Published: November 2021

Kokosanolide A (1), from the seeds of Lansium domesticum Corr. cv Kokossan, has been shown strong cytotoxic activities (IC50 = 8.62 μg/mL) against MCF-7 breast cancer cells. The aim of this work was to study the molecular interactions of kokosanolide A and kokosanolide C with the Estrogen Receptor α (ERα) using computer-aided drug design approaches. Molecular docking using Autodock Vina (open-source software PyRx 0.8) was employed to explore the modes of binding of kokosanolide A (1) and kokosanolide C (2) with ERα. Compounds 1 and 2 showed strong bond-free energy (-8.8 kcal/mol and -8.7 kcal/mol) to ERα. These two compounds have a molecular mechanism to inhibit ERα in breast cancer cells.

OBJECTIVE

To reduce care failures by 30% through implementation of standardized communication processes for postoperative handoff in NICU patients undergoing surgery over 12 months and sustained over 6 months.

METHODS

Nineteen Children’s Hospitals Neonatal Consortium centers collaborated in a quality improvement initiative to reduce postoperative care failures in a surgical neonatal setting by decreasing respiratory care failures and all other communication failures. Evidence-based clinical practice recommendations and a collaborative framework supported local teams’ implementation of standardized postoperative handoff communication. Process measures included compliance with center-defined handoff staff presence, use of center-defined handoff tool, and the proportion of handoffs with interruptions. Participant handoff satisfaction was the balancing measure. Baseline data were collected for 8 months, followed by a 12-month action phase and 7-month sustain phase.

RESULTS

On average, 181 postoperative handoffs per month were monitored across sites, and 320 respondents per month assessed the handoff process. Communication failures specific to respiratory care decreased by 73.2% (8.2% to 4.6% and with a second special cause signal to 2.2%). All other communication care failures decreased by 49.4% (17% to 8.6%). Eighty-four percent of participants reported high satisfaction. Compliance with use of the handoff tool and required staff attendance increased whereas interruptions decreased over the project time line.

CONCLUSIONS

Team engagement within a quality improvement framework had a positive impact on the perioperative handoff process for high-risk surgical neonates. We improved care as demonstrated by a decrease in postoperative care failures while maintaining high provider satisfaction.
National Trends of Adolescent Exposure to Tobacco Advertisements: 2012–2020
Authors: Li Xiao , Kaiser Nina , Borodovsky Jacob T. , Riordan Raven , Kasson Erin , Cao Chao , Cavazos-Rehg Patricia A.
Published: November 2021

BACKGROUND AND OBJECTIVES

The objective of the current study is to evaluate the temporal trends in the prevalence of cigarette and electronic cigarette (e-cigarette) advertisement exposure by venue and sociodemographic correlates among US adolescents from 2012 to 2020.

METHODS

We conducted a serial cross-sectional analysis of nationally representative samples of middle and high school youth from the 2012–2020 National Youth Tobacco Survey. Advertisement exposure was defined as self-report of seeing advertisements “sometimes,” “most of the time,” and “always.” The prevalence of cigarette (and other tobacco products) and e-cigarette advertisement exposure, including overall and at specific venues (Internet, press, screen, and retail stores), was estimated by survey year.

RESULTS

A total of 139 795 adolescents aged 11 to 19 years old were included in the analysis. The prevalence of exposure to combustible cigarette marketing remained high across all years (any venue ranging from 77.0% [2018] to 91.1% [2014]). An increasing trend for cigarette advertisement exposure was observed from 2017 to 2020 after a drop in 2015 (β2012–2015 = 2.8, P for trend < .001; β2017–2020 = .7, P for trend = .03), driven by retail store–based and Internet-based exposure. A similar increasing pattern in the estimated prevalence of e-cigarette marketing was observed (β2014–2016 = 4.6, P for trend < .001; β2017–2020 = 5.1, P for trend < .001).

CONCLUSIONS

Given the high estimated prevalence of cigarette and e-cigarette marketing exposure among US adolescents, further regulation efforts for both off-line and online tobacco marketing are needed to mitigate adolescent exposure to content regarding these products, reducing susceptibility to uptake.
Nonmedical Opioid Use After Short-term Therapeutic Exposure in Children: A Systematic Review
Authors: Ahrari Malema , Ali Samina , Hartling Lisa , Dong Kathryn , Drendel Amy L. , Klassen Terry P. , Schreiner Kurt , Dyson Michele P.
Published: November 2021

CONTEXT

Opioid-related harms continue to rise for children and youth. Analgesic prescribing decisions are challenging because the risk for future nonmedical opioid use or disorder is unclear.

OBJECTIVE

To synthesize research examining the association between short-term therapeutic opioid exposure and future nonmedical opioid use or opioid use disorder and associated risk factors.

DATA SOURCES

We searched 11 electronic databases.

STUDY SELECTION

Two reviewers screened studies. Studies were included if: they were published in English or French, participants had short-term (≤14 days) or an unknown duration of therapeutic exposure to opioids before 18 years, and reported opioid use disorder or misuse.

DATA EXTRACTION

Data were extracted, and methodologic quality was assessed by 2 reviewers. Data were summarized narratively.

RESULTS

We included 21 observational studies (49 944 602 participants). One study demonstrated that short-term therapeutic exposure may be associated with opioid abuse; 4 showed an association between medical and nonmedical opioid use without specifying duration of exposure. Other studies reported on prevalence or incidence of nonmedical use after medical exposure to opioids. Risk factors were contradictory and remain unclear.

LIMITATIONS

Most studies did not specify duration of exposure and were of low methodologic quality, and participants might not have been opioid naïve.

CONCLUSIONS

Some studies suggest an association between lifetime therapeutic opioid use and nonmedical opioid use. Given the lack of clear evidence regarding short-term therapeutic exposure, health care providers should carefully evaluate pain management options and educate patients and caregivers about safe, judicious, and appropriate use of opioids and potential signs of misuse.

Published: November 2021

Agriculture affects nature and natural resources, changes the environment, and causes environmental problems. But as an economic activity it is directly related to natural conditions and dependent on natural forces. And nature management leads to environmental consequences. Organic farming has a lesser impact on the environment and contributes to its protection.
The purpose of this study is to monitor the impact of organic farming on ecology and environmental protection. To achieve this goal the following tasks are solved: analyzing the state and development of organic farming in Bulgaria; studying the impact between organic farming and ecology; to substantiate the conclusions and recommendations of the study
The methods and approaches used to achieve the goal and solve the problems are analysis and synthesis, systematic, synergetic and structural approach, induction and deduction, statistical methods, expert evaluations.
The expectations of the study are to establish that there is a potential for the growth of organic farming which has an impact on environmental protection.
ATTITUDES TOWARDS INNOVATIONS: EVIDENCE FROM WINE INDUSTRY ENTERPRISES
Authors: Angelova M. , Pastarmadzhieva D.
Published: November 2021

The innovations take an essential role in the Bulgarian economic environment as well as in the national strategies for economic growth. For many companies, improving and increasing innovation and the ability to develop innovation is the most important factor for growth. The paper explores the innovation activity of the wine industry as a specific sector of the Bulgarian economy. The purpose of the current study is to identify the attitudes of the wine producers towards innovations and to discuss the innovation activity of their enterprises. The methods used include in-person verbal interviews, which were conducted with 15 participants as expert practitioners to test the ideas, build knowledge, and gain insightful context and nuance to the ideas. The results show that although some of the wine producers implement innovations they don’t realize it. The focus of their innovations is in the product, process, and technological innovations, because they try to reach a balance between quality and price. It looks like that the institutions are more like obstacle rather than support for such activity. Thus, we can conclude that to a high extent the wine producers in Bulgaria are implementing and willing to implement innovations. However, they are not well aware of the possible innovations, their potential for increasing competitiveness and therefore are focusing only on directly improving their product.

Published: November 2021

Energy of surface waves is almost dissipated as propagating from shallow water to muddy flat and in mangrove forest. The study aims to analyze energy spectral density by using Blackman-Tukey (BT) and Fast Fourier Transform (FFT) methods in order to analyze the wave energy in mangrove areas in Cu Lao Dung (Soc Trang province). BT method is easy to use especially in short time series. Selection of lag number m is very important to determine the energy amount and number of peaks. Whereas, FFT method helps us to analyze the shift of spectral energy as waves propagate into shallower water. The results show that wave energy is dissipated from shallow water to muddy flat and into mangrove forests. The spectral energy shifts from low frequency to higher frequency as propagating into mangrove forests. This can prove the non-linear characteristics of waves in mangrove forests and the complicated hydrodynamic processes in mangrove forests.
CFD investigation of interaction effect between hull and accommodation on wind drag of a container ship in head wind
Authors: Ngo Van He , Truong Van Thuan
Published: November 2021

In this paper, we present a research on applying a commercial Computational Fluid Dynamics (CFD) code to determine interaction effect between hull and accommodation on wind drag of a container ship. For the high superstructure and large windward area ships such as container, wind drag acting on hull accounts for a large amount of total resistance. To clearly find aerodynamic performance and interaction effects on wind drag of a container ship, a full scale 1,200 TEU container has been used as a reference model. From results of comparison in the two computed cases of hull with and without accommodation, the interaction effects between hull and accommodation on aerodynamic performance and wind drag have been investigated. The targets of the paper has proposed a new solution to improve aerodynamic performances and reduce wind drag acting on the ship by reducing interaction effects between hull and accommodation.
THE FACTORS CAUSING ENGLISH SPEAKING ANXIETY ON NON-ENGLISH MAJOR ACADEMICS WHILE USING ENGLISH AS A MEDIUM OF INSTRUCTION
Authors: Yildiz Mustafa
Published: November 2021

This qualitative study aims to reveal the factors causing English speaking anxiety on non-English major academics while using English as a medium of instruction. Eight non-English major academics with the experience of teaching in English participated in the present research. Semi-structured one-on-one interviews and e-mail interviews, which are qualitative data collection techniques, were used as data collection tools. Manual coding of qualitative data that requires in-depth reading of the transcripts and assigning codes and themes was used to interpret the data. The results reveal the situations that provoke speaking anxiety among the non-English major academics. They can be grouped under five main themes: academics’ English proficiency, academics’ self-evaluation, learner behaviors, learner inadequacies, and cultural differences. These five main themes can also be confined to individual factors, learner factors, and cultural factors. It can therefore be assumed that the factors causing English speaking anxiety on non-English major academics have to be considered within multidimensional aspects rather than simply originating from academics themselves
READER-TEXT CONNECTION: REPORTING THE ENGAGEMENT OF HIGH SCHOOL STUDENTS WITH CULTURALLY RELEVANT TEXTS
Authors: Tan Dannah Neriah L. , Mante-Estacio Ma. Joahna
Published: November 2021

Maintaining students’ engagement with reading texts that reflect their background knowledge has positive effect on their comprehension. Culturally relevant materials provide more equitable opportunities to students, in the sense that more of them can reap the benefits of being able to connect to the text (Christ & Sharma, 2018). This article aims to identify the characteristics of texts, particularly those categorized as culturally relevant, which make them appropriate for a specific group of students. Three data gathering methods were used: ratings of texts, reflective journals, and discussion points during Literature Circles. Results indicate that the students participating in the study consider that similar experiences, relatability of the story in terms of feelings and motivation conveyed, actions of the characters, and possibility of experiencing the same event are the main factors that made reading texts culturally relevant to them. These text characteristics can guide classroom teachers, materials developers, and curriculum designers in choosing materials and preparing lessons for specific groups of students, as these underscore the importance of text relatability in building and keeping the students’ reading interest and motivation.

Flexible Bayesian Nonlinear Model Configuration
Authors: Hubin Aliaksandr , Storvik Geir , Frommlet Florian
Published: November 2021

Regression models are used in a wide range of applications providing a powerful scientific tool for researchers from different fields. Linear, or simple parametric, models are often not sufficient to describe complex relationships between input variables and a response. Such relationships can be better described through  flexible approaches such as neural networks, but this results in less interpretable models and potential overfitting. Alternatively, specific parametric nonlinear functions can be used, but the specification of such functions is in general complicated. In this paper, we introduce a  flexible approach for the construction and selection of highly  flexible nonlinear parametric regression models. Nonlinear features are generated hierarchically, similarly to deep learning, but have additional  flexibility on the possible types of features to be considered. This  flexibility, combined with variable selection, allows us to find a small set of important features and thereby more interpretable models. Within the space of possible functions, a Bayesian approach, introducing priors for functions based on their complexity, is considered. A genetically modi ed mode jumping Markov chain Monte Carlo algorithm is adopted to perform Bayesian inference and estimate posterior probabilities for model averaging. In various applications, we illustrate how our approach is used to obtain meaningful nonlinear models. Additionally, we compare its predictive performance with several machine learning algorithms.
Graph Kernels: A Survey
Authors: Nikolentzos Giannis , Siglidis Giannis , Vazirgiannis Michalis
Published: November 2021

Graph kernels have attracted a lot of attention during the last decade, and have evolved into a rapidly developing branch of learning on structured data. During the past 20 years, the considerable research activity that occurred in the field resulted in the development of dozens of graph kernels, each focusing on specific structural properties of graphs. Graph kernels have proven successful in a wide range of domains, ranging from social networks to bioinformatics. The goal of this survey is to provide a unifying view of the literature on graph kernels. In particular, we present a comprehensive overview of a wide range of graph kernels. Furthermore, we perform an experimental evaluation of several of those kernels on publicly available datasets, and provide a comparative study. Finally, we discuss key applications of graph kernels, and outline some challenges that remain to be addressed.
PredictingVpand constrained modulus reduction curve based onVsand shear modulus reduction curve in accordance with poroelastic theory
Authors: Tsai Chi-Chin , Liu Hsing-Wen , Asimaki Domniki
Published: November 2021

The compression wave velocity (Vp) of sediments plays a key role in seismic wave amplification of vertical motion and is required in site response analysis. However, such information is usually lacking during field exploration (e.g. the surface wave method) because only shear wave velocity (Vs) is obtained. This aim of this study is to predict Vpbased on Vsempirically and theoretically, particularly focusing on saturated conditions. The empirical approach is to establish the Vpcorrelation dependency on Poisson's ratio and Vs, and the theoretical approach is based on poroelastic theory that accounts for the interaction between fluid and soil skeleton. The engineering geological database for the Taiwan strong motion instrumentation program and the Kiban Kyoshin network database in Japan are adopted to establish an empirical model and validate poroelastic theory. The validated poroelastic approach is used to develop a constrained modulus reduction curve dependency on the porosity, Vs, Poisson's ratio and degree of saturation with a shear modulus reduction curve. The proposed approach can be used to develop generic Vpprofiles and constrained modulus reduction curves for the site response to vertical motion given a site-specific Vsprofile.

Published: November 2021

Las explotaciones del sistema ganadero doble propósito están constituidas por animales mestizos en diferentes proporciones Bos taurus-Bos indicus; su principal característica es el ordeño con presencia del ternero. Otro aspecto para tener en cuenta es que, en la mayoría de las explotaciones no se cuenta con información y, si existe, no es analizada ni interpretada. El documento tiene como objetivo presentar información de la funcionalidad técnica y estructural del sistema doble propósito en Arauca. Los datos fueron recolectados durante el desarrollo de un proyecto de investigación; se realizó una descripción de las características generales del sistema, su estructuración, aspectos de manejo y alimentación, así como los indicadores productivos y reproductivos, expresados en producción de carne y leche de los grupos raciales. Este es el primer manuscrito que reporta información de tipo productiva de los grupos raciales existentes. Se concluye que el manejo del sistema ganadero doble propósito, aún tradicional, y su mejoramiento genético para aumentar la producción consiste en la introducción de “razas de moda”, por lo que se olvida el efecto de los factores medio ambientales. La falta de registros se asocia al desconocimiento de la productividad y de la estructura, así como la funcionalidad del sistema doble propósito.

Published: November 2021

The features of the rheological behavior of CFRC matrix systems are considered as highly concentrated dispersed systems. They are characterized by a dilatative, thixotropic and thixotropic-dilatant nature of the flow, depending on the composition, concentration, dispersion, and a number of other factors. The equation of the concentration dependence of the viscosity of suspensions (Pivinskii equation) is proposed. It is shown that the determining factor is the content of a kinetically free dispersion medium in them. The effect of the content of grain aggregate on the rheological properties of foundry systems is characterized. The significant effect of polydispersity of the particles of the solid phase and the temperature on the rheological properties of the HCBS with the dilatant nature of the flow is shown. The data on the effect of defloculation and stabilization of matrix systems on their rheological properties, which determine the reeterological properties of molding systems to obtain CFRC. Ill. 13.

Felekezetek a végvidéken. A román reformáció egyház- és eszmetörténeti tanulságai
Authors: Molnár Antal
Published: November 2021

Jelen ismertetés egy hosszú kutatómunka lezárásaként, eredetileg akadémiai doktori értekezésnek készült monográfiának a szokásosnál részletesebb, elsősorban a délkelet-európai egyháztörténeti kontextusra figyelő bemutatását tűzi ki célul. A könyv szerzője Nagy Levente, az ELTE Román Filológiai Tanszékének tanszékvezető egyetemi docense, a magyar irodalomés művelődéstörténet, illetve a magyar–román szellemi érintkezések történetének ismert és elismert kutatója. Munkásságának egyik fontos szelete az Erdélyi Fejedelemség román kultúrtörténetének sokat vizsgált, ugyanakkor ellentmondásosan megítélt és sok tekintetben enigmatikus jelensége, a román reformáció históriája, illetve annak egy új szempontú, úgynevezett kulturális transzferjelenségként történő értelmezése. A szerző a témáról az elmúlt években számos tanulmányt tett közzé, illetve egy önálló kötetet is publikált.2 Az itt ismertetett könyv ezeknek az eredményeknek a kibővített, több esetben újragondolt és monográfiává érlelt korpusza. A munka kiemelkedő erénye, hogy hosszú évtizedek hallgatása után mutat be a magyar olvasóközönség számára egy magyarországi, de nem magyar nyelvű vallási-kulturális jelenséget, amelynek Romániában megjelent, román nyelvű szakirodalma a magyar szakemberek túlnyomó többsége számára hozzáférhetetlen. Ugyanakkor a szintetizáló jelleg mellett a sokéves forráskutatás eredményei is beépülnek a monográfiába, tehát a szerző nemcsak összefoglalja a román reformáció történetét, hanem saját kutatásai alapján, a román tudományosság számára is releváns módon tovább építi az arról alkotott képet.
Traumatic Brain Injury in the Elderly is common but is not as Bad as we Think! Exercise, not rest, can ensure faster recovery from post-concussion syndromes “Autobiographical case report”
Authors: Suresh Kishanrao
Published: November 2021

Head injuries, medically known as Traumatic Brain Injuries (TBI) are a leading cause of seeking emergency medical care, hospitalization, long hospital stays, disabilities, rehabilitation services, case fatalities and socioeconomic losses in India. Head trauma is one of the common injuries in the old due to trivial falls, and its consequences need not be grievous always. As many of the elderly are on medication for hypertension, diabetes, and heart ailments and due to sudden rising from the bed, or even from the commode or Indian style of squatting plate develop giddiness and fall. Incidence of head injuries is rising all over the world but fortunately more than half of them is either mild or moderate amenable to management with good outcomes. They can sometimes be serious and fatal when left untreated. The epidemiology of TBI is still an enigma in the medical world due to inconsistency in the definition and classification and discrepancies in data collection. Glasgow Coma Scale (GCS) is a well-accepted tool to assess the seriousness at the first visit to stratify, monitor the prognosis, and recovery of brain functions in patients with traumatic brain injury. Seniors over the age of 60 years with head injury are generally considered to have a poor outcome. However, a recent large multicentric China epidemiologic study of minor head injury patients (GCS 13–15) reported over 90 % survival, few with minor consequences. Another large-scale retrospective study at a level II trauma centre in Florida from 2005 to 2008, too indicated that the outcome of elderly over 65 years old had a survival rate of over 80 %. I report my own autobiographical case of a closed head injury, with good outcome due to timely care and early initiation of aerobic exercise (waking & tread meal) for recovery from concussion injury due to fall in washroom, with no major post-concussive symptoms.

Single cell sequencing methods facilitate the study of tissues at high resolution, revealing rare cell types with varying transcriptomes or genomes, but so far have been lacking the capacity to investigate cell-cell interactions. Here, we introduce CIM-seq, an unsupervised and high-throughput method to analyze direct physical cell-cell interactions between every cell type in a given tissue. CIM-seq is based on RNA sequencing of incompletely dissociated cells, followed by computational deconvolution of these into their constituent cell types using machine learning. CIM-seq is broadly applicable to studies that aim to simultaneously investigate the constituent cell types and the global interaction profile in a specific tissue.

CIM-seq is based on RNA sequencing of incompletely dissociated cells, followed by computational deconvolution of these into their constituent cell types using machine learning. CIM-seq is broadly applicable to studies that aim to simultaneously investigate the constituent cell types and the global interaction profile in a specific tissue.

Amaç:Çalışmamızda Ani idiopatik sensorinöral işitme kaybı (AİK) olanlarda belirlediğimiz prognostik faktörlerin ve kombine tedavilerin, intratimpanik steroid enjeksiyonu sonrası işitmedeki düzelme üzerine etkilerini araştırdık.
Gereç ve yöntemler:2018-2019 yılları arasında Kahramanmaraş Sütçü İmam Üniversitesi Kulak Burun Boğaz kliniğinde AİK sebebiyle ayaktan veya yatarak tedavi alan, başka sağlık kuruluşunda tedavi almamış ve işitme kaybının başlangıcı ile tedaviye başlama arasında geçen süre 3 haftadan kısa olan 30 hasta retrospektif olarak incelendi.
Bulgular:Çalışmaya 17 kadın 13 erkek olmak üzere 30 hasta dahil edildi. Hastaların yaş ortalaması 46 idi.Hastaların iyileşme düzeyleri Siegel kriterlerine göre değerlendirildi ve %30’unda (n=9) tip 1 (tam düzelme), %10’unda (n=3) tip 2 (belirgin düzelme), %10’unda (n=3) tip 3 (hafif düzelme) ve %50’sinde (n=15) tip 4 (düzelme yok) olarak kaydedildi. Çalışmamıza dahil edilen komorbid faktörler arasında, diğer faktörlerin iyileşme üzerine anlamlı etkisi yoktu (p>0,05). Buna ek olarak intratimpanik steroid enjeksiyonu ile kombine olarak verilen tedaviler arasında da işitme kazanımları açısından istatistiksel olarak anlamlı bir fark bulunmadı. Hasta grubumuzdaki öykü süreleri bir gün ile yirmibir gün arasında değişmekteydi ve çalışmamızda şikayet ile tedaviye başlama arasında geçen süre beş günden kısa olanlarda iyileşme anlamlı bulundu (p<0,05).
Sonuç: Ani işitme kaybı; acil tanı konulup acil tedavi edilmesi gereken bir durumdur. Tedavi edilmediğinde kalıcı işitme kayıplarına, bireyin psikolojik, bilişsel, sosyal gelişimi üzerine olumsuz etkilere sebep olabilir. Çalışmamızda yalnızca intratimpaniksteroid tedavisi ve kombine tedavilerin birbirine üstünlük göstermediği bulundu.

Objective. To explore women's experiences of violence and their opinion on routine screening for domestic violence by nursing professionals in mental health care settings.

Methods. This qualitative narrative research design was carried out among 20 asymptomatic women with mental illness at a tertiary care centre in Bangalore, India.

Results. Narrative content analysis was performed, and five dominant themes have emerged: 1. Understanding the nature and signs of violence (subtheme: Meaning of violence), 2. Abusive experiences of women with mental illness (subthemes: Physical violence, psychological violence, social violence, sexual violence and financial violence), 3. Experiences on disclosure of violence (subthemes: Identification of violence by nursing professionals, Experiences of disclosure of violence), 4. Barriers for disclosure of abuse(subthemes: Fear of consequences, the hectic schedule of nursing staff, helplessness and hopelessness, perceived poor family support). 5.Routine screening for violence by nursing professionals (subthemes: reasons for routine inquiry of violence, nature of inquiry by the nursing professionals).

Conclusion. Women with mental illness were undergoing more than one form of violence, and most of the participants supported routine screening by nursing professionals. Nurses play an essential role in identifying and supporting abused women in mental health care settings.

Objective. To identify the physiological changes in older adults’ vision during the aging process.

Methods. An exploratory, descriptive study with a qualitative approach was conducted with 20 older adults and six healthcare providers who worked with older adults in João Pessoa, Paraíba (Brazil). The Focus Group Technique was used for data collection, with the collected information subsequently being submitted to Inductive Thematic Analysis using textual analysis software.

Results. The physiological changes related to vision were described by both the older adults and healthcare providers using the following words: vision, difficulty; see; cataract; glasses; surgery; more; age; eye; and no. These terms represent declines in vision resulting from advancing age which significantly modify the daily lives of older adults and their families.

Conclusion. The perception of the older adults and the healthcare providers who care for them regarding the physiological changes in vision throughout the aging process shows that the loss of visual acuity significantly affects the daily life of older adults and their families.

Objective. To analyze the literature available on the psychometric properties of the instruments to measure knowledge, attitudes, and practices of the nursing care process.

Methods. This was a narrative-type review conducted by following the recommendations of the PRISMA declaration. The search strategy was executed in two stages; through the search in databases by two reviewers and – thereafter – three reviewers identified independently the studies and evaluated the methodological quality of the measurement instruments by using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) property checklist boxes.

Results. Of 71 studies identified for the full-text review, only seven complied with the inclusion criteria that represent four instruments (Q-DIO, D-CATCH, NP-CDSS, PNP). It was found that the instruments continue in their validation and appropriation processes to reality in health services.

Conclusion. In spite of the evident evolution of the instruments to evaluate the implementation of the nursing care process, the need is still valid for an instrument that measures aspects of knowledge, attitudes, and practices in every stage of the process.
The League of Matteo Salvini: Fostering and Exporting a Modern Mass-Party Grounded on “Phygital” Activism
Authors: Zulianello Mattia
Published: November 2021

The Lega Nord (LN) has undergone a profound process of transformation since 2013, by replacing its historical regionalist populism with a new state-wide populist radical right outlook. However, very little is known about how such transformation impacted its organizational model, particularly the mass-party features that characterized it under its founding leader, Umberto Bossi. This article explores the organizational evolution of the party under Matteo Salvini by means of a qualitative in-depth analysis of 41 semi-structured interviews with representatives of the LN from four regions (Calabria, Emilia-Romagna, Lombardy, and Veneto) and primary documents. It underlines that the LN was turned into a disempowered and politically inactive “bad company,” charged with the task of paying the debts of the old party, while its structure, resources, and personnel were poured into a new state-wide organization called Lega per Salvini Premier (LSP). The LSP has not simply maintained the key features of the mass-party in the LN’s historical strongholds, but also pioneered a modern form of this organizational model grounded on the continuous interaction between digital and physical activism, i.e., “phygital activism,” which boosts the party’s ability to reach out to the electorate by delivering the image that the League is constantly on the ground. The LSP has sought to export this modern interpretation of the mass-party in the South; however, in that area its organizational development remains at an embryonic stage, and the party’s nationalization strategy has so far produced a “quasi-colonial” structure dominated by, and dependent on, the Northern elite.

The intricacies and explanatory factors underlying the demarcation of indigenous lands are still little known. In this sense, this article aims to list the main explanatory variables of the demarcation phenomenon based on a wide review of the available literature on the topic of demarcation of indigenous lands in Brazil. We concluded that 1. such demarcation processes are multifactorial and complex; 2. mobilization of indigenous peoples and judicialization of demarcation processes are key to understand their chances of completion and the time taken to do so; and 3. when compared to procedural, economic, and contextual factors, political factors have a greater weight in explaining the studied phenomena.

Background: Dipeptidyl peptidase (DPP)-4 inhibitors, anti-diabetic agents, are expected to be effective for treatment of non-alcoholic fatty liver disease (NAFLD). Several studies have shown that some DPP-4 inhibitors alleviate hepatic steatosis or steatohepatitis in type 2 diabetic mice or rats. Teneligliptin is DPP4 inhibitor whose efficacy to control blood sugar is well established but its effect on liver is not studied well. In present study we investigated effect of teneligliptin, a DPP-4 inhibitor on patients of type 2 diabetes with non-alcoholic steatohepatitis (NASH). Methods: This was a randomized, double-blind study in which 64 patients between ages of 18 to 80 years were selected for study. Participants were identified as type 2 diabetes with biopsy confirmed NASH. We excluded the patients with glucocorticoid use, hepatitis B or C, and other diseases that might affect liver function. Results: The mean HbA1c change after 48 weeks of therapy in group A was-1.06 % and in group B was-0.77% and this was statistically insignificant (p>0.06). The mean AST change after 48 weeks of therapy in group A was-45.4% and in group B was-33.3% and this was statistically significant (p<0.001). The mean ALT change after 48 weeks of therapy in group A was-41.6% and in group B was-22.7% and this was statistically significant (p<0.001). The change in liver fat content (LFC) after 48 weeks of therapy in group A was-15.4% and group B was-7.14% and this was also statistically significant (p<0.001).Conclusions: Result of our study revealed that teneligliptin significantly reduce serum transaminases in patients of NASH with type 2 DM. Teneligliptin significantly reduce LFC and delay progression of NASH independent of diabetes control in type 2 diabetes mellitus (DM) patients. These data show significant antisteatotic and anti-inflammatory effect of teneligliptin in type 2 diabetes patients.
