Published: May 2022

Abstract
Background
Recent studies showed a connection between pyrodiversity and biodiversity in the western US, but few examined bird response to fire severity in eastern hardwood forests. We measured forest structure and conducted avian point counts for five years (2016–2021; Y1-Y5) in three burned and three unburned watersheds following mixed-severity wildfires to compare breeding bird communities across a fire-severity gradient (no burn (NB), low (L), low-moderate (LM), moderate (M), moderate-high (MH), and high (H)) in the southern Appalachian region.
Results
The percentage of wildfire-killed trees increased with fire-severity category (FSC) and over time; by Y5, 74% (48% BA) were dead in H compared to 11% (3% BA) in L. Post-wildfire shrub recovery was rapid, especially in H and MH where cover exceeded all other FSCs by Y5. Total bird abundance and species richness increased with increasing fire severity (no change in NB and L) and exceeded all other FSCs in H and MH by Y5. Most (12 of 18 tested) species were unaffected by wildfire severity. Disturbance-dependent chestnut-sided warbler (Setophaga pensylvanica), indigo bunting (Passerina cyanea), and eastern towhee (Pipilo erythrophthalmus) increased in H within 3–4 years; white-breasted nuthatch (Sitta carolinensis), hooded warbler (Setophaga citrina), and blue-headed vireo (Vireo solitarius) increased in some burned FSCs and years. Shrub-nesters were more abundant in H than all other FSCs except MH and increased over time in H, MH and LM. Cavity-nesters were more abundant in H, MH and M than L or NB, but primary cavity-nesters (woodpeckers) alone were not.
Conclusions
Our results highlight the interrelated roles of fire severity and time in driving breeding bird response in central hardwood forests, illustrated by sharp contrasts in bird responses between L (no effects) and higher-severity (H and MH) burns that promoted disturbance-dependent species, but also a more gradual increase in total bird abundance and species richness in LM and M corresponding with delayed tree mortality and shrub recovery. We suggest that high-severity burns are more important than pyrodiversity per se in promoting bird diversity, as disturbance-dependent species were mainly associated with high-severity burns whereas no species was limited to unburned forests or lower-severity burns (L-M).

Abstract
BackgroundIndividuals with mental health disorders have a higher risk of sexual problems impacting intimate relations and quality of life. For individuals with bipolar disorder (BD) the mood shifts might to a particular degree affect their sexual function with possible hypersexual interest during manic episodes and with low sexual interest during depressive episodes. The diagnosis is often given in late adolescence, which may impact sexual identity and development. Only few studies have looked at BD and sexual life, with no qualitative research on the topic. We conducted a qualitative pilot study exploring sexuality in connection to mood swings in five participants with BD. ResultsThematic content analysis revealed five themes: 1) sexual drive and impulses, 2) sexual behavior, 3) thoughts and feelings in relation to sexual issues, 4) intimate relationships, and 5) sexuality and identity. During manic episodes the participants described having a higher sexual drive, leading for some to more sexual interactions. During depressed episodes, the sexual drive in the three female participants were low, however, in the two men, rather than a reduced sexual drive, a more self-destructive way of engaging in sex prevailed. The sexual outgoing behavior during manic phases was described as joyful, with no feelings of shame connected to it. However, the shifts in sexual drive connected to mood shifts affected the participants’ relationships negatively. Further, all of the participants described having an outgoing sexual behavior in their youth and before a diagnosis of BD. ConclusionsThe findings suggest that changes in sexual drive may act as a trigger or early warning symptoms of new episodes, pinpointing the clinical relevance of addressing sexual in individuals with BD. Further, all participants described having an outgoing sexual behavior in their youth before the onset of BD, which might be essential to consider if there is a clinical suspension of BD in an individual.
Proprioceptive vibratory stimulation modulates cortico-muscular postural response
Authors: Barollo Fabio , Rigoni Isotta , Gargiulo Paolo , Fratini Antonio 
Published: May 2022

Abstract
For decades, postural control has been believed to be dominated by reflexive mechanisms, but more recent evidence characterizes it as an articulate system which relies on multisensory integration (vestibular, visual, proprioceptive) and cortical coordination to preserve balance in the wake of external disruptions to the quiet stance. Corrective strategies to stabilise the body’s center of mass and prevent falls are planned at the central nervous system level and executed through the modulation of muscular activity, especially in the lower legs muscles: gastrocnemius, soleus and tibialis. In this study, we use localized proprioceptive vibratory stimulation to induce a perturbation of the subjects’ quiet stance. By integrating traditional force plate data with electrophysiological signals (EEG and EMG), we use cortico-muscular and inter-muscular coherence to investigate how brain and muscles interact to shape an effective response to a postural challenge. Our results show how the cortical drive is enhanced in beta [13-30]Hz and gamma [30-45]Hz bands, specifically for the soleus and gastrocnemius muscles, during the task execution. We also reveal a remodulation of the lower legs muscle network, with a distributed strengthening of muscle activity coupling.

Abstract
Background
Assessing thromboembolic risk is important for patients with atrial fibrillation. The use of new scanning techniques in clinical practice has not been sufficiently investigated. This study aimed to determine the efficacy of left lateral decubitus computed tomography for diagnosing left atrial appendage (LAA) thrombus as a screening tool before catheter ablation and to evaluate the risk factors for thrombus formation.
Methods
This retrospective cohort study included 101 patients. All patients underwent transthoracic echocardiography (TTE) and left lateral decubitus cardiac computed tomography (CT). Transesophageal echocardiography (TEE) was provided only to confirm the LAA thrombus. Patients with allergic reactions to iodide, increased creatinine levels, hyperthyroidism, pregnancy, and age < 18 years were excluded. The CHA2-DS2-VASc and HAS-BLED scores were calculated in each patient.
Results
All LAA thrombi detected on CT were confirmed on TEE. Higher CHA2-DS2-VASc, HAS-BLED scores, enlarged left atrium, and the anteroposterior dimension of the left atrium were significantly associated with LAA thrombus. An LAA cauliflower shape is a predictor of LAA thrombus. An increase of LAA volume by 1 cm3 increases the chances of LAA thrombus and cerebral infarct by 2%. The growth of the LAA anteroposterior size by 1 cm increases the risk of LAA thrombus by 2.9 times and of cerebral infarct by 78%. An increase in the CHA2DS2-VASc score by 1 point increases the risk of thromboembolism and cerebral infarction by 12%.
Conclusion
Cardiac CT with the patient positioned on the left side is a good screening tool to determine LAA thrombus and provides highly useful information for predicting thrombosis formation risk in LAA.
Would you own a ROBOT? : A detailed research on
public response to the nooks and crannies of owning a robot
Authors: Dahal Ashim 
Published: May 2022

Abstract
The utility aspects of robots in our day to day tasks have been diminished over the fear of them taking over humanity, especially thanks to unrealistic movies. But how much should the public care about having or owning a robot? What tasks do we want robots to do? Which workforce do we want a robot to join? How comfortable are we sharing our data with a robot? And given the circumstances of an economy sustained by our automated metal friends, will we still want to continue our jobs? In this research, we try to find answers to all these questions.

Published: May 2022

Abstract
Ecological restoration of degraded areas can be important to prevent or slow down invasions of alien species. The objective of this study is to evaluate the potential of native species in applying the seeding technique and to compete with the invader Eragrostis plana, aiming ecological restoration at Campos Sulinos grasslands (South Brazil). Seeds of six native species (Anthaenantia lanata, Aristida laevis, Aristida jubata, Chamaecrista repens, Panicum olyroides and Paspalum plicatulum) and of E. plana were sown in isolated and competition (one native species plus the invader) pots. Germination rate, survival rate, germination rate index (GRI), above and belowground biomass were analyzed using ANOVAs and GLMs, and the impact of native species’ attributes at the invader biomass were analyzed using linear regressions. We found that Arista laevis and A. jubata had the highest germination and GRI, although had low survival. Anthaenantia lanata and Paspalum plicatulum had medium germination rate and GRI, but P. plicatulum had high survival and was the only native species to achieve a great biomass development. The invader proved to be a great competitor, with a high GRI, germination and survival rate and biomass production. High germination speed didn’t inhibit the early growth of the invader, although our results show that a high production of native biomass can slow down the development of E. plana. The only native species that was as predominant as the invader at the competition pots was P. plicatulum, and further studies can be important to understand the dynamic between those two species.

Abstract
Background: Differentiated thyroid cancer is the most frequent malignant endocrine neoplasia in the world. Papillary thyroid cancer (PTC) is the most common type and has the best prognosis. BRAF mutations are reported in 40–70% of patients and are associated with worse prognostic factors. Materials and methods: A bispective diagnostic test study was carried out by real-time PCR, immunohistochemical and histological tests in patients diagnosed with thyroid cancer between 2013–2016 and who participated in a study of the BRAF V600E mutation at the Fundación Valle del Lili University Hospital (FVL) in Cali Colombia. Results: Samples from 18 patients with papillary thyroid carcinoma were evaluated by a real-time PCR test for the BRAF gene. It was determined that 69% of the samples had histological characteristics suggestive of the mutation; however, when compared with PCR, the performance of the histological observations had a sensitivity of 100% and specificity of 75%. On the other hand, immunohistochemistry showed a sensitivity of 93% and a specificity of 50%.Conclusion: Immunohistochemistry and histology features can be used as an alternative test to molecular sequencing. Compared with PCR, these tests show great sensitivity and low specificity. Molecular confirmation of the mutation is necessary.

Published: May 2022

Abstract
Background: The effect of coupled plasma filtration adsorption(CPFA) for the treatment of sepsis or septic shock is controversial. A systematic review and meta-analysis was performed to evaluate the impact of CPFA on all-cause mortality in patients with sepsis or septic shock.Methods: We searched the PubMed, Cochrane, and Embase databases for randomized controlled trials(RCTs) and cohort studies from inception to the 1st of May 2022. We included studies involving patients (˃14 years) with sepsis or septic shock. All authors reported our primary outcome of all-cause mortality(hospital mortality, 28-day mortality or 30-day mortality). Results were expressed as odds ratio (OR) with accompanying 95% confidence interval (CI).Results: Six studies including 537 patients were included. The primary outcome of this meta-analysis showed that the all-cause mortality was about 54.2% (119/243 in the CPFA group and 172/294 in the control group). There was no statistically significant difference in the all-cause mortality between two groups(odds ratio [OR]=0.75;95% CI, 0.53 to 1.06; P=0.11;Chi2=14.04; I2=64%).Conclusions: The treatment of CPFA failed to decrease all-cause mortality of sepsis or septic shock patients. Further large-scale randomized controlled trials (RCTs) evaluating the ability of this therapy to improve clinical outcomes are still required to confirm these results.

Published: May 2022

Abstract
Background
Antibiotic resistance genes (ARGs) can be transferred from environmental microbes to human pathogens, which could lead to treatment failure of bacterial infections. The aquaculture, which is polluted by current and past over-used antibiotics, is considered as a notorious reservoir of ARGs. However, the fact on the mobilization of ARGs in aquaculture systems, and their contributions to the emergence and dissemination of antibiotic resistant bacteria (ARB) remain elusive.
Results
We used crayfish as an aquatic animal model to analyze longitudinal changes of bacterial communities, ARGs and mobile gene elements (MGEs) in the gut and sediment samples in response to enrofloxacin administration. Our metagenomic analysis revealed significant perturbations of the microbiota and ARGs compositions in the gut compared to those in sediments, which is characterized by a obviously delayed recovery after antibiotic administration. The significantly positive correlation between the total abundance of ARGs and MGEs was observed and MGEs were frequently located close to ARGs in genomes of the bacteria from Enterobacteriaceae. These mobile ARGs had high intracellular and intercellular transferred potential by transposon-mediated recombination in gut and sediment samples in the pressure of antibiotics. In addition, multiple antibiotic resistant pathogens of Enterobacteriaceae and other new ARBs had emerged and proliferating under the pressure of antibiotic.
Conclusion
Our findings showed that MGEs facilitated the diffuse of ARGs through horizontal gene transfer mainly in the bacteria from Enterobacteriaceae family in gut and sediment environments. Especially, the transposase-mediated recombination was the major driver of the transfer for ARGs in the pressure of antibiotics. Simultaneously, the changes in community composition as the emerged and proliferating of the multiple resistant pathogenic bacteria played a crucial role in the augment of various ARGs.
Parents perspectives on communications with physicians at the point of initiation of invasive long-term ventilation of a child: a scoping review
Authors: Greene Jo , Quirke Mary Brigid , Alexander Denise , Doyle Carmel , Brenner Maria 
Published: May 2022

Abstract
Purpose
An increasing number of children with complex and integrated care needs (CICN) are dependent on medical technology such as invasive long-term ventilation (LTV) to sustain their lives. However, the sensitive nature of communications between parents and physicians at the point of initiation of technology dependence is under explored. A systematic scoping review was conducted to map existing research and understand the range of parental perspectives on communications with physicians at this key decision-making milestone.
Methods
Guided by the methodological framework of Arksey and O’Malley, a three-step screening process resulted in ten articles from the 445 initially identified, as meeting the selection criteria for inclusion. Adopting Braun and Clarke’s approach, this qualitative evidence was thematically analysed.
Results
Three overarching themes emerged which describe communications at the point of initiation of LTV: the need to ventilate, navigating medical decision-making and perceptions of communications with physicians.
Conclusions
Parents are located at the centre of the decision-making process, but their lack of knowledge of uncommon but critically needed medical interventions places them at a disadvantage. They frequently feel overwhelmed by the need to make quick decisions without complete information, this loss of control can be amplified in the complex environment of the healthcare setting. In communications with physicians, parents value a collaborative and responsive approach to their information needs which facilitates them to make ethical decisions that are appropriate for the long-term care of their child.

Abstract

The broader socioeconomic impact anticipated to occur in the coming decades with the advent of nanoscience and nanotechnology has led many countries to establish national nanotechnology initiatives to promote nanotechnological developments. One major resolution under these mega initiatives is to popularise nanotechnology as a subject at the high school and university levels. However, teaching nanotechnology concepts at the high school level still remains challenging mainly due to the inherent complexity of the associated principles and the unavailability of resourceful talents to teach the subject. Herein, we disclose the development of a nanoscience and nanotechnology educational tool kit for innovative and interactive teaching and learning of nanotechnology at the high school level. This portable tool kit includes several interactive activities such as puzzles and games to understand and visualize nano-scale, synthesis of simple nanomaterials with readily available chemicals, experiments to understand the nano-scale properties, activities to identify nanotechnological effects in nature, and day-to-day life applications in a domestic environment. Several workshops were conducted under the patronage of the National Science Foundation, Sri Lanka to introduce and familiarise this tool kit with both teachers and high school students. The major objective of this design is to multiply the model kit in order to distribute among the school teachers to easily transfer the new field of study to the students by generating interest to extrapolate the theoretical knowledge to real-life situations.
Does External Debt Promote Human Longevity in Developing Countries?
Authors: Aladejare Samson Adeniyi 
Published: May 2022

Abstract
This study assessed the impact of external debt on longevity in developing countries, particularly in West Africa, from 1981 to 2020. Longevity was proxied by life expectancy at birth, while the external debt effect was evaluated from the perspective of sustainability, liquidity, and solvency. Furthermore, outcomes from macroeconomic volatility were controlled through inflation and exchange rate variability. Methodological robustness was ensured by adopting panel unit root, cointegration, and estimation procedures incorporating panel dataset cross-sectional dependency and heterogeneity in their estimation process. Robust inferences for the study were derived by comparing estimated outcomes from the cross-sectional augmented autoregressive distributed lag, dynamic common correlated Effects, and the Driscoll-Kraay method. Empirically, the study showed that unsustainable, illiquid, and insolvent external debt and macroeconomic volatility shorten longevity in West African countries. Hence, longevity will decline when weak external debt management promotes poverty in West Africa and other developing countries.

Abstract
Specially defined Calabi-Yau manifolds having the hypersurfaces of degree - 5 in ℙ⁴ satisfying the non-trivial canonical bundle Λˣ₃ where the embedding holomorphic map ψ∶ X⟶ ℙ with the Kähler form for holomorphic line bundle giving a strictly positive parameter ℓᵏ ⨂ ∃k > 0 representing ℓ through the first Chern Class H² (2,ℤ). When for every Kähler Class , the Cohomology class exists with the compact form (X,ω) ∀ potential spaces satisfying H²ₔᵣ (X) with the ∂∂*−lemma for a harmonic form giving us the (1,1)⁺ − Kähler potential 𝒊2⁻¹∂∂*ρ. Taking all this in effect and making it established through various conjectures, axioms, ideals, theorems – an equivalence class is shown between the structures: Kahler-Manifold, Calabi-Yau-Manifold, Hyperkahler-Manifold, Quintic-3-Fold, Kummer Surface, K–3 Surface, De Rahm Cohomology Class (Hol(Ω(μ,ν)). The extreme case considered here is the exclusion of Complex hyperbolic Kahler – represented by ℂℙⁿ ∀n = -1. In course of making this paper the non–trivial aspects concerning the topological structures in aspects of string theory, the compact Kahler with a Ricci–flatness explained here.
