Furthermore, typhoon had adeptly uniformed the plastisphere community in the sediment along the 190 km costal line overnight. A significant increase of nitrogen fixer, Bradyrhizobiaceae, was observed ubiquitously after typhoon, which might alter the nitrogen cycling and increase eutrophic condition of the coastal ecological system. Together, this study expanded the knowledge about the impact of typhoon-induced influx of the microplastics on coastal biogeochemical cycling. Moreover, the microplastics and the plastisphere compositional pattern revealed here will underpin future studies on adsorption behavior, interfacial processes and ecotoxicity of the coastal microplastic pollution.As(III) species are the predominant form of arsenic found in groundwater. However, nanofiltration (NF) and reverse osmosis (RO) membranes are often unable to effectively reject As(III). In this study, we fabricate highly conducting ultrafiltration (UF) membranes for effective As(III) rejection. These membranes consist of a hydrophilic nickel-carbon nanotubes layer deposited on a UF support, and used as cathodes. Applying cathodic potentials significantly increased As(III) rejection in synthetic/real tap water, a result of locally elevated pH that is brought upon through water electrolysis at the membrane/water interface. The elevated pH conditions convert H3ASO3 to H2AsO3-/HAsO32- that are rejected by the negatively charged membranes. Ipatasertib concentration In addition, it was found that Mg(OH)2 that precipitates on the membrane can further trap arsenic. Importantly, almost all As(III) passing through the membranes is oxidized to As(V) by hydrogen peroxide produced on the cathode, which significantly decreased its overall toxicity and mobility. Although the high pH along the membrane surface led to mineral scaling, this scale could be partially removed by backwashing the membrane. To the best of our knowledge, this is the first report of effective As(III) removal using low-pressure membranes, with As(III) rejection higher than that achieved by NF and RO, and high water permeance.
Accurate information concerning implanted medical devices prior to a Magnetic resonance imaging (MRI) examination is crucial to assure safety of the patient and to address MRI induced unintended changes in device settings. The identification of these devices still remains a very challenging task. In this paper, with the aim of providing a faster device detection, we propose the adoption of deep learning for medical device detection from X-rays.

In particular, we propose a pipeline for the identification of implanted programmable cerebrospinal fluid shunt valves using X-ray images of the radiologist workstation screens captured with mobile phone integrated cameras at different angles and illuminations. We compare the proposed convolutional neural network with published methods.

Experimental results show that this approach outperforms methods trained on images digitally transferred directly from the scanners and then applied on mobile phones images (mean accuracy 95%vs 77%, Avg. Precision 0.96vs 0.77, Avgy scanners or clinical picture archiving and communication system (PACS) in terms of ease of integration in the hospital or clinical ecosystems.
Our goal is to provide an overall strategy for utilizing continuous accelerated life models in the discrete setting that provides a unique and flexible modeling approach across a variety of hazard shapes.

We convert well-known continuous accelerated life distributions into their discrete counterpart and show theoretically that the existing software that currently exists to accommodate, left, right and interval censoring in the continuous case is re-usable in the discrete setting due to the structure of the likelihood equations.

We demonstrate across a variety of simulated and real-world data that our modeling approach can accommodate discrete data that may either be approximately symmetric, left-skewed or right skewed, overcoming the limitations of more traditional modeling approaches.

We illustrate both theoretically and through simulations that our approach for accommodating discrete failure time and count data is quite flexible. We demonstrate that the special case of the discrete Weibull model readily can accommodate truly Poisson distributed data and has a great degree of flexibility for non-Poisson distributed data.

Eighteen pigs were assigned to two experimental treatments and fed a cereal-based concentrate diet (control) or the same diet in which ensiled bergamot pulp replaced 15% dry matter of the diet fed (BP). The BP treatment increased α-linolenic acid (+250%; P less then 0.05), docosapentaenoic acid (+62%; P less then 0.05), docosahexaenoic acid (+43%; P less then 0.05) and consequently n-3 PUFA (+15%; P less then 0.01) in meat. In salami, the content of α-linolenic acid, total PUFA and n-3 PUFA increased (+320%, +25% and + 258%, respectively) by feeding the BP diet (P less then 0.001). The inclusion of bergamot pulp in the diet did not alter the oxidative stability in raw and cooked meat and colour descriptors. In salami, TBARS values were lower after 5 days of storage (P less then 0.001) in BP group (1.54 vs 2.96). Finally, dietary supplementation with ensiled bergamot pulp to pigs improved the nutritional value of meat and meat products.The development of novel therapeutics is associated with high rates of attrition, with unexpected adverse events being a major cause of failure. Serious adverse events have led to organ failure, cancer development and deaths that were not expected outcomes in clinical trials. These life-threatening events were not identified during therapeutic development due to the lack of preclinical safety tests that faithfully represented human physiology. We highlight the successful application of several novel technologies, including high-throughput screening, organs-on-chips, microbiome-containing drug-testing platforms and humanised mouse models, for mechanistic studies and prediction of toxicity. We propose the incorporation of similar preclinical tests into future drug development to reduce the likelihood of hazardous therapeutics entering later-stage clinical trials.Using daily vital statistics data from the Japanese Ministry of Health, Labour and Welfare, we provide the first weekly and age-group-specific estimates of the additional suicide burden during the COVID-19 pandemic in Japan by gender, from January through November 2020. Our results indicate that compared with the previous five years, suicide cases in 2020 in Japan have increased from late July to November for women in all age groups and for men in the 20-29 and 80+ years age group. Targeted interventions based on age and gender might be more effective in reducing suicide during the COVID-19 pandemic in Japan.
We compared the effectiveness of cefazolin and cloxacillin as definitive antibiotic therapy for methicillin-susceptible Staphylococcus aureus (MSSA) spinal epidural abscess (SEA).

This retrospective cohort study included patients with MSSA SEA from two academic hospitals in Hamilton, Ontario, Canada, between 2014 and 2020. Patients treated with cefazolin were compared to those treated with cloxacillin. Co-primary outcomes included 90-day mortality, antibiotic failure, adverse reactions and recurrence. Inverse probability of treatment weighting using propensity scores was used to balance important prognostic factors and to estimate an adjusted risk difference.

Of 98 patients with MSSA SEA, 50 and 48 patients were treated with cefazolin and cloxacillin, respectively. Mortality at 90 days was 8% and 13% in the cefazolin and cloxacillin groups, respectively (P=0.52). The antibiotic failure rate was 12% and 19% in the cefazolin and cloxacillin groups, respectively (P=0.41). The serious adverse reactions rate was 0% and 4% in the cefazolin and cloxacillin groups, respectively (P=0.24). The recurrence rate was 2% and 8% in the cefazolin and cloxacillin groups, respectively (P=0.20). The adjusted risk difference for mortality at 90 days was -1% [95% confidence interval (CI) -10% to 8%] favouring cefazolin. The adjusted risk differences for antibiotic failure, adverse reactions and recurrence were 1% (95% CI -12% to 14%), -5% (95% CI -11% to 2%) and -18% (-36% to -1%) respectively.

Cefazolin is likely as effective as an antistaphylococcal penicillin and may be considered as a first-line treatment for MSSA SEA.

Understanding how incentives and their timing influence study enrollment rates is important to efficient study design and increasing the generalizability of findings. This 2-arm, parallel randomized trial evaluated how conditional versus unconditional mailed incentives of a $20 gift card affected study enrollment in a sample of participants screened for lung cancer screening.

Eligible participants included Black and White adults who underwent lung cancer screening with low-dose CT and had negative screening results at two North Carolina imaging facilities in 2018. We used a stratified randomization scheme, by sex and race, to assign incentive type (conditional vs. unconditional). We used the Tailored Design Method with six points of mailed contact to engage participants. We compared study enrollment rates using chi-square tests and logistic regression analyses.

After adjusting for sex, race, age, smoking status, participant residence, and screening site, participants who received unconditional incentives were 74% more likely to enroll than those who received conditional incentives (adjusted OR= 1.74 (95% CI 1.01, 3.00).

Type of incentive can play a role in increasing study enrollment, especially mailed surveys that target individuals who currently or previously smoked. Unconditional incentives may be worth the initial cost to engage study participants.

This study aims to evaluate whether mitral valve replacement in the elderly is associated with similar outcome compared to repair in the short- and long-term. All patients aged 70 years and older undergoing minimally invasive mitral valve surgery were studied retrospectively. Primary outcome was 30-day complication rate, secondary outcome was long-term survival and freedom from re-operation. 223 Patients underwent surgery (124 replacement and 99 repair) with a mean age of 76.4 ± 4.2 years. 30-Day complication rate (replacement 73.4% versus repair 67.7%; p=0.433), 30-day mortality (replacement 4.0% versus repair 1.0%; p=0.332) and 30-day stroke rate (replacement 0.0% versus repair 1.0%; p=0.910) were similar in both groups. Multivariable cox regression revealed higher age, diabetes and left ventricular dysfunction as predictors for reduced long-term survival, while a valve replacement was no predictor for reduced survival.
