Perfusion Services National Process Improvement Benchmarking
Authors: Riley J. B. , Kavanaugh T. A. 
Published: August 2023

The Joint Commission on Accreditation of Health Care Organizations recommends national and regional benchmarking in the quality improvement process. Benchmarking is comparing your organization's patient care process outcomes to the best. This communication describes a national benchmarking process for peer comparison of indicators in perfusion patient services process improvement.
A databasing communication aplet was designed to facilitate national benchmarking as part of a larger perfusion service management software application. When patient information is entered in the patient database post precedure, patient-specific numeric data and 'yes'/'no' queries are entered at the clinical site. At any time, the local perfusionist system manager may transmit their own data and receive national database group results by modem and a 1-800 phone number. Local indicator outcomes are compared to national results. Strategies are employed to assure that institution and patient name remain anonymous and institution specific data are stored at the clinical site. Participating institutions employ an e-mail aplet to discuss and decide which indicators to employ as a group.
Nine institutions have contributed outcome data for more than 6,425 cardiopulmonary bypass (CPB) procedures to a national database for ten months. National and institutional means for six discrete CPB outcome parameters are compared. The percent 'yes' responses to four procedure-related questions are compared. Joint Commission recommended benchmarking is accomplished while patient care is improved by comparing outcomes.
[18F]-PSMA-1007-PET for evaluation of kidney function
Authors: Rassek Philipp , Schäfers Michael , Rahbar Kambiz , Backhaus Philipp 
Published: August 2023

Abstract
Purpose Prostate-specific membrane antigen (PSMA) is present in the proximal tubule cells of the kidneys. This results in high renal tracer uptake in PSMA-PET, which may contain useful information on renal function. As part of the evaluation for [177Lu]-PSMA therapies, patients undergo PSMA-PET and additional [99mTc]-mercapto-acetyltriglycine (MAG3) scintigraphy to assess renal function. Aim of this study was to evaluate estimation of renal function with [18F]-PSMA-1007-PET/CT (PSMA-PET) by comparison to timely MAG3-scintigraphies.
Materials and Methods We retrospectively investigated 73 prostate cancer patients with 93 timely available PSMA-PET/CT, MAG3-scintigraphies and serum creatinine. For determination of split renal function in PSMA-PET/CT, we evaluated the relative unilateral total renal PSMA uptake, i.e. SUVmean multiplied by the renal volume (SRFPSMA-TOTAL) and relative unilateral maximal standardized uptake value (SRFSUV). These were compared to MAG3 split renal function (SRFMAG3) using Pearson correlation and receiver operating characteristics analysis. For determination of global renal function, correlation of bilateral total renal PSMA uptake with MAG3 tubular excretion rate and serum creatinine was assessed.
Results SRFMAG3 was strongly correlated with SRFPSMA-TOTAL (r= 0.872, p<0.001) and with SRFSUV (r=0.815, p<0.001). Relevant abnormalities of SRFMAG3 (unilateral renal function < 25 %) could be detected with sensitivities and specificities of 90% and 92% for SRFPSMA-TOTAL, and 80% and 95% for SRFSUV. Measures of absolute renal function were only weakly correlated with bilateral total renal PSMA uptake.
Conclusion Renal [18F]-PSMA-1007 uptake allowed to quantify renal split function with good accuracy based on SRFPSMA-TOTAL or SRFSUV.

Abstract
Background The COVID-19 pandemic has significantly affected acute ischemic stroke (AIS) care. In this study, we examined the effects of the pandemic on neurosurgical AIS care by means of decompressive surgery (DS).
Methods In this retrospective observational study, we compared the characteristics, in-hospital processes, and in-hospital mortality rates among patients hospitalized for AIS during the first four waves of the pandemic (between January 1, 2020 and October 26, 2021) versus the corresponding periods in 2019 (prepandemic). We used administrative data from a nationwide hospital network in Germany.
Results Of the 177 included AIS cases with DS, 60 were from 2019 and 117 from the first four pandemic waves. Compared with the prepandemic levels, there were no changes in weekly admissions for DS during the pandemic. The same was true for patient age (range: 51.7–60.4 years), the number of female patients (range: 33.3–57.1%), and the prevalence of comorbidity, as measured by the Elixhauser Comorbidity Index (range: 13.2–20.0 points). Also, no alterations were observed in transfer to the intensive care unit (range: 87.0–100%), duration of in-hospital stay (range: 14.6–22.7 days), and in-hospital mortality rates (range: 11.8–55.6%).
Conclusion In Germany, compared with the prepandemic levels, AIS patients undergoing DS during the first four waves of the pandemic showed no changes in demographics, rates of comorbidity, and in-hospital mortality rates. This is in contrast to previous evidence on patients with less critical types of AIS not requiring DS and underlines the uniqueness of the subgroup of AIS patients requiring DS. Our findings suggests that these patients, in contrast to AIS patients in general, were unable to forgo hospitalization during the COVID-19 pandemic. Maintaining the delivery of DS is an essential aspect of AIS care during a pandemic.
Propionibacterium acnes: A Difficult-to-Diagnose Ventriculoperitoneal Shunt Infection. Case Report
Authors: Kuzmin Dzmitry , Feigl Guenther C. 
Published: August 2023

Abstract
Background Ventriculoperitoneal (VP) shunt infections are a fairly common complication in both the early and late postoperative periods. Sometimes diagnosis is difficult despite the fact that infection is often accompanied by clinical symptoms. Furthermore, pathogenic bacteria can be detected in the cerebrospinal fluid.
Method We describe a case of chronic VP shunt infection in a 24-year-old female patient who was operated on for posterior fossa pilocytic astrocytoma and needed a VP shunt. The infection revealed itself 5 years after shunt implantation with nonspecific symptoms, and it took approximately 2 years to make a correct diagnosis. Meanwhile, the patient's condition became critical. The infection was caused by Propionibacterium acnes, which is capable of forming biofilms on implants, and which is difficult to identify due to the peculiarity of its cultivation.
Result When the bacterium was identified, the shunt was replaced and antimicrobial therapy was performed, after which the patient's condition improved dramatically and she got back to her normal life.
Conclusions This case shows how difficult the diagnosis of VP shunt infection can be and what clinical significance it can have for the patient.

Published: August 2023

AbstractIn this integrative review, we aimed to describe the records of time devoted by physicians to breast ultrasound in a review of articles in the literature, in order to observe whether the automation of the method enabled a reduction in these values. We selected articles from the Latin American and Caribbean Literature in Health Sciences (LILACS) and MEDLINE databases, through Virtual Health Library (BVS), SciELO (Scientific Electronic Library Online), PubMed, and Scopus. We obtained 561 articles, and, after excluding duplicates and screening procedures, 9 were selected, whose main information related to the guiding question of the research was synthesized and analyzed. It was concluded that the automation of breast ultrasound represents a possible strategy for optimization of the medical time dedicated to the method, but this needs to be better evaluated in comparative studies between both methods (traditional and automated), with methodology directed to the specific investigation of this potentiality.
Increased Cesarean Section Rates during the COVID-19 Pandemic: Looking for Reasons through the Robson Ten Group Classification System
Authors: Silva Cassia Elane Berbel da , Guida Jose Paulo Siqueira , Costa Maria Laura 
Published: August 2023

Abstract
Objective To compare cesarean section (CS) rates according to the Robson Ten Group Classification System (RTGCS) and its indications in pregnant women admitted for childbirth during the first wave of the coronavirus disease 2019 (COVID-19) pandemic with those of the previous year.
Materials and Methods We conducted a cross-sectional study to compare women admitted for childbirth from April to October 2019 (before the pandemic) and from March to September 2020 (during the pandemic). The CSs and their indications were classified on admission according to the RTGCS, and we also collected data on the route of delivery (vaginal or CS). Both periods were compared using the Chi-squared (χ2) test or the Fisher exact test.
Results In total, 2,493 women were included, 1,291 in the prepandemic and 1,202 in the pandemic period. There was a a significant increase in the CS rate (from 39.66% to 44.01%; p = 0.028), mostly due to maternal request (from 9.58% to 25.38%; p < 0.01). Overall, groups 5 and 2 contributed the most to the CS rates. The rates decreased among group 1 and increased among group 2 during the pandemic, with no changes in group 10.
Conclusion There was an apparent change in the RTGSC comparing both periods, with a significant increase in CS rates, mainly by maternal request, most likely because of changes during the pandemic and uncertainties and fear concerning COVID-19.

Published: August 2023

AbstractThe aim of the present study was to identify how the transition of care from the hospital to the community occurs from the perspective of puerperal women at risk. An integrative literature review was performed, with the question: “How does the transition of care for at-risk puerperal women from the hospital to the community occur?” The search period ranged from 2013 to 2020, in the following databases: PubMed, LILACS, SciELO, and Scopus. MESH, DeCS and Boolean operators “OR” and “AND” are used in the following crossover analysis: patient transfer OR transition care OR continuity of patient care OR patient discharge AND postpartum period, resulting in 6 articles. The findings denote discontinuity of care, given the frequency of non-adherence to the puerperal consultation. Transition studies of care in the puerperium were not found, which requires proposing new studies.
An ultra-high timing resolution pulse generator with spur suppression and correction of errors based on real-time computation
Authors: Liu Hanglin , Fu Zaiming , Kong Dexuan 
Published: August 2023

In this paper, a novel ultra-high timing resolution pulse generator is proposed. It is based on the waveform real-time computation method. Through real-time computing and filtering of the waveform samples, a pulse with a 0.1 ps timing resolution pulse could be generated at a 2.5 GSPS sampling rate. Based on the waveform real-time computation method, jitters are injected into the waveform time parameter to break the harmonic components caused by non-integer multiples of the sampling rate and waveform frequency. Waveform spurs are further suppressed using this approach. The pulse error correction is achieved by designing digital filters that complement the waveform distortion features. The complementary digital filters are then combined as Farrow filter coefficients by polynomial fitting. Based on the real-time computation method, pulse width modulation, frequency modulation, and amplitude modulation are easy to realize. The implemented pulse generator has four channels, whose minimum pulse width, edge time, frequency range, and amplitude range are 4, 2.5 ns, 1 μHz–120 MHz, and 50 mVpp–5 Vpp, respectively. All timing resolution and timing accuracy of pulse width, edge time, pulse period, and channel delay are 0.1 and 50 ps, respectively. Timing parameters can be changed continuously without glitches.
A view of American farm policy in transition
Authors: Coppess Jonathan 
Published: August 2023

Abstract
Reauthorization of the Farm Bill is scheduled for 2023 and the agenda of the 118th Congress (2023–2024) elected in the 2022 midterms. The Farm Bill is the main legislative vehicle for American farm and food policy. The Farm Bill was last reauthorized by the Agricultural Improvement Act of 2018, but the years since that time have featured four programs that made direct payments to farmers but were not authorized by Congress in the Farm Bill, commonly referred to as ad hoc assistance. In addition, the 117th Congress (2021–2022) enacted the Inflation Reduction Act which invested an additional US$18 billion into farm conservation programs over multiple years. This article reviews the ad hoc assistance and Inflation Reduction Act with comparisons to previous instances of ad hoc assistance, applying some lessons from history and seeking to gauge the extent to which the non-farm bill efforts provide leading indicators or signals about changes to, or a transition in, American farm policy.

Abstract
In order to further investigate the conditions and the coupling mechanisms for generating the hollow cathode effect (HCE) for the process optimization in the field of surface modification, the plasma distribution and density in single glow and double glow hollow cathode discharge (HCD) were explored by experiments and simulations based on the two-dimensional fluid model. Additionally, we investigated the effects of the key parameters on the plasma density, the electron temperature and the potential field during the HCD. The experimental and simulation results showed that the high plasma density is owing to the HCE in the hollow cathode. It is found that there is a critical pore diameter for generating HCE, which is approximately the sum of the thickness of the plasma sheath and four times the electron-neutral mean free path in the single glow discharge while twice thickness of the plasma sheath and four times the electron-neutral mean free path in the double glow discharge. The HCE in the double glow discharge can be observed when the ignition voltage that the source cathode voltage be 250 V greater than the workpiece cathode voltage can be met while the PD value is about 1.5 ∼ 3.8 Torr

mm. Consequently, we believe that our investigation on the plasma characteristics of hollow cathode in glow discharge will contribute to the development of the more optimal processing parameters for the application of the glow plasma discharge phenomena.
Astronomical measurements 1923–2023: a century of astonishing progress
Authors: Edmunds M G 
Published: August 2023

Abstract
How have advances in technology changed astronomy over the past 100 years? In this very brief review I will give examples of just how closely discovery has followed technical innovation, allowing observations that would previously have seemed impossible. Obviously great progress has come from spaceflight allowing observations from outside the Earth’s atmosphere. But two other factors have also been crucial—the development of efficient detectors of electromagnetic radiation and the application of computers to both instrument control and data analysis. Driving down experimental errors in pursuit of ever-more accurate measurements has been important too. I will particularly highlight advances in cosmology, the nature of galactic nuclei and the discovery of exoplanets.

Published: August 2023

Abstract
As an important part of soft robots, artificial muscles have received increasing attention. And since artificial muscles are developed by imitating the characteristics of biological muscles, they are naturally suitable for bionic applications. Shape memory alloys (SMAs) have been widely used in the field of artificial muscles due to their high energy density, biocompatibility, corrosion resistance, and self-sensing properties. In this review, the bionic applications of SMA artificial muscles are classified and summarized, and they are divided into two categories: bionic robotics (animal imitation) and biomedical (human imitation) applications. In the part of bionic robots, we summarize the applications of SMA artificial muscles in bionic robots such as flying, jumping, walking, crawling and swimming robots according to the motion characteristics. In the part of biomedical applications, we summarize the applications of SMA artificial muscles in various parts of the human body. In addition, this review also counts the proportion of SMA wires and springs used in applications, and provides a reference for the subsequent selection of SMA wires and springs. Finally, the challenges and opportunities of SMA artificial muscles are summarized and prospected.
Weierstrass elliptic function solutions and degenerate solutions of a variable coefficient higher-order Schrödinger equation
Authors: Fan Lulu , Bao Taogetusang 
Published: August 2023

Abstract
In this paper, the auxiliary equation method is used to study the Weierstrass elliptic function solutions and degenerate solutions of the variable coefficient higher order Schrödinger equation, including Jacobian elliptic function solutions, trigonometric function solutions and hyperbolic function solutions. The types of solutions of the variable coefficient higher-order Schrödinger equation are enriched, and the method of seeking precise and accurate solutions is extended. It is concluded that the types of degenerate solutions are related to the coefficients of the equation itself when the degenerate solutions are obtained from the solutions of the Weierstrass elliptic functions. In addition, the solutions form of the equation is extended from the power series expansion form to the Laurent series expansion form, and the corresponding solutions are obtained. After the conversion formula between the Weierstrass elliptic function solutions and the Jacobian elliptic function solutions is constructed, the Jacobian elliptic function solutions of the higher order Schrödinger equation with variable coefficients are also obtained. These have not been previously studied.
Effect of Co doping of (Ga, In) and 2N preferred orientation on the magnetic and optical properties of ZnO
Authors: Hou Qingyu , Qi Mude , Si Riguleng 
Published: August 2023

Abstract
Current research on the Zn1−xMxO1−yNy (M = Ga, In) system mainly focuses on the p-type property, where Ga–N or In–N has different preferred orientations for bonding. Studies on the magnetic, bandgap, and optical properties of ZnO co doped with N are also lacking. The generalized gradient approximation (GGA+U) plane wave ultrasoft pseudopotential method based on density functional theory is used to systematically investigate the effects of the magnetic, band gap, and optical properties of the system for addressing the aforementioned problems. Results show that the formation energy of the Zn1−xMxO1−yNy (M = Ga, In) system is negative, all doping is easy, and all doped systems are stable and magnetic. The magnetism comes from the double exchange effect of electron spin polarization. Research has found that the band gap in Ga–N or In–N bonding along the c-axis direction is narrower than that along the a-axis direction. In the low-energy region, the redshift of the absorption spectrum is more significant, and the absorption or reflection coefficient and the carrier polarization and activity are stronger. In particular, In–N forms bonds along the c-axis direction and is co doped with another N in ZnO, which results in the narrowest band gap and the most significant redshift in the absorption spectrum. The absorption of sunlight can also be achieved in the ultraviolet visible near-infrared region. The absorption or reflection coefficient and the carrier polarization and activity are relatively strongest. This work has certain reference value for the design and preparation of new solar cell light absorbing materials based on ZnO.
