Purpose:
To report the anatomical and functional outcomes of retinotomy and/or retinectomy for the management of rhegmatogenous retinal detachment (RRD) complicated by advanced proliferative vitreoretinopathy (PVR).

Methods:
In this retrospective study, the charts of patients who underwent pars plana vitrectomy with retinotomy and/or retinectomy for the management of RRD complicated by PVR were reviewed. Primary outcome measures were final best-corrected visual acuity (BCVA) and anatomical reattachment rate.

Results:
Sixty-one eyes of 61 patients with a mean age of 48.56 ± 15.92 were studied. The mean follow-up time was 21.38 ± 23.08 months. The mean angle of the retinotomy was 171.31° ± 79.15°. Thirty-two (52.5%) of them needed extensive (≥180°) retinotomy. In addition, simultaneous retinectomy was performed in 36.2% of the cases. The BCVA was 2.18 ± 0.63 and 1.85 ± 0.71 logMAR before the surgery and at the last visit, respectively (P = 0.001). The initial anatomical success was achieved in 45 eyes (73.8%) after retinotomy surgery. Sixteen eyes (26.2%) had recurrent RD and needed reoperation, which was performed 5.60 ± 4.01 months after the initial retinotomy surgery. At the last examination, the retina was attached in all patients.

Conclusion:
Retinotomy with/without retinectomy is an effective procedure in the majority of patients with RRD associated with advanced PVR; however, additional surgeries are needed in a significant number of eyes to achieve final anatomical success.

Purpose:
To study the role of statin therapy on diabetic retinopathy (DR) progression.

Methods:
This retrospective study was carried out at a tertiary care hospital in southern India. Data were collected from the medical records of patients admitted from January 2013 to December 2018. Out of 1673 patients of DR enrolled in the study, 171 met the inclusion criteria. Patients' demographic data, drug history, clinical characteristics, and laboratory investigations were recorded as per the pro forma. The patients were divided into statin users and nonusers. The results were analyzed to compare the DR progression between the two groups.

Results:
DR progressed in 67% of nonstatin users and 37% of statin users (P < 0.001). The use of statins decreased the risk of DR progression (P < 0.001). Center-involving macular edema was seen in 8 of 79 statin users (10%) and 16 of 92 statin nonusers (16%) based on optical coherence tomography findings during the follow-up period (P = 0.17).

Conclusion:
In patients with type 2 diabetes, lipid-lowering therapy with statins has the potential to retard DR progression.

Abstract

Objectives:
Trauma is one of the leading causes of death and its incidence increases annually. The “weekend effect” and “holiday season effect” on traumatic injury mortality remain controversial, whereby traumatic injury patients admitted during weekends and/or holiday season have a higher risk of in-hospital death. The present study is aimed to explore the association between “weekend effect” and “holiday season effect” and mortality in traumatic injury population.

Materials and Methods:
This retrospective descriptive study included patients from the Taipei Tzu Chi Hospital Trauma Database between January 2009 and June 2019. The exclusion criterion was age of < 20 years. The primary outcome was the in-hospital mortality rate. The secondary outcomes included intensive care unit (ICU) admission, ICU re-admission, length of stay (LOS) in the ICU, ICU admission duration ≥ 14 days, total hospital LOS, total hospital LOS ≥ 14 days, need for surgery, and re-operation rate.

Results:
In this study, 11,946 patients were included in the analysis, and 8143 (68.2%) patients were admitted on weekdays, 3050 (25.5%) on weekends, and 753 (6.3%) on holidays. Multivariable logistic regression revealed that the admission day was not associated with an increased risk of in-hospital mortality. In other clinical outcome analyses, we found no significant increase in the risk of in-hospital mortality, ICU admission, ICU LOS ≥ 14 days, or total LOS ≥ 14 days in the weekend and holiday season groups. The subgroup analysis showed that the association between holiday season admission and in-hospital mortality was noted only in the elderly and shock condition populations. The holiday season duration did not differ in terms of in-hospital mortality. Longer holiday season duration was also not associated with an increased risk of in-hospital mortality, ICU LOS ≥14 days, and total LOS ≥14 days.

Conclusion:
In this study, we did not find any evidence that weekend and holiday season admissions in the traumatic injury population were associated with an increased risk of mortality. In other clinical outcome analyses, there was no significant increase in the risk of in-hospital mortality, ICU admission, ICU LOS ≥ 14 days, or total LOS ≥ 14 days in the weekend and holiday season groups.
Network Topology Classification in SDN Ecosystem using Machine Learning
Authors: AHIRE KAVITA , Yadav Jyoti 
Published: July 2022

To meet the increasing network demands of enterprise environments and data centers, traditional network architectures have been replaced by software-enabled hardware devices for developing agile, dynamic, and programmable networks. Software Defined Networking (SDN) is a new paradigm shift that abstracts network design and infrastructure in the software and then implements it by using software across hardware devices. SDN is used to build and manage the network in a customized way. SDN architecture offers network virtualization, network programmability, and flexibility by decoupling control and data planes which further enriches the network performance. As such, the SDN controller is a tactical control point in SDN. An SDN normally allows data flow control to the switches and/or routers and the rationale of the application's logic for deploying intelligent networks. SDN with Machine Learning (ML) and Artificial Intelligence (AI) techniques build network models, which essentially can take decisions based on self-learning and self-management capabilities. Accurate classification of topology is of prime importance to satisfy future network prerequisites like unpredictable traffic patterns, dynamic scaling, flexibility, and centralized control. The controller needs to have exact information about the topology of the network in order to configure and manage the network. Subsequently, topology classification is an important component of any Software Defined Network architecture. This paper presents the classification of topologies using different supervised ML algorithms. The accuracy obtained from Support Vector Machine (SVM) and Classification and Regression (CART) is 95% and 90% respectively. The experimental results show that according to the k Cross-Fold validation technique, SVM algorithm has been found to be the most accurate amongst the other ML algorithms with a mean accuracy value of 85%.
NEGRINHA E A MENINA BONITA DO LAÇO DE FITA: Uma análise acerca da identidade étnico-racial na Literatura Brasileira
Authors: Revista Alembra  
Published: July 2022

O presente artigo apresenta uma análise acerca da identidade étnico-racial na literatura brasileira á luz de duas obras literárias, sendo a Negrinha de Monteiro Lobato e a Menina Bonita do laço de fita de Ana Maria Machado. Mesmo sendo considerados contos na categoria infantil e infanto -juvenil são obras de grandes reflexões para todas as idades, no permeio de suas escritas e ilustrações é possível interpretar e refletir vários viés que as obras em questão nos transmitem. Buscamos fundamentar-se na possibilidade que a literatura tem para desnudar as mazelas sociais e consequentemente a contribuição para a formação do homem, tais como a ilustração narrativa sobre a escravidão e a literatura afro-brasileira e sua respectiva importância no cenário brasileiro. Expor uma analise comparativa nas obras apresentadas tem como intenção demostrar a representação do negro, e suas características e a posição social nos quais são relatados em épocas distintas e em abordagens diferentes.

Published: July 2022

Physical activity during pregnancy is crucial not only for a woman's physical health but also for her emotional health and the outcome of pregnancy and childbirth. Providing sufficient and timely information to women about the importance of physical activity during pregnancy would encourage them to exercise.
Aim of the study – to analyse pregnant women's awareness of the benefits of physical activity during pregnancy.
Methods. Quantitative study, online questionnaire survey conducted in March 2022. The study involved 164 pregnant women with a mean age of 30.43±4.52 years. Statistical software package SPSS 21.0 for Windows was used for data analysis.
Results. 79% of the participants were pregnant for the first time and 83% of the women were 33-40 weeks pregnant at the time of the survey. The results showed a significant decrease in women's physical activity during pregnancy compared to the pre-pregnancy period, with 68.9% being physically active before pregnancy and 47.0% during pregnancy. In terms of changes in physical activity, it was found that, of those who were physically active before pregnancy, more than a quarter of the women had stopped physical activity during pregnancy. When analysing the body parts affected by pain and comparing the assessment of complaints during pregnancy according to physical activity during pregnancy, it was found that posterior pelvic pain and fatigue were statistically significantly more common in the physically inactive participants than in the physically active ones. Physically active women ranked walking, exercise, swimming, yoga as the most frequent physical activities during pregnancy and rated their health higher than physically inactive women. The study found that sources of information on the benefits of physical activity during pregnancy include: the internet, scientific articles, antenatal education and medical advice.
Conclusions. Women's awareness of the benefits of physical activity during pregnancy is low.
POR UMA ARQUEOLOGIA DOS ENVELHECIDOS: Aspectos Teóricos do Envelhecimento Humano
Authors: Mastrorosa Raquel Roldan 
Published: July 2022

Este artigo apresenta uma análise da relação das instâncias sociais, históricas, culturais e discursivas sobre os individuos envelhecidos com a produção do conhecimento arqueológico. A amplitude de interações teóricas interdisciplinares, precipuamente, a das ciências humanas, reflete novos questionamentos e possibilidades de pesquisa e interpretação da temática do envelhecimento humano na arqueologia. Trata-se de um constructo dotado de subjetividades e individualidades, não possuindo assim um caráter único, estático e universal. Verifica-se a necessidade da interação entre as abordagens osteoarqueológicas tácitas e as da teoria arqueológica interpretativa da cultura material, atualmente hegemônica, para o aprimoramento da reflexão sobre o corpo envelhecido nas diversas populações do passado e das inferências culturais e sociais sobre as mesmas.TOWARDS THE ARCHAEOLOGY OF OLD AGE: Theoretical Aspects of Human AgingABSTRACTThis article shows an analysis of the relationship between social, historical, cultural and discursive instances about aged individuals with the production of archaeological knowledge. The breadth of interdisciplinary theoretical interactions, especially that of the human sciences, reflects new questions and possibilities for research and interpretation of the theme of human aging in archaeology. It is a construct endowed with subjectivities and individualities, thus not having a unique, static and universal character. There is a need for interaction between tacit osteo-archaeological approaches and those of the interpretive archaeological theory of material culture, currently hegemonic, to improve the reflection on the aging body in the various populations of the past and the cultural and social inferences about them.Keywords: Archaeology of Old Age; Human Aging; Archaeological Theory; Osteoarchaeology; Archaeology of Body

Challenges in Measuring the Internet for the Public Interest
Authors: claffy kc , Clark David 
Published: July 2022

ABSTRACT
The goal of this article is to offer framing for conversations about the role of measurement in informing public policy about the Internet. We review different stakeholders’ approaches to measurements and associated challenges, including the activities of U.S. government agencies. We show how taxonomies of existing harms can facilitate the search for clarity along the fraught path from identifying to measuring harms. Looking forward, we identify barriers to advancing our empirical grounding of Internet infrastructure to inform policy, societal challenges that create pressure to overcome these barriers, and steps that could facilitate measurement to support policymaking.

On equality and justice in socio-economic relations
Authors: Саудаханов Марат Вильданович 
Published: July 2022

В статье затронута проблематика категорий равенства и справедливости в социально-экономических отношениях. В работе с помощью сравнительно-правового и исторического метода показана динамика развития феномена социальной справедливости и показаны факторы, повлиявшие на понимание категории равенства возможностей. В статье также затронута проблема имплементации идеи партнерства государства и личности в Российской Федерации. Неравномерное распределение доходов как практическая сторона социально-экономических отношений само по себе не всегда выступает следствием отсутствия социальной справедливости или результатом неэффективной государственной политики в сфере обеспечения своих обязательств. Автор приходит к выводу о том, что следует различать неравенство результатов и неравенство возможностей. То есть в случае, если имеет место обеспечение равными стартовыми возможностями всех граждан, равенства в обществе в плане потребления может и не быть. В этом случае можно также выделить то обстоятельство, что равенство как феномен может быть и положительным, и отрицательным. В этой связи справедливое неравенство - это достаточно привычная ситуация для демократического общества и нормальных социально-экономических отношений.
The article touches upon the problems of the categories of equality and justice in socio-economic relations. Using the comparative legal and historical method, the paper shows the dynamics of the development of the phenomenon of social justice and shows the factors that influenced the understanding of the category of equality of opportunities. The article also touches upon the problems of implementing the idea of partnership between the state and the individual in the Russian Federation. The uneven distribution of income as a practical aspect of socio-economic relations in itself is not always the result of a lack of social justice or the result of an ineffective state policy in the field of ensuring its obligations. The author concludes that it is necessary to distinguish between inequality of results and inequality of opportunities. That is, if there is a provision of equal starting opportunities for all citizens, there may not be equality in society in terms of consumption. In this case, we can also highlight the fact that equality, as a phenomenon, can be both positive and negative. In this regard, fair inequality is a familiar situation for a democratic society and normal socio-economic relations.
