Published: December 2024

The patchouli plant (Pogostemon cablin Benth.) is a tropical herbaceous plant that produces essential oil. One of the problems is that the production is not yet optimal. Fulfillment of superior seedlings can help increase patchouli productivity. Conventional patchouli propagation through stem cuttings is ineffective and takes longer. Patchouli propagation can be done using a tissue culture approach via direct organogenesis to produce seedlings quickly and efficiently. Effective patchouli propagation methods and successful acclimatization are very important to research to support the propagation and breeding of patchouli plants. The aim of this research was to determine the best of BAP concentration in direct organogenesis of leaf and stem explants. The research design used a completely randomized series of hormone BAP, it has 5 levels, namely 0 mg/L (as control), 0.25 mg/L, 0.50 mg/L, 0.75 mg/L, and 1.0 mg/L. The explants used were the leaves and stems of Aceh patchouli. Plantlets are acclimatized in compost media and covering treatment. Based on the results of observations, the best BAP concentration is 0.25 mg/L with the initial observation parameters of the early emergence of shoots, number of shoots, and length of shoots on leaf explants were 10 daps, 35.33 shoots, and 2.83 cm respectively. The use of leaf explants showed a better response compared to stem explants. Patchouli plantlets were successfully acclimatized and can adapt to the ex vitro environment using the covering method. Successful patchouli propagation and high acclimatization can help produce effective patchouli seeds.

Published: December 2024

Malaysia’s diverse population has influenced people’s lives in many areas, from fashion and cuisine to art and interpersonal relationships. The country’s diverse atmosphere has shaped the perspectives of young artists from different ethnic backgrounds, affecting their artistic expression and their ability to incorporate multicultural themes in their works. This study aims to find out how multiculturalism is perceived by young Malaysian artists from the country’s major ethnic groups - Malays, Chinese and Indians - and the feelings they express in their artworks. This study adds to the body of knowledge on multiculturalism from the perspective of young Malaysian artists by examining their visual perceptions. The study examines the works of these artists through a formal and contextual analysis. While the contextual analysis explores themes such as people, architecture and cuisine, the formal analysis focuses on visual components such as line, colour, texture and composition. The integration of these approaches helps to identify the preferences of the participants (the artists who created these paintings) and the cultural elements that appear in their works. The results of this study have shown that young Malaysian artists have frequently used symbolic colours to represent the different ethnic groups in Malaysia, along with repetitive motifs that show the connection and unity between different cultural elements. These findings show a new generation’s perspective on multiculturalism and provide an insight into the way young Malaysian artists perceive and communicate the complexity of diversity and how it manifests itself in the visual arts. These artworks show the harmony between diversity and unity and the influence of Malaysia’s multicultural society on the artistic output of the country’s youth.
Psychotherapy in one approach of resilience (PAR) - report of partial results in clinical psychology
Authors: Barbosa George Souza
Published: December 2024

Psychotherapy in one Approach of Resilience (PAR) is a structured methodology aimed at fostering resilience through the restructuring of beliefs. This study presents partial results of interventions conducted between 2021 and 2023, utilizing a protocol based on cognitive models of determinant beliefs (BMDs). The main objective was to analyze the effectiveness of PAR in developing resilience among participants by evaluating changes in beliefs and behaviors.

Methodology involved 12 weeks of psychotherapeutic interventions with nine participants, using instruments such as BAI, OQ-45.2, BDI-II, and the QUEST_Resiliencia scale. Data on keywords, belief changes, and behavioral shifts were collected and analyzed longitudinally.

Results demonstrated significant progress in mental flexibility and belief redefinition related to resilience, particularly in the domains of context analysis and self-confidence. However, areas such as conscious stress reactions showed limited improvement, suggesting resistance to change in bodily-related aspects.

It is concluded that PAR is a promising approach for fostering resilience, offering relevant clinical benefits. Future studies with larger and more diverse samples are recommended to validate these findings.

Published: December 2024

Pulmonary arterial hypertension (PAH) is a long-term condition characterised by increased resistance to blood flow in the pulmonary circulation. The disease has a progressive course and is associated with a poor prognosis. Without treatment, PAH is associated with mortality in <3 years. Over the past decade, many advances have been made in revising the haemodynamic definition, clinical classification, risk calculation score, treatment options etc. Suggestions from the Sixth World Symposium on Pulmonary Hypertension were incorporated into a literature review that was included in the European Society of Cardiology/European Respiratory Society (ESC/ERS)’s most recent iteration of their guidelines in 2022. The traditional cut-off for pulmonary hypertension (PH), i.e., mean pulmonary artery pressure (mPAP) >25 mm Hg, has been challenged by observational cohort studies, which have shown poor outcomes for values of 21–24 mmHg; the new consensus is that PH is defined at mPAP >20 mm Hg. Although the gold standard for diagnosis and the major source of therapy guidance continues to be right cardiac catheterisation, echocardiography remains the initial test of choice. A multidisciplinary approach is highly recommended when treating PH patients and careful evaluation of patients will aid in proper diagnosis and prognosis. Pharmacotherapy for PAH has seen a paradigm shift with the successful use of newer agents in more extensive, longer and more inclusive trials driven by hard endpoints. Macitentan, selexipag and riociguat are three oral agents that have shown astounding success in PAH randomised studies in the past decade. Upfront combination therapy with two agents is now becoming the norm (following the AMBITION, OPTIMA and ITALY trials) and the momentum is shifting towards triple therapy as for essential hypertension. More recently, inhaled treprostinil was shown to improve exercise capacity in PH associated with interstitial lung disease in the phase III INCREASE study and has been granted regulatory approval for World Health Organization group 3 PH. A new class of drug, sotatercept (a tumour growth factor-β signalling inhibitor), has also been recently approved by the Food and Drugs Administration for management of PAH based on positive results from the phase III STELLAR study. Pulmonary artery denervation and balloon pulmonary angioplasty have emerged as viable alternatives in PH that are resistant to drug therapy. This article aims to summarise the key changes and recent advances in diagnosis and managing PH in general, with an emphasis on certain subgroups.

Published: December 2024

The results of the analysis of Kirovohrad region forest evaluation database and field observations of Black Locust (Robinia pseudoacacia L.) forest stands at the State Enterprise «Oleksandrivsky Forestry» are presented aimed to develop a method for determining the invasive activity and selection value of Black Locust.
The observations of the forest stands were carried out according to a set of indicators by generally accepted methods of forest mensuration with additional estimation of qualitative indicators. A comprehensive assessment of the forest stands was carried out according to the sum of points determined by the average values of quantitative and qualitative indicators. To determine the invasive activity of Black Locust, a method based on the number of viable self-seeding in the study plot was proposed.
The high growth intensity, productivity and selection value of Black Locust, as well as the suitability of the species for the creation of forest plantations and protective stands in certain forest site conditions in the south of the Right Bank Forest-Steppe have been demonstrated.
Two stands that meet the requirements for the plus stands were selected. Possibility of plus trees selection and forest seed base creation is proved.
Low invasive activity of Black Locust was noted on the territory of the vast majority of the observed stands. At the same time, medium invasive activity was detected in 42.8% of the areas adjacent to the studied stands, low – in 28.6%, very high – in 28.6%. The proposed methodical approach can be used to determine the invasive activity and selection value of the Black Locust stands. Such comprehensive approach will provide an objective answer to the question of expediency of this species using for afforestation in a certain region.
Доцільність впровадження у лісові насадження України інтродукованих деревних видів
Authors: Debryniuk Iurii , Lavnyy Vasyl , Myklush Stepan , Chihrak Taras
Published: December 2024

Інтродуковані деревні види широко розповсюджені у лісових насадженнях Східної і Західної Європи, в т.ч. і в Україні. Переважна більшість інтродуцентів є високопродуктивними і біотично стійкими, однак деякі з них можуть проявляти ознаки інвазійності. Тому потрібно брати до уваги, що інвазійні види є одним із п’яти ключових чинників, які руйнують природні екосистеми. Непродумане їх впровадження може призвести до витіснення аборигенних видів, деградації природних екосистем та їх поступового зникнення. Поряд з цим, якщо в умовах кліматичних змін місцеві деревні види втрачають стійкість і продуктивність, необхідно здійснювати пошуки для їхньої рівноцінної (або кращої) заміни з урахуванням потенційних ризиків і небезпек.
Зважаючи на біоекологічні особливості та досвід використання в Європі високопродуктивних інтродукованих деревних видів (модрин Кемпфера та широколускатої, псевдотсуги Мензіса, ялиці великої та ін.), вони можуть забезпечити високу продуктивність та екологічну стійкість українських лісів в умовах кліматичних змін. Ці інтродуценти можуть стати основними об’єктами для промислового вирощування деревини в умовах зміни клімату. Жоден з них не є інвазійним, оскільки дуже складно поновлюються природним шляхом, не розмножуються вегетативно і природно не заселяють нові території. Поширення цих та деяких інших інтродукованих видів можна легко контролювати шляхом зрубування насаджень за їхньою участю, після чого формуються сприятливі умови для відновлення корінного типу деревостану (дубового, букового, соснового, ялинового тощо). Запровадження плантаційного лісовирощування на принципах породозміни за участю швидкорослих інтродукованих видів забезпечить отримання значних обсягів деревини за відносно короткі терміни, тобто сприятиме інтенсифікації лісогосподарського виробництва.
У жодному з документів – «Рамковій конвенції про охорону та сталий розвиток Карпат», «Державній стратегії управління лісами України до 2035 року», «FSC національному стандарті системи ведення лісового господарства для України» та ін. не існує прямої заборони на використання інтродуцентів у лісових насадженнях. Повної заборони не існує навіть для культивування інвазійних видів, якщо їхній вплив на природні екосистеми можна контролювати та запровадити дієві заходи щодо пом’якшення їхнього негативного впливу.
Зміни у структурі лісового фонду ДП «Рахівське лісове дослідне господарство» з інтервалом у 70 років

Published: December 2024

За лісовпорядними матеріалами Рахівського лісгоспу 1951-52 рр. та ДП «Рахівське лісове дослідне господарство» станом на 01.01.2021 р. з’ясовано особливості польових і камеральних лісовпорядкувальних робіт, які визначені нормативними матеріалами відповідного періоду та проаналізовано зміни у розподілі вкритих лісовою рослинністю ділянок за деревними видами, класами бонітету та відносними повнотами, особливості вікових змін насаджень переважаючих деревних видів. 
Нормативні матеріали аналізованих періодів різняться підходами щодо виділення категорій лісів відповідно до виконання ними функцій, формування господарських частин і господарських секцій. Відмінними також є методичні засади обґрунтування обсягів заготівлі деревини під час проектування рубок головного користування та застосування способів рубок.
За аналізований проміжок часу у лісовому фонді підприємства збільшилась площа інтродукованих деревних видів та видове різноманіття як твердолистяних, так і м’яколистяних видів, що може бути зумовлено як господарськими заходами, так і змінами клімату.
Відзначено значне зменшення площі насаджень ялиці білої – з майже 400 до 61 га та збільшення більше, ніж на 1,4 тис га, площі букових насаджень, що, ймовірно, зумовлено характером лісогосподарських заходів, біоекологічними особливостями деревних видів та зміною клімату, а також передачею окремих ділянок новоутвореному природоохоронному об’єкту.
Відзначено збільшення площ продуктивних ялинових насаджень та підвищення середнього класу бонітету насаджень основних деревних видів. Середній клас бонітету ялинових насаджень підвищився з 1а,6 до 1b,8, ялицевих – з 1а,7 до 1а,,2, модринових – з 1а,0 до 1b,3, букових – з 1,9 до 1,2. Також збільшились середні запаси деревостанів. Зокрема, середні запаси ялинових насаджень збільшились на 15%, а букових – більше ніж у два рази. Поряд з цим, інтенсивне ведення лісового господарства в останні роки позначилось на зниженні середньої відносної повноти насаджень хвойних деревних видів.
Ведення лісового господарства в гірських лісах регіону, орієнтоване на виконання ними захисних і рекреаційно-оздоровчих функцій, позначилось на обсягах заготівлі деревини, які зменшено, порівняно з лісовпорядкуванням 50-их років минулого століття, більше ніж у чотири рази.

CURRENT TRENDS OF SURGICAL TREATMENT INTERVERTEBRAL HERNIAS AND LUMBAR STENOSIS THE SPINE
Authors: Barkov Oleksandr
Published: December 2024

Objective. On the basis of a study of scientific literature on the treatment of patients with intercho-ribbus hernias and stenosis of the spinal canal of the lumbar spine to determine the tendencies of development of methods of performing surgical treatment of these diseases and the conditions of their appointment. Methods. The literature search was performed in the PubMed database. The inclusion criteria were original clinical studies in English. Results. We selected and studied 47 studies. Conclusions. The advantages of modern endoscopic spine surgery include less tissue damage, lower blood loss, less damage to the epidural blood supply with less fibrosis, shorter hospital stay, and early cosmetic recovery. Percutaneous endoscopic partial discectomy (PEPD) allows to avoid significant damage to the skin, muscles, plates and synapses, excessive load on the dura mater, it is performed under local anesthesia. This type of discectomy is more suitable for the treatment of foraminal and extraforaminal hernias, when the transforaminal approach facilitates visualization of the lesion. In the middle type hernias, the limitations of the intervertebral opening and the interference of the solid meninge when performing this technique leads to the worst clinical results. In general, after PEPD, the results are better than after microdiscectomy. Surgical treatment of lumbar spinal stenosis is mainly performed using single-channel endoscopic surgery, which allows for complete preservation of the physiological structure of the lumbar spine with minor surgical trauma and rapid postoperative recovery. The disadvantages are a small field, as well as the difficulty of expanding the boundaries of decompression. One of the most recent developments in the treatment of intervertebral hernias is unilateral biportal endoscopic discectomy (UBED). The effectiveness of discectomy and release of nerve roots in the spinal canal is higher than that of percutaneous endoscopic interlaminar partial discectomy, but UBED is longer, with greater actual blood loss during surgery

Objective. To research biomechanical particularities of knee joint flexion defomation in rheumatoid arthritis patients. Methods. The work is based on the analysis of the preoperative examination of 23 patients with RA with multi-plane deformations of the lower limb, who were treated in our clinic in the period from 2021 to 2024. The average age of the examined patients was (49.14 ± 6.37) years old. The quantitative assessment of contractures and computed tomography (CT) of the knee were performed on the patients. Results. As can be seen from the obtained results, the stresses in the contact zone on the lateral condyle of the tibial plateau increase by 36.71 % in conditions of flexion contracture of the knee 30°, on the medial condyle of the tibial plateau — by 36.64 %. It was established that the load on the condyles of the tibial plateau increased by 12.8 % in forced passive flexion of the knee joint by 6°, as a result of passive extension by 3° — the load on the condyles of the tibial plateau increased by 95.2 %, which is a critical and can lead to the degradation of bone tissue in the contact area and increase the risks of secondary arthrosis. Conclusions. The simulated solid 3D-model of the knee joint was developed and demonstrates that in the knee joint flexion position of 30º, according to the radius of curvature of the mediaal and lateral condyle, the contact area on the medial condyle of the tibial plateau is 2 times larger than that on the lateral one and is shifted slightly backwards. The standing with one support under the weight of a body 60 kg (600 N) in conditions of flexion contracture in the knee joint in a position of 30°, there is an increase in contact stresses on the external condyle of the tibial plateau by 36.71 %, on the internal condyle — by 36.64 %, which contributes to the progression of the clinical picture of RA with an increase in the phenomena of osteoarthritis specifically in the back parts of the knee joint.
EXPERIMENTAL EVALUATION OF THE EFFECTIVENESS OF CO2 APPLICATION IN A CARRAGEENAN MODEL OF INFLAMMATION: NEW PERSPECTIVES IN THE TREATMENT OF OSTEOARTHRITIS
Authors: Shtroblia Viktor
Published: December 2024

Osteoarthritis (OA) is a chronic degenerative joint disease that leads to pain and limited mobility. Inflammation is a key pathogenetic factor in OA, which is accompanied by the activity of pro-inflammatory cytokines. One of the most promising methods of treating inflammation is carboxytherapy (CO2), which has low toxicity and physiological safety, but its interaction with other anti-inflammatory drugs is not well understood. Objective. To evaluate the anti-inflammatory effect of CO2 in animal models of carrageenan inflammation and to study its combined use with diclofenac and chondroitin. Methods. The study was conducted on 56 Wistar rats, which were randomly divided into 7 groups. Inflammation was modelled by injecting carrageenan into the limb of the animals. Prophylactic injections of anti-inflammatory drugs (diclofenac, chondroitin) were performed intraperitoneally and CO2 subcutaneously one hour later. The size of the edema was analysed 1, 2, 3 and 5 hours after the injection. The rectal temperature of the animals was also measured to determine the overall inflammation. Results. One hour after the administration of carrageenan, the volume of the limb in group VII decreased to (0.429 ± 0.020) ml (p < 0.001), and in group VI — to (0.441 ± 0.017) ml (p < 0.001). After 2 hours, the maximum decrease in limb edema was observed in group VII — (0.491 ± 0.017) ml (by 52 %, p < 0.001), and in group VI — (0.495 ± 0.012) ml (by 38 %, p < 0.001). After 5 hours, the size of the limb edema in group VI decreased to (0.559 ± 0.030) ml (by 51 %, p < 0.001), and in group VII — to (0.571 ± 0.016) ml (by 46 %, p < 0.001). Rectal temperature in group VI decreased to (37.7 ± 0.3) °C (by 1.5 °C, p < 0.001), and in group VII — to (38.3 ± 0.2) °C (by 0.9 °C, p < 0.001). Conclusions. Carboxytherapy has a pronounced anti-inflammatory effect, which is manifested in the reduction of edema and temperature, especially when combined with diclofenac or chondroitin. Further research may be aimed at studying the possible mechanisms of the positive effect of CO2, optimising therapeutic regimens and determining the long-term effects of carboxytherapy.

Authors: Vorontsov Petro , Maltseva Valentyna , Tuliakov Vladyslav
Published: December 2024

In orthopedic and trauma surgery, bone defects are an increasing clinical problem in daily practice. To fill them, many advantages have bone allografts (BA), namely a large stock of transplantation material. Purpose of the study: to evaluate changes in bone mineral density (BMD) of the femur of rats after filling a distal metaphyseal defect with an bone allograft in combination with the simultaneous administration of mesenchymal stromal cells (MSCs) or platelet-rich plasma (PRP) depending on age. Methods. The model of the hole defect in the metaphysis of the femur in rats (aged 3 and 12 months) investigated BMD in terms of filling BA, including, with the simultaneous administration of MSCs or PRP during surgery. Results. In rats with an unfilled defect — the immutability of BMD during the experiment. Compared with 3-month-old rats in 12-months-old rats with BA BMD was 1.11 times higher on the 14th day (p < 0.05), and on the 90th day it was 1.11 times lower (p < 0.05), on the 28th day it was not differed. In the 3-month-old rats with A and MSC showed a 1.20-fold lower BMD (p < 0.05) on the 28th day, and on the 90th day BMD did not differ compared to the group with BA. BMD in 12-monthold rats with BA and MSC did not differ from the group with BA. In in 12-month-old rats with BA and PRP BMD was 1.18 times (p < 0.05) higher on the 28th day and on the 90th day — 1.14 times (p < 0.05) compared to the BA group, and in 3-month-old rats did not differ for all terms. Conclusions. In the case of filling a bone defect with a bone alograft in 12-month-old rats, the increase of BMD of the femur is slower than in 3-month-old rats. The use of BA with MSCs in younger rats causes a delay in bone regeneration on the 28th day, but does not disrupt this process, according to BMD on 90th day compared to rats with BA, and in older rats does not significantly change BMD during the study. Filling defect BA with PRP promotes the growth of femoral BMD in older rats from the 28th d ay, b ut i n y ounger r ats it d oes n ot c ause significant changes compared to the group with BA.

Published: December 2024

Fractures of the femoral head are often associated with hip dislocation. A high percentage of unsatisfactory functional treatment outcomes and complications (such as aseptic necrosis, heterotopic ossification, osteoarthritis, etc.) remains a challenge. Objective. To analyze the available information on the treatment approaches for femoral head fractures associated with hip dislocation using the Pipkin classification. Methods. A search of modern literature sources was conducted in the PubMed and Scopus databases using the following keywords: fracture, femoral head, Pipkin, hip joint, diagnosis, treatment, osteosynthesis. Results. The Pipkin classification enables the systematization of treatment approaches for patients and, when applied correctly, reduces the rate of complications and improves functional outcomes. Computed tomography is an essential procedure in diagnosing femoral head fractures associated with hip dislocation to facilitate the prompt reduction of the dislocation. The specific features of blood supply and the risks of aseptic necrosis formation, considered in the Pipkin classification, influence the treatment strategy, along with the type of fracture. For type I fractures, both conservative and surgical methods are possible. For type II fractures, screw fixation is preferred: using hidden compression screws, self-compressing headless screws, or bioresorbable screws. For type III fractures, urgent surgery is required, typically open reduction with primary endoprosthesis replacement. For type IV fractures, if the fracture type permits, open reduction and osteosynthesis are recommended. In postoperative care, early functional treatment is critical, with partial weight-bearing for 6–12 weeks, and avoiding excessive flexion of the hip beyond 45°–50°. Conclusions. A properly selected treatment strategy during the initial admission can reduce recovery times and improve treatment outcomes.

Published: December 2024

The increase in the number of primary arthroplasty procedures has led to an increase in revision arthroplasty for periprosthetic infection and fractures of hip stems. The problem of removing stable stems remains relevant, as the lack of a unified approach leads to an increase in the duration of operations, an increased risk of complications and worsening of treatment outcomes. Objective. To review the existing methods and find out the most optimal approaches to the removal of stable stems of hip arthroplasties of different types of fixation. Methods. A systematic literature review was conducted using the electronic databases PubMed, Scopus, Web of Science for the period 1986–2023. 28 publications were analyzed. The authors’ own clinical experience was used (171 revision interventions from 2013 to 2024). Results. The method of removal depends on the type of fixation and design of the endoprosthesis stem. The main methods are: use of special instruments, window osteotomy, extended proximal osteotomy, transfemoral osteotomy. The choice of method depends on the specific situation, starting with the least traumatic approach. Conclusions. Removal of stable stems requires an individual approach and careful planning. Cemented polished stems are usually easier to remove, but there may be difficulties with the removal of the cement mantle. Cementless stems with distal fixation often require more aggressive methods. The choice of method should be based on the principle of minimal trauma, taking into account the possibility of further revision arthroplasty. It is recommended to have several alternative surgical plans. The proposed methodology of intraoperative actions allows optimizing the decision-making process, which contributes to improving the results of revision hip arthroplasty.

Published: December 2024

Introdução: O câncer é a primeira causa de morte por doença na população infantojuvenil no Brasil. Sendo assim, percebe-se a relevância do cuidado paliativo, visto que trata-se de uma abordagem que aprimora a qualidade de vida de pacientes que enfrentam doenças oncológicas. Objetivos: investigar a relevância da assistência de enfermagem ao paciente onco pediátrico em cuidados paliativos. Metodologia: trata-se de uma revisão narrativa da literatura. Os descritores usados nas buscas foram “Oncologia”,“Pediatria”,“Cuidados Paliativos” e “Enfermagem”. Resultados: o cuidado com crianças oncológicas demanda abordagens específicas, diferentes das aplicadas a adultos, considerando aspectos emocionais e físicos, como dor, ansiedade e medo. A enfermagem tem um papel crucial, devido ao contato contínuo com o paciente, promovendo cuidados técnicos e humanizados. A Sistematização da Assistência de Enfermagem é essencial para melhorar a qualidade do atendimento, criando intervenções adaptadas às necessidades do paciente pediátrico. Ademais, as intervenções assistenciais devem focar também na prevenção de efeitos adversos da terapia, promovendo hábitos saudáveis. Incluir a família no processo de cuidado é fundamental, oferecendo suporte emocional e comunicando de maneira adequada sobre o tratamento. É vital que os enfermeiros saibam lidar com a comunicação de más notícias e apoiem a família, assegurando uma assistência digna e humanizada. Conclusão: a progressão de neoplasia incurável em crianças causa profundo sofrimento, exigindo que enfermeiros usem metodologias diversas, como Práticas Integrativas e Complementares e outras tecnologias leves para apoio o biopsicossocial. Capacitação adequada em cuidados paliativos, tanto durante a graduação quanto através de educação permanente, é essencial para uma assistência integral e humanizada.

Published: December 2024

As competências de consciência fonológica devem ser desenvolvidas o mais precocemente possível, na medida em que, a partir destas, desenvolve-se a capacidade de decodificação de sons e letras, possibilitando um posterior acesso ao princípio alfabético. No entanto, no caso de crianças com perda auditiva, verifica-se uma escassez de estudos que permitam aferir a eficácia de práticas baseadas em evidências, na melhoria do processamento fonológico destas crianças. Assim, foi realizada uma revisão sistemática da literatura tendo em conta os estudos de intervenções que tenham como foco o desenvolvimento de competências fonológicas em crianças com perda auditiva. Os procedimentos de síntese e relato da pesquisa adotados seguiram as diretrizes do PRISMA. Esta revisão incorpora treze estudos publicados em revistas especializadas nas últimas duas décadas, envolvendo um total de 268 crianças com perda auditiva, com idades compreendidas entre os 57 meses e os 15 anos, de nove nacionalidades, sendo Israel e Estados Unidos os países mais representativos. Em termos de duração, as intervenções variaram entre as seis e as trinta e seis semanas, com uma frequência que variou entre as duas e as quatro sessões semanais, perfazendo, em média, 30 horas de intervenção. No que concerne ao uso de meios auxiliares de audição, a maioria das crianças usava dispositivos de amplificação tradicionais. As intervenções revisadas no presente estudo reportaram, sem exceção, melhorias significativas nas competências fonológicas das crianças com surdez que nelas participaram, ao nível do fonema, da sílaba e da rima, o que reforça a premência de uma abordagem destas competências tão precocemente quanto possível, de modo a assegurar o acesso à língua, nas suas vertentes oral e escrita, tendo em conta a educação bilingue. As limitações enfrentadas por alguns estudos durante suas intervenções devem ser vistas como uma melhoria para pesquisas futuras.
Sentido de vida, bem-estar psicológico e saúde mental em adultos brasileiros
Authors: Veras Juliana , Vale Dias Maria da Luz
Published: December 2024

Atualmente, considera-se o sentido de vida como impulsionador do bem-estar psicológico e expressivamente relevante para a saúde mental. Esta abordagem psicológica positiva tem consciencializado cada vez mais a sociedade e a comunidade académica da necessidade de uma avaliação e investigação destes conceitos, de modo a entender as suas implicações. Este estudo contempla uma amostra de 431 sujeitos residentes na República Federativa do Brasil, 100 do sexo masculino e 331 do sexo feminino. Recorrendo a medidas de autorrelato, através da aplicação de questionários, a nossa pesquisa correlacionou os conceitos de sentido de vida, bem-estar psicológico e saúde mental, considerando ainda o género, idade e características de personalidade. Através da análise dos dados, conseguimos perceber que a procura do sentido de vida continua a ser predominante nos sujeitos, ainda que, numa amostra significativa, encontremos a afirmação de que já existe um propósito claro de vida. Quanto ao bem-estar psicológico, existem correlações positivas entre os seus fatores e a presença de sentido de vida, sendo que se relaciona negativamente com os sintomas de depressão, ansiedade e stresse. Quanto aos efeitos do sentido de vida e da personalidade na sintomatologia da saúde mental e no bem-estar psicológico, foi possível identificar interessantes preditores. Um outro dado relevante são as diferenças estatisticamente significativas entre adultos emergentes e adultos de meia-idade a nível das variáveis analisadas, não se registando um importante efeito do género. Concluímos que existem evidências de que continua a existir uma busca pelo sentido de vida e de que o bem-estar e a saúde mental são por ele afetados, deste modo, cabendo-nos uma análise das causas e de como estas têm implicações no dia-a-dia dos cidadãos brasileiros. Esta problemática surge como um alerta num tempo tão controverso, o pós-covid e com a atual ocorrência de conflitos bélicos internacionais.

Published: December 2024

A esperança é uma dimensão fundamental da experiência humana, influenciando não apenas a qualidade de vida de pacientes, mas também a resiliência perante desafios e adversidades. Na prática de enfermagem, a gestão da esperança emerge como um aspeto crucial na prestação de cuidados, especialmente em contexto de cuidados paliativos, onde a complexidade do processo de transição da pessoa e da sua família exige uma abordagem holística e sensível. Este trabalho pretendeu identificar desafios, estratégias e intervenções na prática de enfermagem na gestão da esperança em cuidados paliativos. Realizou-se um estudo qualitativo através de uma revisão narrativa, procurando publicações sobre o tema, em artigos publicados depois de 2010. Dada a escassez de discussões sobre o tema, este estudo procurou, principalmente, explorar tematicamente e problematizar lacunas no conhecimento científico. A análise de 9 artigos e 1 tese permitiu identificar desafios, estratégias e intervenções de enfermagem na gestão da esperança. A esperança constitui um processo dinâmico com objetivos realistas ajustados ao contexto e vivência da pessoa em situação de cuidados paliativos e sua família. A gestão da esperança constitui um foco de atenção na prática de enfermagem, baseada no reconhecimento das vivências, potencialidades e suporte social da pessoa e sua família, sendo concretizada através de estratégias promotoras de esperança. Os profissionais de enfermagem utilizam um conjunto de estratégias específicas para promover e manter a esperança na pessoa em situação paliativa e sua família. Estas estratégias incluem desde a adoção de uma comunicação empática e acolhedora até à prestação de suporte emocional e espiritual adequado às necessidades individuais da pessoa e de seus familiares. Esta abordagem global tem como objetivo não só mitigar o sofrimento físico, mas também proporcionar conforto psicológico e espiritual ao longo do processo de cuidados paliativos, evidenciando a importância da integralidade no cuidado à pessoa em situação de cuidados paliativos.

La Psicología Positiva, es la ciencia de las fortalezas humanas (Seligman, 1999), su concepción y objetivo engloba caracteres quevan mucho másallá del mero aspecto positivo dela persona, incidiendo también en lograr el éxito en la cara negativa de las vidas que les rodean (Seligman, 2005). En la esfera educativa, la psicología positiva centra su atención en las fortalezas, virtudes y cualidades específicas positivas de los estudiantes y grupos de estudiantes en ambientes pedagógicos (Hughes, 2000). Por ello, Seligman & Csikszentmihalyi (2000) promueven desarrollar competencias en los niños, fortaleciendo sus cualidades personales, ayudándoles a identificarlas y encontrar los espacios adecuados en los que poder expresarlas. El uso problemático y disfuncional de la Tecnología, es un problema creciente que interfiere en la vida familiar y académica de los adolescentes, con graves consecuencias y que se ha visto acrecentado por la crisis sanitaria emergente y el confinamiento derivado de la Covid-19. En este trabajo se revisan algunos estudios realizados en los últimos siete años en dichas áreas, destacando las variables personales que inciden y convergen en una relación sana de los jóvenes en el uso que realizan de las tecnologías.

Published: December 2024

Durante la pandemia, las medidas de distanciamiento social afectaron las relaciones personales y las plataformas digitales se consolidaron, lo que podría haber generado un posible aumento en las experiencias de sexting en ciertos sectores. Este estudio tuvo como objetivo analizar los cambios en la frecuencia del sexting durante el confinamiento por COVID-19 en jóvenes mexicanos, así como identificar diferencias según sexo, edad y experiencia sexual. Se contó con la participación de 1423 jóvenes de diez estados de la República Mexicana, de los cuales 1142 habían tenido experiencias de sexting. La edad promedio de estos jóvenes fue de 20.49 años, y cerca de la mitad de ellos fueron mujeres. Dadas las medidas sanitarias, la aplicación de los cuestionarios se llevó a cabo mediante una plataforma en línea y se diseminó con el apoyo de un panel de encuestas. Los resultados mostraron un incremento en las prácticas de sexting, principalmente entre la población más joven, sin experiencia sexual y en los hombres, aunque los efectos fueron moderados. Los hallazgos se discuten en virtud de las formas en que se ha evaluado el comportamiento de sexting, así como las medidas adoptadas en México durante la pandemia.
Estudio multivariado de los factores sociodemográficos que influyen en la cualificación de agentes educativos de primera infancia en Colombia
Authors: Adames Papa Fabian , Cuervo Leidy Carolina
Published: December 2024

Este estudio se centra en analizar los perfiles de quienes se encargan de la formación en la primera infancia y su influencia en los procesos de cualificación, con el propósito de ampliar la comprensión sobre las condiciones laborales y formativas de los agentes educativos (AE) en el ámbito de la educación infantil. El trabajo se enmarca dentro de un enfoque educativo inclusivo, orientado a la formación inicial de futuras generaciones de AE. Para ello,se adoptó una metodología cuantitativa que involucró a 1592 AE,con el fin de identificar los perfiles que interactúan de forma directa e indirecta con la primera infancia (PI) y su relación con los procesos de cualificación, utilizando un modelo Logit multivariado. Los hallazgos indican que los AE menores de 27 años, con al menos tres años de experiencia en educación infantil y que trabajan directamente con niños y niñas de PI, presentan una mayor probabilidad de cualificarse en este campo. No obstante, se observa una limitada participación en procesos de formación virtual, lo que evidencia una baja utilización de las herramientas tecnológicas asociadas a las TIC por parte de los AE. En el caso colombiano, es fundamental comprender las concepciones, prácticas y roles que estos agentes desempeñan como reguladores, orientadores y promotores del desarrollo adecuado de los niñosy niñas, quienes deben ser reconocidoscomo sujetos de derecho. En este contexto,se destaca la importancia de implementar estrategias que impulsen una mayor participación de los AE en formación virtual, maximizando así el uso de las TIC en la educación infantil.
