Sequelae of Unreplaced Tooth Loss in Orthodontic Patients: A Cross-Sectional Study in Najran, Kingdom of Saudi Arabia
Authors: Alyami Bandar 
Published: November 2022

Abstract

Background:
The early tooth loss has an adverse effect on the overall well-being of an individual. The aim of the current study was to highlight the orthodontic complications of long-term tooth loss in the city of Najran.

Materials and Methods:
This was a cohort study of patients presenting for orthodontic rehabilitation. A total of 326 patients that presented for orthodontic rehabilitation were examined clinically and data such as age, gender, number of missing teeth, missing teeth, duration of missing teeth, tipping, and overerupted and rotated teeth were recorded. Patients that can be treated with orthodontic space closure were excluded from the study. Patients’ data were analyzed using IBM SPSS Statistics and results were presented as simple frequencies and descriptive statistics.

Results:
Out of 326 patients that presented for orthodontic rehabilitation, 259 patients had missing teeth with its sequelae that will demand prosthodontic rehabilitation with a prevalence rate of 79.4%. There are 97 (37.5%) males and 162 (62.5%) females with M:F ratio of 1:1.7. The age ranged from 15 to 52 years with mean ± standard deviation (28.5 ± 8.5). The age group 21–30 years constitutes the group with the highest number of missing teeth. A total number of 595 (60.2%) teeth were missing, 173 (17.5%) teeth were tipped, and 124 (12.5%) teeth were overerupted, whereas only 97 (9.8%) teeth were rotated (n = 989). Fixed orthodontic appliances (FOAs) were used for all cases with rotation and FOAs + Mini Screws were used for all cases with tipping, overeruption, and/or combinations. The dental loss was managed by prosthesis depending on patients’ choice and financial capability ranging from removable/fixed prosthesis and dental implants.

Conclusion:
Orthodontic consequences of early tooth loss include tipping and rotation of adjacent teeth and overeruption of opposing teeth. Early acknowledgment of tooth replacement after tooth loss is essential in preventing long-term orthodontic adverse effects.

Published: November 2022

Background:
Temporary anchorage devices or mini-implants have gained great attraction due to its capability to provide absolute anchorage, low cost, versatility, and can be loaded immediately after placement.

Aims and Objectives:
The aim of this study is to use FEA analysis to assess the strain and insertion torque of mini-implants on a bone model at two distinct angulations of 45° and 90°.

Materials and Methods:
A computer-aided three-dimensional (3-D) model representing alveolar bone and mini-implants were developed using ANSYS software. Computed tomography scan images of the implant and the alveolar bone were taken and exported in DICOM format for 3-D image processing. The thickness of the bone model is 1 mm. Ti6Al4V orthodontic single and double threaded mini-implants (L = 7 mm, D = 1.5 mm) were inclined at 45° and 90° on to the bone surface to measure the insertion torque and strain produced.

Results:
Maximum insertion torque (MIT) for single-threaded mini implant at 45° and 90° angulations are 20.001 Nmm and 19.977 Nmm, respectively. MIT for double-threaded mini-implants obtained is 19.977 Nmm at 90° and 19.991 Nmm at 45° angulation. The strain of the bone at 90° angulation for single-threaded mini-implant is 0.00893 mm and for single-threaded mini implant at 45° angulation is 0.01257 mm. The strain in double-threaded mini-implant at 90° angulation is 0.0125 mm and that of 45° angulation is 0.01773 mm.

Conclusion:
For maximum stability single-threaded mini-implant with perpendicular insertion, angle is preferred.

Authors: Pereira Pedro Mariano , Bugaighis Iman , Matos Pedro M. , Porença Luis 
Published: November 2022

AIM:
To evaluate the effect of three different reconditioning techniques on the shear bond strength (SBS) of rebonded brackets.

MATERIALS AND METHODS:
Forty-five orthodontic brackets were bonded to human premolar teeth using Transbond™ XT. After debonding, the samples were randomly assigned into equal groups to assess three techniques for the removal of residual adhesive from bracket bases: in Group A, each bracket base was sandblasted with aluminum oxide; in Group B1, each base was cleaned superficially with a greenstone bur; and in Group B2, the bases were thoroughly abraded with a greenstone bur. Subsequently, brackets were rebonded and the SBS and the adhesive remnant index (ARI) were determined. Data were analyzed using one-way analysis of variance (ANOVA), plus Tukey and Kruskal–Wallis post-hoc tests (P ≤ 0.05).

RESULTS:
The average SBSs were: Group A, 11.75 (±4.83) MPa; Group B1, 8.22 (±4.01) MPa; and Group B2, 7.54 (±2.85) MPa. No statistically significant differences in SBS were found between Groups A and B1(P = 0.051) and Groups B1 and B2(P = 0.885), but there was a significant difference between Groups A and B2(P = 0.016). Regarding ARI scores, there were statistically significant differences between Groups A and B2(P < 0.001) and between B1 and B2(P = 0.014), but not between Groups A and B1(P = 0.068).

CONCLUSION:
All reconditioning methods were found to have a positive effect, but the sandblasting technique performed best. Brackets reconditioned by sandblasting and superficial grinding mainly showed mixed-type failure, while in samples thoroughly reconditioned by greenstone bur, bonding failure occurred predominantly at the adhesive/bracket interface.

Published: November 2022

Background:
Survival and prognostic factors following stroke occurrence differ between world regions. Studies investigating stroke features in the Middle-east region are scarce. We aimed to investigate 1-year survival and related prognostic factors of stroke patients in Central Iran.

Materials and Methods:
It is an observational analytical study conducted on patients registered in the Persian Registry of Cardiovascular Disease-Stroke (PROVE-Stroke) database. Records of 1703 patients admitted during 2015–2016 with the primary diagnosis of stroke in all hospitals of Isfahan, Iran were reviewed. Information regarding sociodemographic characteristics, clinical presentations, medications, and comorbidities were recorded. The living status of patients after 1 year from stroke was considered as 1-year survival.

Results:
Among 1345 patients with the final diagnosis of stroke, 970 (72.1%) were alive at the 1 year follow-up and the mean survival time based on Kaplan–Meier procedure was estimated 277.33 days. The hemorrhagic and ischemic types of stroke were reported in 201 (15.0%) and 1141 (84.8%) patients, respectively. Age (hazard ratio [HR] = 1.07, 95% confidence interval [CI] = 1.05–1.09), diabetes (HR = 1.49, 95% CI = 1.07–2.06), history of stroke or transient ischemic attack (HR = 1.81, 95% CI = 1.30–2.52), history of warfarin usage (HR = 1.73, 95% CI = 1.11–2.71), hospital complications of hemorrhage (HR = 3.89, 95% CI = 2.07–7.31), sepsis (HR = 1.78, 95% CI = 1.18–2.68), and hydrocephalus (HR = 3.43, 95% CI = 1.34–8.79), and modified Rankin Scale (mRS) ≥3 at the time of hospital dicharge (HR = 1.98, 95% CI = 1.27–3.07), were predictors of 1-year survival.

Conclusion:
Predictors of 1-year survival can be categorized into unchangeable ones, such as age, diabetes, previous stroke, and mRS. The changeable factors, such as hospital complications of infection and hemorrhage, guide physicians to pay greater attention to reduce the risk of mortality following stroke.

Published: November 2022

Background:
The aim of this study was to assess the effect of intradialytic cycling exercise on quality of life (QOL) and recovery time in patients who underwent hemodialysis.

Materials and Methods:
Hemodialysis patients were recruited from the referral dialysis centers affiliated with Isfahan University of Medical Sciences, Isfahan, Iran. Patients were randomly assigned into the intervention and the control groups. Patients in the intervention group exercised on a stationary bike for 12 weeks (3 times per week for 30 min); however, patients in the control group received usual hemodialysis. The kidney disease QOL (KDQOL)-short-form version 1.3 was used to assess QOL. Patients were asked to answer the question “How long does it take to recover from a dialysis session?” to assess recovery time.

Results:
A total of 110 hemodialysis patients, including 60 in the intervention group and 50 in the control group were analyzed. A significant increase was observed in the generic (mean difference ± SE: 1.50 ± 0.44, P = 0.001), kidney disease (mean difference ± SE: 0.84 ± 0.28, P = 0.004), and overall QOL (mean difference ± SE: 1.18 ± 0.33, P = 0.001) scores after 12 weeks of intradialytic cycling exercise in the intervention group. Furthermore, a significant difference was noted between the intervention and the control group regarding the mean difference of all QOL scores after the intervention (P < 0.05). We also found a significant difference in the mean difference of recovery time between the intervention and the control group after the intervention (P < 0.001).

Conclusion:
KDQOL and recovery time could improve in hemodialysis patients after 12-week intradialytic exercise.

Published: November 2022

Introduction: Maternal perception of foetal movement ensures foetal wellbeing. Reduced foetal movement is associated with foetal hypoxia, stillbirths, and intrauterine foetal growth restriction (IUFGR). This study aimed at assessing factors that are associated with maternal perception of reduced foetal movements.
Method: This was a cross-sectional study that was conducted at Iringa Regional Referral Hospital from 1st January – 30th June 2022. A purposive sampling technique was used, and SPSS version 25 software was used for data analysis.
Results: 41.3 % of study participants were aged 24 – 34 years, with a mean and SD of 29.08 ±7.53. 75% were not employed, 52.8 % of study participants delivered from 37 – 42 weeks of gestational age, 66.1% had a posterior placenta and only 24.0 % had an anterior placenta. Women who delivered at 28 – 36 weeks of gestational age were about 4 times more likely to experience reduced foetal movement compared to those who delivered at 37 – 42 weeks of gestation (AOR=4.162, 95% CI 2.174 - 7.966, p=<0.0001). Those who attended the Antenatal clinic 2 – 3 times were 2 times more likely to complain of reduced foetal movement compared to those who attended 4 times and above (AOR = 2.655, 95% CI 1.311 - 5.375, p=0.0067).
Conclusion: Reduced foetal movements are associated with lower gestation age at delivery and decreased antenatal clinic attendance in Iringa, Tanzania. All pregnant women should be encouraged to make early antenatal clinic attendance and should attend adequate visits. Healthcare providers should educate and create awareness on methods of assessing foetal movements.

IntroductionGiven the association of inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC), we aimed to investigate the clinical relevance of abnormal hepatobiliary findings on magnetic resonance enterography (MRE) of IBD patients considering the risk of over- or underestimation of PSC at MRE.Material and methodsUsing the MRE dataset of patients referring to a tertiary hospital and the National Registry of Crohn’s and Colitis, 69 MREs, including 23 IBD-PSC, 23 IBD-without PSC, and 23 healthy controls (HC), were retrospectively reviewed by 2 experienced radiologists blinded to the clinical data, to evaluate hepatobiliary abnormalities. Sensitivity, specificity, and likelihood ratios were calculated.ResultsBile duct irregularities were the most common finding in the IBD-PSC group, with a frequency of 91%. Intra- and extrahepatic bile duct (IHBD and EHBD) irregularities were observed in 87% and 78% of PSC patients, respectively. Higher frequency of IHBD and EHBD wall thickening, bile duct dilation, EHBD stricture, and periportal oedema were observed in the IBD-PSC group. Peribiliary T2-weighted hyperintensities and contrast-enhancement were significantly more common in the IBD-PSC group than in the IBD and HC groups (48% and 35%, respectively) (p < 0.001). Detection of biliary irregularities on MRE had a specificity of 94% (95% CI: 82-99%), a sensitivity of 91% (95% CI: 72-99%), and a positive likelihood ratio of 14.0 (95% CI: 4.7-42.1) for the diagnosis of PSC.ConclusionsThis study emphasizes the importance of assessing and reporting hepatobiliary abnormalities visible in the MRE of patients with IBD to avoid a delayed diagnosis of PSC.

Europa, França e Recife: um modernismo de mais de cem anos
Authors: Naslavsky Guilah , Marques Sônia Maria de Barros 
Published: November 2022

Por ocasião das comemorações do centenário da Semana de Arte Moderna de 1922, propomos aqui uma narrativa do Modernismo em Pernambuco que destaca o pioneirismo dos atores com visibilidade internacional mesmo anteriormente à semana paulistana. Adotamos a seguinte periodização: a) o pioneirismo anterior à Semana de 1922 até a década de 1930 e a brilhante atuação do DAC/DAU; b) os anos 1940 e o novo centro no bairro de Santo Antônio; c) os anos 1950-1960 da afirmação disciplinar, com a dupla Amorim-Borsoi; e d) os finais dos anos 1960 aos anos 1970: o brutalismo local e as perspectivas regionais como estratégias defensivas ou expressão de uma nova sensibilidade. Do ponto de vista metodológico, enfatizamos as contribuições individuais, situando-as num quadro mais amplo tanto do ambiente local quanto das relações nacionais e internacionais. Do ponto de vista conceitual, afastamo-nos de perspectivas comparativas eurocêntricas, recorrentes na tradição sociológica brasileira (MARTINS, 2022), que definem a modernidade brasileira pela distinção da europeia, bem como daquelas que caracterizam a modernidade por atributos visuais exclusivistas (GREENBERG, 1961), em prol de uma noção de modernidades diversas.

METHODOLOGICAL FEATURES OF SMARTPHONE SENSORS USING IN PHYSICS SCHOOL LABORATORY WORKSHOP (ON THE EXAMPLE OF THE PHYPHOX MOBILE APPLICATION)
Authors: Voronkin O. S. 
Published: November 2022

У статті акцентовано увагу на використанні датчиків смартфону: акселерометра, гіроскопа, магнітометра, датчика освітленості, мікрофона, барометра та інших в учнівських STEM-проєктах. Запропоновано часткове розв’язання проблеми застарілості матеріально-технічної бази шкільних кабінетів фізики через проведення лабораторних робіт у застосунку Phyphox і 3D-друк допоміжних елементів, попередньо розроблених у середовищі моделювання Tinkercad. Phyphox був розроблений в Університеті RWTH Aachen. Застосунок дає змогу на основі даних, що надходять з датчиків смартфону, створити повноцінний лабораторний комплекс і проводити нетривіальні експерименти, а також зберігати масиви даних для подальшої інтерпретації. Визначено такі особливості застосунку Phyphox: наявність готових фізичних експериментів, можливість створення власних експериментів, опрацювання й унаочнення даних із датчиків смартфону в режимі реального часу, підтримка експорту результатів експерименту у файли різних форматів (csv, xls). Phyphox може керуватися дистанційно з будь-якого пристрою, що перебуває в тій самій мережі, що й смартфон, і має веббраузер. Як приклад розглянуто типові фізичні експерименти, що пропонуються у Phyphox, й авторські ініціативи, як-от: встановлення залежності між освітленістю і збільшенням відстані до джерела світла, встановлення закону руху підвісної гойдалки на основі даних акселерометра, визначення ваги пасажира в кабіні рухомого ліфта, встановлення функції, за якою рівень звуку змінюється зі збільшенням відстані від джерела звуку, дослідження резонансних явищ повітря залежно від об’єму порожнини, визначення швидкості руху радіокерованої автомоделі (на прикладі ефекту Доплера). Перспективним напрямом є проведення лабораторних робіт з використанням зовнішніх датчиків, підключених до платформ Arduino, із синхронізацією зі смартфоном через Bluetooth, що потребує подальших навчально-методичних розробок.

Published: November 2022

During the study of the transformation of the educational process in the COVID-19 pandemic on the example of NSU we identified four main areas of such transformation: 1) transfer of the educational process from classroom classes to online classes using the Portal of educational electronic information systems. In this direction of research the results of data received from the Center of Information Technologies of the University were interpreted, the number of students’ appeals to the portal was compared, their own vision of the obtained results was given; 2) transformation of the work of the scientific library. In this regard, it was determined that the quarantine restrictions associated with the COVID-19 pandemic, the library quickly adapted to changes in the organization of scientific and educational processes at the University, provided a wide range of library and information services, educational activities online / offline. The total number of users on a single account, the number of applications from students for certificates, the number of “physical applications” to the scientific library during the implementation of distance learning were analyzed; 3) increasing the digital competencies of teachers to ensure a quality educational process has become the third area of research. It was found that the digital competencies of teachers in the challenges posed by the COVID-19 pandemic have become important due to the need to ensure a quality educational process and the impossibility of using conventional forms of teaching (teaching disciplines in classroom format, testing papers in paper form) etc). We conducted a survey of students of different courses and faculties on their assessment of digital competencies of teachers. The sample consisted of 509 respondents, representing three faculties: the Faculty of Prosecution, the Faculty of Justice, the Faculty of Advocacy. The results show that in general students rate the digital literacy of teachers above average; 4) increasing the digital competencies of students to acquire knowledge is defined by us as the fourth area of research. The obtained results testify to the importance of mastering digital competencies by teachers and students of the educational institution, the need for their continuous improvement, as well as the relevance of the issues under consideration.
