Modified Procedure for Simple and Rapid Collection of Zebrafish Fluid Samples for Biochemical Analyses.

This study addresses the challenge of collecting blood samples from zebrafish for biochemical analysis. Traditional methods are cumbersome due to low blood flow and rapid coagulation. Based on a previously published technique, we simplified the process by applying an anticoagulant solution directly to the incision site. The modified protocol involves immersing the fish in an ice bath, making a cross-sectional incision, and immediately applying anticoagulant solution. Centrifugation of the specimens provides a streamlined and efficient approach to zebrafish fluid sample collection, compatible with classic biochemical marker analyses.

Congo red induces trans-priming to UV-B radiation in Metarhizium robertsii.

Metarhizium spp. is used as a biocontrol agent but is limited because of low tolerance to abiotic stress. Metarhizium robertsii is an excellent study model of fungal pathogenesis in insects, and its tolerance to different stress conditions has been extensively investigated. Priming is the time-limited pre-exposure of an organism to specific stress conditions that increases adaptive response to subsequent exposures. Congo red is a water-soluble azo dye extensively used in stress assays in fungi. It induces morphological changes and weakens the cell wall at sublethal concentrations. Therefore, this chemical agent has been proposed as a stressor to induce priming against other stress conditions in entomopathogenic fungi. This study aimed to evaluate the capacity of Congo red to induce priming in M. robertsii. Conidia were grown on potato dextrose agar with or without Congo red.The tolerance of conidia produced from mycelia grown in these three conditions was evaluated against stress conditions, including osmotic, oxidative, heat, and UV-B radiation. Conidia produced on medium supplemented with Congo red were significantly more tolerant to UV-B radiation but not to the other stress conditions assayed. Our results suggest that Congo red confers trans-priming to UV-B radiation but not for heat, oxidative, or osmotic stress.

Human immunodeficiency virus epidemic scenery among brazilian women: a spatial analysis study.

BACKGROUND: Approximately 37.7 million people worldwide are infected with human immunodeficiency virus (HIV). Although HIV detection among women, they still representing 53% of population living with the virus. Spatial analysis techniques are powerful tools for combating HIV allowing the association of the phenomenon with socioeconomic and political factors. Therefore, the main goal of this study was to spatially analyze HIV prevalence among Brazilian women from 2007 to 2020. METHODS: ecological study was conducted using secondary databases of the Notifiable Diseases Information System (SINAN) for HIV and Acquired Immunodeficiency Syndrom (AIDS) in Brazilian women 15 years old and over. Age-adjusted HIV/AIDS incidence rates were analyzed using spatial distribution, autocorrelation, and spatiotemporal risk analysis techniques. RESULTS: During the study period, 119,890 cases of HIV/AIDS were reported among Brazilian women. The southeastern region had a higher age-adjusted HIV/AIDS incidence than other Brazilian regions. Hotspot HIV/AIDS incidence rates decreased in all Brazil. Piauí, Paraná, and Minas Gerais were the only states with an increased number of cold spots. Previous spatiotemporal risk zones were observed in the states of São Paulo, Rio Grande do Sul, and Rio de Janeiro. Belém was a risk zone with a later spatiotemporal risk. CONCLUSIONS: The efficiency of public policies fighting HIV has not been uniform among municipalities, although HIV/AIDS cases have decreased among Brazilian women. The social determinants of health in each municipality should be considered when local health authorities implement policies. Women empowerment should be promoted, and access to preventive, diagnostic, and treatment healthcare places should be expanded and guaranteed.

Is silver diamine fluoride effective in reducing dentin hypersensitivity? A systematic review.

Background: The purpose of this systematic review was to assess the clinical efficacy (sensitivity reduction) and safety (gum damage) of silver diamine fluoride (SDF) as a tooth desensitizer for adults. Methods: The search strategy was developed and adapted from 12 databases. Two independent reviewers selected the studies in consensus with a third reviewer. Randomized clinical trials with adult volunteers affected by dentin hypersensitivity (DH), and receiving treatment with SDF were included. Studies with volunteers testing tooth whitening products, using some type of desensitizer, or taking analgesic or anti-inflammatory medication were excluded. The risk of bias was assessed according to the RoB 2 tool, and confidence in cumulative evidence, according to GRADE. Results: Only 3 articles were included. The average pain assessed using the visual analog scale was lower in the SDF groups than in the short-term control groups (24h to 7 days) (P=0.0134 and P=0.0015) of the two studies. The third study evaluated a combination of SDF and a CO2 laser, compared to using only SDF, and found no statistical difference between the two (P=0.74). Inflammation and gingival staining were also evaluated in two of the three studies. No adverse effects were reported. All the included studies had a high risk of bias, and the certainty of the evidence was very low. Conclusion: SDF can be used as a safe and effective tooth desensitizer in adults, with good results, as was achieved in a short-term follow-up. However, more studies with longer evaluation periods are required.

Anxiety and Depression Symptoms During the COVID-19 Pandemic: A Cluster Analysis of Individuals Living in Portugal.

INTRODUCTION: The COVID-19 pandemic is an illustration of how a physical illness can damage people's minds. In this regard, the goal of this study was to see how different sociodemographic and behavioral factors were linked to anxiety and depression symptoms in a group of individuals living in Portugal. METHODS: Between November 2020 and February 2021, a cross-sectional, snowball online study was conducted. The study's target population was adults over the age of 18, residents of the country. For the statistical analysis, the clustering technique - K-means algorithm was applied. The chi-squared test was used to determine the relationships between clusters and sociodemographic and behavioral characteristics. Statistical analyses were conducted in R language, with a significance level of 0.05. A total of 453 participants were included. RESULTS: The majority were female (69.8%), under the age of 40 (60.8%), with a higher education degree (75.3%), and not married (54.4%). Furthermore, the majority were from the country's north region (66%). Cluster 1 (n = 194) was characterized by low or nonexistent levels of anxiety and depression symptoms, which means normal; cluster 2 by severe symptoms (n = 82), meaning case; and cluster 3 by mild symptoms (n = 177), which means borderline. Younger participants (p-value 0.024), female (p-value 0.041), with drinking habits (p-value 0.002), food insecurity (p-value < 0.001), food affordability exacerbation (p-value < 0.001), comorbidity (p-value < 0.001), use of anxiolytics (p-value < 0.001), insufficient household income (p-value 0.017) and income change (p-value < 0.001) were significantly associated with the anxiety-depression clusters. From the three clusters, cluster 2 was mainly represented by younger participants, with more persons stating that their household income was insufficient and that their income has changed as a result of COVID-19 and that they had the highest probability of food insecurity. CONCLUSION: The impacts of a crisis on mental health extend longer than the event itself. We were able to observe that younger women with insufficient household income who suffered a change in income due to COVID-19 and were classified as food insecure presented higher levels of anxiety and depression symptoms. These results highlight the presence of a social gradient where we saw that people who were less advantaged in terms of socioeconomic position presented worse mental health outcomes, stressing, in this sense, the need to bring the best public health responses for these specific groups of the population.

Proteomic Insights of Cowpea Response to Combined Biotic and Abiotic Stresses.

The co-occurrence of biotic and abiotic stresses in agricultural areas severely affects crop performance and productivity. Drought is one of the most adverse environmental stresses, and its association with root-knot nematodes further limits the development of several economically important crops, such as cowpea. Plant responses to combined stresses are complex and require novel adaptive mechanisms through the induction of specific biotic and abiotic signaling pathways. Therefore, the present work aimed to identify proteins involved in the resistance of cowpea to nematode and drought stresses individually and combined. We used the genotype CE 31, which is resistant to the root-knot nematode Meloidogyne spp. And tolerant to drought. Three biological replicates of roots and shoots were submitted to protein extraction, and the peptides were evaluated by LC-MS/MS. Shotgun proteomics revealed 2345 proteins, of which 1040 were differentially abundant. Proteins involved in essential biological processes, such as transcriptional regulation, cell signaling, oxidative processes, and photosynthesis, were identified. However, the main defense strategies in cowpea against cross-stress are focused on the regulation of hormonal signaling, the intense production of pathogenesis-related proteins, and the downregulation of photosynthetic activity. These are key processes that can culminate in the adaptation of cowpea challenged by multiple stresses. Furthermore, the candidate proteins identified in this study will strongly contribute to cowpea genetic improvement programs.

Does use of animal therapy during dental care help to reduce anxiety in children and adolescents? A systematic review.

BACKGROUND: Animal-assisted therapy (AAT) is considered a useful technique to reduce anxiety in children and adolescents in medical settings. AIM: To investigate whether the use of AAT helps to reduce anxiety during dental care in children and adolescents. DESIGN: Systematic review that included randomized and nonrandomized clinical trials with children up to 18-years of age undergoing dental appointments. The databases Embase, Cochrane, Pubmed/Medline, LILACS, PsycInfo, Scopus, and Web of Science were searched including gray literature. Random-effects meta-analyses using mean difference (MD) and narrative synthesis (vote counting) were implemented. Risk of bias was assessed using RoB2 for randomized clinical trials. The certainty of the evidence was performed using GRADE. RESULTS: A total of 1103 references were identified, and after a two-phase selection, three studies were included. Anxiety, behavior, and pain were the outcomes. A meta-analysis with 146 participants was performed for anxiety at three time points: before treatment (MD -0.40, CI: -1.06 to 0.26; I2  = 0%; p = .24), during treatment (MD -3.64, CI: -11.18 to 3.91; I2  = 94%; p = .34), and after treatment (MD -5.97, CI: -17.08 to 5.14; I2  = 98% p = .29). There was no difference during dental treatment with or without ATT (dogs), as well as for narrative analysis for any outcome. The risk of bias was high mainly because of the randomization and outcome measurement. CONCLUSION: There is no evidence to support or refute that the presence of AAT during dental care can help reduce anxiety in children (5-11 years). Studies with larger samples are suggested. Protocol registration (CRD42021293593).

Anthelmintic effect of a water soluble Moringa oleifera lectin in rodents experimentally infected with Haemonchus contortus.

Allied to the problem of gastrointestinal parasites, especially Haemochus contortus, the use of lectins of plant origin has contributed to the research of alternative anthelmintics. The nematicidal effect of a water soluble Moringa oleifera lectin (WSMoL) was investigated in an experimental model with H. contortus infected Wistar rodents. Three concentrations were tested orally: 5 mg/kg, 2.5 mg/kg and 1 mg/kg. The reduction in the number of larvae recovered in the experimental groups was analyzed, as well as biochemical, hematological and histological parameters. Treatments with 5, 2.5 and 1 mg/kg of WSMoL reduced the number of larvae recovered of animals by 74.7 %, 72.8 % and 66 %, respectively. Untreated infected animals had anemia, moderate mononuclear multifocal hepatitis, vascular congestion in the liver and kidneys, white pulp hyperplasia in the spleen, and presence of eosinophils in the intestine. Infected animals treated with 5 mg/kg of WSMoL showed liver with moderate bleeding, kidney with vascular congestion, spleen with white pulp hyperplasia and intestine with moderate presence of mononuclear cells. An increase in the serum level of glutamic pyruvic transaminase and a reduction in the level of hemoglobin (p < 0.001) were also observed in this group when compared to the uninfected group. However, the administered concentrations of 2.5 and 1 mg/kg of WSMoL were both satisfactory in terms of reducing the number of recovered larvae and not promoting negative changes in the biochemical, hematological and histological parameters evaluated. These results indicate an in vivo nematicidal effect of WSMoL on the H. contortus parasite.

HIV epidemic among Brazilian women who have sex with women: An ecological study.

The influences of public policies fighting HIV among women who have sex with women is scarcely studied. This study aimed to analyse the time series of human immunodeficiency virus (HIV) epidemic, between 2007 and 2020, among Brazilian women who have sex with women, in order to evaluate the effect of Brazilian policies for fighting HIV in this subpopulation compared to women who have sex with men (WSM). This ecological study employed HIV and acquired immunodeficiency syndrome (AIDS) new cases among women who have sex strictly with women (WSW), women who have sex with men and women (WSMW), and WSM reported to the Sistema de Informação de Agravos de Notificação from 2007 to 2020. Crude Brazilian and regional annual age-adjusted HIV/AIDS population-level incidence rates were calculated for WSW, WSMW and WSM. The rates were then analyzed using the Joinpoint regression model. A total of 102,890, 757, and 1,699 notifications of WSW, WSMW, and WSM living with HIV/AIDS were reported during the study period, respectively. South Brazilian region had the greatest HIV/AIDS incidence rates among WSM and bisexual women while the North region had the greatest incidence among WSW. In the WSM population, the temporal trends showed at least one stable or an increasing trend period from 2007 to 2013 or 2014, followed by one decreasing trend in all Brazilian regions. While among the WSMW most of the regions had a stable trend period from 2007 to 2020, in WSW group most of the trends had only one decreasing period. The decreasing trends were faster in WSM than in WSW. These results suggest a low efficiency of Brazilian policies for fighting HIV among WSW and WSMW and show the necessity of implementing new policies specific to this population.

Abortion and congenital transmission of Trypanosoma vivax in goats and ewes in semiarid northeastern Brazil.

The main effects of trypanosomosis in Brazil are related to reproductive alterations. In this context, the present study aimed to report the occurrence of abortions in goats and sheeps in the semiarid region of Northeastern Brazil, associated with Trypanosoma vivax. Trypomastigotes forms visualized by Buffy coat technique (BCT) method in 68.7% of the goats and 50.0% of the ewes that aborted. PCR identified that 100% of the goats and ewes that aborted were infected with T. vivax. The goats and ewes that aborted showed high parasitemia and developed clinical signs of trypanosomosis. The presence of T. vivax DNA was identified in the blood of fetuses by the PCR technique, proving infection by T. vivax in aborted fetuses, as well as confirming the congenital transmission of the parasite.

Professionals' beliefs in patient involvement for hospital safety.

OBJECTIVES: to analyze the beliefs of health care professionals about the benefits of patient involvement in care during hospitalization. METHODS: a descriptive, exploratory, qualitative study was conducted with 87 health professionals from a teaching hospital. Semi-structured interviews were conducted between December 2019 and January 2020 - data was submitted to content analysis and interpreted in light of Rosenstock's Model of Beliefs in Health. RESULTS: participants included nursing technicians, nurses, doctors, and other professionals. The categories "Professionals' beliefs about patient involvement in care", "Practices of patient involvement in care" and "Factors favoring patient involvement in hospital care" emerged. The perception of professionals revealed the influence of patient involvement in care outcomes and benefits for the safety of care. FINAL CONSIDERATIONS: involving the patient in care is associated with the healthcare professional's belief in the benefits of this practice for reducing incidents.

In vitro nematocidal activity of Punica granatum L. against gastrointestinal helminths in goats.

The objective of this study was to evaluate the in vitro ovicidal activity, phytochemistry, and toxicity of a saline extract obtained from peel of Punica granatum L fruits. The ovicidal activity was evaluated by the hatching inhibition of eggs recovered from fecal samples of naturally infected goats; the phytochemical analysis was carried out using the fruit peel; and the toxicity was tested on Artemia salina, using saline extract. The results showed that the ovicidal effect of the tested extract was 99% (25 mg mL-1), 99% (12.5 mg mL-1), 98% (6.25 mg mL-1), and 95% (3.12 mg mL-1), higher than that of the control drug, thiabendazole (83%). The phytochemical analysis showed presence of phenols, anthraquinones, and condensed and hydrolysable tannins in the fruit extract. The toxicity test of the extract of P. granatum showed an LC50 of 6.19 mg mL-1, which indicates a safe use for a concentration of 3.12 mg mL-1, since it was the tested concentration that was below the reliable LC50. The saline extract from peels of P. granatum has ovicidal activity, important secondary metabolites, and absence of toxicity at the lowest concentration tested. However, in vivo tests in experimental models are recommended before performing experiments in ruminants.

Existing predictive methods applied to gait analysis of patients with diabetes: study protocol for a systematic review.

INTRODUCTION: Type 2 diabetes can lead to gait abnormalities, including a longer stance phase, shorter steps and improper foot pressure distribution. Quantitative data from objective methods for evaluating gait patterns are accurate and cost-effective. In addition, it can also help predictive methods to forecast complications and develop early strategies to guide treatments. To date, no research has systematically summarised the predictive methods used to assess type 2 diabetic gait. Therefore, this protocol aims to identify which predictive methods have been employed to assess the diabetic gait. METHODS AND ANALYSIS: This protocol will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol (PRISMA-P) statement. Electronic searches of articles from inception to January 2022 will be performed, from May 2021 to 31 January 2022, in the Web of Science, MEDLINE, Embase, IEEE Xplore Digital Library, Scopus, CINAHL, Google Scholar, APA PsycInfo, the Cochrane Library and in references of key articles and grey literature without language restrictions. We will include studies that examined the development and/or validation of predictive methods to assess type 2 diabetic gait in adults aged >18 years without amputations, use of assistive devices, ulcers or neuropathic pain. Two independent reviewers will screen the included studies and extract the data using a customised charting form. A third reviewer will resolve any disagreements. A narrative synthesis will be performed for the included studies. Risk of bias and quality of evidence will be assessed using the Prediction Model Risk of Bias Assessment Tool and the Transparent Reporting of a multivariable prediction model for Individual Prognosis or Diagnosis. ETHICS AND DISSEMINATION: Ethical approval is not required because only available secondary published data will be analysed. The findings will be disseminated through peer-reviewed journals and/or presentations at relevant conferences and other media platforms. PROSPERO REGISTRATION NUMBER: CDR42020199495.

Nematicidal effect of a lectin preparation from Artocarpus heterophyllus (Moraceae) on larvae and adults of Haemonchus contortus.

Haemonchus contortus is a hematophagous parasite that causes damage to ruminant production worldwide. This study reported the in vitro nematicidal effect of a lectin preparation (LP) isolated from Artocarpus heterophyllus seeds on larvae and adults of H. contortus. The protein extraction was in phosphate-buffered saline followed by protein precipitation with ammonium sulfate 70% and dialysis. The dialyzed protein fraction was chromatographed to obtain isolated LP. The LP was characterized by hemagglutinating activity (HA) assays, protein dosage and polyacrylamide gel electrophoresis. The motility index of H. contortus in the third larval stage (unsheathed L3 larvae) and adult stage was evaluated. The HA inhibition of LP by mannose and galactose as well as the electrophoretic profile indicated the presence of the lectins ArtinM and Jacalin. The motility index of H. contortus was significantly reduced (p < 0.001) during the first 8 h of LP exposure, both in larvae (lowest index 8.3% with LP at 1 mg mL-1) and female adults (lowest index 20% with LP at 500 µg mL-1; index 40% with LP at 1 mg mL-1). This research revealed that the LP has potential for being utilized in the development of natural nematicides.

Reflectance confocal microscopy (RCM)-based criteria for progression of lower-lip squamous cell carcinoma: A prospective study.

BACKGROUND: Actinic cheilitis (AC) presents as a diffuse clinical-histopathological alteration throughout the lower lip. OBJECTIVES: To analyze AC lesions using reflectance confocal microscopy (RCM) and evaluate criteria for the early diagnosis of incipient squamous cell carcinoma (SCC). METHODS: This prospective study comprised cases of clinically diagnosed AC. RCM was performed over the entire extension of the lower lip. The sites that showed the highest degree of morphological alteration by RCM, according to established criteria for AC and SCC, were biopsied. The RCM findings and histopathology were correlated to establish the precise and early diagnosis of SCC. RESULTS: A total of 61 cases that had been clinically diagnosed with AC were included. The RCM findings that correlated independently with SCC were: nonedged papillae (sensitivity 84% and specificity 88%, p < 0.0001, and OR 42), cell-filled papillae (sensitivity 82% and specificity 93%, p < 0.0001, and OR 71.3), inflammation (sensitivity 68% and specificity 68%, p = 0.0163, and OR 4.8), large and roundish cells in the lamina propria (sensitivity 65% and specificity 100%, p < 0.0001, and OR infinity), and nests in the lamina propria (sensitivity 54% and specificity 100%, p < 0.0001, and OR infinity). An independent histopathological analysis classified the cases as partial epithelial dysplasia (25 cases, 41%) and SCC (36, 59%), and in 57 cases (94%), the results agreed with the categorization that was rendered by the RCM exam. CONCLUSIONS: RCM can be used to monitor AC cases, guide the biopsy site, and identify the early progression of AC to SCC with good sensitivity and specificity.
