welding fumes has caused damages that have translated into lesions and several pathologies in kidney, lungs, liver and heart tissues of the test animals. Regulation and control should be imposed on exposure to welding fumes by metal workers.

Mitral (M), aortic (A), tricuspid (T) valves (V) E features (thickness, mobility, calcification, and function), their evolution over the time and the behaviour with Enzyme replacement therapy (ERT) or bone marrow transplant (BMT) were assessed.
Result
52% male, mean age 21 yrs ranges 16 to 48 yrs. 5% of the patient had MPS type I, 11% MPS type II, 29% MPS type IV, and 52% MPS type VI. 70% received ERT and 11% BMT.
In the severe case all the valves were involved (panel A, B, C; white arrows point to valve leaflets; yellow arrows MV apparatus) the whole MV apparatus was involved since the earlier stage and in the latest stage the calcification was massive (panel C). The predominant valvular dysfunction was the regurgitation followed by mixed disorder while the most frequent severe lesion was the stenosis; the echocardiographic pattern differs from the classical hockey stick appearance of the early phase of rheumatic MV and the thickening is different from the myxomatous MV for the reduced mobility and the presence of calcification. The reduced mobility of the TV (panel C) also differs from the Loeffler syndrome because of the restriction of the leaflets and the association with thickening and calcification. Under treatment, the MV thickening was found to have a slow progression of less than 1 mm yearly in 61% cases.
Conclusion
Our results showed that all the valves are affected mainly the MV; the echocardiographic pattern of MPS, different from other valvular diseases of adolescent and adult age, can help in avoiding misdiagnose. Our observations also suggest that the cardiac involvement show slow rate of progression after the initiation of the therapy. Further studies are required to confirm our results.

Abstract
The test and slaughter policy of the federal government of Nigeria on contagious bovine pleuropneumonia (CBPP) in cattle is no longer feasible because it lacked the political will as a result, farmers tend to treat their cattle of the disease most which has been ineffective. herefore, the quest for a supportive clinical management protocol for CBPP in cattle aimed at enabling the cow regain its body condition in order to allow the farmer sell the cow for slaughter at a profit was the aim of this case report. A 6-year-old Bunaji cow weighing 350kg with history of not feeding well, lagging behind during grazing, difficulty in breathing, intermittent cough and bloat was presented. Physical examination was carried out and differential diagnoses which included contagious bovine pleuropneumonia, mango choke, Pasteurellosis and tuberculosis were considered. After a careful scrutiny of the differentials, a tentative diagnosis of contagious bovine pleuropneumonia which was confirmed by the Latex agglutination test (LAT) was arrived at. A supportive clinical management protocol was instituted with the sole aim of enabling the cow regain its body condition in order to allow the farmer sell the cow for slaughter at a profit. The protocol involved isolation of the cow and administration of 20% tetracycline long acting through a combination of conventional (intra-muscular) and non-conventional (intra-venous) routes of administration along with an anti-inflammatory agent and an appetite stimulant. Six days after the commencement of therapy, the observed clinical signs subsided greatly and the cow became apparently healthy. The study showed that, the protocol of administering 20%tetracycline long acting through a combination of conventional (intra-muscular) and nonconventional (intra-venous) routes along with an anti-inflammatory agent (dexamethasone) and an appetite stimulant (vit. B. complex) was effective and profitable to the farmer. The client was advised to sell the cow for slaughter after observing the 21- day withdrawal period of the drugs.

Abstract
Predatory journals and conferences have little or no peer review. Their raison d'être is for making money through the article processing charges and the conference registration fees. Without a critical evaluation, predatory journals publishing flawed results and conclusions would cloud the existing scientific literature. Predatory conferences are the offshoots of predatory publishing. The conferences are not organised by learned societies, but by profit-making event organisers. There is a need for awareness among researchers and clinicians regarding predatory publishing. The scourge of predatory publishing and conferencing should be more often highlighted during scientific meetings and publication courses.

Abstract
Background:A third of knee osteoarthritis presents with bilateral symptomatic arthritis. In these patients, treatment options include either a staged Unilateral Total knee arthroplasty (UTKA) procedure, or a simultaneous Bilateral TKA (BTKA) procedure. Even though literature regarding outcomes in BTKA procedure has not consistently been favorable, it remains popular in select patients due to use of a single anesthetic, shorter overall surgical time, lower cost and lower overall use of narcotics. African Americans (AAs) have lower utilization and worse outcomes in UTKA literature. It is unclear whether these racial variations extend to BTKA.Objectives:We sought to examine BTKA vs UTKA utilization rates and outcomes comparing AA and White patients.Methods:National Inpatient Sample (NIS) - Healthcare Cost and Utilization Project (HCUP) database (2007-2016) was used. We identified all patients ≥ 50 years who underwent elective primary TKA using ICD-9-CM code 81.54 for UTKA and BTKA from January 1, 2012 to September 30, 2015, and ICD-10-CM codes 0SRC0x and 0SRD0x thereafter. Patients with inflammatory arthritis, pathologic fractures, metastatic disease and avascular necrosis were excluded. Major in-hospital complications included post-operative myocardial infarction, prosthetic device complication, surgical wound infection, and venous thromboembolism. Differences in temporal trends in utilization and major in-hospital complications of BTKA vs UTKA were compared between AAs and Whites. Multivariable logistic regression models were used to assess differences in both these trends between AAs and Whites after adjusting for individual (age, sex, Elixhauser comorbidity index, and morbid obesity), hospital level (hospital volume, bed size, region and teaching status) and community level (median household income) variables. Discharge weights were used to enable nationwide estimates. Multiple imputation was performed for missing race variable (11.9%).Results:From 2007 to 2016, an estimated 276,194 BTKA (unweighted observations 56,675) and 5,528,429 UTKA (unweighted observations 1,131,329) were identified (Table 1). Females had a higher proportion of TKAs performed (62.1% UTKA vs 55.9% BTKA). Patients had fewer comorbidities (measured by the Elixhauser Index) when undergoing BTKA compared to UTKA. The proportion of BTKA amongst all TKAs declined from 5.53% in 2007-08 to 4.03% in 2015-16. AAs continued to have significantly lower proportion of BTKA utilization compared to Whites (4.68% in AAs vs 6.08% in Whites in 2007-08, whereas 3.28% in AAs vs 4.19% in Whites in 2015-16, adjusted p < 0.001) (Figure 1a). In-hospital complication rates for UTKA and BTKA were significantly higher in Whites compared to AAs throughout the study period (0.77% in AAs vs 0.9% in Whites in 2007-08, whereas 0.69% in AAs vs 0.83% in Whites in 2015-16, adjusted p < 0.001) (Figure 1b). The results were similar after imputation of missing race values.Conclusion:In this nationwide sample of patients from 2007 to 2016, we found that AAs have lower utilization rate of BKTA compared to Whites, however the in-hospital complication rates were significantly higher in Whites.References:N/ATable 1.Weighted frequencies and percentages of demographic characteristics among unilateral TKA vs. bilateral TKA (N = 6, 236, 426).VariableUnilateral TKABilateral TKAPaN = 5,528,429(Unweighted N = 1,131,329)N = 276,194(Unweighted N = 56,675)Patient CharacteristicsAge, mean (SD)67.4 (0.02)65.0 (0.06)<.0001Sex: Female, n(%)3,429,484 (62.1)154,442 (55.9)<.0001Race, n(%): White4,051,648 (50.9)212,468 (76.9)<.0001 African American352,933 (6.4)14,441 (5.2) Other464,407 (8.4)16,443 (6.0) Missing659,439 (11.9)32,842 (11.9)Morbid Obesity, n(%)401,892 (7.3)20,411 (7.4)0.47Elixhauser Indexd, n(%):<.0001 0716,559 (13.0)41,550 (15.0) 1-44,484,941 (81.1)220,638 (80.0) ≥ 5326,928 (5.9)14,007 (5.1)Disclosure of Interests:Bella Mehta: None declared, Kaylee Ho: None declared, Jennifer Bido: None declared, Michael Parks Consultant of: Zimmer Biomet, Linda Russell: None declared, Susan Goodman Shareholder of: Reginosine- Investment, Grant/research support from: Novartis, Horizon, Consultant of: Novartis, Celgene, UCB, Said Ibrahim: None declared

Abstract
Abstract
Introduction
Central sleep apnea (CSA) is unique sleep breathing phenotype in patients with advanced chronic heart failure (HF) and portend poor prognosis. The prevalence of CSA in HF patients under contemporary therapy is uncertain.
Methods
We reviewed consecutive HF patients on optimal medical therapy who underwent clinically indicated diagnostic in-lab polysomnography at a single academic center. Age, sex and BMI matched patients without HF were selected from sleep clinic as a control. Patients with atrial fibrillation were excluded from this study. Apnea subtypes were determined after careful scoring and confirmation by sleep physicians. ‘Any CSA’ was defined by central apnea index (CAI) >5 and >1/hr. ‘True CSA’ was defined if met both CAI≥5/hr and > obstructive apnea index (OAI). Obstructive sleep apnea (OSA) was defined if apnea hypopnea index >15 and OAI>CAI. Multivariate analysis was performed using logistic regression adjusting for age, sex, HF and systolic dysfunction as appropriate.
Results
In patients with HF (N=95, mean age 59, female: 50%), CSA was low and was comparable to control group (N=94) (HF vs. Non-HF; CSA: 5.3 vs. 4.3%, P=NS; Any CSA 14.7 vs. 17%, P=NS). Only 3 patients with HF had true CSA. In contrast, OSA was common in both groups regardless of obesity status (52.3 vs. 55.3%). In patients with HF, Cheyne Stokes respiration was more frequent in patients with Any CSA vs. without Any CSA (13.3 vs. 3.8%, p=0.04). In multivariate analysis, presence of OSA, but not HF, was associated with Any CSA in entire cohort (Any CSA OR: 3.1 [1.3, 8.1], p=0.02). In patients with HF, male sex was associated with Any CSA (OR: 5.3 [1.1, 40.8], p=0.05). Exclusion of patients with high BMI did not change the results.
Conclusion
CSA was rare in patients with stable HF on contemporary optimal medical therapy.

Abstract
In this research work, nanowires were grown on brass (Cu - 37.2 wt% Zn) substrate by thermal oxidation. The substrate was oxidized at temperatures ranging from 350 °C to 600 °C in the presence of varying concentrations of O2 (1%-100%) in N2 flown at a rate of 200 sccm. The oxidized brass surface was characterized by field emission scanning electron microscope equipped with energy dispersive x-ray spectroscope and transmission electron microscope. Four different types of morphological variations such as thin, thick with branches, circular-flake and flat-cone shape nanostructures were observed during oxidation at different conditions. However, the prevalence of thin and thick morphology with branches was more prominent and found in all growth conditions. The length and diameter of the nanowires varied from 1 to 30 μm and 50 to 500 nm, respectively, whereas the length of the branches varied from 1 to 3 μm. The composition of the nanowires was ZnO possessing of hexagonal wurtzite structure. The selected area diffraction confirms that the nanowires grew along 〈1 1 [Formula: see text] 0〉 directions. Based on the results, a stress induced mechanism is proposed for the growth of ZnO nanowires on Cu - 37.2 wt% Zn substrate.

Abstract
ZusammenfassungDie Ursprünge der Lübecker Universitäts-Hautklinik reichen in die 30er-Jahre des letzten Jahrhunderts zurück. Die Klinik hat in den letzten Jahrzehnten eine konsequente bauliche und inhaltliche Weiterentwicklung erfahren und verfügt heute über 85 Betten auf 2 Stationen und in einer Tagesklinik. Ein modernes Weiterbildungsprogramm, das auf einem Rotationsprinzip durch 5 verschiedene stationäre und ambulante Teams beruht, vermittelt alle wesentlichen Lerninhalte der Dermatologie. Die Erweiterung der Klinik in den letzten Jahren beruhte auf einer engen Interaktion von Grundlagenforschung und klinischer Tätigkeit, insbesondere auf dem Gebiet kutaner Autoimmunerkrankungen und entzündlicher Dermatosen. Die wissenschaftliche Entwicklung der Hautklinik profitierte seit 2007 insbesondere von der Förderung durch die Exzellenzinitiative des Bundes (Exzellenzcluster Inflammation at Interfaces). Daneben wurde durch die Deutsche Forschungsgemeinschaft (DFG) seit 2011 unter Federführung der Hautklinik ein Graduiertenkolleg Modulation of Autoimmunity gefördert, das zur Entwicklung des wissenschaftlichen Nachwuchses und zur Ausbildung zahlreicher naturwissenschaftlicher und medizinischer Doktoranden/Doktorandinnen1 beitrug. Seit 2015 besteht an der Klinik auch eine Klinische Forschungsgruppe der DFG zum Thema Pemphigoid Diseases – Molecular Pathways and their Therapeutic Potential. Im Jahr 2018 haben Mitarbeiter der Klinik wesentlich zur Einwerbung eines Clinician Scientist-Programms der DFG beigetragen, das die wissenschaftliche Ausbildung forschender Kliniker verbessern soll. In den letzten Jahren haben sich aus der Lübecker Hautklinik heraus 2 eigenständige Institute neu etabliert. Hierzu zählen das Institut für Entzündungsmedizin unter der Leitung von Prof. Diamant Thaçi, in dem klinische Studien zu entzündlichen Hauterkrankungen initiiert und koordiniert werden und die Versorgung von Patienten mit entzündlichen Dermatosen stattfindet. Daneben ist aus der Hautklinik heraus das Lübecker Institut für Experimentelle Dermatologie (LIED) entstanden, in dem derzeit 5 Professoren mit ihren jeweiligen Arbeitsgruppen zu unterschiedlichen Themen der Entzündung an der Haut forschen. Die interdisziplinären wissenschaftlichen Aktivitäten zur Entzündung an der Haut am Lübecker Campus werden seit 2015 in einem Center for Research on Inflammation of the Skin (CRIS) gebündelt. CRIS erhielt kürzlich die Zusage für ein eigenständiges Forschungsgebäude, das nach § 91 Grundgesetz durch Bund und Land finanziert wird und derzeit im Zentrum des Lübecker Campus entsteht. Der Ausbau der Forschungsstrukturen der Klinik ging mit der Einrichtung von Spezialambulanzen für verschiedene entzündliche Hauterkrankungen, aber auch für die Versorgung von Hautkrebs und chronischen Wunden einher. Die Klinik verfügt über ein zertifiziertes Hautkrebszentrum und ist Teil der Lübecker universitären Gefäß- und Krebszentren. Weitere wichtige Pfeiler der klinischen Versorgung sind zertifizierte diagnostische Einsendelabore für Dermato-Histopathologie und kutane Autoimmunerkrankungen.

Abstract
BACKGROUND SPLIT was founded in 1995 in order to collect comprehensive prospective data on pediatric liver transplantation, including waiting list data, transplant, and early and late outcomes. Since 2011, data collection of the current registry has been refined to focus on prospective data and outcomes only after transplant to serve as a foundation for the future development of targeted clinical studies. OBJECTIVE To report the outcomes of the SPLIT registry from 2011 to 2018. METHODS This is a multicenter, cross-sectional analysis characterizing patients transplanted and enrolled in the SPLIT registry between 2011 and 2018. All patients, <18 years of age, received a first liver-only, a combined liver-kidney, or a combined liver-pancreas transplant during this study period. RESULTS A total of 1911 recipients from 39 participating centers in North America were registered. Indications included biliary atresia (38.5%), metabolic disease (19.1%), tumors (11.7%), and fulminant liver failure (11.5%). Greater than 50% of recipients were transplanted as either Status 1A/1B or with a MELD/PELD exception score. Incompatible transplants were performed in 4.1%. Kaplan-Meier estimates of 1-year patient and graft survival were 97.3% and 96.6%. First 30 days of surgical complications included reoperation (31.7%), hepatic artery thrombosis (6.3%), and portal vein thrombosis (3.2%). In the first 90 days, biliary tract complications were reported in 13.6%. Acute cellular rejection during first year was 34.7%. At 1 and 2 years of follow-up, 39.2% and 50.6% had normal liver tests on monotherapy (tacrolimus or sirolimus). Further surgical, survival, allograft function, and complications are detailed.
