Proprotein Convertase Subtilisin Kexin 9 Inhibitor in Severe Sepsis and Septic Shock Patients in a Phase II Prospective Cohort Study-Preliminary Results.

Sepsis is a life-threatening organ dysfunction syndrome caused by a dysregulated host response to infection that has a high mortality rate. Proprotein convertase subtilisin kexin 9 (PCSK9) is a serine protease secreted by the liver. Its binding to the low-density lipoprotein (LDL) receptor enhances its degradation, causing an increase in LDL levels in the blood.

Amikacin treatment in patients with Enterobacterales bacteraemia: impact of MIC on mortality.

Background: Recently, breakpoints of Enterobacterales to amikacin were changed from MIC ≤ 16 mg/L to MIC ≤ 4 mg/L based mainly on laboratory data with little supporting clinical evidence. Our aim was to investigate the relation between MIC of Enterobacterales to amikacin and mortality among patients with Enterobacterales bacteraemia from a urinary tract source treated with amikacin.

Patients And Methods: This retrospective, single-centre study included patients with Enterobacterales urinary source bacteraemia treated with amikacin, with Low (MIC ≤ 4 mg/L) and High (MIC 8 or 16 mg/L) MICs.

The impact of Boric Acid tubes on quantitative urinary bacterial cultures in hospitalized patients.

Introduction: The accuracy of urine culture results can be affected by pre-analytical factors such as transport delays and storage conditions. The objectives of this study were to analyze urine collection practices and assess the impact of introducing boric acid tubes for urine collection on quantitative urinary bacterial cultures of hospitalized patients in medical wards.

Methods: A quasi-experimental pre-post study conducted in an acute care facility.

Genome sequence of two novel virulent clinical strains of Burkholderia pseudomallei isolated from acute melioidosis cases imported to Israel from India and Thailand.

Objective: Burkholderia pseudomallei, the etiological cause of melioidosis, is a soil saprophyte endemic in South-East Asia, where it constitutes a public health concern of high-priority. Melioidosis cases are sporadically identified in nonendemic areas, usually associated with travelers or import of goods from endemic regions. Due to extensive intercontinental traveling and the anticipated climate change-associated alterations of the soil bacterial flora, there is an increasing concern for inadvertent establishment of novel endemic areas, which may expand the global burden of melioidosis.

Blood stream Infections in chronic hemodialysis patients - characteristics and outcomes.

Introduction: Bloodstream Infections (BSI) are a major cause of death and hospitalization among hemodialysis (HD) patients. The rates of BSI among HD patients vary and are influenced by local patient and pathogen characteristics. Modifications in local infection prevention protocols in light of active surveillance of BSI has been shown to improve clinical outcomes.

A Randomized Controlled Study Assessing Convalescent Immunoglobulins vs Convalescent Plasma for Hospitalized Patients With Coronavirus 2019.

Background: It is unknown whether convalescent immunoglobulins (cIgGs) are better than convalescent plasma (CP) for patients with coronavirus 2019 (COVID-19).

Methods: In this randomized controlled trial, we assigned high risk COVID-19 patients with ≤10 days of symptoms, to receive cIgGs or CP. The primary endpoint was improvement on day 14 according to the World Health Organization scale.

Short- and long-term mortality in patients with urosepsis caused by Escherichia coli susceptible and resistant to 3rd generation cephalosporins.

Background: The aim of this study was to compare short- and long-term mortality among patients with urosepsis caused by Escherichia coli susceptibile (EC-SC) and resistant (EC-RC) to 3rd generation cephalosporins.

Methods: A retrospective cohort study that included all patients with E. coli urosepsis admitted to a 700-bed hospital from January 2014 until December 2019.

Assessing modified aluminum-based water treatment residuals as a plant-available phosphorus source.

Inorganic phosphorus (P) fertilizers are a finite resource; alternative means of creating P fertilizers from current municipal and agricultural waste sources may reduce our reliance on phosphate rock mining, and improve waste disposal and nutrient cycling. Previous research demonstrated that organic aluminum water treatment residual composites (Al/O-WTR), created by mixing aluminum water treatment residuals (Al-WTR) with swine wastewater, have the potential to be a source of plant-available P. A greenhouse study was conducted to compare spring wheat (Triticum aestivum L.

Aminoglycoside versus carbapenem or piperacillin/tazobactam treatment for bloodstream infections of urinary source caused by Gram-negative ESBL-producing Enterobacteriaceae.

Objectives: We studied the performance of aminoglycosides in treating bloodstream infections (BSIs) of urinary source caused by ESBL-producing Enterobacteriaceae (ESBL-EB).

Methods: In a retrospective study of 193 patients with a clinical diagnosis of urinary tract infection, pyelonephritis or urosepsis and blood and urine cultures positive for ESBL-EB, patients were grouped according to whether they were treated with an aminoglycoside, a carbapenem or piperacillin/tazobactam. Multivariate analysis was used to define risk factors for mortality with inverse probability of treatment weighting used to minimize confounding.

Phosphorus Sorption to Aluminum-based Water Treatment Residuals Reacted with Dairy Wastewater: 2. X-Ray Absorption Spectroscopy.

Phosphorus capture from wastewater can decrease water pollution and provide a P-rich fertilizer alternative for use in agricultural production. This study was conducted to elucidate P retention mechanisms in Al-based water treatment residuals (Al-WTR) to gain insight regarding P sorption and the potential for P release from Al-WTR after reaction with dairy wastewater. Synchrotron-based microfocused X-ray fluorescence (micro-XRF) spectrometry, bulk P -edge X-ray absorption near edge structure spectroscopy (XANES), and P -edge micro-XANES spectroscopy were used to determine P distribution and speciation within the Al-WTR materials.

Phosphorus Sorption Characteristics in Aluminum-based Water Treatment Residuals Reacted with Dairy Wastewater: 1. Isotherms, XRD, and SEM-EDS Analysis.

We examined P sorption characteristics in Al-based water treatment residuals (Al-WTR) generated from slightly alkaline surface water and in an organic residual composite (WW-Al/O-WTR), produced by using the Al-WTR to treat organic-rich and high P concentration dairy wastewater. Solids from both residuals were examined using scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) and X-ray diffraction (XRD), and exposed to P additions of 0 to 4000 mg L in a sorption experiment. The Al-WTR removed ∼97% of the added P, whereas WW-Al/O-WTR removed only 78% of the added P in the addition range of 0 to 100 mg P L.

Gram-negative bloodstream infections in hemodialysis patients: A retrospective study .

Background: Bloodstream infections (BSIs) are an important cause of hospitalizations and mortality among hemodialysis (HD) patients. Epidemiology of these infections is changing, with increasing rates of Gram-negative pathogens, including resistant ones. Few studies have focused on the characteristics and outcomes of these infections.

Infants Born with Esophageal Atresia with or without Tracheo-Esophageal Fistula: Short- and Long-Term Outcomes.

Background: The estimated incidence of esophageal atresia (EA) with or without tracheo-esophageal fistula (TEF) is 1:3500 live births. During childhood these patients have various co-morbidities, but the overall quality of life among adults is similar to that of the general population.

Objectives: To evaluate short- and long-term co-morbidities and quality of life among infants born with EA ± TEF at a large single medical center.

Innovative approach for recycling phosphorous from agro-wastewaters using water treatment residuals (WTR).

Phosphorus capture from polluting streams and its re-use using industrial byproducts has the potential to also reduce environmental threats. An innovative approach was developed for P removal from soil leachate and dairy wastewater using Al-based water treatment residuals (Al-WTR) to create an organic-Al-WTR composite (Al/O-WTR), potentially capable of serving as a P fertilizer source. Al-WTR was mixed with either soil leachate, or with dairy wastewater, both of which contained elevated P concentrations (e.

Method for the analysis of oxygen isotopic composition of soil phosphate fractions.

The isotopic signature of oxygen in phosphate (δ(18)O(P)) of various soil fractions may shed light on P transformations, including phosphorus (P) recycling by soil microorganisms, uptake by plants and P adsorption, precipitation and release by oxides and minerals, thus increasing our understanding on P cycling and lability in soils. We developed and tested a protocol to extract and purify inorganic phosphate (Pi) from different soil fractions distinguished by binding strength and precipitate it as silver phosphate (Ag(3)PO(4)) for δ(18)O(P) analysis. Soil P is extracted sequentially using water, NaHCO(3), NaOH and HCl and Pi in each solution is purified and precipitated as Ag(3)PO(4).
