Stage directions are a special type of genre in theater, ranging from indications for the dramatic text to the emergence of the author’s voice. In Eugène Ionesco’s case, stage directions go beyond his plays and find another function in his critical writings and in his correspondence with directors. In this paper, we analyze how stage directions function in the texts published in Notes et contre-notes and in the manuscripts housed in Ionesco’s Archives, from the perspective of a theoretical debate that involves Bernard Dort, Roland Barthes and Luiz Fernando Ramos, among other researchers interested in theatricality.

As didascálias constituem um gênero muito particular no domínio teatral: das indicações cênicas à inscrição de uma voz autoral no texto feito para ser representado. Na produção de Eugène Ionesco, as didascálias fogem das peças para encontrar uma função a mais em seus textos críticos e na correspondência com seus diretores. Neste artigo, trata-se de analisar a inserção das rubricas nos textos publicados em Notes et contre-notes e nos manuscritos do Fundo Ionesco, com base em uma discussão teórica sobre o gênero e a relevância da figura autoral, a partir de Bernard Dort, Roland Barthes e Luiz Fernando Ramos, entre outros pesquisadores da teatralidade.

- Abstract
Atrazine is one of the most used herbicides in the world, although it is banned in several countries. Pollution of terrestrial and aquatic ecosystems represents a threat to non-target organisms, with various damages already reported in different species. However, there is controversy in studies on atrazine. The question of whether atrazine increases animal mortality is not yet clearly resolved. In this context, this study aimed to carry out a meta-analytic review, focusing on studies on environmental concentrations of the herbicide atrazine to evaluate its lethal effects on various animal species. We identified and analyzed 107 datasets through a selection process that used the Scopus, PubMed, and Web of Science (WoS) databases. A significant increase in the mortality rate of animals exposed to environmental concentrations of atrazine was observed. Nematodes, amphibians, molluscs, insects, and fish showed increased mortality after exposure to atrazine. Animals in the larval and juvenile stages showed greater susceptibility when exposed to different concentrations of atrazine. Furthermore, both commercial and pure formulations resulted in high mortality rates for exposed animals. Atrazine and other pesticides had a synergistic effect, increasing the risk of mortality in animals. There are still many gaps to be filled, and this study can serve as a basis for future regulations involving atrazine., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

- Abstract
Down syndrome (DS) is a common chromosomal disorder with distinct phenotypes and skin markers. This study reports 39 DS patients, aged 1-44 months, who presented from birth with rough, brownish skin in the dimples of their knees and/or elbows. Dermoscopy revealed hyperkeratosis with brownish scales, and biopsies in six cases showed papillomatosis and mild hyperkeratosis. In the cases followed, the condition resolved spontaneously. Hyperkeratosis in the skin dimples on the knees and elbows seems to be a congenital and perhaps characteristic finding in patients with DS., (© 2024 Wiley Periodicals LLC.)

- Abstract
Background: The impact of the COVID-19 pandemic on breast cancer care across Brazilian regions with varying Human Development Index (HDI) levels remains unclear. This study evaluates the pandemic's effects on screening mammograms, tumor staging at diagnosis, and treatment initiation in the Brazilian Public Health System between 2017 and 2022, focusing on regions with different HDI levels., Methods: This ecological time series study uses an inflection point regression model and monthly percentage change (MPC) to analyze an open-access Brazilian Public Healthcare System dataset. The study focuses on trends and variations in these variables among women aged 50-69 in three state groups classified by HDI: Group A (very high), Group B (medium), and Group C (high)., Results: The average monthly rate of screening mammograms was highest in Group A (10.70) and lowest in Group B (8.38). At the onset of the COVID-19 pandemic, screening rates dropped significantly, with the most significant decline in Group B (58.6% decrease) and the smallest in Group A (45.7% decrease), lasting for three months. Subsequently, this variable recovered until December 2022 but was insufficient to restore the total series MPC to pre-pandemic levels. Group B had the lowest average rate of early-stage (0-II) diagnoses (2.88), while Group C had the highest (3.68). Early-stage diagnoses declined in the first three months of the pandemic, followed by a partial recovery that was insufficient to restore the pre-pandemic MPC levels. The proportion of advanced-stage diagnoses was highest in Group B (49.02%) and lowest in Group A (45.97%). The pandemic maintained the upward trend of advanced-stage (III-IV) diagnoses across all groups in the total time series. The average proportion of treatments initiated after 60 days of diagnosis was above 60% across all groups, with Group B at 64.50%. This variable began to rise 3 to 4 months after the pandemic and continued increasing until December 2022, with a greater intensity than the pre-pandemic period across all groups., Conclusion: The COVID-19 pandemic reduced breast cancer screening and early diagnosis in Brazil, leading to more advanced cases and treatment delays across all regions, with varying impacts according to regional HDI levels., (© 2024.

Arten TLS and Hamdan AC
- Abstract
Parkinson's disease (PD) is a neurological disorder that primarily affects movement and is often accompanied by depressive symptoms. Subthalamic nucleus (STN) deep brain stimulation (DBS) has emerged as a therapeutic intervention for PD, although its impact on depressive symptoms remains complex. This study investigates the relationship between PD, DBS, and depressive symptoms, focusing on how DBS influences cognitive function and mood among PD patients in Brazil. The study involved two cohorts: one in 2019 with 46 participants and another in 2022 with 31 patients. Distinct assessment instruments, including the Geriatric Depression Scale-15 and Beck Depression Inventory-II, were employed to evaluate depressive symptoms. The results revealed no significant correlation between participants' gender and the presence of DBS, but substantial differences were observed in age, disease duration, and Activities of Daily Living scores. Patients undergoing DBS showed notably poorer cognitive performance compared to those treated solely with medication. Furthermore, the use of DBS was associated with higher scores on depressive symptoms scales within one of the cohorts. These findings underscore the intricate interplay among PD, DBS treatment, and depressive symptoms, highlighting the necessity for tailored approaches to patient care.

- Abstract
Conventional methods for diagnosing tuberculosis (TB), a significant global health challenge, often have drawbacks like time-consuming procedures, limited sensitivity, and the need for complex, expensive infrastructure. Hence, the development of electrochemical immunosensors has emerged as a promising strategy for TB detection due to their simplicity, speed, sensitivity, portability, and cost-effectiveness. In this study, we developed a rapid, simple, and low-cost immunosensor using a lab-made screen-printed electrode (SPE) based on the peptide TB 68-G as a recognition site. This synthetic peptide is composed of two important parts, one with an affinity for graphene materials and the other able to interact with anti-M. tuberculosis antibodies. This structural configuration allows for effective modification of the electrode surface while maintaining the ability to recognize the target. The proposed label-free electrochemical immunosensor was tested against M. tuberculosis antibodies and demonstrated a detection limit of 192 ng mL
-1 with an R2 value of 0.98. The diagnostic platform exhibited selectivity against nonspecific antibodies and successfully differentiated between negative and positive human serum samples with a 95 % confidence interval. This simple and affordable immunosensor holds great potential to impact TB control by enabling effective detection and improving disease surveillance., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

- Abstract
Background: The COVID-19 pandemic has overwhelmed the healthcare systems of many countries and negatively impacted the care of other diseases., Objective: To evaluate the trend of screening mammograms, oncological breast surgeries, and breast cancer hospitalizations in Brazil's public and private healthcare system between 2014 and 2022., Method: This ecological time series study uses the inflection point regression model and semester percentage change (SPC). We use the open-access dataset of the different healthcare systems in Brazil. We analyzed the trend of the variables in the pre-pandemic and the effect of the pandemic on the total time series., Results: In 2020, compared to 2019, the decrease in screening mammograms, oncological breast surgeries, and breast cancer hospitalization was - 41.44%, -23.13%, and - 10.52% (public health system) and - 29.49%, -18.96%, and - 15.35% (private healthcare system). In the public healthcare system, the pandemic has enhanced the decreasing trend of mammograms (SPC - 1.6% before and - 3.4% after), has reverted the stationary trend of oncological breast surgeries to decreasing (SPC - 1.0%), has slowed the increasing trend of breast cancer hospitalization (SPC 1.8% before and 0.9% after). In the private healthcare system, the pandemic has reverted the stationary trend of mammograms to decreasing (SPC - 1.0%), has slowed the increasing trend of breast cancer surgeries (SPC 2.3% before and 0.8% after), has reverted the growing trend of breast cancer hospitalization (SPC 3.9%) to stationary., Conclusion: During the COVID-19 pandemic, there was an increase in inequalities between healthcare systems, especially in breast cancer screening., (© 2024.

- Abstract
Spiders of Loxosceles genus, or Brown spiders produce a potent venom with minimal volume and protein content. Among its toxins, phospholipases D (PLDs) are notable for causing primary local and systemic manifestations observed following envenomation. They degrade cellular phospholipids, mainly sphingomyelin and lysophosphatidylcholine. We present a robust and detailed analysis of PLD transcripts from venom glands of three major clinically relevant South American species-L. intermedia, L. laeta, and L. gaucho-using next-generation sequencing. Results confirmed that PLDs are the most highly expressed toxins, accounting for 65.4 % of expression in L. intermedia, 71.8 % in L. gaucho, and 50.4 % in L. laeta. These findings further support the idea that these enzymes form a protein family both within and across species. Eighteen contigs for PLDs were found for L. gaucho, 24 for L. intermedia, and 21 for L. laeta. A detailed analysis revealed that, although all contigs display conserved amino acid residues directly involved in catalysis, magnesium coordination, and substrate affinity, they also possess distinct primary sequences with important substitutions. Such data reinforces the hypothesis that these toxins may act synergistically. Furthermore, new PLD sequences were identified within the contigs. For L. intermedia, 14 potential new isoforms were identified; 16 for L gaucho; and 16 novel sequences for L. laeta. This indicates that there is still a wealth of undisclosed information about these toxins. These data will help identify structural and functional differences among these proteins, support future functional studies, and to the comprehensive understanding of the mechanism of action of PLDs., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Silvio Sanches Veiga reports financial support was provided by National Council for Scientific and Technological Development- Brazil.

- Abstract
We report a 9-year-old girl with delayed motor milestones and respiratory difficulty since birth. She presented as a floppy infant, with generalised muscle wasting, dysphagia and facial weakness. The muscle biopsy of the biceps brachii revealed congenital fibre-type disproportion (CFTD) and Sanger sequencing detected a pathogenic variant in the beta-tropomyosin (TPM2) gene (c.415_417delGAG; p.Glu139del). There has been only one previous report of CFTD associated with p.Glu139del in the TPM2 gene., (© 2024. Fondazione Società Italiana di Neurologia.)

- Abstract
Background: Mindfulness-based cognitive therapy (MBCT) includes regular home practice of mindfulness exercises as a key means of cultivating mindfulness. Although there are instruments available for measuring homework adherence following cognitive behavioral therapy (CBT), little is known about measuring homework practice in MBCT studies for sexual dysfunction., Aim: In this review we sought to investigate which items and instruments are the most used for the assessment of homework adherence in studies evaluating MBCT for the treatment of female sexual dysfunction (FSD). We also investigated the types of homework used in these interventions., Methods: Five databases (PubMed, Scopus, PsycINFO, Embase, and Web of Science) were searched and a total of 30 articles were included in this review., Outcomes: Our main findings revealed that there was no gold standard instrument used to assess homework adherence in patients using MBCT interventions for FSD, and that most of the reported studies did not provide information on how they assess homework adherence., Results: Six of the 9 studies for which the articles reported how homework was assessed used only ad hoc measures. Only 3 studies used psychometrically validated instruments. We also found that mindfulness, psychoeducation, and CBT exercises were the most prescribed homework., Strengths and Limitations: This review uniquely integrates homework adherence measures with studies on FSD that evaluate mindfulness, finding no gold standard for assessing adherence. However, limitations including both MBCT and CBT interventions, limiting generalization to MBCT alone, the predominance of Western-based studies, and the lack of reporting on instruments used to assess adherence, indicating a gap in the field., Conclusion: Further studies should consider adapting existing instruments that assess homework adherence in studies of CBT for other psychopathologies or seek to develop new psychometrically validated instruments for MBCT interventions that assess homework adherence., (© The Author(s) 2024.

- Abstract
Patients with peripheral artery disease and generalized atherosclerosis are at high risk of cardiovascular and limb complications, affecting both quality of life and longevity. Lower limb atherosclerotic disease is associated with high cardiovascular morbidity and mortality and adequate management is founded on treatments involving patient-dependent factors, such as lifestyle changes, and physician-dependent factors, such as clinical treatment, endovascular treatment, or conventional surgery. Medical management of peripheral artery disease is multifaceted, and its most important elements are reduction of cholesterol level, antithrombotic therapy, control of arterial blood pressure, control of diabetes, and smoking cessation. Adhesion to this regime can reduce complications related to the limbs, such as chronic limb-threatening ischemia, that can result in amputation, and the systemic complications of atherosclerosis, such as stroke and myocardial infarction., Competing Interests: Conflicts of interest: No conflicts of interest declared concerning the publication of this article., (Copyright© 2024 The authors.)

- Abstract
Brycon amazonicus is a species native to Brazil, with significant socioeconomic importance and immense potential for fish production. It is the second most cultivated species in the Amazon. The lack of specific molecular markers limits genetic research. This study aimed to identify species-specific microsatellite markers for B. amazonicus and analyze the genetic diversity of four fish farms: Nova Mutum, Instituto Nacional de Pesquisa da Amazônia, Jatuarana, and Nova Airão. In addition, the transferability of these markers to species of the same genus (B. orbignyanus, B. falcatus, and B. gouldingi) was evaluated. Seventeen primer pairs were developed using the enriched library method. Eight of these were used for the genetic analysis of B. amazonicus stocks. In total, 47 alleles were identified. The mean endogamy coefficient (FIS) was negative and significant for Nova Mutum stocks. However, the populations of B. amazonicus in Instituto Nacional de Pesquisa da Amazônia (0.179), Jatuarana (0.099), and Nova Airão were positive and nonsignificant. Analysis of molecular variance showed that most of the variation was observed within the populations evaluated (57%), and genetic differentiation (FST = 0.423) among the stocks was high. Bayesian analysis indicated that the best number of genetic clusters was K = 3. Transferability testing showed successful amplification (90%) of the primers by estimating the allele size between 144 and 294 base pairs (bp) and a total of 24 alleles for the related Brycon species. This indicates the high potential of microsatellites for the analysis of diversity and population genetic structure in both the genus Brycon and family Characidae.

- Abstract
The PII signaling proteins are ubiquitous in prokaryotes serving as crucial metabolic hubs in different metabolic pathways due to their ability to sense and integrate signals of the cellular nitrogen, carbon, and energy levels. In this study we used ligand fishing assays to identify the ribonucleotide monophosphatase UmpH enzyme as a novel target of the PII signaling protein GlnK in Escherichia coli. In vitro analyses showed that UmpH interacts specifically with the PII protein GlnK but not with its paralogue protein GlnB. The UmpH - GlnK complex is modulated by the GlnK uridylylation status and by the levels of the GlnK allosteric effectors ATP, ADP and 2-oxoglutarate. Upon engaging interaction with GlnK, UmpH becomes less active towards its substrate uridine 5'-monophosphate (UMP). We suggest a model where GlnK will physically interact to reduce the UmpH activity during the transition from N-starvation to N-sufficient conditions. Such a mechanism may help the cells to reprogram the fate of UMP from catabolism to anabolism avoiding futile cycling of key nutrients., (Copyright © 2024 The Authors. Published by Elsevier Inc.

- Abstract
Objectives: Recently, tissue motion annular displacement by speckle tracking has been shown to be a reliable method for evaluating deformation of the left atrium in healthy dogs. The aim of this study was to investigate whether tissue motion annular displacement is a feasible alternative method for studying left atrial function., Materials and Methods: One hundred healthy dogs were included. Left atrial function was assessed by tissue motion annular displacement, which was correlated to the left atrial strain and biplane area-length method-derived volumes. Left atrial reservoir function was evaluated by left atrial global tissue motion annular displacement, global left atrial strain and left atrial emptying fraction, while left atrial systolic tissue motion annular displacement and left atrial ejection fraction were used to assess left atrial systolic function., Results: A statistically significant association between body weight and the dependent variables others than age was found. Indexed global and systolic tissue motion annular displacement decreased as body weight increased. Global iTMAD_AIIometric (mm/∛kg) showed a moderate, positive correlation with left atrial emptying fraction and with global left atrial strain. Systolic iTMAD_AIIometric (mm/∛kg) showed a moderate correlation with left atrial ejection fraction. Coefficients of variation for the intraobserver and interobserver analyses were 8.3% and 20.3% for global and 10.5% and 18.9% for systolic tissue motion annular displacement, respectively., Clinical Significance: Tissue motion annular displacement is a feasible and simple method for the evaluation of left atrial function. Our study documented the effects of body weight on left atrial tissue motion annular displacement, indicating that tissue motion annular displacement must be indexed to body weight. No influence of age or heart rate was observed on tissue motion annular displacement., (© 2024 British Small Animal Veterinary Association.)

- Abstract
Coastal areas are affected by urban, industrial and agriculture pollutants runoff, wastewater and stormwater discharges, making this environment the final repository of chemical contaminants. These contaminants have the potential to spread out to the entire food chain, impacting marine life and the quality of their habitat. In this aspect, the concept of marine mammals as bioindicators provides an approach to the degree of contamination in the environment and to the identification and management of multiple sources of contaminants. The present study analyzed several elements like As, Ba, Cd, Cr, Cu, Hg, Mn, Mo, Ni, Pb, V and Zn in liver tissue from two dolphin species: Sotalia guianensis, a near-threatened species, and the vulnerable Pontoporia blainvillei. In the study, we also investigated if dolphins (population) recorded using the heaviest urban areas have higher concentrations of contaminants in their tissues. Dolphin samples (n = 40 S. guianensis; n = 97 P. blainvillei) were collected by daily monitoring carried out by Santos Basin Beach Monitoring Project (PMP-BS), from stranded individuals found in São Paulo state. The Spearman's rank correlation showed distinct correlations in the accumulation of trace elements by both species, indicating different sources of exposure to the elements studied or distinct biochemical processes between species. Interspecific and intraspecific variations were observed, possibly related to the individual distribution and feeding habits. Correlations were observed between age and concentrations of trace elements, positive for Cd, Hg and Mo. Finally, our findings indicate high levels of Cu, Zn, and concentrations of As, V and Hg in fetuses, in particular, an analysis was performed on a fetus found inside a stranded individual, indicating placental transfer as the first route of exposure for some elements., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

- Abstract
Background: Recent studies have highlighted the multifactorial nature of bruxism, with behavioral, psychosocial, and physiological factors, including genetic predisposition, contributing to its development. However, the role of genetic markers in determining susceptibility to bruxism remains poorly understood, with limited studies offering significant findings., Objectives: To identify the current knowledge to investigate the susceptibility of genetic markers for sleep (SB) and/or awake bruxism (AB)., Materials and Methods: Seven electronic databases and two grey literature platforms were searched up to January 2024. We included studies that related different types of genes and/or genetic polymorphisms with different types of bruxism, regardless of age or sex of the participants. To be included the study must have described the form of detection of bruxism., Results: A total of 21 reports were included. Of these, 16 were primary research reports. The remaining five articles consisted of four systematic reviews and a literature review incorporating a systematic mapping process, and network visualization. Within the pool of 16 primary study reports, seven focused on the association of genetic polymorphisms with both SB and AB, while seven concentrated solely on the association with SB. One primary study reported results related to probable AB and one article did not specify the bruxism type. Regarding all the studied genes and polymorphisms, significant association results were obtained for 15 polymorphisms from 11 different genes. Self-reported SB was associated with genes from the serotonergic (5HTR2A) and dopaminergic pathways (DRD2, DRD3, and ANKK1), as well as genes encoding enzymes (COMT and MMP9) and proteins (ACTN3 and ANKK1). Instrumentally reported SB was linked only to the reverse telomerase gene (TERT). Self-reported AB was associated with the ACTN3 and ANKK1 genes., Conclusion: This review identified 30 genes and 56 polymorphisms variations potentially associated with either SB or AB. However, few presented significant results regarding positive associations, mostly acting at neurotransmitter pathways. The authors recommend further studies to determine the susceptibility of genetic markers as a risk factor for bruxism., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Julia Meller Dias de Oliveira reports financial support was provided by Foundation for Research Support and Innovation of Santa Catarina State. Manuella Salm Coelho, Graziela De Luca Canto, and Eliete Neves Silva Guerra reports financial support was provided by National Council for Scientific and Technological Development.

- Abstract
Hemotropic mycoplasmas, also known as hemoplasmas, are found in several animal species around the world. New species and genotypes of mycoplasmas have been described recently but much more remains to be discovered, especially in wildlife. The objective of this study was to investigate the presence of hemotropic mycoplasmas and diversity of the 16S rDNA sequence fragment in populations of small nonflying mammals in regions with different phytophysiognomies in the states of Rio de Janeiro and Parana, Brazil, as well as to evaluate environmental and animal factors influencing infection rates. Of the 257 animals sampled, 33.8 % (n = 87) were considered positive by conventional PCR. Of the 230 samples from wild rodents (Cricetidae), 36.5 % (n = 84) amplified hemotropic mycoplasma DNA, followed by synanthropic rodents (Muridae) (12.5 %, n = 2/16), and marsupials (Didelphidae) (9.0 %, n = 1/11). The regions with the highest frequency of positivity were Ponta Grossa (46.5 %, n = 27/58) and Cruz Machado (46.1 %, n = 24/52), followed by Nova Friburgo (30.8 %, n = 33/107), and Lidianopolis (12.5 %, n = 5/40). Oligoryzomys had the highest rate of infection (78.5 %), statistically different from Oxymycterus spp. (40.0 %), Akodon spp. (27.0 %) and Sooretamys (8.3 %). Males had a higher prevalence of Mycoplasma spp., being 3.97 times more likely to be positive for hemoplasma than females. Phylogenetic analysis grouped the sequences from this study into two clades, A and E, together with other hemoplasma sequences previously detected in small wild and synanthropic rodents from Brazil, Hungary, and Japan. Haplotype network reveals exclusive haplotypes for wild and synanthropic rodents. Our study reveals considerable genetic diversity suggesting the circulation of at least two species among sequences from this study and highlights the importance of considering environmental and biological factors in the epidemiology of these infections in wild mammals., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Introduction: Bilateral cleft lip (BCL) repair is a challenge due to anatomic and functional distortions, worse than unilateral cleft. With regard to the nose, BCL can result in certain characteristics, such as a short columella, a flattened and widened tip, and horizontally oriented nostrils. Lip and nose treatment is advocated by some surgeons to achieve a better outcome. One of the techniques used to treat this condition is the one recommended by Victor Spina, in a complex protocol involving more than one surgical procedure and long-term follow-up. The aim of this study is to evaluate the growth of the nose in patients treated using the Spina technique., Materials and Methods: This was a retrospective and analytical study of the medical records of patients who were treated using the Spina technique at the Assistance Center for Cleft Lip and Palate (CAIF) at Hospital do Trabalhador in Curitiba, Brazil. Anthropometric measurements of interalar distance and nose tip projection were made from frontal and submental photographs taken at three moments: pre-first surgery, pre-definitive surgery, and late follow-up. Furthermore, other analyzed parameters were: sex, date of birth, age at time of surgery, and late follow-up. With these data, a comparison of nose growth was made between patients with BCL and a population without craniofacial anomalies observed in a study by FARKAS et al (1992). The comparison also took sex and age variables into account., Results: Regarding the interalar distance measurements, both sexes showed a widening of the nose before starting treatment. This widening was maintained throughout follow-up. The growth curve, in turn, remained similar among males, with an average growth rate of only 3.2% higher in patients with BCL. Among females, the difference was one of 16.92%. In terms of nasal tip projection, there was an average increase of 1.12 cm (86.15%) in males and 0.69 cm (57.02%) in females., Conclusion: It was possible to notice a nasal growth rate in those with BCL similar to the normal pattern and a significant improvement in nasal tip projection in male patients. However, with regard to the data of both sexes, but especially females, the low number of patients jeopardized the significance of the results., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 by Mutaz B.

- Abstract
Fridericia chica is widely distributed in Brazil, where it is commonly known as crajiru or pariri in several regions. Despite its popular use for treating inflammations and as an insect repellent, there has been limited assessment of its chemical and biological properties, including its bioinsecticide activities. In this study, we conducted phytochemical analyses and investigated the larvicidal and repellent effects of F. chica against the mosquito Aedes aegypti. The F. chica (HEFc) hydroalcoholic extract was partitioned using column chromatography, and subfractions were analyzed using chromatographic and spectroscopic analyses (ESI-IT-MS
n and NMR). In addition, HEFc was evaluated for its larvicidal and repellent activities. Phytochemical analyses revealed the presence of 17 constituents, including 2,4-dihydroxybenzoic and p-coumaric acids, along with umbelliferone, acetovanilone, myricetin-3-O-glucuronide, and cis-isorhapontigenin, which are reported for the first time in this species. Although no larvicidal effect was observed at the doses tested, the HEFc exhibited promising repellent effects against A. aegypti, which aligns with its ethnopharmacological potential. In addition, molecular docking studies demonstrated that the compounds of HEFc interacted efficiently with insect odorant binding proteins (OBPs), providing repellent effects. Consistent with the chemical profile and in silico studies, preparations of F. chica have considerable repellent potential., (© 2024 Wiley-VHCA AG, Zurich, Switzerland.)- Published

- Abstract
The nervous system is rich in miRNAs, indicating an important role of these molecules in regulating processes associated with cognition, memory, and others. Therefore, qualitative and quantitative imbalances involving such miRNAs may be involved in dementia contexts, including Late-Onset Alzheimer's Disease (LOAD). To test the viability of circulating miRNAs (c-miRNAs) as biomarkers for LOAD, we proceed accordingly to the following reasoning. The first stage was to discover and identify profile of c-miRNAs by RNA sequencing (RNA-Seq). For this purpose, blood serum samples were used from LOAD patients (n = 5) and cognitively healthy elderly control group (CTRL_CH) (n = 5), all over 70 years old. We identified seven c-miRNAs differentially expressed (p ≤ 0.05) in the serum of LOAD patients compared to CTRL_CH (miR-10a-5p; miR-29b-2-5p; miR-125a-5p; miR-342-3p, miR-708-5p, miR-380-5p and miR-340-3p). Of these, five (p ≤ 0.01) were selected for in silico analysis (miR-10a-5p; miR-29b-2-5p; miR-125a-5p; miR-342-3p, miR-708-5p), for which 44 relevant target genes were found regulated by these c-miRNAs and related to LOAD. Through the analysis of these target genes in databases, it was possible to observe that they have functions related to the development and progress of LOAD, directly or indirectly connecting the different Alzheimer's pathways. Thus, this work found five promising serum c-miRNAs as options for biomarkers contributing to LOAD diagnosis. Our study shows the complex network between these molecules and LOAD, supporting the relevance of studies using c-miRNAs in dementia contexts., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Schmidt A, Pereira AF, and Zarbin AJG
- Abstract
The nanostructured assembly of different two-dimensional (2D) materials in specific organization is crucial for developing materials with synergistic properties. In this study, we present a general methodology to prepare thin, transparent and self-assembled films of 2D/2D composites based on molybdenum sulfide (MoS
2 )/graphene oxide (GO) or MoS2 /reduced graphene oxide (rGO), through the liquid/liquid interfacial route. Different nanoarchitectures are obtained by changing simple experimental parameters during the thin film preparation steps. The films were characterized by UV-Vis and Raman spectroscopy, scanning electron microscopy and cyclic voltammetry, evidencing that the experimental route used plays a role in the organization and properties of the assembled nanoarchitectures. Likewise, nanostructures of MoS2 /GO and MoS2 /rGO prepared through the same route have different organizations due to the different interactions between the materials. This showcases the potential of the technique to prepare tailored nanoarchitectures with specific properties for various applications, paving the way for innovative nanotechnology and materials science applications., (© 2024 Wiley-VCH GmbH.)- Published

- Abstract
Introduction: Infectious diseases can spread rapidly in the globalized world, and the complex intersection of individual, social, economic, and cultural factors make it difficult to identify vulnerabilities in the face of pandemics., Methods: Therefore, this study aimed to identify vulnerability factors to infection and worse outcomes associated with COVID-19. This is a scoping review study of six databases that selected publications between 2019 and 2023, focusing on individual, social, and programmatic dimensions of vulnerability. The results were recorded in a spreadsheet and analyzed, considering the interrelationships among these dimensions., Results: A total of 45 articles were included in the review. Content analysis was conducted using the theoretical framework of health vulnerability, which divides vulnerability into individual, social, and programmatic dimensions. Race/ethnicity, homelessness, incarceration, socioeconomic level, food insecurity, and remote areas were classified as social dimensions. On the other hand, cancer, cardiovascular disease, HIV/AIDS, alcoholism, advanced age, obesity, mental disorders, diabetes, kidney disease, and pregnancy were classified as individual dimensions. None of the publications found explicitly mentioned programmatic vulnerabilities., Discussion: The research found that social vulnerabilities reinforce individual vulnerabilities, creating a vicious cycle. In addition, programmatic vulnerabilities reinforce this relationship. This study emphasizes that public policies should address these different dimensions of vulnerability. It suggests that this information should be incorporated into health surveillance and future decision-making to face new pandemics., Systematic Review Registration: https://archive.org/details/osf-registrations-wgfmj-v1., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Couto, dos Santos, Sanine, Pires dos Santos, Kmetiuk, Biondo and Boing.)

- Abstract
This study evaluated the passion fruit peel biochar (PFPB) as a novel adsorbent for synthetic food dyes indigotine blue (IB), tartrazine yellow (TY), and ponceau 4R (P4R) removal in single and ternary systems. A macroporous structure and a predominance of basic groups characterized PFPB. The pH study revealed better adsorption at pH 2.0. The response surface methodology optimization for adsorbent dosage and temperature predicted removal efficiencies of 100 % for IB, 79.8 % for TY, and 84.4 % for P4R. Elovich and Redlich-Peterson models better described kinetic and equilibrium, respectively, suggesting the contribution of chemical interactions. Thermodynamic data revealed endothermic, with an inordinate degree and spontaneous adsorption. In the ternary systems, antagonistic effects of interaction were noticed. The adsorption of synthetic effluents showed promising results with removal efficiencies of 99.6 % (IB), 60.2 % (TY), and 51.8 % (P4R). Therefore, we concluded that PFPB is a potential alternative low-cost synthetic food dye removal adsorbent., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Bender D and Aguiar LM
- Abstract
Capuchin monkeys are omnivorous platyrrhines with a high frequency of faunivory and can survive in urban forest fragments. Predation of wild vertebrates (high-quality foods) by capuchin monkeys has been frequently reported in many species of Cebus and Sapajus. However, predation of domestic animals is unknown. We describe a rare episode of predation, consumption, and sharing of an adult domestic chicken (Gallus gallus domesticus) by individuals from a social group of robust capuchin monkeys (Sapajus sp.) living in a small urban park in the city of Foz do Iguaçu, southern Brazil. This relatively large prey is freely farmed at the study site. The capture, slaughter, preparation (removal of feathers from the body), and consumption of the prey by the capuchins lasted 22 min. The dominant adult male ate the chicken's head and tolerated the approach of two juveniles. The juveniles shared the remainder of the prey after the adult abandoned it. These juveniles scared other group members that approached the carcass. We recorded an opportunistic hunt for easily accessible domestic prey, a case of human resource use by urban primates that shared passively the atypical and valuable food. Though a rare event, the predation on a domestic animal indicates a potential source of conflict with humans that can have negative impacts on urban primates., (© 2024.

- Abstract
(1) Background: After the COVID-19 pandemic, there is concern regarding the immunity of the population to SARS-CoV-2 variants, particularly the Omicron variant and its sub-lineages. (2) Methods: The study involved analyzing the immune response and symptomatology of 27 vaccinated individuals who were subsequently infected by Omicron sub-lineages. Blood samples were collected for serological analysis, including the detection of IgG antibodies reactive to the Nucleocapsid (N) and Spike (S) antigens of SARS-CoV-2. Additionally, participants were interviewed to assess the intensity of symptoms during the infection. (3) Results: Despite the high levels of anti-Spike IgG observed after vaccination, all participants were infected by Omicron sub-lineages. The most common symptoms reported by participants were fever or chills, sore throat, and cough. The levels of anti-Spike IgG found prior to infection did not correlate with symptom intensity post-infection. However, it was observed that high post-infection anti-Nucleocapsid IgG levels correlated with mild symptoms during the course of the disease, suggesting a potential role for anti-N antibodies in symptom intensity. (4) Conclusions: In line with previous studies, the high levels of IgG anti-Spike resulting from vaccination did not provide complete protection against infection by the Omicron variant. Additionally, our data suggest that anti-Nucleocapsid IgG titers are negatively correlated with the intensity of the symptoms during mild infections.

Junges LH and Müller-Santos M
- Abstract
Tryptamines play diverse roles as neurotransmitters and psychoactive compounds found in various organisms. Psilocybin, a notable tryptamine, has garnered attention for its therapeutic potential in treating mental health disorders like depression and anxiety. Despite its promising applications, current extraction methods for psilocybin are labor-intensive and economically limiting. We suggest biocatalysis as a sustainable alternative, leveraging enzymes to synthesize psilocybin and other tryptamines efficiently. By elucidating psilocybin biosynthesis pathways, researchers aim to advance synthetic methodologies and industrial applications. This review underscores the transformative potential of biocatalysis in enhancing our understanding of tryptamine biosynthesis and facilitating the production of high-purity psilocybin and other tryptamines for therapeutic and research use., (© 2024 American Institute of Chemical Engineers.)

- Abstract
Background: Nuts consumption is related to cardioprotective effects on primary cardiovascular prevention, but studies conducted in secondary prevention are small, scarce and controversial. The objective of this trial was to evaluate the effects of a regional and sustainable cardioprotective diet added or not with an affordable mixed nuts on cardiometabolic features in patients with previous myocardial infarction., Methods: DICA-NUTS study is a national, multi-center, and superiority-parallel randomized clinical trial. Males and females over 40 years old diagnosed with previous myocardial infarction in the last 2 to 6 months were included. Patients were allocated into two groups: the Brazilian Cardioprotective diet (DICA Br) supplemented with 30 g/day of mixed nuts (10 g of peanuts; 10 g of cashew; 10 g of Brazil nuts) (intervention group, n = 193); or only DICA Br prescription (control group, n = 195). The primary outcome was low-density lipoprotein cholesterol means (in mg/dL) after 16 weeks. Secondary outcomes were other lipid biomarkers, glycemic and anthropometric data and diet quality., Results: After adjustment for baseline values, participating study site, time since myocardial infarction and statin treatment regimen (high potency, moderate and low potency/no statins), no significant difference was found between the groups in low-density lipoprotein cholesterol concentrations (intervention-control difference: 3.48 mg/dL [-3.45 to 10.41], P = 0.32). Both groups improved their overall diet quality at the end of the study without differences between them after 16 weeks (intervention-control difference: 1.05 (-0.9 to 2.99); P = 0.29). Other lipids, glycemic profile and anthropometrics were also not different between study groups at the end of the study., Conclusion: Adding 30 g/day of mixed nuts to the DICA Br for 16 weeks did not change lipid, glycemic and anthropometric features in the post-myocardial infarction setting., Trial Registration: This study is registered on ClinicalTrials.gov website under number NCT03728127 and its World Health Organization Universal Trial Number (WHO-UTN) is U1111-1259-8105., (© 2024.

- Abstract
Background: Progressive disseminated histoplasmosis is a significant issue in Latin America, particularly in Brazil, contributing to high mortality rates., Objectives: Our objectives were to comprehensively describe histoplasmosis treatment with various amphotericin B (AmB) formulations, including mortality rates, adverse effects and risk factors for mortality., Methods: This multicentre retrospective cohort study (January 2014-December 2019) evaluated medical records of patients with proven or probable histoplasmosis treated with at least two doses of AmB in seven tertiary medical centres in Brazil. We assessed risk factors associated with death during hospitalization using univariate and multivariate analyses., Results: The study included 215 patients, mostly male (n = 158, 73%) with HIV infection (n = 187, 87%), and a median age of 40 years. Only 11 (5%) patients initiated treatment with liposomal amphotericin B (L-AmB). Amphotericin B deoxycholate (D-AmB) was administered to 159 (74%) patients without changes in the treatment. The overall mortality during hospitalization was 23% (50/215). Variables independently associated with mortality were use of D-AmB (OR 4.93) and hospitalization in ICU (OR 9.46). There was a high incidence of anaemia (n = 19, 90%), acute kidney injury (n = 96, 59%), hypokalaemia (n = 73, 55%) and infusion reactions (n = 44, 20%) during treatment., Conclusions: We found that D-AmB was the main formulation, which was also associated with a higher mortality rate. Lipid formulations of AmB have become more readily available in the public health system in Brazil. Further studies to evaluate the effectiveness of L-AmB will likely show improvements in the treatment outcomes for patients with disseminated histoplasmosis., (© The Author(s) 2024.

- Abstract
DNA barcoding and environmental DNA (eDNA) represent significant advances for biomonitoring the world's biodiversity and its threats. However, these methods are highly dependent on the presence of species sequences on molecular databases. Brazil is one of the world's largest and most biologically diverse countries. However, many knowledge gaps still exist for describing, identifying, and monitoring of mammalian biodiversity using molecular methods. We aimed to unravel the patterns of the presence of Brazilian mammal species on molecular databases to improve our understanding of how effectively it would be to monitor them using DNA barcoding and environmental DNA, and contribute to mammalian conservation. We foundt many gaps in molecular databases, with many taxa being poorly represented, particularly from Amazonia, the order Lagomorpha, and arboreal, gomivorous, near extinct, and illegally traded species. Moreover, our analyses revealed that species description year was the most important factor determining the probability of a species to being sequenced. Primates are the group with the highest number of species considered a priority for sequencing due to their high level of combined threats. We highlight where investments are needed to fill knowledge gaps and increase the representativity of species on molecular databases to enable a better monitoring ability of Brazilian mammals encompassing different traits using DNA barcoding and environmental DNA., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Hernani Fernandes Magalhaes de Oliveira reports financial support was provided by Coordenação de Aperfeiçoamento de Ensino Superior (CAPES).

- Abstract
Loxoscelism is the pathological condition triggered by a brown spider bite. The venom of these spiders is rich in phospholipases D (PLDs), which can induce virtually all local and systemic manifestations. Recombinant mutated PLDs from clinically relevant Loxosceles species in South America have been investigated as potential antigens to develop novel therapeutic strategies for loxoscelism. However, certain gaps need to be addressed before a clinical approach can be implemented. In this study, we examined the potential of these recombinant mutated PLDs as antigens by testing some variations in the immunization scheme. Furthermore, we evaluated the efficacy of the produced antibodies in neutralizing the nephrotoxicity and sphingomyelinase activity of brown spider venoms. Our findings indicate that the number of immunizations has a greater impact on the effectiveness of neutralization compared to the amount of antigen. Specifically, two or three doses were equally effective in reducing dermonecrosis and edema. Additionally, three immunizations proved to be more effective in neutralizing mice lethality than one or two. Moreover, immunizations mitigated the signs of kidney injury, a crucial aspect given that acute renal failure is a serious systemic complication. In vitro inhibition of the sphingomyelinase activity of Loxosceles venoms, a key factor in vivo toxicity, was nearly complete after incubation with antibodies raised against these antigens. These findings underscore the importance of implementing an effective immunization scheme with multiple immunizations, without the need for high antigen doses, and enhances the spectrum of neutralization exhibited by antibodies generated with these antigens. In summary, these results highlight the strong potential of these antigens for the development of new therapeutic strategies against cutaneous and systemic manifestations of loxoscelism., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Silvio Sanches Veiga reports financial support was provided by National Council for Scientific and Technological Development.

- Abstract
Objective: To estimate original wild-type BNT162b2 effectiveness against symptomatic Omicron infection among children 5-11 years of age., Methods: This prospective test-negative, case-control study was conducted in Toledo, southern Brazil, from June 2022 to July 2023. Patients were included if they were aged 5-11 years, sought care for acute respiratory symptoms in the public health system, and were tested for SARS-CoV-2 using reverse transcription polymerase chain reaction. In the primary analysis, we determined the effectiveness of two doses of original wild-type BNT162b2 against symptomatic COVID-19. The reference exposure group was the unvaccinated., Results: A total of 757 children were enrolled; of these, 461 (25 cases; 436 controls) were included in the primary analysis. Mean age was 7.4 years, 49.7 % were female, 34.6 % were obese, and 14.1 % had chronic pulmonary disease. Omicron accounted for 100 % of all identified SARS-CoV-2 variants with BA.5, BQ.1, and XBB.1 accounting for 35.7 %, 21.4 % and 21.4 %, respectively. The adjusted estimate of two-dose vaccine effectiveness against symptomatic Omicron was 3.1 % (95 % CI, -133.7 % to 61.8 %) after a median time between the second dose and the beginning of COVID-19 symptoms of 192.5 days (interquartile range, 99 to 242 days)., Conclusion: In this study with children 5-11 years of age, a two dose-schedule of original wild-type BNT162b2 was not associated with a significant protection against symptomatic Omicron infection after a median time between the second dose and the beginning of COVID-19 symptoms of 192 days, although the study may have been underpowered to detect a clinically important difference., Trial Registration Number: ClinicalTrials.gov number, NCT05403307 (https://classic., Clinicaltrials: gov/ct2/show/NCT05403307)., Competing Interests: Declaration of competing interest Rodrigues, Maltempi de Souza, Manfio, de Souza, Araujo, Cohen, Barbosa, Romeiro Silva, Sganzerla, Dias da Silva, Ferreira, Kunkel, Camargo, Sarturi, Guilhem, Oliveira, Lopes, Widmar, Barufi, Nunes da Silva, Gradia, Brandalize, Royer, Luiz, Baura, Abreu, and Poitevin report honoraria fee for working in this study from Hospital Moinhos de Vento.

- Abstract
Objectives: To assess the impact of the COVID-19 pandemic on disability insurance grants and related costs for workers with cancer., Methods: This ecological time series study uses the inflection point regression model and the federal government's open-access dataset. We analyze the annual grant and cost rates of cancer-related disability insurance in Brazil (2010-2021)., Results: In 2020, the number of disability insurance grants due to malignant neoplasms decreased by 62.26%, and the total annual cost decreased by 62.94% compared to those in 2019. All illnesses and injuries were reduced by 2.56% and 20.02%, respectively. Between 2010 and 2021, the COVID-19 pandemic has reversed the increasing trend in annual disability insurance granted due to cancer and its associated expenses to a stable trend., Conclusion: The COVID-19 pandemic has harmed the provision of disability insurance for workers with cancer., Competing Interests: Declaration of Conflicting Interests: The authors declared no potential conflicts of interest concerning this article's research, authorship, and publication., (Copyright © 2024 American College of Occupational and Environmental Medicine.)

- Abstract
Objective: Provide a synthesis of the current literature about the effects of detraining on cognitive functions in older adults., Methods: The PICOS acronym strategy was performed in PubMed/MEDLINE, Web of Science, Cochrane Library and PsycINFO database. The Preferred Reporting Items for Systematic Review and Meta-Analyses statement had been followed in the present study, in which the search was conducted on October 2023. The study selection consisted in original articles including older adults, detraining after training exercise period, use of tests or scales to measure cognitive function. The Downs and Black checklist had been used to assess the studies quality. Sample characteristics, type of previous training, detraining period, cognitive functions measurements and main results were extracted by 2 investigators., Results: From 1927 studies, 12 studies were included, being 11 studies identified via systematic research, and 1 study by citation search. Older adults, ranged from 60 to 87 years old, were assessed after detraining. The cognitive functions most evaluated were global cognition and executive functions. One study evaluated both cognitive outcome and cerebral blood flow. Most of the studies demonstrated a decline in the cognitive function after detraining., Conclusion: Exercise detraining period, ranging from 10 days to 16 weeks, can effect negatively the cognitive function in older adults., Competing Interests: Declaration of competing interest On behalf of all co-authors, I declare no conflict of interest in the manuscript titled “Effect of exercise detraining in cognitive functions of older adults: a systematic review”. In the manuscript file (anonymized) the same declaration was described. Angelica Miki Stein, PhD, (Copyright © 2024 Elsevier B.V. All rights reserved.)
