Authors: Jaouad Yousfi  , Soukaina Oumlil  , Laila Benjilali  , Lamiaa Essaadouni
Published: May 2021

Necrotizing fasciitis is a serious soft tissue infection that causes necrosis of the subcutaneous tissues and the muscle fascia. It is associated with a high mortality rate of around 25%. Necrotizing fasciitis of the breast is a rare entity. It is a rapidly progressive life-threatening condition which can lead to sepsis with multiple organ failure. We describe a case of necrotizing fasciitis of the right breast in a 48-year-old patient diagnosed with systemic sclerosis–rheumatoid arthritis overlap syndrome.

Monocular Diplopia in Idiopathic Intracranial Hypertension: A Case Report and Literature Review
Authors: Palmieri Gianluigi R , Sansone Mattia , De Simone Roberto , Moccia Marcello
Published: May 2021

Background: Diplopia is the double vision of a single object, and can be binocular or monocular. Binocular diplopia is caused by the misalignment of the visual axes, with images falling on the fovea of the fixating eye and on the extra-foveal retina of the non-fixating eye, as a consequence of both neurological (i.e., oculomotor nerve palsies, ocular myopathies, neuromuscular junction disorders) and ophthalmic disorders (i.e., decompensation of a pre-existing strabismus). In contrast, monocular diplopia is generally explained by intraocular pathology (i.e., refractive errors, ocular media abnormalities, dry eyes), causing the image of a single object to fall, at the same time, on the fovea and on the extra-foveal retina of the same eye. Methods: We report the case of a 22-year-old woman presenting with acute-onset monocular diplopia. Results: The diagnosis of idiopathic intracranial hypertension (IIH) was based on the presence of papilloedema and elevated cerebrospinal fluid (CSF) pressure. Monocular diplopia resolved after CSF subtraction. Conclusions: We describe a case of monocular diplopia as a presenting symptom of IIH, and discuss diagnostic issues of this possibly underestimated symptom in neurology clinical practice. Careful ophthalmic and neuro-ophthalmic examination can identify clinical features of diplopia, and drive diagnosis and treatment.

Authors: Jaouad Yousfi  , Fatimazahra Bensalek  , Mouna Zahlane  , Laila Benjilali  , Lamiaa Essaadouni
Published: May 2021

Introduction: Myasthenia gravis is a rare autoimmune disease caused by autoantibodies directed against the synapses of the neuromuscular junction. Patient and methods: We report the case of a young patient with myasthenia gravis associated with Hodgkin's lymphoma. Results: A 22-year-old patient presented with a 2-month history of severe weakness associated with muscle fatigability and intermittent ptosis without dysphonia or respiratory signs. Clinical examination revealed generalized myasthenia. The EMG did not show post-synaptic block, and anti-acetylcholine receptor antibodies were elevated at 3 nmol/l (normal ?0.3 nmol/l). CT of the thorax showed an anterior medial mass. Immunohistochemistry of the mass revealed mixed cellularity Hodgkin’s lymphoma. Conclusion: The association of lymphomas with myasthenia gravis has been rarely reported.
Determinants of Credit in Indonesia's Agricultural Sub-Sector: Panel Data Analysis
Authors: Yuniarti Dini , Yuniarto Arif Sapto
Published: May 2021

Credit has a role in agricultural development and the income of small farmers which will reduce poverty levels. However, the portion of credit in the agricultural sector is still relatively small. This study aims to examine  determinants of credit in the agricultural sub-sector. The factors include credit rating, credit interest rates, Gross Domestic Product and the number of farmers in the agricultural sub-sector. The data used are secondary data, a combination of cross-sectional data including the agricultural sub-sector, namely food crops, horticultural crops, plantations and livestock and seres times including 2011-2019. The analysis tool used is the regression data panel. The study results show that the number of creditors in the agricultural sector is positive and significant by the number of farmers and Gross Domestic Product, while interest does not affect the credit rating of the agricultural sub-sector. Policies that can be taken are to increase the Gross Domestic Product of the agricultural sector to increase the capacity of farmers. In addition, to increase farmers' access to financial institutions, financial education is needed, so that it will increase financial literacy.

Application of Supplemental Irrigation Based on Testing Soil Moisture in Winter Wheat
Authors: Han Zhan-Jiang
Published: May 2021

Water shortage is a serious problem threatening sustainable development of agriculture in the North China Plain, where winter wheat is the largest water-consuming crop. The objective of this study was to optimize irrigation scheme for high yield and high water use efficiency (WUE) in wheat (Triticum aestivum L.), on the basis of Jimai 22, a represented cultivar in production. In the field experiments conducted in growing seasons, unfixed amount of water was supplied at sowing, jointing, and anthesis stages to adjust the soil moisture into a controlled ladder. For example, the relative soil moisture contents in the W0 treatment were 85% at sowing, 80% at jointing, and 70% at anthesis; in the W1 treatment, they were 85%, 85%, and 70%, respectively; analogically, they were 85%, 85%, and 75% in the W2 treatment and 85%, 90%, and 80% in the W3 treatment. The results showed that WUE was higher in W0 than in other treatments. However, the grain yield was the lowest in treatment W0. In growing seasons, the grain yield, irrigation water use efficiency (WUEI), precipitation use efficiency (WUEP), and irrigation benefit (IB) in W1, W2, and W3 were decreased significantly because more water was supplied. Under the experimental condition, the W1 regime was considered as the optimum. In this regime, the relative soil moisture contents at 0–140 cm soil layer were controlled to 85% at sowing, 80% at jointing, and 70% at anthesis stages. When 15.32 mm of water was supplied in growing seasons, the final grain yields of W1 treatment were 8185.75 kg ha-1, and the WUEI and WUEP were the highest among the 4 treatments. The deep soil water content (0-140 cm) can be estimated by shallow soil moisture content (0-60 cm), which is more conducive to estimate the deep soil water content through shallow soil and reduce the workload of supplemental irrigation based on testing soil moisture.
High-sensitivity and large-range fiber optic temperature sensor based on PDMS-coated Mach-Zehnder interferometer combined with FBG

Published: May 2021

Although numerous efforts have been dedicated towards developing fiber sensors with high performances, challenges still remain in achieving high-quality temperature sensors with high sensitivity, large measurement range and high stability. This study proposes a compact fiber optic temperature sensor based on PDMS-coated Mach-Zehnder interferometer (MZI) combined with FBG, and it can realize both high-sensitivity and large-range temperature measurement. The MZI is based on Thin No-Core Fiber (TNCF) with lateral-offset. Owing to the high refractive index sensitivity of MZI and the high thermo-optic coefficient of PDMS, the sensor can achieve a high temperature sensitivity (>10 nm/°C). Besides, by optimizing the TNCF length, the cascaded FBG can be used to locate different temperature intervals in units of approximately 10 °C, and therefore the detectable temperature range is largely extended. The experimental test demonstrates that the average sensitivities of 11.19 nm/°C, 8.53 nm/°C, 7.76 nm/°C, 7.27 nm/°C are achieved at the temperature around 30 °C, 40 °C, 50 °C and 60 °C, and it shows excellent consistency and repeatability during the thermal cycle tests.

Authors: Zhang Nan , Ding Shihao , Wang Kai , Lyu Quan , Sun Wei Xiao
Published: May 2021

Transparent quantum-dot light-emitting diodes (Tr-QLEDs) with an inverted architecture has been developed. The inverted Tr-QLEDs are designed for integrating with thin-film transistors (TFTs) circuit easily. The 1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile (HAT-CN) is employed as a hole injection layer (HIL) as well as a buffer layer in the inverted Tr-QLEDs. An optimized HAT-CN as dual-functional modified layer facilitates charge injection balance and meanwhile reduces the plasma damage caused by sputtering process. High performance device with a peak current efficiency (CE) and maximum external quantum efficiency (EQE) of 14.7 cd/A and 11.3% was obtained, wherein the EQE is the highest record for Tr-QLEDs. The transmittance of the Tr-QLEDs at 550 nm reached up to 78%. These Tr-QLEDs possess potential for the next-generation transparent displays applications.
Water resource management: IWRM strategies for improved water management. A systematic review of case studies of East, West and Southern Africa
Authors: Dirwai Tinashe Lindel , Kanda Edwin Kimutai , Senzanje Aidan , Busari Toyin Isiaka
Published: May 2021

Objective

The analytical study systematically reviewed the evidence about the IWRM strategy model. The study analysed the IWRM strategy, policy advances and practical implications it had, since inception on effective water management in East, West and Southern Africa.

Methods

The study adopted the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) and the scoping literature review approach. The study searched selected databases for peer-reviewed articles, books, and grey literature. DistillerSR software was used for article screening. A constructionist thematic analysis was employed to extract recurring themes amongst the regions.

Results

The systematic literature review detailed the adoption, policy revisions and emerging policy trends and issues (or considerations) on IWRM in East, West and Southern Africa. Thematic analysis derived four cross-cutting themes that contributed to IWRM strategy implementation and adoption. The identified four themes were donor effect, water scarcity, transboundary water resources, and policy approach. The output further posited questions on the prospects, including whether IWRM has been a success or failure within the African water resource management fraternity.
Racial and ethnic disparities in benefits eligibility and spending among adults on the autism spectrum: A cohort study using the Medicare Medicaid Linked Enrollees Analytic Data Source
Authors: Benevides Teal W. , Carretta Henry J. , Rust George , Shea Lindsay
Published: May 2021

Background

Research on children and youth on the autism spectrum reveal racial and ethnic disparities in access to healthcare and utilization, but there is less research to understand how disparities persist as autistic adults age. We need to understand racial-ethnic inequities in obtaining eligibility for Medicare and/or Medicaid coverage, as well as inequities in spending for autistic enrollees under these public programs.

Methods

We conducted a cross-sectional cohort study of U.S. publicly-insured adults on the autism spectrum using 2012 Medicare-Medicaid Linked Enrollee Analytic Data Source (n = 172,071). We evaluated differences in race-ethnicity by eligibility (Medicare-only, Medicaid-only, Dual-Eligible) and spending.

Findings

The majority of white adults (49.87%) were full-dual eligible for both Medicare and Medicaid. In contrast, only 37.53% of Black, 34.65% Asian/Pacific Islander, and 35.94% of Hispanic beneficiaries were full-dual eligible for Medicare and Medicare, with most only eligible for state-funded Medicaid. Adjusted logistic models controlling for gender, intellectual disability status, costly chronic condition, rural status, county median income, and geographic region of residence revealed that Black beneficiaries were significantly less likely than white beneficiaries to be dual-eligible across all ages. Across these three beneficiary types, total spending exceeded $10 billion. Annual total expenditures median expenditures for full-dual and Medicaid-only eligible beneficiaries were higher among white beneficiaries as compared with Black beneficiaries.

Conclusions

Public health insurance in the U.S. including Medicare and Medicaid aim to reduce inequities in access to healthcare that might exist due to disability, income, or old age. In contrast to these ideals, our study reveals that racial-ethnic minority autistic adults who were eligible for public insurance across all U.S. states in 2012 experience disparities in eligibility for specific programs and spending. We call for further evaluation of system supports that promote clear pathways to disability and public health insurance among those with lifelong developmental disabilities.

Published: May 2021

Glaucoma is a leading cause of blindness worldwide whose detection is based on multiple factors, including measuring the cup to disc ratio, retinal nerve fiber layer and visual field defects. Advances in image processing and machine learning have allowed the development of automated approached for segmenting objects from fundus images. However, to build a robust system, a reliable ground truth dataset is required for proper training and validation of the model. In this study, we investigate the level of agreement in properly detecting the retinal disc in fundus images using an online portal built for such purposes. Two Doctors of Optometry independently traced the discs for 159 fundus images obtained from publicly available datasets using a purpose-built online portal. Additionally, we studied the effectiveness of ellipse fitting in handling misalignments in tracing. We measured tracing precision, interobserver variability, and average boundary distance between the results provided by ophthalmologists, and optometrist tracing. We also studied whether ellipse fitting has a positive or negative impact on properly detecting disc boundaries. The overall agreement between the optometrists in terms of locating the disc region in these images was 0.87. However, we found that there was a fair agreement on the disc border with kappa = 0.21. Disagreements were mainly in fundus images obtained from glaucomatous patients. The resulting dataset was deemed to be an acceptable ground truth dataset for training a validation of models for automatic detection of objects in fundus images.
Unskilled beauty or ugly truth? A dialogic study of the indexical line
Authors: Neves Joana P. R.
Published: May 2021

A skilled drawing elicits an elevated aesthetic pleasure that we tend to call beauty. However, conceptual approaches to art influenced by science in association with technology subverted the discipline of drawing and notions of skill and beauty by focusing on the phenomenal world, including the human mind, in a more abstract and schematic way through an indexical line. The displacement of skill and beauty through the notion of a ‘truthful’ and perhaps even ethical line may pluralize beauty (the eternal regulator) and disable – literally – traditional notions of what the body can or should do. This study follows dialogically a number of indexical lines, from the art historian Pliny the Elder twenty-one centuries ago, to the deaf contemporary artist Christine Sun Kim (b. 1980) whose work explores the notations of sound through drawing, including Etienne-Jules Marey’s (1830–1904) graphic recording machines and Irma Blank’s (b. 1934) conceptual drawn writings.

‘Fake news’ or trust in authorities? The problems of uncertainty at a time of medical crisis
Authors: Glenn Ian
Published: May 2021

This article examines the complex boundaries between ‘fake news’, speculation, hypothesis, gossip and whistleblowing during the COVID-19 pandemic. It shows that apparently authoritative sources and experts gave information or policy recommendations that have turned out to be wrong, sometimes dangerously so, and explores the kinds of bias that enter medical advice and planning decisions. The article then diagnoses a WhatsApp voice-note from a young South African doctor that went viral and was denounced as ‘fake news’ because of obvious errors. This note, however, revealed behind the scenes medical thinking about subjects that professional bodies and authorities usually avoid discussing publicly. In highlighting what apparently authoritative sources omit and distort, the article suggests that journalists should report medical advice, even from authoritative sources, with caution and shows that apparently ‘fake’ news may reveal issues other news sources neglect.

Postsekularyzm w badaniach geograficznych
Authors: Bilska-Wodecka Elżbieta
Published: May 2021

Celem artykułu jest prezentacja stanu badań geograficznych prowadzonych w nurcie postsekularyzmu. Geografia zaliczana jest do grupy tych dyscyplin naukowych, które jako jedne z pierwszych włączyły się w postsekularny dyskurs, nawiązując w warstwie teoretycznej do myśli Jürgena Habermasa. Geografowie w swoich badaniach podkreślają, że pomimo obserwowanego stopniowego powrotu religii do przestrzeni publicznej sekularyzacja i desekularyzacja mogą występować jednocześnie. Geografia wzbogaca myśl postsekularną o analizę interakcji sekularyzmu i sakralności w przestrzeni. Ważnym tematem badań jest wpływ symboliki lub kodu kulturowego na wyrażenie religijnej tożsamości osób i miejsc, ze szczególnym uwzględnieniem przestrzeni miejskiej. W badaniach geograficznych zwraca się też uwagę m.in. na kapitał duchowy człowieka (VBA) oraz działalność organizacji opartych na wierze (FBOs), których wolontariusze – o różnych tożsamościach religijnych – pracują na rzecz wykluczonych grup społecznych.
Asymptotic solution of the Cauchy problem for the singularly perturbed partial integro-differential equation with rapidly oscillating coefficients and with rapidly oscillating heterogeneity
Authors: Kalimbetov Burkhan T. , Tuychiev Olim D.
Published: May 2021

In this paper, the regularization method of S. A. Lomov is generalized to integro-differential equations with rapidly oscillating coefficients and with a rapidly oscillating right-hand side. The main goal of the work is to reveal the influence of the oscillating components on the structure of the asymptotics of the solution of this problem. The case of coincidence of the frequencies of a rapidly oscillating coefficient and a rapidly oscillating inhomogeneity is considered. In this case, only the identical resonance is observed in the problem. Other cases of the relationship between frequencies can lead to so-called non-identical resonances, the study of which is nontrivial and requires the development of a new approach. It is supposed to study these cases in our further work.

Published: May 2021

Comorbid social anxiety and alcohol use disorders (SAD-AUD) in the community and the complex interactions that occur between these disorders have emerged as a significant clinical, public health, and research issue. The authors examined (a) the rates of comorbid SAD-AUD, (b) the impact of comorbid SAD-AUD on outcomes targeting social anxiety disorder, and (c) the effect of pretreatment alcohol consumption and alcohol use before, during, and after social situations on a composite measure of social anxiety in 172 adults presenting with social anxiety disorder. There was low incidence of AUD in this sample of individuals with SAD. Results indicated that alcohol consumption did not lead to worse social anxiety symptoms; however, alcohol use before and during social situations was associated with more severe social anxiety symptoms. These findings suggest that the function of alcohol use may be more important than the overall level of alcohol use and has implications for treatment.
Working with people experiencing psychotic disorders and co-occurring nicotine dependence: Attitudes and reflections from psychologists on the Healthy Lifestyles research trial
Authors: Kay-Lambkin Frances , Searl Amanda , Johnson Martin P. , Baker Amanda
Published: May 2021

The combination of psychotic and substance use disorders compounds the well-documented challenges of treatment engagement, retention, and outcome for these single conditions. This study focuses on the formation of alliance among this important clinical group. Psychologists working on a research trial participated in qualitative interviews focused on their impression of delivering treatment to people with psychotic disorders and concurrent nicotine dependence. Utilizing Interpretive Phenomenological Analysis, the authors highlighted the complex and unusual experience of working with people with psychotic disorders and concurrent nicotine dependence, the importance of considering each client as an individual, and the many layers of interaction between therapist and client. The authors found that meaningful therapeutic relationships over the longer term are possible, even when active symptoms are present. There is also potential for telephone-based treatments to work well. Clinical supervision and support, tailored to the unique experience of therapists working with psychotic populations, is pivotal.

Cânone Romântico Brasileiro: exclusão das lutas indígenas e suas implicações para o presente
Authors: Honorato Suene
Published: May 2021

Gonçalves Dias e José de Alencar, os dois autores mais conhecidos do romantismo brasileiro, construíram obras literárias em que o indígena figura como vítima de um passado histórico. Já nas obras de autores como Lourenço Amazonas, Couto de Magalhães e Gonçalves de Magalhães, hoje pouco lembradas, pode-se encontrar um indígena que atua como agente histórico, em disputa com o colonizador. A análise da representação indígena nas obras desse conjunto de autores, tendo em vista a distinção entre política indigenista e política indígena (CUNHA, 2012), me permitirá discutir em que medida a produção do reconhecimento (política literária) tem implicações nos modos de se pensar a questão indígena no presente.
Plastic Pollution
Authors: Baierl Tessa-Marie , Bogner Franz X.
Published: May 2021

Plastic pollution is ubiquitous and there is growing concern about its consequences. Given that current research findings often reach the public insufficiently, the issue should be addressed at school. To create a fruitful learning experience, we propose three associated hands-on, inquiry-based learning activities that require little equipment. Students learn about the origins and properties of plastics, investigate everyday sources, learn about recycling, address and reflect upon the material’s (dis)advantages, and are encouraged to consider solutions. All activities align with the Next Generation Science Standards and are primarily designed for the middle school classroom; we further provide modifications for elementary and high school settings.

Published: May 2021

Soil provides innumerable valuable ecosystem services, such as the production of food and the direct support of wildlife, by ensuring the availability of adequate habitat. However, unsustainable human activities are resulting in degradation of soils worldwide. Hence, it is of utmost importance to raise awareness about this often-overlooked environmental issue. This article presents an inquiry-based activity that challenges students to assess the ecological quality of soil in the surroundings of their classroom. Plus, students and teachers are invited to become citizen scientists by sharing their data with researchers, thus contributing to a future endeavor to map soil quality through broad geographic ranges.
Using Pulse Oximetry to Illustrate Homeostasis in the Secondary Biology Laboratory
Authors: Entress Cole , Morehouse Christian
Published: May 2021

To survive, complex organisms must maintain homeostasis by coordinating the activity of interacting, hierarchical systems. This is a core biological idea in the Next Generation Science Standards and one that many students find challenging. The most common lab exercise used to introduce homeostasis – a mini-experiment in which students measure how physical activity affects their pulse and respiratory rate – fails to show any direct evidence of internal stability. In this article, we describe how modifying this lab using an inexpensive pulse oximeter rectifies this shortcoming, giving students the ability to collect laboratory data that show both change and dynamic stability.
A Call for Greater Modesty in Psychology and Cognitive Neuroscience
Authors: Ramsey Richard
Published: May 2021

Exaggerated claims and low levels of reproducibility are commonplace in psychology and cognitive neuroscience, due to an incentive structure that demands “newsworthy” results. My overall argument here is that in addition to methodological reform, greater modesty is required across all levels - from individual researchers to the systems that govern science (e.g., editors, reviewers, grant panels, hiring committees) - to redirect expectations regarding what psychological and brain science can effectively deliver. Empirical work and the reform agenda should pivot away from making big claims on narrow evidence bases or single tools and focus on the limitations of our individual efforts, as well as how we can work together to build ways of thinking that enable integration and synthesis across multiple modalities and levels of description. I outline why modesty matters for science including the reform agenda, provide some practical steps that we can take to embrace modesty, rebut common misconceptions of what modesty means for science, and present some limitations of the approach. Ultimately, by presenting a more sober view of our capacities and achievements, whilst placing work within a wider context that respects the complexity of the human brain, we will bolster the fidelity of scientific inference and thus help in a small way to generate a firmer footing upon which to build a cumulative science.
Ballet Fit for a National Theater? Carré, the Critics, and Le Cygne at the Opéra-Comique
Authors: Gutsche-Miller Sarah
Published: May 2021

When Albert Carré became the director of the Paris Opéra-Comique in 1898, he did so with the goal of rejuvenating French lyric theater. He also took possession of a national institution in a state of flux. The Opéra-Comique had a new hall and a new mandate, and it had recently become the focus of debates in the press about what role the city’s second national lyric theater should play in French culture. Although debates initially revolved around opera, Carré’s plans for renewal included ballet, not seen at the Opéra-Comique for over a century.

This article discusses the role ballet played in promoting Carré’s artistic objectives. At first glance the theater’s repertoire appears to be at odds with Carré’s progressive ideals. The Opéra-Comique staged only one innovative ballet, Le Cygne (1899)—a pop-culture-inflected mythological parody by Catulle Mendès, Charles Lecocq, and Madame Mariquita. Carré then turned to staging old-fashioned pantomime-ballets, confining innovative dances to divertissements in operas.

The reasons for Carré’s repertoire decisions can, I argue, be found in the reception of Le Cygne. Carré’s initial ballet was highly contested, and critics’ arguments mirrored ongoing press debates about ballet’s value and place in French culture. I contend that Carré’s initial modernist ballet, and his shift to mixing conventional pantomime-ballets with modern opera divertissements in response to the contentious reception of Le Cygne, were part of a calculated attempt to establish the Opéra-Comique as an emblematic French national theater that was simultaneously a museum and a progressive space for modern innovation.

Potassium‐coupled chloride transporters (KCCs) play crucial roles in regulating cell volume and intracellular chloride concentration. They are characteristically inhibited under isotonic conditions via phospho‐regulatory sites located within the cytoplasmic termini. Decreased inhibitory phosphorylation in response to hypotonic cell swelling stimulates transport activity, and dysfunction of this regulatory process has been associated with various human diseases. Here, we present cryo‐EM structures of human KCC3b and KCC1, revealing structural determinants for phospho‐regulation in both N‐ and C‐termini. We show that phospho‐mimetic KCC3b is arrested in an inward‐facing state in which intracellular ion access is blocked by extensive contacts with the N‐terminus. In another mutant with increased isotonic transport activity, KCC1Δ19, this interdomain interaction is absent, likely due to a unique phospho‐regulatory site in the KCC1 N‐terminus. Furthermore, we map additional phosphorylation sites as well as a previously unknown ATP/ADP‐binding pocket in the large C‐terminal domain and show enhanced thermal stabilization of other CCCs by adenine nucleotides. These findings provide fundamentally new insights into the complex regulation of KCCs and may unlock innovative strategies for drug development.

Authors: Fan Guangpu , Liu Jing , Dong Suixin , Chen Yu
Published: May 2021

Objective: To evaluate the risk factors and explore the mid-term outcomes of postoperative atrial fibrillation (POAF) after minimally invasive direct coronary artery bypass (MIDCAB).
Methods: A total of 165 patients, who underwent isolated MIDCAB from 2012 to 2015, were enrolled in the study and retrospectively reviewed. Patients with preoperative arrhythmia, concomitant surgical procedures were excluded. All patients were continuously monitored for POAF until discharge, and two groups were formed: the non-POAF group (140 patients, 71.4% men, mean age 58.83±10.3 years) and the POAF group (25 patients, 84.0% men, mean age 64.52±9.0 years). Early and mid-term outcomes were evaluated, perioperative factors associated with POAF were analyzed with a binary logistic regression model, and the relationship between POAF and major adverse cardiac event (MACE) was analyzed with Cox regression model.
Results: The incidence of POAF in this study was 15.15%. Patients in the POAF group had a significant higher risk of re-entry to ICU (2 cases: 2 cases=8.0%: 1.4%, P = 0.049), renal failure (2 cases: 1 case=8.0%: 0.7%, P = 0.018), and death (1 case: 0 case=4.0%: 0%, P = 0.018). Binary logistic regression showed gender (male), age were independent risk factors of POAF (P = 0.038, 95% confidence interval 1.082-16.286; P = 0.011, 95% confidence interval 1.015-1.117, respectively), preoperative ACEI or ARB usage was a protective factor of POAF (P = 0.010, 95% confidence interval 0.113-0.748). With a 5-year follow up, the overall MACE rate showed no statistical difference between the two groups (P = 0.067).
Conclusions: POAF after MIDCAB was related to postoperative morbidities, such as re-entry to ICU, renal failure, and death. Gender (male) and age were independent risk factors, while preoperative ACEI or ARB usage was a protective factor. POAF has not associated the occurrence of MACE with a mid-term follow-up.

Background: Ventricular septal rupture (VSR) is a rare but lethal complication occurring after acute myocardial infarction. The aim of our study was to review the single-center experience of surgery for VSR and seek a comprehensive evaluation process for early mortality.
Methods: Patients undergoing surgical repair for postinfarction VSR in our institution retrospectively were evaluated from Jan. 2006 to Dec. 2019. The endpoint of the study was mortality within 30 days after VSR surgery, which was divided into survivors and nonsurvivors. The calibration and discrimination of two risk evaluation systems (European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) and the Society of Thoracic Surgeons (STS) risk score) in total were compared by Hosmer-Lemeshow, and the area under the receiver operating characteristic curve (AUC). Risk factors in subsets were assessed by logistic regression analysis.
Results: Twenty-three patients undergoing surgery for VSR repair were reviewed, and the early mortality after surgery was 34.8% (N = 8). The expected mortality predicted by EuroSCORE II was 24.3%, and that of the STS score was 12.2%. Both the EuroSCORE II and STS risk evaluation systems showed positive calibration in predicting mortality (H-L: P = 0.117 and P = 0.346, respectively) but poor discriminative power (AUC=0.633 and 0.575). Significant predictors determined by univariate analysis were concomitant coronary artery bypass grafting (CABG) (P = 0.035) and postoperative continuous renal replacement therapy (CRRT) (P = 0.008).
Conclusion: Early mortality of VSR after surgery remains high, and the evaluation process is complicated. The performances of the two risk evaluation systems were not optimal, but EuroSCORE II was more accurate than STS. Patients with lower preoperation EuroSCORE II, concomitant CABG during repair, and no need for CRRT after surgery may have a better early survival rate.
The Calm Before The Storm: The 4th Year of Medical School prior to a Surgery Residency

Many medical students figure that their fourth year of medical school should be a time primarily focused on residency interviews and resting up for residency. While the interview part is necessary, the concept that one should be resting during that year is a myth. In fact, nothing could be further from the truth. Your top priority should be to prepare yourself to hit the ground running as a great surgical intern.
Optimizing Conditions for the Measurement of Soil Inorganic Nitrogen with a Micro-Plate Reader

Published: May 2021

There are numerous methods for measuring inorganic nitrogen (N) in soils, but many of these are complex or require expensive equipment. In order to seek an accurate and rapid measurement method, we optimized the conditions for soil inorganic nitrogen (N) (NH4+-N and NO3–N) determination with a micro-plate reader; a systematic study was carried out. The effects of extraction regent concentrations, ratios of extraction solution to the soil, extraction time, extracted solution storage methods and time, and reaction time on soil inorganic N measurement were investigated. Results showed that all tested conditions except the storage method had a significant effect on the determination of soil NH4+-N and NO3–N. Compared with the non-stored treatment, the value of the measured soil nitrate-nitrogen increased after being stored in a refrigerator for seven weeks, while that for ammonium-nitrogen content was reduced. The appropriate protocol was using extracting solution directly to determine the content of NH4+-N and NO3–N in soil (otherwise, keep it at room temperature), 1.0 mol/L KCl as the extraction regent, solution/soil ratio with 10:1, extraction for 45 min, and reaction for 25 min (only for NH4+-N). The recovery rate of adding standard solution was above 99% as it met the detection requirements.

Мета: вдосконалити методику розвитку силових якостей дзюдоїстів 15-16 років з використанням динамічних вправ.

Матеріал і методи: аналіз науково-методичної інформації, джерел Інтернету та узагальнення провідного практичного досвіду, педагогічне тестування; хронометрування; педагогічний експеримент, методи математичної статистики. В педагогічному експерименті брали участь 20 дзюдоїстів, віком 15-16 років. Спортсмени були розділені на дві групи: контрольну та експериментальну по 10 дзюдоїстів в кожній. Педагогічний експеримент тривав три місяці (вересень – листопад 2020 р.).

Результати: на основі аналізу науково-методичної інформації і узагальнення передового практичного досвіду було виявлено, що рівень розвитку силових якостей значною мірою визначає тактико-технічну підготовку дзюдоїста, стиль і характер перебігу змагального поєдинку. Контрольна група займалася за навчальною програмою для ДЮСШ, а у дзюдоїстів експериментальної групи в тренувальному процесі застосовувалися комплекси динамічних вправ. Вправи розподілялися таким чином, щоб забезпечити чергування навантаження переважно для м’язів ніг, рук, спини, живота, загального впливу. На початку експерименту контрольні показники силових якостей між контрольною та експериментальною групами не виявили достовірно значущих відмінностей (р>0,05, значення t коливається від 0,32 до 1,01).

Висновки: у ході експерименту було встановлено, що використання комплексів динамічних вправ у тренувальному процесі позитивно впливають на силову підготовленість дзюдоїстів. Про це свідчать отримані результати наприкінці експерименту. Так, у дзюдоїстів експериментальної групи достовірно вище показники силової підготовленості майже у всіх тестах (р<0,05, значення t коливається від 2,10 до 2,34). В тесті «Учі-комі за 30 с» також результат краще у дзюдоїстів експериментальної групи, але він статистично недостовірний (t=1,07; p>0,05). Це пояснюється тим, що ця вправа є специфічною для дзюдо.

Мета: вивчення динаміки зміни показників координаційних здібностей кваліфікованих волейболісток під впливом використання комплексу вправ та рухливих ігор.

Матеріал і методи: у роботі використовувались наступні методи дослідження: аналіз науково-методичної літератури; педагогічний експеримент; педагогічне тестування; методи математичної статистики. Під час дослідження проведено педагогічний експеримент, який був спрямований на підвищення рівня координаційних здібностей кваліфікованих волейболісток. Для його проведення була обрана група з 10 кваліфікованих волейболісток віком 18-21 років команди «Харків’янка» (м. Харків), які приймають участь у змаганнях команд вищої ліги України. Для розвитку координаційних здібностей були запропоновані такі засоби як комплекс спеціальних вправ та рухливі ігри, а для їх оцінки були використані відповідні тести.

Результати: аналіз результатів педагогічного експерименту показав, що середньо арифметичні значення показників по кожному з чотирьох обраних тестів після проведення експерименту виявилися значно вищими у порівнянні з результатами відповідних тестів отриманих до початку експерименту. Результати відповідного порівняльного аналізу з використанням критерію Стьюдента довели достовірність різниці між значеннями показників цих тестів.

Висновки: запропоновані засоби для підвищення рівня координаційних здібностей волейболісток виправдали себе, як ефективні. Вони можуть застосовуватися тренерами команд в практичній роботі для підготовки гравців захисного амплуа, що сприятиме підвищенню результативності гри команди в тренувальній та змагальній діяльності.

Published: May 2021

A new minimization method of logic functions of n variables in polynomial set-theoretical format has been considered. The method based on the so-called “handshaking” procedure. This procedure reflects the iterative polynomial extension of two conjuncterms of different ranks, the Hamming distance between which can be arbitrary. The advantages of the suggested method are illustrated by the examples.
