RESUMO

Plants have evolved intricate signaling pathways, which operate as networks governed by feedback to deal with stressors. Nevertheless, the sophisticated molecular mechanisms underlying these routes still need to be comprehended, and experimental validation poses significant challenges and expenses. Consequently, computational hypothesis evaluation gains prominence in understanding plant signaling dynamics. Biosensors are genetically modified to emit light when exposed to a particular hormone, such as abscisic acid (ABA), enabling quantification. We developed computational models to simulate the relationship between ABA concentrations and bioluminescent sensors utilizing the Hill equation and ordinary differential equations (ODEs), aiding better hypothesis development regarding plant signaling. Based on simulation results, the luminescence intensity was recorded for a concentration of 47.646 RLUs for 1.5 µmol, given the specified parameters and model assumptions. This method enhances our understanding of plant signaling pathways at the cellular level, offering significant benefits to the scientific community in a cost-effective manner. The alignment of these computational predictions with experimental results emphasizes the robustness of our approach, providing a cost-effective means to validate mathematical models empirically. The research intended to correlate the bioluminescence of biosensors with plant signaling and its mathematical models for quantified detection of specific plant hormone ABA.

RESUMO

Maize is a crucial staple crop that ensures global food security by supplying essential nutrients. However, heavy metal (HM) contamination inhibits maize growth, reduces output, and affects food security. Some endophytic fungi (EFs) in maize seeds have the potential to enhance growth and increase dry biomass, offering a solution to mitigate the negative effect of HM contamination. Using these functional EFs could help maintain crop production and ensure food safety in HM-contaminated areas. In the present study, the diversity of EFs in corn grains from various HM-contaminated areas in China was studied through culture-dependent and culture-independent methods. We tested the plant growth-promoting (PGP) traits of several dominant culturable isolates and evaluated the growth-promoting effects of these twenty-one isolates through pot experiments. Both studies showed that HM contamination increased the diversity and richness of corn grain EFs and affected the most dominant endophytes. Nigrospora and Fusarium were the most prevalent culturable endophytes in HM-contaminated areas. Conversely, Cladosporium spp. were the most isolated endophytes in non-contaminated areas. Different from this, Saccharomycopsis and Fusarium were the dominant EFs in HM-contaminated sites, while Neofusicoccum and Sarocladium were dominant in non-contaminated sites, according to a culture-independent analysis. PGP trait tests indicated that 70% of the tested isolates (forty-two) exhibited phosphorus solubilization, IAA production, or siderophore production activity. Specifically, 90% of the tested isolates from HM-contaminated sites showed better PGP results than 45% of the isolates from non-contaminated sites. The benefit of the twenty-one isolates on host plant growth was further studied through pot experiments, which showed that all the isolates could improve host plant growth. Among them, strains derived from HM-contaminated sites, including AK18 (Nigrospora), AK32 (Beauveria), SD93 (Gibberellia), and SD64 (Fusarium), had notable effects on enhancing the dry biomass of shoots and roots of maize under Cd stress. We speculate that the higher ratio of PGP EFs in corn grains from HM-contaminated areas may explain their competitiveness in such extreme environments. Fusarium and Cladosporium isolates show high PGP properties, but they can also be phytopathogenic. Therefore, it is essential to evaluate their pathogenic properties and safety for crops before considering their practical use in agriculture.

RESUMO

Background Childhood immunization programs in underdeveloped nations can improve children's growth and nutritional status and prevent growth delays while protecting against infectious diseases and meeting growth norms. This study aimed to assess the impact of vaccination status on the anthropometric indices of children aged 12-18 months at an Expanded Programme on Immunization vaccination center and compare the anthropometric indices of growth in children with complete and incomplete vaccination statuses. Methodology This study was conducted at the rural health center in Kala Shah Kaku, Pakistan, from November 2023 to December 2023. Children aged 12-18 months were enrolled and their vaccination status was recorded. Height and weight were measured using World Health Organization growth charts. The data were analyzed using descriptive statistics and chi-square and Fisher's exact tests. A p-value <0.05 was considered statistically significant. Results The mean age of the 110 children who visited the vaccination site for this study was 16.36 months ± 2.415. There were 28 (25.5%) stunted children. In the study, 17.6 (16%) participants were underweight, and 15.95 (14.5%) were wasted. Of the children, 79% had received all recommended vaccinations. A statistically significant (p < 0.05) association was found between vaccination and nutritional status. Conclusions This study emphasizes the significance of vaccination in promoting child health and nutrition, reducing stunting risk, and ensuring equitable access to vaccination services and comprehensive healthcare interventions. This can help mitigate the malnutrition burden and promote optimal growth, contributing to global health and development goals.

RESUMO

This study explored the neuroprotective potential of fermented pomegranate (PG-F) against hydrogen peroxide (H2O2)-induced neurotoxicity in human neuroblastoma SH-SY5Y cells and elucidated the underlying molecular mechanisms. The fermentation process, involving probiotics, transforms the hydrolyzable tannins in pomegranate juice into ellagic acid (EA) and gallic acid (GA), which are believed to contribute to its health benefits. Molecular docking simulations confirmed the stable interactions between EA, GA, and proteins associated with the antioxidant and anti-apoptotic pathways. PG-F significantly enhanced the viability of H2O2-treated cells, as evidenced by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays, cell morphology observations, and Hoechst 33342 staining. PG-F mitigated the H2O2-induced intracellular reactive oxygen species (ROS) levels, restored mitochondrial membrane potential, and upregulated antioxidant gene expression. The PG-F treatment also attenuated the H2O2-induced imbalance in the Bax/Bcl-2 ratio and reduced the cleaved caspase-3, caspase-7, and caspase-9 levels, suppressing the apoptotic pathways. Further insights showed that PG-F inhibited the phosphorylation of mitogen-activated protein kinases (MAPKs) and facilitated the nuclear translocation of nuclear factor-erythroid 2-related factor (Nrf2), highlighting its role in modulating the key signaling pathways. A combined treatment with equivalent concentrations of EA and GA, as found in PG-F, induced remarkable cellular protection. Drug combination analysis using the Chou-Talalay method revealed a synergistic effect between EA and GA, emphasizing their combined efficacy. In conclusion, PG-F has significant neuroprotective effects against H2O2-induced neurotoxicity by modulating the antioxidant and anti-apoptotic pathways. The synergistic action of EA and GA suggests the therapeutic potential of PG-F in alleviating oxidative stress-associated neurodegenerative diseases.

RESUMO

OBJECTIVES: We are reporting a rare case series of 2 siblings and their mother with diabetes having a CFAP126 gene mutation. CASE PRESENTATION: Two female siblings, presented with incidental hyperglycemia at the ages of 16 and 13. They had a strong family history of diabetes on the maternal side. The systemic examination was unremarkable. Sibling 1 had HbA1C of 12.3 % with insulin and C-peptide levels of 6.6 IU/L and 1.8 ng/mL, respectively. Sibling 2 had an HbA1C of 12.6 %, an insulin level of 7.3 IU/L, and a C-peptide level of 2.02 ng/mL. Anti-GAD-65 and IA2 antibodies were negative. Mother also shared similar clinical processes and exhibited comparable biochemical changes related to glucose metabolism with elevated HbA1C levels and negative autoimmune markers (anti-GAD65 and IA2 antibodies). Whole exome sequencing (WES) turned out to be negative for MODY variants but revealed a rare heterozygous mutation in the CFAP126 gene (c.310A>T p. (Lys104*) in this family including both siblings and mother. The pathogenicity prediction tool MutationTaster® classified the mutation as disease causing. Oral glibenclamide remarkably reduced insulin requirements and improved HbA1C levels. CONCLUSIONS: This rare genetic mutation is likely associated with diabetes and possibly a novel marker for a yet to be identified type of diabetes, that is responsive to oral sulfonylureas. The influence of this gene on insulin secretion needs to be confirmed through future research.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver condition globally and the leading cause of liver-related death and morbidity. The goal of this study was to collect current data in order to calculate the pooled prevalence of NAFLD in Pakistan. We conducted a comprehensive literature search on four electronic databases until March 2024 to find studies on the prevalence of NAFLD in Pakistan. Pooled prevalence estimates of NAFLD were obtained using random-effects meta-analytic models. The chi-square test was used to account for study heterogeneity, whereas the I2 statistic was used to assess inconsistency. The data were stratified by the general population (average risk) and individuals with metabolic diseases (high risk). Two reviewers thoroughly and independently screened, reviewed, and assessed all studies. In total, 468 studies were reviewed, and 34 were included. The pooled NAFLD prevalence in the general population was 29.82% (95% CI 21.39-39.01%; prediction interval: 2.98-68.92%) based on 13 studies. In individuals with metabolic disorders, the prevalence of NAFLD in patients with diabetes, hypertension, and obesity, was 58.47% (95% CI 54.23-62.64%; prediction interval: 38.16-77.40%), 74.08% (95% CI 60.50-85.70%), and 47.43% (95% CI 30.49-64.66%), respectively. There was no evidence of publication bias, although a statistically significant level of heterogeneity was seen among the studies (I2 ranged from 57.5 to 98.69%). The findings of this study indicate a substantial prevalence of NAFLD in the population of Pakistan. The Pakistani government must formulate a comprehensive approach and plan aimed at augmenting awareness, control, prevention, and treatment of fatty liver disease.Prospero Registration no: CRD42022356607.

RESUMO

OBJECTIVE: To perform audit of imaging practice in different hospitals to assess their adherence to guidelines on optimizing computerized tomography of kidneys, ureter and bladder (CT KUB) technique in order to reduce unnecessary scan length. To assess improvement in adherence to guidelines after intervention, following education of the technologists. MATERIAL AND METHODS: There were 12 participant radiology departments in eight cities of Islamic Republic of Pakistan. Findings of first audit round were presented in respective departmental meetings and technologists were educated. Second round was performed after 12 weeks. Our target was to achieve 100% compliance to standards. Comparison of adherence to guidelines before and after intervention was done. Total number of axial slices of KUB CT scan, images above upper pole of highest kidney (overscan/unnecessary slices) and percentage of unnecessary images were recorded. To calculate statistical significance of difference, Fischer exact and Chi-square tests were applied. RESULTS: Percentage of patients with appropriate CT KUB technique according to RCR guidelines was far less in first round (0-64%). It significantly improved after educating the technologists (35.57- 90.90%). CONCLUSION: By following standard practice of CT KUB scan, significant radiation dose reduction is achievable without compromising diagnostic details. ADVANCES IN KNOWLEDGE: Standardization of CT KUB examination technique can valuably contribute to reduction in unessential radiation exposure.

RESUMO

Introduction Low birth weight (LBW) is a well-known contributing factor to neonatal health, emphasizing the importance of maternal health and socio-economic conditions. The birth weight of a newborn is a major public health problem, which is more common in low-middle-income countries (LMICs). Objective The objective of this study is to assess the association of different socio-economic and maternal factors with LBW babies in Lahore. Methods This case-control study was carried out at the Obstetrics and Gynecological Department in Mayo Hospital, Lahore, Pakistan from September 25, 2023 to December 31, 2023. A total of 186 mothers who delivered in the maternity ward, categorized into two groups (93 cases and 93 controls), were included and data was collected with the help of a self-administered structured tool. A chi-square test was used to identify maternal risk factors significant for LBW babies. The strength of association between maternal risk factors and LBW babies was presented using the odds ratio (OR) with the respective 95% confidence interval (CI). Results The study revealed that maternal anemia [OR: 3.378, 95% CI: 1.568, 7.275] and inadequate nutritional status [OR: 1.031, 95% CI: 0.014, 0.071] were more likely to cause delivery of LBW babies. Regarding socio-demographic factors, household income < 25000 [OR: 5.185, 95% CI: 2.770, 9.707] and illiterate mothers [OR: 3.325, 95% CI: 1.820, 6.074] were associated with increased likelihood of LBW babies. Maternal age < 20 had a strong association [OR: 10.920, 95% CI: 2.455,48.575] with delivery of LBW children.  Conclusion The study concludes that multiple risk factors including anemia, inadequate nutritional status, household income < 25000, illiterate mother, and maternal age < 20 are strongly associated with LBW babies. It is apparent that a multimodal strategy is necessary to reduce the risk of LBW babies.

RESUMO

To study the influence of an elbow inlet on the rotating stall characteristics of a waterjet propulsion pump (WJPP), a three-dimensional internal flow field in a WJPP under a straight-pipe inlet and elbow inlet is numerically simulated. By comparing the hydraulic performance of WJPP under the two inlet conditions, the internal relationship between the inlet mode and the flow pattern in the pump is clarified. Based on unsteady pressure fluctuation characteristics and wavelet analysis, the influence of the inlet mode on the rotating stall is revealed, and the stall transient propagation characteristics under critical stall conditions are analyzed. The disturbance effects of the inlet channel geometry disappear under low flow rate conditions, the main disturbance is induced by the high-speed countercurrent, and the flow pattern under the elbow inlet is better than that under the straight-pipe inlet. Under the straight-pipe inlet, the single-stall nucleus in the WJPP temporarily experiences a low-frequency and high-amplitude disturbance, which subsequently transforms into a mode of multi-stall nuclei with high-frequency circumferential disturbance. Under the elbow inlet, the rotating stall always maintains a mode of high-amplitude and low-frequency disturbance, which represents the transient characteristics of a single stall core propagating in the circumferential direction inside the channel. The results of this study have a reference value for structural design optimization in a WJPP.

RESUMO

AIM: This study aimed to assess the feasibility and effectiveness of the pectoral nerves (PECS) II block in facilitating cardiac implantable electronic device (CIED) insertion in a sample of 120 patients, with a focus on the percentage of cases completed without additional intraoperative local anesthesia. METHODS: PECS II blocks were performed on the left side using ultrasound guidance in all 120 patients. Feasibility was assessed by the proportion of cases completed without the need for extra intraoperative local anesthetic. Secondary outcomes included the amount of additional local anesthetic used, intraoperative opioid requirements, postoperative pain scores, time to first postoperative analgesia, analgesic consumption, patient satisfaction, and block-related complications. RESULTS: Of the 120 patients, 78 (65%) required additional intraoperative local anesthetic, with a median volume of 8.2 mL (range 3-13 mL). Fifteen patients (12.5%) needed intraoperative opioid supplementation. Nine patients (7.5%) required postoperative tramadol for pain relief. In total, 98 patients (81.7%) reported high satisfaction levels with the procedure. CONCLUSIONS: The PECS II block, when combined with supplementary local anesthetic, provided effective postoperative analgesia for at least 24 h in 120 patients undergoing CIED insertion. While it did not completely replace surgical anesthesia in most cases, the PECS II block significantly contributed to a smoother intraoperative experience for patients.

RESUMO

In the majority of existing multi-view clustering methods, the prerequisite is that the data have the correct cross-view correspondence. However, this strong assumption may not always hold in real-world applications, giving rise to the so-called View-shuffled Problem (VsP). To address this challenge, we propose a novel multi-view clustering method, namely View-shuffled Clustering via the Modified Hungarian Algorithm (VsC-mH). Specifically, we first establish the cross-view correspondence of the shuffled data utilizing strategies of the global alignment and modified Hungarian algorithm (mH) based intra-category alignment. Subsequently, we generate the partition of the aligned data employing matrix factorization. The fusion of these two processes facilitates the interaction of information, resulting in improved quality of both data alignment and partition. VsC-mH is capable of handling the data with alignment ratios ranging from 0 to 100%. Both experimental and theoretical evidence guarantees the convergence of the proposed optimization algorithm. Extensive experimental results obtained on six practical datasets demonstrate the effectiveness and merits of the proposed method.

RESUMO

This study, conducted in Pakistan, examines the perspectives of 1200 physicians across diverse specialties regarding Left Atrial Appendage Occlusion (LAAO) procedures for atrial fibrillation (AF) patients with chronic kidney disease (CKD). Using a random sampling approach, physicians participated in a survey that assessed their familiarity with LAAO, views on its effectiveness and safety, experience levels, and encountered challenges. The results unveil a spectrum of knowledge levels among physicians, reinforcing the need for tailored medical education and training programs. The majority of respondents were between 30 and 49 years old (59.8 %). A notable proportion, 33.3 %, had limited or no knowledge of LAAO, with 16.7 % having never heard of the procedure, and 16.7 % having limited knowledge but no experience. About 36.2 % of physicians believed LAAO was moderately to extremely effective in reducing stroke risk, with 23.3 % considering it very effective and 25.4 % believing it to be extremely effective. The most commonly cited clinical indications were a history of recurrent strokes despite anticoagulation (34.6 %) and a high CHA2DS2-VASc score (27.3 %). Renal considerations played a significant role, with 33.1 % considering LAAO for CKD stage 4 or 5 patients with elevated stroke risk. Patient preferences, such as a desire to avoid long-term anticoagulant use, were important for 28.7 % of physicians. Identified challenges encompass limited equipment access, training gaps, patient reluctance, and administrative complexities. Furthermore, the study underscores the pivotal role of shared decision-making in healthcare delivery. These findings lay essential groundwork for improving LAAO utilization and patient-centered care in Pakistan's healthcare system.

RESUMO

Rapid urbanization worldwide, poses numerous environmental challenges between escalating land use land cover (LULC) changes and groundwater quality dynamics. The main objective of this study was to investigate the dynamics of groundwater quality and LULC changes in Sargodha district, Punjab, Pakistan. Groundwater hydrochemistry reveals acceptable pH levels (<8) but total dissolved solids (TDS), electrical conductivity (EC) and HCO3- showed dynamic fluctuations by exceeding WHO limits. Piper diagrams, indicated dominance by magnesium and bicarbonate types, underscoring the influence of natural processes and anthropogenic activities. Major ion relationships in 2010, 2015, and 2021 showed a high correlation (R2 > 0.85) between Na+ and Cl-, suggesting salinization. whereas, the poor correlation (<0.17) between Ca2+ and HCO3- does not support calcite dissolution as the primary process affecting groundwater composition. The examination of nitrate contamination in groundwater across the years 2010, 2015, and 2021 was found to be high in the municipal sewage zone, suggesting a prevailing issue of nitrate contamination attributed to urban activities. The Nitrate Pollution Index (NPI) reveals a concerning trend, with a higher proportion of samples classified under moderate to high pollution categories in 2015 and 2021 compared to 2010. The qualitative assessment of nitrate concentration on spatiotemporal scale showed lower values in 2010 while a consistent rise from 2015 to 2021 in north-east and western parts of district. Likewise, NPI was high in the north-eastern and south-western regions in 2010, then reduced in subsequent years, which may be attributed to effective waste management practices and alterations in agricultural practices. The health risk assessment of 2010 indicated Total Health Hazard Quotient (THQ) within the standard limit, while in 2015 and 2021, elevated health risk was observed. This study emphasizes the need to use multiple approaches to groundwater management for sustainable land use planning and regulations that prioritize groundwater quality conservation.

RESUMO

Tinnitus is the perception of sounds like ringing or buzzing in the ears without any external source, varying in intensity and potentially becoming chronic. This study aims to enhance the understanding and treatment of tinnitus by analyzing a dataset related to tinnitus therapy, focusing on electroencephalography (EEG) signals from patients undergoing treatment. The objectives of the study include applying various preprocessing techniques to ensure data quality, such as noise elimination and standardization of sampling rates, and extracting essential features from EEG signals, including power spectral density and statistical measures. The novelty of this research lies in its innovative approach to representing different channels of EEG signals as new graph network representations without losing any information. This transformation allows for the use of Graph Neural Networks (GNNs), specifically Graph Convolutional Networks (GCNs) combined with Long Short-Term Memory (LSTM) networks, to model intricate relationships and temporal dependencies within the EEG data. This method enables a comprehensive analysis of the complex interactions between EEG channels. The study reports an impressive accuracy rate of 99.41%, demonstrating the potential of this novel approach. By integrating graph representation and deep learning, this research introduces a new methodology for analyzing tinnitus therapy data, aiming to contribute to more effective treatment strategies for tinnitus sufferers.

RESUMO

Machine learning has emerged as a leading field in artificial intelligence, demonstrating expert-level performance in various domains. Astronomy has benefited from machine learning techniques, particularly in classifying and identifying stars based on their features. This study focuses on the spectra-based classification of 11,408 B-type and 2422 hot subdwarf stars. The study employs baseline correction using Asymmetric Least Squares (ALS) to enhance classification accuracy. It applies the Pan-Core concept to identify 500 unique patterns or ranges for both types of stars. These patterns are the foundation for creating Support Vector Machine (SVM) models, including the linear (L-SVM), polynomial (P-SVM), and radial basis (R-SVM) kernels. Parameter tuning for the SVM models is achieved through cross-validation. Evaluation of the SVM models on test data reveals that the linear kernel SVM achieves the highest accuracy (87.0%), surpassing the polynomial kernel SVM (84.1%) and radial kernel SVM (80.1%). The average calibrated accuracy falls within the range of 90-95%. These results demonstrate the potential of using spectrum-based classification to aid astronomers in improving and expanding their understanding of stars, with a specific focus on the identification of hot subdwarf stars. This study presents a valuable investigation for astronomers, as it enables the classification of stars based on their spectra, leveraging machine learning techniques to enhance their knowledge and insights in astronomy.

RESUMO

Sustainable water management is essential to increasing water availability and decreasing water pollution. The wastewater sector is expanding globally and beginning to incorporate technologies that recover nutrients from wastewater. Nutrient recovery increases energy consumption but may reduce the demand for nutrients from virgin sources. We estimate the increase in annual global energy consumption (1,100 million GJ) and greenhouse gas emissions (84 million t CO2e) for wastewater treatment in the year 2030 compared to today's levels to meet sustainable development goals. To capture these trends, integrated assessment and computable general equilibrium models that address the energy-water nexus must evolve. We reviewed 16 of these models to assess how well they capture wastewater treatment plant energy consumption and GHG emissions. Only three models include biogas production from the wastewater organic content. Four explicitly represent energy demand for wastewater treatment, and eight include explicit representation of wastewater treatment plant greenhouse gas emissions. Of those eight models, six models quantify methane emissions from treatment, five include representation of emissions of nitrous oxide, and two include representation of emissions of carbon dioxide. Our review concludes with proposals to improve these models to better capture the energy-water nexus associated with the evolving wastewater treatment sector.

RESUMO

Postmenopausal osteoporosis, characterized by an imbalance between osteoclast-mediated bone resorption and osteoblast-driven bone formation, presents substantial health implications. In this study, we investigated the role of black goat extract (BGE), derived from a domesticated native Korean goat, estrogen-like activity, and osteoprotective effects in vitro. BGE's mineral and fatty acid compositions were analyzed via the ICP-AES method and gas chromatography-mass spectrometry, respectively. In vitro experiments were conducted using MCF-7 breast cancer cells, MC3T3-E1 osteoblasts, and RAW264.7 osteoclasts. BGE exhibits a favorable amount of mineral and fatty acid content. It displayed antimenopausal activity by stimulating MCF-7 cell proliferation and augmenting estrogen-related gene expression (ERα, ERß, and pS2). Moreover, BGE positively impacted osteogenesis and mineralization in MC3T3-E1 cells through Wnt/ß-catenin pathway modulation, leading to heightened expression of Runt-related transcription factor 2, osteoprotegerin, and collagen type 1. Significantly, BGE effectively suppressed osteoclastogenesis by curtailing osteoclast formation and activity in RAW264.7 cells, concurrently downregulating pivotal signaling molecules, including receptor activator of nuclear factor κ B and tumor necrosis factor receptor-associated factor 6. This study offers a shred of preliminary evidence for the prospective use of BGE as an effective postmenopausal osteoporosis treatment.

RESUMO

Objective.Brain-computer interfaces (BCI) have been extensively researched in controlled lab settings where the P300 event-related potential (ERP), elicited in the rapid serial visual presentation (RSVP) paradigm, has shown promising potential. However, deploying BCIs outside of laboratory settings is challenging due to the presence of contaminating artifacts that often occur as a result of activities such as talking, head movements, and body movements. These artifacts can severely contaminate the measured EEG signals and consequently impede detection of the P300 ERP. Our goal is to assess the impact of these real-world noise factors on the performance of a RSVP-BCI, specifically focusing on single-trial P300 detection.Approach.In this study, we examine the impact of movement activity on the performance of a P300-based RSVP-BCI application designed to allow users to search images at high speed. Using machine learning, we assessed P300 detection performance using both EEG data captured in optimal recording conditions (e.g. where participants were instructed to refrain from moving) and a variety of conditions where the participant intentionally produced movements to contaminate the EEG recording.Main results.The results, presented as area under the receiver operating characteristic curve (ROC-AUC) scores, provide insight into the significant impact of noise on single-trial P300 detection. Notably, there is a reduction in classifier detection accuracy when intentionally contaminated RSVP trials are used for training and testing, when compared to using non-intentionally contaminated RSVP trials.Significance.Our findings underscore the necessity of addressing and mitigating noise in EEG recordings to facilitate the use of BCIs in real-world settings, thus extending the reach of EEG technology beyond the confines of the laboratory.

RESUMO

Background: Aspergillus, a widespread fungus in the natural environment, poses a significant threat to human health by entering the human body via the airways and causing a disease called aspergillosis. This study comprehensively analyzed data on aspergillosis in published articles from mainland China to investigate the prevalence of Aspergillus, and risk factors, mortality rate, and underlying condition associated with aspergillosis. Methods: Published articles were retrieved from Google Scholar, PubMed, and Science Direct online search engines. In the 101 analyzed studies, 3558 Aspergillus isolates were meticulously collected and classified. GraphPad Prism 8 was used to statistically examine the epidemiology and clinical characteristics of aspergillosis. Results: Aspergillus fumigatus was prominently reported (n = 2679, 75.14%), followed by A. flavus (n = 437, 12.25%), A. niger (n = 219, 6.14%), and A. terreus (n = 119, 3.33%). Of a total of 9810 patients, 7513 probable cases accounted for the highest number, followed by confirmed cases (n = 1956) and possible cases (n = 341). In patients, cough emerged as the most common complaint (n = 1819, 18.54%), followed by asthma (n = 1029, 10.48%) and fever (1024, 10.44%). Of total studies, invasive pulmonary aspergillosis (IPA) was reported in 47 (45.53%) studies, exhibiting an increased prevalence in Beijing (n = 12, 25.53%), Guangdong (n = 7, 14.89%), and Shanghai (n = 6, 12.76%). Chronic pulmonary aspergillosis (CPA) was reported in 14 (13.86%) studies. Among the total of 14 studies, the occurrence of CPA was 5 (35.71%) in Beijing and 3 (21.42%) in Shanghai. Allergic bronchopulmonary aspergillosis (ABPA), was reported at a lower frequency (n = 8, 7.92%), Guangdong recorded a relatively high number (n = 3, 37.5%), followed by Beijing (n = 2, 25.0%), and Shanghai (n = 1, 12.5%). Percentage of death reported: IPA had the highest rate (n = 447, 68.87%), followed by CPA (n = 181, 27.88%) and ABPA (n = 14, 2.15%). Among the aspergillosis patients, 6220 had underlying conditions, including chronic lung disease (n = 3765, 60.53%), previous tuberculosis (n = 416, 6.68%), and organ transplant or organ failure (n = 648, 10.41%). Aspergillosis was also found in patients using corticosteroid therapy (n = 622, 10.0%). Conclusion: This review sheds light on the prevalence patterns of Aspergillus species, risk factors of aspergillosis, and gaps in surveillance that could be helpful for the control and treatment of aspergillosis and guide the researchers in future studies. Registration: This systematic review was prospectively registered on PROSPERO: Registration ID CRD42023476870.
