Published: October 2020

Актуальность. Прогноз состояния природных ресурсов и изменений климата всегда актуален, так же как и поиск новых математических подходов. Анализ дендрохронологических и климатических временных рядов дает важную информацию для описания этих рядов, понимания, а также предсказания поведения рядов, характеризующих годичный прирост лесов, протекающих в них экологических процессов, а также климата в целом. Работы такого плана полезны и связаны с необходимостью сохранения заповедных лесных зон и развития лесной индустрии в целом. Цель: прогнозирование природных ресурсов и климата на основе выделения и использования многолетних трендов и тригонометрических составляющих известных характеристик: плотности годичных колец, изменений общего содержания озона в атмосфере, влияющего на уровень УФ-В радиации или УФ-В, и индекса аридности де Мортона, содержащего информацию о температуре и влажности лесных зон; представление исходных временных рядов в аддитивной форме в аналитическом виде. Объекты: временные ряды общего содержания озона в атмосфере, плотности годичных колец и индексов аридности де Мортона. Методы: анализ временных рядов (декомпозиция временного ряда, идентификация параметров модели, прогнозирование временного ряда), статистический анализ (F-критерий, - критерий Пирсона). Результаты. Произведен анализ дендрохронологических и климатических данных на предмет наличия тригонометрической компоненты. Это дало возможность получить сведения для прогноза температуры, осадков, ультрафиолет-B радиации, или УФ-В, и др. Получены аналитические выражения для тригонометрических составляющих максимальной плотности годичных колец, общего содержания озона, индекса аридности де Мортона. Совокупность тригонометрической составляющей и тренда позволяет получить достоверный прогноз и реконструкцию условий формирования годичных колец и плотности древесины. Прогнозные модели аппроксимации временных рядов тригонометрическим полиномом могут конкурировать с прогнозными моделями временных рядов спектрально-сингулярного разложения («Гусеница»).

The effect of music education on the social values of preschool children
Authors: Öztürk Erhan , Can Ajda Aylin
Published: October 2020

This study aims to explore the effect of music education on the acquisition of social values by preschool children. In this study, a quasi-experimental pattern model with the pretest–posttest control group is employed. The Preschool Social Values Scale is used for collecting the data. The participants of this study are 26 preschool children (the experimental and control groups contain 13 children each). Whilst the experimental group underwent 30 minutes of music training twice a week for 10 weeks, the control group pursued their preschool education. Music education with the experimental group consists of activities, where students are active and experience music. Songs containing social values were taught to children in the unity of play music and movement. At the end of the study, the scores related to the social values of the experimental group improved as compared to that of the control group. No meaningful difference was detected between the posttest and follow-up test social values’ scores.

The Impact of Parental Factors on Physical Aggression Perpetration among Turkish Urban Adolescents: The Mediating Role of Beliefs Supporting Aggression
Authors: Çetinkaya-Yıldız Evrim , Hatipoğlu-Sümer Zeynep
Published: October 2020

This study investigated parental factors and beliefs supporting aggression as predictors of physical aggression by adolescents. The participants were 2,443 junior high school students from Ankara, Turkey, who completed measures of parental support for aggression, family conflict, parental monitoring, beliefs supporting aggression, and physical aggression. The findings showed both direct and indirect effects of parental factors on physical aggression through beliefs supporting aggression. Furthermore, a multigroup model comparison indicated invariance of the structural relationships among variables in the model across gender and that the hypothesized structural model was a close fit for both the girl and the boy data. The findings suggest that it might be beneficial to consider beliefs supporting aggression and parental factors as risk factors when designing interventions to target physical aggression among adolescents.

Czytanie pamięci. Cisza, czas i emocje w opowiadaniach Idy Fink
Authors: Michułka Dorota , Świtała Sabina W. , Gregorowicz Łukasz
Published: October 2020

Ида Финк — автор сборников рассказов Обломки времени, Другие истории и следы, а также автобиографической повести Путешествие. Рассказы польскоязычной писательницы еврейского происхождения, cбежавшей в 1942 году вместе с сестрой из гетто Збаража, можно назвать душераздирающими, хотя она редко использует слово „смерть”, а ее повествованию чужды возвышенные эпитеты. Авторы статьи утверждают, что творчество Финк может быть проанализировано с перспективы теории памяти, поскольку представляет культуру воспоминаний. Финк говорит о Холокосте с точки зрения частных и индивидуальных свидетельств; она показывает социально-исторический контекст польско-еврейских отношений, изображает поведение людей перед лицом смерти. Анализируя рассказы Финк, авторы статьи приходят к выводу, что основными элементами повествования являются молчание и время. Когнитивное и эмпатическое чтение произведений Финк в школьной аудитории позволило показать, что рассказы Финк понятны молодой аудитории и хорошо ею воспринимаются.
Parateksty drukowanych ksiąg cerkiewnych w metropolii kijowskiej jako media pamięci (druga połowa XVI–XVII wiek)
Authors: Nowak Alicja Z.
Published: October 2020

Головним завданням паратекстів (листів-присвят, передмов тощо), якими зазвичай розпочиналися кириличні книги, надруковані у Київській митрополії, було уславлення меценатів цих видань. Здійснений у статті аналіз показує, що ці тексти розглядалися їхніми авторами як медіум пам’яті, опираючись на який будувалася колективна ідентичність тогочасного руського суспільства. Її основою було спеціально змодельоване бачення історії, яке ставало підґрунтям для інтерпретації та пояснення актуальних релігійних, культурних і навіть політичних подій.
Między pamięcią kulturową i paktem autobiograficznym. „Autobiografia filozoficzna“ Mikołaja Bierdiajewa
Authors: Dudek Andrzej
Published: October 2020

В тексте затрагивается вопрос особой формы духовной автобиографии, какой по намерению Н. Бердяева является его книга Самопознание (Опыт философской автобиографии). Философ считает, что его произведение в жанровом плане отличается как от классической автобиографии, так и от всех других разновидностей исповедальной литературы. Главная разница заключается в назначенной цели самопознания и осмысления собственной духовной жизни. Этот процесс проводится с учетом принципа сознательной подборки информационного материала о прошлом. В книге Бердяева осуществляются все 4 принципа автобиографического пакта, представленные Филиппом Леженом (повествование прозой, тема судьбы личности, идентичность автора и повествователя, идентичность повествователя и главного героя). Тем самым оказывается она преднамеренно субъективной попыткой воспроизведения культурного сознания современников русского философа. По мнению Бердяева, память — это активная, творческая стихия, которая осмысляет прошлое, позволяя интерпретировать его с точки зрения настоящего и с учетом перспективы вечности.
Rekonstruowanie pamięci. Problemy udostępniania ukraińskiej prozy lat dwudziestych i trzydziestych XX wieku polskiemu odbiorcy
Authors: Kotyńska Katarzyna
Published: October 2020

In the 1920s and 1930s novels and short stories crucial for understanding Ukrainian culture of the 20th century were written and published both in Soviet Ukraine and in Galicia. Such literary texts are essential in creating a comprehensive picture of Ukraine, as well as the Ukrainian-Polish relations. Because of politics and history, literary texts of the mature Ukrainian modernism were almost entirely unavailable in Polish translations. This paper discusses key historical, cultural and political reasons that have caused this situation. It also presents the new Polish scholarly and publishing projects aiming to familiarize Polish readers with Ukrainian modernism. In the conclusion, the author of the article mentions the current problems hindering the publication of the key Ukrainian novels and short stories of the 1920–1930s in Polish translations.
Role historické paměti v románech Viléma Hejla
Authors: Burget Eduard
Published: October 2020

Spisovateľ Vilém Hejl (1934–1989) napísal v šesťdesiatych a sedemdesiatych rokoch tri romány (Zásada sporu, Hodina hvězdopravců a Ex offo), ktoré vydal až po svojom odchodu z Československa v roku 1978 do exilu. Vo svojích prózach Hejl opakovane tematizoval úlohu pamäte na utváraní dejín, respektíve citlivo vnímal rozpor medzi pamäťou kolektívnou a individuálnou a z toho plynúcu problematickosť jednotného výkladu histórie. A to najmä v čase, keď by dejiny a pamäť mali slúžiť ako nástroj na presadenie určitého výkladu minulosti, ktorý by vyhovoval záujmom vládnuceho režimu, prípadne jeho odporcom.
Pamięć/wspomnienie. Uwagi do tekstu Lubomíra Doležela „Život s literaturou. Vzpomínky a rozhovory”

Studie se věnuje otázce poznávací hodnoty ego-dokumentu, jehož autorem je Lubomír Doležel, Život s literaturou. Vzpomínky a rozhovory (2013), vydaném jako šedesátý svazek v edici Paměť pražským nakladatelstvím Academia. Díky analýze textu dostáváme informace nezbytné pro vytvoření obrazu minulosti generace Čechů narozených před druhou světovou válkou, jako je duchovní atmosféra tohoto historického období, kterou nelze reprodukovat na základě jiných dokumentů. Pro naše účely se jednalo o náčrt reflexe části autobiografických závěrů Doležela, česko-kanadského lingvisty, teoretika literatury řazeného mezi zástupce třetí generace českého strukturalismu, generace spojené sdíleným prožitkem války a působící v podobném politicko-intelektuálním kontextu (dominance marxismu a strukturalismu). Jeho text je záznam jisté reality, záznamem a svědectvím viděných míst, potkaných osob, událostí, jichž byl svědkem, a zanecháním stopy po sobě a světě, ve kterém byl účastníkem.
Autoepitafium pisarza-celebryty — „Vladimír Páral o sobie i innych, ciekawszych sprawach”
Authors: Gwóźdź-Szewczenko Ilona
Published: October 2020

Vladimír Páral představuje v české literatuře druhé poloviny 20. století důležitou a výraznou osobnost, která se zřetelně odlišuje od jiných prozaiků té doby. Poetika jeho tvorby vyrůstá z tradice naturalismu, neorealismu a kritického realismu v české literatuře, přesto nikterak nelze jeho tvorbu zařadit do rámce libovolného zmíněného proudu. Sám spisovatel Vladimír Páral je považován svými příjemci za mistrného demaskátora své doby, za provokatéra bořícího tabu a přijaté společenské konvence, za postmodernistu, nebo za oblíbence socialistického režimu, ale i za tajemnou a živou legendu vyvolávající četné mravní skandály. Všechny tyto aspekty vedou k tomu, že knihu Profesionální muž nelze vnímat pouze v kategorii autobiografie autora, ale spíše jako další dílo spisovatelovy tvorby. Autor do jisté míry vytváří vlastní epitaf, v němž se snaží nasměrovat recepci celé své tvorby a rovněž upevnit svůj mýtus spisovatele-hédonisty.
Память о Византийской империи в романе „Жизнь насекомых” Виктора Пелевинa
Authors: Kidera Ritsuko
Published: October 2020

W dziełach Wiktora Pielewina często odnajdujemy korespondujące z sobą pojęcia „świata” i „całego świata”. Przedstawiony w ten sposób obraz rzeczywistości w powieści Życie owadów może nawiązywać do pamięci o Cesarstwie Bizantyjskim. Niniejszy artykuł poświęcony jest analizie tego zagadnienia na podstawie teorii Maurice’a Halbwachsa, której istotną częścią jest pojmowanie roli historii w pamięci zbiorowej.Pielewin ukazuje współczesną mu Rosję: atmosferę po rozpadzie Związku Radzieckiego oraz wpływ kultury amerykańskiej na życie jej mieszkańców. Pokazuje, że sytuacja kraju skłania jego obywateli do przemyśleń krążących wokół Bizancjum. Akcja powieści toczy się na Krymie, który pod pewnymi względami przypomina jego mieszkańcom Rzym, a koncepcja Rosji jako „Trzeciego Świata” wiąże się z ideą „Trzeciego Rzymu”. Motyw zaś Cesarstwa Bizantyjskiego towarzyszy historii zwykłych obywateli, którzy odwołując się do swojego życia osobistego, kreują własne wyobrażenie „całego świata”.
Pamięć. Rosja. Imperium. Fantastyka w aspekcie postkolonialnym
Authors: Polak Andrzej
Published: October 2020

Автор настоящей статьи относится к категории исторической памяти, памяти о империи как к одному из важнейших факторов формирования современной русской фантастики, прежде всего таких её жанров, как имперская фантастика, альтернативная история и социальная фантастика. Этот вопрос рассматривается с использованием понятий и методов, разработанных в рамках постколониальной теории. Популярность имперской темы обусловлена своеобразной для руcского общества памятью и тоской по империи (российской и советской), которую поддерживают общественно-политические и экономические явления (например, структурный кризис 1998 года, попытка восстановить великодержавность государства в XXI веке). Эти факторы приводят к заинтересованности фантастов имперским прошлым России и к рассматриванию альтернативных версий ее истории.

The potential of Neural Stem Cells (NSCs) to provide therapeutic benefit for a variety of neurologicaldisorders, including brain malignancies, has been long recognized and has inspired many scientists to design,test and successfully demonstrate that NSCs are efficient and effective therapeutic agents. Glioblastoma, thedeadliest form of primary brain tumor, despite extensive and sustained efforts to find better therapies, remainsa disease without cure, with a median survival after diagnosis of less than two years. Treatment resistance inglioblastoma is in large part attributed to limitations in the delivery and distribution of therapeutic agentsadministered either systemically or directly into the tumor due to the highly invasive nature of this cancer andits abnormal intratumoral vasculature. Stem Cells (SCs) have an innate tumor-tropic migratory behavior, canbe modified to deliver a variety of therapeutic agents and efficiently distribute their cargo into brain tumors,pursuing invading streams of tumor cells, deep into the brain parenchyma. Over the last twenty years,numerous preclinical trials have demonstrated the feasibility and efficacy of SCs as antiglioma agents, leadingto the development of trials to test these therapies in the clinic. In this review we present and analyze thesestudies and discuss mechanisms underlying their beneficial effect, highlighting experimental progress,limitations and the emergence of promising new therapeutic avenues. We hope to increase awareness of theadvantages of using SCs for the treatment of glioblastoma and inspire further studies that will lead toaccelerated implementation of effective therapies.

The coffee leaf miner (CLM) Leucoptera coffeella moth is a major threat to coffee production. Insect damage is related to the feeding behavior of the larvae on the leaf. During the immature life stages, the insect feeds in the mesophyll, triggering necrosis and causing loss of photosynthetic capacity, defoliation, and significant yield loss to coffee crops. Chemical control is mandatory to sustain the coffee production chain, though market requirements move towards conscious consumption, claiming for more sustainable methods. In this overview, we discuss aspects about the CLM concerning biology, history, geographical distribution, economic impacts, and the most relevant control strategies in progress. Insights to develop an integrate approach for a safer and eco-friendly control of the CLM are discussed, including bio-extracts, nanotechnology, pheromones, and tolerant cultivars.

This research examines the existence of a shift in functions in the family which is a function that causes some systems in the family structure to change resulting role dysfunction in family members. The research aims to obtain data on how the dysfunction in Kutorejo Village occurs. This research uses a qualitative approach to the type of descriptive research. Subject determination techniques use purposive sampling. The data sources used are primary and secondary data through researchers' notes, photographs, documents, books and other written resources. The data collection techniques are observation, interviews and documentation. This research uses Functional Structural Theory by Robert K. Merton which emphasizes regularity or order, ideas initiated by Merton include functions, manifests, latent functions and dysfunction. The results of this study state that what happens in the family cannot be separated from the role of parents. The helplessness of both parents who work as factory workers requires that the function should be executed precisely shifted to others, so that the main function of the family does not work as it should. This shows that there is a dysfunction of socialization that occurs.

Quadriceps Weakness After Single-Shot Adductor Canal Block
Authors: Yee Elliott J. , Gapinski Zachary A. , Ziemba-Davis Mary , Nielson Mark , Meneghini R. Michael
Published: October 2020

Background:

Adductor canal blocks (ACBs) are commonly employed in multimodal pain control for total knee arthroplasty (TKA) and minimize motor blockade compared with femoral nerve blocks. Quadriceps weakness may be associated with ACBs. The purpose of this study was to quantify the prevalence of clinically relevant quadriceps weakness after a single-shot ACB and to identify the factors that are associated with its diagnosis.

Methods:

The study group consisted of 1,083 retrospectively reviewed consecutive TKAs that were performed with ACBs at an academic hip and knee center. Quadriceps weakness was quantified with a standardized rating system during the initial physical therapy evaluation, and 23 potential covariates were analyzed.

Results:

The prevalence of quadriceps weakness was 9%. Increasing the dose of the ACB anesthetic per unit of body mass index (BMI) increased the probability of quadriceps weakness by 5.0 times (95% confidence interval [CI], 1.9 to 13.3; p = 0.001). The highest probability of quadriceps weakness (52.9%) was associated with women who received the highest anesthetic dose per unit of BMI and an epinephrine extender but no corticosteroid extender.

Conclusions:

The optimal volume of local anesthetic in ACBs to maintain pain control while minimizing quadriceps weakness has not yet been defined. Our observation that quadriceps weakness was associated with increasing doses of ACB anesthetic per unit of BMI suggests that more than traditional structural canal-fill parameters (i.e., filling the distal aspect of the adductor canal without spreading to the femoral triangle) should be considered when choosing injectates and injectate volumes for ACBs.

Level of Evidence:

Background:

Despite the extensive use of cellular bone matrices (CBMs) in spine surgery, there is little evidence to support the contribution of cells within CBMs to bone formation. The objective of this study was to determine the contribution of cells to spinal fusion by direct comparisons among viable CBMs, devitalized CBMs, and cell-free demineralized bone matrix (DBM).

Methods:

Three commercially available grafts were tested: a CBM containing particulate DBM (CBM-particulate), a CBM containing DBM fibers (CBM-fiber), and a cell-free product with DBM fibers only (DBM-fiber). CBMs were used in viable states (CBM-particulatev and CBM-fiberv) and devitalized (lyophilized) states (CBM-particulated and CBM-fiberd), resulting in 5 groups. Viable cell counts and bone morphogenetic protein-2 (BMP-2) content on enzyme-linked immunosorbent assay (ELISA) within each graft material were measured. A single-level posterolateral lumbar fusion was performed on 45 athymic rats with 3 lots of each product implanted into 9 animals per group. After 6 weeks, fusion was assessed using manual palpation, micro-computed tomography (μ-CT), and histological analysis.

Results:

The 2 groups with viable cells were comparable with respect to cell counts, and pairwise comparisons showed no significant differences in BMP-2 content across the 5 groups. Manual palpation demonstrated fusion rates of 9 of 9 in the DBM-fiber specimens, 9 of 9 in the CBM-fiberd specimens, 8 of 9 in the CBM-fiberv specimens, and 0 of 9 in both CBM-particulate groups. The μ-CT maturity grade was significantly higher in the DBM-fiber group (2.78 ± 0.55) compared with the other groups (p < 0.0001), while none of the CBM-particulate samples demonstrated intertransverse fusion in qualitative assessments. The viable and devitalized samples in each CBM group were comparable with regard to fusion rates, bone volume fraction, μ-CT maturity grade, and histological features.

Conclusions:

The cellular component of 2 commercially available CBMs yielded no additional benefits in terms of spinal fusion. Meanwhile, the groups with a fiber-based DBM demonstrated significantly higher fusion outcomes compared with the CBM groups with particulate DBM, indicating that the DBM component is probably the key determinant of fusion.

Clinical Relevance:

Data from the current study demonstrate that cells yielded no additional benefit in spinal fusion and emphasize the need for well-designed clinical studies on cellular graft materials.

Published: October 2020

Background: To identify the applicability of the Chinese Version of Mattis Dementia Rating Scale (DRS-CV).Methods: The DRS-CV was administered to 483 participants, including 136 normal controls, 167 patients with mild cognition impairment (MCI), and 180 patients with Alzheimer’s disease (AD). Receiver Operating Characteristic (ROC) curve was used to evaluate the sensitivity and specificity of the scale.Results: The scores of DRS-CV were ranked in the order of NC >MCI > mild AD > moderate AD group. Memory was the sensitive function affected at a relatively earlier stage of AD. ROC curve analysis indicated the DRS-CV total score and memory subscale showed excellent sensitivity and specificity in the discrimination between MCI from mild AD and mild AD from moderate AD, but poor sensitivity and specificity in the discrimination between MCI and NC.Conclusion: The DRS-CV is useful to the early diagnosis and severity of AD, not to the early identification of MCI.

Background: Posterior canal benign paroxysmal positional vertigo (pc-BPPV) causes physical, functional, and emotional impairment. The treatment of choice is the Epley manoeuvre (EM). The purpose of the study was to compare the impact of the EM and a sham manoeuvre in primary care on self-perceived disability. Method: Randomised, double-blind, sham-controlled clinical trial conducted in primary care with a follow-up of 1 year. Patients aged ≥18 years old diagnosed with pc-BPPV according to the Dix-Hallpike test (DHT) were randomised to an intervention (EM) group or a control (sham manoeuvre) group. The main study covariables were age, sex, history of depression and anxiety, presence of nystagmus in the DHT, patient-perceived disability assessed with the Dizziness Handicap Inventory-screening version (DHI-S). Data were analyzed using bivariate and multivariate mixed Tobit analyses. Results: Overall, 134 patients were studied: 66 in the intervention group and 68 in the control group. Median age was 52 years (interquartile range [IQR], 38.25–68.00 years) and 76.12% of the patients were women. The DHT triggered nystagmus in 40.30% of patients. The median total DHI-S score for the overall sample at baseline was 16 (IQR, 8.00–22.00); 16 [IQR, 10.5–24.0] vs 10 [6.0–14.0] for women vs men ( P <0.001) and 16 [IQR, 10.0-24.0] vs 12 [IQR, 8.0–18.0] for patients without nystagmus vs those with nystagmus ( P =0.033).Patients treated with the EM experienced a mean reduction of 2.03 points in DHI-S score over the follow-up period compared with patients in the sham group. Conclusion: Pc-BPPV affects the quality of life of primary care patients. A single EM can improve self-perceptions of disability by around 2 points on the DHI-S scale, Trial registration : ClinicalTrials.gov Identifier: NCT01969513. Retrospectively registered.

The relationship between time to surgery after neoadjuvant chemotherapy and survival in breast cancer patients:a meta-analysis
Authors: Su YongCheng , Zheng XiaoGang
Published: October 2020

PURPOSE: This meta-analysis aims to evaluate the impact of delaying surgery in operable breast tumor patients after neoadjuvant chemotherapy (NAC) on survival. METHODS:An electronic literature retrieval was conducted on PubMed/Medline and EMBASE((between January 2000 and June 2020).The primary end point was overall survival(OS),secondary end points included disease-free survival (DFS) or recurence-free survival (RFS).The HR with 95% confidence intervals were calculated using a random-effects or fixed-effects model. RESULTS:The combined HR for OS was 1.51 (95% CI:1.30-1.76; P=0.000) by fixed effects model.No statistically significant heterogeneity was found (P=0.168, I 2 =31.3%).The pooled HR for RFS/DFS was 1.59 (95%CI:1.30-1.95,I 2 = 66.0%) by random-effects model,with significant heterogeneity. CONCLUSION:Our meta-analysis revealed a significant adverse association between longer TTS after NAC and more inferior OS and RFS/DFS in patients with breast cancer.Clinicians and patients should minimize surgical delay after NAC as much as possible.
Student Lecture Attendance and Its Relation to Exam Performance in the Era of Lecture Capture Technology.
Authors: Powers Claud A , Carroll Mairead A.
Published: October 2020

Background: Students can now review on-line lecture recordings rather than attend lectures. However, there is little data on the fraction of students attending lectures, the patterns of attendance, or the ultimate learning outcomes. To study this issue, attendance data was used to compare learning outcomes of students with different patterns of attendance.Methods: A retrospective observational analysis was performed using data collected in the Medical Pharmacology course in Fall 2013 (197 students) and Fall 2014 (207 students). Attendance was monitored at 13 of 40 lectures with an audience response system in each semester. All lectures were recorded using lecture-capture, and students could attend lectures or review online recordings and PowerPoint files as desired. Exam averages of students in different attendance categories were compared, along with the frequency distribution of exam scores in the different attendance categories. Results: In the years studied, 12-14% of the students had a consistent pattern of high attendance at monitored lectures; 35-46% of the students had an erratic pattern of low to intermediate attendance, and 41-52% of the students did not attend any monitored lectures. Aggregate exam averages of students with >80% attendance were over 5 percentage points higher than those of students in other attendance categories (P<0.05 using t-tests or ANOVA). Students with >80% attendance also displayed a significant shift in aggregate exam averages to higher ranks in frequency distribution analyses (P<0.05 using Chi-Square tests). Exam averages of students with low to intermediate attendance did not differ from students with no attendance. The scoring advantage associated with >80% lecture attendance remained evident 20 weeks after the Fall semester when students took a comprehensive pharmacology examination (P<0.05). Conclusions: On average, students with a consistent pattern of high lecture attendance had higher exam scores than students with low to intermediate or no attendance who had access to the identical course material on-line. This may reflect factors related to the method of content acquisition (live vs. on-line) or differences in the learning readiness of students choosing one approach vs. another. The data suggest that curricular changes that encourage consistent lecture attendance might improve learning outcomes for some students.

Published: October 2020

Background

Coronavirus disease 2019 (COVID-19) has spread around the world and caused many deaths, but little is known about the risk factors for death in critically patients.
Methods

we collected demographic and clinical data on all severe inpatients with COVID-19 .We used univariable and multivariable Cox regression methods to determine the independent risk factors related to likelihood of 28-day and 60-day survival, performing survival curve analysis.
Results

Of 325 patients enrolled in the study, Multi-factor Cox analysis showed increasing odds of in-hospital death associated with basic illness (hazard ratio [HR] 6.455, 95% Confidence Interval [CI] 1.658–25.139, P = 0.007), lymphopenia (HR 0.373, 95% CI 0.148–0.944, P = 0.037), higher Sequential Organ Failure Assessment (SOFA) score on admission (HR 1.171, 95% CI 1.013–1.354, P = 0.033) and being critically ill (HR 0.191, 95% CI 0.053–0.687, P = 0.011). Increasing 28-day and 60-day mortality, declining survival time and more serious inflammation and organ failure were associated with lymphocyte count ≤ 0.8 × 109/L, SOFA score > 3, Acute Physiology and Chronic Health Evaluation II (APACHE II) score > 7, PaO2/FiO2 ≤ 200 mmHg, IL-6 > 120 pg/ml, and CRP > 52 mg/L.
Conclusions

Being critically ill and lymphocyte count, SOFA score, APACHE II score, PaO2/FiO2, IL-6, and CRP on admission were associated with poor prognosis in COVID-19 patients.
The value of lymph node ratio and total number of lymph nodes examined for resected pancreatic signet ring cell carcinoma: a retrospective cohort study
Authors: Ren Chao , Xue Feng , Wu Yinying , Wang Zheng
Published: October 2020

Background—Pancreatic signet ring cell carcinoma (SRCC) was an exceedingly rare histological subtype of pancreatic cancer. Previous studies focused on the trends of incidence and independent predictors of pancreatic SRCC. Our objectives of the study was to analyze the prognostic value of lymph node ratio (LNR) and explore the minimal number of lymph nodes examined to accurately evaluate the N stage in resected pancreatic signet ring cell carcinoma.Method—The data diagnosed from January 1, 1990 to December 31, 2016 constituted the study cohort from the Surveillance, Epidemiology, and End Results(SEER) registry. We calculated overall survival (OS) of these patients using Kaplan–Meier analysis and Cox proportional hazards model and used receiver-operating characteristic curve (ROC) analysis to investigate the discriminatory ability of the total number of lymph nodes examined(TNLE) relative to whether lymph node metastasis.Results—The median number of lymph nodes examined among 120 patients of resected pancreatic SRCC was 14 (interquartile range, 6.25 to 20.0).According to the univariate analysis of overall survival(OS) result, age, grade, chemotherapy, LNR and TNLE were significantly different(P<0.05).Multivariate survival analysis showed that LNR and grade were the independent prognostic indicators after pancreatic SRCC resection for OS. TNLE ≥ 8 showed the highest discriminatory power to evaluate whether the lymph node metastasis (AUC 0.656, 95%CI 0.564-0.741, Youden index 0.2533, sensitivity 78.67%, specificity 46.67%, P= 0.003)Conclusion—Our study indicated that LNR was a valuable independent prognostic factor for resected pancreatic SRCC. Regional lymphadenectomy of at least 8 lymph nodes was necessary to stage patients accurately. Enough number lymph nodes examined was necessary for the clinicians to accurately predict the significance of LNR in resected pancreatic SRCC.
