5%) died by 28 days after diagnosis. Specific underlying comorbidities (age >65 [aOR 3.0, 95%CI 1.7-5.5, p<0.001], congestive heart failure [aOR 3.2, 95%CI 1.4-7.0, p=0.004], chronic lung disease [aOR 2.5, 95%CI 1.2-5.2, p=0.018], obesity [aOR 1.9, 95% CI 1.0-3.4, p=0.039]) and presenting findings (lymphopenia [aOR 1.9, 95%CI 1.1-3.5, p=0.033], abnormal chest imaging [aOR 2.9, 95%CI 1.1-7.5, p=0.027]) were independently associated with mortality. Multiple measures of immunosuppression intensity were not associated with mortality.

Mortality among SOT recipients hospitalized for COVID-19 was 20.5%. Age and underlying comorbidities rather than immunosuppression intensity-related measures were major drivers of mortality.

Ribbon is an alignment visualization tool that shows how alignments are positioned within both the reference and read contexts, giving an intuitive view that enables a better understanding of structural variants and the read evidence supporting them. Ribbon was born out of a need to curate complex structural variant calls and determine whether each was well supported by long-read evidence, and it uses the same intuitive visualization method to shed light on contig alignments from genome-to-genome comparisons.

Ribbon is freely available online at http//genomeribbon.com/ and is open-source at https//github.com/marianattestad/ribbon.

Rapid increase of the data size in metagenome researches has raised the demand for new tools to process large datasets efficiently. In order to accelerate the metagenome profiling process in the scenario of big data, we developed SOAPMetaS, a marker gene-based multiple-sample metagenome profiling tool built on Apache Spark. SOAPMetaS demonstrates high performance and scalability to process large datasets. It can process 80 samples of FASTQ data, summing up to 416 GiB, in around half an hour; and the accuracy of species profiling results of SOAPMetaS is similar to that of MetaPhlAn2. SOAPMetaS can deal with a large volume of metagenome data more efficiently than common-used single-machine tools.

Plasma chemokines are biomarkers of greater disease severity, higher bacterial burden and delayed sputum culture conversion in pulmonary tuberculosis (PTB). Whether plasma chemokines could also serve as biomarkers of unfavorable treatment outcomes in PTB is not known.

A cohort of newly diagnosed, sputum smear and culture positive adult individuals with drug-sensitive PTB were recruited under the Effect of diabetes on Tuberculosis Severity study in Chennai, India. Plasma chemokine levels measured before treatment initiation were compared between 68 cases with unfavorable outcomes (treatment failure, death or recurrence) and 136 control individuals who had recurrence-free cure. VLS-1488 manufacturer A second validation cohort comprising of newly diagnosed, culture positive adults with drug-sensitive TB was used to measure plasma chemokine levels in 20 cases and 40 controls.

Six chemokines (CCL2, CCL3, CCL4, CXCL8, CXCL10 and CX3CL1) were associated with increased risk, while CXCL1 was associated with decreased risk of unfavorable outcomes in unadjusted and adjusted analyses in the test cohort. Similarly, CCL3, CXCL8 and CXCL10 were associated with increased risk of unfavorable treatment outcomes in the validation cohort. Receiver operating characteristic analysis revealed combinations of CCL3, CXCL8 and CXCL10 exhibited very high sensitivity and specificity in differentiating cases versus controls.

Our study reveals a plasma chemokine signature that can be used as a novel biomarker for predicting adverse treatment outcomes in PTB.

Protein carbonylation is one of the most important oxidative stress-induced post-translational modifications (PTMs), which is generally characterized as stability, irreversibility and relative early formation. It plays significant role in orchestrating various biological processes and has been already demonstrated to be related to many diseases. However, the experimental technologies for carbonylation sites identification are not only costly and time-consuming, but also unable of processing a large number of proteins at a time. Thus, rapidly and effectively identifying carbonylation sites by computational methods will provide key clues for the analysis of occurrence and development of diseases.

In this study, we developed a predictor called iCarPS to identify carbonylation sites based on sequence information. A novel feature encoding scheme called residues conical coordinates combined with their physicochemical properties was proposed to formulate carbonylated protein and non-carbonylated protein samples. To remove potential redundant features and improve the prediction performance, a feature selection technique was utilized. The accuracy and robustness of iCarPS were proved by experiments on training and independent datasets. Comparison with other published methods demonstrated that the proposed method is powerful and could provide powerful performance for carbonylation sites identification.

Based on the proposed model, a user-friendly webserver and a software package were constructed, which can be freely accessed at http//lin-group.cn/server/iCarPS.

Rapid developments in sequencing technologies have boosted generating high volumes of sequence data. To archive and analyze those data, one primary step is sequence comparison. Alignment-free sequence comparison based on k-mer frequencies offers a computationally efficient solution, yet in practice, the k-mer frequency vectors for large k of practical interest lead to excessive memory and storage consumption.

We report CRAFT, a general genomic/metagenomic search engine to learn compact representations of sequences and perform fast comparison between DNA sequences. Specifically, given genome or high throughput sequencing (HTS) data as input, CRAFT maps the data into a much smaller embedding space and locates the best matching genome in the archived massive sequence repositories. With 102 - 104-fold reduction of storage space, CRAFT performs fast query for gigabytes of data within seconds or minutes, achieving comparable performance as six state-of-the-art alignment-free measures.

This prospective, randomized, and double-blinded trial evaluates the effect of intraoperative glenohumeral joint lavage in open reduction and internal fixation of displaced intracapsular proximal humeral fractures.

Between January 2016 and April 2018, 86 patients (mean age 65.2 ± 16.3 years) with a displaced intracapsular proximal humeral fracture were treated by open reduction and internal fixation using locking plates. Patients were randomized to either locked plating followed by intraoperatively performed glenohumeral joint lavage (group L, n = 36) or locked plating without the lavage (group NL, n = 36). Functional outcome assessment included range of shoulder motion, strength, and the Constant score, obtained 6 weeks, 3 months, 6 months, and 12 months postoperatively. A total of 62 shoulders could be reviewed for final investigation (86% follow-up).

One year after open reduction and internal fixation, the mean Constant score was 70 ± 14 (group L, n = 31) compared with 73 ± 14 (group NL, n = 31, P = at 1-year follow-up.
It has been reported that the addition of dexamethasone to interscalene brachial plexus block (ISBPB) prolongs the duration of the block effect. However, there have been no studies focusing on the effects of dexamethasone on rebound pain after the block effect has worn off. The aim of this study was to investigate the effect on postoperative pain when dexamethasone was added to ISBPB for arthroscopic rotator cuff repair (ARCR).

In this multicenter, single-blinded, and randomized controlled study, 54 patients (33 males, 21 females) who received ARCR were randomly assigned to group L (ISBPB with 20 cc of 0.25% levobupivacaine; 21 patients) or group LD (ISBPB with 20 cc of 0.25% levobupivacaine + 3.3 mg dexamethasone; 33 patients). The primary outcome was the visual analog scale (VAS) for pain after the block effect had worn off. Secondary outcomes were the duration of analgesia, the time to the first request for additional analgesic, the number of additional doses of analgesic, and complications.

The VAS scores on postoperative days 0 and 1 were significantly lower in group LD than group L (P = .005, .035). This indicated that the rebound pain was relieved in group LD. After postoperative day 1, there was no significant difference in VAS score (P = .43 and .19 for days 2 and 3, respectively). The duration of analgesia was significantly longer in group LD than group L (P < .001). JNJ-64264681 price The time to the first request for additional analgesic was significantly longer in group LD than group L (P < .001). The number of additional doses of analgesic was significantly lower in group LD (P < .001).

In ARCR, the addition of dexamethasone to levobupivacaine not only prolongs the duration of ISBPB but also relieves rebound pain after the block effect wears off.

With the recent opioid epidemic in the United States, measures by both government and medical providers are being taken to decrease the opioid dependence rate. Different methods have been proposed, including patient education and multimodal pain therapies. The purpose of this study was to determine whether preoperative opioid education reduces the risk of opioid dependence at 2 yearsfollowing arthroscopic rotator cuff repair (ARCR).

This study was a 2-year follow-up of the 2018 Neer Award study that demonstrated the use of preoperative opioid education as a means to reduce postoperative opioid consumption after ARCR at 3-month follow-up. This was a prospective, single-center, single-blinded, parallel-group, 2-arm, randomized clinical trial with a 11 allocation ratio. To study the effect of preoperative opioid education on opioid dependence at 2 years, we randomized patients into 2 cohorts, a study cohort and a control cohort. Data were obtained with a review of prescription data-monitoring software and a patients undergoing ARCR.
Our study found that patients who were preoperatively educated on opioid use were less likely to become opioid dependent at 2-year follow-up. Therefore, we demonstrated that opioid education does impart significant long-term benefits to patients undergoing ARCR.The taxonomic positions of two novel aerobic, Gram-stain-positive Actinobacteria, designated RB20T and RB56T, were determined using a polyphasic approach. Both were isolated from the fungus-farming termite Macrotermes natalensis. Results of 16S rRNA gene sequence analysis revealed that both strains are members of the genus Nocardia with the closest phylogenetic neighbours Nocardia miyunensis JCM12860T (98.9 %) and Nocardia nova DSM44481T (98.5 %) for RB20T and Nocardia takedensis DSM 44801T (98.3 %), Nocardia pseudobrasiliensis DSM 44290T (98.3 %) and Nocardia rayongensis JCM 19832T (98.2 %) for RB56T. Digital DNA-DNA hybridization (DDH) between RB20T and N. miyunensis JCM12860T and N. nova DSM 44481T resulted in similarity values of 33.9 and 22.0 %, respectively. DDH between RB56T and N. takedensis DSM44801T and N. pseudobrasiliensis DSM44290T showed similarity values of 20.7 and 22.3 %, respectively. In addition, wet-lab DDH between RB56T and N. rayongensis JCM19832T resulted in 10.2 % (14.5 %) similarity. Both strains showed morphological and chemotaxonomic features typical for the genus Nocardia, such as the presence of meso-diaminopimelic acid (A2pm) within the cell wall, arabinose and galactose as major sugar components within whole cell-wall hydrolysates, the presence of mycolic acids and major phospholipids (diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol), and the predominant menaquinone MK-8 (H4, ω-cyclo). The main fatty acids for both strains were hexadecanoic acid (C16 0), 10-methyloctadecanoic acid (10-methyl C18 0) and cis-9-octadecenoic acid (C18 1 ω9c). We propose two novel species within the genus Nocardia Nocardia macrotermitis sp. nov. with the type strain RB20T (=VKM Ac-2841T=NRRL B65541T) and Nocardia aurantia sp. nov. with the type strain RB56T (=VKM Ac-2842T=NRRL B65542T).JNJ-64264681 price

A recent study reported on an in-silico imaging trial that evaluated the performance of digital breast tomosynthesis (DBT) as a replacement for full-field digital mammography (FFDM) for breast cancer screening. In this in-silico trial, the whole imaging chain was simulated, including the breast phantom generation, the x-ray transport process, and computational readers for image interpretation. We focus on the design and performance characteristics of the computational reader in the above-mentioned trial. Location-known lesion (spiculated mass and clustered microcalcifications) detection tasks were used to evaluate the imaging system performance. The computational readers were designed based on the mechanism of a channelized Hotelling observer (CHO), and the reader models were selected to trend human performance. Parameters were tuned to ensure stable lesion detectability. A convolutional CHO that can adapt a round channel function to irregular lesion shapes was compared with the original CHO and was found to parison of breast imaging systems. © 2020 Society of Photo-Optical Instrumentation Engineers (SPIE).Purpose Bayesian theory provides a sound framework for ultralow-dose computed tomography (ULdCT) image reconstruction with two terms for modeling the data statistical property and incorporating a priori knowledge for the image that is to be reconstructed. We investigate the feasibility of using a machine learning (ML) strategy, particularly the convolutional neural network (CNN), to construct a tissue-specific texture prior from previous full-dose computed tomography. Approach Our study constructs four tissue-specific texture priors, corresponding with lung, bone, fat, and muscle, and integrates the prior with the prelog shift Poisson (SP) data property for Bayesian reconstruction of ULdCT images. The Bayesian reconstruction was implemented by an algorithm called SP-CNN-T and compared with our previous Markov random field (MRF)-based tissue-specific texture prior algorithm called SP-MRF-T. Results In addition to conventional quantitative measures, mean squared error and peak signal-to-noise ratio, structure similarity index, feature similarity, and texture Haralick features were used to measure the performance difference between SP-CNN-T and SP-MRF-T algorithms in terms of the structure and tissue texture preservation, demonstrating the feasibility and the potential of the investigated ML approach. Conclusions Both training performance and image reconstruction results showed the feasibility of constructing CNN texture prior model and the potential of improving the structure preservation of the nodule comparing to our previous regional tissue-specific MRF texture prior model. © 2020 Society of Photo-Optical Instrumentation Engineers (SPIE).Alzheimer's disease (AD) is characterized by the progressive accumulation of neurofibrillary tangles associated with amyloid plaques. We used 80 resting-state functional magnetic resonance imaging and 80 T 1 images acquired using MP-RAGE (magnetization-prepared rapid acquisition gradient echo) from Alzheimer's Disease Neuroimaging Initiative data to detect atrophy changes and functional connectivity patterns of the default mode networks (DMNs). The study subjects were classified into four groups (each with n = 20 ) based on their Mini-Mental State Examination (MMSE) score as follows cognitively normal (CN), early mild cognitive impairment, late mild cognitive impairment, and AD. The resting-state functional connectivity of the DMN was examined between the groups using the CONN functional connectivity toolbox. Loss of gray matter in AD was observed. Atrophy measured by the volume of selected subcortical regions, using the Functional Magnetic Resonance Imaging of the Brain (FMRIB) Software Library's Integrated Registration and Segmentation Tool (FIRST), revealed significant volume loss in AD when compared to CN ( p 0.9 ), compared to morphometric changes ( A Z less then 0.8 ). In summary, it is observed that the functional connectivity measures may serve a better predictor in comparison to structural atrophy changes. We postulate that functional connectivity measures have the potential to evolve as a marker for the early detection of AD. © 2020 Society of Photo-Optical Instrumentation Engineers (SPIE).Purpose We describe a shape-aware multisurface simplex deformable model for the segmentation of healthy as well as pathological lumbar spine in medical image data. Approach This model provides an accurate and robust segmentation scheme for the identification of intervertebral disc pathologies to enable the minimally supervised planning and patient-specific simulation of spine surgery, in a manner that combines multisurface and shape statistics-based variants of the deformable simplex model. Statistical shape variation within the dataset has been captured by application of principal component analysis and incorporated during the segmentation process to refine results. In the case where shape statistics hinder detection of the pathological region, user assistance is allowed to disable the prior shape influence during deformation. Results Results demonstrate validation against user-assisted expert segmentation, showing excellent boundary agreement and prevention of spatial overlap between neighboring surfaces. This section also plots the characteristics of the statistical shape model, such as compactness, generalizability and specificity, as a function of the number of modes used to represent the family of shapes. Final results demonstrate a proof-of-concept deformation application based on the open-source surgery simulation Simulation Open Framework Architecture toolkit. Conclusions To summarize, we present a deformable multisurface model that embeds a shape statistics force, with applications to surgery planning and simulation. © 2020 Society of Photo-Optical Instrumentation Engineers (SPIE).Purpose While radiomics feature values can differ when extracted using different radiomics software, the effects of these variations when applied to a particular clinical task are currently unknown. The goal of our study was to use various radiomics software packages to classify patients with radiation pneumonitis (RP) and to quantify the variation in classification ability among packages. Approach A database of serial thoracic computed tomography scans was obtained from 105 patients with esophageal cancer. Patients were treated with radiation therapy (RT), resulting in 20 patients developing RP grade ≥ 2 . find more Regions of interest (ROIs) were randomly placed in the lung volume of the pre-RT scan within high-dose regions ( ≥ 30 Gy ), and corresponding ROIs were anatomically matched in the post-RT scan. Three radiomics packages were compared A1 (in-house), IBEX v1.0 beta, and PyRadiomics v.2.0.0. Radiomics features robust to deformable registration and common among radiomics packages were calculated four first-order and four gray-level co-occurrence matrix features.find more

ere is a close relationship between dementia and malnutrition. Clinical approaches to minimize malnutrition in persons with dementia should include regular screening for malnutrition and its risk factors, avoidance of dietary restrictions, and support of persons at risk for malnutrition with oral nutritional supplements. Moreover, the influence of nutritional status varies in different types of dementia. Nutritional status may be worse in DLB and VaD compared with other types of dementia, whereas nutritional status in FTD is less.
Physical activity is associated with improvement in overall health and well-being, but robust evidence with comprehensive assessment of general health is lacking. This study aimed to clarify the effects of physical activity on intrinsic capacity among community-dwelling older adults with subjective memory concerns.

A single-blind randomized controlled trial compared aerobic training (AT), resistance training (RT), and combined training (AT+RT) programs for improving general health evaluated by intrinsic capacity.

Toyota, Japan.

Residents (65-85years old) who screened positive for subjective memory concerns using the Kihon checklist were invited for eligibility assessment. In total, 415 community-dwelling older adults were enrolled and randomized into the AT, RT, AT+RT, and control groups.

Participants in the intervention groups underwent a group training program and self-paced home training for 26weeks. TEW-7197 chemical structure The control group received lectures about health promotion. Intrinsic capacity (IC), constructed s.
Twenty-six-week AT with self-paced home training and RT with self-paced home training improve IC among community-dwelling older adults with subjective memory concerns, but the benefits waned subsequently. It will be required to develop optimal interventions that have a continuous beneficial effect on IC among community-dwelling older adults.
To examine the incremental value of sarcopenia components, following the diagnosis algorithm of the Asian consensus, on predicting adverse outcomes.

A prospective cohort study.

Four thousand community-dwelling Chinese adults (2000 men) aged 65years or older in Hong Kong (mean age=72.5 ± 5.2).

SARC-F was used as the initial predictor of 9 adverse outcomes. In step 2, muscle strength (ie, grip strength) and/or functions (ie, chair-stand, walking speed) were added on top of SARC-F. In step 3, height-, weight-, and body mass index-adjusted appendicular skeletal mass (ASM) measured by dual-energy x-ray absorptiometry (DXA) were added separately to all models formulated in step 2. The areas under the receiver operating characteristic curve (AUCs) were calculated for the models formulated in all steps. Each cumulative AUC would be compared with the AUC yielded in the previous step to evaluate the incremental prediction value.

On top of SARC-F, assessing grip strength, walking speed, or 5-time chair-stand sn provides additional power to predict adverse outcomes on top of SARC-F. Further assessment of muscle mass with DXA provides no extra constructive value ito bettering the prediction regardless of the adjustment parameters. Alternative technologies to measure muscle mass might be required.
To examine the factors of advance directive (AD) completion among older Chinese Americans.

Cross-sectional survey.

Data came from 435 Chinese Americans aged 55years and older living in 2 metropolitan areas through self-administered questionnaires and research assistant-administered interviews in 2018. Participants' average age was 75years (standard deviation=9.4).

Logistic regression was used to examine factors associated with AD completion.

Approximately 14% of participants completed an AD. Older age [odds ratio (OR) 1.07, 95% confidence interval (CI) 1.02-1.12], higher level of acculturation (OR 2.15, 95% CI 1.39-3.33), higher expectation for intergenerational support (OR 1.52, 95% CI 1.02-2.27), and having US citizenship (OR 3.02, 95% CI 1.26-7.23) were positively associated with AD completion. Physical and mental health needs were not significantly associated with AD completion.

This study is among the first focusing on AD completion among Chinese Americans, one of the fastest-growing older minority populations in the United States. Findings highlight the influence of socioeconomic and cultural factors on AD completion and illustrate the importance of developing culturally sensitive interventions to promote end-of-life care decision making among older Chinese Americans.

To study the association between antipsychotic drug treatment and hip fracture, before and after the initiation of treatment.

Nationwide cohort study.

In this study based on several Swedish registers, all individuals age ≥65years who filled prescriptions for antipsychotic drugs in 2007-2017 were matched 11 by sex and age with controls, resulting in a cohort of 255,274 individuals.

Associations between antipsychotic drug treatment and hip fracture were investigated using multivariable conditional logistic regression models and flexible parametric survival models for nonproportional hazards, starting 1year before the first prescription was filled and extending to 1year thereafter.

The studied cohort had a mean age of 81.5 (standard deviation, 8.1) years; 152,890 (59.9%) individuals were women. Antipsychotic drug use was associated with an increased risk of hip fracture in all studied time frames, before and after the initiation of treatment. The risk was highest 16-30days before the initiation of treatment (odds ratio 9.09; 95% confidence interval 7.00-11.81). The pattern was consistent in subgroup analyses of users of conventional and atypical antipsychotics, men and women, as well as in younger old and older old participants. The association with hip fracture was not influenced by antipsychotic drug dose.

The association between antipsychotic drug use and the risk of hip fracture was observed before the initiation of antipsychotic treatment. This finding suggests that factors other than exposure to antipsychotic drugs are responsible for the increased risk of hip fracture in the treatment group.
