Authors: Хромуляк О. І. 
Published: February 2024

У Київському Поліссі однією з проблем лісовідновлення є потрава молодих рослин сосни звичайної дикими парнокопитними тваринами. Оцінено ефективність застосування репеленту «Цервакол Екстра» для захисту незімкнених культур сосни в ДП «Київська ЛНДС». На двох ділянках 30 ? 20 м окремо для кожної рослини дослідного й контрольного варіантів виявляли: наявність пошкодження лише верхівкового пагона, наявність пошкоджень верхівкового та бічних пагонів, відсутність пошкоджень. Також окомірно визначали частку пошкоджених пагонів кожної рослини – до 50 % та ? 50 %, а також частку рослин, які втратили спроможність до регенерації. Доведено, що у варіанті застосування репеленту «Цервакол Екстра» зменшується інтенсивність пошкодження пагонів сосни парнокопитними та частка рослин, що втратили спроможність до регенерації (p < 0,05). Частка рослин, пошкоджених парнокопитними у варіанті застосування репеленту, не перевищувала 6 %.

Викладено теоретичні й практичні підходи з виявлення можливостей для формування різновікових насаджень у підпорядкованому Держлісагентству лісовому фонді передгірної та гірської частин Закарпатської області. Визначено особливості утворення різновікових деревостанів із акцентуванням, передусім, на спроможності переважаючих у їхньому складі типоутворювальних порід забезпечувати різновіковість як таку. Підтверджено, що для формування різновікових насаджень у регіоні найбільш придатними є бук лісовий (Fagus sylvatica L.), ялина європейська (Picea abies (L.) Karst) та ялиця біла (Abies alba Mill.). Виявлено, що в лісостанах із цих порід ознаки різновіковості дерев починають виявлятися лише з настанням природної стиглості деревостанів, тобто в перестійних насадженнях. З огляду на це, зі встановленої площі перестійних насаджень, розподілених за типоутворювальними породами, режимoм лісокористування і належністю до відповідних категорій лісів, визначено частку площі деревостанів із бука, ялини та ялиці – порід, які біологічно спроможні утворювати різновікові насадження. Такі перестійні деревостани з бука, ялини та ялиці займають 40 519,8 га вкритих лісовою рослинністю земель аналізованого лісового фонду й відповідають ключовим ознакам різновікових насаджень.

За матеріалами лісовпорядкування досліджено стан і продуктивність соснових насаджень у рекреаційно-оздоровчих лісах Лівобережного Полісся залежно від їхнього розташування. Розраховано розподіл цих насаджень за походженням, типами лісу, групами віку, класами бонітету, відносними повнотами та класами віку. Виявлено, що соснові насадження в рекреаційно-оздоровчих лісах регіону ростуть на площі майже 47 тис. га. Більшість площ соснових насаджень (55,9 %) зосереджені в умовах свіжого дубово-соснового субору. Переважають середньовікові насадження як за площею (65,6 %), так і за запасом (70,9 %). Більшість сосняків ростуть за І класом бонітету та характеризуються відносною повнотою 0,7–0,8. Показник використання лісорослинного потенціалу модальними сосняками лісових ділянок зелених зон навколо населених пунктів становить 67 % і є порівняно невисоким, порівнюючи з місцевими високопродуктивними деревостанами.

During the development of natural gas hydrates, it is important to ensure the stability of the reservoir. The hydrate reservoirs in the South China Sea are clayey silt sediments, which are prone to sand production and collapse during hydrate dissociation. This study innovatively proposes the idea of consolidation-acidizing for NGH reservoir modification. Based on the core parameters of well A drilling in the Shenhu Sea area of the South China Sea, NGH sediment skeleton samples were artificially prepared. Core sensitivity testing indicates that the NGH reservoir has the potential for acidizing modification. After using tetraethyl orthosilicate to solidify the sample, it was found that Young’s modulus of the sample increased by 58.8%, and the compressive strength increased by 54.78%. Although the porosity decreased by 39.33%, the pores were not completely blocked. After the acidizing experiment, the permeability of the consolidated sample was 2.88 mD, and the porosity increased by 10.63%; The permeability of the unconsolidated sample was 1.86 mD, and the porosity decreased by 10.73%. The CT scan images also showed that the pores of the sample after consolidation-acidizing developed uniformly without significant deformation; The unconsolidated sample undergoes severe deformation and sand production after acidizing. This study demonstrates that the consolidation-acidizing modification method is feasible in clayey silt hydrate reservoirs.

Published: February 2024

IntroductionSince 2015, Colombia has faced a significant humanitarian challenge, receiving 2.9 million displaced Venezuelans. This study examines organizational cooperation in the humanitarian response to this migration crisis, aiming to understand the coordination dynamics among key organizations and actors.MethodsOur research combined interviews and web scraping to gather data on key actors and their relationships in the humanitarian response. We employed Social Network Analysis (SNA) to examine these relationships and the collaborative strategies among entities, focusing on how they address the migration challenges.ResultsThe results indicate that cooperation occurred through mediated channels, where established NGOs collaborated via coordination mechanisms established by international non-governmental organizations (INGOs), often involving diaspora volunteer-based organizations and through ad-hoc coordination. We also identified that organizations specializing in specific activities often exhibited limited coordination with others operating in the same sector. Lastly, the results suggest that coordination mechanisms played a crucial role in driving activities and facilitating the diversification of responses, partly through allocating financial resources.DiscussionThis study contributes to the humanitarian aid and migration literature, focusing on Colombia's migration response. It employs a mixed-methods approach, including Social Network Analysis (SNA), to explore the dynamics within humanitarian networks. It highlights the role of the Venezuelan diaspora NGOs, challenging the conventional view of migrants solely as aid recipients. The research uncovers the complex roles of intermediaries and coordination mechanisms, offering new insights into constructing effective humanitarian network structures. It advocates for a collaborative and inclusive approach to managing migration situations.

Published: February 2024

BackgroundThe aim of this study was to identify inflammatory biomarkers in traumatic proliferative vitreoretinopathy (TPVR) patients and further validate the expression curve of particular biomarkers in the rabbit TPVR model.MethodsThe Olink Inflammation Panel was used to compare the differentially expressed proteins (DEPs) in the vitreous of TPVR patients 7–14 days after open globe injury (OGI) (N = 19) and macular hole patients (N = 22), followed by correlation analysis between DEPs and clinical signs, protein–protein interaction (PPI) analysis, area under the receiver operating characteristic curve (AUC) analysis, and function enrichment analysis. A TPVR rabbit model was established and expression levels of candidate interleukin family members (IL-6, IL-7, and IL-33) were measured by enzyme-linked immunosorbent assay (ELISA) at 0, 1, 3, 7, 10, 14, and 28 days after OGI.ResultsForty-eight DEPs were detected between the two groups. Correlation analysis showed that CXCL5, EN-RAGE, IL-7, ADA, CD5, CCL25, CASP8, TWEAK, and IL-33 were significantly correlated with clinical signs including ocular wound characteristics, PVR scoring, PVR recurrence, and final visual acuity (R = 0.467–0.699, p &lt; 0.05), and all with optimal AUC values (0.7344–1). Correlations between DEP analysis and PPI analysis further verified that IL-6, IL-7, IL-8, IL-33, HGF, and CXCL5 were highly interactive (combined score: 0.669–0.983). These DEPs were enriched in novel pathways such as cancer signaling pathway (N = 14, p &lt; 0.000). Vitreous levels of IL-6, IL-7, and IL-33 in the rabbit TPVR model displayed consistency with the trend in Olink data, all exhibiting marked differential expression 1 day following the OGI.ConclusionIL-7, IL-33, EN-RAGE, TWEAK, CXCL5, and CD5 may be potential biomarkers for TPVR pathogenesis and prognosis, and early post-injury may be an ideal time for TPVR intervention targeting interleukin family biomarkers.

IntroductionBioelectrical impedance analysis (BIA) serves as a method to estimate body composition. Parameters such as phase angle (PA), standardized phase angle (SPA), body mass cell (BCM), BCM index (BCMI), and fat-free mass (FFM) might significantly impact the prognosis of head and neck cancer (HNC) patients. The present study aimed to investigate whether bioelectrical parameters can be used to predict survival in the HNC population and establish the optimal cutoff points for predictive accuracy.MethodsA multicenter observational study was performed across 12 tertiary hospitals in Andalusia (a region from the south of Spain). A total of 494 patients diagnosed with HNC between 2020 and 2022 at different stages were included in this study, with a minimum follow-up period of 12 months. The BIA assessment was carried out during the first 2 weeks of radical radiotherapy treatment with chemotherapy or other systemic treatments. A multivariate logistic regression analysis of overall survival, complications, hospital admission, and palliative care and its relationship with BIA nutritional assessment was performed.ResultsSignificant prognostic factors identified in the multivariable analysis encompassed phase angle (PA), standardized phase angle (SPA), body cell mass (BCM), and BCM index (BCMI). Lower PA and BCM values were significantly associated with adverse clinical outcomes. A BCM threshold above 17 kg/m2 was the most significant predictor for predicting survival within the overall HNC population. The PA values of &lt;5.1° in male and &lt;4.8° in female patients showed the best predictive potential for mortality. Increased PA (as a continuous variable) demonstrated a significantly reduced risk for mortality (OR, 0.64; 95% CI, 0.43–0.94; p &lt; 0.05) and a decreased likelihood of hospital admission (OR, 0.75; 95% CI, 0.52–1.07; p &lt; 0.05). Higher BCM correlated with a lower risk of mortality (OR, 0.88; 95% CI, 0.80–0.96; p &lt; 0.01) and a diminished probability of hospital admission (OR, 0.91; 95% CI, 0.83–0.99; p &lt; 0.05).ConclusionBIA is a crucial tool in the nutritional assessment of HNC patients. BCM and PA are the main bioelectrical parameters used to predict clinical outcomes in this population. Future studies are needed to validate BIA variables in a large cohort to ensure whether early intensification of nutritional treatment would improve survival.

IntroductionAvoiding over-investigation and overtreatment in health care is a challenge for clinicians across the world, prompting the international Choosing Wisely campaign. Lists of recommendations regarding medical overactivity are helpful tools to guide clinicians and quality improvement initiatives. We aimed to identify the most frequent and important clinical challenges related to pediatric medical overactivity in Europe and Japan. Based on the results, we aim to establish a (European) list of Choosing Wisely recommendations.MethodsIn an online survey, clinicians responsible for child health care in Europe and Japan were invited to rate 18 predefined examples of medical overactivity. This list was compiled by a specific strategic advisory group belonging to the European Academy of Paediatrics (EAP). Participants were asked to rate on a Likert scale (5 as the most frequent/important) according to how frequent these examples were in their working environment, and how important they were considered for change in practice.ResultsOf 2,716 physicians who completed the survey, 93% (n = 2,524) came from 17 countries, Japan (n = 549) being the largest contributor. Pediatricians or pediatric residents comprised 89%, and 51% had 10–30 years of clinical experience. Cough and cold medicines, and inhaled drugs in bronchiolitis were ranked as the most frequent (3.18 and 3.07 on the Likert scale, respectively), followed by intravenous antibiotics for a predefined duration (3.01), antibiotics in uncomplicated acute otitis media (2.96) and in well-appearing newborns. Regarding importance, the above-mentioned five topics in addition to two other examples of antibiotic overtreatment were among the top 10. Also, IgE tests for food allergies without relevant medical history and acid blockers for infant GER were ranked high.ConclusionOvertreatment with antibiotics together with cough/cold medicines and inhaled drugs in bronchiolitis were rated as the most frequent and important examples of overtreatment across countries in Europe and Japan.

IntroductionAnxiety and depression are among the common comorbidities of people diagnosed with cancer. However, despite the progress in therapeutic options and outcomes, mental health care and support have lagged behind for cancer patients. Estimating the extent and determinants of mental health disorders among cancer patients is crucial to alert concerned bodies for action. In view of this, we aimed to determine the pooled prevalence and determinants of anxiety and depression among cancer patients in Ethiopia.MethodsRelevant literatures were searched on PubMed, African Journals Online, Hinari, Epistemonikos, Scopus, EMBASE, CINAHL, Cochrane Library, and Gray literature sources. Data were extracted into an Excel spreadsheet and analyzed using STATA 17 statistical software. The random effect model was used to summarize the pooled effect sizes with their respective 95% confidence intervals. The I2 statistics and Egger’s regression test in conjunction with the funnel plot were utilized to evaluate heterogeneity and publication bias among included studies respectively.ResultsA total of 17 studies with 5,592 participants were considered in this review. The pooled prevalence of anxiety and depression among cancer patients in Ethiopia were 45.10% (95% CI: 36.74, 53.45) and 42.96% (95% CI: 34.98, 50.93), respectively. Primary and above education (OR= 0.76, 95% CI: 0.60, 0.97), poor social support (OR= 2.27, 95% CI: 1.29, 3.98), occupational status (OR= 0.59; 95% CI: 0.43, 0.82), advanced cancer stage (OR= 2.19, 95% CI: 1.38, 3.47), comorbid illness (OR= 1.67; 95% CI: 1.09, 2.58) and poor sleep quality (OR= 11.34, 95% CI: 6.47, 19.89) were significantly associated with depression. Whereas, advanced cancer stage (OR= 1.59, 95% CI: 1.15, 2.20) and poor sleep quality (OR= 12.56, 95% CI: 6.4 1, 24.62) were the factors associated with anxiety.ConclusionThis meta-analysis indicated that a substantial proportion of cancer patients suffer from anxiety and depression in Ethiopia. Educational status, occupational status, social support, cancer stage, comorbid illness and sleep quality were significantly associated with depression. Whereas, anxiety was predicted by cancer stage and sleep quality. Thus, the provision of comprehensive mental health support as a constituent of chronic cancer care is crucial to mitigate the impact and occurrence of anxiety and depression among cancer patients. Besides, families and the community should strengthen social support for cancer patients.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42023468621.

BackgroundMyopia poses a global health concern and is influenced by both genetic and environmental factors. The incidence of myopia tends to increase during infectious outbreaks, such as the COVID-19 pandemic. This study examined the screen-time behaviors among Chinese children and adolescents and investigated the efficacy of artificial intelligence (AI)-based alerts in modifying screen-time practices.MethodsA cross-sectional analysis was performed using data from 6,716 children and adolescents with AI-enhanced tablets that monitored and recorded their behavior and environmental light during screen time.ResultsThe median daily screen time of all participants was 58.82 min. Among all age groups, elementary-school students had the longest median daily screen time, which was 87.25 min and exceeded 4 h per week. Children younger than 2 years engaged with tablets for a median of 41.84 min per day. Learning accounted for 54.88% of participants’ screen time, and 51.03% (3,390/6,643) of the participants used tablets for 1 h at an average distance &lt;50 cm. The distance and posture alarms were triggered 807,355 and 509,199 times, respectively. In the study, 70.65% of the participants used the tablet under an illuminance of &lt;300 lux during the day and 61.11% under an illuminance of &lt;100 lux at night. The ambient light of 85.19% of the participants exceeded 4,000 K color temperature during night. Most incorrect viewing habits (65.49% in viewing distance; 86.48% in viewing posture) were rectified swiftly following AI notifications (all p &lt; 0.05).ConclusionYoung children are increasingly using digital screens, with school-age children and adolescents showing longer screen time than preschoolers. The study highlighted inadequate lighting conditions during screen use. AI alerts proved effective in prompting users to correct their screen-related behavior promptly.
