Abstract
Aim: To assess the knowledge, attitudes, and behavior of a group of mothers with their children aged 6-12 years regarding their own and their children’s oral health and to evaluate its impact on their children oral health status in Jeddah, Saudi Arabia. Methods: A validated, and reliable Arabic questionnaire comprised four sections (demographic characteristics and socioeconomic status, Hiroshima University– Dental Behavioral Inventory; HU-DBI; for mother’ attitudes and behavior pertaining their own oral health, mothers’ knowledge, and mothers’ attitudes regarding oral health of their children) was used for this study. The questionnaire was completed by the mothers. A clinical oral examination was performed for the children, attending primary schools in Jeddah city, to detect the caries experience and Simplified Oral Hygiene Index (OHI-S). Results: A total of 1496 mother-child pairs completed the study. The mean values of dmft were 4.08 ± 3.47; DMFT was 1.82 ± 2.07; total dmft and DMFT was 5.65 ± 4.05; and the OHI-S was 1.17 ± 0.94. According to the questionnaire results, mothers in private schools had a more favorable attitude and behavior toward their own oral health, as well as a more favorable knowledge and attitude toward their children's oral health. The multiple linear regression model revealed that the children's dmft/DMFT scores were significantly related to mother education, mother questionnaire scores, and the OHI-S. Conclusion: Mother education, knowledge, and attitude all play a role in the development of dental caries. Overall, mothers need to improve their oral health attitudes and behaviors, as well as increase their level of oral health knowledge.

Abstract
Background: The relationship between immunonutritional status (eg. Prognostic nutritional index [PNI] and Controlling Nutritional Status [COUNT] score) and risk of postoperative pulmonary complications (PPCs) after surgical resection of lung cancer had reported before. However, another immunonutritional parameter- Geriatric Nutritional Risk Index (GNRI)-had never explored.Method: To address this issue, in this study we retrospectively analyzed patients’ characteristics and PPCs in a cohort of lung cancer patients who were treated by surgical resection at our center. The clinical utility of patients’ characteristics for predicting PPCs was evaluated by receiver operating characteristic curve analysis and the Youden index. Univariate and multivariate analysis were applied to find the most important factors.Result: A total of 128 patients met the inclusion criteria for this study. Significant differences in sex, GNRI, FEV1%, LY% were found between the PPC and non-PPC groups (all P<0.05). The difference in pathology between the 2 groups showed borderline statistical significance (P=0.052). We determined the best cutoff value of each parameter and calculated the corresponding sensitivity and specificity, and found that GNRI, FEV1% and LY% had similar diagnostic value. Multivariate analysis reveled GNRI, sex, LY% and FEV1% were filtered to be correlated to PPCs of elderly lung cancer patients received surgery therapy.Conclusion: These results indicate that preoperative immunonutritional parameters of GNRI can be used to identify elderly lung cancer patients at risk of PPCs.

Abstract
Background: Total-body dynamic PET (dPET) imaging using 18F-fluorodeoxyglucose (18F-FDG) has received widespread attention in clinical oncology. However, the conventionally required scan duration of approximately one hour seriously limits the application and promotion of this imaging technique. In this study, using Patlak analysis-based Ki parametric imaging as the evaluation standard, we investigated the possibility and feasibility of shortening the total-body dynamic scan duration to 30 mins post-injection (PI) with the help of a novel Patlak data processing algorithm.Methods: Total-body dPET images acquired by uEXPLORER (United Imaging Healthcare Inc.) using 18F-FDG of 15 patients with different types of tumors were analyzed in this study. Dynamic images were reconstructed into 25 frames with a specific temporal dividing protocol for the scan data acquired one hour PI. Patlak analysis-based Ki parametric imaging was carried out based on the imaging data corresponding to the first 30 mins PI, during which a Patlak data processing method based on third-order Hermite interpolation (THI) was applied. The resulting Ki images and standard Ki images were compared in terms of visual imaging effect and Ki estimation accuracy to evaluate the performance of the proposed data processing algorithm for parametric imaging with dPET with a shortened scan duration.Results: With the help of Patlak data processing, acceptable Ki parametric images were obtained from dPET data acquired with a shortened scan duration. Compared to Ki images obtained from unprocessed Patlak data, the resulting images from the proposed method contained less image noise, leading to remarkably improved imaging quality. Moreover, box plot analysis showed that that 30-min Ki images obtained from processed Patlak data have higher accuracy regarding tumor lesion Ki values.Conclusion: Acceptable Ki parametric images can be acquired from dynamic imaging data corresponding to the first 30 mins PI. Patlak data processing can help achieve higher Ki imaging quality and higher accuracy regarding tumor lesion Ki values. Clinically, it is possible to shorten the dynamic scan duration of 18F-FDG PET to 30 mins to facilitate the usage of such imaging techniques on uEXPLORER scanners.

Abstract
Background: The aim of this study is to analyze the role of neutrophil-lymphocyte ratio and its variation pre and post-operatively (delta NLR) in overall survival after pancreatectomy for pancreatic ductal adenocarcinoma at a single centre and to identify factors associated with overall survival.Methods: A retrospective study of consecutive patients undergoing pancreatic resection due to PDAC or undifferentiated carcinoma from January 2010 to January 2020 was performed. Association between evaluated factors and overall survival were analyzed using a log-rank test and Cox proportional hazard regression model.Results: ﻿Overall, 242 patients underwent complete pancreatic resection for PDAC or undifferentiated carcinoma. OS was 22.8 months (95% CI: 19.5-29) and survival rates at 1, 3 and 5 years were 72%, 32.5% and 20.8% respectively. NLR and delta NLR were not significantly associated with survival (HR=1.14, 95%CI: 0.77-1.68, p=0.5). Lymph node ratio was significantly associated (HR=1.66, 95%CI: 1.21-2.26, p=0.001) in the bivariate analysis. In multivariable analysis the only factors that were significantly associated with survival were perineural invasion (HR=1.94, 95%CI: 1.21-3.14, p=0.006), surgical margin (HR=1.83, 95%CI: 1.10-3.02, p=0.019), tumor size (HR=1.01, 95%CI: 1.003-1.027, p=0.16), postoperative CA 19-9 level (HR=1.001, p<0.001), and completion of adjuvant treatment (HR=0.53, 95%CI: 0.35-0.8, p=0.002).﻿Conclusion: Neutrophil-lymphocyte ratio and delta NLR were not associated with overall survival in this cohort. Risk factors such as perineural invasion, surgical margins, CA19-9 level and tumor size showed worse survival in this study, whereas completing adjuvant treatment was a protective factor.

Abstract
In this paper we provided methods for investigating the injectivity of linear bounded operators on separable Hilbert spaces using their approximations on dense families of subspaces. As an application we proved the injectivity of the integral operator involved in the equivalent formulations of Riemann Hypothesis (see [2] and [4]) in the Example 4.2.

Published: December 2021

Abstract
Objective: Metabolically healthy obesity (MHO) is a dynamic condition and is known to increase the risk for chronic kidney disease (CKD). In this study, we aimed to examine the association between metabolic health status and its change over time and CKD risk.Methods: A total of 39463 participants from Kailuan Study were collected body mass index and metabolic health status at 2006/07 and 2010/11 examination. Metabolic abnormality was diagnosed by the presence of any 2 of 4 components (elevated blood pressure, elevated fasting blood glucose, elevated triglyceride and decreased high-density lipoprotein cholesterol). We classified participants into six groups according to metabolic health status and obesity. The changes in obesity and metabolic health status were considered from 2006/07 to 2010/11. Results: Of the participants classified as MHNW or MHO at baseline, 17.25% and 39.64% were classified as MUNW or MUO in 2010/11, respectively. During a mean follow-up of 9.7 years, 5351 participants developed CKD from 2010/11. Compared with participants in the stable MHNW group, the stable MHO group had a significantly higher risk of incident CKD (HR: 1.16; 95% CI: 1.02-1.33), but was lower than that in individuals with MUO. Individuals with metabolic healthy at baseline who changed to metabolic abnormality during follow-up had higher risk of CKD. Conclusions: MHO phenotype or its transition to a metabolically unhealthy phenotype were associated with increased risk of CKD. Stable metabolic health individuals had lower risk of CKD than those with metabolically unhealthy phenotype.

Abstract
The recently discovered AV3Sb5 (A=K, Rb, Cs) family, possessing V kagome nets, has received considerable attention due to the topological electronic structure and intriguing correlated phenomena, including an exotic charge density wave (CDW) and superconductivity. Detailed electronic structure studies are essential to unravel the characteristics and origin of the CDW as well as its interplay with superconductivity. Here, we present angle-resolved photoemission spectroscopy (ARPES) measurements for CsV3Sb5 at multiple temperatures and photon energies to reveal the nature of the CDW from an electronic structure perspective. We present evidence for a three-dimensional (3D) CDW order. In the process we also pinpoint a surface state attributed to a Cs terminated surface. This state was previously attributed to band folding band due to a CDW along the c direction or a quantum well state from quantum confinement. The CDW expected 2-fold lattice reconstruction along c axis is observed to be a quadrupling of the unit cell, thus for the first time directly demonstrating the 3D nature of the CDW from the electronic structure perspective. Moreover, this 3D CDW configuration originates from two distinct types of distortions in adjacent kagome layers. These present results not only provide key insights into the nature of the unconventional CDW in CsV3Sb5 but also provides an important reference for further studies on the relationship between the CDW and superconductivity.

Abstract
Background The survival rate of patients with hepatoblastoma (HB) with distant metastases is unsatisfactory. Although dose-dense chemotherapy with a high incidence of ototoxicity improves the prognosis of these patients, surgical metastasectomy may provide an alternative treatment option avoiding drug side effects. The aim of this study was to examine the efficacy of “complete” pulmonary metastasectomy for the treatment of children with metastatic HB. Methods This retrospective study retrieved data from 2004 to 2015 on 22 children with metastatic HB. Separated into two groups; children who underwent only hepatectomy (group H, 14 cases), and children who underwent primary or rescue liver transplantation (group T, eight cases). Each patient was administered initial chemotherapy according to JPLT-2, SIOPEL3 or PLADO protocols. Over the course of this study, we performed metastasectomies for all detectable pulmonary metastases. Indocyanine green fluorescent navigation was used for 15 patients to detect tiny metastases. The follow-up period for survivors after the last metastasectomy ranged from 36 to 186 months. Results The cumulative disease-free 5-year survival rate was 84% in group H and 33% in group T. The median number of resected pulmonary metastatic lesions was 10.5 (range: 1-42) in group H and 3.5 (range: 1–97) in group T. None of the survivors developed hearing or respiratory impairment. Conclusions Complete pulmonary metastasectomy improves the prognosis of patients with metastatic HB with conventional chemotherapy, especially in the patients with primary HB lesions removed without liver transplantation.

Published: December 2021

Abstract
Background: Total knee arthroplasty (TKA) is a highly complex and effective surgery even though its perioperative bleeding may increase the need for blood transfusion and its associated infection risk, cardiovascular overload, increased costs, and mortality. As tourniquet reduces intraoperative bleeding it may be associated with postoperative bleeding, venous thrombosis, and distal ischemia. The reperfusion may trigger a local and systemic inflammatory response. Anesthetic preconditioning (APC) with sevoflurane minimizes ischemia-reperfusion syndrome (I/R). This study evaluated the effects of APC with sevoflurane on perioperative bleeding in TKA.Methods: We allocated 30 patients into two groups: a sevo group (sevoflurane 2% for 15 minutes before the tourniquet) and a control group (propofol infusion). Laboratory tests were collected right before the tourniquet (LAB PRE, in the operating room) and after its release at four moments: LAB POST (immediately after), LAB 2 (two hours after), LAB 12 (12 hours after), and LAB 24 (24 hours after). The volume of the suction drain was measured at one, two, 12, and 24 hours after the end of the surgery. Antifibrinolytics were not administered.Results: There was no statistically significant difference in bleeding-related variables, such as drained volume and hemoglobin and hematocrit measurements. Drainage volume was higher in the first two hours after the procedure, while hematocrit decreased pre- to post-operatively and between two- and 12-hours post-procedure.Conclusion: Sevoflurane as an anesthetic preconditioning did not reduce postoperative bleeding in TKA surgery.Trial Registration: ClinicalTrials.gov – NCT03379103; December 20, 2017.

Abstract
How to derive the accurate value of temperature integral is a vital problem for the non-isothermal kinetic analysis. In the past six decades, researchers provided various methods to solve above problem, but the error usually becomes divergent when the value of x (x=Ea/RT) is too small or too large, no matter whether it is a numerical method or an approximation method. In this paper, we present a new series method and elaborately design a computer program to calculate the value of temperature integral. Finally, we reveal the mysterious relationship between the integral, the temperature and the activation energy, and we find an extremely interesting phenomenon that the 3-D image of the temperature integral is of self-similarity according to the fractal theory.
BREVE CONTEXTUALIZAÇÃO DA ATUAL CONFIGURAÇÃO DA DEPENDÊNCIA LATINO-AMERICANA E A ECONOMIA MUNDIAL CAPITALISTA: UMA AGENDA DE DEBATES
Authors: Trindade José Raimundo Barreto 
Published: December 2021

A Teoria da Dependência (TD) surgiu em meados da década de 1960, em parte como uma reação ao aparente fracasso da análise e das propostas dos desenvolvimentistas e em grande medida como tentativa de explicar as novas características do desenvolvimento socioeconômico da região. Os teóricos da dependência argumentavam que a estratégia de industrialização baseada na substituição das importações era incapaz de produzir efeitos de ruptura com o subdesenvolvimento, pois o mesmo seria antes de tudo uma consequência e parte do processo de expansão mundial do capitalismo. O artigo tem como objetivo central retomar a teoria da dependência enquanto aporte teórico robusto que colabora na interpretação contemporânea das sociedades latino-americanas e se propõe a estabelecer pontos de uma agenda de pesquisa centrada na atualidade e atualização deste aporte teórico. Inicialmente abordam-se os elementos históricos e categoriais sobre e da teoria da dependência; posteriormente, trata da relação entre a teoria da dependência marxista e sua interpretação do contexto latino-americano, buscando compreender as condições de manutenção e renovação da dependência latino-americana; por fim, propomos uma agenda de pesquisas e trabalhos, o que se mostra tanto profícuo, quanto necessário na presente conjuntura de instabilidade e de retrocessos sociais manifestos no Brasil e na América Latina.
Inspiracje sztuką i kulturą Podhala w powojennej galanterii i biżuterii polskiej
Authors: Myśliński Michał 
Published: December 2021

Abstrakt:
Zainteresowanie sztuką ludową Podhala wśród polskich artystów i badaczy sięga lat osiemdziesiątych XIX wieku. Wynikało ono z dostrzeżenia artystycznej wartości tworzonych tam dzieł oraz poszukiwań tzw. sztuki narodowej i rodzimej, tak bardzo ważnych dla polskiej kultury i tożsamości. Inspiracje kulturą materialną i artystyczną Podhala przyczyniły się m.in. do wielkiego sukcesu polskiej ekspozycji na Wystawie Sztuki Dekoracyjnej w Paryżu w 1925 roku.
Zainteresowanie to nie zmniejszyło się po 1945 r., ale przybrało inne formy. W tym czasie powstawały w Polsce liczne spółdzielnie, których zadaniem było tworzenie przedmiotów codziennego użytku i dzieł sztuki ludowej, zgodnie z lokalną tradycją rękodzielniczą, ikonograficzną, zdobniczą itp. Pewną część produkcji stanowiła tzw. metaloplastyka – sprzączki do pasków, spinki do koszul, zatrzaski do torebek, noże, okucia fajek i in., których forma była inspiracją dla artystów tworzących dzieła biżuterii – bransoletki, broszki, wisiory itp. Asortyment ten uzupełniony został także o inne elementy – wykonywane z blachy, kości bydlęcej, galalitu i drewna broszki, wisiorki i breloki, które były przede wszystkim pamiątkami przywożonymi z tego bardzo popularnego regionu turystycznego.
Summary:
The interest in the folk art of the Podhale region among Polish artists and researchers dates back to the 1880s. It resulted from the perception of the artistic value of the works created here, as well as the search for the so-called national and native art, very important for Polish culture and national identity. Inspiration with the material culture of Podhale came from, among others a great effect in the form of the success of Polish art at the Exhibition of Decorative Art in Paris in 1925.
This interest did not diminish after 1945, but took other forms. At that time, numerous cooperatives were established in Poland, whose task was to create everyday objects and works of folk art, in line with the local tradition in terms of technology, iconography, ornaments, etc. In Podhale, among many produced works, a certain part was the so-called metalwork – belt buckles, shirt clips, purse fasteners, knives, etc., the shape of which was an inspiration for artists creating bracelets, brooches, pendants, etc. This assortment was supplemented with other items – made of sheet metal, bovine bone, galalite and wood, brooches, pendants, and key rings, which were primarily souvenirs brought from this very popular tourist region.
Ludowość utracona? Strategie instytucjonalizacji sztuki ludowej w Szkole Przemysłu Drzewnego w Zakopanem
Authors: Muszkowska Maria 
Published: December 2021

Abstrakt:
W jakim stopniu funkcjonujące dzisiaj wyobrażenie „góralszczyzny” odpowiada tradycyjnej twórczości Podhala sprzed prób jej instytucjonalizacji? Tekst stanowi analizę metod konstruowania stylów regionalnego i narodowego, jakie realizowano w programach zakopiańskiej Szkoły Przemysłu Drzewnego z lat 1879–1939. Ówczesna twórczość rzeźbiarska wykładowców i wychowanków placówki oraz prowadzona w jej zakresie edukacja ukazują różnorodność prób instytucjonalizacji oraz instrumentalizacji ludowości. W literaturze przedmiotu brakuje jednak wyczerpującej analizy tych procesów. Celem tekstu jest prześledzenie (nad)użyć folkloru, do jakich dochodziło w obrębie uczelni. Analizie zostały poddane programy edukacji realizowane przez dyrektorów: Franciszka Neužila, Edgara Kovátsa, Stanisława Barabasza, Karola Stryjeńskiego oraz Adama Dobrodzickiego. Genealogia przywołanych koncepcji kształcenia ujawnia pewną ambiwalencję: nauczające wytwórczości ludowej programy były w rzeczywistości formami artystycznej ingerencji w regionalną kulturę Podhala, tworzonymi w większości przez „obcych” i dla „obcych”. Całość rozważań została zrealizowana z perspektywy studiów postkolonialnych oraz historii społeczno-politycznej.
Summary:
To what extent does the present image of Polish “highland culture” reflect the traditional art and craftsmanship of Podhale from before its institutionalization? This study offers an analysis of methods of creation of regional and national style, conducted at the School of Wood Industry in Zakopane from 1879 to 1939. Art and craft of students and professors and the educational methods demonstrate various attempts of institutionalization and instrumentalization of folklore. Literature on the subject lacks a thorough analysis of those processes. The object of this study was to trace the (ab)uses of folklore that happened on account of the School. Analyzed were the teaching programmes carried out by headmasters: Franciszek Neužil, Edgar Kováts, Stanisław Barabasz, Karol Stryjeński, and Adam Dobrodzicki. Those methods of education reveal an ambivalence: while officially teaching local folklore and craft, they were in fact a form of artistic interference with the regional culture of Podhale, by “strangers” and for “strangers”. The text was based on postcolonial studies and socio-political history.
