- Abstract
BACKGROUND: In British Columbia (BC), Canada, clinicians are responsible for giving involuntary psychiatric patients rights information upon admission. Yet an investigation by the BC Office of the Ombudsperson found that clinicians are not always fulfilling this responsibility. The Ombudsperson recommended that the provincial government fund an independent body to give rights advice to patients. METHODS: To understand how clinicians feel about this recommendation, focus groups of clinicians who may give psychiatric patients rights information (n = 81) were conducted in Vancouver, BC, to probe their attitudes toward independent rights advisors. The focus group transcripts were thematically analyzed. RESULTS: Most clinicians believe that giving rights information is within their scope of practice, although some acknowledge that it poses a conflict of interest when the patient wishes to challenge the treatment team's decisions. Participants' chief concerns about an independent rights-advice service were that (a) patients may experience a delay in receiving their rights information, (b) integrating rights advisors into the workflow would complicate an already chaotic admission process, and (c) more patients would be counselled to challenge their hospitalization, leading to an increased administrative workload for clinical staff. However, many participants believed that independent rights advisors would be a positive addition to the admission process, both allowing clinicians to focus on treatment and serving as a source of rights-related information. CONCLUSIONS: Participants were generally amenable to an independent rights-advice service, suggesting that the introduction of rights advisors need not result in an adversarial relationship between treatment team and patient, as opponents of the proposal fear. Clearly distinguishing between basic rights information and in-depth rights advice could address several of the clinicians' concerns about the role that independent r

- Abstract
BACKGROUND: Median overall survival (OS) for women with high-grade serous ovarian cancer (HGSOC) is ∼4 years, yet survival varies widely between patients. There are no well-established, gene expression signatures associated with prognosis. The aim of this study was to develop a robust prognostic signature for OS in patients with HGSOC. PATIENTS AND METHODS: Expression of 513 genes, selected from a meta-analysis of 1455 tumours and other candidates, was measured using NanoString technology from formalin-fixed paraffin-embedded tumour tissue collected from 3769 women with HGSOC from multiple studies. Elastic net regularization for survival analysis was applied to develop a prognostic model for 5-year OS, trained on 2702 tumours from 15 studies and evaluated on an independent set of 1067 tumours from six studies. RESULTS: Expression levels of 276 genes were associated with OS (false discovery rate < 0.05) in covariate-adjusted single-gene analyses. The top five genes were TAP1, ZFHX4, CXCL9, FBN1 and PTGER3 (P < 0.001). The best performing prognostic signature included 101 genes enriched in pathways with treatment implications. Each gain of one standard deviation in the gene expression score conferred a greater than twofold increase in risk of death [hazard ratio (HR) 2.35, 95% confidence interval (CI) 2.02-2.71; P < 0.001]. Median survival [HR (95% CI)] by gene expression score quintile was 9.5 (8.3 to -), 5.4 (4.6-7.0), 3.8 (3.3-4.6), 3.2 (2.9-3.7) and 2.3 (2.1-2.6) years. CONCLUSION: The OTTA-SPOT (Ovarian Tumor Tissue Analysis consortium - Stratified Prognosis of Ovarian Tumours) gene expression signature may improve risk stratification in clinical trials by identifying patients who are least likely to achieve 5-year survival. The identified novel genes associated with the outcome may also yield opportunities for the development of targeted therapeutic approaches.

- Abstract
The World Health Organization has produced ethical guidance on implementation of the End TB strategy, which must be considered in local context. The Asia-Pacific Region has important distinctive characteristics relevant to tuberculosis, and engagement with the ethical implications raised is essential. This paper highlights key ethical considerations for the tuberculosis elimination agenda in the Asia-Pacific Regions and suggests that further programmatic work is required to ensure such challenges are addressed in clinical and public health programs.

- Abstract
Eugenol has pharmacological properties, but its impact on renal function is limitedly studied. Thus, this study evaluated the effects of eugenol at 10, 20, and 40 mg Kg
-1 , administered via gavage for 60 days, on histological, biochemical, oxidative, and proteomic parameters in rat kidneys. Adult Wistar rats treated with 10 mg Kg-1 of eugenol had kidneys with low total antioxidant capacity, high nitric oxide content, and high percentual of blood vessels, with no damage to renal function or morphology. The kidney proteome revealed an upregulation of proteins associated with energy metabolism, oxidative stress, and mitochondrial function. Eugenol at 20 mg Kg-1 did not alter kidney histology but inhibited Na+ /K+ ATPase activity. This dose elicited an upregulation of proteins associated with mitochondrial function and cellular defense. Finally, 40 mg Kg-1 eugenol had more pronounced effects on the kidney, increasing serum sodium, potassium, and chloride levels, inhibiting Na+ /K+ ATPase activity, triggering an adaptive response to oxidative stress and showed apical brush border thinness in proximal tubules. We concluded that eugenol exerted dose-dependent effects on kidney function and morphology. These findings highlight the importance of careful consideration of eugenol's dosage in therapeutic applications., 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 © 2025.

- Abstract
Question: How effective is an e-learning program based on international clinical guidelines in promoting beliefs more aligned with the current evidence for the management of low back pain among physiotherapists?, Design: Randomised controlled trial with concealed allocation and intention-to-treat analysis., Participants: 106 physiotherapists who treat patients with low back pain., Interventions: The experimental group received access to an e-learning program, based on recommendations of clinical practice guidelines for the management of low back pain, over a 6-week period. The program consisted of six units, totalling 15 hours, and was offered in a self-instructional and self-paced format. The control group was instructed to continue their activities as usual., Outcome Measures: The primary outcome was beliefs about low back pain measured using the Modified Back Beliefs Questionnaire (MBBQ, -50 worst to 50 best). Secondary outcomes included the Back Pain Attitudes Questionnaire (Back-PAQ, -20 worst to 20 best) and agreement with two statements (1: X-rays or scans are necessary to get the best medical care for low back pain; 2: Everyone with low back pain should have spine imaging). Participants were evaluated at baseline and 6 weeks., Results: Out of 53 participants allocated to the e-learning program, two completed only the first unit and one did not complete any units, resulting in an overall adherence rate of 94%. Compared with control, the e-learning program improved the MBBQ (MD 8 points, 95% CI 5 to 10) and the Back-PAQ score (MD 3.1 points, 95% CI 1.8 to 4.3). For the imaging beliefs statements, the e-learning program was able to increase the proportion of participants with beliefs aligned with the current evidence (statement 1: RD 38%, 95% CI 21 to 52; statement 2: RD 17%, 95% CI 7 to 29) compared with the control group., Conclusion: The e-learning program based on recommendations of clinical practice guidelines for the management of low back pain improved physiotherapists' beliefs about the management of low back pain., Registration: NCT05661968., (Copyright © 2024 Australian Physiotherapy Association.

- Abstract
The objective of this study was to evaluate the effect of dietary supplementation with Citrus sinensis (L.) Osbeck essential oil on the growth, immune system, and resistance to Aeromonas hydrophila infection in Colossoma macropomum fingerlings. The experiment was conducted with five treatments (control diet, Tween80 diet, and diets supplemented with 200, 400, and 800 mg L
-1 of C. sinensis essential oil) with four replicates. At the end of the experimental period, growth parameters were measured, and blood samples were collected for thrombogram, leukogram, and phagocytic activity analysis. A bacterial challenge with A. hydrophila was conducted for 96 h. C. macropomum fingerlings that were fed with 400 and 800 mg L-1 of C. sinensis essential oil had the highest growth parameters, with final weights of 533.18 ± 2.03 mg and 531.91 ± 2.67 mg, respectively, and an increase in the number of thrombocytes, lymphocytes, monocytes, and neutrophils, as well as higher phagocytosis rates compared to the control group. Regarding the challenge, fish in the 400 and 800 mg L-1 treatments also exhibited the lowest cumulative mortality rate (26.66% ± 3.33%). Therefore, supplementation with C. sinensis essential oil promotes growth, improves health, and enhances resistance to A. hydrophila in C. macropomum fingerlings., (© 2024 John Wiley & Sons Ltd.)- Published

- Abstract
This study aimed to explore the differences in the lipidome and mitochondrial fraction metabolome of Nellore cattle meat in different ranges of ultimate pH (pHu) normal (≤5.79), intermediate (5.80 to 6.19) and high (≥ 6.20) after 3- and 21-d postmortem. Instrumental color, myoglobin redox state, oxygen consumption, and metmyoglobin-reducing activity were measured during storage. A total of 472 lipids and 22 mitochondrial fraction metabolites were identified. Beef with high pHu showed positive regulation of ceramides involved in apoptosis and negative regulation of lipid classes related to membrane permeability and stability. In addition, lower carnitine content was noted in high-pHu beef than in normal-pHu beef. Acylcarnitines, phosphatidylinositol, and IMP showed upregulation in beef with intermediate pHu, indicating changes mainly related to energy, purine and pyruvate metabolism. Aging time impacted on the lipid content and metabolites involved in different metabolic pathways. These results provided new insights into beef's mitochondrial fraction lipid and metabolic profile with different pHu. In addition, beef with intermediate pHu differs from beef with high pHu due to changes in energy metabolism., 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
Tobacco use is the leading cause of death globally and in the U.S. After decades of decline, driven by decreases in combusted tobacco use, nicotine product use has increased due to Electronic Nicotine Delivery Systems (ENDS), also known as e-cigarettes or vapes. Preclinical models of nicotine self-administration can serve as important lodestars in the search for effective intervention and prevention tactics. Current variants of the task have substantial limitations, however. Therefore, we created the Rodent Electronic Nicotine Delivery System (RENDS), a novel low-cost non-proprietary snout-only preclinical model of self-administration of nicotine aerosol. We validated the RENDS using two techniques. First, we measured fine particulate matter (2.5 microns or less in diameter), generated by e-cigarettes, and showed that levels in the chamber were similar to room air when RENDS was in operation, confirming that nicotine aerosol is sequestered in the nose port. We also demonstrated that rats robustly self-administer flavored nicotine aerosol, resulting in high blood levels of cotinine (the major nicotine metabolite) and spontaneous somatic withdrawal symptoms. Thus, we provide strong validation of the operation and function of the RENDS, opening the door to an open-source preclinical aerosol model of nicotine self-administration that is far less costly. Four existing operant chambers can be retrofitted with the RENDS for under $1,300. All RENDS diagrams and plans for custom designed components can be found freely on our open science framework site (OSF; https://osf.io/x2pqf/?view_only=775b55435b8e428f98e6da384ef7889d).

- Abstract
Background/Objectives : Triple-negative breast cancer (TNBC) is the most challenging molecular subtype of breast cancer (BC) in clinical practice, associated with a worse prognosis due to limited treatment strategies and its insensitivity to conventional drugs. Zinc is an important trace element for homeostasis, and its Schiff base metal complexes have shown promise in treating advanced tumors. In this study, four new heteroleptic Zn(II) complexes ( 1 - 4 ) with Schiff bases were synthesized, characterized, and evaluated for their activity in BC cells. Methods : Compounds were synthesized, characterized, and their crystal structures were determined. Biological activity was assessed using MTT, clonogenic, scratch wound healing, caspase 3 and 8 activity, qPCR, and chemosensitization assays. Results : The complexes exhibited cytotoxicity against MCF-7 (luminal BC), MDA-MB-453 (HER2-positive BC), and MDA-MB-231 (TNBC) cell lines, with IC
50 values ranging from 0.01 to 20 µM. Complex 4 showed reduced cytotoxicity toward non-tumor cell lines. This, complexation with Zn(II) increased the cytotoxicity of the ligands, a trend not observed for complexes 1 - 3 . Due to its favorable profile, complex 4 was selected for further assays, in which it inhibited colony formation and the cell migration of TNBC cells in a dose-dependent manner. Furthermore, this compound induced cell death independently of caspases, decreasing the activity of caspase 8. Interestingly, complex 4 sensitized TBNC cells to doxorubicin and paclitaxel, possibly modulating the epithelial-mesenchymal transition mechanism, as evidenced by increased CDH1 expression. Conclusions : Results suggest the potential of complex 4 in sensitizing aggressive BC cells to chemotherapy, proving to be a promising alternative in cases of therapeutic failure.- Published

- Abstract
The association of bacteria resistant to potentially toxic metals (PTMs) with plants to remove, transfer, or stabilize these elements from the soil is an appropriate tool for phytoremediation processes in metal-contaminated environments. The objective of this study was to evaluate the potential of Rhizobium sp. LBMP-C04 for phytoremediation processes and plant growth promotion in metal-contaminated soils. Functional annotation allowed us to predict a variety of genes related to PTMs resistance and plant growth promotion in the bacterial genome. Resistance genes are mainly associated with DNA repair, and the import or export of metals in bacterial cells to maintain cell homeostasis. Genes that promote plant growth are related to mechanisms of osmotic stress tolerance, phosphate solubilization, nitrogen metabolism, biological nitrogen fixation, biofilm formation, heat shock responses, indole-3-acetic acid (IAA) biosynthesis, tryptophan, and organic acids metabolism. Biochemical tests indicated that Rhizobium sp. LBMP-C04 can solubilize calcium phosphate and produce siderophores and IAA in vitro in the presence of the PTMs Cd
2+ ,Cu2+ ,Cr3+ ,Cr6+ , Zn2+ , and Ni2+ . Results indicate the possibility of using Rhizobium sp. LBMP-C04 as a potentially efficient bacterium in phytoremediation processesin environments contaminated by PTMs and simultaneously promote plant growth., Competing Interests: Declarations.

- Abstract
Background: Human ascariasis is the most prevalent geohelminthiasis worldwide, affecting approximately 446 million individuals. In regions with endemic prevalence, the majority of infected adults are frequently exposed to the parasite and tend to have a low parasite load. Further studies are necessary to provide more evidence on the dynamics of infection and to elucidate the possible mechanisms involved in regulating protection, especially during the acute phase, also known as larval ascariasis. The aim of this study is to compare the impact of lung function between single and multiple infections in a murine model., Methods: We infected BALB/c mice considering the frequency of exposures: single-exposure-SI; twice-exposures-RE 2x and thrice-exposures-RE 3x, and considering the doses of infection: 25 eggs-RE 25; 250 eggs-RE 250 and 2,500 eggs-RE 2500, followed by infection challenge with 2,500 eggs. From this, we evaluated: parasite burden in lungs, cellular and humoral response, histopathological and physiological alterations in lungs., Results: The main results showed a reduction of parasite burden in the reinfected groups compared to the single-infected group, with protection increasing with higher exposure and dose. Furthermore, the RE 250 group exhibited a decrease of parasite burden close to RE 2500, but with less tissue damage, displaying the most favorable prognosis among the reinfected groups., Conclusion: Our research indicates a dose-dependent relationship between antibody production and the intensity of the immune response required to regulate the parasite burden., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Amorim et al.

- Abstract
We conducted a systematic review of randomized clinical trials evaluating the effects of aerobic, resistance and/or combined training on flow-mediated dilation (FMD) and/or pulse wave velocity (PWV) in older adults. The studies were selected from the electronic databases PubMed, Cochrane, LILACS, EMBASE, Web of Science, and the gray literature. We assessed the studies using Cochrane risk of bias (RoB2) tool and the GRADE tool. The GRADE assessment showed moderate quality of evidence for aerobic training and resistance training and very low for combined training. The measures of effects are presented as mean differences of the intervention group versus the control group and related 95% confidence intervals (95% CIs) pooled by a random-effects model using an inverse variance method. Our analysis of 24 RCTs (Intervention group [n = 251]: 67.7 ± 5.6 years old; control group [n = 228]: 68.7 ± 5.9 years old) showed that aerobic training was effective to improve FMD (0.64% [95% CI 0.24 to 1.03], p = 0.002) and PWV (-1.21 m/s [95% CI -1.37 to -1.05], p< 0.001) by compared to the control group. The subgroup analyses showed no FMD differences following aerobic training in healthy adults when compared to those with any health condition. Combined training was effective in improving FMD (0.60% [95% CI 0.50 to 0.71], p< 0.001) and PWV (-0.79 m/s [95% CI -1.23 to -0.35], p = 0.002). But these same parameters did not show any improvement in response to resistance training. A major limitation of this study is that the analysis to evaluate the effect of resistance training on PWV include only one study, and no inferences could be made from the data. Aerobic and combined training, but not resistant training, improve flow-mediated dilation and pulse wave velocity in the elderly.

- Abstract
Agroindustrial wastes are generated daily and seem to be rich in bioactive molecules. Thus, they can potentially be used as source of compounds able to control bacterial biofilms. We investigated the potential of extracts from the residues of rice and grape to combat clinically important bacterial biofilms. Extracts of grape pomace and rice bran were obtained using different extractive methodologies and subjected to the evaluation of its antimicrobial and antibiofilm activities. After the in vivo toxicity, the chemical characterization of the most promising extract was assessed. The mass spectrometry analysis revealed the presence of dipeptides, alkaloids and phenolic compounds. Most grape extracts presented antibiofilm and antimicrobial activities against Staphylococcus epidermidis ATCC 35984 and Pseudomonas aeruginosa PA14. The hydromethanolic grape pomace extract obtained by ultrasound assisted extraction (MeOH 80 UAE) presented the most promising activity, being able to inhibit in 99 % and 80 % the biofilm formation of S. epidermidis and P. aeruginosa, respectively. Against the gram-negative model, this extract eradicated the biofilm by 80 %, induced the swarming motility and displayed a physical effect. It also did not present acute or chronic toxicity in Caenorhabditis elegans model. In this way, agroindustrial residues represent a promising source of molecules capable of controlling bacterial biofilms., Competing Interests: Declaration of Competing interest No conflict of interest is declared by the authors., (Copyright © 2024 Elsevier Ltd.

- Abstract
The study aimed to evaluate the in vitro anthelminthic and antimicrobial activity of silver nanoparticles (AgNPs) against Dactylogyrus minutus and Aeromonas hydrophila, pathogens of Cyprinus carpio Koi. Gill arches of the fish were removed and placed into six-well plates containing 10 mL of tank water with varying concentrations of AgNPs: 100, 400, 500, 600, and 800 mg/L, along with control groups using tank water and distilled water. Each group was tested in triplicate. Parasites were observed every 10 min for 300 min (5 h) using a stereomicroscope, and mortality rates were recorded. Anthelminthic efficacy was calculated at the end of the tests. For the in vitro antimicrobial test, the Minimum Inhibitory Concentration (MIC) of AgNPs was determined by adding 100 μL of Poor Broth (PB) culture medium to all 96 wells of a microplate. The first well was filled with 100 μL of AgNPs, followed by serial dilutions (1:2 ratio). Subsequently, 50 μL of A. hydrophila (1 × 10
7 CFU/mL) was added to all wells and incubated for 24 h at 28 °C. Results showed that 800 mg/L of AgNPs achieved 87% anthelminthic efficacy within 300 min, while 100 mg/L achieved 47% efficacy. The MIC showed bacterial growth inhibition at 125 mg/mL. Despite the 87% efficacy against parasites within 300 min, AgNPs did not reach 100% efficacy quickly, limiting their potential use in ornamental fish farming. Further studies are needed to assess the toxicity of AgNPs in fish., 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 Inc.

- Abstract
Background: Lymphangioleiomyomatosis (LAM) is a rare (twenty-one per million female inhabitants) neoplastic cystic lung disease that impairs health-related quality of life (HRQoL). However, the factors associated with impaired quality of life in patients with LAM are poorly understood., Objective: To assess the clinical, psychosocial, and functional characteristics associated with impaired quality of life in patients with LAM., Methods: This was a cross-sectional study performed on two nonconsecutive days. HRQoL (SF-36 and CRQ), lung function tests, anxiety and depression symptoms (HADS), maximal (CPET and ISWT), and submaximal exercise capacity (6MWT) were assessed. Linear associations among outcomes were assessed using Pearson's correlation and multivariate tests., Results: Forty-five women with LAM (46 ± 10.years; FEV
1, 74%pred) were evaluated. The lowest SF-36 scores were observed for general health and vitality and the highest for the physical and social domains. The lowest CRQ scores were observed for dyspnea and fatigue, and the highest were for the emotional function and self-control domains. Sixteen (35%) women had anxiety, and 8 (17%) had depression symptoms. Most of the SF-36 and CRQ domains were associated with anxiety and depression symptoms (from r = 0.4 to r = 0.7; p < 0.05) and exercise capacity (from r = 0.3 to r = 0.5; p < 0.05). Lung function parameters were weakly or not associated with quality of life domains. After multiple linear regression, HRQoL was independently associated with depression symptoms and physical capacity but not with lung function., Conclusion: Our results show that aerobic capacity and depression symptoms are the main factors, rather than lung function, related to quality of life in patients with LAM., (© 2024.

- Abstract
Whether ibrutinib-related atrial fibrillation (IRAF) is a dose-dependent adverse drug reaction (ADR) and whether ibrutinib should be discontinued or dose-reduced in case of IRAF occurrence remains unknown. Using the World Health Organization individual case safety report pharmacovigilance database, VigiBase®, we aimed to determine the association between ibrutinib dosing regimens and IRAF reporting. Ibrutinib daily dose was extracted from IRAF cases from VigiBase® and was divided into 5 ibrutinib dosing regimen (140-280-420-560 and >560 mg/day). Disproportionality analysis was used to evaluate the association between IRAF reporting and ibrutinib daily dose, through logistic regression. Single term deletions produced the ibrutinib daily dose global p-value. Then, a multivariable adjusted reporting odds-ratio with its 95% confidence interval was calculated for each ibrutinib dosing regimen, against the lowest dosing regimen (140 mg/day) as reference. A total of 1162 IRAF cases were identified in VigiBase® (n = 62 for ibrutinib 140 mg/day, 114 for ibrutinib 280 mg/day, 811 for ibrutinib 420 mg/day, 164 for ibrutinib 560 mg/day and 11 for ibrutinib >560 mg/day). After adjustment on several variables of interest, IRAF reporting was not significantly associated with ibrutinib dosing regimen (p = 0.09). Our results from Vigibase® do not support IRAF as a dose-dependent ADR (ClinicalTrial registration number: NCT06224452)., Competing Interests: Competing interests: JA reports honoraria for presentations and consulting fees from Biotronik, Bioserenity, Amgen, BMS, Pfizer, Boerhinger, Bayer, Astra Zeneca, Janssen, Servier, and Novartis, outside of the submitted work.

- Abstract
Background: The role of nitric oxide (NO) in plant stress tolerance, as well as in increasing post-harvest quality, has been extensively demonstrated in several fruits and vegetable crops; however, the effects of its pre-harvest application on post-harvest quality are still poorly documented. Therefore, the pre-harvest application of NO in red beet (Beta vulgaris subsp. vulgaris) plants cultivated under well-watered and drought conditions was evaluated to assess whether it improves the post-harvest quality of their storage roots. Red beet plants cultivated under well-watered (80% of water holding capacity) or drought condition (15% of water holding capacity) were sprayed weekly with water (control) or 100 μmol L
-1 sodium nitroprusside (SNP), an NO donor. Sixty-six days after sowing, red beet roots were harvested, and root yield, total sugar yield, reducing sugars, non-reducing sugars, proteins, lipids, root ashes, root moisture, soluble solids, titratable acidity, pH, vitamin C, total phenolics, total betalains, betacyanins, betaxanthins and antioxidant capacity were determined., Results: While drought led to a reduction in root yield, sugars, lipids and titratable acidity, it increased phenolic compounds, betalains and the antioxidant capacity of beets. SNP reversed the negative effects of drought on sugar, lipid and organic acid contents and increased antioxidant capacity independent of stress., Conclusion: Pre-harvest SNP treatment reversed drought-induced yield reductions in beets, while boosting bioactive compounds and antioxidant capacity. It also enhanced vitamin C content independently, indicating its dual role in stress mitigation and beet quality improvement. Future research should explore other crops and stress conditions. © 2024 Society of Chemical Industry., (© 2024 Society of Chemical Industry.)- Published

- Abstract
Background: Clinical staging (CS) and tumor burden (TB) play a significant role in FL prognosis and direct its up-front therapy. The aim of this study is to report prognostic factors and clinical outcomes in newly-diagnosed FL patients stratified according to CS and TB in early-stage (ES) disease, advanced-stage with low tumor burden (AS-LTB) and advanced-stage with high tumor burden (AS-HTB). Methods: Two hundred fourteen patients with FL grades 1-3A had baseline clinical characteristics and outcomes assessed. Survival according to up-front immunochemotherapeutic (ICT) regimens was assessed in the AS-HTB subgroup. Independent predictors for OS, PFS, POD-24, and Histological Transformation (HT) were identified. Results: Seventy-five percent of cases were categorized as AS-HTB, 13.5% as AS-LTB and 11.5% as ES. With a median follow-up of 8.15 years, the estimated 5-year OS and PFS were 75.4% and 57.2%, respectively. OS, but not PFS was markedly decreased in AS-HTB FL patients compared to ES and AS-LTB cases. POD-24 rate was 21.7% and overall mortality rate was 38.7% during the entire follow-up. The annual cumulative rate of HT to high-grade B-cell lymphoma (HGBCL) was 0.5%, and higher in AS-HTB cases, in comparison to ES and AS-LTB. Considering patients with AS-HTB there were no differences in clinical outcomes among cases submitted to ICT based on R-CHOP, R-CVP and regimens containing purine analogs. Additionally, ECOG ≥ 2, hypoalbuminemia, B-symptoms and HT were independently associated with poor survival. High content of centro-blasts (grade 3A), involvement of ≥3 nodal sites by FL and rituximab omission in up-front therapy predicted POD-24. Conclusions : FL has marked clinical-prognostic heterogeneity, translated into diverse CS and TB subcategories. Here, we demonstrated that FL patients classified as AS-HTB demonstrated decreased survival and higher rates of HT to HGBCL compared to ES and AS-LTB cases. Prognostic factors identified in our analysis may help to identify FL patients with higher-risk of HT and early-progression (POD-24).

- Abstract
Background: The COVID-19 pandemic has had an impact on the eating habits of the general population, among other reasons, because it has affected access to commercial establishments since some of them closed. This study aimed to describe potential changes that occurred between 2019 and 2022 in the availability and affordability of food and beverages in the food environment of a Brazilian public university., Methods: Cross-sectional and descriptive study conducted at a public university located in Rio de Janeiro, Brazil. Audits were carried out in all establishments selling food and beverages at the university's main campus in 2019 and 2022. Descriptive analysis with frequencies and means was carried out and the 95% confidence intervals were compared., Results: Over the period, there was a decrease in the on-campus number of establishments, dropping from 20 to 14, and ultra-processed foods became more prevalent. In general, the decrease in the number of establishments led to a reduction in the supply of fresh or minimally processed foods and beverages, and higher average prices were noted., Conclusions: The pandemic seems to have deteriorated the availability and the prices of healthy food in the university food environment, making healthy choices harder for students and the university community.

- Abstract
Introduction: In Brazil, the emergence of feline sporotrichosis, a neglected subcutaneous mycosis primarily transmitted by cats and caused by the fungus Sporothrix brasiliensis, has been monitored via molecular tools. This approach underscores the geographic expansion of this disease and highlights the critical role of molecular surveillance in understanding its epidemiology and guiding public health interventions., Methods: We investigated three domestic cats (Felis catus) with multiple skin lesions in Picos, Piauí, Brazil. The cats were examined, and samples were collected for laboratory diagnosis, including cytological evaluation, fungal culture, and molecular characterisation. The molecular analysis involved a one-tube multiplex probe-based qPCR assay for the diagnosis of Sporothrix species, mating-type determination, and amplified fragment length polymorphism (AFLP, EcoRI-GA/MseI-AG) to assess genetic similarity and potential origin., Results: All three cats were diagnosed with sporotrichosis caused by the hypervirulent S. brasiliensis. A probable case of zoonotic transmission has been reported in a 12-year-old girl who developed Parinaud oculoglandular syndrome after contact with one of the cats with sporotrichosis. The molecular analysis revealed that the cat isolates were MAT 1-2 and formed a single cluster according to the AFLP analysis, suggesting direct transmission (cat-cat) and a potential founder effect. The isolates were also closely related to strains from Pernambuco and Southeast Brazil, indicating a possible introduction from these regions., Conclusions: Identifying S. brasiliensis in Piauí emphasises the need for increased awareness and control measures to prevent further spread. The predominance of the MAT1-2 idiomorphs and the genetic similarity among outbreak isolates suggest clonal expansion, which could have significant implications for public health and veterinary practices. Considering its zoonotic potential and environmental adaptability, a One Health approach is crucial for managing and controlling the spread of cat-transmitted sporotrichosis., (© 2024 Wiley‐VCH GmbH.)

- Abstract
Background/objective: Eating behaviors (EB) correlate with weight loss after bariatric surgery (BS). Therefore, the investigation of EB could guide interventions to prevent insufficient weight outcomes., Method: A prospective cohort of 85 patients undergoing Roux-en-Y Gastric Bypass (RYGB; 84.7% female, mean age 44.7 ± 9.3 years) was included. Six months after undergoing RYGB, EB patterns, including cognitive restraint (CR), uncontrolled (UE), and emotional eating (EE), were assessed using the Three-Factor Eating Questionnaire R21 (TFEQ-R21). History, physical examination, and anthropometric assessments were collected pre- and 12 months postoperative. Patients were divided based on the percentage of excess weight loss (%EWL < 80% or ≥80%) and EB patterns were correlated with weight outcomes at 12 months., Results: The %EWL ≥ 80% group demonstrated significantly higher scores in CR and EE compared to %EWL < 80% ( p < 0.001 and p = 0.01, respectively). UE scores were similar between groups ( p = 0.41). At 12 months postoperative, the %EWL ≥ 80% group had negative correlations between CR and BMI and positive correlations between CR and EWL (rho = -0.33 and rho = 0.29; p = 0.04). Multiple logistic regression considering %EWL ≥ 80% as the aim outcome revealed that CR had a significant influence (OR = 1.037; p = 0.058), while age (OR = 0.962; p = 0.145), sex (OR = 2.984; p = 0.135), UE (OR = 0.995; p = 0.736), and EE (OR = 1.017; p = 0.296) did not., Conclusions: EBs influence outcomes after BS, and a model using TFEQ-R21 predicted them. CR six months post-surgery was the strongest predictor of higher EWL at 12 months. Further research is needed to understand the relationship between restrictive EB and BS outcomes, possibly identifying strategies to prevent disordered EB in patients with higher scores.

- Abstract
Inorganic nanoparticles are nanomaterials with a central core composed of inorganic specimens, especially metals, which give them interesting applications but can impact the environment and human health. Their short- and long-term effects are not completely known and to investigate that, alternative models have been successfully used. Among these, the nematode Caenorhabditis elegans has been increasingly applied in nanotoxicology in recent years because of its many features and advantages for toxicological screening. This non-parasitic nematode may inhabit any environment where organic matter is available; therefore, it is interesting for ecotoxicological assessments. Moreover, this worm has a high genetic homology to humans, making the findings translatable. A notable number of published studies unraveled the level of toxicity of different nanoparticles, including the mechanisms by which their toxicity occurs. This narrative review collects and describes the most relevant toxicological data for inorganic nanoparticles obtained using C. elegans and also supports its application in safety assessments for regulatory purposes., (© 2024 John Wiley & Sons Ltd.)

- Abstract
This review delves into the pivotal primordial stage of the universe, a period that holds the key to understanding its current state. To fully grasp this epoch, it is essential to consider three fundamental domains of physics: gravity, particle physics, and thermodynamics. The thermal history of the universe recreates the extreme high-energy conditions that are critical for exploring the unification of the fundamental forces, making it a natural laboratory for high-energy physics. This thermal history also offers valuable insights into how the laws of thermodynamics have governed the evolution of the universe's constituents, shaping them into the forms we observe today. Focusing on the Standard Cosmological Model (SCM) and the Standard Model of Particles (SM), this paper provides an in-depth analysis of thermodynamics in the primordial universe. The structure of the study includes an introduction to the SCM and its strong ties to thermodynamic principles. It then explores equilibrium thermodynamics in the context of the expanding universe, followed by a detailed analysis of out-of-equilibrium phenomena that were pivotal in shaping key events during the early stages of the universe's evolution.

- Abstract
Salicylic acid (SA) is a bioregulator well-known for mitigating salinity damage in plants. However, no studies have examined the interaction between SA and salinity in Dizygostemon riparius , a species rich in bioactive molecules. Therefore, we aimed to evaluate the effect of SA application on Dizygostemon riparius under different salinity levels. A completely randomized experiment was conducted in a 2 × 3 factorial design (two SA concentrations of 0 and 100 µM and three salinity concentrations of 0, 200, and 400 mM NaCl) with five replicates. At 400 mM NaCl, leaf temperature increased by 11%, while relative water content and total soluble carbohydrates decreased by 30% and 35%, respectively, leading to reduced biomass accumulation. Notably, the SA application mitigated these effects by restoring relative water content under 400 mM NaCl and improving carboxylation efficiency and intrinsic water-use efficiency under 200 mM NaCl. Additionally, dry biomass was maintained under both 200 and 400 mM NaCl with SA treatment. These findings suggest that SA has a promising potential to alleviate salt stress in Dizygostemon riparius . Our results could inform cultivation practices, opening new perspectives on the use of SA as an attenuator of salinity stress.

- Abstract
Overexposure to blue light due to the excessive use of electronic devices has been implicated in premature skin aging and eye damage, among other injuries to health. This study aimed to synthesize two azo derivatives of the 2-(amino-2'-hydroxyphenyl) benzoxazole and explore their potential as UV and blue light filters, proposing a new spectral profile. The synthesis of the heterocyclic compounds involved condensation reactions and diazotation. The derivatives 2-(benzoxazol-2-yl)-5-[(2-hydroxynaphthyl)diazenyl]phenol and 2-(benzoxazol-2-yl)-4-[(2-hydroxynaphthyl)diazenyl]phenol were synthesized with a yield greater than 70%. Solubility was evaluated in seven different solvents. The maximum absorption wavelengths (λ
max ) were determined using UV-Vis scanning spectrophotometry in the range of 200-600 nm. Photostability was assessed using a solar simulator and the Sun protection factor (SPF) was determined using in vitro methodology. Cytotoxicity was evaluated using the MTT assay in V79 cells. These compounds were able to absorb UVA, UVB, and blue light, with λmax ranging from 300 to 500 nm and demonstrated photostability after 3 h of exposure to solar simulator with an SPF higher than 45. The compounds exhibited solubility in all lipophilic solvents tested. Regarding cytotoxicity, IC50 values were comparable to other filters. These findings indicate that both compounds hold promise as potential organic filters., (© 2024 John Wiley & Sons Ltd.)- Published

- Abstract
We examined the zoographics, or the characteristics of nonhuman animal subjects, reported for the entirety of the Journal of the Experimental Analysis of Behavior (JEAB) through the most recent complete year (1958-2023). Animal sex in particular was evaluated to determine whether the lack of inclusion of female subjects in other disciplines extends to JEAB. Through systematic coding of all nonhuman empirical articles, we found consistent underreporting of most zoographics and a disproportionate use of male subjects relative to female subjects. Additionally, animal sex was commonly unreported and the inclusion of both male and female subjects was sparse. Recent years show some improvement, but greater inclusion is required. Lack of female subjects in research as well as underreporting of zoographics can generate unrepresentative results and hamper replication, generalization, and translation. We provide resources to guide future research and reporting suggestions such as equal inclusion and disaggregation of data by sex. We also clarify misunderstandings about the use of both sexes in research such as beliefs that it necessarily increases the cost of research., (© 2024 Society for the Experimental Analysis of Behavior.)

- Abstract
Reducing systemic inequities in testing, access to care, social protection - and in the scientific process - is essential to end TB. Incorporating social science methods and expertise on inequity into the mainstream TB response would help ensure that political commitments to equity move beyond symbolic gestures. We convened a meeting between TB social scientists, people with lived experience, civil society and community members to discuss equity within the global TB response. Here, we propose five means by which a social science lens can strengthen equitable, person-centred responses and reconcile the public health significance of TB with the principles of social justice.

- Abstract
Acanthocephalan parasites, specifically from the genus Profilicollis, are known to infect decapod crustaceans, including mole crabs like Emerita brasiliensis, which serve as intermediate hosts in their complex life cycles. This study reports the first occurrence of the acanthocephalan parasite Profilicollis altmani infecting the mole crab Emerita brasiliensis on a sandy beach in southeastern Brazil, thereby expanding the known geographic range of this parasite. Additionally, the study provides novel molecular data that enhance our understanding of the parasite's taxonomy and distribution, including the first evidence of genetic variation within populations of the intermediate host E. brasiliensis. Phylogenetic analysis based on mitochondrial COX1 gene sequences confirmed the identification of the parasite and underlined small genetic differences among P. altmani populations. These findings suggest a weak genetic population structure of the parasite and underscore the need for further studies to understand gene flow among these populations. This work contributes to the knowledge of parasite-host interactions in sandy beach ecosystems. It highlights the importance of monitoring parasitic infections in species like E. brasiliensis, which play a crucial ecological role in these environments., 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 Inc.

- Abstract
Objective: To describe pulmonary function, muscle strength and functional performance in the different qualities of sleep and the impact of this on the number of physiotherapeutic assistances., Methods: This is an observational study. In the pre and post operative period, sleep behavior was evaluated using the Pittsburgh questionnaire. Patients were divided into three groups: Good Sleep Quality (GSQ), Poor Sleep Quality (PSQ) and Sleep Disordered (SDB). At this time, other tests were also performed, such as: 6-Minute Walk Test (6MWT), Sit and Stand Test (SST), gait speed test and Timed Up to Go (TUG), Medical Research Council (MRC), maximal inspiratory pressure and maximal expiratory, vital capacity and peak expiratory flow. The functional performance and lung function of each group were compared., Results: A total of 105 people, undergoing cardiac surgery and admitted to hospital were evaluated, 33 with GSQ, 41 with PSQ and 31 with SD. Patients who were in the SDB group had a lower functional performance than the other groups. 6MWT (meters) in the GSQ was 499 ± 87, versus 487 ± 91 in the PSQ and 430 ± 78 in the SD (p = 0.02). In the SST (seconds) it was 10.4 ± 1.1 in the GQS, 11.1 ± 2.3 in the PSQ and 15.4 ± 2.1 in the SD (p = 0.04). Lung function and muscle strength did not differ between groups. Regarding the refusal to perform physical therapy, the SD group was more incident, the main reason being drowsiness., Conclusion: Based on the results, we found that sleep quality interferes with functional performance and physical therapy assistance during the hospital stay in patients undergoing cardiac surgery., (Copyright © 2024.

- Abstract
This study aimed to perform in vitro antiparasitic and antimicrobial tests with the essential oil (EO) of Schinus terebinthifolius against of fish and shrimp. The chemical composition of the EO of S. terebinthifolius was determined by gas chromatography. For the antiparasitic test, the protozoan Epistylis sp. obtained from parasitized Oreochromis niloticus was used, and exposed to different concentrations of EO (2%, 1%, 0.5%, 0.25%), and control with 1% grain alcohol. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) test with EO of S. terebinthifolius evaluated the antimicrobial potential, with serial dilutions starting at 2% and control with 1% grain alcohol, using the strains of Aeromonas hydrophila (2.2 × 10
8 CFU mL-1 ), Edwardsiella tarda, Vibrio parahaemolyticus, V. harveyi, and V. alginolyticus (2.0 × 108 CFU mL-1 ). Chemical analysis revealed that the major EO compounds of S. terebinthifolius were δ-3-Carene (56.00%) and α-Pinene (16.89%). In the antiparasitic test, the concentration of 2% EO showed 100% efficacy against Epistylis sp. within 5 min. In the antimicrobial tests, the concentration of 2% EO was effective against all bacteria tested. The EO of S. terebinthifolius demonstrated antiparasitic and antimicrobial activity at a concentration of 2%, standing out as an alternative to conventional antibiotics., (© 2024 John Wiley & Sons Ltd.)- Published

- Abstract
This study investigated the in vitro antimicrobial and anthelmintic effect of copper nanoparticles (CuNPs) against the bacterium Aeromonas hydrophila, the monogeneans Dactylogyrus minutus, Dactylogyrus extensus, Gyrodactylus cyprini, and the cestode Schyzocotyle acheilognathi, as well as their toxicity to Cyprinus carpio Koi. In the antimicrobial in vitro test, the inhibition zone method and minimum inhibitory concentration (MIC) were performed. In order to determine the time and efficacy of monogenean parasite mortality, the parasites were exposed to CuNP concentrations of 20, 50, 100, 150, 200, and 300 mg L
-1 , and a control group with tank water and one with copper sulphate pentahydrate (CuSO4 .5 H2 O) at a concentration of 0.3 mg L-1 , performed in triplicate. The parasites were observed every 10 min for 300 min, and mortality was recorded. For the cestodes, parasites were immersed in CuNP concentrations of 50, 100, 150, and 300 mg L-1 . At the end of the in vitro tests, the anthelmintic efficacy of each treatment was calculated. To assess the tolerance and toxicity in fish, they were exposed to CuNP concentrations of 0.6, 1.25, 2.5, 5, 10, 20, and 50 mg L-1 for 12 h. The MIC demonstrated that CuNPs effectively inhibited the growth of A. hydrophila up to a dilution of 12,500 mg L-1 and showed an inhibition zone of 14.0 ± 1.6 mm for CuNPs. The results of anthelmintic activity showed a dose-dependent effect of concentration for both groups of parasites, with the most effective concentration being 300 mg L-1 in 120 min. In the toxicity test, the carps showed tolerance to lower concentrations. The study indicated that CuNPs were effective against the studied pathogens. However, it proved to be toxic to fish at high concentrations. The use of low concentrations is recommended still requires further investigation., (© 2024 John Wiley & Sons Ltd.)- Published

- Abstract
Introduction. Efforts to understand the burden of antibiotic use in low- and middle-income countries such as Brazil are essential for developing strategies that are effective and appropriate in the context of endemic multidrug-resistant organisms. Aim. This study aims to determine antimicrobial-prescribing practices among patients hospitalized in intensive care units (ICUs) for adults in Brazil. Methodology. A 1-day point prevalence multicentre survey was conducted in 58 adult ICUs across the five regions of Brazil. The institutions were categorized according to their type and size. Detailed antimicrobial prescription data were prospectively provided to all patients hospitalized on the day of data collection. Results. A total of 620 patients were included in the study, of whom 63.9% were receiving at least one antimicrobial. Of these, 34.6% were treated for an infection, but only 39.9% of the cases were based on microbiological criteria. Empirical treatment was applied to 72.3% of the patients. Significant differences in antibiotic usage were observed across the different hospitals included in the study. Overall, treatment was most commonly directed towards pneumonia (51.8%) and bloodstream infections (29.6%). Glycopeptides (19.4%) and carbapenems (18.5%) were the most prescribed in teaching hospitals, while in non-teaching hospitals, carbapenems (17.8%) and broad-spectrum cephalosporins (16.8%) were most frequently used. Conclusion. Our study reveals alarming data on antibiotic use in adult ICUs in Brazil, with high frequencies of severe healthcare-associated infections acquired in these units, where patients are frequently subjected to empirical treatment.

- Abstract
The snack food market has been changing to keep up with the growing demand for healthier products and, as a result, alternative products to traditional potato chips have been emerging to provide health-related benefits. Extrusion, frying, and baking are the main techniques used worldwide in the processing of snacks and are among the main reasons for the formation of toxic compounds induced by heat, such as acrylamide. This contaminant is formed during thermal processing in foods heated at high temperatures and rich in carbohydrates. Processed potato-based products have been pointed out as the main contributors to acrylamide dietary exposure. Many studies have been conducted on potato chips since the discovery of this contaminant in foods and research on the formation of acrylamide in snacks from other vegetables has begun to be conducted more recently. Thus, this review aims to present a detailed discussion on the occurrence of acrylamide in alternative vegetable snacks that are consumed as being healthier and to address relevant questions about the effectiveness of mitigation strategies that have been developed for these products. Through this research, it was observed that, depending on the vegetable, the levels of this contaminant can be quite variable. Alternative snacks, such as sweet potato, carrot and beetroot may also contain high levels of acrylamide and need to be monitored even more closely than potatoes snacks, as less information is available on these food products. Furthermore, various pretreatments (e.g. bleaching, immersion in solutions containing chemical substances) and processing conditions (heating methods, time, temperature) can reduce the formation of acrylamide (54-99 %) in alternative vegetable snacks., 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
Aims: Trigeminal neuralgia (TN) is a type of chronic orofacial pain evoked by trivial stimuli that manifests as episodes of excruciating and sudden, recurrent paroxysmal pain. Most patients are refractory to pharmacological therapy used for the treatment of TN. Mononuclear cells (MNC) and mesenchymal stem/stromal cells (MSC) have shown therapeutic potential in painful neuropathies, but their mechanism of action is not fully understood. The present work aimed to investigate the antinociceptive effect and mechanism of action of MNC and MSC in experimental TN., Materials and Methods: Mice submitted to the chronic constriction injury of the infraorbital nerve (CCI-ION) mouse model of TN received a single intravenous injection of saline, MNC, or MSC (1 × 10
6 cells/mouse). The effect of the treatments on the behavioral signs of painful neuropathy, morphological aspects of the infraorbital nerve, and inflammatory and oxidative stress markers in the infraorbital nerve were assessed., Key Findings: MNC and MSC improved behavioral painful neuropathy, activated key cell signaling antioxidant pathways by increasing Nrf2 expression, and reduced the proinflammatory cytokines IL-1β and TNF-α. However, treatment with MSC, but not MNC, was associated with a sustained increase of IL-10 and with the re-establishment of the morphometric pattern of the infraorbital nerve, indicating a difference in the mechanism of action between MNC and MSC. In line with this result, in IL-10 knockout mice, MSC transplantation did not induce an antinociceptive effect., Significance: Importantly, these data suggest an IL-10-induced disease-modifying profile related to MSC treatment and reinforce cell therapy's potential in treating trigeminal neuralgia., Competing Interests: Declaration of competing interest The authors declare that there are no conflicts of interest., (Copyright © 2024 Elsevier Inc.

- Abstract
Zika virus (ZIKV) infection during pregnancy can lead to a set of congenital malformations known as Congenital ZIKV syndrome (CZS), whose main feature is microcephaly. The geographic distribution of CZS in Brazil during the 2015-2017 outbreak was asymmetrical, with a higher prevalence in the Northeast and Central-West regions of the country, despite the ubiquitous distribution of the vector Aedes aegypti, indicating that environmental factors could influence ZIKV vertical transmission and/or severity. Here we investigate the involvement of the most used agrochemicals in Brazil with CZS. First, we exposed human neuroblastoma SK-N-AS cells to the 15 frequently used agrochemical molecules or derivative metabolites able to cross the blood-brain barrier. We found that a derived metabolite from a widely used herbicide in the Central-West region, 2,4-dichlorophenoxyacetic acid (2,4D), exacerbates ZIKV neurotoxic effects in vitro. We validate this observation by demonstrating vertical transmission leading to microcephaly in the offspring of immunocompetent C57BL/6J mice exposed to water contaminated with 0.025 mg/L of 2,4D. Newborn mice whose dams were exposed to 2,4D and infected with ZIKV presented a smaller brain area and cortical plate size compared to the control. Also, embryos from animals facing the co-insult of ZIKV and 2,4D exposition presented higher Caspase 3 positive cells in the cortex, fewer CTIP2+ neurons and proliferative cells at the ventricular zone, and a higher viral load. This phenotype is followed by placental alterations, such as vessel congestion, and apoptosis in the labyrinth and decidua. We also observed a mild spatial correlation between CZS prevalence and 2,4D use in Brazil's North and Central-West regions, with R
2 = 0.4 and 0.46, respectively. Our results suggest that 2,4D exposition facilitates maternal vertical transmission of ZIKV, exacerbating CZS, possibly contributing to the high prevalence of this syndrome in Brazil's Central-West region compared to other regions., (© 2024 Wiley Periodicals LLC.)- Published

- Abstract
Purpose: To evaluate the effect of 890 nm Monochromatic Infrared Light (MIR) associated with a physical therapy protocol on pain in individuals with diabetic Distal Symmetric Polyneuropathy., Methods: Randomized, parallel, double-blind controlled trial conducted with individuals randomly allocated into two groups: an experimental group (EG) with the application of 890 nm MIR associated with physical therapy and a control group that received the same treatment protocol without MIR application. Both groups underwent 18 treatment sessions and were followed up for 10 weeks. Pain assessment took place at four times using the instruments: Leeds Assessment of Neuropathic Symptoms and Signs, Douleur Neuropathique 4, and Brief Pain Inventory. Descriptive, inferential statistics and probabilistic estimates of the magnitude of the intervention's effect on neuropathic pain were used in data analysis (5% significance level)., Results: A total of 144 patients were allocated to groups. Lower levels of pain were observed for the EG after 6 weeks of intervention (p < .001) and 30 days after the intervention ended (p < .001). Pain intensity was lower and sleep quality improved (p < .001) for the experiment group, especially in people with severe pain., Conclusions: 890 nm MIR associated with a physical therapy protocol alleviated pain in people with Diabetic Painful Polyneuropathy after 6 weeks of follow-up, showing to be a promising alternative for the control of neuropathic pain due to diabetes mellitus., Clinical Implications: 890 nm MIR improves Painful Diabetic Polyneuropathy patient care due to relief of neuropathic pain., 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 article., (Copyright © 2024.

- Abstract
Glioblastoma (GB) is the most common type of malignant tumor of the central nervous system, responsible for significant morbidity and with a 5-year overall relative survival of only 6.8%. Without advances in treatment in the last twenty years, the standard of care continues to be maximum safe resection, Temozolomide (TMZ), and radiotherapy. Many new trials are ongoing, and despite showing increased progression-free survival, these trials did not improve overall survival. They did not consider the adverse effects of these therapies. Therefore, an increasing number of bioprospecting studies have used snake venom molecules to search for new strategies to attack GB selectively without producing side effects. The present review aims to describe GB characteristics and current and new approaches for treatment considering their side effects. Besides, we focused on the antitumoral activity of snake venom proteins from the Viperidae family against GB, exploring the potential for drug design based on in vitro and in vivo studies. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. In January 2024, a systematic search was performed in the PubMed, EMBASE, and Web of Science databases from January 2000 to December 2023. Search terms were selected based on the population/exposure/outcome (PEO) framework and combined using Boolean operators ("AND", "OR"). The search strategy used these terms: glioblastoma, glioma, high-grade glioma, WHO IV glioma, brain cancer, snake venom, Viperidae, and bioprospection. We identified 10 in vivo and in vitro studies with whole and isolated proteins from Viperidae venom that could have antitumor activity against glioblastoma. Studies in bioprospecting exploring the advantage of snake venom proteins against GB deserve to be investigated due to their high specificity, small size, inherent bioactivity, and few side effects to cross the blood-brain barrier (BBB) to reach the tumor microenvironment., Competing Interests: Competing of interests: All authors declare they have no conflict of interest.

We describe, illustrate and diagnose two hitherto unknown females of the genus Epipleoneura Williamson, 1915: E. capilliformis (Selys, 1886) and E. albuquerquei Machado, 1964. Both females are diagnosed based on the prothoracic hind lobe morphology: in E. capilliformis, the hind lobe is trilobed, with an elevated median portion, unique within the known females of the genus. Females of E. albuquerquei have an entire, posteriorly oriented (i.e. not partitioned into additional lobes) hind lobe, similar to E. haroldoi Santos, 1964, although more concave.

- Abstract
Background: Cardiometabolic diseases cover a spectrum of interrelated conditions linked to metabolic dysfunctions and/or cardiovascular disorders, including systemic arterial hypertension, diabetes mellitus, dyslipidemia, and obesity. Cocoa is a rich source of dietary polyphenols and has been associated with cardiovascular health benefits. However, beneficial effects of cocoa consumption and appropriate quantities in decreasing cardiometabolic risk factors have yet to be established. Therefore, we will conduct a systematic review and meta-analysis to examine the effects of cocoa consumption on cardiometabolic risk markers (total cholesterol, HDL, LDL, triglycerides, blood glucose, glycated hemoglobin, waist circumference, abdominal circumference, body mass index, systolic blood pressure and diastolic blood pressure) in adults with or without established cardiovascular risk factors., Methods: Our review will include all randomized controlled trials published in English, Portuguese and Spanish with no date of publication restrictions evaluating the effects of cocoa consumption on cardiometabolic risk markers selected from the databases MEDLINE (PubMed), LILACS, Cochrane, EMBASE, Web of Science and SciELO, and gray literature. Eligible studies must involve adults (age ≥18y), and the consumption of cocoa or dark chocolate (≥ 70% cocoa), include a control group and evaluate blood pressure, anthropometric measurements, and lipid or glycemic profiles. We will use risk-of-bias 2 (RoB2) tool to assess the risk of bias and the GRADE system to assess the strength of evidence. Statistical analyses will be performed using RStudio for Windows and R package meta., Discussion: This meta-analysis will summarize existing evidence on the effects of cocoa consumption on cardiometabolic health in adults. Better understanding the effects of cocoa consumption on anthropometric measurements, blood pressure, and lipid and glycemic profiles can provide valuable insights for health professionals to improve dietary recommendations regarding appropriate quantities., Trial Registration: Systematic Review Registration: PROSPERO CRD42023484490., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Arisi et al.

- Abstract
Background : Immune cells from rheumatoid arthritis (RA) patients display a reduced in vitro response to Porphyromonas gingivalis ( P. gingivalis ), which may have functional immune consequences. The aim of this study was to characterize, by flow cytometry, the frequency/activity of monocytes and naturally occurring myeloid dendritic cells (mDCs) in peripheral blood samples from patients with periodontitis and patients with periodontitis and RA. Methods : The relative frequency of monocytes and mDCs in the whole blood, the frequency of these cells producing TNFα or IL-6 and the protein expression levels for each cytokine, before and after stimulation with lipopolysaccharide (LPS) from Escherichia coli plus interferon-γ (IFN-γ), were assessed by flow cytometry, in peripheral blood samples from 10 healthy individuals (HEALTHY), 10 patients with periodontitis (PERIO) and 17 patients with periodontitis and RA (PERIO+RA). Results : The frequency of monocytes and mDCs producing IL-6 or TNF-α and the expression of IL-6 and TNF-α in the PERIO group were generally higher. Within the PERIO+RA group, P. gingivalis and related antibodies were negatively correlated with the monocyte and mDC expression of IL-6. A subgroup of the PERIO+RA patients that displayed statistically significantly lower frequencies of monocytes producing IL-6 after activation presented statistically significantly higher peptidylarginine deiminase (PAD)2/4 activity, anti-arg-gingipain (RgpB) IgG levels, mean probing depth (PD), periodontal inflamed surface area (PISA) and bleeding on probing (BoP). Conclusions : In the patients with PERIO+RA, innate immune cells seemed to produce lower amounts of pro-inflammatory cytokines, which are correlated with worse periodontitis-related clinical and microbiological parameters.
