Authors: Thanikachalam Ramesh , Elangovan Sathyan , Grace Jercy
Published: March 2023

Background: Hepatitis B virus (HBV) infection affects more than 2 billion individuals globally HBV. The chance of dying from liver cirrhosis, acute fulminant liver disease, or hepatocellular carcinoma (HCC) is present in 240 million of these chronic HBV carriers(HCC).
Aims and Objectives: This study aims to assess the anti-HBs antibody titer level against various levels of healthcare workers (HCWs) and to assess the need for booster dose hepatitis B vaccination.
Materials and Methods: This study was conducted at Melmaruvathur Adhiparasakthi Institute of Medical Sciences and Research, Melmaruvathur, Tamil Nadu, India, from July 2022 to December 2022. A total of 218 HCWs were divided into two groups: Group A (vaccinated ≥5 years ago) and Group B (vaccinated in past 5 years). The serum from 2 mL blood was separated and tested for anti HBs antibody titer by electrochemiluminescense immunoassay method.
Results: The mean and standard deviation values of Anti-HBsAg titer between Group A and Group B was not statistically significant (P=0.08467).
Conclusion: Our study demonstrates that people who have had vaccinations are unsure of whether they are responders or non-responders, and to determine this, they must have had their titer evaluated only 1–2 months after receiving their third dosage of hepatitis B vaccine. As a result, they still run the risk of contracting hepatitis B and strongly need a booster dose of the hepatitis B vaccine.

DESIGN OF NEW COMPOUND RECONFIGURABLE MICROSTRIP ANTENNA FOR C AND KU BANDS APPLICATIONS
Authors: Al-Tamimi Mushreq , Hamdan Thaher Raad
Published: March 2023

A compound reconfigurable microstrip antenna has been analyzed and designed using switching a PIN diode to switch between different modes of operating frequencies as well as radiation pattern directions. In this paper, computer simulation technology (CST) software 2020 has been used. Due to the complex calculation of the circular microstrip patch antenna, the proposed design has reduced the complexity by using a structure that is compact, easy to fabricate, cheap to produce, and uses only one PIN diode, while maintaining peak antenna performance. The suggested design is appropriate to operate in two states conditional on biasing the PIN diode. The reconfigurable patch of 31.16 mm × 27.04 mm has a compact size with 1.6 mm of thickness. It functions in both the C band at 7.1 GHz with a shift of radiation pattern direction to 4 degrees and in the Ku band at 12.5 GHz with a shift of radiation pattern direction to 28 degrees in state 2 where the PIN diode is on the state. In addition, the ON and OFF state of the switching PIN diode has been extensively investigated by changing the resistance, inductance, and capacitance values for optimal antenna performance. The proposed reconfigurable circular patch can be implemented to operate in modern communication such as Radio navigation and earth exploration, space operation, earth-to-space satellite communication, 5G applications, and Wireless-Fidelity 7.

Published: March 2023

It is becoming increasingly popular to manage agricultural wastes in an environmentally friendly manner and to take advantage of this waste by manufacturing a product with good properties and a high carbon percentage and then using it as a substitute for a variety of materials and fillers in several industrial and environmental applications. This process has become increasingly popular as awareness of environmental issues has grown. This study aimed to characterize and evaluate the amount of carbon that was present in the sample. The physicochemical characteristics of biochars produced from sesbania stems that were pyrolyzed at a temperature of 400 degrees Celsius for a period of 0.5, 1, 1.5, and 2 hours. The characterizations of biochar produced from sesbania are done by Energy dispersive spectrometer and Fourier transforms infrared spectroscopy. It was found that as the pyrolysis residence time grew, the yield of biochar and the functional groups decreased, however, the amount of fixed carbon content increased, and all these effects contribute to the volatile matters that are present in the material. SSB is going to be an invaluable resource for applications in which high carbon content is required, as well as for use as a filler in a variety of composites.

2020 was a year when international trade activities are not favourable. However, Vietnam still ranked in the group of countries with the highest growth in the world. And prominent in that economic picture is Vietnam’s export activities. Therefore, it is really urgent to find suitable solutions to help export continuously maintain its role as the key engine of growth in the context of increasingly complex disease developments. To assess the impact of the epidemic and some macro factors on export activities, this study used regression models for panel data with latent variables to measure main factors: supply, demand, motivation, and barriers to Vietnam’s export activities in the period 2012-2020 through exploratory factor analysis method. The obtained results have shown the effectiveness of combining the factor analysis method in estimating regression models by the ordinary least square (OLS) method, especially in the context of big data, along with the rapid increase in the dimension of the observed variables.

Published: March 2023

Vietnam and Angola have established official diplomatic relations since November 12, 1975. After 47 years of cooperation, Angola has become one of the important partners of Vietnam in the African region. Medical cooperation between the two countries has been established since the signing of the Agreement on Cooperation in the health sector in 1984. By analysing the relevant sources of documents, the research aims to evaluate the status of medical cooperation between the two countries in areas such as exchange of experts, medical equipment support, and cooperation in disease prevention and control, thereby drawing out lessons learned about the potential of cooperation between Vietnam and Angola in the future. At present, the Angolan government is still in need of expanding and further promoting cooperation in the exchange of medical experts, mobilising the support of medical equipment and disease prevention and control from Vietnam. In the coming time, if barriers can be minimised and potentials and prospects can be promoted, bilateral cooperation in the healthcare sector will be more successful.
Ефективність консервативного лікування у дітей з екзотропією залежно від стану зорових та бінокулярних функцій до лікування
Authors: Бойчук Ірина , Тарак Алуі
Published: March 2023

Вступ. Екзотропія – це порушення положення очей, яке характеризується відхиленням ока або очей назовні внаслідок вроджених або набутих аномалій у будові орбіт та очних яблук, аномалій прикріплення чи розташування очних м’язів. Для консервативної терапії екзотропії використовуються такі методи, як «надмінусові» лінзи, терапія з призмами, оклюзійна терапія, хірургія екстраокулярних м’язів та ортоптична терапія зору.
Мета. Оцінити ефективність консервативного лікування екзотропії залежно від стану зорових та бінокулярних функцій до лікування.
Матеріал і методи. Під наглядом знаходився 51 пацієнт з екзотропією віком від 10 до 21 року. З них постійну форму екзотропії мали 24 (47,05%) пацієнти, періодичну – 27 (52,95%). Кут екзотропії не перевищував 15°, в середньому – 11,8°±3,12° по Гіршбергу. Всім хворим було проведене загальноприйняте офтальмологічне обстеження, а також визначена найближча точка конвергенції, співвідношення акомодаційної конвергенції до акомодації (АК/А), фузійні резерви та бінокулярний зір для далекої та близької відстаней, стан стереозору. Лікувальні процедури включали оптичну корекцію, плеоптику та пряму оклюзію ведучого ока за наявності амбліопії, ортоптодиплоптичне лікування спрямоване на відновлення та укріплення бінокулярних функцій.
Результати. Після лікування кут косоокості для далекої та близької відстані значно зменшився у групі з постійною екзотропією (р = 0,0001 та р = 0,0065 відповідно) та у групі з періодичною косоокістю для далекої відстані (р = 0,0001), але несуттєво для близької відстані. Бінокулярний зір відновився в обох групах: при постійній формі екзотропії у 38% та періодичній – у 70% випадках. Показники конвергенції та АК/А не зазнали суттєвих змін, хоча й наблизились до нормальних величин. Фузійні резерви значно збільшились в обох групах екзотропії. Стереозір відновився за тестом Ланга для близької відстані, але для далекої відстані у групі з періодичною косоокістю наявність стереозору відзначена лише у 65% випадків (р = 0,01). Після лікування ортотропія була досягнута у 62,7% дітей з кутом девіації менше ніж 12,0 призмальних (пр.) дптр (6°). Кут девіації понад 12,0 пр. дптр залишався у 37,3% хворих, яким згодом було виконане хірургічне втручання. Виявлено 4 основних показники, стан яких визначає сприятливість результатів консервативного лікування – найближчі точки конвергенції, фузія на синоптофорі, АК/А, стереопоріг за тестом Ланга II. Але у 37,3% хворих згодом було виконане хірургічне втручання.

Authors: Сидорчук Уляна , Новицький Ігор
Published: March 2023

Актуальність. Вторинна неоваскулярна глаукома (НВГ) належить до рефрактерних глауком із низькою ефективністю хірургічного лікування.
Мета. Порівняти ефективність трабекулоектомії з формуванням фільтраційного каналу (ТЕ) та імплантації шунту Ex-PRESS у хірургічному лікуванні НВГ із застосуванням anti-VEGF препаратів.
Матеріал і методи. Прооперовано 32 пацієнти (32 ока) з НВГ. Середній вік пацієнтів – 65,2±10,1 років. Причиною НВГ у 22 випадках був цукровий діабет, у 10 випадках – тромбоз центральної вени сітківки або її гілки.
У першій групі (23 пацієнти) проведено модифіковану нами ТЕ, у другій групі (9 пацієнтів) – операцію з імплантації міні-шунту Ex-PRESS. Показанням до операції була некомпенсація (більше ніж 26 мм рт. ст.) внутрішньоочного тиску (ВОТ) на максимальній гіпотензивній терапії. За 3–5 днів до операції проводилася інтравітреальна ін’єкція ранібізумабу в дозі 0,5 мг.
Результати. Через 3–5 днів після інтраокулярної ін’єкції ранібізумабу відмічена повна або часткова редукція новоутворених судин райдужки. ВОТ у всіх прооперованих хворих до операції становив 30,9±7,1, на 7-ий день після операції ‒ 17,0±3,6, а через 12 міс. ‒ 22,1±2,9 мм рт. ст. При цьому в групі з ТЕ ВОТ до операції був 31,3±8,4 мм рт. ст., через 7 днів ‒ 16,7±3,7 мм рт. ст., а через 12 міс. ‒ 21,6±2,5 мм рт. ст., у групі з Ex-PRESS до операції – 30,0±1,7 мм рт. ст., через 7 днів – 18,0±3,2 мм рт. ст., а через 12 міс. ‒ 23,3±2,3 мм рт. ст.
Кількість гіпотензивних препаратів, які використовували всі пацієнти до операції, становила 2,4±0,7, через 1 міс. після операції ‒ 1,3±0,6. У групі з ТЕ вона становила до операції 2,4±0,8, а через 1 міс. після операції – 1,0±0,6, у групі з Ex-PRESS до операції – 2,6±0,5, а через 1 міс. ‒ 1,5±0,7.
Висновки. Розроблена нами модифікація ТЕ з формуванням фільтраційного каналу в комбінації з передопераційним інтраокулярним уведенням ранібізумабу в дозі 0,5 мг є ефективним хірургічним втручанням у разі НВГ, за ефективністю не поступається імплантації шунту Ex-PRESS із передопераційним інтраокулярним уведенням ранібізумабу.

В огляді висвітлено розділ вітреоретинальної хірургії – хірургічне лікування ідіопатичних розривів макули (ІРМ). Метою огляду є оцінювання сучасних методик лікування ІРМ і прогностичний аналіз закриття розривів у післяопераційний період. ІРМ є анатомічним дефектом фовеолярної ділянки сітківки ока, що призводить до зниження центрального зору. У роботі розглянуто питання етіології та патогенезу, класифікації, історичні аспекти методів хірургічного лікування й сучасні підходи до лікування ІРМ. Основну роль у розвитку патології відіграють тангенціальні вітреомакулярні тракції. Класифікація розривів макули ґрунтується на даних біомікроскопії та ОКТ-сканування. Аналіз літературних джерел свідчить, що вітреоретинальна хірургія має значний арсенал методик лікування ідіопатичних розривів макули різного діаметра, однак відсутній єдиний підхід до вибору найбільш оптимальної техніки закриття розривів. Сьогодні доцільним є застосування фовеозберігаючих методик, які дають змогу уникнути певних морфологічних і функціональних змін, характерних для класичного пілінгу внутрішньої межової мембрани.

Authors: Pridavkova Zuzana , Furdová Alena , Kapitánová K. Benca , Vida Rastislav , Žiak P. , Popov I.
Published: March 2023

Introduction. Basal cell carcinoma is the most common tumour of the eyelids and periocular region throughout the world. BCC represents 90 % of malignant tumours of the eyelids, predominantly in the male population. The incidence is higher in age over 60. Over 50% of BCC of the periocular region initially occur on the lower lid and inner angle.
Research objectives. Literature review of the epidemiology, aetiopathogenesis, clinical attributes, diagnostics, treatment histopathology, recurrence, prognostic factors, and management of BCC.
Core of work. Standardised incidence of diagnosis C44 in the period 1997–2012 in Slovakia ranged from 35.05 to 73.9 cases per 100,000 inhabitants. The histopathological examination is essential. The first consideration for treatment of periocular BCC is radical surgical excision using Mohs micrographic technique. We can consider the apoptotic index, the expression of Bcl-2, as an unexplained prognostic factor of BCC recurrence.
Conclusion. Increased attention must be given to periocular malignant tumours. Functional and aesthetic outcome in patients is important after clear excisions and reconstruction should be carefully considered. Radical exenteration is considered in the case of orbital invasion of high-risk aggressive BCC.

Authors: Khatimah Khusnul , Pudjiati Sri Redatin Retno
Published: March 2023

The natural disaster occurred in PASIGALA in 2018 left a significant impact on the survivors of liquefaction. Research on recovery after a disaster focuses on the positive outcomes by survivors. This study aims to determine the role of trauma exposure and family hardiness in developing posttraumatic growth (PTG). Participants in this study were 147 adult survivors (Musia = 23.06, SD = 4.12) spread across Palu City and Sigi Regency, Central Sulawesi. PTG was measured by Posttraumatic Growth Inventory Short-Form (PTGI-SF), trauma exposure was measured by modification of the Earthquake Exposure Questionnaire and Impact of Event Scale, and family hardiness was measured by Family Hardiness Index (FHI). The hierarchical regression test found that trauma exposure and family hardiness significantly predicted 7% and 17.2% of posttraumatic growth variances when other variables were controlled. Then, the mediation test showed that family hardiness had a significant or partial role as a mediator between trauma exposure and PTG. The more trauma exposures experienced by individuals when natural disasters occurred, with a higher level of family hardiness, individuals would achieve a higher PTG condition (c = 0.759, p < 0.01) than if only considering the role of trauma exposure (c' = 0.301, p < 0.01). This shows that family hardiness is an important factor to consider when assisting liquefaction disaster survivors who are exposed to traumatic events in developing posttraumatic growth

Authors: Pikoli Megga Ratnasari
Published: March 2023

Scenedesmaceae is one of the microalgae groups that has been widely studied as promising biodiesel feedstock. Its morphological identification is often confused by environmental changes, so it requires molecular identification as well. The current study aimed to obtain primer pair candidates that identify the Scenedesmaceae based on the rbcL gene. The research used bioinformatics tools, which harvested rbcL protein sequence data, performed multiple sequence alignments, and designed primers based on conserved and less-conserved regions. The best left and right primers selected based on sequence length, melting temperature, 3' end stability, number of hairpins, and self-dimers, were paired, and three candidates were obtained. The three pairs were examined based on melting temperature difference, number of hetero-dimers, length of amplified nucleotide product, number of hits, and number of genera captured from the GenBank. Sce-16 (F, 5'-TGGTCGTGCTGTTTATGAATGT-3' and 1_RL, 5'-TGCCAAACATGAATACCACCA-3'), which is back-translated according to Hariotina sp. (AOY36008.1), is the most preferred candidate compared to the other two pairs after discussing their advantages and disadvantages. In the future, the proposed primer candidate needs to be validated through in vitro amplification with some optimizations to eliminate potential weaknesses.

The science of team science (SciTS): An emerging and evolving field of interdisciplinary collaboration
Authors: Huang Ying , Liu Xiaoting , Li Ruinan , Zhang Lin
Published: March 2023

In recent years, collaboration within a team to solve complicated scientific and social problems has attracted growing popularity. In particular, many complex challenges and opportunities require expertise and skills across disciplinary, organizational, and cultural boundaries. However, rapid growth in the demand for scientific collaboration has outpaced changes in the factors needed to support scientific teams. Also, scientific results are not simply a combination of different working results; understanding how teams work and what causes them to fail or succeed is of the utmost importance. Thus, the Science of Team Science (SciTS), an emerging interdisciplinary research area, has emerged as a way of understanding and managing the circumstances that facilitate or hinder the effectiveness of large-scale cross-disciplinary, collaborative research, training, and translational initiatives. SciTS integrates various quantitative and qualitative research methods and is still advancing in its sophistication. Using bibliometric and information visualization methods, this paper clarifies the concepts and connotations of teams and team science. It sets out important events in the emergence and development of SciTS and summarizes the characteristics of the SciTS literature, identifying seven main research areas. The paper concludes with a discussion on the challenges facing the future advancement of SciTS and corresponding recommendations for breaking through these bottlenecks. Our goal is to deepen researchers’ understanding of SciTS and better inform the policies and practices that govern SciTS for more effective team science.
Evolution, trends and future of native media: From avant-garde to the epicenter of the communications ecosystem
Authors: López-García Xosé , Silva-Rodríguez Alba , Vázquez-Herrero Jorge
Published: March 2023

Over recent decades, digital native media have flourished as one of the most important communicative tools in the world, despite certain geographical disparities. Not only is this kind of media here to stay, but they have transitioned from being a feature of the avant-garde to occupying a central space in the digital ecosystem. Despite the diversity of models, difficulties in articulating business models that ensure sustainability, and their lack of financial muscle, native media have opened up renewed options for digital journalism in both the present and the future. By analyzing the current media landscape and a study of the main trends, carried out using a review of the published scientific literature and an analysis of cases from the last five years, this paper explores the horizons of the “new wave” of digital native media that will face the challenges of the second half of this third decade of the millennium. Of course, the future has not yet been written: digital media will have to build from the native space, observing emerging trends, modern technologies, and without giving up on providing quality digital journalism that is based in truthfulness, transparency, the involvement of users and the set of actions that serve the public interest.

Функція нирок у чоловіків із метаболічним синдромом
Authors: Luchytskyi V.Ye. , Luchytskyi Ye.V. , Zubkova H.A. , Rybal´chenko V.M. , Skladanna I.I.
Published: March 2023

Метаболічий синдром (МС) є одним із вагомих чинників розвитку цукрового діабету 2-го типу (ЦД2) в чоловіків. Поліфакторність патогенетичних механізмів, які лежать в основі формування МС та його подальшого прогресування і можливого розвитку ЦД2, є одним із вагомих механізмів, які сприяють порушенню функції нирок. Провідну роль у розвитку хронічної хвороби нирок у чоловіків із МС відіграють ступінь вираженості інсулінорезистентності (ІР), наявність ожиріння, функціональний стан сипмато-адреналової системи, артеріальна гіпертензія (АГ), рівні статевих гормонів і стан ліпідного метаболізму. Патологія нирок діагностується приблизно в 40% пацієнтів із ЦД2 та має вірогідно значущий вплив на розвиток і прогресування серцево-судинної патології. Останні захворювання є загальновизнаними факторами, котрі призводять до підвищення показника смертності серед чоловіків, хворих на ЦД2. Вважається, що одним зі спільних чинників розвитку МС, ЦД2 та хронічної хвороби нирок є вік. Однак, останній не є доведеним чинником розвитку однієї з основних складових МС — ожиріння. Немає сумнівів у тому, що ожиріння саме по собі впливає на ниркову функцію та ризик хронічної хвороби нирок (ХХН). Зв’язок між ожирінням та ХХН не завжди пояснюється взаємозв’язком між ожирінням та ЦД2 або АГ відповідно. Ожиріння пов’язане з підвищеною швидкістю клубочкової фільтрації та нирковим кровотоком, а також із розвитком вогнищевого сегментарного гломерулосклерозу. У патогенезі розвитку ниркової патології при МС характерним є те, що ІР пов’язана з підвищеною тубулярною реабсорбцією натрію. Цей огляд присвячено епідеміології та механізмам, пов’язаним із пошкодженням судин нирок. Однак слід пам’ятати, що профілактика та лікування ниркового захворювання потребує багатофакторного підходу. Хронічна хвороба нирок у чоловіків, хворих на ЦД2 і МС потребує мультидисциплінарного підходу із залученням фахівців різних спеціальностей (окрім профільних ендокринолога та нефролога) з метою профілактики формування ниркової патології на ранніх етапах розвитку основного захворювання.
