RESUMO

Este trabalho teve como o objetivo comparar dois Projetos Políticos Pedagógicos, descrever e analisar o desenvolvimento da visão humanística no curso de graduação em Odontologia da Universidade Federal Fluminense, a partir da ótica dos acadêmicos do referido curso. Realizou-se uma pesquisa descritivo-exploratória com enfoque quanti-qualitativo. A coleta de dados deu-se em 03 etapas, as duas primeiras por meio de categorização dos fatores selecionados pelos alunos e a terceira pelo método denominado grupo focal. As estratégias de análises utilizadas foram a categorização, operações estatísticas simples, análise temática e análise crítica com a literatura revisada. Entre os resultados da pesquisa têm-se: não existe diferença entre a visão humanística dos alunos no período inicial quando comparada com as dos alunos no final do período do ciclo profissional no Projeto Pedagógico Antigo, no Projeto Pedagógico Novo, em curso, os alunos demonstram em sua maioria estar voltados para uma visão mais humanística. Conclui-se que a humanização, do processo ensino-aprendizagem no contexto acadêmico pesquisado, apresenta ainda deficiências, constituindo-se, portanto, em um caminho a perseguir, onde o comprometimento de todos os envolvidos neste processo de transformação e formação tem um papel fundamental.

The aim of this paper was to compare two Pedagogical Political Projects, to describe and analyze the development of humanistic vision in the undergraduate course in Dentistry of the Federal University of Fluminense, from the perspective of the academics of this course. A descriptive-exploratory research with quantitative-qualitative approach was carried out. The data collection took place in 03 stages; the first two by categorizing the factors selected by the students and the third by the method called the focal group. The analysis strategies used were categorization, simple statistical operations, thematic analysis and critical analysis with the reviewed literature. The results of the research are: there is no difference between the humanistic view of the students in the initial period when compared to the students at the end of the professional cycle in the Pedagogical Project. In the New Pedagogical Project, in progress, students demonstrate, in majority, aimed at a more humanistic view. It is concluded that the humanization of the teaching-learning process in the researched academic context still presents deficiencies, constituting, therefore, a path to be pursued, where the commitment of all those involved in this process of transformation and formation plays a fundamental role.

RESUMO

ABSTRACT Purpose: Myopia, or nearsightedness, is one of the most common eye conditions worldwide. However, a comparison of the effectiveness of different laser-assisted interventions is lacking. Thus, we aimed to compare the efficacy and safety of LASIK and IntraLASIK in addressing myopia. Methods: The study was conducted in two ophthalmology clinics in Beijing, China, in 2022. A total of 84 patients (152 eyes) with different degrees of myopia were examined and underwent LASIK (n=46, 80 eyes) or IntraLASIK (n=38, 72 eyes). Keratometry, corneal topography, pachymetry, visual acuity evaluation, and corneal biomechanical analysis were performed before and after the intervention. Results: IntraLASIK produced more precise flaps than LASIK, with deviations of <8 mm and 0.1 mm from the intended thickness and diameter, respectively. LASIK resulted in nonuniform flaps, with thickness deviations of 5-86 mm. IntraLASIK demonstrated a superior efficacy for patients with severe myopia and thin corneas, with a mean spherical equivalent of 0.9 D at 6 months compared to the 1.4 D for LASIK. Approximately 91% and 83% of the patients with mild to moderate and severe myopia, respectively, achieved results within ± 0.49 D from the refractive target with IntraLASIK. Conclusions: Corneal hysteresis and corneal resistance factor decreased with an increase in laser intensity, and they decreased faster with thinner corneas. Thus, IntraLASIK is more useful than LASIK in patients with thin corneas and severe myopia.

RESUMO

This brief review delves into the topic of in vitro follicle culture for in vitro embryo production, with a particular emphasis on goat models. Specifically, we examine the main findings from LAMOFOPA-Brazil over the last 20 years, highlighting the challenges posed by oxidative stress and epigenetic changes. Our focus is on strategies to improve follicular development and oocyte maturation. Furthermore, we underscore the valuable role of the antioxidant anethole in optimizing the efficacy of in vitro follicle culture and improving outcomes in in vitro embryo production.

RESUMO

In vitro produced embryos exhibit lower viability compared to their in vivo counterparts. Mammalian preimplantation embryos have the ability to reach the blastocyst stage in diverse culture media, showcasing considerable metabolic adaptability, which complicates the identification of optimal developmental conditions. Despite embryos successfully progressing to the blastocyst stage, adaptation to suboptimal culture environments may jeopardize blastocyst viability, cryotolerance, and implantation potential. Enhancing our capacity to support preimplantation embryonic development in vitro requires a deeper understanding of fundamental embryo physiology, including preferred metabolic substrates and pathways utilized by high-quality embryos. Armed with this knowledge, it becomes achievable to optimize culture conditions to support normal, in vivo-like embryo physiology, mitigate adaptive stress, and enhance viability. The objective of this review is to summarize the evolution of culture media for bovine embryos, highlighting significant milestones and remaining challenges.

RESUMO

OBJECTIVE: To investigate the effect of extremely brief meditation (EBMI) or brief mindfulness interventions (Brief MI) on pregnancy rate in women undergoing Assisted Reproductive Technology (ART). METHODS: This is a prospective, three-armed, randomized controlled trial with women undergoing ART cycle, age ranging from 18 to 50 years. In the day of embryo transfer, the patients randomized to Brief MI group received a 15-minute audio of mindfulness. They were instructed to practice it daily, starting from the day of embryo transfer to the day of the pregnancy test, leading to a total of 180-210 minutes. Women randomized to EBMI met once a week during the waiting time between the embryo transfer and pregnancy test day in the same virtual room with a meditator instructor for 40 minutes, totalizing two sessions (80 minutes). The pregnancy rate was assessed via a blood test to measure hCG performed 2 weeks after embryo transfer. RESULTS: A total of 68 women aged 37.5 ± 4.3y were included (EBMI, n = 24; Brief MI, n = 22 and CG, n = 22). Pearson's Chi-square test and Student's t-test for independent samples showed no significant differences between intervention and control groups. Both EBMI and Brief MI had no significant effect on pregnancy rate in women undergoing ART. CONCLUSION: This randomized control trial revealed that the extremely brief meditation (EBMI) or self-managed brief mindfulness intervention (Brief MI) had no significant effect on pregnancy rates in infertile women undergoing ART cycles. TRIAL REGISTRATION NUMBER: NCT04058262.

RESUMO

This study compared the influence of growth conditions on the composition and acidogenicity of saliva-derived microcosm biofilms and enamel demineralization. Biofilms grown in sucrose-supplemented modified McBain medium, containing 25/50 mmol/L PIPES (buffer), under anaerobiosis/microaerophilia, for 3 and 7 days were evaluated for their acidogenicity, microbial composition, matrix, and enamel mineral content. The viability of total lactobacilli was higher in the group containing 25 mmol/L PIPES grown under anaerobiosis, which also showed lower pH values. The viability of total streptococci and total microorganisms was significantly higher at 7 days in the groups with 50 mmol/L PIPES than at 3 days, regardless of the incubation atmosphere. No significant differences were observed in lactic acid, calcium, superficial hardness loss, or lesion depth. In conclusion, the incubation atmosphere, buffer content in the growth media, and duration of biofilm formation displayed species-varied influence on microcosm biofilms, without causing significant changes in acid metabolism or enamel demineralization.

RESUMO

AIMS: This systematic review aimed to assess the impact of oral health training for caregivers of individuals with disabilities. MATERIALS AND METHODS: A systematic review was conducted using five electronic databases: Medline (PubMed), SciELO, Web of Science, LILACS, and CAFe, adhering to PRISMA guidelines. The PICO strategy was defined as follows: Participants: caregivers of individuals with disabilities; Intervention: training or education in oral health for caregivers; Control: no caregiver training; and Outcomes: evaluating whether oral health training for caregivers improves the oral health of people with disabilities. The study aimed to address the research question: "What is the impact of oral health training for caregivers of individuals with disabilities?" The study was preregistered in PROSPERO (CRD42023416760). RESULTS: A total of 14 studies were included, with trained caregivers being either staff members or parents, and various disabilities reported, with cerebral palsy being the most prevalent. Caregiver training methods varied, such as instructions on the importance of oral health care, supervised oral hygiene, and demonstration of toothbrushing techniques. Overall, the intervention groups showed an improvement in measures such as to the Gingival Index, Plaque Index, Simplified Oral Hygiene Index, and Gingival Bleeding Index on upon probing. Additionally, improvements were observed in the quality, frequency, and duration of toothbrushing among intervention groups. CONCLUSION: The findings suggest that oral health training for caregivers has a positive impact on the oral health of individuals with disabilities, potentially leading to better oral health outcomes.

RESUMO

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-MSn 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.

RESUMO

The work reported in the Research Communication investigated in vitro rumen gas kinetics and fermentation profile as well as in vivo performance of lactating ewes fed corn silage (CS), sunflower silage (SFS) and their 50 : 50 mixture (CS-SFS). For the in vivo experiment, nine early-lactation Suffolk × Texel ewes were grouped in a replicated 3 × 3 Latin square design of three 21-d periods. Treatments were based on ad libitum CS, SFS, and CS-SFS supplemented with concentrate at 48 g/kg LW0.75. In vitro results showed that the CS had the highest dry matter degraded substrate and microbial crude protein production followed by CS-SFS. The in vivo data showed that animals fed on CS had higher digestibility of dry matter and organic matter than CS-SFS, while SFS were intermediate. Nitrogen (N) intake, fecal N excretion, and urine N excretion were similar between groups, however, milk N excretion was lower in SFS than CS. Milk yield was higher for CS and CS-SFS than SFS group, however, SFS-fed ewes had higher milk fat content than either CS or CS-SFS (all differences reported here were significant, P < 0.05 or better). Overall, CS-SFS could be used as dietary roughage for dairy ewes without deleterious effects on nutrient intake, N-balance and milk yield whilst potentially offering a more sustainable alternative to CS.

RESUMO

In Latin America, prostate cancer is the third most common cancer overall and the most common in men, with the highest mortality rate of all cancers. In 2022, there were approximately 22,985 new prostate cancer cases and 61,056 deaths from prostate cancer in the region. Patients with metastatic disease that is resistant to cure by castration now have multiple therapeutic options, including poly-ADP ribose polymerase inhibitors. These treatment advances present new challenges, such as developing monitoring protocols for early detection of disease progression to castration resistance. The Americas Health Foundation organized a 3-day meeting with 8 regional oncologists and pathologists to create a paper on metastatic castration-resistant prostate cancer diagnosis and therapy, including the new poly-ADP ribose polymerase inhibitors. The panel examined metastatic castration-resistant prostate cancer in Latin America and recommended ways to improve patient care using published literature and their expertise. Gene mutations play an important role in prostate cancer development. Precision medicine innovations highlight the importance of genotyping DNA variants and tumor biomarkers for targeted treatment. Access to appropriate genetic testing is difficult, medications are available but expensive, and there is a lack of infrastructure and regulatory frameworks that prevent patients from benefiting from innovative therapies. The panel recommends developing a population database and biobank and creating tumor tissue collection, processing, and storage facilities. Multi-stakeholder collaboration is needed to integrate the information gathered, train staff, select target populations, improve patient accessibility, and reduce the cost burden of drugs, genetic counselors, and cancer geneticists in Latin America. Collaboration is essential among healthcare professionals, policymakers, patient advocacy groups, pharmaceutical companies, and international organizations to address these challenges and needs in Latin America.

RESUMO

BACKGROUND: In vitro bioequivalence studies are strictly limited to the comparison of dissolution performance to a reference drug. These studies are performed without considering the chemical similarity between the generic and reference drug formulations. This work has focused on developing a groundbreaking method based on the laser-induced breakdown spectroscopy (LIBS) technique for the in vitro bioequivalence determination of immediate-release solid oral dosage form generic drugs and as an alternative method for establishing the biowaiver of in vivo generic drug studies. RESULTS: The novel LIBS-based methodology to determine in vitro bioequivalence is fast, easy to perform, and can be carried out without the requirement of tedious and complicated sample pre-treatment, nor expensive instrumentals and reagents, almost directly on the drug samples. Furthermore, the proposed methodology demonstrated that it is enough to identify the spectrochemical similarity of the formulation between generic drugs to a reference drug through the chemometric study of their LIBS spectra, based on the determination of the differentiation and similarity factors, f1 and f2, respectively, used in the pharmaceutical industry in this purpose. After analysing their LIBS spectra, the generic drugs selected for this work have all been shown to be in vitro bioequivalent, given their f1 values of less than 15 and f2 values greater than 50, according to the technical regulations on which the American and European medicines agencies are based for the approval of registration for generic immediate-release solid oral dosage form drugs. This has been evidenced even for drugs from Class III and Class IV of the biopharmaceutical classification system, whose active principle nominal concentration is very low as 0.1 and 0.25 mg/tablet, respectively. SIGNIFICANCE: for the first time the LIBS technique has been successfully used in an advanced application for the pharmaceutical industry. The proposed method constitutes a reliable and specialized methodology for the establishment of formulation similarity between two drugs, without the requirement of separate identification of each of their components, which is a new and potential tool to determine the in vitro bioequivalence for generic immediate-release solid oral dosage form drugs.

RESUMO

In this paper, we have performed an in-depth study of the complete set of the satellite DNA (satDNA) families (i.e. the satellitomes) in the genome of two barley species of agronomic value in a breeding framework, H. chilense (H1 and H7 accessions) and H. vulgare (H106 accession), which can be useful tools for studying chromosome associations during meiosis. The study has led to the analysis of a total of 18 satDNA families in H. vulgare, 25 satDNA families in H. chilense (accession H1) and 27 satDNA families in H. chilense (accession H7) that constitute 46 different satDNA families forming 36 homology groups. Our study highlights different important contributions of evolutionary and applied interests. Thus, both barley species show very divergent satDNA profiles, which could be partly explained by the differential effects of domestication versus wildlife. Divergence derives from the differential amplification of different common ancestral satellites and the emergence of new satellites in H. chilense, usually from pre-existing ones but also random sequences. There are also differences between the two H. chilense accessions, which support genetically distinct groups. The fluorescence in situ hybridization (FISH) patterns of some satDNAs yield distinctive genetic markers for the identification of specific H. chilense or H. vulgare chromosomes. Some of the satellites have peculiar structures or are related to transposable elements which provide information about their origin and expansion. Among these, we discuss the existence of different (peri)centromeric satellites that supply this region with some plasticity important for centromere evolution. These peri(centromeric) satDNAs and the set of subtelomeric satDNAs (a total of 38 different families) are analyzed in the framework of breeding as the high diversity found in the subtelomeric regions might support their putative implication in chromosome recognition and pairing during meiosis, a key point in the production of addition/substitution lines and hybrids.

RESUMO

Background: With increasing healthcare service utilization and the introduction of costly therapies, healthcare organizations are pressured to deliver cost-effective services within constrained budgets. Rising costs and the need for efficient healthcare delivery are major concerns for governments, insurers, and health plans. Objectives: It aims to understand the impact of these intangible assets on creating value and organizational resilience in healthcare, informing better practices and strategies for VBHC implementation. Methods: An applied research approach using the Work Breakdown Structure (WBS) methodology was adopted. The research was divided into seven interconnected Work Packages (WPs), each designed to investigate different aspects of the integration between VBHC and intangible assets, with a focus on enhancing organizational resilience through innovative health processes. Key methodologies included literature reviews and qualitative analyses, employing Open Innovation and Design Thinking. Results: The study revealed a dynamic interplay between VBHC, organizational resilience, and intangible assets. It showed that managerial effectiveness is influenced by direct patient outcomes and elements like intellectual capital and organizational reputation. Data integration from various Work Packages provided new insights into how intangible assets underpin VBHC strategies, proposing novel management approaches. Findings highlight the essential role of intangible assets in enhancing service delivery and fostering sustainable healthcare practices. Discussion: The study highlights a significant oversight in the integration of intangible assets within healthcare organizations, despite their crucial role in optimizing VBHC. It supports literature emphasizing the importance of intellectual capital and organizational culture in enhancing healthcare management efficiency and resilience. A paradigm shift in VBHC to include these assets is needed for building a more adaptable and sustainable healthcare system. This integration can lead to better clinical outcomes, patient satisfaction, and overall healthcare efficiency, aligning more closely with VBHC goals. Conclusion: Recognizing and effectively managing intangible assets are paramount for the successful implementation of VBHC and enhanced organizational resilience. Strategic integration of these assets into healthcare management practices can significantly improve patient outcomes and create a more sustainable, patient-centered, and resilient healthcare system. Future studies should develop methodologies for robust measurement and integration of these assets to fully realize the potential of VBHC.

RESUMO

Gamma-decanolactone (GD) is a monoterpene compound with anticonvulsant, antiparkinsonian, and neuroprotective effects in preclinical trials. This study aimed to evaluate the toxicity and antioxidant profile of GD in silico and in the Caenorhabditis elegans (C. elegans) experimental model. The C. elegans was used to determine the median lethal concentration (LC50) of GD, as well as its effect on survival, development, reproduction, pharyngeal pumping, and stress resistance assays. The in silico study did not indicate hepatotoxic, cardiotoxic, or mutagenic potential to GD. It reduced the worms' survival, both at the L1 and L4 stages, in a concentration-dependent manner with an LC50 value of 212.16 ± 5.56 µmol/mL. GD did not alter the development, reproduction, and pharyngeal pumping under normal experimental conditions in the three concentrations tested (25, 50, and 100 µmol/mL). In the thermal stress assay, GD did not change the survival pattern of the worms. Hydrogen peroxide (H2O2) reduced the survival of C. elegans and decreased the number of pharyngeal pumping, with these effects being reversed by GD. Also, GD presents an antioxidant activity by modulation the expression of the stress response genes such as sod-3, ctl-1,2,3, and gst-4. In conclusion, GD showed low toxicity in the C. elegans model and antioxidant profile both in the in silico study and in vivo assays.

RESUMO

The waterpipe works by placing tobacco in a bowl with holes at the bottom, which is connected to a tube leading to a water-filled container. Upon heating the tobacco product with hot charcoal placed atop it, the emanating smoke is inhaled by the user via a hose linked to the water receptacle. The aim of this literature review is to evaluate whether the use of waterpipes can indeed induce genotoxicity in mammalian cells in vivo. Additionally, the study aims to assess the quality of the included research articles on this topic to ensure the reliability of the findings. We performed comprehensive searches in PubMed, SCOPUS, and Web of Science to identify relevant articles published until July 2024. The findings confirmed that waterpipe smoke induces genetic damage. This assertion is supported by the fact that 11 studies (out of 15) received a Strong or Moderate assessment categorization, suggesting that the majority of studies adhered to most technical standards, thereby enhancing the reliability of the research findings. Regarding the types of DNA damage reported, DNA strand breaks, chromosome damage and oxidative DNA damage were found in this review. Taken together, this study holds significant importance in assessing the efficacy of genotoxicity assays in detecting DNA damage due to waterpipe smoke and the comet and micronucleus assays are suitable biomarkers for biomonitoring people who use waterpipe.

RESUMO

Aging is a universal and progressive process involving the deterioration of physiological functions and the accumulation of cellular damage. Gene regulation programs influence how phenotypes respond to environmental and intrinsic changes during aging. Although several factors, including sex, are known to impact this process, the underlying mechanisms remain incompletely understood. Here, we investigate the functional organization patterns of skeletal muscle genes across different sexes and ages using gene co-expression networks (GCNs) to explore their influence on aging. We constructed GCNs for three different age groups for male and female samples, analyzed topological similarities and differences, inferred significant associated processes for each network, and constructed null models to provide statistically robust results. We found that each network is topologically and functionally distinct, with young women having the most associated processes, likely due to reproductive tasks. The functional organization and modularity of genes decline with age, starting from middle age, potentially leading to age-related deterioration. Women maintain better gene functional organization throughout life compared to men, especially in processes like macroautophagy and sarcomere organization. The study suggests that the loss of gene co-expression could be a universal aging marker. This research offers insights into how gene organization changes with age and sex, providing a complementary method to analyze aging.
