Abstract

Pseudomonas aeruginosa (Pa), a WHO priority 1 pathogen, resulted in approximately 559,000 deaths globally in 2019. Pa has a multitude of host-immune evasion strategies that enhance Pa virulence. Most clinical isolates of Pa are infected by a phage called Pf that has the ability to misdirect the host-immune response and provide structural integrity to biofilms. Previous studies demonstrate that vaccination against the coat protein (CoaB) of Pf4 virions can assist in the clearance of Pa from the dorsal wound model in mice. Here, a consensus peptide was derived from CoaB and conjugated to cross-reacting material 197 (CRM197). This conjugate was adjuvanted with a novel synthetic Toll-like receptor agonist (TLR) 4 agonist, INI-2002, and used to vaccinate mice. Mice vaccinated with CoaB-CRM conjugate and INI-2002 developed high anti-CoaB peptide-specific IgG antibody titers. Direct binding of the peptide-specific antibodies to whole-phage virus particles was demonstrated by ELISA. Furthermore, a functional assay demonstrated that antibodies generated from vaccinated mice disrupted the replicative cycle of Pf phages. The use of an adjuvanted phage vaccine targeting Pa is an innovative vaccine strategy with the potential to become a new tool targeting multi-drug-resistant Pa infections in high-risk populations.

Abstract

The major goal of the present paper is to find out the manifestation of the boundedness of fluctuations. Two different subjects are considered: (i) an ergodic Markovian process associated with a new type of large scaled fluctuations at spatially homogeneous reaction systems; (ii) simulated dynamical systems that posses strange attractors. Their common property is that the fluctuations are bounded. It is found out that the mathematical description of the stochasity at both types of systems is identical. Then, it is to be expected that it exhibits certain common features whose onset is the stochasticity, namely: (i) The power spectrum of a time series of length $T$ comprises a strictly decreasing band that uniformly fits the shape $1/f^\alpha(f)$ where $\alpha(1/T)=1$ and $\alpha(f)$ strictly increases to the value $\alpha(\inf)=p$ ($p>2$) as $f$ approaches infinity. Practically, at low frequencies this shape is $1/f$-like with high accuracy because the deviations of the non-constant exponent $\alpha(f)$ from 1 are very small and become even smaller as the frequency tends to 1/T. The greatest advantage of the shape $1/\alpha(f)$ is that it ensures a finite variance of the fluctuations. (ii) It is found out that the structure of a physical and strange attractor is identical and they are non-homogeneous. (iii) The Kolmogorov entropy is finite., Comment: 18 pages, 2 figures

Abstract

OBJECTIVE Surgical skills laboratories augment educational training by deepening one’s understanding of anatomy and allowing the safe practice of technical skills. Novel, high-fidelity, cadaver-free simulators provide an opportunity to increase access to skills laboratory training. The neurosurgical field has historically evaluated skill by subjective assessment or outcome measures, as opposed to process measures with objective, quantitative indicators of technical skill and progression. The authors conducted a pilot training module with spaced repetition learning concepts to evaluate its feasibility and impact on proficiency. METHODS The 6-week module used a simulator of a pterional approach representing skull, dura mater, cranial nerves, and arteries (UpSurgeOn S.r.l.). Neurosurgery residents at an academic tertiary hospital completed a video-recorded baseline examination, performing supraorbital and pterional craniotomies, dural opening, suturing, and anatomical identification under a microscope. Participation in the full 6-week module was voluntary, which precluded randomizing by class year. The intervention group participated in four additional faculty-guided trainings. In the 6th week, all residents (intervention and control) repeated the initial examination with video recording. Videos were evaluated by three neurosurgical attendings who were not affiliated with the institution and who were blinded to participant grouping and year. Scores were assigned via Global Rating Scales (GRSs) and Task-based Specific Checklists (TSCs) previously built for craniotomy (cGRS, cTSC) and microsurgical exploration (mGRS, mTSC). RESULTS Fifteen residents participated (8 intervention, 7 control). The intervention group included a greater number of junior residents (postgraduate years 1–3; 7/8) compared to the control group (1/7). External evaluators had internal consistency within 0.5% (kappa probability > Z of 0.00001). The total average time improved by 5:42 minutes (p < 0.003; intervention, 6:05, p = 0.07; control, 5:15, p = 0.001). The intervention group began with lower scores in all categories and surpassed the comparison group in cGRS (10.93 to 13.6/16) and cTSC (4.0 to 7.4/10). Percent improvements for the intervention group were cGRS 25% (p = 0.02), cTSC 84% (p = 0.002), mGRS 18% (p = 0.003), and mTSC 52% (p = 0.037). For controls, improvements were cGRS 4% (p = 0.19), cTSC 0.0% (p > 0.99), mGRS 6% (p = 0.07), and mTSC 31% (p = 0.029). CONCLUSIONS Participants who underwent a 6-week simulation course showed significant objective improvement in technical indicators, particularly individuals who were early in their training. Small, nonrandomized grouping limits generalizability regarding degree of impact; however, introducing objective performance metrics during spaced repetition simulation would undoubtedly improve training. A larger multiinstitutional randomized controlled study will help elucidate the value of this educational method.

Abstract

Climate change affects timing of reproduction in many bird species, but few stud-ies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders in 201 populations of 104 bird species (N = 745,962 clutches) covering all continents between 1970 and 2019. Overall, average offspring production has declined in recent decades, but considerable differences were found among species and populations. A total of 56.7% of populations showed a declining trend in offspring production (significant in 17.4%), whereas 43.3% exhibited an increase (significant in 10.4%). The results show that climatic changes affect offspring production through compounded effects on ecological and life history traits of species. Migratory and larger-bodied species experienced reduced offspring production with increasing temperatures during the chick-rearing period, whereas smaller-bodied, sedentary species tended to produce more offspring. Likewise, multi-brooded species showed increased breeding success with increasing temperatures, whereas rising temperatures were unrelated to repro-ductive success in single-brooded species. Our study suggests that rapid declines in size of bird populations reported by many studies from different parts of the world are driven only to a small degree by changes in the production of young.

Abstract

Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders in 201 populations of 104 bird species (N = 745,962 clutches) covering all continents between 1970 and 2019. Overall, average offspring production has declined in recent decades, but considerable differences were found among species and populations. A total of 56.7% of populations showed a declining trend in offspring production (significant in 17.4%), whereas 43.3% exhibited an increase (significant in 10.4%). The results show that climatic changes affect offspring production through compounded effects on ecological and life history traits of species. Migratory and larger-bodied species experienced reduced offspring production with increasing temperatures during the chick-rearing period, whereas smaller-bodied, sedentary species tended to produce more offspring. Likewise, multi-brooded species showed increased breeding success with increasing temperatures, whereas rising temperatures were unrelated to reproductive success in single-brooded species. Our study suggests that rapid declines in size of bird populations reported by many studies from different parts of the world are driven only to a small degree by changes in the production of young., This meta-analysis was financed by the grant of the Polish National Science Centre (Narodowe Centrum Nauki) (no. 2017/27/B/NZ8/00465) awarded to Lucyna Hałupka.

Abstract

In the present paper a generalization of a theorem of I.B. Risteski (2004) concerning the solution of a nonlinear functional equation is given. The proof is based on a parametric approach by introducing a parameter in an arbitrary set , and on a matrix method for solving linear functional equations.

Abstract

BACKGROUND: Increasingly studies have identified socioeconomic factors adversely affecting healthcare outcomes for a multitude of diseases. To date, however, there has not been a study correlating socioeconomic details from nationwide databases on the prevalence of advanced coronary artery disease. We seek to identify whether socioeconomic factors contribute to advanced coronary artery disease prevalence in the United States. METHODS AND FINDINGS: State specific prevalence data was queried form the United States Nationwide Inpatient Sample for 2009. Patients undergoing percutaneous coronary angioplasty and coronary artery bypass graft were identified as principal procedures. Non-cardiac related procedures, lung lobectomy and hip replacement (partial and total) were identified and used as control groups. Information regarding prevalence was then merged with data from the Behavioral Risk Factor Surveillance System, the largest, on-going telephone health survey system tracking health conditions and risk behaviors in the United States. Pearson's correlation coefficient was calculated for individual socioeconomic variables including employment status, level of education, and household income. Household income and education level were inversely correlated with the prevalence of percutaneous coronary angioplasty (-0.717; -0.787) and coronary artery bypass graft surgery (-0.541; -0.618). This phenomenon was not seen in the non-cardiac procedure control groups. In multiple linear regression analysis, socioeconomic factors were significant predictors of coronary artery bypass graft and percutaneous transluminal coronary angioplasty (p

Abstract

Randomized trials have demonstrated the efficacy of craniectomy for the treatment of malignant cerebral edema following ischemic stroke. We sought to determine the prevalence and outcomes related to this by using a national database.Patient discharges with ischemic stroke as the primary diagnosis undergoing craniectomy were queried from the US Nationwide Inpatient Sample from 1999 to 2008. A subpopulation of patients was identified that underwent thrombolysis. Two primary end points were examined: in-hospital mortality and discharge to home/routine care. To facilitate interpretations, adjusted prevalence was calculated from the overall prevalence and two age-specific logistic regression models. The predictive margin was then generated using a multivariate logistic regression model to estimate the probability of in-hospital mortality after adjustment for admission type, admission source, length of stay, total hospital charges, chronic comorbidities, and medical complications.After excluding 71,996 patients with the diagnosis of intracranial hemorrhage and posterior intracranial circulation occlusion, we identified 4,248,955 adult hospitalizations with ischemic stroke as a primary diagnosis. The estimated rates of hospitalizations in craniectomy per 10,000 hospitalizations with ischemic stroke increased from 3.9 in 1999-2000 to 14.46 in 2007-2008 (p for linear trend

Abstract

Purpose The nonprofit Project Medishare launched a breast cancer treatment program in Port-au-Prince in July 2013 to address the demand for breast cancer care in Haiti. We outline the development of the program, highlight specific challenges, and discuss key considerations for others working in global oncology. Methods We reflected on our experiences in the key areas of developing partnerships, building laboratory capacity, conducting medical training, using treatment algorithms, and ensuring access to safe, low-cost chemotherapy drugs. We also critically reviewed our costs and quality measures. Results The program has treated a total of 139 patients with breast cancer with strong adherence to treatment regimens in 85% of patients. In 273 chemotherapy administrations, no serious exposure or adverse safety events were reported by staff. The mortality rate for 94 patients for whom we have complete data was 24% with a median survival time of 53 months. Our outcome data were likely influenced by stage at presentation, with more than half of patients presenting more than 12 months after first noticing a tumor. Future efforts will therefore focus on continuing to improve the level of care, while working with local partners to spread awareness, increase screening, and get more women into care earlier in the course of their disease. Conclusion Our experiences may inform others working to implement protocol-based cancer treatment programs in resource-poor settings and can provide valuable lessons learned for future global oncology efforts.

Abstract

A significant multi-state/regional unity of effort capability gap exists between the Department of Homeland Security (DHS) and the fifty states' independent emergency operations systems. Homeland Security Presidential Directives 5 and 8 directed the creation of the National Response Plan (NRP) and the supporting National Incident Management System (NIMS) which focus response to terrorist attack, natural disaster, or other major emergency. They mandated the creation, coordination, and rehearsal of plans at the national, state, and local levels and associated collective training events. Each level of government is required to maintain base capabilities to provide oversight of the creation, coordination, and review of their plans and to control execution during rehearsals or response to an actual event. The DHS is tasked with collecting and cross-leveling lessons learned and best practices. These steps meet the most basic threat scenarios and requirements, but they fall short by limiting immediate federal response to support of individual states. There is no standing capability to immediately synchronize federal and state support should a catastrophic event simultaneously influence multiple states. This paper studies the requirements for and utility of maintaining a regionally-based HLS/HLD collaboration and coordination capability.

Abstract

Despite its reduced use since the advent of magnetic resonance imaging, the high cervical myelogram remains a common diagnostic test in the evaluation of patients whose symptoms suggest cervical stenosis. We report a case of subarachnoid hematoma, hydrocephalus, and aseptic meningitis after a high cervical myelogram. A 52-year-old woman presented with headache, slurred speech, worsened neck pain and stiffness, and diffuse extremity weakness leading to gait instability beginning several hours after a cervical myelogram. Computed tomography (CT) scan revealed a C1-C2 hematoma below the dura, blood in the fourth and lateral ventricles, and hydrocephalus. An external ventricular drain was placed, and cerebrospinal fluid profile was consistent with aseptic meningitis. A suboccipital craniectomy and C1-C2 laminectomies were performed, followed by a C1-C2 durotomy, which revealed a large subarachnoid blood clot in the region of the cisterna magna extending down to the upper aspect of C2, which was evacuated by incising the arachnoid. In the midline at C1, an active source of intramedullary arterial bleeding on the dorsal surface of the spinal cord was coagulated. Spinal subarachnoid hematoma is a rare complication of high cervical myelogram. The extension of blood into the ventricular system with associated hydrocephalus has never been previously reported after myelography. Thus, severe persistent pain after cervical myelography should be evaluated by CT scans of the brain and cervical spine.

Abstract

Use of the Kerrison rongeur for bone removal in spinal surgery is associated with dural tears and cerebrospinal fluid (CSF) leaks. We report a modification of the Kerrison rongeur footplate designed to reduce the risk of dural tears. A novel footplate was designed by incorporating the following parameters: (1) tapering the footplate to deflect soft tissue downward during positioning of the rongeur underneath the bone, and (2) making the footplate longer and wider than the cutting element to prevent soft tissue from entering into the cutting surface. Stereolithography models of the modified footplate were made and tested in a cadaver. A stainless steel modified footplate was then incorporated into an existing Kerrison rongeur as a working prototype, and tested in 20 laminectomy cases to clinically validate its design. The modified footplate prevented soft tissue from entering the cutting surface of the Kerrison rongeur in the manner intended by its design. No dural tears or CSF leaks were encountered in any instance. Potential soft tissue compression caused by an increase in footplate dimensions was not a significant issue in the rongeur size tested. This modification, however, might not be practical in rongeurs larger than 3 mm. The risk of dural tears and cerebrospinal fluid leaks in spinal surgery may be reduced by this footplate modification of the Kerrison rongeur. Soft tissue compression may limit the incorporation of this modification to rongeurs of 3 mm or smaller. The promising results warrant further tests with a wider range of sizes., Center for Integration of Medicine and Innovative Technology (U.S. Army Medical Research Acquisition Activity Cooperative Agreement No. DAMD17-02-2-0006)
