Preterm infants can be successfully resuscitated with <100% oxygen (O₂); however, initiation with room air remains controversial. Current Neonatal Resuscitation Program (NRP) guidelines suggest using air or blended O₂ to titrate O₂ to meet target preductal saturation goals.

This is the first trial to compare a limited O₂ strategy to target NRP–recommended transitional goal saturations versus a high O₂ strategy in preterm infants. The limited O₂ strategy decreased integrated excess oxygen and oxidative stress and improved respiratory outcomes. (Read the full article)

Recommended management of febrile neonates (≤28 days) includes blood, urine, and cerebrospinal fluid cultures with hospital admission for antibiotic therapy. No study has reported adherence to standard recommendations in the management of febrile neonates in US pediatric emergency departments.

There is wide variation in adherence to recommended management of febrile neonates. High rates of serious infections in admitted patients but low return rates for missed infections in discharged patients suggest additional studies needed to understand variation from current recommendations.

Diabetic ketoacidosis (DKA) is a common and serious first manifestation of diabetes mellitus in children. During initial evaluation, the venous blood pH is frequently used to make the diagnosis and classify the severity of DKA.

This study demonstrates that the serum bicarbonate concentration is a simple and accurate predictor of DKA and its severity and can be used in lieu of venous pH measurement, especially in resource-poor settings where access to pH measurement is limited. (Read the full article)

Guidelines for postdischarge monitoring of hyperbilirubinemia for neonates of white descent are available from the American Academy of Pediatrics; however, such information for healthy term and late preterm Chinese neonates is lacking.

A classification model for predicting the risk of significant hyperbilirubinemia in Chinese neonates was developed that combines a transcutaneous bilirubin–based nomogram with clinical risk factors. It classified newborns into 6 risk groups, which can guide clinicians in planning appropriate follow-up strategies. (Read the full article)

QPX7728 is an ultra-broad-spectrum boronic acid beta-lactamase inhibitor with potent inhibition of key serine and metallo beta-lactamases observed in biochemical assays. Microbiological studies using characterized strains were used to provide a comprehensive characterization of the spectrum of beta-lactamase inhibition by QPX7728. The MIC of multiple IV only (ceftazidime, piperacillin, cefepime, ceftolozane and meropenem) and orally bioavailable (ceftibuten, cefpodoxime, tebipenem) antibiotics alone and in combination with QPX7728 (4 μg/ml), as well as comparator agents, were determined against the panels of laboratory strains of P. aeruginosa and K. pneumoniae expressing over 55 diverse serine and metallo beta-lactamases. QPX7728 significantly enhanced the potency of antibiotics against the strains expressing Class A extended spectrum beta-lactamases (CTX-M, SHV, TEM, VEB, PER) and carbapenemases (KPC, SME, NMC-A, BKC-1), consistent with beta-lactamase inhibition demonstrated in biochemical assays. It also inhibits both plasmidic (CMY, FOX, MIR, DHA) and chromosomally encoded (P99, PDC, ADC) Class C beta-lactamases and Class D enzymes including carbapenemases such as OXA-48 from Enterobacteriaceae and OXA enzymes from Acinetobacter baumannii (OXA-23/24/72/58). QPX7728 is also a potent inhibitor of many class B metallo beta-lactamases (NDM, VIM, CcrA1, IMP, GIM but not SPM or L1). Addition of QPX7728 (4 μg/ml) reduced the MICs in a majority of strains to the level observed for the vector alone control, indicative of complete beta-lactamase inhibition. The ultra-broad-spectrum beta-lactamase inhibition profile makes QPX7728 a viable candidate for further development.

Denver Newsroom, Apr 28, 2020 / 05:17 pm (CNA).- Archbishop Michael Miller of Vancouver has announced that he is donating to the University of British Columbia’s research toward a COVID-19 vaccine.

“May the search for COVID-19 solutions also be a moment of solidarity, of collaboration, and of growing together as a visible sign to the world of the healing and reconciliation so needed right now,” Archbishop Miller said April 27 as reported by the B.C. Catholic.

Ryan Thomas, a special advisor to the archdiocese, told CNA that Archbishop Miller wanted to express, through his donation, the Catholic Church’s support for science and medicine that contribute to the common good.

“The Church— as Pope Francis has said from the beginning of his pontificate— is called to go out, we're called to engage, not called to retreat,” Thomas told CNA.

“From a scientific standpoint, that means identifying the research that is worthy of our investment, that meets the high standards that we have to protect life,” he said.

Thomas declined to specify the amount of the donation, but said that it was in the thousands of dollars.

The global effort to develop a COVID-19 vaccine includes at least 50 other research teams, the university says, many of which in the U.S. and Canada have received government funding and are being conducted by large pharmaceutical companies.

Pro-life leaders have warned in recent months that among the many COVID-19 vaccines currently in development worldwide, in some cases researchers are using old cell lines derived from the cells of aborted babies.

It was important to Archbishop Miller, Thomas said, that the Church be seen to be promoting research into a vaccine that Catholics can support in good conscience.

A group of Evangelical Christians and Catholics in Vancouver began to rally around the idea of supporting a vaccine that corresponded to Christian ethical standards, and eventually presented the idea of supporting UBC’s research to Archbishop Miller.

Thomas said Miller made sure to inquire about whether UBC’s vaccine research makes use of aborted fetal cells, which it does not.

Dr. Wilf Jefferies, the project’s lead researcher, told CNA via email that his research team is currently in the process of validating the potency of vaccine candidates in preclinical trials, in order to assess their potential toxicity before trying them in human subjects.

The UBC lab is using immune-boosting components called adjuvants in its vaccine candidate, with the hopes of reducing the dosage of vaccine required for complete protection against the disease. In addition, Jefferies hopes that UBC’s vaccine will continue to provide protection against COVID-19 even if the virus mutates over time.

“I am heartened by the unity and kindness that is being demonstrated during this pandemic,” Jefferies told CNA.

“I think the response by the archdiocese is an affirmative and practical way to address the critical need in our society to develop a vaccine...I am sincerely humbled by the support we have received from the archdiocese and from other groups and individuals.”

So far, Jefferies’ lab has received grants from the government-funded Michael Smith Health Research Foundation and the Sullivan Urology Foundation affiliated with the University of British Columbia, as well as a number of private donations.

There are at least 1,000 clinical trials currently taking place around the world to test potential COVID-19 vaccines.

A group of pro-life leaders in a letter to the Trump administration earlier this month reiterated that development of a COVID-19 vaccine should avoid unethical links to abortion.

“No American should be forced to choose between being vaccinated against this potentially deadly virus and violating his or her conscience,” reads the April 17 letter to Dr. Stephen M. Hahn, commissioner of the U.S. Food and Drug Administration.

“Fortunately, there is no need to use ethically problematic cell lines to produce a COVID vaccine, or any vaccine, as other cell lines or processes that do not involve cells from abortions are available and are regularly being used to produce other vaccines,” it continued.

The letter’s signers include Archbishop Joseph Naumann of Kansas City in Kansas, chair of the U.S. Conference of Catholic Bishops’ Committee on Pro-Life Activities; the heads of three other bishops’ conference committees; and leaders of many other Catholic and non-Catholic groups.

The Pontifical Academy for Life has noted that Catholics have an obligation to use ethically-sourced vaccines when available, and have an obligation to speak up and request the development of new cell lines that are not derived from aborted fetuses.

The 2008 Vatican document Dignitatis personae strongly criticized aborted fetal tissue research. However, as regards common vaccines, such as those for chicken pox and measles, mumps, and rubella (MMR), that may be derived from cell lines of aborted babies, the Vatican said they could be used by parents for “grave reasons” such as danger to their children’s health.

In a 2017 document on vaccines, the academy noted a “moral obligation to guarantee the vaccination coverage necessary for the safety of others… especially the safety of more vulnerable subjects such as pregnant women and those affected by immunodeficiency who cannot be vaccinated against these diseases.”

ABSTRACT

Dimethylsulfoniopropionate (DMSP) is abundant in marine environments and an important source of reduced carbon and sulfur for marine bacteria. While both Ruegeria pomeroyi and Ruegeria lacuscaerulensis possessed genes encoding the DMSP demethylation and cleavage pathways, their responses to DMSP differed. A glucose-fed, chemostat culture of R. pomeroyi consumed 99% of the DMSP even when fed a high concentration of 5 mM. At the same time, cultures released 19% and 7.1% of the DMSP as dimethylsulfide (DMS) and methanethiol, respectively. Under the same conditions, R. lacuscaerulensis consumed only 28% of the DMSP and formed one-third of the amount of gases. To examine the pathways of sulfur and methyl C assimilation, glucose-fed chemostats of both species were fed 100 μM mixtures of unlabeled and doubly labeled [dimethyl-¹³C, ³⁴S]DMSP. Both species derived nearly all of their sulfur from DMSP despite high sulfate availability. In addition, only 33% and 50% of the methionine was biosynthesized from the direct capture of methanethiol in R. pomeroyi and R. lacuscaerulensis, respectively. The remaining methionine was biosynthesized by the random assembly of free sulfide and methyl-tetrahydrofolate derived from DMSP. Thus, although the two species possessed similar genes encoding DMSP metabolism, their growth responses were very different.

IMPORTANCE Dimethylsulfoniopropionate (DMSP) is abundant in marine environments and an important source of reduced carbon and sulfur for marine bacteria. DMSP is the precursor for the majority of atmospheric dimethylsulfide (DMS), a climatically active gas that connects the marine and terrestrial sulfur cycles. Although research into the assimilation of DMSP has been conducted for over 20 years, the fate of DMSP in microbial biomass is not well understood. In particular, the biosynthesis of methionine from DMSP has been a focal point, and it has been widely believed that most methionine was synthesized via the direct capture of methanethiol. Using an isotopic labeling strategy, we have demonstrated that the direct capture of methanethiol is not the primary pathway used for methionine biosynthesis in two Ruegeria species, a genus comprised primarily of globally abundant marine bacteria. Furthermore, although the catabolism of DMSP by these species varied greatly, the anabolic pathways were highly conserved.

The kidneys play an important role in many processes, including urine formation, water conservation, acid-base equilibrium, and elimination of waste. The anatomic and functional development of the kidney has different maturation time points in humans versus animals, with critical differences between species in maturation before and after birth. Absorption, distribution, metabolism, and excretion (ADME) of drugs vary depending on age and maturation, which will lead to differences in toxicity and efficacy. When neonate/juvenile laboratory animal studies are designed, a thorough knowledge of the differences in kidney development between newborns/children and laboratory animals is essential. The human and laboratory animal data must be combined to obtain a more complete picture of the development in the kidneys around the neonatal period and the complexity of ADME in newborns and children. This review examines the ontogeny and cross-species differences in ADME processes in the developing kidney in preterm and term laboratory animals and children. It provides an overview of insights into ADME functionality in the kidney by identifying what is currently known and which gaps still exist. Currently important renal function properties such as glomerular filtration rate, renal blood flow, and ability to concentrate are generally well known, while detailed knowledge about transporter and metabolism maturation is growing but is still lacking. Preclinical data in those properties is limited to rodents and generally covers only the expression levels of transporter or enzyme-encoding genes. More knowledge on a functional level is needed to predict the kinetics and toxicity in neonate/juvenile toxicity and efficacy studies.

Reactive oxygen and nitrogen species have been implicated in many biological processes and diseases, including immune responses, cardiovascular dysfunction, neurodegeneration, and cancer. These chemical species are short-lived in biological settings, and detecting them in these conditions and diseases requires the use of molecular probes that form stable, easily detectable, products. The chemical mechanisms and limitations of many of the currently used probes are not well-understood, hampering their effective applications. Boronates have emerged as a class of probes for the detection of nucleophilic two-electron oxidants. Here, we report the results of an oxygen-18–labeling MS study to identify the origin of oxygen atoms in the oxidation products of phenylboronate targeted to mitochondria. We demonstrate that boronate oxidation by hydrogen peroxide, peroxymonocarbonate, hypochlorite, or peroxynitrite involves the incorporation of oxygen atoms from these oxidants. We therefore conclude that boronates can be used as probes to track isotopically labeled oxidants. This suggests that the detection of specific products formed from these redox probes could enable precise identification of oxidants formed in biological systems. We discuss the implications of these results for understanding the mechanism of conversion of the boronate-based redox probes to oxidant-specific products.

Premature infants have a higher incidence of indirect hyperbilirubinemia than term infants. Management of neonatal indirect hyperbilirubinemia in late preterm and term neonates has been well addressed by recognized, consensus-based guidelines. However, the extension of these guidelines to the preterm population has been an area of uncertainty because of limited evidence. This leads to variation in clinical practice and lack of recognition of the spectrum of bilirubin-induced neurologic dysfunction (BIND) in this population. Preterm infants are metabolically immature and at higher risk for BIND at lower bilirubin levels than their term counterparts. Early use of phototherapy to eliminate BIND and minimize the need for exchange transfusion is the goal of treatment in premature neonates. Although considered relatively safe, phototherapy does have side effects, and some NICUs tend to overuse phototherapy. In this review, we describe the epidemiology and pathophysiology of BIND in preterm neonates, and discuss our approach to standardized management of indirect hyperbilirubinemia in the vulnerable preterm population. The proposed treatment charts suggest early use of phototherapy in preterm neonates with the aim of reducing exposure to high irradiance levels, minimizing the need for exchange transfusions, and preventing BIND. The charts are pragmatic and have additional curves for stopping phototherapy and escalating its intensity. Having a standardized approach would support future research and quality improvement initiatives that examine dose and duration of phototherapy exposure with relation to outcomes.

Discovery of the Breagh gas field in the Southern North Sea (SNS) has demonstrated the potential that the Lower Carboniferous (Visean, 346.7–330.9 Ma) Farne Group reservoirs have to contribute to the UK's future energy mix. New biostratigraphic correlations provide a basis to compare Asbian and Brigantian sedimentary cores from the Breagh Field and age-equivalent sediments exposed on the Northumberland Coast, which has proved critical in gaining an understanding of exploration and development opportunities. Thirteen facies associations characterize the mixed carbonate–siliciclastic system, grouped into: marine, delta front, delta shoreface, lower delta plain and upper delta plain gross depositional environments. The facies associations are interpreted as depositing in a mixed carbonate and siliciclastic fluvio-deltaic environment, and are arranged into coarsening- and cleaning-upward cycles (parasequences) bounded by flooding surfaces. Most cycles are characterized by mouth bars, distributary channels, interdistributary bays and common braided rivers, interpreted as river-dominated deltaic deposits. Some cycles include rare shoreface and tidally-influenced deposits, interpreted as river-dominated and wave- or tide-influenced deltaic deposits. The depositional processes that formed each cycle have important implications for the reservoir net/gross ratio (where this ratio indicates the proportion of sandstone beds in a cycle), thickness and lateral extent. The deltaic deposits were controlled by a combination of tectonic and eustatic (allocyclic) events and delta avulsion (autocyclic) processes, and are likely to reflect a changing tectonic regime, from extension within elongate fault-bounded basins (synrift) to passive regional thermal subsidence (post-rift). Deep incision by the Base Permian Unconformity across the Breagh Field has removed the Westphalian, Namurian and upper Visean, to leave the more prospective thicker clastic reservoirs within closure.

Addition of sodium bicarbonate (NaHCO₃) to standard antimicrobial susceptibility testing medium reveals certain methicillin-resistant Staphylococcus aureus (MRSA) strains to be highly susceptible to β-lactams. We investigated the prevalence of this phenotype (NaHCO₃ responsiveness) to two β-lactams among 58 clinical MRSA bloodstream isolates. Of note, ~75% and ~36% of isolates displayed the NaHCO₃ responsiveness phenotype to cefazolin (CFZ) and oxacillin (OXA), respectively. Neither intrinsic β-lactam MICs in standard Mueller-Hinton broth (MHB) nor population analysis profiles were predictive of this phenotype. Several genotypic markers (clonal complex 8 [CC8]; agr I and spa t008) were associated with NaHCO₃ responsiveness for OXA.

We investigated dose-fractionated polymyxin B (PB) on acute kidney injury (AKI). PB at 12 mg of drug/kg of body weight per day (once, twice, and thrice daily) was administered in rats over 72 h. The thrice-daily group demonstrated the highest KIM-1 increase (P = 0.018) versus that of the controls (P = 0.99) and histopathological damage (P = 0.013). A three-compartment model best described the data (bias, 0.129 mg/liter; imprecision, 0.729 mg²/liter²; R², 0.652,). Area under the concentration-time curve at 24 h (AUC₂₄) values were similar (P = 0.87). The thrice-daily dosing scheme resulted in the most PB-associated AKI in a rat model.
