The assessment of the conservation status of species is crucial to effective conservation strategies, particularly in the current context of global changes. However, the quality of these assessments can be undermined by taxonomic uncertainties. One such case is the black maple whose conservation status is incongruent among Canadian provinces and American states where it naturally occurs. Morphological disparities between sugar maple and black maple led to their description as distinct species at the end of the 19th century, yet extensive hybridization between the two forms and low genetic differentiation has been reported since. The consensus on the taxonomical designation of black maple remains elusive and is sometimes recognised as a subspecies or ecotype of the sugar maple. To further investigate genetic distinctiveness of sugar and black maple, we analyzed high-throughput sequencing data obtained from two 700-meters apart stands within a contiguous forest where the two maples coexist. We sampled groups of individuals presenting the typical morphological characters of limb outlines and pubescence of each maple. Genetic data unveiled substantial differentiation between these two maples, confirming the distinctiveness of the black maple gene pools and justifying its recognition as a distinct species. Furthermore, black maple populations in Quebec exhibited markedly greater genetic structure and inbreeding compared to their sugar maple counterparts at equivalent latitudes. These findings not only affirm the species-level taxonomy of black maple but also represent the first characterization of genetic diversity within populations situated at the northern edge of its distribution range. Its high level of inbreeding is concerning for the conservation of the species in Quebec, and more research is needed to identify its origin.

Regulator of G protein signaling 14 (RGS14) is a multifunctional signaling protein that suppresses synaptic plasticity in the mouse brain. Our previous studies showed that RGS14 is highly expressed in postsynaptic dendrites and spines of pyramidal neurons in hippocampal area CA2 of the developing mouse brain. However, our more recent work with adult rhesus macaque brain shows that RGS14 is found in multiple neuron populations throughout hippocampal areas CA1 and CA2, caudate nucleus, putamen, globus pallidus, substantia nigra, and amygdala in the adult rhesus monkey brain. In the mouse brain, we also have observed RGS14 protein in discrete limbic regions linked to reward behavior and addiction, including the central amygdala and nucleus accumbens, but a comprehensive mapping of RGS14 protein expression in the adult mouse brain is lacking. Here, we report that RGS14 is more broadly expressed in mouse brain than previously known. Intense RGS14 staining is observed in specific neuron populations of the hippocampal formation, amygdala, septum, bed nucleus of the stria terminalis, and nucleus accumbens. RGS14 is also observed in axon fiber tracts including the dorsal fornix, fimbria, stria terminalis, and the ventrohippocampal commissure. Moderate RGS14 staining is observed in various other adjacent regions not previously reported. These findings show that RGS14 is expressed in brain regions that govern aspects of core cognitive functions including sensory perception, emotion, memory, motivation, and execution of actions, and suggests that RGS14 may serve to suppress plasticity and filter inputs in these brain regions to set the overall tone on experience-to-action processes.

Paraffin wax is derived from petrochemicals, which release harmful substances when burned in the form of candles. Beeswax serves as a natural and renewable alternative for making candles, offering cleaner burning that is safe for humans. The beeswax was mixed with virgin coconut oil (VCO) of 0 wt% to 55 wt% by weight at a temperature ranging from 75 °C to 85 °C. The resulting mixture was then cooled down in a glass container that had a wick installed. The wick was then burned to assess the candle’s performance. Beeswax candles have the slowest burning rate compared to other candles on the market. The best mixing temperature for melting and blending both materials without altering composition is 75 °C. Additionally, the incorporation of VCO in beeswax candle production can enhance performance by up to 35.4 % due to the reduction of the melting point, which increases the diffusion of wax into the wick.

Due to a high burden of neurocognitive impairment on patients with a pediatric brain tumor, interventions mitigating these symptoms are highly needed. Currently, evidence on the efficacy and feasibility of such interventions remain scarce. A systematic literature study was performed based on four different databases (PubMed, Web of Science Core Collection, Embase and PsycArticles). Resulting articles (n=2232) were screened based on title and abstract, and full text. We included 28 articles, investigating cognitive effects of either a lifestyle intervention (n=6), a cognitive training (n=15), or pharmacological intervention (n=7). The most frequently studied interventions were the Cogmed and methylphenidate. Most interventions showed short-term efficacy. Fewer interventions also showed long-term maintenance of positive results. Despite positive trends of these interventions, results are heterogeneous, suggesting relatively limited efficacy of existing interventions and more potential of more individualized as well as multimodal approaches for future interventions.

This Letter presents the creation, examination, and properties of a compact short pulse radar antenna for close-range pulsed radar imaging applications. We conducted an in-depth study on the antipodal Vivaldi antenna by varying the slope of its exponentially tapered radiating element and meticulously analyzed the resulting pulse response in the time domain. To determine the most effective design, we introduce an evaluation criterion (EC). Utilizing this EC, Case3 exhibits the best performance from a time domain perspective, with parameters of n_1,n_(2,) n_3,and n_4 are 4,1,1,9, respectively. Additionally, we introduce a resistance-tapered Vivaldi antenna designed through an innovative formula. This leads to a size reduction of approximately 50% compared to conventional antennas of equivalent length.

Consumers come across Glassware in our everyday lives, acting as a basic need for serving and storing, laboratories, etc. The Glassware market heavily relies on both its aesthetics and ergonomics. A visually appealing design significantly impacts the number of beverages served. The Glassware market heavily relies on both its aesthetics and ergonomics. Ergonomics is also used as a vital component in marketing campaigns to draw in customers. This empirical paper highlights the significance of having a holistic approach toward ergonomically designed glassware with specific reference to the beverage (juice). Experimenting with the same and a mirage about the quantity got tested. The expected insights of the chosen product are intuitively designed for ease of use. This study illustrates the role played by ergonomics and design. The samples were categorically analyzed based on aesthetics and quantity of glassware served in kiosks in the Vellore district and the results were obtained.

Purpose: This observational study aimed to assess the comparative effectiveness of immunotherapy (IO) in the second-line setting of advanced Non-Small Cell Lung Cancer (aNSCLC). Methods: Population-based data was obtained from the Cancer Registry of Norway (CRN) and linked with the hospital data from the Norwegian Patient Registry (NPR) and treatment data from the Norwegian Prescribed Drug Registry (NorPD). Adult patients with aNSCLC diagnosis in Norway in 2015-2021 were included. The final cohort included patients using IO in the second line setting after first-line treatment with platinum-containing doublet chemotherapy. We performed target trial emulating key eligibility criteria commonly used in aNSCLC randomized clinical trials (RCTs) and constructed three pair-wise 1:1 Propensity score (PS) matched comparison cohorts: atezolizumab versus pembrolizumab, atezolizumab versus nivolumab and nivolumab versus pembrolizumab. Age, sex, morphology, ECOG performance status, PDL1 expression level, peripheral vascular disease, chronic lung disease, diabetes without complications, heart failure, moderate to severe kidney disease, cerebrovascular disease, number of comorbidities per patients and etoposide use were included in the PS. The primary outcome was overall survival (OS). Patients were followed until experiencing death, emigration or end of study. A Cox proportional hazards regression model was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results: Analyses included a total of 463 patients, 215 users of atezolizumab, 72 nivolumab and 176 pembrolizumab. The median follow-up time was 8.4 (IQR 3.4—20.7) months. We found no significant difference in OS in any of the three pair-wise comparisons; atezolizumab vs. pembrolizumab (HR 0.92; 95% CI: 0.68—1.23), atezolizumab vs. nivolumab (HR 1.14; 95% CI: 0.78—1.67) and nivolumab vs. pembrolizumab (HR 1.11; 95% CI: 0.73—1.71). Conclusion: The study indicates that the three IO drugs atezolizumab, nivolumab and pembrolizumab, when used in second line aNSCLC, demonstrate a similar level of effectiveness. To substantiate these results, further investigation with larger-scale studies is required.

This study presents an innovative control framework designed for voltage source inverters (VSIs) equipped with LC output filters. The primary objective of this control structure is to reduce delay and suppress aliasing by employing a voltage double-loop univariate active damping strategy.The stability of the system is degraded because the control delay limits the bandwidth of the system.It has been shown that although the multisampling method can effectively reduce the delay,it also suffers from the problems of pulse loss and multiple comparisons, which leads to significant aliasing and ultimately affects the output power quality.To solve this problem, a multiple notch filter with small phase delay is adopted to suppress aliasing.The optimal parameters of the system are determined by considering the filter parameters, filtering effect, output voltage ripple content, and system performance in combination with the actual filtering requirements and circuit size.Its effectiveness and performance are carefully verified by experimental results.

During the past decade, most global firms have adopted the global software engineering approach for outsourcing their software development projects to reduce their cost and time-to-market, enhance their access to the competitive market, and advance their technical skills and resources. This paradigm shift from conventional geographically-bound development to a globalized software industry has happened due to an abrupt improvement in information and communication technologies. One of the successful paradigms of global software engineering is offshore software development, which has turned into an extremely beneficial industry for many of its stakeholders. However, this industry is posed with many impeding factors that impede the successful completion of numerous outsourcing projects. In this study, we have detected several significant impeding factors faced by the outsourcing industry. We employed a Systematic Literature Review (SLR) methodology and utilized constructed search criteria originated from our anticipated research questions, followed by choosing the particular research articles, inclusion and exclusion criteria, data extraction, and data synthesis, which resulted in 16 impeding factors from 118 final selected papers that were published between 2010 and 2024. Among these, eight impeding factors were identified as Critical Impeding Factors (CIFs). Furthermore, the investigated impeding factors have been analyzed by considering different scenarios, such as region-wise, research strategy based, and organization size. Our results can play a vital role for the outsourcing industry in improving its procedures to enhance their communication strategies, contract negotiation and management processes, cultural and language issues, and project monitoring.

Straw return into the field reduces the reliance on chemical fertilisers, promoting sustainable straw utilisation, and mitigating soil nodulation associated with excessive chemical fertiliser application. In this study, we investigated the effects of straw return on soil carbon and nitrogen fractions and the structural and functional diversity of soil microbial communities. We set up four treatments: S0 (0% straw returned to the field), S1/2 (50% straw returned), S1 (100% straw returned to the field), and S2 (200% straw returned to the field). The results revealed that most carbon and nitrogen fractions increased with increased amounts of straw returned into the field (soil organic carbon and total nitrogen: 6.4–39.8 % and 2.9–15.1 %, dissolved organic carbon and nitrogen: 1.4–37.9 % and 20.2–33.1 %, microbial biomass carbon and nitrogen: 26.3–129.3 % and 4.7–62.6 %, and light organic carbon and nitrogen: 52.4–155.9 % and 72.6–166.7 %). High-throughput sequencing and Biolog-ECO revealed that straw return significantly altered the relative abundance of bacterial and fungal communities and enhanced soil carbon metabolism. Redundancy and correlation analyses and partial least squares path modelling revealed that Proteobacteria (P = 0.002), Acidobacteriota (P = 0.004), Mortierellomycota (P < 0.05), and amino acid carbon sources (P < 0.01) were correlated with the changes in soil carbon and nitrogen fractions. Returning straw to the field significantly boosted the soil carbon and nitrogen fractions and affected soil carbon pools, particularly the active ones, by markedly influencing soil bacterial activity and consequently altering the soil carbon pool content. Our results provide a scientific and theoretical basis for enhancing nutrient content in dryland wheat calcareous brown soil, establishing a healthy soil ecological environment, and improving quality and efficiency in wheat production.

The anatomy of three endemic species in Türkiye, previously classified under the genus Pseudosempervivum (Brassicaceae), considered as the N. aucheri species complex (Noccaea aucheri, N. sempervivum and N. mummenhoffiana) in this study, was comprehensively evaluated anatomically for the first time. To aid the taxonomy of these three species, known for their transitional forms and classification challenges, 15 different populations were sampled, covering the entire distribution range of the species complex. The study investigated anatomical characteristics, such as root, stem and leaf anatomy, as well as stomatal index, which complement morphological identification traits, and examined their correlation with environmental factors. Root diameter and root cortex diameter, which are considered important for distinguishing perennials, showed the highest values in N. mummenhoffiana populations, while N. aucheri populations showed considerable variability. Multivariate analyses highlighted the importance of stomatal cavity size in basal leaves and the number of myrosine cells in explaining anatomical variation. Correlation analysis between climatic variables and anatomical traits revealed associations with stomata and epidermis cell sizes in cauline leaves with temperature and precipitation. Overall, the measurements indicated significant variability in anatomical traits among the three species within the complex, failing to provide clear distinctions. Alternatively, our results support the notion that the three species studied may represent a single polymorphic species.

Background: Intestinal barrier dysfunction may lead to a break in tolerance and development of food allergy (FA). There is contradictory evidence on whether intestinal permeability (IP) is altered in IgE-mediated FA. Thus, we sought to determine whether IP differed between children with eczema who did (FA group) or did not (atopic controls, ACs) develop FA and whether peanut sensitization, allergy and early introduction impacted IP using serum biomarkers zonulin, soluble CD14, and Intestinal Fatty Acid Binding Protein among randomly selected participants enrolled in the Learning Early About Peanut allergy trial. Methods: FA group was defined as having at least one FA at either baseline (4-11 months) or 60 months of age (V60). ACs had eczema at baseline and no FA at either visit. Serum IP markers (sIPMs) were measured by ELISA at baseline and V60 and their relationship with clinical characteristics of participants were analyzed using parametric tests and linear regression models. Results: We evaluated 237 FA subjects and 76 ACs. sIPM levels were similar in FA subjects and ACs at baseline and V60. Age when the child first developed any FA (<1 year vs >1 year), eczema severity, peanut sensitization, peanut allergy, and early peanut introduction were not statistically significantly associated with sIPM levels. Total IgE and eosinophil levels, peanut-specific IgE, IgG4 and IgG4/IgE ratio were not correlated with sIPM levels. Conclusion: No differences in sIPMs were detected to support altered IP in infants with FA compared to ACs or following early peanut introduction among peanut sensitized children.

Background and objectives: In Yemen, there is currently no specific/published guideline for influenza vaccination. In addition, data on knowledge, attitude, and practice, regarding influenza vaccination among HCWs in Yemen is still not studied yet. This study was conducted to assess the knowledge, attitude, practice, and barriers regarding influenza vaccination among HCWs in Yemen. Methodology: Descriptive cross-sectional KAP study was conducted among HCWS in public and private health care sectors located in Southern-Eastern part of Yemen. The Online Raosoft software was used for sample size calculation. If an adequate knowledge level of 50% among HCWs for a maximum sample size with a margin of error of ±5% and 95% confidence interval, the required sample size was 415 after adding 10% for incomplete responses. The convenience sampling method was used to represent the different geographical locations. A self-structured questionnaire was adapted from various previous studies in Yemen and other surrounding countries regarding influenza vaccines. The questionnaire was modified following an evaluation of technical detail and cultural appropriateness by MOPH&P research Committee and cleared by WHO ethical committee. Descriptive statistics was used to describe the findings of the study regarding seasonal influenza and influenza vaccination. Results: A total of 415 HCWs participated in the study with a 100% response rate. The mean age of participants was 37 years (SD = 10.7) and most of the participants were young adult between 20-35 years (50.6%), out of them were female (37.8%). 64.1% of responders declared poor knowledge toward influenza vaccines. However, most of the responders 373 (89.9%) had never been vaccinated. Lack of knowledge about the disease and the vaccine (205, 49.4%) and lacking trust in the health system (128, 30.8%) were the mean reasons for no vaccination among study participants. A greater proportion of responders cited that, the means source of information about influenza vaccination is HCWs (310=74.7%). A 62.2% of participants believed that Influenza vaccine is important and should be taken yearly. The majority of the participants declared their positive acceptance 279= 67 %. Conclusion: This study highlights the fact that generally acceptance of influenza vaccination of healthcare workers in Yemen, and the need to increase efforts and awareness in the community including health care workers regarding influenza illness and vaccination to reduce seasonal influenza morbidity and mortality and consequently the economic and social burden. The findings of the current study could help devise an immunization policy for HCWs in Yemen.

Objective: To develop a multimodal artificial intelligence model based on medical health records, imaging information, and laboratory test indicators to assist in the diagnosis of Kawasaki disease. Methods: This study was conducted using the Kawasaki disease database from our hospital, retrospectively collecting medical information from a total of 500 children (both with Kawasaki disease and healthy). We designed a Chinese-BERT-Base module, a ResNet module, and a fully connected layer module to process medical records, image data, and laboratory test results, respectively. Subsequently, we utilized early fusion to concatenate the vectors and input them into a classifier for outputting classification results. We designed unimodal models and traditional machine learning models for comparative evaluation to assess the effectiveness of our model. We analyzed the attention of each module to the raw data to evaluate the interpretability of the model. Additionally, we collected data from another 100 children from a peer hospital as an external validation group. In a double-blind scenario, three senior doctors and the model performed classifications simultaneously for a human-machine comparison experiment. Results: The multimodal model developed in this study demonstrated significant improvements in accuracy (93%) and specificity (93%) compared to unimodal models and traditional machine learning models. Interpretability analysis showed that the attention of each module in the multimodal model largely aligned with the thought processes of human doctors. The human-machine comparison experiment indicated that the model’s classification performance (87%) still had a notable gap compared to that of the human doctors (98%). Conclusion: The multimodal model developed in this study effectively utilized clinical data, achieving good diagnostic performance and providing a relatively reliable tool to assist clinicians in diagnosing Kawasaki disease.

How might a “philosopher’s toolkit” contribute to progress in neuroscience? This paper addresses this question by first posing it to several neuroscientists, all with a track record of successfully interacting with philosophers. These discussions took the form of structured interviews following the strategy of Barwich (2020, 2021) and highlighted a number of issues these neuroscientists thought philosophers could help them solve; some of these problems were at the center of these neuroscientists’ research programs. Are philosophers willing and able to bring their “toolkits” to bear on problems like these? No definite answers to this question emerge from these interviews, but in our interactions it became obvious that philosophers will need real training in neuroscience to contribute to these concerns. Fortunately, over the past two decades, there are growing numbers of philosophers trained in the science-in-practice movement. Our collective findings should not only encourage them that they can genuinely contribute to neuroscience’s progress, but also that some neuroscientists will seek them out and highly value their contributions. These discussions can also guide other neuroscientists about ways to interact fruitfully with philosophers active in the field of science-in-practice.

As offshore wind power development extends into deeper and farther seas, several new AC/DC transmission schemes have been proposed. Each of these schemes has its own technical advantages. However, with the increasing complexity of transmission conditions, selecting the optimal techno-economic transmission system for different scenarios has become an urgent issue that needs to be addressed. Current single-dimension evaluation methods for offshore wind power systems lack comprehensive parameters and sufficient accuracy, making it difficult to accurately select systems for complex operating conditions. To address the above issues, this study first establishes a TLCC-BEP offshore wind power cost indicator that integrates multiple parameters such as water depth and taxes, combined with power generation benefits, environmental, and carbon indicators, proposing a comprehensive benefit evaluation system. Next, the characteristics of the main indicators in the constructed evaluation system are presented based on the results of model sensitivity analysis. Subsequently, using actual scenario GPS data, the VIKOR method based on prospect theory is applied to comprehensively evaluate four schemes—HVAC, FFTS, VSC, and CSC—under multiple conditions, obtaining a more accurate applicability range for each transmission scheme.

Multi-effect distillation shines as a thermal desalination technique due to its economic viability and broad range of application. It effectively tackles desalination for seawater and brackish water, regardless of capacity, using a low-temperature (below 70°C) evaporation and distillation process. This study employs exergy analysis to identify the components within a six-effect Multiple Effect Distillation (MED) system where exergy destruction occurs, followed by an exergy-economic analysis to evaluate the system’s overall performance. Exergy, representing the maximum obtainable work from a substance, is examined for both feed water and distillate in the context of their chemical potential differences. The calculated exergy values for different system states are presented, revealing the exergy destruction attributed to irreversibility such as friction and heat transfer. The system’s overall exergy efficiency is determined to be 74.47%, indicating that only this portion of feed water exergy is converted into useful distillate exergy. The remaining exergy is lost due to irreversibility. An exergy balance for the 6-effect MED system is provided, showing that 25.53% of the energy input is lost as exergy destruction. Three different economic model are used to estimate the distillate cost for different feedwater temperature and distillate cost found to be 3.63, 1.9, 2.45 $/m 3 respectively.

Developing single fluorescent probe for simultaneously visualizing mitophagy flux and oxidative stress with super-resolution is highly demanded yet quite challenging. Herein, we design and synthesize a ratiometric HClO probe AHOH, which is capable of simultaneously staining lysosomes and mitochondria with red and green color, respectively. AHOH could be selectivity oxidized by HClO, leading to a large emission blue shift (90 nm) and an over 1300-fold enhancement of the emission ratio of Fl547 nm/Fl637 nm. We apply AHOH in super-resolution microscopy and clearly visualize the dynamics of mitochondria-lysosomes interactions and the oxidative stress states upon different stimuli. Mitochondria dysfunction triggered by different drugs and genetic defect lead to elevated oxidative stress and higher levels of mitophagy. Moreover, AHOH could serve as a reliable tool for evaluating the efficacy of drugs regulating mitochondria dysfunction. This work provides a powerful dual-color super-resolution imaging agent for real time monitoring the dynamics of organelle interactions and oxidative stress.

This article focuses on the historical background of Indian education during the pre and post-independence eras. The core aim of the paper was on the comparative analysis of Indian National Education Policies. It is a historical and analytical study based on doctrinal and library methods. The educational policies of India are analyzed comparatively. Educational policy is the driving force for the actualizing of predetermined national goals. The National Education Policy of 1968 focused on a uniform educational system throughout the country. The national education policy of 1986 and 1992 was focused on quality and equality in the education sector of India. Recently the government of India announced its new Educational policy which is based on the recommendations of Dr. Kasturirangan, the former chairman of the Indian Space Research Organization (ISRO). The National Education Policy 2020 is an educational reform after 34 years, emphasizing more on holistic and multi-disciplinary approaches.

Plant growth and development are impacted by drought stress in terms of morphology, anatomy, and physiology. To identify the elite drought tolerant rice cultivar an attempt was made in the current study to screen the landraces collected from different agro climatic regions of Tamil Nadu. Seeds of 38 rice landraces and two check were evaluated with the standardized dose of -1.0 MPa PEG 6000. As a result eight landraces were proven to be drought tolerant and have a higher seedling growth characteristics under drought stress. Further, those selected eight landraces were subjected to morphological, physiological, and biochemical characterization to study the effect of drought tolerance. From the overall study, Kuliyadichan followed by Milagusambha was found to be promising with all the five morphological characteristics related to drought. For physiological characters, the cultivars Kuliyadichan, Milagusambha, and Rascadam recorded the highest score related to drought tolerance. The cultivars, Kuliyadichan, Milagusambha, Rascadam, and Kallundai are selected for all the biochemical traits. Also, the same cultivars recorded a higher percentage of spikelet fertility and Drought tolerant efficiency. Therefore, the cultivars Kuliyadichan, Milagusambha, and Rascadam could be the focus of a future rice breeding program to create varieties that are drought tolerant.

Developmental conditions including temperature, diet, and parasites can shape adult fitness phenotypes in many species. Studies typically focus on the additive effects of early-life and adult life conditions on life history response in the context of competing models of developmental plasticity (i.e. environmental matching and silver spoon). These models continue to yield mixed results in the same or different species. Here, we characterize interaction effects of larval vs adult diet on lifespan and fecundity in a high diversity outbred population of Drosophila melanogaster. We compare fitness proxies of matched vs mismatched early-to-late nutritional conditions differing in protein content. Diet interactions significantly affected both traits, albeit differently. We find no consistent evidence for either model. Rather, several patterns emerged including age and sex effects, survival differences in the post-median life phase, regime-specific timing of peak fecundity, and substantial fecundities in older post-median flies. We find that mild protein restriction increases both maximum lifespan of males and female lifetime fecundity. Surprisingly, lower adult protein delayed egg-laying by about 2 weeks, compared to treatments with higher protein in adult diet. This effect was particularly evident in treatments involving protein-restricted developmental diets. Our results highlight the need for assessing patterns of response over the course of life which can potentially reveal more subtle interacting processes compared to cross-sectional measurements. In addressing the impacts of environmental change in natural systems, it will be necessary to consider nuanced approaches that account for both, additive and interaction effects in diverse genetic backgrounds.

IntroductionSyncope is a transient, self-limiting loss of consciousness and an inability to maintain postural tone due to reduced cerebral blood flow, which is followed by spontaneous recovery. Affecting 1-3% of the elderly population, it represents a challenging problem in medical practice because the causal mechanism often remains uncertain even after extensive and expensive evaluations.1 Syncope may be caused by a variety of factors, including cardiovascular, neurological, and metabolic disorders, and its presentations are quite variable. However, the most common causes of syncope are neurocardiogenic or vasovagal syncope, which account for up to 50% of cases.1 This type of syncope is typically triggered by emotional distress, pain, or orthostatic stress and is characterized by a sudden drop in blood pressure and heart rate. In the literature, some authors have described cases of “vestibular syncope” in which vertigo may cause syncopal attacks.2,3 However, the term “vestibular syncope” determined a lot of confusion since it has been ascribed to completely different vestibular conditions, varying from dizziness4 to Tumarkin in Menière disease (MD),5 in which the patients experienced a severe immediate drop episodes without loss of consciousness.6 The same term has also been ascribed to the neurovegetative symptoms in benign paroxysmal positional vertigo (VPPB) or fainting after otholitic maneuvers.7Vestibular syncope has also been addressed in the non-autonomic neurological causes of syncope8 and in central vertebrobasilar hyperfusion.9
