Methods Adults (≥18 years) undergoing elective sleeve gastrectomy or gastric bypass (laparoscopic and open) were identified in the 2016-2018 Nationwide Readmissions Database. International Classification of Diseases 10th Revision codes for deep venous thrombosis and/or pulmonary embolism were used to ascertain the presence of VTE. Multivariable linear and logistic models were developed to evaluate the independent association of VTE with outcomes of interest. Results Of an estimated 537,522 patients meeting inclusion criteria, .55% developed VTE during index hospitalization (.14%) or within 90 days of index discharge (.41%). Compared to others, VTE patients were older (51.8 vs 44.9 years, P<.001), more commonly male (20.0% vs 31.5%, P<.001), and had gastric bypass (56.3% vs 31.9%, P<...

The present work examined a nationally representative sample of all major operations to identify factors associated with RFB. Study Design The 2005-2017 National Inpatient Sample was used to identify adults undergoing cardiac, neurosurgical, orthopedic, genitourinary, gastrointestinal, vascular, and thoracic operations. International Classifications of Diseases 9th-10th Revisions diagnosis codes were used to identify instances of RFB. Results Of an estimated 71,445,042 hospitalizations, .02% had a diagnosis of RFB, with decreasing incidence from .03 to .02% over the study period (NPtrend < .001). Relative to vascular operations, gastrointestinal (adjusted odds ratio [AOR] 2.12), thoracic (AOR 1.80), and multi-cavity (AOR 2.17) were associated with greater odds of RFB. Laparoscopic approach (AOR .33) and trauma-associated admission (AOR .52, all P < .001) were associa...

Hospital variation in the development of respiratory failure after pulmonary lobectomy: A national analysis

Surgery

The present study evaluated factors associated with respiratory failure and sought to ascertain the presence of interhospital variation. METHODS The 2016-2018 Nationwide Readmissions Database was queried to identify elective adult (≥18 years) hospitalizations for pulmonary lobectomy with the diagnosis of lung cancer. Multi-level, mixed-effects models were developed to identify factors associated with respiratory failure and evaluate its associated in-hospital mortality, length of stay, and hospitalization costs. Random effects were predicted with Bayesian methodology and used to rank hospitals by increasing respiratory failure risk attributable to each institution. RESULTS Of an estimated 70,992 patients, 8.0% developed respiratory failure. Compared to those without, patients with respiratory failure were on average older and less commonly female. After multivariable adjustment, coagulopathy, pulmonary circulation disorders, and open operative approach were associated with increased odds of respiratory failure. However, relative to right upper, right middle resections were associated with a reduction in likelihood of respiratory failure. Approximately 27% of the variance in respiratory failure was attributable to the hospital-level effects, with baseline risk ranging from 0.1% to 20.7%. Notably, respiratory failure was associated with increased mortality, longer length of stay, and greater hospitalization costs. CONCLUSION The present work identified several factors associated with respiratory failure after lobectomy and found it to be associated with inferior clinical outcomes and greater resource use. We noted significant interhospital variation in the development of respiratory failure, suggesting the need for systemic quality improvement efforts.

Image fusion based enhancement in framelet domain

But some problems like blurring may degrade the quality of images. Image processing has a lot of popular techniques to improve the images. But sometimes single image is not sufficient to enhance the image, effectively. The similar images can be enhanced where some different parts are degraded due to some problems such as blurring. With this motivation, images are enhanced using fusion technique. We propose a scheme using DCT and PCA in framelet domain. For result analysis, proposed scheme is tested using mean square error (MSE) and PSNR. A comparison is also performed to examine the performance of proposed scheme. From experimental evaluation, it was observed that proposed scheme is giving better results in compare to some of recent existing schemes.

Quasi-Z-Source Inverter (QZSI) is an enhancement to Z-Source Inverter (ZSI). The QZSI inherits all the advantages of the ZSI, which can realize buck/boost, inversion and power conditioning in a single stage with improved reliability. In addition, the proposed QZSI has the unique advantages of lower component ratings and constant dc current from the source. The QZSI features a wide range of voltage gain which is suitable for applications in photovoltaic (PV) systems, due to the fact that the PV cell’s output varies widely with temperature and solar irradiation. MATLAB / SIMULINK model of both the circuit topology (QZSI and ZSI) with different loading conditions are presented. Maximum Boost control technique is employed here. Theoretical analysis of voltage boost, control methods and a system design guide for the QZSI in PV systems are investigated in this paper. A comparative analysis between...

This approach suffers both false positives (i.e. finding errors where there are not any) and false negatives (missing out on actual errors). In this paper, we present a novel system which emulates manual evaluation of programming assignments based on the structure and not the functional output of the program using structural similarity between the given program and a reference solution. We propose an evaluation rubric for scoring structural similarity with respect to a reference solution. We present an ML based approach to map the system predicted scores to the scores computed using the rubric. Empirical evaluation of the system is done on a corpus of Python programs extracted from the popular programming platform, HackerRank, in combination with programming assignments submitted by students undertaking an undergraduate Python programming course. The preliminary results have been encouraging with the errors reported being as low as 12 percent with a deviation of about 3 percent, showing that the automatically generated scores are in high correlation with the instructor assigned scores.

Outcomes and Resource Use Associated With Acute Respiratory Failure in Safety Net Hospitals Across the United States

RESEARCH QUESTION How does safety net burden impact outcomes of acute respiratory failure hospitalizations such as mortality, tracheostomy and resource utilization? STUDY DESIGN AND METHODS This was a retrospective cohort study using the National Inpatient Sample 2007-2017. All patients hospitalized with a primary diagnosis of acute respiratory failure were tabulated using the International Classification of Diseases 9thand 10thRevision codes and safety net burden was calculated using previously published methodology. High and low burden hospitals were generated from proportions of Medicaid and uninsured patients. Trends were analyzed using a non-parametric rank-based test while multivariable logistic and linear regression models were utilized to establish associations of safety net burden with key clinical outcomes. RESULTS Of an estimated 8,941,334 hospitalizations with a primary diagnosis of acute respiratory failure, 33.9% were categorized at low burden hospitals (LBH) and 31.6% at high burden hospitals (HBH). In-hospital mortality significantly decreased at HBH (22.8%-12.6%, nptrend<0.001) and LBH (22.0%-10.9%, nptrend<0.001) over the study period, as did tracheostomy placement (HBH: 5.6%-1.3%, LBH: 3.5%-0.8%, all nptrend<0.001). After adjustment for patient and hospital factors, HBH was associated with increased odds of mortality (AOR: 1.11, 95% CI: 1.10-1.12) and tracheostomy use (AOR: 1.33, 95% CI: 1.29-1.37), as well as greater hospitalization costs (β: +$1,083, 95% CI: 882-1,294) and longer lengths of stay (β: +3.3 days, 95% CI: 3.2-3.3). INTERPRETATION After accounting for differences between patient cohorts, high safety net burden was independently associated with inferior clinical outcomes and increased costs following acute respiratory failure hospitalizations. These findings emphasize the need for healthcare reform in order to ameliorate disparities within these safety net centers, which treat our most vulnerable populations.

Impact of Postoperative Infections on Readmission and Resource Use in Elective Cardiac Surgery

The present study characterized the impact of healthcare-acquired infection (HAI) on index hospitalization costs and post-discharge healthcare utilization. METHODS Adults undergoing elective coronary artery bypass grafting (CABG) and/or valve operations were identified in the 2016-2018 Nationwide Readmissions Database. Infections were categorized into bloodstream, gastrointestinal, pulmonary, surgical site, or urinary tract infections. Generalized linear or flexible hazard models were used to assess associations between infections and outcomes. Observed-to-expected (O/E) ratios were generated to examine inter-hospital variation in HAI. RESULTS Of an estimated 444,165 patients, 8.0% developed HAI. Patients with HAI were older, had a greater burden of chronic diseases, and more commonly underwent CABG/valve or multi-valve operations (all p<0.001). HAI was independently associated with mortality (odds ratio 4.02, 95% CI 3.67-4.40), non-home discharge (3.48, 95% CI 3.21-3.78), and a cost increase of $23,000 (95% CI 20,900-25,200). At 90 days, HAI was associated with greater hazard of readmission (1.29, 95% CI 1.24-1.35). Pulmonary infections had the greatest incremental impact on patient-level ($24,500, 95% CI 23,100-26,00) and annual cohort costs ($121.8 million, 95% CI 102.2-142.9 million). Significant hospital level variation in HAI was evident, with O/E ranging from 0.17 to 4.3 for cases performed in 2018. CONCLUSIONS Infections following cardiac surgery remain common and are associated with inferior outcomes and increased resource use. The presence of inter-hospital variation in this contemporary cohort emphasizes the ongoing need for systematic approaches in their prevention and management.

The Impact of Expedited Discharge on 30-Day Readmission After Lung Resection: A National Study

The present study examined the impact of expedited discharge on hospitalization costs and unplanned readmissions using a nationally-representative sample. In addition, we sought to determine inter-hospital practice variation. METHODS Adults undergoing elective lobar or sublobar resection were identified using the 2016-2018 Nationwide Readmissions Database, while those with postoperative duration of hospitalization >5 days or experienced any perioperative complication, were excluded. Patients were classified as Expedited if postoperative hospitalization was 0 or 1 day and otherwise as Routine. Inverse probability of treatment weighing was utilized to adjust for intergroup differences. Hospitals were ranked according to risk-adjusted early discharge rates. Multivariable regression models were developed to assess the association of expedited discharge on nonelective 30-day readmissions as well as associated mortality and costs. RESULTS Of an estimated 84,152 patients, 13,834 (16.4%) comprised the Expedited group. Compared to Routine, Expedited were younger, less likely to have chronic obstructive pulmonary disease and undergo open procedures. Following adjustment, early discharge was associated with lower incremental costs (β coefficient: -$3.6K, 95%CI: -4.4 - -2.8) as well as similar readmissions (odds ratio: 0.89, 95%CI: 0.70 - 1.13) and related-mortality. Nearly half (48.1%) of all hospitals performed zero early discharges. CONCLUSIONS Expedited discharge following lung resection is a feasible management strategy and is associated with decreased costs and similar readmission risk compared to the norm. Select individuals should be strongly considered for expedited discharge following lung resection.

The derivation of an International Classification of Diseases, Tenth Revision–based trauma-related mortality model using machine learning

Although easy to calculate, it requires additional administrative coding. International Classification of Diseases (ICD)–based models such as the Trauma Mortality Prediction Model (TMPM-ICD10) circumvent these limitations, but they use linear modeling, which may not adequately capture the intricate relationships of injuries on mortality. Using ICD-10 coding and machine learning (ML) algorithms, the present study used the National Trauma Data Bank to develop mortality prediction models whose performance was compared with logistic regression, ISS, and TMPM-ICD10. METHODS The 2015 to 2017 National Trauma Data Bank was used to identify adults following trauma-related admissions. Of 8,021 ICD-10 codes, injuries were categorized into 1,495 unique variables. The primary outcome was in-hospital mortality. eX...

Using qPCR and high-resolution sensor data to model a multi-species Pseudo-nitzschia (Bacillariophyceae) bloom in southeastern Australia

In the current study we characterized a bloom of species of Pseudo-nitzschia that occurred in a south-eastern Australian oyster-growing estuary in 2019. Using light microscopy, combined with molecular (ITS/5.8S and LSU D1-D3 rDNA regions) and toxicological evidence, we observed the bloom to consist of multiple species of Pseudo-nitzschia including P. cf. cuspidata, P. hasleana, P. fraudulenta and P. multiseries, with P. cf. cuspidata being the only species that produced domoic acid (3.1 pg DA per cell). As several species of Pseudo-nitzschia co-occurred, only one of which produced DA, we developed a rapid, sensitive and efficient quantitative real-time polymerase chain reaction (qPCR) assay to detect only species belonging to the P. pseudodelicatissima complex Clade I, to which P. cf. cuspidata belongs, and this indicated that P. cuspidata or closely related strains may have dominated the Pseudo-nitzschia community at this time. Finally, using high resolution water temperature and salinity sensor data, we modeled the relationship between light microscopy determined abundance of P. delicatissima group and environmental variables (temperature, salinity, rainfall) at two sites within the estuary. A total of eight General Linear Models (GLMs) explaining between 9 and 54% of the deviance suggested that the temperature (increasing) and/or salinity (decreasing) data were generally more predictive of high cell concentrations than the rainfall data at both sites, and that overall, cell concentrations were more predictive at the more oceanic site than the more upstream site, using this method. We conclude that the combination of rapid molecular methods such as qPCR and real-time sensor data modeling, can provide a more rapid and effective early warning of harmful algal blooms of species of Pseudo-nitzschia, resulting in more beneficial regulatory and management outcomes.

However, response rates are less than 50% and the basis for poor response is currently unknown. A patient's potential to respond cannot be currently determined until after multiple cycles of AZA treatment and alternative treatment options for poor responders are limited. To address these fundamental questions, we enrolled patients on a compassionate access program prior to the listing of AZA on the pharmaceuticals benefit scheme in Australia. We have collected bone marrow from 18 patients (10 MDS, 8 CMML) at seven different stages of treatment, starting from before treatment until after six cycles of AZA treatment, and isolated high-purity CD34+ HSPCs at each stage....

The purpose of this study was to assess the differences in incidence of RHF and outcomes between 2 types of continuous-flow LVADs at a single center. Methods: From January 2012 through June 2016, 184 patients were implanted with a continuous-flow LVAD (161 patients with the HeartMate II and 23 patients with the HeartWare device) either as a bridge to transplant or as destination therapy. Preoperative demographics, medical history, laboratory values, hemodynamics, and device type were analyzed to determine the variables associated with RHF and mortality. Results: Preoperative variables between the 2 groups were homogeneous. Most patients were Interagency Registry for Mechanically Assisted Circulatory Support profile 1 or 2 (92%) and New York Heart Association class IV (81%). More patients in the Heart-Mate II group had the indication of destination therapy (54% vs 30%), while more patients in the HeartWare group were implanted as bridge to transplant (70% vs 46%). RHF occurred in 57% of HeartWare patients compared to 16% of patients who received the HeartMate II (P=0.0001). After propensity score analysis, patients receiving the HeartWare device had increased odds for RHF (P=0.0013) and renal failure requiring dialysis (P=0.0135). The HeartMate II patient survival rate exceeded the HeartWare patient survival rate at 1 year (82.1% vs 67.2%) and at 2 years (74.6% vs 61.7%), but this difference did not achieve statistical significance (log-rank P=0.087). Conclusion: These results indicate that device type may affect RHF incidence and mortality. Studies at other centers are needed to replicate these findings.

In this study we explored the effects that dataset and model selection have on the phylogenetic inference of the Gonyaulacales, single celled marine algae of the phylum Dinoflagellata with genomes that show extensive paralogy. We developed a method for identifying and extracting single copy genes from RNA-seq libraries and compared phylogenies inferred from these single copy genes with those inferred from commonly used genetic markers and phylogenetic methods. Comparison of two datasets and three different phylogenetic models showed that exclusive use of ribosomal DNA sequences, maximum likelihood and gene concatenation showed very different results to that obtained with the multi-species coalescent. The multi-species coalescent has recently been recognized as being robust to the inclusion of paralogs, includin...

(2017) in Marine Pollution Bulletin, attempts to link environmental changes with harmful algal blooms (HABs) and human health impacts around the world. On several occasions, the links/claims presented by the authors appear exaggerated given the evidence, and in other cases, are factually inaccurate. Our scientific community strongly supports research that links HABs and human health. However, we find that the claims in Walsh et al. (2017) are unsupported by rigorous, or in some cases, any scientific investigation. In this correspondence, we present certain examples which we feel require further investigation by the co-authors prior to being presented in this review article. There are certain statements regarding HABs within the introduction that do not appear to be supported by the evidence presented. On occasions, the readers are directed to figures or tables for evidence which in turn lack relevant references to substantiate the claims in the text. The selfreferential approach coupled with presenting arguments by assertion give the illusion of a factual review while crucial evidence needed to support the conclusions drawn is simply not presented. The following texts from the review are used as examples, which are far from exhaustive; which we feel require relevant citations for factual correction, prior to deriving associations. "A resident of Brisbane died from ciguatera, after eating sawtooth barracuda Sphyraena punamiae in 2008 (Hamilton et al., 2010), of presumed Gambierdiscus lapillus origins (Kretzschmar et al., 2017). Before this recent event, the last recorded case of Australian ciguatera was again in Brisbane during 1967 (Clark and Whitwell)."
