Low HDL-C/ApoA-I index is associated with cardiometabolic risk factors and coronary artery calcium: a sub-analysis of the genetics of atherosclerotic disease (GEA) study.

BACKGROUND: The high-density lipoprotein cholesterol to apolipoprotein A-I index (HDL-C/ApoA-I) may be practical and useful in clinical practice as a marker of atherosclerosis. This study aimed to investigate the association between the HDL-C/ApoA-I index with cardiometabolic risk factors and subclinical atherosclerosis. METHODS: In this cross-sectional sub-analysis of the GEA study, 1,363 individuals, women (51.3%) and men (48.7%) between 20 and 75 years old, without coronary heart disease or diabetes mellitus were included. We defined an adverse cardiometabolic profile as excess adipose tissue metrics, non-alcoholic liver fat measured by non-contrasted tomography, metabolic syndrome, dyslipidemias, and insulin resistance. The population was stratified by quartiles of the HDL-C/Apo-AI index, and its dose-relationship associations were analysed using Tobit regression, binomial, and multinomial logistic regression analysis. RESULTS: Body mass index, visceral and pericardial fat, metabolic syndrome, fatty liver, high blood pressure, and CAC were inversely associated with the HDL-C/ApoA-I index. The CAC > 0 prevalence was higher in quartile 1 (29.2%) than in the last quartile (22%) of HDL-C/ApoA-I index (p = 0.035). The probability of having CAC > 0 was higher when the HDL-C/ApoA-I index was less than 0.28 (p < 0.001). This association was independent of classical coronary risk factors, visceral and pericardial fat measurements. CONCLUSION: The HDL-C/ApoA-I index is inversely associated with an adverse cardiometabolic profile and CAC score, making it a potentially useful and practical biomarker of coronary atherosclerosis. Overall, these findings suggest that the HDL-C/ApoA-I index could be useful for evaluating the probability of having higher cardiometabolic risk factors and subclinical atherosclerosis in adults without CAD.

Drugs targeting APOE4 that regulate beta-amyloid aggregation in the brain: Therapeutic potential for Alzheimer's disease.

Alzheimer's disease is characterized by progressive cognitive decline, and behavioural and psychological symptoms of dementia are common. The APOE ε4 allele, a genetic risk factor, significantly increases susceptibility to the disease. Despite efforts to effectively treat the disease, only seven drugs are approved for its treatment, and only two of these prevent its progression. This highlights the need to identify new pharmacological options. This review focuses on mimetic peptides, small molecule correctors and HAE-4 antibodies that target ApoE. These drugs reduce ß-amyloid-induced neurodegeneration in preclinical models. In addition, loop diuretics such as bumetanide and furosemide show the potential to reduce the prevalence of Alzheimer's disease in humans, and antidepressants such as imipramine improve cognitive function in individuals diagnosed with Alzheimer's disease. Consistent with this, both classes of drugs have been shown to exert neuroprotective effects by inhibiting ApoE4-catalysed Aß aggregation in preclinical models. Moreover, peroxisome proliferator-activated receptor ligands, particularly pioglitazone and rosiglitazone, reduce ApoE4-induced neurodegeneration in animal models. However, they do not prevent the cognitive decline in APOE ε4 allele carriers. Finally, ApoE4 impairs the integrity of the blood-brain barrier and haemostasis. On this basis, ApoE4 modulation is a promising avenue for the treatment of late-onset Alzheimer's disease.

Healthy Habits, Physical Activity, Stress, and Food Consumption Trends in Chilean Adults with Irritable Bowel Syndrome during the COVID-19 Pandemic.

The COVID-19 pandemic has increased stress levels in the population due to radical lifestyle changes caused by containment measures. Studies suggest that high levels of stress may be related to the development of irritable bowel syndrome (IBS). This study aims to explain how quarantine habits and lifestyles acted as risk factors for the frequency of this syndrome during the COVID-19 pandemic. An observational study was conducted with 34 Chilean participants (average age 24.5 ± 3.85 years), of whom 21 (62%) were female. Surveys on consumption trends and lifestyles created by the authors were administered. Additionally, we used the global physical activity questionnaire (GPAQ) and the depression anxiety stress scales (DASS-21) to assess psychological stress and the Rome IV criteria to assess IBS. Significant differences were found between individuals with better healthy habits compared to those with poor healthy habits. The former showed lower sedentary activity (32%, p = 0.005), only 27% were fast eaters (vs. 44%, p = 0.001), had shorter nap intervals (14% vs. 28%, p = 0.03), and higher vegetable consumption (p = 0.02). There were 20 cases (59%) of IBS, with a strong association with the female sex (p = 0.004), where females were 15 times more likely to develop it compared to males (p = 0.008). Additionally, when alcohol consumption was added to females, there was a higher likelihood of developing this syndrome (p = 0.009), as individuals who consumed alcohol were 12 times more likely to develop it compared to those who did not (p = 0.02). Among other factors, it was observed that 57% of those with the syndrome consumed drinks more often (p = 0.02) but consumed fewer nuts (p = 0.009). In conclusion, IBS has a multifactorial etiology, and correcting individual habits such as alcohol consumption could potentially prevent or delay its development. Therefore, it is important to maintain healthy lifestyles, regardless of non-modifiable factors such as gender, in order to better cope with this syndrome.

Analysis of dietary fats intake and lipid profile in Chilean patients with glucose transport type 1 deficiency syndrome: similarities and differences with the reviewed literature.

Introduction: Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is a neurological disorder caused by mutations in the SLC2A1 gene. The main treatment is ketogenic diet therapy (KDT), which changes the brain's energy substrate from glucose to ketone bodies. The diet controls seizures, but there may be side effects such as dyslipidemia. This study aimed to describe the type of fats ingested by the Chilean cohort of patients with GLUT1-DS and analyze for alterations in the lipid profile. Methods: A GLUT1-DS group and a control group were formed, each with 13 subjects who were matched by age, gender, and nutritional status. Anthropometry, dietary intake, including types of fat, and blood tests were evaluated (lipid and liver profile, and 25-hydroxyvitamin D levels). Results: A high-fat diet, especially saturated fat, was identified in the GLUT1-DS group (38% of total calories), with the use of medium-chain triglycerides (17% of total calories). In addition, GLUT1-DS participants had a higher intake of monounsaturated (MUFA) and polyunsaturated (PUFA) fats and adequate consumption of omega-3 (2% of total calories). Despite the GLUT1-DS group receiving on average 80% of its total energy as fats, it is important to highlight that 50% are MUFA+PUFA fats, there were no significant differences in the lipid and liver profile compared to the control group. Conclusion: KDT did not negatively impact lipid profile, despite a high intake of fats. It is important to monitor lipid profiles, in a personalized and constant manner, to prevent future nutritional risks.

Vaginal stenosis and dilator use after pelvic brachytherapy

Introduction: To prevent vaginal stenosis, the use of a vaginal dilator is recommended. Objective: To analyze sociodemographic data, gynecological conditions and the use of vaginal dilator after pelvic brachytherapy. Materials and Methods: Cross-sectional, retrospective study, period 2016-2020, collected between October/2020 and February /2021, from records of women with gynecological cancer treated with brachytherapy at the Centro de Pesquisa Oncológicas (Brazil). The variables included sociodemographic data and gynecological conditions in following the treatment. In the analysis, descriptive statistics, chi-squaretest, Fisher's exact test and Mann-Whitney test were applied. Results: 519 patients records were included in the investigation; the analyzes showed significant associations between the topography and staging (p<0.001), education (p=0.004) and age (p<0.001); the comparison between the distribution of the ionizing radiation dose showed a difference with the continued sexual relationship category (p=0.006); the comparison between the proportions of continued sexual relationship and using a vaginal dilator was significant (p<0.001); 49.10% (131) adhered to the use of vaginal dilator; 24.50% (127) are not sexually active and do not adhere to the use of the dilator. Discussion: It is evident that social and gynecological conditions interfere with the presence of vaginal stenosis and the use of a vaginal dilator after pelvic brachytherapy. Conclusions: The adherence found in the use of dilator affirms the contributions and the need for health education by nurses and physicaltherapists during and following the treatment.

Impact of Pre-Gestational BMI and Gestational Weight Gain on Fetal Development Outcomes in Adolescent Pregnant Women.

Background. Gestational weight gain (GWG) constitutes an essential aspect of the gestational process. Due to factors such as pregestational body mass index (BMI), nutritional intake, level of physical activity, and psychological aspects, the recommended GWG may not be achieved, leading to adverse neonatal outcomes. Adolescents, due to their physiological and mental developmental stage, are at a higher risk of inappropriate GWG. Our aim is to highlight the importance of GWG in our population and to determine the correlation with perinatal outcomes. Methods. Pregnant adolescents who attended a tertiary care institution for prenatal care were included; maternal data such as preBMI and GWG were used to determine maternal and neonatal outcomes using the chi-square test and OR determination. Results. A total of 202 adolescent pregnant patients were included, comprising those with inadequate GWG (n = 70), adequate GWG (n = 85), and excessive GWG (n = 47). A statistically significant association was found between low BMI and inadequate GWG. Patients with inadequate GWG demonstrated a correlation with IUGR and low birth weight, while patients with excessive GWG gave birth to macrosomic neonates. Conclusion. We concluded that previous habits play a significant role in determining weight gain throughout pregnancy. GWG has a direct impact on neonatal growth and development.

Measurement of elements by portable x-ray fluorescence spectrometry for the study of adsorption processes: the case of Pb2+adsorption on soybean straw biochar.

This study evaluated the reliability of portable X-ray fluorescence (pXRF) in Pb2+adsorption kinetics and isotherm experiments using soybean straw biochar. The research aimed to compare pXRF results with those obtained through traditional atomic absorption spectrometry (AAS). Soybean straw biochar, produced at 400 °C, was employed as the adsorbent for Pb2+. The efficiency of adsorption was assessed using Langmuir and Freundlich models. The kinetics of Pb2+adsorption was analysed through pseudo-first-order and pseudo-second-order models. The pseudo-second-order model described the kinetics of Pb2+adsorption on biochar better than the pseudo-first order model. Importantly, the pXRF technique demonstrated comparable results to those of AAS, making it a reliable and resource-efficient method for studying Pb2+kinetics. The results of the isotherm analyses fit the Langmuir model, indicating a desirable and irreversible adsorption of Pb2+on biochar. PXRF measurements on biochar allowed simultaneous observations of Pb2+adsorption and K+and Ca2+desorption, highlighting ionic exchange as the primary adsorption mechanism. In conclusion, our results showcased the applicability of pXRF for Pb+2adsorption studies in biochars, offering a valuable alternative to traditional methods. The findings contribute to the understanding of biochar as an effective adsorbent for heavy metals, emphasizing the potential of pXRF for cost-effective and efficient environmental research. In this study, we present a novel and detailed procedure that will allow other researchers to continue their studies on Pb2+adsorption on biochar or similar matrices, significantly reducing the resources and time used and enabling the simultaneous study of the behavior of other ions participating in the process.

Isolation of total DNA from Placenta Samples, both Fresh and following Formalin and Paraffin Treatment.

The isolation of DNA from placental tissue suspected of infection is an important tool for identifying microorganisms such as bacteria, fungi, and viruses associated with complications during and after pregnancy. While experts primarily process placental tissue, the preservation methods employed pose challenges to extracting complete DNA. Therefore, selecting the appropriate protocol is paramount to achieving greater efficiency in obtaining genetic material.

Assessing empathy in healthcare services: a systematic review of South American healthcare workers' and patients' perceptions.

Background: Empathy in healthcare service refers to the ability of healthcare workers (HCWs) to put themselves in patients' shoes, which is necessary to ensure a good physician-patient relationship and provide quality care. Various studies have shown that empathy varies depending on the country, the instrument used, the evaluator, and the HCW's specialty. This systematic review aims to estimate the levels of empathy among HCWs in South American countries between 2000 and 2019. Methods: We conducted searches in 15 databases (PubMed, Scopus, Web of Science, EMBASE, Scielo, PsycoInfo, ScientDirect, Latindex, and LILIACS), four preprint servers (medRxiv, bioRxiv, SportRxiv, and Preprints), and other search engines such as Dimensions (20), Google Scholar, Yahoo!, and Alicia CONCyTec (c). We followed the PRISMA guidelines, and this study was registered in PROSPERO (CRD42023454007). Results: Out of 18,532 documents identified from November 10 to 28, 2021, 10 articles were included (n = 2,487 participants, of which 1989 were patients). Among the studies focusing on self-evaluated empathy, four relied on the Jefferson Scale of Empathy for medical professionals (JSE-HP). However, assessments from patients employing Jefferson Scale of Patient's Perceptions of Physician Empathy (JSPPPE) and Consultation and Relational Empathy (CARE) scale suggested high levels of empathy We found that both professionals and patients perceived that empathic care was provided, often at a medium or regular level. Surgery residents presented lower levels of empathy compared to obstetrics-gynecology and pediatrics physicians. Conclusion: Empathy is crucial in determining the quality of care and patient satisfaction during healthcare services provided by HCWs. Therefore, it is important to support professionals so that the various stressful situations they encounter in their work and daily life do not negatively influence the approach they provide to patients.

Mycorrhizal fungal communities associated with three metal accumulator plants growing in an abandoned Pb smelting factory.

Plants associated with mycorrhizal fungi has the ability to establish on metal-contaminated soils playing an important role in phytoremediation programs. The objective of this study was to examine the presence of arbuscular mycorrhizal fungi (AMF) (spores density, diversity, indicator species, and root colonization) and dark septate endophytic fungi (DSE fungal root colonization) in three metal accumulator plants (Sorghum halepense, Bidens pilosa, and Tagetes minuta) growing in soils with high Pb content. The Pb content in AMF spores and plant biomass were also assessed. Rhizosphere soil samples were taken from the three dominant plant species at six study sites surrounding the abandoned Pb smelter and one uncontaminated site. The three studied plants were colonized by AMF and DSE fungi. A total of 24 AMF morphospecies were present in the Pb-contaminated areas. The AMF indicator species in the control site (non-contaminated area) was Funneliformis mosseae and in the most contaminated site were Gigaspora decipiens and Denticustata biornata. There was an increase in mycorrhizal variables such as the number of AMF vesicles, spore number, Pb content in AMF spores and plant biomass and DSE colonization (in Sorghum) with increasing soil Pb contamination, but a decrease in AMF diversity and richness was found. For upcoming soil restoration projects, it is crucial to understand the mycorrhizal fungi as well as the plant community that has adapted to the highly contaminated environment.

The association between hypoalbuminemia and microcirculation, endothelium, and glycocalyx disorders in children with sepsis.

OBJECTIVE: The objective of this study was to evaluate the association between serum albumin levels and microcirculation changes, glycocalyx degradation, and the clinical outcomes of interest. METHODS: Observational, prospective study in children with sepsis. The primary outcome was the association between hypoalbuminemia and microcirculation disorders, endothelial activation and glycocalyx degradation using a perfused boundary region (PBR) (abnormal >2.0 µm on sublingual video microscopy) or plasma biomarkers (syndecan-1, angiopoietin-2). RESULTS: A total of 125 patients with sepsis were included. The median age was 2.0 years (IQR 0.5-12.5). Children with hypoalbuminemia had more abnormal microcirculation with a higher PBR (2.16 µm [IQR 2.03-2.47] vs. 1.92 [1.76-2.28]; p = .01) and more 4-6 µm capillaries recruited (60% vs. 40%; p = .04). The low albumin group that had the worst PBR had the most 4-6 µm capillaries recruited (rho 0.29; p < .01), 48% higher Ang-2 (p = .04), worse annexin A5 (p = 0.03) and no syndecan-1 abnormalities (p = .21). Children with hypoalbuminemia and a greater percentage of blood volume in their capillaries needed mechanical ventilation more often (56.3% vs. 43.7%; aOR 2.01 95% CI 1.38-3.10: p < .01). CONCLUSIONS: In children with sepsis, an association was found between hypoalbuminemia and microcirculation changes, vascular permeability, and greater endothelial glycocalyx degradation.

Cytokine and microbiota profiles in obesity-related hypertension patients.

Background: Systemic arterial hypertension is linked to a heightened risk of cardiovascular diseases on a global scale. In Mexico, nearly half of adults in vulnerable conditions experience hypertension. Imbalance in the oral and intestinal microbiota composition has been observed in patients with hypertension, documented by a decrease of bacteria producing short-chain fatty acids, which play a critical role in blood pressure regulation. Aim: To examine the cytokines' profile and assess the characteristics of oral and gut microbiota in obesity-related hypertension in Mexican patients. Methods: A cross-sectional, observational, and analytical study was carried out. Twenty-two patients were categorized by their body mass index (BMI) as overweight and obese, and the diagnosis of primary hypertension. DNA from supragingival dental plaque and feces samples was used to carry out 16S rRNA sequencing. Additionally, 13 cytokines were quantified. Results: In the oral microbiota, Kluyvera was found to be significantly enriched in obese compared to overweight patients. Instead, the gut microbiota was dominated by Firmicutes. However, the correlation between certain genera and proinflammatory cytokines was noted. Conclusion: This exploratory study provides insights into the complex relationship between the oral and gut microbiota and their association with systemic inflammation in obesity-related hypertension.

Métodos: Foram aplicados os critérios de relatório PRISMA-SCR. Os bancos de dados pubmed/Medline, Elsevier, Epistemonikos, Scielo.org, Redalyc.org, Imbiomed e google artigos acadêmicos, em inglês e espanhol publicados de janeiro de 2017 a junho de 2022 foram usados para pesquisar artigos. Foram selecionados 15 artigos que cumpriam os critérios de inclusão estabelecidos para a revisão. Resultados: 60,0 % dos estudos relataram que a instrumentação rotativa tinha melhor qualidade de obturação do que a instrumentação manual; 40,0 % relataram não encontrar diferença estatisticamente significativa entre as duas técnicas. 100% dos estudos indicaram que houve uma redução significativa no tempo de instrumentação dos arquivos rotativos em comparação com os arquivos manuais. Conclusão: As evidências indicam que tanto a instrumentação rotativa quanto a manual, estão sendo eficazes para garantir a qualidade da obturação dos canais radiculares e que o tempo de instrumentação é menor com a instrumentação rotativa. Este aspecto é muito importante na odontologia pediátrica, pois reduz o tempo de tratamento e contribui para que a criança seja mais cooperativa e os tratamentos sejam mais eficazes

Introduction: In pulp therapy, there have been advances that are not only related to the biomaterials used but also to the techniques used for instrumentation; hence, optimizing the latter contributes to increasing the quality of therapeutics in this field. Objective: to examine the available evidence on rotary instrumentation vs. manual instrumentation for pulp therapy in pediatric dentistry. Methods: PRISMA-ScR reporting criteria were applied. For the search of the articles, the pubmed/medline, Elsevier, Epistemonikos, Scielo.org, Redalyc.org databases were used; Imbiomed and academic google, Articles in English and Spanish, published from January 2017 to June 2022. Fifteen articles were selected that met the criteria established for the review. Results: 60.0% of the studies reported that the rotary instrumentation had a better obturation quality than the manual one; 40.0% reported not finding statistically significant differences between both techniques. 100% of the studies indicated that there was a significant reduction in the instrumentation time of rotary files compared to manual files. Conclusion: the evidence indicates that both rotary and manual instrumentation are effective in guaranteeing the quality of root canal filling and that the instrumentation time is shorter with rotary instrumentation, this aspect being very important in pediatric dentistry since the patient the child spends less time in the chair, which contributes to his being more cooperative and the treatment time is reduced.

Comparative Biomonitoring of Arsenic Exposure in Mothers and Their Neonates in Comarca Lagunera, Mexico.

Multiple comorbidities related to arsenic exposure through drinking water continue to be public problems worldwide, principally in chronically exposed populations, such as those in the Comarca Lagunera (CL), Mexico. In addition, this relationship could be exacerbated by an early life exposure through the placenta and later through breast milk. This study conducted a comparative analysis of arsenic levels in multiple biological samples from pregnant women and their neonates in the CL and the comparison region, Saltillo. Total arsenic levels in placenta, breast milk, blood, and urine were measured in pregnant women and their neonates from rural areas of seven municipalities of the CL using atomic absorption spectrophotometry with hydride generation methodology. The average concentrations of tAs in drinking water were 47.7 µg/L and 0.05 µg/L in the exposed and non-exposed areas, respectively. Mean levels of tAs were 7.80 µg/kg, 77.04 µg/g-Cr, and 4.30 µg/L in placenta, blood, urine, and breast milk, respectively, in mothers, and 107.92 µg/g-Cr in neonates in the exposed group, which were significantly higher than those in the non-exposed area. High levels of urinary arsenic in neonates were maintained 4 days after birth, demonstrating an early arsenic exposure route through the placenta and breast milk. In addition, our study suggested that breastfeeding may reduce arsenic exposure in infants in arsenic-contaminated areas. Further studies are necessary to follow up on comorbidities later in life in neonates and to provide interventions in this region.

Modelos pedagógicos en Docentes de Ciencias Clínicas de la Universidad Tecnológica de Pereira-UTP, Colombia / Pedagogical models in Professors of Clinical Sciences of the Universidad Tecnológica de Pereira-UTP, Colombia

Resumen Objetivo: Caracterizar los modelos pedagógicos utilizados por los docentes de ciencias clínicas del programa de medicina de la Universidad Tecnológica de Pereira. Materiales y métodos: Investigación de tipo cualitativo, descriptivo. Se tomaron cuarenta docentes vinculados bajo cualquier modalidad (planta, transitorio o catedrático) que llevaran tres años o más realizando su actividad pedagógica. Se les realizó una entrevista semi-estructurada que fue avalada por el Comité de Bioética de la Universidad Tecnológica de Pereira. Resultados: El 55% de los docentes tienen formación en educación o docencia universitasirta. El 45% de los docentes aducen emplear el modelo problematizador, el 37,5% no conocen el modelo que emplean, el 12,5% creen utilizar el modelo tecnológico y por último el 5%, invocan el modelo tradicional. En cuanto al material didáctico utilizado no hubo diferencias entre los grupos de docentes, todos privilegiaron las ayudas audiovisuales tipo presentaciones en power point y expógrafo; tampoco hubo diferencias en cuanto a la metodología didáctica ya que la mayoría utilizaron rondas académicas, casos clínicos y revisiones de tema; en cuanto a la evaluación todos privilegiaron el examen escrito. Conclusión: La mayoría de los profesores tienen algún grado de formación en educación; todos utilizan un modelo pedagógico y aunque la mayoría lo identifican como modelo problematizador, se encontró que, con base en el material didáctico utilizado, la forma de transmitir la información, de motivar y evaluar al estudiante facilitar la formación, la tendencia es a usar una mezcla de los modelos, predominando el modelo tecnológico, seguido por los modelos tradicional y problematizador.

Abstract Objective: To characterize the pedagogical models used by the university professors of clinical sciences of the medicine program of the of the Universidad Tecnológica de Pereira. Materials and methods: Qualitative, descriptive research. Forty teachers linked under any modality (plant, transitory or for hours) who had been carrying out their pedagogical activity for three years or more were selected. A semi-structured interview was conducted, which was endorsed by the Bioethics Committee of the Universidad Tecnológica de Pereira. Results: 55% of professors have training in education or university teaching. 45% of teachers claim to use the problematization model, 37.5% do not know the model they use, 12.5% ​​believe they use the technological model and finally 5% invoke the traditional model. Regarding the didactic material used, there were no differences between the groups of teachers, all of whom favored audiovisual aids, such as power point presentations and whiteboard. There were also no differences regarding the didactic methodology since the majority used academic rounds, clinical cases, and topic reviews. And at the time of the evaluation, everyone favored the written exam. Conclusion: Most of the teachers have some degree of training in education; All of them use a pedagogical model and although the majority identify it as a problematization model, it was found that, based on the didactic material used, the way of transmitting information, motivating and evaluating the student and how it facilitates training, the tendency is to use a mixture of models, with the technological model predominating, followed by the traditional and problematization models.
