A Study on the Conversion of Wood Model Widely Used in Lactation to the Model with the Biologically Meaningful Parameters
Authors: KORKMAZ Mehmet
Published: August 2022

A mathematical model is an important instrument used to get information on the attitude of a system. The mathematical models can be used to have a basic knowledge about the working of a system, lowering product costs and improving performance. In this paper, it is stated that the behavior of the system can be better understood by using biologically meaningful parameters in mathematical models. Mathematical models can be divided into two classes as empirical and mechanical models. Since the parameters not biologically menaningful in empirical models, the importance of converting these models to mechanical models containing biologically meaningful parameters has been expressed. The purpose of this manuscript is related to how Wood model widely used in lactation is converted into the model with the biologically meaningful parameters, time to maximum milk production, maximum milk production reached at time to maximum milk production and time to inflection point. For this aim, all the steps of the conversions were given stepwise.

This research was carried out to determine the anti-tumorigenic, antioxidant and antimicrobial activities of extracts obtained from Juniperus oxycedrus L. oxycedrus (Cupressaceae) and Smilax aspera L. (Smilacaceae) fruits. The cytotoxic effects of ethanol extracts of Juniperus oxycedrus L. oxycedrus and Smilax aspera L. fruits were determined with six different tumorogenic cell lines including breast adenocarcinoma, small cell lung carcinoma, osteosarcoma, neuroblastoma and healthy kidney epithelial cells. Among the tested ethanol extracts of Juniperus oxycedrus L. oxycedrus and Smilax aspera L. fruits the ethanol extract obtained from Juniperus oxycedrus fruits was determined to have the highest anti-tumorigenic effect against small cell lung carcinoma with an IC50 value of 7.2 μg ml-1. At the end of cytotoxicity studies, ethanol extracts of Juniperus oxycedrus L. oxycedrus fruits proved to be good candidates for small cell lung carcinoma (A569). Antimicrobial effects were analyzed by the MIC test. MIC values of ethanol extracts of Juniperus oxycedrus L. oxycedrus and Smilax aspera L. fruits against Escherichia coli and Candida albicans were found to be 31.25 μg ml-1. Moreover, the radical scavenging capacity of Juniperus oxycedrus L. oxycedrus and Smilax aspera L. fruit extracts was elucidated. S. aspera L. (61%) and J. oxycedrus L. oxycedrus (47.3%) were found to have good free radical scavenging capacity.

Authors: ONDER Hasan , TIRINK Cem
Published: August 2022

The animal breeding studies rapidly increased over the last century. When the genomic selection tool introduced, scientists and animal breeders have a new area to work with increasing computer power and genomic tolls. In this study, it was aimed to show the situation of last 25 years of the genomic selection studies. Results showed that the number of authors per article showed that the genomic selection is a collobtrative work that its tasks should be shared by gruoup of scientists. Only about 1/3 of the genomic seelction studies related to animal science. Its reason may be hardeness of working with animals ant generation interval which is more easy for plant breeding. When the article issues examined it can be seen that most of the articles were related to dairy science because this method widely use for dairy industry especially to determine candidate sire. The keyword “genomic selection” is widely used even this is a prediction method. It is the proof that the genomic selection is generally accepted idiom. Citation values of the most cited articles also showed that this method mostly affect the dairy science.

California school lead testing results and the new lead and copper rule
Authors: Kimbrough David Eugene
Published: August 2022

Under the revised lead and copper rule, schools and daycare centers will need to conduct lead and copper sampling. The California Division of Drinking Water required Public Water Systems to assist local schools in testing water for lead between 2017 and 2020. There were 43,803 samples collected from 7,058 schools in 864 school districts. In total, 5.2% of the samples had lead present in concentrations greater than the Detection Limit for Reporting (DLR) of 5 μg/L, and 1.1% of samples had lead concentrations greater than the Action Level (AL) of 15 μg/L. When broken down by counties, these patterns are consistent throughout most of the State. Drinking fountains had significantly lower frequencies of results above the DLR and AL than samples collected from sinks and food preparation areas. Chloride, bicarbonate, and pH appeared to influence the frequency of results above the DLR and AL.

Background:

Electrical resistivity tests at a project site could be a valuable economical alternative to typical geotechnical soil exploration and a reliable source of data. In the present study, the soil at a constructed underground water tank site in Qassim Region – Saudi Arabia is investigated using the electrical resistivity testing method.

Objective:

The study aims to compare the results of traditional soil boreholes that were conducted at various stages of the project lifetime with the interpretation of soil resistivity test results.

Methods:

Eight soil boreholes were drilled at the water tank site to capture the nature of soil layers. The electrical resistivity of soil layers at the site is measured and used to investigate the ground subsurface of the project site. The geophysical software, ZondRes2d is utilized to analyze and interpret the collected data.

Results:

Both geotechnical soil boreholes and geophysical electrical resistivity tests revealed similar soil profiles with three main layers comprising of backfill material, clay with expansive nature, and weathered limestone and marl. The results of the electrical resistivity tests are also affirmative of available resistance values of different soils in the literature.

Conclusion:

The study shows that electrical resistivity testing is reliable in capturing the soil nature which presents an attractive tool for preliminary investigation of the soil-related problems of distressed structures.

Authors: Lakshmi Raj , Chitra A. , Singh Anupam , Pentapati Kalyan C , Gadicherla Srikanth
Published: August 2022

Background:

This study aimed to assess the difference in the recovery pattern of branches of infraorbital nerve paraesthesia after zygomaticomaxillary complex (ZMC) fracture in both surgically and non-surgically managed patients.

Materials & Methods:

A prospective, observational study involving 31 patients with unilateral ZMC fracture - 15 in the surgical group (Group A) and 16 in the non-surgical group (Group B) was evaluated. These patients were assessed at the time of injury, 3-months follow-up, and 6-months follow-up for the sensory function of the infraorbital nerve. The assessment of paraesthesia by cotton wisp test, light touch monofilament test, and the cold thermal test was subjected to intra-group and inter-group correlation by McNemar test and Fischer's exact test. Repeated Measures ANOVA with post-hoc Bonferroni test for intra-group correlation and independent sample t-test for inter-group correlation were used for two-point discrimination.

Results:

A statistically significant improvement was noted on both 3 and 6 months follow-up in the malar region in group A. Other statistically significant improvements were noted only on 6 months follow-up in the infraorbital region in group A. On the 2-point discrimination test, all the facial regions showed significant improvement in both the groups over 3 months and 6 months of follow-up.

Conclusion:

There was a significant improvement in the infraorbital nerve sensory function following ZMC fracture over 6 months; however, the surgical intervention showed no statistical significance. Further, it can also be concluded that the inferior palpebral branch of the infraorbital nerve shows maximum functional disruption resulting in a higher incidence of paraesthesia in the infraorbital and malar region.

Published: August 2022

Aims:

This study evaluates the educational crew of dental faculty’s lived experiences facing obstacles and requirements in institutionalizing performance assessments to implement a professional competency-based evaluation system.

Background:

The competency-based evaluation of learning and teaching processes has been adopted as a key policy in the developed world, which indicates the achievement rate of educational goals and the quality of education.

Objective:

The main objective of this study was to evaluate obstacles in institutionalizing performance assessments for the educational crew.

Methods:

This qualitative study used a semi-structured interview in a focus group discussion. The experience of the educational crew regarding the obstacles of using performance assessments and their approaches to conducting a professional competency-based evaluation was assessed. The recruited participants were educational supervisors, professors of orthodontics and prosthodontics, and the medical education department and evaluation committee members of the faculty of dentistry at the University of Tabriz. The purposive sampling technique was used and continued until reaching saturation. Five focus group discussions were conducted with fourteen educational crew and three medical education department members. The data were analysed using thematic analysis.

Results:

The interview analysis results yielded 450 codes in three general categories, including “current condition of clinical education,” “obstacles of implementing new evaluation methods,” and “requirements for effective evaluation of clinical skills.” According to the results, changes in evaluation methods are necessary to respond to community needs. There are also many cultural problems with applying western models in developing countries.

Conclusion:

The medical community should be directed towards a competency-based curriculum, especially in procedure-based fields, such as dentistry.

Other:

They are moving towards altering traditional evaluation methods (the traditional classroom-based lectures). This paradigm change requires support from the department and the provision of infrastructure.

Published: August 2022

Background

The COVID-19 pandemic has accelerated the changes of daily practice in medical care worldwide. Telemedicine is one of the most stimulated fields among these changes, even in the cardiovascular disease care. In the past decade, remote monitoring has become an important tool that provides valuable clinical information via respiratory assist devices and implantable pacemakers from patients at home.

Objective

The objective of our study was to investigate whether these remote monitoring approaches could include a broader spectrum of patients with cardiac disease with the development of noninvasive monitoring devices.

Methods

Several pilot studies of telemedicine-based monitoring systems using commercially available digital devices were conducted in the infectious disease wards and other clinical settings during the COVID-19 pandemic. We evaluated the effectiveness of a remote heart monitoring system that provides real-time electrocardiogram and other vital signs monitoring in patients with cardiovascular disease. A newly developed remote cardiac rehabilitation system was also evaluated.

Results

We found that current remote monitoring technology could provide sufficient monitoring of vital signs, suggesting a potential to predict a worsening of heart failure in advance. Remote cardiac rehabilitation could be effectively and safely provided in patients with low to medium risk.

Conclusions

Telemedicine and remote cardiac rehabilitation possess a great potential in the cardiovascular disease practice post COVID-19 era; however, there are several unsolved issues regarding their implementation in the real-world clinical practice.

Published: August 2022

The potentials of lactic acid bacteria serum, termed as ‘Lactobacillus (LB) serum’, in enhancing soil nutrient availability and supplies for the growth of Amaranthus hybridus and some chemical properties of soil were investigated at the screen house of the Department of Soil Science, University of Benin. Three application rates of the serum were adopted, consisting of 3 mL (3,000 L.ha-1), 5 mL (5,000 L.ha-1), and 0 ml (0 L.ha-1), and represented as treatment. Amaranthus hybridus was transplanted into pots containing 2 kg of 2 mm sieved air-dried soil. Each treatment was replicated seven times to give a total of 21 pots that were laid out in a Completely Randomized Design (CRD). The treatments were applied twice a week starting from the 2nd week after transplanting. The plant growth indices measured were number of leaves, plant height and plant biomass. The results showed that serum positively influenced the number of leaves and plant biomass (4.333 kg to 4.830 kg) compared to the control (3.901 kg). However, the highest value of the plant biomass was found in the 3 mL (3,000 L.ha-1) treated pots, while the microbial colonies of bacteria in soil after serum application were sustained when compared with the control but at a reduced population for Bacillus subtilis. The application of LB. serum slightly improved the soil total organic carbon (320.0 g.kg-1 to 352.0 g.kg-1) and nitrogen (3.102 g.kg-1 to 3.325 g.kg-1) as against, 64.00 g.kg-1, and 0.639 g.kg-1 in the control respectively.

Published: August 2022

Recently, four quantitative trait loci linked to flesh mealiness in apples were identified, with one associated with the MdPG1 allele. Hence, this study analyzed cell wall changes in two mealy (Orin and Akane) and three non-mealy (Kiou, Kitaro, Fuji) apple cultivars during ripening. The fruits were harvested for each cultivar at optimum maturity and stored at 20°C for 20 days. The flesh firmness of ‘Kitaro’ and ‘Fuji’ fruit did not change strikingly over the 20 days, whereas that of the other three cultivars, especially ‘Akane’ and ‘Orin’, gradually decreased during ripening. Between the two cultivars with a mealy texture, ‘Akane’ fruit produced extremely low levels of ethylene, whereas ‘Orin’ fruit produced high levels. The water-soluble polyuronide (WSP) contents of ‘Kiou’ and ‘Fuji’ fruit did not change clearly. In contrast, the WSP contents of the other three cultivars, especially ‘Akane’ and ‘Orin’, increased during ripening. In ‘Kiou’, ‘Kitaro’, and ‘Fuji’ fruit, the molecular-mass distributions of WSPs did not change during ripening. Conversely, the molecular-mass distribution of WSPs in ‘Akane’ and ‘Orin’ fruit exhibited downshifts during ripening. These results indicate that solubilization and depolymerization of pectic polyuronides occur during ripening in mealy ‘Akane’ and ‘Orin’ fruit, and that ethylene may not be involved in these changes.
The Pivotal Role of Performance-Based Assessment in EFL/ESL Classrooms: A Critical Appraisal
Authors: Altukruni Raja Ahmed
Published: August 2022

Assessment plays a central and important role in teaching and learning as it measures and estimates whether learners achieved the desired goals and met the expectations; and therefore, instructors can make decisions regarding instruction, curricula, and learners’ proficiency and placement. Nevertheless, there is no single assessment tool which is fully adequate to provide both instructors and students with all the information needed to make judgments about learners’ actual abilities; however, performance-based assessment (PBA) is considered as one of the effective alternative and authentic assessments for evaluating students’ English competence. This paper is an appraisal of the washback effect of PBAs in EFL/ESL classrooms and the potential challenges faced by instructors when implementing PBAs. It provides a comprehensive review of literature relating to L2 assessment; compares between different modes of assessment; discusses the benefits and drawbacks of PBAs; and provides general guidelines for an optimal design and implementation of PBAs in language classrooms.
Evaluation of relationship generated between concrete fiber properties and permeability
Authors: AL-obaidi Abdullha Mudhafar Shawka
Published: August 2022

The research aims to Evaluation of a relationship generated between concrete fiber properties and permeability. All concrete samples were examined in Baghdad, Iraq, where 8 samples for beams were collected distributed on cutting and flexural tests, and 16 samples were collected for the cylinder distributed on compression and tensile strength tests. The study found that fibrous concrete reduces permeability and thus reduces water bleeding, as some types of fibers produce greater impact and resistance to abrasion and fracture in concrete. In general, fibers do not increase the flexural strength of concrete, so they cannot replace structural or resistive rebar, some fibers reduce the strength of concrete. This can be explained from the general concept of the mechanism of action of the fibers inside the manufactured concrete, which, when exposed to stresses, works to form connecting bridges through the internal cracks in the concrete, which may contribute to creating additional resistance after the cracks occur.

Authors: Kalaiselvan Anbarasi , Krishnan Padma , Selvam Esther Mary
Published: August 2022

Staphylococcus haemolyticus is a highly resistant opportunistic pathogen having close genomic relatedness with other virulent species of staphylococci. However, compared to Staphylococcus aureus and Staphylococcus epidermidis, little is known about the resistance genes of S. haemolyticus. The purpose of this study was to characterise antibiotic resistance genes in S. haemolyticus isolates. Standard microbiological techniques were used to identify and confirm 104 S. haemolyticus isolates included in the study. Antibiotic susceptibility testing and D-test were performed, followed by PCR amplification of various resistance determinants (mecA, ermA, ermC, msrA, aac(6′)-Ie-aph(2″), ant(4′)-Ia,aph(3′)-IIIa, tetK, tetM, dfrA, fusB, fusC, fusD and mupA). Methicillin resistance was observed in 93.3% of study isolates. The maximum number of isolates showed resistance to erythromycin (n=79, 76%), followed by ciprofloxacin (n=66, 63.5%) and cotrimoxazole (n=58, 55.8%). In the D-test, 8 isolates showed inducible (iMLSB) and 11 showed constitutive (cMLSB) resistance. Among the resistance determinants, mecA gene (93.3%) was the most prevalent, followed by dfrA (50.5%). Furthermore, aac(6’)-Ie-aph(2’’) and aph(3’)-IIIa combination was observed in 26.9% of isolates, and aac(6’)-Ie-aph(2’’) alone was present in 3.8% of isolates. Among the study isolates, 17.3% exhibited tetK gene, whereas only 1% exhibited tetM; a combination of tetK and tetM was observed in one isolate. The fusB and fusC were present in 11.5% of isolates, and 12.5% of the isolates were positive for mupA. In conclusion, the present study underlines the concern of increasing antibiotic resistance among S. haemolyticus isolates. Avoiding misuse/overuse of antibiotics along with continuous surveillance programs can reduce the spread of antibiotic resistance.

Published: August 2022

This study uses the latest data and data concepts to replicate and validate Sugimoto and Thelwall’s 2013 analysis of the impact of media platforms on scientific and scholarly communication and the dissemination of scientific research. The current study analyzes the use of 1491 TED Talk videos—videos frequently used to communicate scientific research and scholarship—on two platforms: the TED website and YouTube. The results suggest that the impact of the videos on knowledge dissemination was stronger across four metrics than in Sugimoto and Thelwall’s study and that art and design videos continue to receive less attention than other types of videos (e.g., science and technology). Also, academic speakers received more comments than other types of presenters. To improve science communication with videos, we offer suggestions drawn from this research to help presenters better communicate science through the use of online videos. Résumé Cette étude recourt à des données récentes et à des concepts sur les données récents pour reproduire et valider une analyse effectuée par Sugimoto et Thelwall en 2013 sur la manière dont les plateformes médiatiques influencent la communication savante et la diffusion de la recherche scientifique. Notre étude analyse l’utilisation de 1 491 vidéos de TED Talk—fréquemment utilisées pour communiquer la recherche et le savoir scientifiques—sur deux plateformes : le site web de TED et YouTube. Les résultats suggèrent que l’impact des vidéos sur la diffusion des connaissances était plus fort sur quatre paramètres clés que dans l’étude de Sugimoto et Thelwall et que les vidéos sur l’art et le design continuent de recevoir moins d’attention que d’autres types de vidéos (par exemple, celles sur la science et la technologie). De même, les présentateurs académiques ont reçu plus de commentaires que d’autres types de présentateurs. Afin d’améliorer la communication scientifique par vidéos, nous faisons, en guise de conclusion, des suggestions basées sur notre recherche pour aider les présentateurs à mieux parler de science au moyen de vidéos en ligne.

Authors:   Vytautas Magnus University, Juskys Dominykas , Zozaite Rasa
Published: August 2022

In 1918, two entirely different states had emerged in Europe – Lithuania and Belarusian National Republic. In comparison, these two countries are similar in geopolitical and historical sense. However, after declaration of independence, the attempt of Lithuania and BNR to govern and preserve nationalistic ideas had opposite results. By analysing historical context of the early 20th century in Lithuanian and Belarusian lands, general picture reveals that major geopolitical events, internal societal conditions and cohesion differed in both states, eventually affecting emancipation of national ideas. Nonetheless, the level of governance, unity of political and institutional actors, as well as success decided fates of BNR, which dissolved by the end of the same year.

Pēc valstiskās neatkarības iegūšanas (1918) radās piemēroti apstākļi kokles attīstībai: dažādas inovācijas bija vērojamas gan instrumenta uzbūvē, gan spēles paņēmienos un repertuārā. Raksts ir pirmā publikācija, kas daudzpusīgi apskata kokļu modernizācijas priekšnoteikumus un tās izpausmes izraudzītajā laikposmā. Šai nolūkā apkopota un analizēta iepriekš dažādos avotos izklaidus pieejamā informācija, kas veltīta kokļu būvei un spēlēšanai Latvijā 20. gs. 20.–30. gados.

Published: August 2022

Lai veicinātu Latvijas atzīšanu, Latvijas valdība 1921. gadā nosūtīja uz ASV oficiālu delegāciju Ludviga K. Sējas vadībā. 1922. gada janvārī darbu Ņujorkā uzsāka karjeras konsuls Arturs B. Ļūļe. 1922. gada 28. jūlijā ASV atzina Latvijas Republiku de iure un delegācija ieguva sūtniecības statusu. 1923. gada aprīlī sūtniecību slēdza. Raksta mērķis ir sniegt ieskatu par pārstāvniecības prioritārajiem uzdevumiem atzīšanas veicināšanā, kā arī pārstāvniecības slēgšanas apstākļiem. Rakstā uzsvērtas svarīgākās L. Sējas publikācijas laikrakstos un 1922. gadā izveidotās Baltijas–Amerikas biedrības aktivitātes. Autore secina, ka pārstāvniecības slēgšana saistīta kā ar finanšu optimizāciju, tā arī Latvijas ārlietu modeļa, kas balstījās uz plaša konsulārā tīkla izveidi, ieviešanu.

Представлена прикладная теория, описывающая поперечные колебания кантилеверного биморфа в переменном магнитном поле. Биморф изготовлен из пьезоактивного материала, представляющего собой многослойный композит с чередующимися пьезоэлектрическими и пьезомагнитными слоями. Механические и физические свойства такого композита задаются эффективными константами. Подобная конструкция может служить моделью устройства накопления энергии, находящегося под действием внешнего переменного магнитного поля. В рамках теории приняты квадратичные распределения электрического и магнитного потенциалов по толщине, а также учтены неоднородности в продольном направлении. Проведены расчеты напряженно­деформированного состояния биморфа, распределения электрического и магнитного полей, а также собственных частот. Рассмотрен случай, когда потенциал на одном из электродов неизвестен. Проведено сравнение результатов расчетов в области низких частот с результатами конечно­элементной модели на основе системы уравнений в частных производных, решенной в пакете COMSOL Multiphysics. Сравнение показало хорошее совпадение результатов расчета характеристик поля с данными конечно­элементного моделирования во всей области биморфа, за исключением окрестности заделки и свободного конца.

Предложен метод изучения смятия однонаправленного композитного материала на основе вычислительной микромеханики. Микромеханическая модель использована для изучения упругости и прочности однонаправленного композитного материала в условиях работы на смятие под крепежным элементом. Модель имитирует результаты испытаний на полуобразце с отверстием диаметром 6 мм. На модели, учитывающей только геометрическую нелинейность, показано влияние трения контакта и дефектов волокна на модуль упругости смятия. На модели с упругопластическими свойствами матрицы показаны особенности образования полос кинкинга волокон и выявлена последовательность разрушения при смятии. Полученные закономерности могут быть учтены при создании модели разрушения обобщенного материала слоя и изучении смятия на разнонаправленных укладках.

Представлены данные экспериментального исследования возможности рециклинга полимерных композитов на примере стеклопластика из полотняной стеклоткани и эпоксивинилэфирного связующего. Цель рециклинга — удаление полимерной матрицы и получение восстановленного стекловолокна, не уступающего по свойствам первичному материалу. Рассмотрен метод сольволиза композита в среде метилдиэтаноламина. Установлена зависимость влияния времени сольволиза и содержания гидроксида щелочного металла в реакционной среде на прочность восстановленных стеклянных волокон. Оптимальным принят режим сольволиза при температуре 180 °С и концентрации катализатора 5% в течение 6 ч. В результате определен режим, позволяющий получать волокна с разрывной прочностью 92% прочности первичных волокон. Восстановленные ткани исследованы методами термического анализа и растровой электронной микроскопии. Из восстановленных тканей получены образцы стеклопластиков методом VaRTM. Прочность при трехточечном изгибе композитов из вторичного наполнителя на 8,5% ниже, чем такого же материала на основе первичной ткани.

Неустойчивость композитных пластин, подверженных произвольной периодической динамической нагрузке, исследована с помощью теории сдвигового деформирования высокого порядка. Дифференциальные уравнения движения типа Матье получены с применением принципа Гамильтона и метода Галеркина. С помощью метода Болотина оценили частоты возбуждения композитных пластин для определения их области неустойчивости и индекса динамической неустойчивости. Игнорируя члены высокого порядка поля перемещений, систему определяющих уравнений пластин можно упростить до теории первого порядка. Результаты динамической неустойчивости композитных пластин, определенные с помощью предложенной теории, сравнили с рассчитанными по теории пластин первого порядка. Анализ показал, что члены высокого порядка оказывают существенное влияние на динамическую неустойчивость композитных пластин.

Published: August 2022

Fibrolipomas are a rare microscopic variant of lipomas, characterized by mature adipose tissue interspersed with dense fibrous connective tissue. These lesions are rarely observed in the head and neck region and represent <0.6% of all benign tumors of the larynx and hypopharynx. Their clinical presentation depends on the location and size of lesions. Patients present with variable symptoms; however, fibrolipomas of the larynx and hypopharynx are clinically important because these tumors can cause unpredictable airway obstruction, particularly during general anesthesia induction. We present a case of a hypopharyngeal fibrolipoma in a 61-year-old patient with frequent dyspnea, dysphagia, and muffled voice. Laryngoscopy revealed a well-demarcated pedunculated ovoid mass involving the larynx. We performed laryngomicrosurgery using a carbon dioxide laser for surgical excision and subsequent evaluation confirmed the diagnosis of fibrolipoma. We report a case of hypopharyngeal fibrolipoma, together with a literature review.
A Case of Voice Therapy for Long Standing Functional Aphonia
Authors: Kim Bo Ram , Woo Joo Hyun
Published: August 2022

Functional aphonia is a disease in which normal vocal ability is suddenly lost. When voice therapy is started at an early stage, the prognosis is good. However, if the functional aphonia persists for a long time, there is a possibility that the voice disorder may become fixed, though reports of these characteristics are rare. The authors experienced a patient with functional aphonia that occurred in adolescence and lasted for 7 months and reported the result of treatment.

Background and Objectives The quality of life after thyroidectomy, such as voice change, is considered to be as important as control of the disease. In this study, we aimed to evaluate changes in both subjective and objective voice parameters after thyroidectomy resulting in normal morbidity of the vocal cords.Materials and Method In this prospective cohort study, 204 patients who underwent thyroidectomy with or without central neck dissection at a single referral center from Feb 2015 to Aug 2016 were enrolled. All patients underwent prospective voice evaluations including both subjective and objective assessments preoperatively and then at 2 weeks, 3, 6, and 12 months postoperatively. Temporal changes of the voice parameters were analyzed.Results Values of the subjective assessment tool worsened during the early postoperative follow-up period and did not recover to the preoperative values at 12 months postoperatively. The maximal phonation time gradually decreased, whereas most objective parameters, including maximal vocal pitch (MVP), reached preoperative values at 3–6 months postoperatively. The initial decrease in MVP was significantly greater in patients undergoing total thyroidectomy, and their MVP recovery time was faster than that of patients undergoing lobectomy (p=0.001). Patients whose external branch of the superior laryngeal nerve was confirmed intact by electroidentification showed no difference in recovery speed compared with patients without electroindentification (p=0.102), although the initial decrease in MVP was lower with electroidentification.Conclusion Subjective assessment in voice quality and maximal phonation time after thyroidectomy did not show recovery to preoperative values. Aggravation of MVP was associated with surgical extent and electroidentification.
