Published: September 2021

OBJECTIVES: This study aimed to validate a simple risk assessment tool for estimating the advanced colorectal neoplasia (ACN) risk at colonoscopy screenings and potential factors relevant for implementing this tool in the Korean population.METHODS: Our study analyzed data from the Cancer Screenee Cohort Study conducted by the National Cancer Center in Korea. The risk level was assessed using the Asia Pacific Colorectal Screening (APCS) score developed by the Asia-Pacific Working Group on Colorectal Cancer. Logistic regression models were used to examine the associations between colorectal-related outcomes and the risk level by APCS score. The discriminatory performance of the APCS score for various colorectal-related outcomes was assessed using C-statistics.RESULTS: In 12,520 individuals, 317 ACN cases and 4,528 adenoma cases were found. The APCS tool successfully classified the study population into different risk groups, and significant differences in the ACN rate and other outcomes were observed. The APCS score demonstrated acceptable discrimination capability with area under the curve values ranging from 0.62 to 0.65 for various outcomes. The results of the multivariate logistic regression model revealed that the high-risk group had a 3.1-fold higher risk of ACN (95% confidence interval, 2.08 to 4.67) than the average-risk group. Body mass index (BMI) was identified as a significant predictor of ACN in both multivariate and subgroup analyses.CONCLUSIONS: Our study highlighted significant differences in colorectal-related screening outcomes by colorectal risk level measured using the APCS score, and BMI could be used to improve the discriminatory capability of the APCS score.

OBJECTIVES: Starting in March 2020, movement control measures were instituted across several phases in Malaysia to break the chain of transmission of coronavirus disease 2019 (COVID-19). In this study, we developed a susceptible-exposed-infected-recovered (SEIR) model to examine the effects of the various phases of movement control measures on disease transmissibility and the trend of cases during the third wave of the COVID-19 pandemic in Malaysia.METHODS: Three SEIR models were developed using the R programming software ODIN interface based on COVID-19 case data from September 1, 2020, to March 29, 2021. The models were validated and subsequently used to provide forecasts of daily cases from October 14, 2020, to March 29, 2021, based on 3 phases of movement control measures.RESULTS: We found that the reproduction rate (R-value) of COVID-19 decreased by 59.1% from an initial high of 2.2 during the nationwide Recovery Movement Control Order (RMCO) to 0.9 during the Movement Control Order (MCO) and Conditional MCO (CMCO) phases. In addition, the observed cumulative and daily highest numbers of cases were much lower than the forecasted cumulative and daily highest numbers of cases (by 64.4-98.9% and 68.8-99.8%, respectively).CONCLUSIONS: The movement control measures progressively reduced the R-value during the COVID-19 pandemic. In addition, more stringent movement control measures such as the MCO and CMCO were effective for further lowering the R-value and case numbers during the third wave of the COVID-19 pandemic in Malaysia due to their higher stringency than the nationwide RMCO.

Published: September 2021

Комплексы подслов были определены А. Кнутсоном и Э. Миллером в 2004 г. для описания грeбнеровских вырождений матричных многообразий Шуберта. Комплексы подслов специального типа называются комплексами rc-графов. Гиперграни такого комплекса индексируются диаграммами, называемыми rc-графами, или, что то же самое, мономами в соответствующем многочлене Шуберта. В 2017 г. C. Ассаф и Д. Сирлз определили базис, состоящий из слайд-многочленов, являющихся обобщением симметрических функций Стенли. Существует комбинаторное правило, позволяющее раскладывать многочлены Шуберта по этому базису. Мы описываем разложение комплексов подслов на страты, называемые слайд-комплексами, и показываем, что слайд-комплексы гомеоморфны дискам или сферам. В комплексах rc-графов эти страты соответствуют слайд-многочленам.

Exploring the Interaction between E484K and N501Y Substitutions of SARS-CoV-2 in Shaping the Transmission Advantage of COVID-19 in Brazil: A Modeling Study
Authors: Zhao Shi , Ran Jinjun , Han Lefei
Published: September 2021

The COVID-19 pandemic poses serious threats to global health, and the emerging mutation in SARS-CoV-2 genomes is one of the major challenges of disease control. Considering the growth of epidemic curve and the circulating SARS-CoV-2 variants in Brazil, the role of locally prevalent E484K and N501Y substitutions in contributing to the epidemiological outcomes is of public health interest for investigation. We developed a likelihood-based statistical framework to reconstruct reproduction numbers, estimate transmission advantage associated with different SARS-CoV-2 variants regarding the marking (identifying) 484K and 501Y substitutions (including Alpha, Zeta, and Gamma variants) in Brazil, and explored the interactive effects of genetic activities on transmission advantage marked by these two mutations. We found a significant transmission advantage associated with the 484K/501Y variants (including P.1 or Gamma variants), which increased the infectivity significantly by 23%. In contrast and by comparison to Gamma variants, E484K or N501Y (including Alpha or Zeta variants) substitution alone appeared less likely to secure a concrete transmission advantage in Brazil. Our finding indicates that the combined impact of genetic activities on transmission advantage marked by 484K/501Y outperforms their independent contributions in Brazil, which implies an interactive effect in shaping the increase in the infectivity of COVID-19. Future studies are needed to investigate the mechanisms of how E484K and N501Y mutations and the complex genetic mutation activities marked by them in SARS-CoV-2 affect the transmissibility of COVID-19.

It is essential to examine the longevity of the defensive immune response engendered by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. We examined the SARS-CoV-2-specific antibody responses and ex vivo memory B-cell subsets in seven groups of individuals with COVID-19 classified based on days since reverse-transcription polymerase chain reaction confirmation of SARS-CoV-2 infection. Our data showed that the levels of IgG and neutralizing antibodies started increasing from days 15 to 30 to days 61 to 90, and plateaued thereafter. The frequencies of naive B cells and atypical memory B cells decreased from days 15 to 30 to days 61 to 90, and plateaued thereafter. In contrast, the frequencies of immature B cells, classical memory B cells, activated memory B cells, and plasma cells increased from days 15 to 30 to days 61 to 90, and plateaued thereafter. Patients with severe COVID-19 exhibited increased frequencies of naive cells, atypical memory B cells, and activated memory B cells, and lower frequencies of immature B cells, central memory B cells, and plasma cells when compared with patients with mild COVID-19. Therefore, our data suggest modifications in memory B-cell subset frequencies and persistence of humoral immunity in convalescent individuals with COVID-19.
Searching for new fiscal rules in the euro area: a new proposal
Authors: Priewe Jan
Published: September 2021

While the European Union (EU) fiscal rules are suspended in the years 2020–2022, new rules are in the making and might be activated in 2023. If the old rules were used again, massive austerity would be required in the face of the strongly elevated level of public debt and the gap to the 60 per cent debt cap in the EU Treaty. A new proposal is suggested in this article which requires only small changes in the Treaty and/or the Fiscal Compact, but a strong overhaul in secondary law, that is, the Stability and Growth Pact. The key ideas are to use net interest payments, as a share of GDP, as the new metric for defining debt sustainability rather than gross public debt. This would allow the adjustment of the rules to changing monetary environments, especially interest-rate levels, and changing differentials between interest rates and growth rates. This way, much more fiscal space would be generated both for higher-debt and lower-debt member states and the entire euro area.
Textile wastewater treatment via membrane distillation
Authors: Sushvanth Reddy Appanu , Kalla Sarita , Murthy Z.V.P.
Published: September 2021

Due to the skyrocketed population growth and to meet clean water requirements, it is mandatory to develop techniques for proper conversion of wastewater and seawater into clean water. Textile industries generate a massive amount of wastewater. Processing of wastewater obtained from textile wastewater is more significant because of the pollutants present in the wastewater. Conventional separation processes like physical treatment, chemical treatment, and biological treatment are not pertinent in the current situation because of their lower separation efficiencies. Non-conventional separation processes are playing critical roles in ensuring the highest separation possible till date. Of these, membrane distillation (MD), which works based on trans-membrane vapor pressure difference, gives nearly 100% rejection. Thus, the present review highlights the latest work related to the separation of wastewater from the textile industries. This review also studies the limitations in terms of membrane fouling in the field of MD. Lastly, future work regarding membrane modification, MD integration, and MD commercialization are discussed. It is believed that these integrated membrane-driven separation processes will be rendered into relevant innovations in this field.

Published: September 2021

In the practical application of water treatment, the Fenton reaction usually works at a lower pH. To overcome the above shortcomings, a Fenton-like reaction system with copper sulfate as a catalyst was proposed. In this paper, quinoline was used as the target pollutant and the effects of catalyst dosage, H2O2 dosage, reaction temperature, and initial concentration of quinoline and pH on the removal effect were investigated, and the evolution in pH and hydroxyl radical concentration during reaction, as well as the possible catalytic mechanism and degradation pathway were clarified. The results show that under a catalyst dosage of 0.4 g･L-1, a H2O2 dosage of 196 mmol･L-1, a quinoline concentration of 100 mg･L-1 and a temperature of 75°C, the removal of quinoline and total organic carbon (TOC) reaches 99.5% and 87.2% in 65 min, respectively. Furthermore, the copper sulfate-driven homogeneous Fenton system exhibits a superior adaptability to pH in the range of 3.8 to 8.8. In the degradation of quinoline, ·OH radicals may attack the nitrogen ring and the benzene ring in sequence. The work provides a technical support for the treatment of organic wastewater, and shows promising in practical applications.
An Analysis of the History, Sociology, Theology and Future of the New Wine Movement
Authors:   , Goodwin Bruce
Published: September 2021

For tens of thousands of Christians in the United Kingdom, the New Wine Conference held in Somerset is a high point of their year. It has become an annual event to reinvigorate their spiritual lives. The wider New Wine Movement seeks to see ‘churches strengthened and renewed and demonstrate the good news of the Kingdom of God to all’. Despite the fact that it is now over twenty-five years old, up till now, no thorough scrutiny of the New Wine movement has yet been done. This dissertation is an attempt to redress this omission by undertaking a critical assessment of the history, sociology, theology and future of the movement. It is an inter-disciplinary analysis that crosses both historical and theological boundaries as well as sociological ones. Chapter one covers the birth of the movement, as well as the significant historical developments and challenges it has faced. Chapter two views the movement from a sociological perspective and makes comparisons with similar religious movements. Chapter three looks at its main theological distinctives and undertakes a close examination of three of its so-called values. No work of this nature would be complete without an assessment of the possible future for this movement, how it has changed and whether it will continue for many more years. This is the content of chapter four and chapter five summarises and concludes the thesis. The work is based on my own participant observation and interviews conducted with those familiar with New Wine and these are included as an appendix.

Psychology in the function of the well-being of the individual and society - BOOK OF ABSTRACTS
Authors: Autora Grupa
Published: September 2021

As the guidelines of human attitudes and behavior, the values are extremely important for individuals and for the society. All major societal flaws (violence, war, aggression, criminal, delinquency, lawlessness, corruption, ecological devastation, terrorism, totalitarianism, exploitation, misery, poverty, hunger, starvation, ignorance, fanaticism and others) are result of behavior that is as odd with basic human values. Thus, a value-congruent behavior is a necessary condition for stable and successful society and the strengthening of value-aligned behavior is a planetary task. Psychological research convincingly demonstrated that the values represent and occupy a great field of attitudes and beliefs, one of the three great domains of the psychological trilogy (personality; attitudes, beliefs and values; cognitive abilities). In psychology, we need a clear and elaborated theoretical explanation of values. A comprehensive theoretical model of values (CTV) was therefore developed in last decades. It comprises all important aspects of the values: the structure, hierarchical organization, development, cross-cultural validity and differences, connections to other important psychological and behavioral domains and the role of values in our life. The knowledge of values is necessary, yet it is not enough in order to cope with all risks of individual and societal welfare. Another requirement is therefore crucial, namely the abovementioned alignment of values and behavior. Values that are not accomplished or realized in our behavior are useless. Thus, the research of value–behavior relations is extremely important in psychology. It is one of essential pillars in the scientific basis of a stable society and has therefore tremendous practical consequences. It also brings us closer to the perennial question connected with the role of values in our life: does the behavior that is aligned and congruent with values make us happier or not. Thus, the final part of my lecture will be focused on the empirical answers to that question. And, as research results are proving, the life and behavior which are congruent with the values factually correlate with the happiness and general wellbeing.

On Generalized Tree Structures of Artin Groups
Authors: Добрынина И.В. , Угаров А.C.
Published: September 2021

Основными алгоритмическими проблемами теории групп, сформулированными в начале прошлого века для конечно определенных групп, являются проблемы равенства, сопряженности слов и проблема изоморфизма групп.
Исследование данных проблем привело к возникновению комбинаторной теории групп.
Неразрешимость основных алгоритмических проблем в классе конечно определенных групп доказана П. С. Новиковым.
Это привело к рассмотрению алгоритмических проблем в конкретных группах.
К. Аппелем и П. Шуппом в 1983 г. определен класс групп Артина
экстрабольшого типа, где ими решены проблемы равенства и сопряженности слов.
Группы Артина с древесной структурой в 2003~г. введены В.~Н.~Безверхним. В графе, соответствующем группе Артина, всегда можно выделить максимальный подграф, соответствующий группе Артина с древесной структурой. В.~Н.~Безверхним и О.~Ю.~Платоновой решены основные алгоритмические проблемы в данном классе групп Артина.
В статье рассматривается строение диаграмм над обобщенными древесными структурами групп Артина, представляющих собой древесные произведения групп Артина экстрабольшого типа и групп Артина с древесной структурой, объединенных по циклическим подгруппам, соответствующим образующим этих групп, и их применение к эффективному выписыванию образующих централизатора элемента и решению проблемы сопряженности слов в данном классе групп.
В доказательстве основного результата данной статьи используется метод диаграмм, введенный ван Кампеном, переоткрытый Р. Линдоном и усовершенствованный В. Н. Безверхним.

инвариантная относительно движения вдоль траектории системы при
возрастании времени. В этой области установлено существование
единственного стационарного решения
и исследованы вопросы его устойчивости. В настоящее время в связи с экспоненциальным ростом
численности населения, индустриальным прогрессом и,
как следствие, увеличением общего загрязнения биосферы,

практическое и теоретическое значение. Вместе с тем стала
чрезвычайно актуальной проблема качественного исследования
процессов фотосинтеза. В задачах, связанных с фотосинтезом, большой интерес
представляет определение законов функционирования системы,
а также выбор методов математического и компьютерного
моделирования. Фотосинтез является значимым процессом нашей планеты.
Это процесс преобразования поглощенной энергии света в
химическую энергию органических соединений - единственный
процесс в биосфере, ведущий к увеличению энергии биосферы за
счёт внешнего источника - Солнца, обеспечивающего существование
как растений, так и всех гетеротрофных организмов.
Наиболее важными среди внешних факторов, влияющих на
процессы фотосинтеза и фотодыхания, являются температура,
фотосинтетически активная радиация, водный режим, режим
минерального питания растения, а также содержание в
окружающем пространстве углекислого газа и кислорода.
В последние десятилетия наблюдается рост концентрации
углекислого газа в атмосфере и изменение теплового режима
в масштабах планеты. В связи с этим актуальной является
задача прогнозирования изменения интенсивности фотосинтеза
растений, обусловленного изменением концентрации

Теория Титчмарша - Вейля сингулярного уравнения Хана - Штурма - Лиувилля

Published: September 2021

In this work, we will consider the singular
Hahn--Sturm--Liouville difference equation defined by
$-q^{-1}D_{-\omega q^{-1},q^{-1}}D_{\omega ,q}y( x) +v(x) y( x)
=\lambda y(x)$, $x\in (\omega _{0},\infty),$ where $\lambda$ is a
complex parameter, $v$ is a real-valued continuous function at
$\omega _{0}$ defined on $[\omega _{0},\infty)$. These type
equations are obtained when the ordinary derivative in the classical
Sturm--Liouville problem is replaced by the $\omega,q$-Hahn
difference operator $D_{\omega,q}$. We develop the $\omega,q$-analogue of the classical
Titchmarsh--Weyl theory for such equations. In other words, we study the existence of
square-integrable solutions of the singular Hahn--Sturm--Liouville
equation. Accordingly, first we define an appropriate Hilbert
space in terms of Jackson--N\"{o}rlund integral and then we study
families of regular Hahn--Sturm--Liouville problems on
$[\omega_{0},q^{-n}]$, $n\in \mathbb{N}$. Then we define a family of
circles that converge either to a point or a circle. Thus, we will
define the limit-point, limit-circle cases in the Hahn calculus
setting by using Titchmarsh's technique.
The Saga of Teofila Slavery and Credit Circulation in 19th-Century Rio de Janeiro
Authors: Penna Clemente
Published: September 2021

This paper follows the enslaved woman Teofila from captivity to freedom in 19th-century Rio de Janeiro. To become a free woman, Teofila had to navigate the complex private credit networks of the West African community of the Brazilian capital city. With limited banking activity, the cariocas relied on one another for their financial needs, making for a highly convivial credit market that reflected and reinforced the vast inequalities of Brazilian slave society. While following Teofila through the courts of Rio de Janeiro, this paper will demonstrate that one of the cornerstones of the city’s credit market was the presence of an intertwined relationship between credit and private property. The commerce in human beings like Teofila produced thousands of negotiable titles, with slavery working as a propeller for credit circulation and one of its pillars – slave property was the primary collateral for unpaid debts.

The process of controlling the quality of the packaging mold in this final project aims to determine the factors that must be considered, carry out the control process and perform problem solving using a fishbone chart cause and effect diagram. To achieve good print quality, it is necessary to know the problem factors that can affect print quality. This final project focuses on the process of controlling the packaging mold for Aice products. This control process is carried out from the process of icoming the raw materials to the out going of the finished product. This writing uses a descriptive method, which is a writing method that describes and describes the quality control of Aice's product packaging prints. Methods were collected from literature study and observation at PT. Temprina Media Grafika Packaging Bekasi about 3 months. Measurements in quality control use a check list form, color range and cause and effect diagrams fishbone chart. The results of this final project show that in the process of controlling the quality of a good packaging mold, it is necessary to pay attention to factors that can affect quality such as human, material, method, machine and environment. The control process is carried out in several stages, namely control of raw materials, control of the production process, sampling of packaged printed products, controlling the finished product, then solving problems using a fishbone chart cause and effect diagram. To maintain the quality of the products produced, it is necessary to add supporting components in the process of controlling the quality of the mold, increasing optimization of machine maintenance and increasing the skills of human resources.

One of the main components of the fountain solution used for the offset printing technique is isoprophil alcohol (IPA), which is related to its function as a surface tension reducing agent, cooling agent for printing plates and at the same time having anti-bioorganic function. However, complaints have also been made about the weaknesses in the use of IPA related to odor, toxicity and too high evaporation rate during its use. Therefore, in this article, IPA is compared to the "alcohol-free" type when used in the field as a wetting solution mixture using a KBK offset printing machine to produce magazines using of AP 115 paper. The difference in the use of the two surfaces the tension reducing agents are identified by the waste parameters that are used, generated during consistent printing under controlled process conditions. The results obtained indicate that the use of IPA is always higher, but the use of `` non alcoholic '' tends to be more stable in controling the process.Keywords—Isoprophil Alcohol (IPA), alcohol-free fontain solution, offset printing

Inactivation of influenza virus and other potential contaminants like avian adenoviruses coming from embryonated chicken eggs is a critical step in the production of inactivated influenza vaccines. Inactivation must lead to a guaranteed reduction in contaminant titers by at least 4 lg (PFU)/ml. The aim of this study was to identify an optimum cell line for adenovirus propagation and to estimate a reduction in adenovirus titers in vaccine intermediates after inactivation. In a series of experiments, we identified the optimum conditions and the optimum cell line for the propagation of avian adenovirus (strains CELO and Fontes). The most commonly used inactivation methods were analyzed, including inactivation by β-propiolactone and UV light. Viral titers were measured by plaque assays. After 10 h of inactivation with β-propiolactone, CELO titers fell by 4.12 ± 0.06 lg, whereas Fontes titers, by 4.20 ± 0.19 lg, suggesting that β-propiolactone is an effective inactivating agent. Exposure to UV light led to a reduction in CELO titers by 4.69 ± 0.89 lg and a reduction in Fontes titers by 4.44 ± 1.06 lg after 5 min. N-octyl-β-D-glucopyranoside added at the splitting step reduced CELO titers by 0.93 ± 0.15 lg and Fontes titers by 1.04 ± 0.12 lg, whereas tetradecyltrimethylammonium bromide led to a reduction in CELO and Fontes titers by 1.18 ± 0.17 lg and 1.12 ± 0.38 lg, respectively.

The Meaning in Life Measure (MILM) is a new measure for assessing meaning in life by addressing problems associated with existing measures of meaning in life (absence of items related to reflectivity, felt sense, and mattering). For the first time, this study aimed to test the psychometric properties of the MILM for university students in Turkey. We used a sample of 376 university students (Mage=24.03±4.65 years) who participated in an online survey including the MILM, the Adult Dispositional Hope Scale, and the Depression, Anxiety, and Stress Scale – 21. To study the factor structure of the MILM, we firstly employed a dual approach including exploratory and confirmatory factor analysis, which provided support for the goodness of a two-factor model (experience and reflectivity). We secondly tested the convergent and predictive validity of the measure by respectively applying correlation and regression analyses. Our findings supported the convergent validity of the MILM, showing correlations with hope, anxiety, and depression. The predictive validity was also confirmed; the experience subscale of MILM uniquely predicted hope, anxiety, and depression after controlling for covariates (age and gender). Thirdly, our findings showed that the MILM and its subscales had high internal consistency reliability. The Turkish version of the MILM is provided to be a reliable and valid instrument for assessing meaning in life for university students in Turkey.

High on steroids: manic episode after using corticosteroids

This article describes a case of a severe manic episode with a patient using corticosteroids which were one of the precipitating factors.

Since the first use of corticosteroids in medicine, psychiatric side effects as well as a myriad of somatic side effects have been known to occur. The neuropsychiatric side effects are situated within both the affective as well as the psychotic spectrum. While mostly mild and transient, these side effects can be severe, as glucocorticoids increase the risk of suicide to a significant degree.

The risk of developing side effects is dose-dependent and a psychiatric history can be considered a risk factor. The HPA-axis and a potential inbalance between different glucocortoid receptors play a role in causing these side effects.

While convincing evidence exists for the increased risk of psychiatric symptoms caused by systemic use of corticosteroids, far less scientific literature exists regarding the specific treatment.

In addition, the case in this article demonstrates how psychiatric symptoms can severely interfere with the course and treatment of a pneumonia. Such cases remain a challenge in a hospital setting where departments (psychiatry or general medicine) are never completely tailored to the needs of these patients who thereby tend to fall between two stools.

Este primer volumen de la obra "Prospectiva del diseño. Redefiniendo el futuro disciplinar" conjunta parte de las investigaciones más recientes, que surgen de la necesidad de reflexionar acerca del acontecer disciplinar del diseño con miras hacia el futuro. Ante la transformación que estamos experimentando en todas las industrias a escala global, cuyas repercusiones se han hecho más evidentes en las últimas décadas, se torna preponderante debatir sobre el diseño y la importancia de su relación poco explorada con bienes, servicios y experiencias, en un contexto político, económico, sociocultural y tecnológico único. Los trabajos presentados parten de la investigación y reflexión de múltiples prácticas novedosas e iniciativas atractivas que urge considerar como la gestión del diseño, los nuevos retos pedagógicos, el andamiaje metodológico, el diseño paramétrico, la investigación de posgrado, las competencias, los avances tipográficos, estrategias digitales, planes de negocio innovadores, interacciones multisensoriales, la integración en la web, estudios de percepción visual, la realidad aumentada, la usabilidad y la animación. Este Volumen 1 se conforma de quince capítulos, aportaciones internacionales que se dividen en dos partes principales: "Metodología, educación y actividades de formación" y "Aplicación tecnológica y desarrollo económico".

Introduction: Displaced supracondylar fracture in children is a challenging injury that may result in impaired functional and cosmetic outcome if not well-treated. Utilization of Closed Reduction and Percutaneus Pinning (CRPP) increased for this pathology, some authors believe ORIF results better anatomical reduction and lower rate of loss of reduction. Study aims to compare CRPP and ORIF for pediatric supracondylar humerus fracture. Method: Systematic review was conducted based on PRISMA guideline. Inclusion criteria were age <18 years old, comparing CRPP and ORIF for Supracondylar Humerus Fractures Gartland Type II, II.Studies of one surgical technique, Gartland type I, case reports were excluded. For meta-analysis, 6 studies were included and fixed effect model used to pool the result. In each study, mean difference (MD) with 95% confidence interval (CI) was calculated for dichotomous outcomes using Review Manager. Result: Total of 252 patients aged 0-15 years old were included. CRPP more often performed than ORIF. Satisfactory outcomes measured by Flynn’s criteria were achieved in 87.74% in CRPP and 86.73% in ORIF patient group, indicating significant difference (Heterogeneity, I2 = 23%; WMD, 1.26; 0.58 to 2.73; P =0.56). Conclusion: Current systematic review and meta-analysis suggest that for displaced supracondylar humerus fractures, ORIF offers a comparable functional and cosmetic outcome compared to CRPP.
