title: Carious lesions recurrence in children with developmental disabilities: a longitudinal study

description: Abstract This study investigated the factors associated with new carious lesions in one-to five-year-old children with developmental disabilities. This was a retrospective cohort that evaluated 64 dental charts of individuals with caries or fillings in their first dental appointment. The dependent variable was the occurrence of a new carious lesion or restoration. Gender, age, mother’s education, sugar consumption, oral hygiene, mouth breathing, reports of xerostomia, gingival status, use of psychotropic drugs, use of asthma drugs, history of asthma, bronchitis, reflux or seizures and having at least one sibling were covariates. Cox proportional hazards regression model was used to estimate the raw and adjusted hazard ratios with their respective 95% confidence interval. The average time that individuals remained free of dental caries/restoration was 79.49 months (95%CI: 64.37 to 92.61). Increase in sucrose consumption increased the rate of caries recurrence (HR = 1.16; 95%CI: 1.04 to 1.30). Individuals who had poor oral hygiene had higher rate of new dental caries (HR = 3.88; 95%CI: 1.22 to 12.37) compared to those with good oral hygiene. The presence of mouth breathing decreased the rate of recurrence of the disease when compared to the nasal breathing (HR = 0.32; 95%CI: 0.15 to 0.70). Oral health-related behaviors and nasal respiration influenced the rate of dental caries recurrence in individuals with developmental disabilities.

title: Global publication trends in ophthalmic genetics and gene therapy research: A Scientometric analysis

description: ABSTRACT Objective: A scientometric analysis produced in ophthalmic genetics and gene therapy research is lacking. The purpose of this study is to present a holistic analysis of ophthalmic genetics literature. Methods: The data used in this study were obtained from the Web of Science (WoS) Core Collection. All published documents between 1975-2019 were included. The data exported from WoS enabled the extensive details of ophthalmic genetics related literature including countries, institutions, authors, citations and keywords. Scientometric network maps of keywords and also country and institution co-authorships were created with free software. Global contributions of the countries to the ophthalmic genetics literature were shown by a graphic. Results: The search query revealed a total of 2322 documents. Most of the documents were original articles (75.75%). USA was the leading country by producing 45.39% of all documents in ophthalmic genetics research followed by UK, Germany, China and France. Pennsylvania University was the most contributing institution in the literature (5.25%) followed by University College London and Moorfields Eye Hospital. The average citations per item was 29.4. The most used keywords over a 40-year period were 'family', 'cell', 'photoreceptor' and 'expression'. Conclusions: USA and UK dominated the ophthalmic genetics research. A substantial increase in the number of published documents in this field were observed after 2010.

title: Cardiac Arrhythmias and Covid-19

description: Abstract Cardiovascular manifestations of COVID-19 include cardiac rhythm disturbances, whose mechanisms, incidence, and most common types are not well established in this population. Intense inflammatory response and metabolic activity contribute to recurrence of pre-existing arrhythmias, and other arrhythmias can occur due to myocardial injury, acute coronary insufficiency, and electrolyte disturbances. Brady- and tachyarrhythmias, as well as conduction disorders have been described. QT interval prolongation and fatal ventricular arrhythmias ( Torsades de Pointes ) may result from the pathological process or adverse effect of drugs (antiarrhythmics, chloroquine / hydroxychloroquine, azithromycin and antivirals). Patients with congenital heart disease and hemodynamic repercussions, patients with signs of heart failure, pulmonary hypertension, cyanosis, hypoxemia, and those who underwent heart transplantation and immunosuppression are at greater risk. In patients with implantable cardioverter-defibrillators (ICDs), the risk depends on the presence of structural heart disease. In the course of COVID-19, in-person assessment of these patients should be limited to high-risk situations, including syncope, worsening of heart failure and shock delivery by ICDs. Likewise, cardiac implantable electronic device implantation or replacement surgery should be limited to emergency and urgent cases, including symptomatic high-degree atrioventricular block, ICD for secondary prevention and pulse generator replacement due to battery drain.

title: Historical construction of the concept of the enzyme and approaches in biology textbooks

description: Abstract The use of the history and philosophy of science in teaching and learning is commonly neglected, linear, and/or out of context in textbooks. This article investigates whether this also occurs with the concept of enzymes. A brief review of the literature establishes the theoretical foundation to investigate how the concept of enzymes is presented in nine textbooks, following three different lines of analysis. A general lack of interconnection was seen in biochemistry topics, with enzymes usually only presented via the “lock-and-key” model, which does not best represent their complexity. Furthermore, conceptual limitations resulting from a lack of historical contextualization (partial or complete) were also observed.

title: Recurrent pterygium resection associated to fibrin membrane graft: report of two cases

description: ABSTRACT We propose a novel surgical technique in cases of aggressive recurrent pterygium non-subsidiary of treatment with conjunctival autografts or antimetabolites. Two presented cases were treated with surgical excision and a sutured plasma rich in growth factors membrane (mPRGF) followed by rich in growth factors (PRGF) eye drops treatment. After surgery, dexamethasone, tobramycin and PRGF eye drops were prescribed for 6 weeks. After a 12-month and 3-year post-surgical follow-up respectively, treated eyes with mPRGF did not present relapse, and visual acuity improved in both cases. No ocular complications, pain, eye discomfort nor other symptoms were observed. The combined use of PRGF eye drops and mPRGF seems an effective and safe therapy for recurrent pterygium.

title: Risk factors for dental caries in Latin American and Caribbean countries

description: Abstract Identifying the risk factors for dental caries is vital in epidemiology and clinical practices for developing effective preventive strategies, both, at the individual and collective levels. Different causality/determination models have been proposed to understand the development process of dental caries. In the present review, we designed a model inspired by the world-known social determinants models proposed in the 90s and more recently in the 10s, wherein the contextual factors are placed more externally and encompass the individual factors. The contextual factors included those related to the cultural and societal values, as well as the social and health government policies. The individual factors were classified into the following categories: socioeconomic (social class, occupation, income, and education level), demographic characteristics (age, sex, and ethnicity), behavioral factors (non-use of fluoride dentifrice, sugar consumption, poor oral hygiene, and lack of preventive dental care), and biological factors (recent caries experience/active caries lesions, biofilm retentive factors, developmental defects of the enamel, disabilities, saliva amount and quality, cariogenic biofilm). Each of these variables was addressed, while focusing on the current evidence from studies conducted in Latin American and Caribbean countries (LACC). Based on the proposed model, educational aspects were addressed, and individual caries risk assessment and management decisions were proposed; further, implications for public health policies and clinical practice were described. The identification of modifiable risk factors for dental caries should be the basis for multi-strategy actions that consider the diversity of Latin American communities.

title: A Metabolomics-based strategy to assess drug hepatotoxicity and uncover the mechanisms of hepatotoxicity involved

description: Toxicity studies, among them hepatotoxicity, are key throughout preclinical stages of drug development to minimize undesired toxic effects that might later appear during the clinical use of a new drug. Here, we envisage an innovative strategy to identify potential hepatotoxic drugs and uncover the mechanisms of toxicity. This strategy was based on the analysis of metabolome changes induced by hepatotoxic and non-hepatotoxic compounds in HepG2 cells, assessed by untargeted mass spectrometry. As a training set we used 25 hepatotoxic and 4 non-hepatotoxic compounds and incubated HepG2 cells for 24 h at a IC10 and IC50 concentration to identify metabolomic toxicity biomarkers and elaborate prediction models accounting for global hepatotoxicity and toxicity mechanisms. Thereafter, a second set of 69 chemicals with known predominant mechanisms of toxicity and 18 non-hepatotoxic compounds were analysed at 1, 10, 100 and 1000 µM concentrations from which, based on the magnitude of the alterations caused as compared with non-toxic compounds, we defined a “<em>toxicity index</em>” for each compound. In addition we extracted from the metabolome data the characteristic signatures for each mechanism of toxicity.

title: Armed conflict, disease and death: health in the Caste War (Yucatán, Mexico) in the second half of the nineteenth century

description: Abstract An analysis of the relationship between health and war in the context of the Caste War in Yucatan, Mexico, during the second half of the nineteenth century. Using qualitative and quantitative sources, this article reconstructs the main critical health events and argues that the health/disease process at the time can necessarily only be explained in relation to variables connected to the conflict, such as arms trafficking, displacements, diasporas and migrations, food shortages, violence and administrative chaos.

title: Evaluation of visual function and vision-related quality of life in patients with senile cataract

description: ABSTRACT Purpose: To investigate the correlation between quality of life and decreased visual acuity in elders with senile cataract. Methods: A transversal and quantitative study involving 53 elderly patients with senile cataracts and candidates for cataract surgery in a private ophthalmology clinic in Montes Claros, Minas Gerais. For sociodemographic investigation, a questionnaire elaborated by the authors was used. Research on visual-related quality of life was done through the National Eye Institute - Visual Function Questionnaire 25 (NEI-VFQ 25) questionnaire. For statistical analysis, Pearson's correlation coefficient and hypothesis testing were applied, in which the test statistic follows a Student's t distribution, with 5% significance level (p &lt; 0,05). Results: The majority of the interviewed patients' ages were comprehended between 70 and 79 years old (n.29 / 54,7%) and were female (n.30 / 56,6%). The correlation between the mean score of the "Visual Capacity" domain and of the "Quality of Life" domain had Pearson's correlation coefficient equal to 0,664, statistically significant in Student's t-test (p &lt; 0,001). Therefore, there are evidences that the quality of life and the visual function are correlated so that the better the visual capacity, the better the quality of life. Conclusion: The correlation between ocular health and functional capacity of the elderly can be obtained by the application the National Eye Institute - Visual Function Questionnaire 25 (NEI-VFQ 25), generating data that reveals the necessity of guaranteed access to ocular health by the elderly population.
