Published: October 2021

Background. The majority of studies on the surgical treatment of chronic pancreatitis (CP) compare treatment outcomes by the type of the procedure. However, some studies, especially systematic reviews and meta-analyses, indicate the equality of different surgeries by their long-term results. During last 5–9 years, several studies showed advantages of early surgery in chronic pancreatitis, within three years after symptoms onset. Objective: to analyze the short- and long-term results of surgical treatment for chronic pancreatitis regarding timing and, accordingly, the neglect of the disease. Materials and methods. Retrospective analysis of data of 147 patients from 2001 to 2020, the main intervention was surgery aimed at the main manifestations of CP, such as pancreatic ductal and/or parenchymal hypertension. Patients who suffered from CP symptoms 3 years or more were included in the control group (late surgery), and those who noted symptoms of CP for less than 3 years were included in the study group (early surgery). All patients completed the EORTC QLQ-30, SF-36 questionnaires, as well as the questionnaire developed by the study authors, via telephone or mail, or during the visit. Results. According to all scales of the SF-36 questionnaire, except for Physical functioning, the group of early surgery prevails over the group of late surgery. The early surgery group had the best average scores on all functional scales of the EORTC QLQ-30 questionnaire compared to the late surgery group, except for the Cognitive functioning. Of the symptomatic scales, the early surgery group had the best averages on Pain and Diarrhea. The average Health/Quality of life scale was significantly better in the early surgery group. Conclusions. The quality of life, pain control, pancreatic function in patients operated within 3 years from the onset of CP symptoms were better compared to those with longer disease duration, with the same short-term results. The duration of the disease is a major factor for the success of surgical treatment of chronic pancreatitis in terms of long-term results. The early surgery is effective approach to obtain better long-term outcomes in chronic pancreatitis.

Abstract. This cross-sectional study analyzed by gender the association between body weight perception and weight control behavior with quality of life (QL) in 563 middle school students (age x̅ = 13.3, SD = 0.94), from all grades of nine middle schools of South region of Jalisco state realized in 2010. There were 51.9% boys and 19.8% worked. A self-administered questionnaire on line was used (YQOL-R), perceptual module, and five items of body weight adapted from 2009 Middle School YRBS. Statistical analysis included chi squared, Student t test, Spearman correlation, ANOVA and Tamhane ́s T2. Results: QOL was higher in normal weight perception category than low weight or overweight perception categories; a negative correlation between QOL and weight perception was observed (overweight rs = -.22; low weight rs = -.16); QOL was lower in those who tried to maintain weight in total sample and in girls in relation to those who tried to maintained it. We concluded that weight control behavior is associated with weight perception and both are associated with quality of life. Gender was important to understand the variables studied.

Published: October 2021

Abstract. The purpose of this review was to analyze the studies about psychometric properties of eating disorders (ED) questionnaires validated in Mexican women. We search papers published in scientific journal about psychometric properties of questionnaires to measure symptoms or characteristics associated with ED. Seventeen papers that evaluated the reliability or validity of 16 questionnaires were identified (11 were created in another countries and five were created by Mexican researchers). It was found that questionnaires have adequate reliability; however, the researchers only analyzed the internal consistency. Several methods were employed to analyze the validity of the questionnaires; the most common were factorial analysis exploratory and homogeneity of the scale. There are seven questionnaires with cut-off point, which permit to identify people at risk for ED. It was concluded that it is necessary that future researches provide further evidences about psychometric pro- perties of the revised questionnaires. Key words: Assessment, questionnaires, eating disorders, women, Mexico.   Resumen. El propósito de la presente revisión fue hacer un análisis de aquellos estudios en que se han examinado las propiedades psicométricas de instrumentos de evaluación de trastornos del comportamiento alimentario (TCA) en mujeres mexicanas. Se buscaron artículos publicados en revistas científicas sobre propiedades psicométricas de instrumentos para medir síntomas o características asociadas a los TCA. Se localizaron 17 publicaciones en las que se evaluó la confiabilidad y/o validez de 16 cuestionarios de autoinforme (11 creados en otros países y cinco construidos por investigadores mexicanos). Se encontró que los instrumentos poseen confiabilidad adecuada, sin embargo, sólo se ha analizado la consistencia interna. Para evaluar la validez de los instrumentos se han empleado diferentes procedimientos, siendo el más común el análisis factorial exploratorio y el análisis de la homogeneidad de la prueba. Siete de los instrumentos cuentan con punto de corte, el cual permite identificar a personas en riesgo de desarrollar algún TCA. Se concluyó que es necesario realizar más investigaciones que fortalezcan la evidencia existente sobre las propiedades psicométricas de los instrumentos revisados.

ABSTRACT Interventions based on mindfulness are increasingly used for feeding issues, looking for an improvement in the emotional regulation and awareness of internal states (i.e., satiety, hunger). The objective of this paper was to describe the perception of mindfulness when controlling binge eating behavior. A total of seven adults with binge eating behavior (20-52 years old), six women and one men participated in the study. All participants receive a training (workshop) about mindfulness and feeding. Based on a qualitative methodological approach with exploratory and descriptive scope, semi-structured interviews were performed pre-post intervention and were analyzed by open coding. Before intervention participants had no awareness in their relationship with food showing an automatic response. After intervention participants reported favorable changes such as increased of awareness as well as cognitive and emotional recognition, which led to changes in eating behavior. The participants made a positive evaluation of the workshop and the group format, highlighting that mindfulness was internalized as a new tool for daily life.RESUMEN  Intervenciones basadas en mindfulness (atención plena [AP]) están siendo cada vez más utilizadas para tratar temas alimentarios, buscando mejorar la regulación emocional y la conciencia acerca de los estados internos (e.g., hambre, saciedad). El objetivo de este trabajo fue describir la percepción de la práctica de la AP en el control de la conducta de atracón. Participaron siete adultos que presentaban conducta de atracón (20-52 años de edad), seis mujeres y un hombre. Como parte de este estudio, los participantes recibieron una intervención (taller) sobre AP y alimentación. Con base a un enfoque metodológico cualitativo, de alcance exploratorio y descriptivo, se realizaron entrevistas semiestructuradas pre-post intervención, las cuales fueron analizadas mediante codificación abierta. Antes de la intervención, los participantes sostenían una relación no consciente con la comida, presentando un modo de funcionar automático. Tras la intervención se reportaron cambios favorables, como el aumento de la conciencia y el reconocimiento cognitivo y emocional, lo cual supuso modificaciones en la conducta alimentaria. Los participantes realizaron una evaluación positiva del taller y del formato grupal, destacando que la AP fue interiorizada como una nueva herramienta para la vida diaria.

Abstract The objective of this study was to know the relationship between dietary intake (DI) and body composition (BC) with the metabolic syndrome (MS) among university students. A total of 50 students (56% female) among 19 and 25 years of age (M = 20.58, SD = 1.86), completed a questionnaire aimed at assessing DI, in addition biochemical and BC parameters were collected. According to the percentage of body fat (BF), a high prevalence of overweight (22%) and obesity (38%) was identified. In addition, visceral fat increased as the BF increased. In both sexes, there was a low consumption of carbohydrates and high in lipids, mostly of animal fat as well as high consumption of saturated fats, but low omegas 3 y 6. The MS was identified in 20% of the sample, mainly in women. The most frequently risk criteria were low levels of HDL cholesterol, followed by abdominal obesity; whereas the most frequent dyslipidemia was hypertriglyceridemia. In this study, although no direct relationship was found between DI and MS, it was found between MS and BC indicators. It is imminent the need to implement strategies that allow university students to acquire healthy eating and physical activity habits. Resumen El objetivo de este estudio fue conocer la relación de la ingesta alimentaria (IA) y la composición corporal (CMC) con el síndrome metabólico (SM) entre estudiantes universitarios.

Published: October 2021

Предложен и апробирован на примере полиэтилена высокой плотности, наполненного многослойными углеродными нанотрубками, новый полуэмпирический метод выделения вязкопластической компоненты из общей деформации ползучести. Метод основан на соотношении Эйринга для скоростей реакции и анализе результатов экспериментов на ползучесть в полулогарифмических координатах скорость деформации—деформация. Начальный линейный участок зависимости соответствует обратимой вязкоупругой деформации, а отклонение от линейности обусловлено появлением и развитием вязкопластической деформации. Вязкопластическая составляющая определяется простым вычислением с использованием четырех параметров аппроксимации двух линейных участков зависимости скорости деформации от общей деформации. Обобщенная зависимость вязкопластической составляющей от общей деформации получена с использованием результатов 57 испытаний на ползучесть разной длительности и при разных нагрузках образцов нанокомпозита с разным наполнением. Применимость метода подтверждена приемлемой корреляцией вычисленных значений вязкопластической деформации, накопленной в процессе ползучести, и остаточной деформации, определенной экспериментально на стадии обратной ползучести. Предложенный метод позволяет оценить вязкопластическую деформацию без проведения дополнительных испытаний на обратную ползучесть.

Низкая стойкость к ударам является одним из основных факторов, ограничивающих широкое внедрение композитов в конструкцию самолетов. При низкоскоростном ударе в композите возникают расслоения и межслойные повреждения, которые могут значительно снижать прочность конструкции и в определенных случаях требуют проведения ремонта. Индикаторные покрытия облегчают поиск места удара для дальнейшего неразрушающего контроля и характеристики дефектов в материале. В работе в качестве индикаторных покрытий рассмотрены световозвращающая акриловая пленка и эпоксидный композит на основе полых стеклянных микросфер. При ударе эти покрытия необратимо меняют коэффициент отражения, делая блестящую поверхность матовой в зоне отпечатка определенного диаметра. Образцы стеклопластика с покрытиями двух типов испытывали на низкоскоростной удар с разной энергией, после чего оценивали остаточную изгибную прочность. По результатам испытаний установлено, что диаметр отпечатка на покрытии зависит от энергии удара и может косвенно характеризовать остаточную прочность материала. Кроме того, установлено, что покрытие на основе полых стеклянных микросфер выступает в качестве бамперного слоя и снижает повреждения в композите при ударе.

Получены уравнения параметрического резонанса подкрепленной шпангоутами трехслойной цилиндрической оболочки с композитными слоями, внутри которой расположен пустотелый изотропный цилиндр. Оболочка нагружена осевыми силами и внешним давлением, гармонически изменяющимся во времени. Влияние цилиндра учитывается в виде упругого основания, коэффициент постели которого определяется из уравнений трехмерной теории упругости. Решение уравнений ищется в виде тригонометрического ряда по осевой координате. Полученная бесконечная система неоднородных дифференциальных уравнений типа Матье—Хилла решается с помощью тригонометрического ряда по временной координате. На числовом примере впервые получены главные области неустойчивости и приведены графические зависимости критических частот от радиуса канала и модуля упругости материала цилиндра, количества и высоты шпангоутов. Предложенная математическая модель расширяет круг решаемых актуальных научных и прикладных задач при исследовании трехслойных подкрепленных оболочек.

Published: October 2021

Objective: The present study aimed to investigate the difference in left
ventricular (LV) global and regional myocardial (MW) of strength
athletes with different heart rates (HR) through non-invasive LV
pressure-strain loop (PSL) and further address the effect of athlete’s
heart rate variability on the LV systolic function. Methods: Fifty young
professional wrestlers were collected randomly and divided into two
groups in accordance with their different HR: the low HR
(45~60 bpm, n=25) and the high
HR (60~80 bpm, n=25). Thirty
individuals with gender- and age-matched healthy volunteers served as
controls ( n=30). Global and regional MW
parameters were evaluated using LV-PSL derived from speckle tracking
echocardiography (STE) and brachial artery pressure, and then compared
between the above three groups. Results: The indicators of global and
regional MW did statistically significantly differ between the athlete
and control groups. Peak strain dispersion (PSD) and global myocardial
wasted work (GWW) increased while global myocardial work efficiency
(GWE) reduced in LHR and HHR groups compared with the control group, and
global myocardial work index (GWI), global myocardial constructive work
(GCW), global longitudinal strain (GLS) decreased in LHR group (
P＜0.05). In comparison to the LHR group, GWI, GCW, GWW, PSD
increased in HHR group and GWE reduced ( P＜0.05). According to
the regional MW analysis, the mean regional myocardial work index (RMWI)
increasing gradually from basal to apical levels were similar across the
three groups and regional myocardial work efficiency (RMWE) did not.
Multiple linear regression analysis indicated that the HR, posterior
wall thickness (PWT), interventricular septal thickness (IVST), GLS, and
PSD were correlated with GWE ( b’= -0.247, -0.390, -0.370, 0.340,
and -0.554, respectively, P＜0.05). Conclusions: The LV
contractile performance was more impaired in young strength athletes
with high heart rates and PSL can be used to assess LV GMW and RMW
quantitatively and accurately in reflecting LV systolic function.

Published: October 2021

Background/Aim. Rheumatoid arthritis (RA) is accompanied by numerous comorbidities, among which depression and anxiety (D/A) occupy a significant place. The aim of the study was to determine the prevalence of D/A in RA patients and the relationship with their quality of life (QoL). Methods. The study included RA patients treated at the Rheumatology Clinic of the Military Medical Academy in Belgrade, Serbia in the period from May to November 2016. Disease activity was assessed by the Disease Activity Score 28-SE (DAS28-SE). D/A was determined using the Hospital Anxiety and Depression Scale (HADS) questionnaire and European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L) questionnaire Question 5. Three questionnaires were used to assess QoL: the general RAND 36-item Health Survey 1.0 (RAND36), the specific Rheumatoid Arthritis Quality of Life Questionnaire (RAQoL) and EQ-5D-3L. Results. Based on the HADS questionnaire, the prevalence of depression was 52% with the average HADS score value of 7.6 ? 3.2, while the prevalence of anxiety was 32% with the mean HADS score value of 5.8 ? 3.8. Question 5 of the EQ-5D questionnaire showed that the prevalence of D/A was 77.4%, of which 71.7% of patients had moderate D/A, while 5.7% of patients had severe D/A. Impairment in all the domains of QoL was found in tested patients, as assessed by all three questionnaires. The RAQoL questionnaire showed moderate QoL impairment, with a score value of 15.5 ? 7.9. The EQ-VAS score value was 58.6 ? 16.0, while the EQ-5D index was 0.6 ? 0.3. Univariate linear regression produced a statistically significant negative predictive value of QoL for the presence of D/A. Multivariate linear regression showed a statistically significant independent negative predictive value of QoL, as assessed by the RAQoL questionnaire (p = 0.010) and the mental QoL component of the RAND 36 questionnaire (p = 0.030) for the degree of depression. Conclusion. In RA patients, there is a significant prevalence of D/A as well as impairment of QoL in all domains. The tests performed have shown that QoL has a statistically significant negative predictive value for the presence of D/A.

Objective:
Phenotypic heterogeneity among patients with type 2 diabetes mellitus (T2DM)
and atherosclerotic cardiovascular disease (ASCVD) is ill defined. We used cluster analysis machine
learning algorithms to identify phenotypes among trial participants with T2DM
and ASCVD.

Research
Design and Methods: We
used data from the Trial
Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS) study (n=14,671), a
cardiovascular outcome safety trial comparing sitagliptin with
placebo in patients with T2DM and ASCVD (median follow-up 3.0 years). Cluster analysis using 40 baseline
variables was conducted, with associations between clusters and the primary
composite outcome (cardiovascular
death,
nonfatal myocardial infarction, nonfatal stroke, or hospitalization for unstable
angina) assessed by Cox proportional hazards models. We replicated the results
using the Exenatide Study of Cardiovascular Event Lowering (EXSCEL) trial.

Results: Four distinct phenotypes
were identified: cluster I included Caucasian men with a high prevalence of
coronary artery disease; cluster II included Asian patients with a low body
mass index; cluster III included women with non-coronary ASCVD disease; and cluster
IV included patients with heart failure and kidney dysfunction. The primary
outcome occurred respectively in 11.6%, 8.6%, 10.3%, and 16.8% of patients in
clusters I to IV. The crude difference in cardiovascular risk for the highest
versus lowest risk cluster (cluster IV vs. II) was statistically significant (HR,
2.74; 95% CI, 2.29-3.29). Similar phenotypes and outcomes were identified in
EXSCEL.

Conclusions: In patients with
T2DM and ASCVD, cluster analysis identified four clinically distinct groups. Further
cardiovascular phenotyping is warranted to inform patient care and optimize
clinical trial designs.

Published: October 2021

Objective

To investigate the nature of the relationship between HbA1c and sepsis among individuals
with type 2 diabetes and to assess the association of sepsis and all-cause
mortality in such patients.

Research design and methods

We included 502,871
individuals with type 2 diabetes recorded
in the Swedish National Diabetes Register and used multivariable Cox regression and restricted
cubic spline analyses to assess the association between time-updated HbA1c
values and sepsis occurrence between
January 1, 2005 and December 31, 2015.
The association between sepsis and death was examined using multivariable Cox
regression analysis.

Result

Overall, 14,534
(2.9%) patients developed sepsis during the study period. On multivariable Cox
regression analysis, compared with an HbA1c of 48-52 mmol/mol (6.5-6.9%), the
adjusted hazard ratio for sepsis was 1.15 (95% CI 1.07-1.24) for HbA1c <43
mmol/mol (6.1%); 0.93 (0.87-0.99) for HbA1c 53-62 mmol/mol (7.0-7.8%); 1.05
(0.97-1.13) for HbA1c 63-72 mmol/mol (7.9-8.7%); 1.14 (1.04-1.25) for HbA1c
73-82 mmol/mol (8.8-9.7%); and 1.52 (1.37-1.68) for HbA1c >82 mmol/mol
(9.7%). In the cubic spline model, a reduction of the adjusted risk was observed
within the lower HbA1c range until 53 mmol/mol (7.0%), with a hazard ratio of 0.78
(0.73-0.82) per standard deviation, and increased thereafter (P for
non-linearity <0.001). As compared to patients without sepsis, the adjusted
hazard ratio for death among patients with sepsis was 4.16 (4.03-4.30).

Conclusions

In a nationwide cohort of individuals with type 2
diabetes, we found a U-shaped association between HbA1c and sepsis and a four-fold
increased risk of death among those developing sepsis.

To create a “golden course” means improving the quality of education and teaching, and cultivating high-quality talents. “Golden courses” require high-quality learning by college students. Many studies show that deep learning is a higher quality of learning. We study three teaching strategies to promote students’ deep learning. We use classroom space to awaken students' consciousness. We apply the Brubacher reflection model to improve students' reflective ability. We change the traditional teaching methods and guide students toward establishing a correct view of learning.

Published: October 2021

Since the 1990s, the unique image of Wong Kar-wai's films in the pattern of world cinema is getting more and more appealing throughout the world. Through the investigation of the status, role, identity and gender of Wong Kar-wai's films, we can find that Wong Kar-wai's films are a unique landscape of the auteur film in the context of Hong Kong's post-industrial and post-colonial society. Nowadays, more and more scholars have tried to combine Wong Kar-wai's films with philosophical and aesthetic theories when the world's diverse ideologies competed and disseminated. Then, the two philosophical theories of existentialism and film phenomenology have related connections about humans and nature, which have the opportunity to have a game-like theoretical interpretation with Wong Kar-wai's films, which may better unravel the inner flow of confusion and emotional tension of his films.

Based on Eduard Deci's self-determination and Kuhn's learning input and harvest theory, this paper constructs the conceptual model of the learning effect of normal school students in a blended teaching environment. The results show that basic psychological needs, blended teaching, autonomous learning motivation, and technology acceptance have significant positive effects on learning engagement, while controlled learning motivation has no significant effects on learning engagement. Based on this, it is proposed that more attention should be paid to normal students' controlled learning motivation in the blended teaching environment, so as to promote the effect of the course.

The Ethical Discourse: The Female Writing in the Modificated Process of For Jiao Zhongqing's Wife
Authors:   Academy of Chinese Studies, Beijing Language and Culture University, Xueyuan Road, Beijing, China, Xia Zhaoyang
Published: October 2021

In the early 20th century, the interpretation of the poem "Wei Jiao Zhongqing Qi Zuo" or "For Jiao Zhongqing's Wife" was mainly based on the social context at the time, which, however, might deviate from the original purpose of the female writing in the work. The poem once witnessed several modifications from the late Eastern Han Dynasty to the Southern Dynasties when the development of traditional Confucian code of ethics took off. The rewritings of female writing in literature works were to adapt to the male-dominated moral codes and discourse system at that time. Based on that, the female writing in the poem was processed, and evidence would be that from the perspective of content, the persona of Liu (Jiao's wife) portrayed in the poem changed greatly while characters like Jiao Zhongqing and Mother Jiao (Jiao's mother) were enriched. In addition, some new plots and characters were created for example, Brother Liu (Liu's brother) and Mother Liu (Liu's mother). In regard to the narrative strategy, the processed version intentionally emphasized the absence of "father" and "unrighteousness" of the brother to serve to the plot of suicide for love of Liu. This type of narrative poems conveying both criticism and praise was a tool used to complete and consolidate the ethical discourse and restrain women's influence on men, and it also echoed the traditional view of women passed from the Qin and Han Dynasties which for sure further confined women's free choice.

Published: October 2021

The purpose of this essay is to present the multiple patterns of the duplication sign at the mandibular fracture line/gap visualized at the panoramic radiography as two-line fracture gap or pseudocomminuted fracture. We retrospectively reviewed the orthopantomography of patients with mandible fractures and presented nine patients with 12 duplication signs (also known as lambda course fracture line). On panoramic radiographs the fracture line/gap with duplication sign is visualized as two-line cortical bone discontinuity with or without dislocation due to the fact that the fracture gap runs asymmetrically on the external and internal cortical plates of the jaw. Knowledge of duplication sign patterns, artifacts is also crucial for the precise diagnosis and choice of correct management strategy.
